Background Art

The frame of current terminal electronic devices is mainly used as the antenna radiator. As the structural design of electronic devices gradually develops towards compactness and thinness, the challenge to antenna performance is gradually increasing. As the functions that electronic devices need to support increase, more requirements are put forward for the bandwidth, efficiency, and radiation pattern of antennas. The design space limitation of antennas in electronic devices restricts the performance of antennas.

Summary of the invention

The embodiments of the present application provide a camera decoration component and an electronic device, which are intended to utilize the internal space of the camera decoration component to set an antenna radiator, so as to release the antenna layout pressure on the frame of the electronic device and improve the antenna performance of the electronic device.

In a first aspect, a camera decoration assembly is provided. The camera decoration assembly includes a decoration body, the decoration body includes a metal part, at least part of the metal part forms a first radiator, and the camera decoration assembly is used to be installed in the housing of an electronic device. The first radiator includes a first feeding point and at least one first grounding point arranged at intervals, the first feeding point is used to electrically connect to a first feeding end of the electronic device, the first grounding point is used to electrically connect to a floor of the electronic device, the antenna device of the electronic device is used to communicate in a first frequency band, the first radiator is used to support communication in the first frequency band, and the antenna device and the first radiator are electrically connected to the same radio frequency chip.

It is understandable that the camera decoration assembly in this embodiment may include a decoration body. Among them, the decoration body may include a metal part. At least part of the metal part can be used to form a first radiator. The antenna device of the electronic device is used to operate in a first frequency band, and the first radiator can be used to support communication in the first frequency band, that is, the first radiator can be at the same frequency as the antenna device. The first radiator and the antenna device are electrically connected to the same RF chip, so that the first radiator and the antenna device can be used as receiving antennas with the same function, and diversity synthesis is performed through the same RF chip to achieve an improvement in antenna performance. At the same time, the first radiator is formed by at least part of the metal part of the decoration body, and the metal part of the decoration body can achieve "one thing for multiple uses", so that the first radiator can improve the antenna performance without occupying the limited antenna layout space in the side of the electronic device, which is conducive to releasing the antenna layout pressure of the frame of the electronic device.

In a possible implementation, the first frequency band corresponds to a satellite communication frequency band, and is used to support satellite messaging, and/or satellite phone calls, and/or satellite Internet access. In this way, by arranging the first radiator and the antenna device to be electrically connected to the same satellite communication chip/RF chip, the satellite communication performance of the electronic device is improved, thereby effectively improving the user experience when using the electronic device for satellite communication.

In a possible implementation, the frame of the electronic device is provided with a first frame radiator, the antenna device includes the first frame radiator, the first radiator is spaced apart from the first frame radiator, and the first frame radiator and the first radiator are electrically connected to the same RF chip. In this way, the first frame radiator and the first radiator are electrically connected to the same RF chip, and diversity synthesis is performed through the same RF chip to achieve improved antenna performance.

In a possible implementation, the first frame radiator is disposed on the top edge of the electronic device. In this way, when the first frame radiator is used as a satellite antenna radiator, the first frame radiator is disposed on the top edge of the electronic device, which is conducive to facilitating the user to perform antenna alignment, improve signal reception sensitivity, and enhance the user experience.

In a possible implementation, the electronic device further includes a first side and a second side, the first side and the second side are fixed on two sides opposite to the top side, the distance from the decorative part body to the first side is a first distance, the distance from the decorative part body to the second side is a second distance, and the ratio of the first distance to the second distance is in the range of 0.8 to 1.2. In this way, the decorative part body can be centered relative to the first side and the second side. When the first frame radiator is arranged at the top edge, the radiation pattern of the first radiator can be complementary to the radiation pattern of the first frame radiator, and the first radiator can synthesize a wide beam with the first frame radiator, so that the radiation formed by the first radiator and the first frame radiator can have better transmission and reception capabilities in a wider direction.

In a possible implementation, the first frame radiator has a first open end, a second open end, and a conductive portion extending between the first open end and the second open end in the length extension direction of the top edge, the distance from the center of the top edge to the first open end is the first spacing, the distance from the center of the top edge to the second open end is the second spacing, and the ratio of the first spacing to the second spacing is in the range of 0.8 to 1.2. In this way, the first frame radiator can be arranged on the top edge and located in the middle of the top edge. When the first frame radiator is a satellite antenna radiator, it is convenient for users to perform antenna alignment, improve signal reception sensitivity, and enhance user experience.

In a possible implementation manner, the antenna device and the first radiator are both used to receive signals in the first frequency band.

It is understandable that the first radiator and the antenna device can be used as receiving antennas with the same function, and diversity synthesis can be performed through the same radio frequency chip to achieve an extended directional pattern, or an extended beam, or an extended bandwidth, which is conducive to enhancing the electronic device's ability to receive signals in the first frequency band to achieve improved antenna performance. For example, when a user performs satellite communication, it is necessary to point the maximum radiation direction of the antenna to the satellite to achieve satellite alignment (that is, to establish a communication connection with the satellite). When the antenna beam is narrow (for example, less than ±10°), the antenna has high requirements for satellite alignment, and the attitude change of the electronic device has a greater impact on the quality of satellite communication. When the antenna beam is wide (for example, more than ±30°), the requirements for satellite alignment are lower, and the attitude change of the electronic device has a smaller impact on the quality of satellite communication. The directional pattern generated by the first radiator in this embodiment can complement the directional pattern generated by the antenna device, and a wide beam can be synthesized to expand the directional pattern and beam, which is conducive to reducing the requirements for satellite alignment of the electronic device during satellite communication, thereby effectively reducing the impact of the attitude change of the electronic device on the quality of satellite communication, and is conducive to improving the satellite communication performance of the electronic device. Among them, the antenna device and the first radiator are both used to receive signals in the satellite communication frequency band. In this way, the directional pattern generated by the first radiator can complement the directional pattern generated by the antenna device to synthesize a wide beam and widen the receiving beam, so that when the user uses the electronic device to receive satellite signals, the receiving sensitivity is higher, which is beneficial to enhancing the ability of the electronic device to receive signals and improving the user experience.

In a possible implementation, the camera decoration component further includes an inductor structure, which is connected in series between the second feeding point and the feeding end of the electronic device.

DETAILED DESCRIPTION

The following explains the terms that may appear in the embodiments of the present application.

It should be understood that the term "and/or" used in this article is only a description of the same field of the associated objects, indicating that there can be three relationships. For example, A and/or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character "/" in this article generally indicates that the associated objects before and after are in an "or" relationship.

When used in this application, “within the range of…”, unless it is separately specified that an end value is not included, it is assumed that both end values of the range are included. For example, in the range of 1 to 5, the two values 1 and 5 are included.

Coupling: can be understood as direct coupling and/or indirect coupling, and "coupled connection" can be understood as direct coupling connection and/or indirect coupling connection. Direct coupling can also be called "electrical connection", which is understood as the physical contact and electrical conduction between components; it can also be understood as the connection between different components in the circuit structure through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals; "indirect coupling" can be understood as two conductors being electrically conductive in an airless/non-contact manner. In one embodiment, indirect coupling can also be called capacitive coupling, for example, signal transmission is achieved by coupling between the gaps between two conductive parts to form an equivalent capacitor.

Component/device: includes at least one of lumped component/device and distributed component/device.

Lumped component/device: refers to the collective name for all components when the size of the component is much smaller than the wavelength relative to the circuit operating frequency. For the signal, regardless of any time, the component characteristics always remain fixed and are independent of frequency.

Distributed components/devices: Unlike lumped components, if the size of the component is similar to or larger than the wavelength relative to the circuit operating frequency, then when the signal passes through the component, the characteristics of each point of the component itself will vary due to changes in the signal. At this time, the component as a whole cannot be regarded as a single entity with fixed characteristics, but should be called a distributed component.

Capacitance: It can be understood as lumped capacitance and/or distributed capacitance. Lumped capacitance refers to capacitive components, such as capacitors; distributed capacitance (or distributed capacitance) refers to the equivalent capacitance formed by two conductive parts separated by a certain gap.

Inductance: It can be understood as lumped inductance and/or distributed inductance. Lumped inductance refers to inductive components, such as inductors; distributed inductance (or distributed inductance) refers to the equivalent inductance formed by a certain length of conductive parts.

Radiator: It is a device in the antenna used to receive/send electromagnetic wave radiation. In some cases, the "antenna" in a narrow sense is understood as a radiator, which converts the waveguide energy from the transmitter into radio waves, or converts radio waves into waveguide energy, which is used to radiate and receive radio waves. The modulated high-frequency current energy (or waveguide energy) generated by the transmitter is transmitted to the transmitting radiator via the feeder line, and is converted into a certain polarized electromagnetic wave energy by the radiator and radiated in the desired direction. The receiving radiator converts a certain polarized electromagnetic wave energy from a specific direction in space into modulated high-frequency current energy, which is transmitted to the receiver input via the feeder line.

The radiator may include a conductor with a specific shape and size, such as a linear or sheet shape, etc., and the present application does not limit the specific shape. In one embodiment, the linear radiator may be referred to as a linear antenna. In one embodiment, the linear radiator may be implemented by a conductive frame, and may also be referred to as a frame antenna. In one embodiment, the linear radiator may be implemented by a bracket conductor, and may also be referred to as a bracket antenna. In one embodiment, the linear radiator, or the radiator of the linear antenna, has a wire diameter (e.g., including thickness and width) much smaller than the wavelength (e.g., the dielectric wavelength) (e.g., less than 1/16 of the wavelength), and the length may be comparable to the wavelength (e.g., the dielectric wavelength) (e.g., the length is about 1/8 of the wavelength, or 1/8 to 1/4, or 1/4 to 1/2, or longer). The main forms of linear antennas are dipole antennas, half-wave oscillator antennas, monopole antennas, loop antennas, and inverted F antennas (also known as IFA, Inverted F Antenna). For example, for a dipole antenna, each dipole antenna generally includes two radiating branches, and each branch is fed by a feeding unit from the feeding end of the radiating branch. For example, an inverted-F antenna (IFA) can be regarded as a monopole antenna with a ground path added. The IFA antenna has a feeding point and a grounding point, and is called an inverted-F antenna because its side view is an inverted F shape. In one embodiment, the sheet radiator may include a microstrip antenna, or a patch antenna, such as a planar inverted F antenna (also known as PIFA, Planar Inverted F Antenna). In one embodiment, the sheet radiator may be implemented by a planar conductor (such as a conductive sheet or a conductive coating, etc.). In one embodiment, the sheet radiator may include a conductive sheet, such as a copper sheet, etc. In one embodiment, the sheet radiator may include a conductive coating, such as a silver paste, etc. The shape of the sheet radiator includes a circle, a rectangle, a ring, etc., and the present application does not limit the specific shape. The structure of the microstrip antenna is generally composed of a dielectric substrate, a radiator and a floor, wherein the dielectric substrate is arranged between the radiator and the floor.

The radiator may also include a slot or a slit formed on the conductor, for example, a closed or semi-closed slot or slit formed on a grounded conductor surface. In one embodiment, a slotted or slitted radiator may be referred to as a slot antenna or a slot antenna. In one embodiment, the radial dimension (e.g., including the width) of the slot or slit of the slot antenna/slot antenna is much smaller than the wavelength (e.g., the dielectric wavelength) (e.g., less than 1/16 of the wavelength), and the length dimension may be comparable to the wavelength (e.g., the dielectric wavelength) (e.g., the length is about 1/8 of the wavelength, or 1/8 to 1/4, or 1/4 to 1/2, or longer). In one embodiment, a radiator with a closed slot or slit may be referred to as a closed slot antenna. In one embodiment, a radiator with a semi-closed slot or slit (e.g., an opening is added to a closed slot or slit) may be referred to as an open slot antenna. In some embodiments, the slot shape is a long strip. In some embodiments, the length of the slot is about half a wavelength (e.g., the dielectric wavelength). In some embodiments, the length of the slot is about an integer multiple of the wavelength (e.g., one times the dielectric wavelength). In some embodiments, the slot can be fed by a transmission line connected across one or both sides thereof, thereby exciting a radio frequency electromagnetic field on the slot and radiating electromagnetic waves into space. In one embodiment, the radiator of the slot antenna or slot antenna can be realized by a conductive frame with both ends grounded, which can also be called a frame antenna; in this embodiment, it can be regarded as that the slot antenna or slot antenna includes a linear radiator, which is spaced apart from the floor and grounded at both ends of the radiator, thereby forming a closed or semi-closed slot or slot. In one embodiment, the radiator of the slot antenna or slot antenna can be realized by a bracket conductor with both ends grounded, which can also be called a bracket antenna.

The feed circuit is a combination of all circuits used for receiving and transmitting RF signals. The feed circuit may include a transceiver and an RF front end circuit. In some cases, the "feed circuit" is understood in a narrow sense as a RF chip (RFIC, Radio Frequency Integrated Circuit), and RFIC can be considered to include an RF front end chip and a transceiver. The feed circuit has the function of converting radio waves (e.g., RF signals) and electrical signals (e.g., digital signals). Usually, it is considered to be the RF part.

In some embodiments, the electronic device may further include a test socket (or referred to as a radio frequency socket or a radio frequency test socket). The test socket may be used to insert a coaxial cable to test the characteristics of the radio frequency front-end circuit or the radiator of the antenna through the cable. The radio frequency front-end circuit may be considered as a circuit portion coupled between the test socket and the transceiver.

In some embodiments, the RF front-end circuit may be integrated into a RF front-end chip in the electronic device, or the RF front-end circuit and the transceiver may be integrated into a RF chip in the electronic device.

It should be understood that any two of the first/second/...Nth feeding circuits in the present application may share the same transceiver, for example, transmitting signals through a radio frequency channel in a transceiver (for example, a port (pin) of a radio frequency chip); and may also share a radio frequency front-end circuit, for example, processing signals through a tuning circuit or amplifier in a radio frequency front-end.

It should also be understood that two feeding circuits in the first/second/...Nth feeding circuits in the present application usually correspond to two radio frequency test sockets in the electronic device.

A matching circuit is a circuit used to adjust the radiation characteristics of an antenna. In one embodiment, the matching circuit is coupled between a feed circuit and a corresponding radiator. In one embodiment, the matching circuit is coupled between a test socket and a radiator. Typically, a matching circuit is a combination of circuits coupled between a radiator and a floor. In one embodiment, the matching circuit may include a tuning circuit and/or an electronic component, and the tuning circuit may be an electronic component used to switch the coupling connection of the radiator. The matching circuit has the functions of impedance matching and/or frequency tuning. Typically, it is considered to be a part of the antenna.

The grounding structure/feeding structure may include a connector, such as a metal spring, and the radiator is coupled to the floor through the grounding structure/feeding structure is coupled to the feeding circuit. In some embodiments, the feeding structure may include a transmission line/feeding line, and the grounding structure may include a grounding line.

End/point: The "end/point" in the first end/second end/feeding end/grounding end/feeding point/grounding point/connection point of the antenna radiator cannot be narrowly understood as an end point or end that is physically disconnected from other radiators, and can also be considered as a point or a section on a continuous radiator. In one embodiment, the "end/point" may include a connection/coupling area on the antenna radiator that is coupled to other conductive structures. For example, the feeding end/feeding point may be a coupling area on the antenna radiator that is coupled to a feeding structure or a feeding circuit (for example, an area facing a part of the feeding circuit). For another example, the grounding end/grounding point may be a connection/coupling area on the antenna radiator that is coupled to a grounding structure or a grounding circuit. Open end, closed end: In some embodiments, the open end and the closed end are, for example, relative to whether they are grounded. The closed end is grounded and the open end is not grounded. In some embodiments, the open end and the closed end are, for example, relative to other conductors. The closed end is electrically connected to other conductors, and the open end is not electrically connected to other conductors. In one embodiment, the open end may also be referred to as a floating end, a free end, an open end, or an open circuit end. In one embodiment, the closed end may also be referred to as a ground end or a short circuit end. It should be understood that in some embodiments, other conductors may be coupled and connected through the open end to transfer coupling energy (which may be understood as transferring current).

In some embodiments, the "closed end" can also be understood from the perspective of current distribution. The closed end or the grounded end, etc., can be understood as a point with larger current on the radiator, or as a point with smaller electric field on the radiator. In one embodiment, the current distribution characteristics of larger current/small electric field can be maintained by coupling electronic devices (for example, capacitors, inductors, etc.) through the closed end. In one embodiment, the current distribution characteristics of larger current/small electric field can be maintained by opening a gap at or near the closed end (for example, a gap filled with insulating material).

In some embodiments, the "open end" can also be understood from the perspective of current distribution. The open end or suspended end, etc., can be understood as a point with smaller current on the radiator, or as a point with larger electric field on the radiator. In one embodiment, coupling electronic devices (for example, capacitors, inductors, etc.) through the open end can maintain the current distribution characteristics of the smaller current point/larger electric field point.

It should be understood that coupling the radiator end at a gap (from the perspective of the structure of the radiator, it is similar to a radiator at an opening of an open end or a suspended end) with electronic devices (for example, capacitors, inductors, etc.) can make the radiator end a point with larger current/smaller electric field. In this case, it should be understood that the radiator end at the gap is actually a closed end or a grounded end, etc.

The “suspended radiator” mentioned in the embodiments of the present application means that the radiator is not directly connected to the feeder line/feeder branch and/or the grounding line/grounding branch, but is fed and/or grounded through indirect coupling.

It should be understood that the "suspended" in "suspended end" or "suspended radiator" does not mean that there is no structure around the radiator to support it. In one embodiment, the suspended radiator can be, for example, a radiator disposed on the inner surface of the insulating back cover.

The current same direction/reverse direction mentioned in the embodiments of the present application should be understood as the direction of the main current on the conductor on the same side is the same direction/reverse direction. For example, when stimulating a distributed current in the same direction on a conductor that is bent or annular (for example, the current path is also bent or annular), it should be understood that, for example, the main current stimulating on the conductors on both sides of the annular conductor (for example, a conductor surrounding a gap, on the conductors on both sides of the gap) is opposite in direction, but it still belongs to the definition of the distributed current in the same direction in the embodiments of the present application. In one embodiment, the current same direction on a conductor may refer to the current on the conductor having no reverse point. In one embodiment, the current reverse on a conductor may refer to the current on the conductor having at least one reverse point. In one embodiment, the current same direction on two conductors may refer to the current on both conductors having no reverse point and flowing in the same direction. In one embodiment, the current reverse on two conductors may refer to the current on both conductors having no reverse point and flowing in opposite directions. The current same direction/reverse direction on multiple conductors can be understood accordingly.

Resonance/resonance frequency: The resonance frequency is also called the resonance frequency. The resonance frequency can have a frequency range, that is, the frequency range in which resonance occurs. The frequency corresponding to the strongest resonance point is the center frequency point frequency. The return loss characteristic of the center frequency can be less than -20dB. It should be understood that, unless otherwise specified, the antenna/radiator mentioned in this application produces a "first/second... resonance", where the first resonance should be the fundamental mode resonance generated by the antenna/radiator, or in other words, the lowest frequency resonance generated by the antenna/radiator. It should be understood that the antenna/radiator can generate one or more antenna modes according to the specific design, and each antenna mode can correspond to a fundamental mode resonance.

Resonant frequency band: The range of the resonant frequency is the resonant frequency band. The return loss characteristic of any frequency point in the resonant frequency band can be less than -6dB or -5dB.

Communication frequency band/working frequency band: Regardless of the type of antenna, it always works within a certain frequency range (band width). For example, an antenna that supports the B40 frequency band has a working frequency band that includes frequencies in the range of 2300MHz to 2400MHz, or in other words, the working frequency band of the antenna includes the B40 frequency band. The frequency range that meets the index requirements can be regarded as the working frequency band of the antenna.

The resonant frequency band and the operating frequency band may be the same, or may partially overlap. In one embodiment, one or more resonant frequency bands of the antenna may cover one or more operating frequency bands of the antenna.

Electrical length: It can refer to the ratio of physical length (ie mechanical length or geometric length) to the wavelength of the transmitted electromagnetic wave. The electrical length can satisfy the following formula:

Where L is the physical length and λ is the wavelength of the electromagnetic wave.

Wavelength: or operating wavelength, which can be the wavelength corresponding to the center frequency of the resonant frequency or the center frequency of the operating frequency band supported by the antenna. For example, assuming that the center frequency of the B1 uplink frequency band (resonant frequency is 1920MHz to 1980MHz) is 1955MHz, then the operating wavelength can be the wavelength calculated using the frequency of 1955MHz. Not limited to the center frequency, "operating wavelength" can also refer to the wavelength corresponding to the non-center frequency of the resonant frequency or the operating frequency band.

It should be understood that the wavelength of the radiation signal in the air can be calculated as follows: (wavelength in air, or wavelength in vacuum) = speed of light/frequency, where frequency is the frequency of the radiation signal (MHz), and the speed of light can be taken as 3×108 m/s. The wavelength of the radiation signal in the medium can be calculated as follows: Among them, ε is the relative dielectric constant of the medium. The wavelength in the embodiments of the present application generally refers to the dielectric wavelength, which can be the dielectric wavelength corresponding to the center frequency of the resonant frequency, or the dielectric wavelength corresponding to the center frequency of the working frequency band supported by the antenna. For example, assuming that the center frequency of the B1 uplink frequency band (resonant frequency is 1920MHz to 1980MHz) is 1955MHz, the wavelength can be the dielectric wavelength calculated using the frequency of 1955MHz. Not limited to the center frequency, "dielectric wavelength" may also refer to the dielectric wavelength corresponding to the non-center frequency of the resonant frequency or the working frequency band. For ease of understanding, the dielectric wavelength mentioned in the embodiments of the present application can be simply calculated by the relative dielectric constant of the medium filled on one or more sides of the radiator.

Antenna system efficiency (total efficiency): refers to the ratio of input power to output power at the antenna port.

Antenna radiation efficiency: refers to the ratio of the power radiated by the antenna into space (i.e. the power of the electromagnetic wave part that is effectively converted) to the active power input to the antenna. Among them, the active power input to the antenna = the input power of the antenna - the loss power; the loss power mainly includes the return loss power and the ohmic loss power of the metal and/or the dielectric loss power. The radiation efficiency is a value that measures the radiation ability of the antenna. Metal loss and dielectric loss are both factors that affect the radiation efficiency.

Those skilled in the art can understand that efficiency is generally expressed as a percentage, and there is a corresponding conversion relationship between efficiency and dB. The closer the efficiency is to 0 dB, the better the efficiency of the antenna.

Antenna return loss: It can be understood as the ratio of the signal power reflected back to the antenna port through the antenna circuit to the transmit power of the antenna port. The smaller the reflected signal, the larger the signal radiated into space through the antenna, and the greater the radiation efficiency of the antenna. The larger the reflected signal, the smaller the signal radiated into space through the antenna, and the lower the radiation efficiency of the antenna.

Antenna return loss can be represented by the S11 parameter, which is one of the S parameters. S11 represents the reflection coefficient, which can characterize the antenna transmission efficiency. The S11 parameter is usually a negative number. The smaller the S11 parameter is, the smaller the antenna return loss is, and the less energy is reflected back by the antenna itself, which means that more energy actually enters the antenna, and the higher the antenna system efficiency is; the larger the S11 parameter is, the greater the antenna return loss is, and the lower the antenna system efficiency is.

It should be noted that in engineering, the S11 value is generally -6dB as the standard. When the S11 value of an antenna is less than -6dB, it can be considered that the antenna can work normally, or that the antenna has good transmission efficiency.

Antenna pattern: also called radiation pattern. It refers to the graph of the relative field strength (normalized modulus) of the antenna radiation field changing with direction at a certain distance from the antenna (far field). It is usually represented by two mutually perpendicular plane patterns in the direction of maximum radiation of the antenna.

Antenna radiation patterns usually have multiple radiation beams. The radiation beam with the strongest radiation intensity is called the main lobe, and the remaining radiation beams are called side lobes or side lobes. Among the side lobes, the side lobe in the opposite direction of the main lobe is also called the back lobe.

Directivity: Also known as the directivity of an antenna. It refers to the ratio of the maximum power density to the average value on the antenna pattern at a certain distance from the antenna (far field), which is a dimensionless ratio greater than or equal to 1. It can be used to indicate the energy radiation characteristics of an antenna. The larger the directivity, the more energy the antenna radiates in a certain direction, and the more concentrated the energy radiation.

Antenna gain: It is used to characterize the degree to which the antenna radiates the input power. Generally, the narrower the main lobe of the antenna pattern and the smaller the side lobe, the higher the antenna gain.

Polarization direction of the antenna: At a given point in space, the electric field strength E (vector) is a function of time t. As time goes by, the endpoints of the vector periodically draw a trajectory in space. If the trajectory is straight and perpendicular to the ground, it is called vertical polarization. If it is horizontal to the ground, it is called horizontal polarization. When the trajectory is elliptical or circular, when observed along the propagation direction, it rotates in the right hand or clockwise direction over time, which is called right-hand circular polarization (RHCP). If it rotates in the left hand or counterclockwise direction over time, it is called left-hand circular polarization (LHCP).

Ground (GND): It can refer to at least a part of any grounding layer, grounding plate, or grounding metal layer in an electronic device (such as a mobile phone), or at least a part of any combination of any of the above grounding layers, grounding plates, or grounding components. "Ground" can be used for grounding components in electronic devices. In one embodiment, "ground" can be the grounding layer of the circuit board of the electronic device, or it can be the grounding plate formed by the frame of the electronic device or the grounding metal layer formed by the metal film under the screen. In one embodiment, the circuit board can be a printed circuit board (PCB), such as an 8-layer, 10-layer or 12 to 14-layer board with 8, 10, 12, 13 or 14 layers of conductive materials, or an element separated and electrically insulated by a dielectric layer or insulating layer such as glass fiber, polymer, etc. In one embodiment, the circuit board includes a dielectric substrate, a grounding layer and a routing layer, and the routing layer and the grounding layer are electrically connected through vias. In one embodiment, components such as a display, a touch screen, an input button, a transmitter, a processor, a memory, a battery, a charging circuit, a system on chip (SoC) structure, etc. can be mounted on or connected to a circuit board; or electrically connected to a wiring layer and/or a ground layer in the circuit board. For example, a radio frequency source is disposed in the wiring layer.

Any of the above-mentioned grounding layers, grounding plates, or grounding metal layers are made of conductive materials. In one embodiment, the conductive material can be any of the following materials: copper, aluminum, stainless steel, brass and their alloys, copper foil on an insulating substrate, aluminum foil on an insulating substrate, gold foil on an insulating substrate, silver-plated copper, silver-plated copper foil on an insulating substrate, silver foil and tin-plated copper on an insulating substrate, cloth impregnated with graphite powder, graphite-coated substrates, copper-plated substrates, brass-plated substrates, and aluminum-plated substrates. It will be appreciated by those skilled in the art that the grounding layer/grounding plate/grounding metal layer can also be made of other conductive materials.

Grounding: refers to coupling with the above-mentioned ground/floor in any way. In one embodiment, grounding can be achieved through physical grounding, such as physical grounding (or physical ground) at a specific position on the frame through some structural parts of the middle frame. In one embodiment, grounding can be achieved through device grounding, such as grounding through devices such as capacitors/inductors/resistors connected in series or in parallel (or device ground).

In the embodiments of the present application, the range of/between values mentioned herein includes the endpoint values of the range unless otherwise specified. For example, the range of 2 to 10 includes the two endpoint values of 2 and 10.

The following will introduce the two antenna modes involved in this application in conjunction with Figures 1a to 1d. Among them, Figure 1a is the structure of a common mode mode of an antenna 91 provided in this application. Figure 1b is a schematic diagram of the distribution of current and electric field corresponding to the common mode mode of the antenna 91 shown in Figure 1a. Figure 1c is the structure of a differential mode mode of another antenna 92 provided in this application. Figure 1d is a schematic diagram of the distribution of current and electric field corresponding to the differential mode mode of the antenna 92 shown in Figure 1c. The antenna radiator in Figures 1a to 1d is open at both ends, and its common mode mode and differential mode can be called a line common mode mode and a line differential mode mode, respectively.

It should be understood that the “common-differential mode” or “CM-DM mode” in the present application refers to a line common mode mode and a line differential mode mode generated on the same radiator.

1. Wire common mode (CM) mode

FIG. 1a shows that the radiator of antenna 91 is open at both ends, and a feeding circuit (not shown) is connected at the middle position 911. In one embodiment, the feeding form of antenna 91 adopts symmetrical feed. The feeding circuit can be connected to the middle position 911 of antenna 91 through a feeding line 912. It should be understood that symmetrical feeding can be understood as one end of the feeding circuit is connected to the radiator, and the other end is coupled to the floor to achieve grounding, wherein the connection point between the feeding circuit and the radiator (feeding point) is located at the center of the radiator, and the center of the radiator can be, for example, the midpoint of the geometric structure, or the midpoint of the electrical length (or an area within a certain range near the above midpoint).

The middle position 911 of the antenna 91 may be, for example, the geometric center of the antenna, or the midpoint of the electrical length of the radiator. For example, the connection between the feed line 912 and the antenna 91 covers the middle position 911 .

FIG1b shows the current and electric field distribution of the antenna 91. As shown in FIG1b , the current is distributed in opposite directions on both sides of the middle position 911, for example, symmetrically; the electric field is distributed in the same direction on both sides of the middle position 911. As shown in FIG1b , the current at the feeder 912 is distributed in the same direction. Based on the same-direction distribution of the current at the feeder 912, the feeding shown in FIG1a can be called line CM feeding. Based on the opposite distribution of the current on both sides of the connection between the radiator and the feeder 912, the antenna mode shown in FIG1b can be called a line CM mode (it can also be referred to as a CM mode for short. For example, for a line antenna, the CM mode refers to a line CM mode). The current and electric field shown in FIG1b can be respectively referred to as the current and electric field of the line CM mode.

The current is stronger at the middle position 911 of the antenna 91 (the current is stronger near the middle position 911 of the antenna 91) and weaker at both ends of the antenna 91, as shown in FIG1b. The electric field is weaker at the middle position 911 of the antenna 91 and stronger at both ends of the antenna 91.

2. Line differential mode (DM) mode

As shown in FIG. 1c , the left and right ends of the two radiators of the antenna 92 are open ends, and the feeding circuit is connected at the middle position 921. In one embodiment, the feeding form of the antenna 92 adopts anti-symmetrical feed. One end of the feeding circuit is connected to one of the radiators through the feeding line 922, and the other end of the feeding circuit is connected to the other radiator through the feeding line 922. The middle position 921 can be the geometric center of the antenna 92, or the gap formed between the radiators.

It should be understood that the "center antisymmetric feeding" mentioned in this application can be understood as that the positive and negative poles of the feeding unit are respectively connected to two connection points near the above-mentioned midpoint of the radiator. In one embodiment, the positive and negative poles of the feeding unit output signals with the same amplitude and opposite phases, for example, the phase difference is 180°±10°.

FIG. 1d shows the current and electric field distribution of the antenna 92. As shown in FIG. 1d, the current is distributed in the same direction on both sides of the middle position 921 of the antenna 92, such as an antisymmetric distribution; the electric field is distributed in the opposite direction on both sides of the middle position 921. As shown in FIG. 1d, the current at the feed line 922 is distributed in the opposite direction. Based on the opposite distribution of the current at the feed line 922, the feeding shown in FIG. 1c can be called line DM feeding. Based on the current being distributed in the same direction on both sides of the connection between the radiator and the feed line 922, the antenna mode shown in FIG. 1d can be called a line DM mode (also referred to as a DM mode for short, for example, for a line antenna, the DM mode refers to a line DM mode). The current and electric field shown in FIG. 1d can be referred to as the current and electric field of the line DM mode, respectively. It should be understood that based on the current being distributed in the same direction on both sides of the connection between the radiator and the feed line 922, the antenna mode shown in FIG. 1d can also be called a half antenna mode, or a half wavelength mode, or simply a half mode.

In one embodiment, in the online DM mode, or half mode, the current is stronger at the middle position 921 of the antenna 92 (the current is larger near the middle position 921 of the antenna 92), and weaker at both ends of the antenna 92, as shown in FIG1d. The electric field is weaker at the middle position 921 of the antenna 92, and stronger at both ends of the online antenna 92.

It should be understood that the antenna radiator can be understood as a metal structure that generates radiation, and the number of the radiator can be one, as shown in FIG. 1a and FIG. 1b, or two, as shown in FIG. 1c and FIG. 1d, which can be adjusted according to actual design or production needs. For example, for the line CM mode, two radiators can be used as shown in FIG. 1c and FIG. 1d, and the two ends of the two radiators are arranged opposite to each other and separated by a gap. A symmetrical feeding method is adopted at the two ends close to each other, for example, the same feed source signal is fed into the two ends close to each other, and an effect similar to the antenna structure shown in FIG. 1a and FIG. 1b can also be obtained. Correspondingly, for the line DM mode, a radiator can also be used as shown in FIG. 1a and FIG. 1b, and two feeding points are set in the middle position of the radiator and an anti-symmetric feeding method is adopted. For example, if two symmetrical feeding points on the radiator are fed with signals with the same amplitude and opposite phases, an effect similar to the antenna structure shown in FIG. 1c and FIG. 1d can also be obtained.

3. Line CM-DM mode

FIG. 1a and FIG. 1b above respectively show that when both ends of the radiator are open, a line CM mode and a line DM mode are generated by using different feeding methods.

When the antenna is fed in an asymmetric manner (the feeding point is offset from the middle of the radiator, including side feeding or offset feeding), or the grounding point of the radiator (where it is coupled with the floor) is asymmetric (the grounding point is offset from the middle of the radiator), the antenna can simultaneously generate the first resonance and the second resonance, corresponding to the line CM mode and the line DM mode, respectively. For example, the first resonance corresponds to the line CM mode, and the current and electric field distribution are shown in Figure 1b. The second resonance corresponds to the line DM mode, and the current and electric field distribution are shown in Figure 1d.

It is to be understood that the specific embodiments described herein are only used to explain the relevant inventions, rather than to limit the inventions. It should also be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings. The technical solutions of the embodiments of the present application will be described below in conjunction with the accompanying drawings.

Fig. 2a is a schematic diagram of the structure of the electronic device 1000 provided in some embodiments of the present application. Fig. 2b is a schematic diagram of the structure of the electronic device 1000 shown in Fig. 2a from another perspective. Fig. 2c is a schematic diagram of the partially exploded structure of the electronic device 1000 shown in Fig. 2a in some embodiments.

As shown in Figures 2a to 2c, the electronic device 1000 can be a mobile phone, a tablet computer, an e-reader, a laptop computer, a wearable device such as a watch, and other electronic devices with a shooting function. The electronic device 1000 of the embodiment shown in Figure 2a is described by taking a mobile phone as an example. For ease of description, the thickness direction of the electronic device 1000 is defined as the Z axis, the length direction of the electronic device 1000 is defined as the Y axis, and the width direction of the electronic device 1000 is defined as the X axis. It is understandable that the coordinate system of the electronic device 1000 can also be specifically set according to actual needs, and this application does not limit this.

Exemplarily, the electronic device 1000 may include a screen 200 and a housing 300. It is understood that Figures 2a to 2c only schematically illustrate some components included in the electronic device 1000, and the actual shape, actual size and actual structure of these components are not limited by Figures 2a to 2c. In other embodiments, when the electronic device 1000 is a device of other forms, the electronic device 1000 may not include a screen 200. Among them, the screen 200 can be installed in the housing 300. Figures 2a and 2b illustrate that the screen 200 and the housing 300 form a roughly rectangular parallelepiped structure. The screen 200 can be used to display images, text, etc. It should be understood that in the embodiments of the present application, it can be considered that when the user holds (usually vertically and facing the screen 200) the electronic device 1000, the position of the electronic device 1000 has a top, a bottom, a left side and a right side. Among them, the top of the electronic device 1000 can face the sky. In this embodiment, the arrangement direction of the top and the bottom can be parallel to the Y-axis direction. The arrangement direction of the left side portion and the right side portion may be parallel to the X-axis direction.

Exemplarily, the housing 300 can be used to support the screen 200 and related devices of the electronic device 1000. The housing 300 may include a middle frame 310 (housing) and a rear cover 320 (rear cover). The rear cover 320 and the screen 200 may be installed on opposite sides of the middle frame 310. The arrangement direction of the rear cover 320 and the screen 200 may be parallel to the Z-axis direction. The rear cover 320 may be fixedly connected to the middle frame 310 by bonding, welding, etc. At this time, the screen 200, the middle frame 310, and the rear cover 320 may together enclose the internal space of the electronic device 1000. The internal space of the electronic device 1000 may be used to place the internal devices of the electronic device 1000, such as a battery, a speaker, a microphone, or a receiver. Among them, the rear cover 320 may be a rear cover 320 made of a metal material, or a rear cover 320 made of a non-conductive material, such as a non-metallic rear cover such as a glass rear cover or a plastic rear cover, or a rear cover 320 made of both a conductive material and a non-conductive material.

Exemplarily, the middle frame 310 may include a frame 311 and a middle plate 312. The frame 311 may be arranged around the middle plate 312 and connected to the middle plate 312. The frame 311 may be formed of a conductive material such as metal. In this case, the frame 311 is a metal frame. In some embodiments, the middle frame 310 may also include only the frame 311. The back cover 320 may be an integrally formed structure with the frame 311, that is, the back cover 320 and the frame 311 are a whole.

As shown in FIG. 2c , the electronic device 1000 may further include a circuit board 400. The circuit board 400 may be a printed circuit board (PCB). The circuit board 400 may be located between the middle frame 310 and the back cover 320. The circuit board 400 may carry electronic components, such as radio frequency chips, etc. Among them, the circuit board 400 may adopt a flame retardant material (FR-4) dielectric board, a Rogers dielectric board, or a mixed dielectric board of Rogers and FR-4, etc. It should be noted that FR-4 is a code for a grade of flame retardant material, and the Rogers dielectric board is a high-frequency board. In some embodiments, the circuit board 400 may also be located between the screen 200 and the middle frame 310. This application does not limit the specific position of the circuit board 400.

In some embodiments, a metal layer may be further provided on the circuit board 400. The metal layer may be used for grounding electronic components carried on the circuit board 400, and may also be used for grounding other components in the electronic device 1000 (e.g., a bracket antenna, a frame antenna, etc.). In this case, the metal layer may be referred to as a floor, or a grounding plate, or a grounding layer. Exemplarily, the edge of the circuit board 400 may be regarded as the edge of its floor.

In some embodiments, the conductive parts in the middle frame 310 and/or the back cover 320 may also serve as the reference ground of the electronic device 1000. Devices such as circuit boards in the electronic device 1000 may be grounded by being electrically connected to the middle frame 310 and/or the back cover 320. In other embodiments, the electronic device 1000 may also have other ground planes, which will not be described in detail herein.

FIG. 3 is a schematic structural diagram of the frame 311 of the electronic device 1000 shown in FIG. 2 c .

As shown in FIG3 , the frame 311 of the electronic device 1000 may be a metal frame. The frame 311 may include a first short side 3111 and a second short side 3112 disposed oppositely, and a first long side 3113 and a second long side 3114 disposed oppositely. The first short side 3111 and the second short side 3112 may be connected between the first long side 3113 and the second long side 3114. An angle (e.g., a 90° angle) may be formed between the first long side 3113 and the first short side 3111. The length of the first long side 3113 may be greater than the length of the first short side 3111. It should be understood that the length of the first long side 3113 refers to the size of the first long side 3113 in its extension direction. The length of the first short side 3111 refers to the size of the first short side 3111 in its extension direction. In some embodiments, the first long side 3113, the second long side 3114, the first short side 3111, and the second short side 3112 may all be in the shape of long strips. The frame 311 may also include a plurality of corners (not shown). Any two adjacent ones of the first long side 3113, the second long side 3114, the first short side 3111 and the second short side 3112 may be transitionally connected through a corner. In some other embodiments, any corner of the frame 311 may also be considered as a part of the long side or short side adjacent to the corner.

In this embodiment, when the user holds the electronic device 1000 (see FIG. 2a ), the first short side 3111 may be located at the top of the electronic device 1000. The second short side 3112 may be located at the bottom of the electronic device 1000. The first long side 3113 may be located at the left side of the electronic device 1000. The second long side 3114 may be located at the right side of the electronic device 1000.

It should be noted that the frame 311 shown in FIG3 is described by taking the non-foldable electronic device 1000 as an example. When the electronic device 1000 is a foldable electronic device 1000 (for example, a multi-fold device such as a two-fold or three-fold device), the first long side 3113, the second long side 3114, the first short side 3111, and the second short side 3112 can be correspondingly understood as the long side and the short side on the part of the frame corresponding to one of the multiple folds.

FIG. 4 is a partially enlarged schematic structural diagram of the structure shown in FIG. 3 .

As shown in FIG. 4 , the electronic device 1000 may include an antenna device 500. The antenna device 500 may include at least one radiator. The antenna device 500 may use the conductive portion of the frame 311 of the electronic device 1000 as a main radiator and/or a parasitic branch. In one embodiment, the outer surface of the frame 311 may be a conductive material, such as a metal material, so as to form the appearance of a metal frame, which is suitable for a metal industrial design (ID). In these embodiments, the conductive portion of the frame 311 (e.g., including the outer surface of the frame 311) may be used as a radiator of the antenna device 500.

In one embodiment, the outer surface of the frame 311 may be a non-conductive material, such as plastic, to form the appearance of a non-metallic frame, which is suitable for non-metallic ID. The inner surface of the frame 311 may include a conductive material, such as a metal material. In these embodiments, the conductive portion of the frame 311 (for example, including the inner surface of the frame 311) can be used as a radiator of the antenna device 500. It should be understood that the radiator (or the conductive material on the inner surface) disposed on the inner surface of the frame 311 is arranged in close contact with the non-conductive material of the frame 311 to minimize the volume occupied by the radiator and is closer to the outside of the electronic device 1000 to achieve better signal transmission effect. It should be noted that the arrangement of the antenna radiator against the non-conductive material of the frame 11 means that the antenna radiator can be arranged close to the inner surface of the non-conductive material, or it can be arranged embedded in the non-conductive material, or it can be arranged close to the inner surface of the non-conductive material, for example, there can be a certain small gap between the antenna radiator and the inner surface of the non-conductive material. It should be understood that both the conductive material and the non-conductive material can be regarded as part of the frame 11. The antenna radiator arranged on the non-conductive material close to the frame 11 can also become the frame radiator.

Exemplarily, the first short side 3111 may be provided with a first slit 311a and a second slit 311b. The first slit 311a and the second slit 311b may divide a metal segment on the first short side 3111 to form the first frame radiator 510 of the antenna device 500. The first slit 311a and the second slit 311b may be filled with insulating materials, for example, the insulating materials may be materials such as polymers, glass, ceramics, or a combination of these materials. In other embodiments, the material of the first short side 3111 may also be a non-conductive material. At this time, the first short side 3111 may not be provided with the first slit 311a and the second slit 311b. The first frame radiator 510 may be a conductor mounted on the first short side 3111, such as an antenna radiator such as an FPC antenna or an LDS antenna. In some embodiments, the width of the first slit 311a/the second slit 311b may be in the range of 0.1 mm to 2 mm. It should be understood that the width of the slits opened on the frame 311 in the embodiments of the present application may be within the above range. In some other implementations, the first frame radiator 510 may also be disposed on the first long side 3113.

In other embodiments, the first end 511 may be an open end, and the second end 512 may be a ground end.

Exemplarily, the first frame radiator 510 may include a first feeding point 514. The antenna device 500 may further include a feed source 520. The feed source 520 may be electrically connected to the first feeding point 514.

Exemplarily, the first frame radiator 510 may include a first grounding point 513. The first frame radiator 510 may be coupled to the floor at the first grounding point 513. The floor may be a metal layer on the circuit board 400 and/or the middle frame 310 (please refer to FIG. 2c ). It should be understood that in the embodiments of the present application, the coupling connection is only illustrated by taking electrical connection as an example. In actual production or practice, it can also be achieved by indirect coupling. For the sake of simplicity of discussion, they will not be described one by one. In other embodiments, the first frame radiator 510 may also not include the first grounding point 513. FIG. 4 only illustrates the case where the first frame radiator 510 includes the first grounding point 513.

Exemplarily, the antenna device 500 can be used to receive or transmit signals in a communication frequency band for satellite messages and/or satellite phones. The working frequency band of the antenna device 500 may include a satellite communication frequency band. Satellite communications include at least one of satellite receiving and/or sending short messages (also known as short messages), satellite calls and/or answering calls, and satellite data (such as Internet access). That is, the first frame radiator 510 can be used to receive/send signals in a satellite communication frequency band. At this time, the first short side 3111 can be regarded as the top side of the electronic device 1000. The second short side 3112 can be regarded as the bottom side of the electronic device 1000. The first long side 3113 can be regarded as the first side of the electronic device 1000. The second long side 3114 can be regarded as the second side of the electronic device 1000. In other embodiments, the first frame radiator 510 can also be located on the first long side 3113. At this time, the first long side 3113 can be regarded as the top side of the electronic device 1000. The first short side 3111 and the second short side 3112 can be respectively regarded as the first side and the second side of the electronic device 1000. In other words, the side where the satellite antenna radiator (ie, the first frame radiator 510 in this embodiment) is located can be regarded as the top side of the electronic device 1000.

In one embodiment, the satellite communication frequency band may include part of the frequency band in the Tiantong satellite system, for example, it may include the transmit frequency band (1980MHz-2010MHz) and the receive frequency band (2170MHz-2200MHz) in the Tiantong satellite system. In one embodiment, the satellite communication frequency band may include part of the frequency band in the Beidou satellite system, for example, it may include the transmit frequency band (1610MHz-1626.5MHz) and the receive frequency band (2483.5MHz-2500MHz) in the Beidou satellite system. In one embodiment, the antenna device 500 may be a low-orbit satellite communication antenna.

Alternatively, the antenna device 500 may also be a medium-orbit satellite communication antenna with an operating frequency band of 4GHz-6GHz. In other embodiments, the antenna device 500 may also be applied to other satellite communication systems, and the embodiments of the present application are not limited thereto.

As shown in FIGS. 5 to 7 , the electronic device 1000 may further include a camera decoration assembly 100 and a camera module 600 (FIG. 3 also illustrates the camera decoration assembly 100 and the camera module 600). The back cover 320 may be provided with a light-transmitting hole 321. The camera module 600 may be mounted on the side of the middle frame 310 facing away from the screen 200. The light inlet of the camera module 600 may be exposed relative to the light-transmitting hole 321 of the back cover 320. The camera decoration assembly 100 may be fixed to the back cover 320. At least part of the camera decoration assembly 100 may cover the light-transmitting hole 321. In this embodiment, the camera decoration assembly 100 may be located in the middle of the first side (i.e., the first long side 3113 in this embodiment) and the second side (i.e., the second long side 3114 in this embodiment), and may be arranged close to the top side (i.e., the first short side 3111 in this embodiment). That is, the camera decoration component 100 may be located at the upper middle portion of the rear cover 320 (see FIG. 2 b ). In other embodiments, the camera decoration component 100 may also be disposed closer to the second side edge relative to the first side edge.

Exemplarily, the camera decoration assembly 100 may include a decoration body 10 and a protective cover plate 20. The decoration body 10 may be roughly sheet-shaped or plate-shaped. The decoration body 10 may be fixedly connected to the back cover 320. The decoration body 10 may be spaced apart from the middle plate 312 of the middle frame 310 and the circuit board 400. At least part of the decoration body 10 may cover the avoidance hole of the back cover 320. Among them, the decoration body 10 may be arranged opposite to the circuit board 400 and/or the middle plate 312 of the middle frame 310. In this embodiment, the decoration body 10 may be arranged opposite to the circuit board 400.

Exemplarily, the decorative part body 10 may be provided with an avoidance hole 10a. The avoidance hole 10a may be arranged opposite to the light inlet hole of the camera module 600. Exemplarily, the number of camera modules 600 may be multiple. The number of avoidance holes 10a may also be multiple. Multiple avoidance holes 10a may be arranged opposite to the light inlet holes of multiple camera modules 600 in a one-to-one correspondence. Among them, the shapes and sizes of the multiple avoidance holes 10a may be completely consistent. In this way, it is beneficial to improve the appearance consistency of the electronic device 1000 and improve the appearance effect of the electronic device 1000. In some embodiments, the shapes and sizes of the multiple avoidance holes 10a may not be completely the same.

For example, the protective cover 20 may be located on the side of the decorative element body 10 facing away from the middle frame 310, and fixedly connected to the decorative element body 10 and/or the back cover 320. The material of the protective cover 20 may be glass, transparent plastic or other materials that allow light to pass through.

Exemplarily, the decorative element body 10 may include a metal portion. Among them, the first radiator 30 may be formed by at least a part of the metal portion. In this embodiment, the metal portion of the decorative element body 10 may be entirely used to form the first radiator 30. In some embodiments, the decorative element body 10 may also include a non-metallic portion. The non-metallic portion may be connected to the metal portion. In some embodiments, a medium may be filled between the decorative element body 10 and the middle frame 310 and/or the circuit board 400 to isolate the first radiator 30 from the middle frame 310 and/or the circuit board 400. Among them, the material of the medium may be an insulating material such as plastic.

Fig. 8 is a schematic diagram of the assembly structure of the structure shown in Fig. 6 and the camera module 600 at another viewing angle. Fig. 9 is a schematic diagram of a partial cross-sectional structure of an embodiment of the electronic device 1000 shown in Fig. 2b cut along B-B.

As shown in Figures 7 to 9, the decorative element body 10 can be located in the middle position between the first side (i.e., the first long side 3113 in this embodiment) and the second side (i.e., the second long side 3114 in this embodiment), that is, the decorative element body 10 can be centered in the length extension direction of the top side (i.e., the first short side 3111 in this embodiment). Among them, the distance between the first radiator 30 decorative element body 10 and the first side is the first distance. The distance between the decorative element body 10 and the second side is the second distance. Exemplarily, when the ratio of the first distance to the second distance is in the range of 0.8 to 1.2, the decorative element body 10 can be regarded as being located in the middle position between the first side and the second side. It should be noted that the ratio of the first distance to the second distance includes two end values of 0.8 and 1.2 in the range of 0.8 to 1.2.

Exemplarily, the first radiator 30 may include a first area 31 and a second area 32 connected. The projection of the first area 31 of the first radiator 30 on the circuit board 400 may not overlap with the projection of the camera module 600 on the circuit board 400. The projection of the second area 32 of the first radiator 30 on the circuit board 400 may overlap with the projection of the camera module 600 on the circuit board 400. For ease of understanding, FIG. 8 illustrates the outline of the portion of the camera module 600 blocked by the first radiator 30 through a wider dotted line.

Exemplarily, the first radiator 30 may include a plurality of first grounding points 33 disposed at intervals. The plurality of first grounding points 33 may all be located in the first area 31. The camera decoration assembly 100 may also include a plurality of first grounding members 61 (the first grounding members 61 are illustrated by narrow dashed lines in FIG8 ). The first radiator 30 may be coupled to the floor through a plurality of first grounding members 61 in a one-to-one correspondence at the plurality of first grounding points 33. In this embodiment, the floor may be a metal layer on the circuit board 400. In some embodiments, at least one of the plurality of first grounding points 33 may also be used to release static electricity generated on the decoration body 10. In some embodiments, the resonant frequency and the directivity pattern of the first radiator 30 may also be adjusted by adjusting the relative positions between the plurality of first grounding points 33.

Exemplarily, the first radiator 30 may include a first feeding point 34. The camera decorative assembly 100 may also include a first feed line 71 (the first feed line 71 is illustrated by a narrow dashed line in FIG. 8). The first feeding point 34 may be located in the first area 31. The first radiator 30 may be electrically connected to a first feeding terminal (not shown) of the circuit board 400 at the first feeding point 34 through the first feed line 71.

Exemplarily, the first frame radiator 510 of the electronic device 1000 can be used to work in the first frequency band. The first radiator 30 can be used to support communication in the first frequency band, that is, the first frame radiator 510 is at the same frequency as the first radiator 30. The first frame radiator 510 and the first radiator 30 can be electrically connected to the same RF chip (not shown). That is, the antenna device 500 can be electrically connected to the same RF chip through the first frame radiator 510 and the first radiator 30, so as to achieve an extended directional pattern, or an extended beam, or an extended bandwidth to improve antenna performance. It should be understood that the same RF chip in the embodiment of the present application can refer to the same receiver (receiver) or the same transceiver (transeiver), so that the first frame radiator 510 and the first radiator 30 can be used as receiving antennas with the same function, and diversity synthesis is performed by the receiver or the transceiver to achieve an improvement in antenna performance. Among them, the first frequency band can correspond to the communication frequency band of satellite messaging and/or satellite phone, for example, the receiving frequency band of satellite messaging and/or satellite phone. At this time, the first radiator 30 and the first frame radiator 510 can be electrically connected to the same satellite communication chip/RF chip.

Fig. 10 is a schematic diagram of the maximum radiation direction of the directional pattern generated by the first frame radiator 510 of a general electronic device 1000. Fig. 11 is a schematic diagram of the maximum radiation direction of the directional pattern generated by the first frame radiator 510 and the first radiator 30 of the electronic device 1000 shown in Fig. 6 .

As shown in Figures 10 and 11, the maximum radiation direction of the directional pattern generated by the first frame radiator of a general electronic device can be the direction from the bottom of the electronic device to the top. The first frame radiator can be used to work in the first frequency band. When the first frame radiator radiates, the beam generated by the first frame radiator is narrow (for example, below ±10°). In this embodiment, by setting the first radiator 30 in the camera decoration component 100, the first radiator 30 can be used to support communication in the first frequency band. The first radiator 30 is at the same frequency as the first frame radiator 510. The first radiator 30 and the first frame radiator 510 can be electrically connected to the same RF chip. In this way, the first radiator 30 and the first frame radiator 510 can be used as receiving antennas with the same function and perform diversity synthesis through the same RF chip. When the first radiator 30 and the first frame radiator 510 work at the same time, the directional pattern generated by the first radiator 30 can be complementary to the directional pattern generated by the first frame radiator 510, and the beam generated by the first radiator 30 and the first frame radiator 510 is wider (for example, above ±30°) to improve the antenna performance.

Exemplarily, the first frequency band can be applied to the communication frequency band of satellite messages and/or satellite phones. For example, the first frequency band can correspond to the receiving frequency band of satellite messages and/or satellite phones. That is, both the first radiator 30 and the first frame radiator 510 can be used to receive signals in the first frequency band. In some embodiments, the first frame radiator 510 can also work in the transmitting frequency band of satellite messages and/or satellite phones. That is, the first frame radiator 510 can be used to receive and transmit signals in the first frequency band. The first radiator 30 can be used only to receive signals in the first frequency band. In other embodiments, the first frequency band can also correspond to the receiving frequency band of satellite messages and/or satellite phones. That is, both the first radiator 30 and the first frame radiator 510 can be used to transmit signals in the first frequency band. In some other embodiments, both the first radiator 30 and the first frame radiator 510 can also be used to receive and transmit signals in the first frequency band.

It is understandable that the camera decoration assembly 100 in this embodiment may include a decoration body 10. Among them, the decoration body 10 may include a metal part. At least part of the metal part can be used to form a first radiator 30. The first radiator 30 can be used to support the communication of the first frame radiator 510 in the first frequency band, that is, the first radiator 30 can be at the same frequency as the first frame radiator 510. The first radiator 30 and the first frame radiator 510 are electrically connected to the same RF chip, so that the first radiator 30 and the first frame radiator 510 can be combined by diversity through the same RF chip to achieve the improvement of antenna performance. At the same time, the first radiator 30 is formed by the metal part of at least part of the decoration body 10, and the metal part of the decoration body 10 can achieve "one thing for multiple uses", so that the first radiator 30 can improve the antenna performance without occupying the limited antenna layout space in the frame 311 of the electronic device 1000, which is conducive to releasing the antenna layout pressure of the frame 311 of the electronic device 1000.

Secondly, the first frame radiator 510 can be arranged at the top edge, and the decorative element body 10 can be arranged in the center relative to the first side edge and the second side edge. The directional pattern of the first radiator 30 can be complementary to the directional pattern of the first frame radiator 510, and the first radiator 30 can synthesize a wide beam with the first frame radiator 510 to achieve an extended directional pattern and an extended beam, so that the radiation formed by the first radiator 30 and the first frame radiator 510 can have better transmission and reception capabilities in a wider direction.

Secondly, the first frequency band can be applied to the communication frequency band of satellite messages and/or satellite phones. It should be understood that when a user performs satellite communication, it is necessary to point the maximum radiation direction of the antenna to the satellite to achieve satellite alignment (that is, to establish a communication connection with the satellite). When the antenna beam is narrow (for example, less than ±10°), the antenna has a high requirement for satellite alignment, and the attitude change of the electronic device 1000 has a greater impact on the quality of satellite communication. When the antenna beam is wide (for example, more than ±30°), the satellite alignment requirement is low, and the attitude change of the electronic device 1000 has a small impact on the quality of satellite communication. The first radiator 30 in this embodiment can synthesize a wide beam with the first frame radiator 510, which is beneficial to reduce the satellite alignment requirement of the electronic device 1000 during satellite communication, thereby effectively reducing the impact of the attitude change of the electronic device 1000 on the quality of satellite communication, which is beneficial to improving the satellite communication performance of the electronic device 1000. Among them, the first frequency band can correspond to the receiving frequency band of satellite messages and/or satellite phones. In this way, when the user uses the electronic device 1000 to receive satellite signals, the receiving sensitivity is high, which is conducive to enhancing the ability of the electronic device 1000 to receive signals and improving the user experience. In other words, the first radiator 30 in this embodiment can form a multi-satellite antenna system with the first frame radiator 510. In this way, by setting up a multi-satellite antenna system, the user experience when using the electronic device 1000 for satellite communication can be effectively improved.

In some implementations, the first radiator 30 may not include the first feeding point 34. The first radiator 30 may also function as a parasitic branch of the antenna device 500 to generate resonance, thereby improving the antenna performance of the antenna device 500.

In some embodiments, the camera decorative assembly 100 can be arranged close to the first long side 3113 relative to the second long side 3114. The first frame radiator 510 can also be arranged on the first long side 3113. Among them, the first frequency band of the first frame radiator 510 can correspond to the communication frequency band of WIFI/Bluetooth. In this way, the first radiator 30 can be used to enhance the communication signal of WIFI/Bluetooth of the electronic device 1000 and improve the user experience.

Please refer to Figures 5 to 7 again. The camera decoration component 100 may also include a second radiator 40. The second radiator 40 may be an NFC coil. The second radiator 40 may be fixed to the surface of the first radiator 30 facing away from the screen 200 by bonding or the like. The second radiator 40 may be located between the decorative part body 10 and the protective cover plate 20. The second radiator 40 may be spaced apart from the first feeding point 34 and the plurality of first grounding points 33 of the first radiator 30. The second radiator 40 may also be spaced apart from the plurality of avoidance holes 10a of the decorative part body 10. Among them, the operating frequency band of the second radiator 40 may be 13.5 MHz. The operating frequency band of the second radiator 40 may be much lower than the first frequency band. For example, the center frequency of the first frequency band may be greater than 100 times the center frequency of the operating frequency band of the second radiator 40. In other embodiments, the second radiator 40 may also be a wireless charging coil.

Exemplarily, the second radiator 40 may include a second feeding point 41. The second feeding point 41 may be electrically connected to a second feeding terminal (not shown) on the circuit board 400 at the second feeding point 41. The second radiator 40 may be electrically connected to the second feeding terminal on the circuit board 400 at the second feeding point 41 by bypassing the decorative element body 10 through an electrical connection such as a lead. In other embodiments, the decorative element body 10 may also be provided with a connecting hole. The second radiator 40 may also be electrically connected to the second feeding terminal on the circuit board 400 at the second feeding point 41 through an electrical connection such as a lead through the connecting hole on the decorative element body 10.

Exemplarily, the camera decorative component 100 may also include an inductor structure (not shown). The inductor structure may be connected in series to the second feeding point 41 of the second radiator 40. Among them, the inductor structure may include one or more inductors. Exemplarily, the inductance of the inductor structure may be greater than 60 millihenries. In this way, by connecting the inductor structure in series to the second feeding point 41, the inductor structure may serve as a low-pass filter to cut off the high-frequency signal input to the second radiator 40, thereby avoiding the influence of clutter.

Exemplarily, the camera decoration component 100 may further include an isolation layer (not shown). The isolation layer may be fixed between the first radiator 30 and the second radiator 40. The material of the isolation layer may be ferrite or nanocrystal. In this way, the isolation layer may exhibit magnetic conductor properties at low frequencies (for example, at the operating frequency band of the second radiator 40), and the isolation layer may exhibit electrical conductor properties with low conductivity at high frequencies (for example, at the first frequency band) to avoid resonance between the second radiator 40 and the first radiator 30, and the isolation between the second radiator 40 and the first radiator 30 is better.

It is understandable that the camera decoration assembly 100 in this embodiment may include a first radiator 30 and a second radiator 40. The first radiator 30 may be composed of a metal portion of at least part of the decoration body 10. The second radiator 40 may be an NFC coil or a wireless charging coil. The second radiator 40 may be fixedly connected to the surface of the first radiator 30. In this way, the second radiator 40 may be arranged close to the first radiator 30, and the two may reuse the space of the camera decoration assembly 100, thereby improving the antenna performance without occupying the limited antenna layout space in the frame 311 of the electronic device 1000, which is conducive to releasing the antenna layout pressure of the frame 311 of the electronic device 1000.

FIG. 12 is a schematic diagram of an enlarged structure of the structure shown in FIG. 6 at position C. FIG.

As shown in Figures 9 and 12, the camera decoration assembly 100 may also include a third radiator 50 (the third radiator 50 is also illustrated in Figures 5 and 6). The first radiator 30 may be provided with a groove 35. The third radiator 50 may be at least partially disposed in the groove 35. The third radiator 50 may be an LDS antenna radiator or an FPC antenna radiator. The camera decoration assembly 100 may also include a bracket (not shown). The third radiator 50 may be fixed in the groove 35 of the first radiator 30 by a bracket. The third radiator 50 may be suspended relative to the bottom wall 351 of the groove 35. Among them, the bracket may be an insulator for supporting the third radiator 50. For example, the bracket may be a plastic bracket. The third radiator 50 may be arranged (for example, printed/printed) on the upper surface or lower surface of the bracket. Exemplarily, the height of the third radiator 50 may be less than or equal to the depth of the groove 35. The height of the third radiator 50 may be the distance between the upper surface of the third radiator 50 (ie, the surface of the third radiator 50 facing the opening of the groove 35 ) and the bottom wall 351 of the groove 35 .

Exemplarily, the third radiator 50 may be a sheet radiator. In one embodiment, the length of the third radiator 50 may be less than 5 times the width of the third radiator 50. That is, the ratio of the length to the width of the third radiator 50 may be less than 5. In one embodiment, when the shape of the third radiator 50 is irregular, the length and width of the third radiator 50 may be the length and width of the rectangle surrounded by the outer contour of the third radiator 50. At this time, the ratio of the area of the third radiator 50 itself to the area of the rectangle surrounded by the outer contour of the third radiator 50 may be greater than 1. For ease of explanation, the length direction of the third radiator 50 is defined as the first direction, and the width direction of the third radiator 50 is defined as the second direction. In this embodiment, the first direction may be parallel to the X-axis direction. The second direction may be parallel to the Y-axis direction.

Exemplarily, the third radiator 50 may include a first end 51 and a second end 52. The first end 51 of the third radiator 50 may be a third grounding point 53 provided on the third radiator 50, or a grounded portion of the third radiator 50. The camera decoration assembly 100 may further include a second grounding member 72. The third radiator 50 may be electrically connected to the first radiator 30 at the third grounding point 53 through the second grounding member 72. At this time, the first radiator 30 may serve as a reference ground for the third radiator 50. It should be understood that since the size of the third radiator 50 is smaller than that of the first radiator 30, the fundamental mode frequency band of the third radiator 50 may be higher than the fundamental mode frequency band of the first radiator 30, so that the first radiator 30 may be regarded as a reference ground for the third radiator 50. The second end 52 of the third radiator 50 is not grounded. The first end 51 of the third radiator 50 may be a grounding end, and the second end 52 of the third radiator 50 may be an open end. The current of the third radiator 50 may flow into the first radiator 30 through the first grounding point 33. For example, the first end 51 and the second end 52 may be arranged in the first direction. The number of the third grounding points 53 may be multiple (eg, three). The multiple third grounding points 53 may be arranged at intervals along the second direction.

Exemplarily, the third radiator 50 may include a third feeding point 54. The third feeding point 54 may be located between two adjacent third grounding points 53. The bottom wall 351 of the groove 35 of the first radiator 30 may also be provided with a through hole 352. The camera decoration component 100 may also include a second feed line 62. The third radiator 50 may be electrically connected to the feeding point end of the circuit board 400 at the third feeding point 54 through the second feed line 62. Among them, the second feed line 62 may pass through the through hole 352 of the first radiator 30.

In some embodiments, the camera decoration assembly 100 may further include a feeder grounding member 73. One end of the feeder grounding member 73 may be electrically connected to the first radiator 30, and the other end of the feeder grounding member 73 may be electrically connected to the floor. A portion of the feeder grounding member 73 may be located in the through hole 352. In this way, the impedance of the third feeding point 54 of the third radiator 50 may be adjusted by the feeder grounding member 73 to improve the antenna performance. In one embodiment, the feeder grounding member 73 may be a hollow structure. The second feeder 62 may be inserted into the feeder grounding member 73. The feeder grounding member 73 may wrap a portion of the second feeder 62. The second feeder 62 and the feeder grounding member 73 may be coaxial structures. At this time, the second feeder 62 may be equivalent to the inner core of the coaxial structure, and the feeder grounding member 73 may be equivalent to the outer core of the coaxial structure. In another embodiment, the feeder grounding member 73 may be a solid structure. The feeder grounding member 73 may be located on one side of the second feeder 62.

13 is a schematic diagram of S11 simulation curves of the first radiator 30 and the third radiator 50 shown in FIG6 . It should be noted that curve 1 in FIG13 is the S11 simulation curve of the first radiator 30 , and curve 2 is the S11 simulation curve of the third radiator 50 .

As shown in FIG. 13 , the first radiator 30 can generate multiple resonances based on the fundamental mode and the higher-order mode. Among them, the resonance generated by the first radiator 30 based on the fundamental mode is the first resonance. The first radiator 30 can operate in multiple resonance frequency bands. The third radiator 50 can generate a resonance based on the fundamental mode, that is, the second resonance. The frequency band of the first resonance can be lower than the frequency band of the second resonance.

It is understandable that the camera decoration assembly 100 in this embodiment may further include a third radiator 50, and the third radiator 50 may be at least partially disposed in the groove 35 of the first radiator 30. In this way, the first radiator 30 and the third radiator 50 may reuse the space of the camera decoration assembly 100, thereby improving the antenna performance without occupying the limited antenna layout space in the frame 311 of the electronic device 1000, which is conducive to releasing the antenna layout pressure of the frame 311 of the electronic device 1000.

Fig. 14 is a schematic diagram of the structure of another embodiment of the camera decoration assembly 100 shown in Fig. 12. Fig. 15 is a schematic diagram of the S11 simulation curve of the third radiator 50 and the fourth radiator 80 shown in Fig. 14.

As shown in Figures 14 and 15, the structure of the camera decoration assembly 100 in this embodiment is substantially the same as the structure of the camera decoration assembly 100 shown in Figure 12, and the same parts are not repeated. The differences between the two will be described below. Exemplarily, the first end 51 of the third radiator 50 may be provided with a third grounding point 53. The camera decoration assembly 100 may also include a fourth radiator 80. The fourth radiator 80 may be an LDS antenna radiator or an FPC antenna radiator. The fourth radiator 80 may be fixed in the groove 35 of the first radiator 30 by a bracket, and is spaced apart from the third radiator 50. The fourth radiator 80 may be at least partially accommodated in the groove 35. The fourth radiator 80 may be suspended relative to the bottom wall 351 of the groove 35. Exemplarily, the fourth radiator 80 may be a sheet radiator. The shape and size of the fourth radiator 80 may be the same as the shape and size of the third radiator 50.

Exemplarily, the fourth radiator 80 may include a first end 81 and a second end 82. The first end 81 of the fourth radiator 80 may be a fourth grounding point 83 set on the fourth radiator 80, or a grounded portion of the fourth radiator 80. The camera decoration assembly 100 may further include a third grounding member 74. The fourth radiator 80 may be electrically connected to the first radiator 30 at the fourth grounding point 83 through the third grounding member 74. At this time, the first radiator 30 may also serve as a reference ground for the fourth radiator 80. The second end 82 of the fourth radiator 80 is not grounded. The first end 81 of the fourth radiator 80 is a grounding end, and the second end 82 of the fourth radiator 80 is an open end. Among them, the first end 81 of the fourth radiator 80 may be arranged opposite to the second end 52 of the third radiator 50. The second end 82 of the fourth radiator 80 may be arranged opposite to the first end 51 of the third radiator 50. That is, the grounding end of the fourth radiator 80 may be arranged opposite to the open end of the third radiator 50. The open end of the fourth radiator 80 may be disposed opposite to the ground end of the third radiator 50 .

Exemplarily, the fourth radiator 80 can generate related resonance by coupling the energy of the third radiator 50. At this time, the third radiator 50 and the fourth radiator 80 can form a composite antenna and operate in two continuous resonant frequency bands to achieve broadband coverage. It should be understood that when the ratio between the two frequencies corresponding to the two resonant points is in the range of 1:1 to 1:1.2, the two resonant frequency bands where the two resonant points are located can be regarded as continuous. Among them, the third radiator 50 can be used as a main radiator. The fourth radiator 80 can be used as a parasitic radiator.

It can be understood that in this embodiment, a composite antenna is formed by arranging a fourth radiator 80 and a third radiator 50 in the groove 35. Among them, the third radiator 50 can be used as a main radiator, and the fourth radiator 80 can be used as a parasitic radiator. In this way, the composite antenna formed by the third radiator 50 and the fourth radiator 80 can generate two resonant frequency bands, and the two resonant frequency bands are continuous, which is conducive to broadening the bandwidth of the composite antenna and improving the antenna performance. At the same time, the fourth radiator 80 can reuse the space of the camera decoration component 100, so that the antenna performance can be improved without occupying the limited antenna layout space in the frame 311 of the electronic device 1000, which is conducive to releasing the antenna layout pressure of the frame 311 of the electronic device 1000.

Fig. 16 is a schematic diagram of the structure of Fig. 12 in another embodiment. Fig. 17 is a schematic diagram of the S11 simulation curve of the third radiator 50 shown in Fig. 16. It should be noted that curve 1 in Fig. 17 is an S11 simulation curve of the radiation generated by the first current on the third radiator 50, and curve 2 is an S11 simulation curve of the radiation generated by the second current on the third radiator 50.

As shown in Figures 16 and 17, the structure of the camera decoration assembly 100 in this embodiment is substantially the same as the structure of the camera decoration assembly 100 shown in Figure 12, and the same parts are not repeated. The differences between the two will be described below. Exemplarily, the third radiator 50 may also include a fourth feeding point 55. The third radiator 50 may include a third end 56 and a fourth end 57. The third end 56 and the fourth end 57 may be arranged in the second direction. The third feeding point 54 may be located at the first end 51 of the third radiator 50 and arranged near the third end 56. For example, the first third feeding point 54 may be located at a corner position between the first end 51 and the third end 56. The fourth feeding point 55 may be located at the first end 51 and between the third end 56 and the fourth end 57. For example, the fourth feeding point 55 may be located at an intermediate position between the third end 56 and the fourth end 57. That is, the distance from the fourth feeding point 55 to the third end 56 may be equal to the distance from the fourth feeding point 55 to the fourth end 57.

Exemplarily, the number of through holes 352 of the groove 35 may be two. The number of second feed lines 62 may also be two. One of the feed lines 62 may pass through one of the through holes 352 and respectively connect the third feeding point 54 and the third feeding terminal (not shown) of the circuit board 400. Another feed line 62 may pass through another through hole 352 and respectively connect the fourth feeding point 55 and the fourth feeding terminal (not shown) of the circuit board 400 (please refer to FIG. 9 ).

Exemplarily, the number of the third grounding points 53 of the third radiator 50 may be two. One of the third grounding points 53 may be located between the third feeding point 54 and the fourth feeding point 55. The other third grounding point 53 may be located on a side of the fourth feeding point 55 facing away from the third feeding point 54.

Exemplarily, when the third radiator 50 is working, the third feed point 54 can excite a first current along a first direction on the third radiator 50, and the fourth feed point 55 can excite a second current along a second direction on the third radiator 50. The first current can be orthogonal to the second current. That is, the third feed point 54 and the fourth feed point 55 can respectively excite a transverse mode and a longitudinal mode on the third radiator 50. The third radiator 50 can be expanded into a dual-antenna structure of a common radiator by the excitation of the transverse and longitudinal modes, and operate in two resonant frequency bands. The isolation between the two antennas of the common radiator is relatively high (for example, the isolation is below 15). In one embodiment, one of the resonant frequency bands can cover the N77 frequency band (3.3GHz-4.2GHz). Another resonant frequency band can cover the WIFI 5G frequency band (5.15GHz-5.875GHz).

It can be understood that the third radiator 50 in this embodiment includes a third feeding point 54 and a fourth feeding point 55. The third feeding point 54 and the fourth feeding point 55 can both be located at the first end 51 of the third radiator 50. Among them, the third feeding point 54 can be arranged close to the third end 56. The fourth feeding point 55 can be located between the third end 56 and the fourth end 57. In this way, the third feeding point 54 and the fourth feeding point 55 can respectively excite a first current along a first direction and a second current along a second direction on the third radiator 50. The first current is orthogonal to the second current. That is, the third feeding point 54 and the fourth feeding point 55 can respectively excite a transverse mode and a longitudinal mode on the third radiator 50. The third radiator 50 can be expanded into a dual antenna structure of a common radiator by the excitation of the transverse and longitudinal modes to improve the antenna performance of the electronic device 1000.

In some embodiments, the second end 52 of the third radiator 50 may also be provided with at least one notch 58. The notch 58 may be substantially in the shape of a long strip. Thus, by providing the notch 58 at the second end 52, the electrical length of the third radiator 50 in the first direction may be increased, so that the third radiator 50 may support resonance in a lower frequency band, which is beneficial to improving antenna performance.

In other embodiments, the camera decoration assembly 100 may also include only the first radiator 30 and the second radiator 40 , or the camera decoration assembly 100 may also include only the first radiator 30 and the third radiator 50 .
