In this embodiment, the shapes of the first sub-radiator 11 and the second sub-radiator 12 are both straight lines for description. Of course, in other embodiments, the shape of the first sub-radiator 11 and the second sub-radiator 12 may also be a bent strip shape or other shapes.

Referring to FIG. 3 , the first sub-radiator 11 includes a free end 111 and a first coupling end 112 . In this embodiment, the free end 111 and the first coupling end 112 are opposite ends of the linear first sub-radiator 11 . In other embodiments, the first sub-radiator 11 is in a bent shape, and the free end 111 and the first coupling end 112 may not face each other along a straight line, but the free end 111 and the first coupling end 112 may not face each other in a straight line. The ends 112 are the two ends of the first sub-radiator 11 . The first sub-radiator 11 also has a ground point A and a feed point B located between the free end 111 and the first coupling end 112 .

The first sub-radiator 11 and the second sub-radiator 12 may be arranged along a straight line or substantially along a straight line (that is, with a smaller tolerance in the design process). Of course, in other embodiments, the first sub-radiator 11 and the second sub-radiator 12 can also be staggered in the extension direction to form an avoidance space.

Referring to FIG. 3 , the first coupling end 112 and the second coupling end 121 are opposite and spaced apart. A coupling gap 13 is formed between the first coupling end 112 and the second coupling end 121 . The coupling gap 13 is a gap between the first coupling end 112 of the first sub-radiator 11 and the second coupling end 121 of the second sub-radiator 12, for example, The width of the coupling gap 13 is 0.5 mm to 2 mm, but is not limited to this size.

Referring to FIG. 4 , the radiator 10 generates multiple resonance modes (such as a, b, c in FIG. 4 ) under the excitation of the signal source 21 . The resonance mode is characterized by the fact that the antenna assembly 100 has high electromagnetic wave transmitting and receiving efficiency at and near the resonant frequency. In this application, the radiator 10 has high electromagnetic wave transmission and reception efficiency at and near multiple resonant frequencies under the excitation of the signal source 21, and can thus support the transmission and reception of electromagnetic wave signals in multiple frequency bands.

This application does not specifically limit the shapes and structures of the first sub-radiator 11 and the second sub-radiator 12. The shapes of the first sub-radiator 11 and the second sub-radiator 12 are both Including but not limited to strips, sheets, rods, coatings, films, etc. When the first sub-radiator 11 and the second sub-radiator 12 are in strip shape, this application does not limit the extension trajectories of the first sub-radiator 11 and the second sub-radiator 12. Therefore, both the first sub-radiator 11 and the second sub-radiator 12 can extend in straight lines, curves, multi-stage bends, etc. The above-mentioned radiator 10 may be a line with a uniform width on the extension track, or may be a strip with a gradient width, a widened area, and other widths.

When the antenna assembly 100 is disposed in the electronic device 1000, the ground GND is electrically connected to the reference ground of the electronic device 1000.

As for the antenna structure, in general technology, the effective efficiency bandwidth of the antenna is not wide enough, for example, in the coverage of medium and high frequency bands (1000MHz ~ 3000MHz). For example, in the case of 1710MHz ~ 2690MHz (B3/N3+B1/N1+B7/N7), at least two resonant modes are used to cover. However, the bandwidth of these resonant modes is small and spaced apart from each other. It is difficult to cover B3/N7 at the same time. N3+B1/N1, it is also difficult to cover B1/N1+B7/N7 at the same time, and it is even more difficult to cover B3/N3+B1/N1+B7/N7 at the same time, resulting in poor signal coverage or insufficient miniaturization of the antenna in certain frequency bands. It should be noted that the above frequency bands are only examples and cannot be used as limitations on the frequency bands that can be radiated by this application.

The antenna assembly 100 provided by this application designs the structures and grounding points of the first sub-radiator 11 and the second sub-radiator 12 so that the first sub-radiator 11 and the second sub-radiator 12 are The current of the second sub-radiator 12 has a variety of distribution modes, thereby achieving a simple structure of the antenna assembly 100 while also generating a variety of resonance modes. The bandwidth of the frequency band that the multiple resonance modes can support is greater than or equal to 1G, so that The antenna assembly 100 can support a wider bandwidth, thereby improving the throughput and data transmission rate when the antenna assembly 100 is applied to the electronic device 1000. When the antenna assembly 100 is applied to the above-mentioned mid-to-high frequency band (for example, 1710MHz ~2690MHz), can support B3/N3+B1/N1+B7/N7 at the same time, so the antenna assembly 100 at least has a simple structure, miniaturization, and can be used in the application frequency band of B3/N3+B1/N1+B7/N7 It has high efficiency and data transmission rate. Among them, B3/N3 includes the situation where either B3 or N3 is selected or both exist. The definitions of B1/N1 and B7/N7 are similar to B3/N3 and will not be repeated here. Of course, the antenna assembly 100 provided in this application can also be applied to 1000MHz to 2000MHz, 3000MHz to 0MHz, etc.

Referring to FIG. 3 and FIG. 4 , the radiator 10 generates at least three resonance modes under the excitation of the signal source 21 of the radio frequency front-end unit 20 . In other words, the radiator 10 has high transceiving efficiency at at least three frequencies under the excitation of the signal source 21 . The at least three resonance modes include but are not limited to the first resonance mode a, the second resonance mode b, and the third resonance mode c. The first resonance mode a, the second resonance mode b and the third resonance mode c are all generated simultaneously. The resonant frequency of the first resonant mode a, the resonant frequency of the second resonant mode b, and the resonant frequency of the third resonant mode c are respectively the first frequency f1, the second frequency f2, and the third frequency f3. For the purpose of subsequent description, the magnitude relationship between the first frequency f1, the second frequency f2 and the third frequency f3 is that the first frequency f1, the second frequency f2 and the third frequency f3 increase in sequence. The first frequency f1, the second frequency f2 and the third frequency f3 are close to each other, so that the return loss value of the first resonance mode a, the return loss value of the second resonance mode b, and the return loss value of the third resonance mode c The value is continuous below -5dB (-5dB is only an example value and is not limited to this value). The continuous frequency bands constitute a wider bandwidth, thereby supporting multiple different frequency bands planned by multiple operators at the same time, such as B1, B3, B7, N1, N3, N 7, etc. are helpful to meet the indicators of different operators.

Referring to Figure 4, the first resonance mode a can support B3/N3, the second resonance mode b can support B1/N 1, and the third resonance mode c can support B7/N7. It can be seen from Figure 4 that the frequency band A1 supported by the first resonance mode a, the frequency band B1 supported by the second resonance mode b, and the frequency band C1 supported by the third resonance mode c are continuous and can cover a bandwidth greater than or equal to 1G. . In other words, the antenna assembly 100 of the present application can support B3/N3+B1/N1+B7/N7 at the same time.

In some possible implementations, please refer to FIG. 3 and FIG. 4 , the first sub-radiator 11 generates the first resonant mode a, the second resonant mode b and the third resonant mode c under the excitation of the signal source 21 At least two of them, the second sub-radiator 12 generates at least one of the first resonance mode a, the second resonance mode b and the third resonance mode c under the excitation of the signal source 21 .

Since the resonant frequencies of the first resonant mode a, the second resonant mode b, and the third resonant mode c increase in sequence, the effective electrical length of the radiator 10 supporting the first resonant mode a, the effective electrical length of the radiator 10 supporting the second resonant mode b, The effective electrical length of the radiator 10 and the effective electrical length of the radiator 10 supporting the third resonance mode c decrease in sequence. Since the middle part of the first sub-radiator 11 is grounded and electrically connected to the signal source 21, in other words, the ground point A and the feed point B can divide the first sub-radiator 11 so that all The first sub-radiator 11 can form multiple radiation sections with different effective electrical lengths. For example, a radiation section can be formed between the free end 111 and the first coupling end 112, and the ground point A and the third Another radiation section can be formed between one coupling end 112, and these radiation sections can cause the first sub-radiator 11 to generate multiple resonance modes.

For example, the first sub-radiator 11 is used to generate the first resonance mode a under the excitation of the signal source 21. The first sub-radiator 11 and the second sub-radiator 12 is used to generate the second resonance mode b under the excitation of the signal source 21, the first sub-radiator 11 between the ground point A and the first coupling end 112 and the The second sub-radiator 12 is used to generate the third resonance mode c under the excitation of the signal source 21 . The frequency of the third resonant mode c is relatively high, and the required electrical length of the radiator 10 is relatively short. The second sub-radiator 12 is provided to assist in generating the third resonant mode c, so that the The length of the second sub-radiator 12 is relatively short, so that the entire length of the radiator 10 is relatively small, reducing the stacked size of the antenna assembly 100 and promoting miniaturization of the antenna assembly 100 .

Please refer to Figure 4. The frequency band supported by the first resonance mode a is the first frequency band T1. The frequency band supported by the second resonance mode b is the second frequency band T2. The frequency band supported by the third resonance mode c is the third frequency band T3. The first frequency band T1, the second frequency band T2 and the third frequency band T3 are aggregated to form a target application frequency band T4. The bandwidth H of the target application frequency band T4 is greater than or equal to 1.4G. Relative bandwidth is greater than or equal to 50%. Optionally, the first frequency band T1 supported by the first resonance mode a, the second frequency band T2 supported by the second resonance mode b, and the third frequency band T3 supported by the third resonance mode c all have a return loss of -5dB. The following corresponding frequency bands. The first frequency band T1, the second frequency band T2 and the third frequency band T3 are continuous (overlapping portions are used to achieve continuity) and aggregated to form the target application frequency band T4. The difference between the maximum frequency and the minimum frequency of the target application band T4 is greater than or equal to 1.4G. It should be noted in this application that by adjusting the effective electrical length and feeding position of the radiator 10, the width of the target application frequency band T4 can also be adjusted to 1.8G, 2G, 2.5G, 3G, etc.

From the perspective of the current side, the antenna assembly 100 generates at least three current distributions under the excitation of the signal source 21 , including a first current distribution R1 , a second current distribution R2 and a third current distribution R3 respectively.

Please refer to Figures 7 and 8. The current distribution corresponding to the first resonant mode a includes but is not limited to the first current distribution R1: flowing from the first coupling end 112 to the ground point A and from the free end 111 to The ground point A. Specifically, a part of the current flows from the first coupling end 112 to the ground point A, and another part of the current flows from the free end 111 to the ground point A, wherein the two parts of the current flow in opposite directions. In the first resonance mode a, a small amount of current is also generated by the coupling between the second sub-radiator 12 and the first sub-radiator 11, and the current flows from the ground terminal 122 to the second coupling terminal. 121. The above current distribution generates the first resonance mode a.

Referring to FIG. 9 and FIG. 10 , the current distribution corresponding to the second resonance mode b includes but is not limited to the second current distribution R2: flowing from the ground terminal 122 to the ground point A and flowing to the free end 111 . Specifically, the current on the first sub-radiator 11 flows from the first coupling end 112 to the free end 111, and the second sub-radiator 12 is coupled by the first sub-radiator 11. A current is generated, and the current flows from the ground terminal 122 to the second coupling terminal 121 . In other words, the current of the first sub-radiator 11 and the current of the second sub-radiator 12 flow in the same direction.

9 and 10 , the second current distribution R2 includes a first sub-current distribution R21 and a second sub-current distribution R22. Wherein, the first sub-current distribution R21 is the current distribution on the first sub-radiator 11 to generate the first sub-resonant mode b1; the second sub-current distribution R22 is the current distribution on the second sub-radiator 12 , to generate the second sub-resonant mode b2. The first sub-resonant mode b1 and the second sub-resonant mode b2 together form a second resonant mode b. In other words, the second resonance mode b includes the first sub-resonance mode b1 and the second sub-resonance mode b2. The first sub-resonance mode b1 is generated by the first sub-radiator 11 under the excitation of the signal source 21 . The second sub-resonant mode b2 is generated by the second sub-radiator 12 under the capacitive coupling of the first sub-radiator 11 . Optionally, the first sub-resonant mode b1 is a dipole mode, and the second sub-resonant mode b2 is a parasitic radiation mode generated by the second sub-radiator 12 . In this way, since the current of the first sub-radiator 11 and the current of the second sub-radiator 12 flow in the same direction, the parasitic radiation mode and the dipole mode can enhance each other to produce strong radiation efficiency. In other words, since the second resonant mode b essentially has the aggregation of two sub-resonant modes, the resonant frequencies of the two resonant modes are close to each other, thereby forming a resonant mode to enhance the radiation efficiency and bandwidth.

Please refer to Figure 11 and Figure 12. The current distribution corresponding to the third resonance mode c includes but is not limited to the third current distribution R3: flowing from the first coupling terminal 112 to the ground point A and from the second coupling terminal 121 flows to ground 122. The current of the first coupling terminal 112 flows to the ground point A and returns to ground, and the current of the second coupling terminal 121 flows to the ground terminal 122 and returns to ground. In other words, the current of the first sub-radiator 11 and the current of the second sub-radiator 12 flow in opposite directions. Between the first coupling end 112 of the first sub-radiator 11 and the ground point A, and between the second coupling end 121 of the second sub-radiator 12 and the ground end 122, the signal Under the action of source 21, the third resonance mode c is jointly generated.

It can be understood that from the current distribution of the first resonant mode a, the second resonant mode b and the third resonant mode c, the currents corresponding to the first resonant mode a, the second resonant mode b and the third resonant mode c have partial The same flow direction, for example, the flow direction from the first coupling end 112 to the ground point A, so that the three resonance modes can enhance each other.

In this application, please refer to Figure 4. The target application frequency band T4 formed by the aggregation of the first frequency band T1, the second frequency band T2 and the third frequency band T3 includes but is not limited to 1.6GHz~3GHz, 2GHz~3.4GHz, and 2.6GHz~4GHz. 3.6GHz~5GHz, etc. Of course, when the bandwidth of the target application frequency band T4 is 2G, 3G, etc., the target application frequency band T4 formed by the aggregation of the first frequency band T1, the second frequency band T2 and the third frequency band T3 includes but is not limited to 1GHz~3GHz, 2GHz~4GHz, 3GHz~6GHz, etc. No more examples will be given here. In this embodiment, the target application frequency band T4 formed by the aggregation of the first frequency band T1, the second frequency band T2 and the third frequency band T3 covers 1.6GHz to 3GHz.

Optionally, the target application frequency band T4 can support any one of the LTE 4G frequency band and the NR 5G frequency band or both at the same time. Wherein, when the target application frequency band T4 formed by the aggregation of the first frequency band T1, the second frequency band T2 and the third frequency band T3 covers 1.6GHz to 3GHz, the frequency bands supported by the antenna assembly 100 for the LTE 4G frequency band include but are not limited to B1 and B2 , B3, B4, B7, B32, B38, B39, B40, B41, B48, and B66.

The antenna assembly 100 provided by this application can cover any combination of the above-mentioned NR 5G frequency band and LTE 4G frequency band. Of course, the antenna assembly 100 can load LTE 4G signals alone, or load 5G NR signals alone, or it can also load LTE 4G signals and 5G NR signals at the same time, that is, dual connectivity of the 4G wireless access network and 5G-NR (LTE NR Double Connect, EN-DC).

The frequency band transmitted and received by the antenna assembly 100 provided in this implementation includes multiple carriers (carriers are radio waves of specific frequencies) aggregated, that is, carrier aggregation (CA) is implemented to increase transmission bandwidth and improve throughput. Improve signal transmission rate.

The frequency bands listed above may be medium and high frequency bands that are applied by multiple operators. The antenna assembly 100 provided by this application can simultaneously support any one or a combination of the above frequency bands, so that the antenna assembly 100 provided by this application can 100 can support the electronic device 1000 models corresponding to multiple different operators, without the need to adopt different antenna structures for different operators, further improving the application range and compatibility of the antenna assembly 100.

From the perspective of the structure of the antenna assembly 100, please refer to FIG. 7, FIG. 9 and FIG. 11. The ground point A of the first sub-radiator 11 is located between the free end 111 and the first coupling end 112. time, so that the first sub-radiator 11 and the signal source 21 form a similar “T”-shaped antenna. The “T”-shaped antenna can form the first current distribution R1 and the first sub-current distribution R21, so as to The first sub-radiator 11 is caused to generate multiple resonance modes in the mid-to-high frequency band (not limited to the mid-to-high frequency band). For example, the above-mentioned first resonant mode a and the first sub-resonant mode b1, and the resonant frequencies of the first resonant mode a and the first sub-resonant mode b1 are close, thus forming a wider bandwidth. Further, the second sub-radiator 12 is coupled with the first sub-radiator 11 to generate a second sub-current distribution R22 on the second sub-radiator 12, so that the first sub-current distribution R21 and the second sub-current distribution R22 jointly generate the second resonance mode b. A third current distribution R3 is also generated on the first sub-radiator 11 and the second sub-radiator 12, thereby generating a third resonance mode c. By setting the lengths of the first sub-radiator 11 and the second sub-radiator 12, the resonant frequencies of the first resonant mode a, the second resonant mode b, and the third resonant mode c are all similar to form a relatively wide bandwidth.

Optionally, the wavelength corresponding to the resonant frequency of the first resonant mode a is the first wavelength. The length of the radiator 10 between the free end 111 and the first coupling end 112 is (1/4) to (3/4) times the first wavelength. Wherein, when no other matching circuit is provided except the first matching circuit M1, the length of the radiator 10 between the free end 111 and the first coupling end 112 is 1/2 of the first wavelength. times to create conditions for the subsequent antenna assembly 100 to generate higher signal transceiving efficiency at the first frequency f1 and the second frequency f2. Of course, in the case where a matching circuit is provided in addition to the first matching circuit M1, the connected matching circuit can adjust the effective electrical length of the first sub-radiator 11. For example, a capacitive matching circuit can be connected such that The length of the radiator 10 between the free end 111 and the first coupling end 112 is reduced, and an inductive matching circuit is connected, so that the length between the free end 111 and the first coupling end 112 can be reduced. The length of the radiator 10 is increased, and the length of the radiator 10 between the free end 111 and the first coupling end 112 is adjusted to (1/4) times to (3) of the first wavelength. /4 times. Of course, in actual application, the length of the radiator 10 between the free end 111 and the first coupling end 112 is adjusted to (1/5) times, (4/5) times, etc. of the first wavelength. wait.

For example, when the target application frequency covers B3/N3+B1/N1+B7/N7, the range of the first frequency f1 includes but is not limited to (1.71GHz-1.88GHz). In this embodiment, the first frequency f1 For example, f1 is 1.72 GHz. In this way, the length range of the first sub-radiator 11 can be determined. Of course, the first frequency f1 may change as the frequency band covered by the target application frequency changes.

This application does not limit the specific location of the grounding point A. Optionally, the length of the radiator 10 between the ground point A and the free end 111 is (1/8) to (3/4) times the length of the first sub-radiator 11 .

In other words, the position of the ground point A may be within the range of (1/8) to (3/4) from the free end 111 on the first sub-radiator 11 . Through the above design or in combination with the design of the matching circuit on the first sub-radiator 11 (detailed description will be given later), the first sub-radiator 11 can form the first current distribution R1, the first sub-current distribution R21, etc. The current distribution generates the first resonance mode a, the first sub-resonance mode b1 and assists in generating the third resonance mode c, thereby generating a wider bandwidth and improving the throughput and data transmission rate. In addition, the grounding point A has a larger range of installation locations, and the optional range of the ground connector locations is larger. When the antenna assembly 100 is installed on the electronic device 1000, the optional range of locations of the ground connectors is larger. This makes the range of optional positions of the antenna assembly 100 larger, which is more conducive to the installation of the antenna assembly 100 in the electronic device 1000 .

Of course, 1/8 and 3/4 are just examples and are not limited thereto. In other embodiments, the length of the radiator 10 between the ground point A and the free end 111 can be slightly smaller than the length of the first sub-radiator 11 1/8, or slightly larger than 3/4 of the length of the first sub-radiator 11.

Optionally, the length of the radiator 10 between the ground point A and the free end 111 can also be (1/4) to (3/4) times the length of the first sub-radiator 11 . In other words, the position of the ground point A may be within the range of (1/4) to (3/4) from the free end 111 on the first sub-radiator 11 . Through the above design, the position of the ground point A is closer to the middle part of the first sub-radiator 11, which is beneficial to increasing the bandwidth and efficiency of the antenna assembly 100.

Optionally, the length of the radiator 10 between the ground point A and the free end 111 is (3/8) to (5/8) times the length of the first sub-radiator 11 . In other words, the position of the ground point A may be within the range of (3/8) to (5/8) from the free end 111 on the first sub-radiator 11 . Through the above design, the position of the ground point A is closer to the middle part of the first sub-radiator 11, which is beneficial to increasing the bandwidth and efficiency of the antenna assembly 100.

For example, the ground point A may be close to the middle part of the first sub-radiator 11 . Furthermore, the length between the ground point A and the free end 111 can be slightly longer than the length between the ground point A and the first coupling end 121. For example, the length between the ground point A and the free end 111 is about 18 mm. A and the first coupling end 121 are about 16 mm.

As an example, the length of the radiator 10 between the free end 111 and the first coupling end 112 is (1/2) times the first wavelength. The length of the radiator 10 between the ground point A and the free end 111 is 1/2 times the length of the first sub-radiator 11. At this time, the ground point A and the free end 111 The length of the radiator 10 between them is (1/4) times the first wavelength.

Further, by arranging a capacitive matching circuit between the ground point A and the free end 111 , the first sub-radiator 11 between the ground point A and the free end 111 can be reduced. The length of the radiator 10 between the ground point A and the free end 111 is 1/4 times the length of the first sub-radiator 11. In practical applications, it is of course not limited to this. It can also be 1/5, 2/5, etc. By arranging a grounded capacitive matching circuit between the ground point A and the first coupling terminal 112 , the first sub-circuit between the ground point A and the first coupling terminal 112 can be reduced. The length of the radiator 11, and thus the length of the radiator 10 between the ground point A and the free end 111 is 3/4 times the length of the first sub-radiator 11. In practical applications, of course, it is not Limited to this, it can also be 3/5, 4/5, etc. Correspondingly, the length of the radiator 10 between the ground point A and the free end 111 is (1/8) to (3/8) times the first wavelength.

Optionally, the capacitive matching circuit includes a capacitor, and the capacitor of the capacitive matching circuit is directly electrically connected to the first sub-radiator 11, so that the capacitor of the capacitive matching circuit can also be used as a part of the first filter 30 (for example, in subsequent The first sub-filter 31) realizes the multi-purpose use of the device, reduces the number of devices and the space they occupy, and improves the integration of the devices.

The wavelength corresponding to the resonance frequency of the third resonance mode c is the second wavelength. The length of the radiator 10 between the second coupling end 121 and the ground end 122 is (1/8) to (3/8) times the second wavelength. In other words, the length of the second sub-radiator 12 is (1/8) to (3/8) times the wavelength corresponding to the third frequency f3. When no matching circuit is provided on the second sub-radiator 12, the length of the second sub-radiator 12 is (1/4) times the wavelength corresponding to the third frequency f3, so that the second sub-radiator 12 The body 12 generates higher transceiver efficiency at the third frequency f3, and then resonates at the third frequency f3 to form a third resonance mode c. When a capacitive matching circuit is provided on the second sub-radiator 12, the length of the second sub-radiator 12 may be 1/8 times the wavelength corresponding to the third frequency f3. When an inductive matching circuit is provided on the second sub-radiator 12, the length of the second sub-radiator 12 may be 3/8 times the wavelength corresponding to the third frequency f3.

For example, when the target application frequency covers B3/N3+B1/N1+B7/N7, the range of the third frequency f3 includes but is not limited to (2.5GHz-3GHz). In this embodiment, the third frequency f3 Taking 2.76 GHz as an example, in this way, the length range of the second sub-radiator 12 can be determined. Of course, the third frequency f3 may change as the frequency band covered by the target application frequency changes.

Further, by adjusting the length of the first sub-radiator 11, the length of the second sub-radiator 12, the position of the feed point B, and the position of the ground point A, the second frequency f2 can be adjusted position, so that the first frequency f1, the second frequency f2, and the third frequency f3 are close to each other and can support a wider bandwidth.

In summary, it can be seen that the structure of the antenna assembly 100 is designed in this application so that the radiator 10 of the antenna assembly 100 includes the first sub-radiator 11 and the second sub-radiator 12, where , the ground point A of the first sub-radiator 11 is located between two ends of the first sub-radiator 11 , and the second sub-radiator 12 is the parasitic radiation of the first sub-radiator 11 The first sub-radiator 11 is similar to the radiator of a “T”-shaped antenna. In this way, the first sub-radiator 11 generates at least two resonant modes. The second sub-radiator 12 can enhance the resonance mode of the second sub-radiator 12. In this way, the first sub-radiator 11 can generate the first resonance mode a, and the first sub-radiator 11 interacts with the first resonance mode a. The second sub-radiator 12 can jointly generate the second resonance mode b. By designing and optimizing the length of the first sub-radiator 11 and the position of the ground point A, the resonance of the first resonance mode a can be achieved. The frequency is close to the resonant frequency of the second resonant mode b to form a larger bandwidth and cover the frequency band that needs to be covered. Since a part of the first sub-radiator 11 and a part of the second sub-radiator 12 form an antenna structure with both ends back to the ground, in this way, the first sub-radiator 11 and the second sub-radiator 12 To generate the third resonant mode c, the length of the second sub-radiator 12 is designed and optimized so that the resonant frequency of the third resonant mode c is close to the resonant frequency of the third resonant mode c, and the first The resonant frequencies of the resonant mode a, the second resonant mode b, and the third resonant mode c are continuous and form a bandwidth greater than or equal to 1G bandwidth, thereby improving the throughput of the antenna assembly 100 and increasing the Internet access rate of the electronic device 1000 .

Please refer to Figure 13. Figure 13 shows the efficiency of the antenna assembly 100 provided by this application in an ultimate full-screen environment. The dotted line in FIG. 13 is the radiation efficiency curve of the antenna assembly 100. The solid line is the matching total efficiency curve of the antenna assembly 100 . In this application, the display screen 200 and the metal alloy in the middle frame 420 are used as the ground electrode GND. The distance between the radiator 10 of the antenna assembly 100 and the ground electrode GND is less than or equal to 0.5 mm. , in other words, the clearance area of the antenna assembly 100 is 0.5 mm, which fully meets the environmental requirements of the electronic devices 1000 such as current mobile phones. It can be seen from Figure 13 that even in a very small headroom area, the antenna assembly 100 maintains high efficiency between 1.7GHz and 2.7GHz. For example, the efficiency of the antenna assembly 100 between 1.7GHz and 2.7GHz is greater than or equal to -5dB.

It can be seen from the above that the antenna assembly 100 provided by the present application still has high radiation efficiency in a very small clearance area. If the antenna assembly 100 is used in the electronic device 1000 and has a smaller clearance area, it will be relatively Compared with other antennas that require a larger clearance area to have higher efficiency, the overall volume of the electronic device 1000 can be reduced.

The capacitor C2 and the second inductor L2 are connected in series to form the second unit 102, and the first unit 101 and the second unit 102 are connected in parallel.

The above is an example of the specific structure of the antenna assembly 100 . In some embodiments, the antenna assembly 100 is provided in the electronic device 1000 . The following is an example of an implementation in which the antenna assembly 100 is provided in the electronic device 1000 through implementation. For the electronic device 1000 , the antenna component 100 is at least partially integrated on the housing 200 or entirely disposed within the housing 200 . The radiator 10 of the antenna assembly 100 is provided on or in the housing 200 .

The above is the basic structure of the antenna assembly 100. The antenna assembly 100 is further optimized through the following embodiments to further reduce the stack size of the antenna assembly 100.

Optionally, please refer to Figure 22. The first matching circuit M1 includes a first sub-circuit M11. One end of the first sub-circuit M11 is electrically connected to the feed point B. The other end of the first sub-circuit M11 is electrically connected to the ground. The first sub-circuit M11 is capacitive when working in the fourth frequency band. The fourth frequency band is located in the frequency band corresponding to the first resonance mode a, the second resonance mode b, and the third resonance mode c. For example, the fourth frequency band may be a continuous frequency band formed by the first resonance mode a, the second resonance mode b, and the third resonance mode c. When the first sub-circuit M11 is capacitive when operating in the fourth frequency band, the resonant frequencies of the first resonant mode a, the second resonant mode b, and the third resonant mode c can be moved toward the low-frequency end. The first sub-circuit M11 is similar to The first sub-radiator 11 between the ground point A and the first coupling end 112 is "connected with an effective electrical length", so when the frequency position required to resonate remains unchanged, it can be relatively Reduce the actual length of the first sub-radiator 11 between the ground point A and the first coupling end 112 . In this way, the first sub-radiator 11 is miniaturized.

Optionally, the first sub-circuit M11 includes but is not limited to a capacitor, a series or parallel circuit containing a capacitor, an inductor, a resistor, etc.

Optionally, when the first sub-circuit M11 includes a capacitor directly electrically connected to the first sub-radiator 11, the current can also be used as a part of the first filter 30 to realize other connections between the first sub-radiator 11 and the first sub-circuit M11. Partial isolation of the induction signal reduces the impact of the induction signal on the radio frequency signal transmitted by the first sub-circuit M11.

Referring to FIG. 23 , the first sub-radiator 11 also has a first matching point C located between the free end 111 and the ground point A. The antenna assembly 100 further includes a second matching circuit M2. One end of the second matching circuit M2 is electrically connected to the first matching point C. Furthermore, one end of the first filter 30 is provided on the second matching circuit M2 and is electrically connected to the first matching point C, and the first sub-radiator 11 is in a suspended state. The other end of the second matching circuit M2 is grounded. The second matching circuit M2 includes multiple selection branches formed by switches, capacitors, inductors and resistors, and adjustable devices such as variable capacitors. These adjustable devices are used to adjust the three resonant mode positions. Changing the mode positions can also improve the performance of a single frequency band and better meet the ENDC/CA combinations of different frequency bands.

By adding a second matching circuit M2, the second matching circuit M2 can adjust the resonant frequencies of the first resonant mode a and the second resonant mode b. For example, when the second matching circuit M2 is capacitive, the first resonant mode can be adjusted. The resonant frequencies of mode a and the second resonant mode b move toward the low-frequency end; when the second matching circuit M2 is inductive, the resonant frequencies of the first resonant mode a and the second resonant mode b can move toward the high-frequency end. Through the above adjustment, the first resonance mode a and the second resonance mode b can be made to cover the actually required frequency band and resonate at the actually required frequency.

Optionally, please refer to Figure 24. The second matching circuit M2 includes a second sub-circuit M21. The second sub-circuit M21 is electrically connected to the first matching point C. The second sub-circuit M21 is capacitive when working in the fifth frequency band. The fifth frequency band is located in the frequency band corresponding to the first resonance mode a and the second resonance mode b. For example, the fifth frequency band may be a continuous frequency band formed by the first resonance mode a and the second resonance mode b. When the second sub-circuit M21 is capacitive when operating in the fifth frequency band, the resonant frequencies of the first resonant mode a and the second resonant mode b can be moved toward the low-frequency end. The second sub-circuit M21 is similar to the free end 111 The first sub-radiator 11 between the ground point A and the first sub-radiator 11 is "connected to an effective electrical length", so when the frequency position required to resonate remains unchanged, the distance between the free end 111 and the ground point A can be relatively reduced. The actual length of the first sub-radiator 11 between the ground points A. In this way, the first sub-radiator 11 is miniaturized. After the distance between the ground point A and the free end 111 is reduced, the ground point A can be connected to 1/8 to 3/4 of the first sub-radiator 11 .

Optionally, the second sub-circuit M21 includes but is not limited to a capacitor, a series or parallel circuit containing a capacitor, an inductor, a resistor, etc.

Optionally, please refer to FIG. 25 . The second sub-radiator 12 also has a second matching point D located between the second coupling terminal 121 and the ground terminal 122 .

The antenna assembly 100 also includes a third matching circuit M3. One end of the third matching circuit M3 is electrically connected to the second matching point D. The other end of the third matching circuit M3 is connected to ground. The third matching circuit M3 includes multiple selection branches formed by switches, capacitors, inductors and resistors, and adjustable devices such as variable capacitors. These adjustable devices are used to adjust the three resonant mode positions. Changing the mode positions can also improve the performance of a single frequency band and better meet the ENDC/CA combinations of different frequency bands.

By adding a third matching circuit M3, the third matching circuit M3 can adjust the resonant frequencies of the second resonant mode b and the third resonant mode c. For example, when the third matching circuit M3 is capacitive, the second resonant frequency can be adjusted. The resonant frequencies of mode b and the third resonant mode c move toward the low-frequency end; when the third matching circuit M3 is inductive, the resonant frequencies of the second resonant mode b and the third resonant mode c can move toward the high-frequency end. Through the above adjustment, the second resonance mode b and the third resonance mode c can be made to cover the actually required frequency band and resonate at the actually required frequency.

It can be understood that when the second sub-radiator 12 serves as a sensing electrode, the first filter 30 is provided between the second sub-radiator 12 and the third matching circuit M3, so that the second The sub-radiator 12 is in a suspended state relative to the induction signal.

Referring to Figure 26, the third matching circuit M3 includes a third sub-circuit M31. The third sub-circuit M31 is electrically connected to the second matching point D. The third sub-circuit M31 is capacitive when working in the sixth frequency band. The sixth frequency band is located in the frequency band corresponding to the second resonance mode b and the third resonance mode c. For example, the sixth frequency band may be a continuous frequency band formed by the second resonance mode b and the third resonance mode c. When the third sub-circuit M31 is capacitive when operating in the sixth frequency band, the resonant frequencies of the second resonant mode b and the third resonant mode c can be moved toward the low-frequency end. The third sub-circuit M31 is similar to the second coupling mode. The second sub-radiator 12 between the terminal 121 and the ground terminal 122 is "connected to an effective electrical length", so the second coupling terminal can be relatively reduced when the frequency position required to resonate remains unchanged. The actual length of the second sub-radiator 12 between 121 and the ground terminal 122. In this way, the second sub-radiator 12 is miniaturized.

Optionally, the third sub-circuit M31 includes but is not limited to capacitors, series or parallel circuits containing capacitors, inductors, resistors, etc.

It can be understood that when actually designing the antenna assembly 100, one or two of the first matching circuit M1, the second matching circuit M2, and the third matching circuit M3 can be selected to be located at corresponding positions, or the third matching circuit M3 can be placed at the corresponding position. A matching circuit M1, a second matching circuit M2, and a third matching circuit M3 are all disposed at corresponding positions. In this way, the stack size of the radiator 10 can be further reduced.

The other end of the second filter 50 is electrically connected to the detection device 40 . Specifically, the second filter 50 is electrically connected to the first sub-radiator 11 and/or the second sub-radiator 12 . Optionally, when the first filter 30 is electrically connected to one sub-radiator 10 , the second filter 50 and the first filter 30 are electrically connected to the same sub-radiator 10 . When the first filter 30 is electrically connected to the first sub-radiator 11 and the second sub-radiator 12, the second filter 50 is electrically connected to the first sub-radiator 11 and/or the second sub-radiator 11. Two sub-radiators12. The second filter 50 is used to block the radio frequency signals and conduction induction signals sent and received by the radiator 10, so that the radio frequency signals sent and received by the radiator 10 will not affect the detection accuracy of the induction signal detected by the detection device 40. .

Of course, in other embodiments, the detection device 40 itself has the function of passing the induction signal and blocking the radio frequency signal, or the detection device 40 can only be affected by the induction signal but not by the radio frequency signal. In this case, there is no need to The second filter 50 is provided to reduce the number of components, simplify the circuit structure and save space.

Since the radiator 10 of the antenna assembly 100 has the function of sensing human body proximity and transmitting and receiving radio frequency signals at the same time, in order to prevent the induction signal and the radio frequency signal from interfering with each other, the first filter 30 and the first filter 30 are provided in the antenna assembly 100 The second filter 50 , wherein the first filter 30 prevents the sensing signal from flowing through the radio frequency front-end unit 20 or the ground electrode GND, and the second filter 50 prevents the sensing signal from flowing to the The detection device 40 is used to detect the induction signal. In addition, the second filter 50 prevents the radio frequency signal from flowing through the detection device 40, and the first filter 30 prevents the radio frequency signal from flowing through the radio frequency front-end unit 20 and the ground electrode GND, so the electromagnetic wave signal is realized.

Further, both the first sub-filter 31 and the second sub-filter 32 are capacitors. Both the first sub-filter 31 and the second sub-filter 32 have isolation effect on the induction signal. In other words, the first filter 30 causes the first sub-radiator 11 to be in a "suspended" state relative to the induction signal. In this way, when the human body approaches, the first sub-radiator 11 can sense the charge brought by the human body. Quantity changes. The second filter 50 is electrically connected to the first sub-radiator 11 . The above-mentioned change in charge amount forms an induction signal, and the induction signal is transmitted to the detection device 40 through the second filter 50. The detection device 40 detects whether the above-mentioned induction signal is greater than or equal to a preset intensity value to determine whether the human body is The first sub-radiator 11 is close to the antenna assembly 100 .

It should be noted that in this application, when the distance between the human skin surface and the antenna assembly 100 is less than or equal to x, the human body is close to the antenna assembly 100 . When the distance between the human skin surface and the antenna assembly 100 is equal to x, the intensity value of the induction signal detected by the detection device 40 is N, and N is a preset intensity value. When the detection device 40 detects that the intensity value of the induction signal is greater than or equal to N, the detection device 40 detects that the human body is close to the first sub-radiator 11 of the antenna assembly 100 .

The third sub-filter 33 is a capacitive device, and the third sub-filter 33 is used to block induction signals and conduct radio frequency signals. In this way, the third sub-filter 33 makes the second sub-radiator 12 be in a "suspended" state relative to the induction signal. Therefore, the third sub-filter 33 makes the second sub-radiator 12 form a filter for detecting the induction signal. Sensing electrode.

In the first case, the second filter 50 is electrically connected to the first sub-radiator 11. In this case, the second filter 50 is electrically connected to the first sub-radiator 11. Both the first sub-radiator 11 and the second sub-radiator 12 can be used as sensing electrodes. When a human body approaches the first sub-radiator 11, the charge on the first sub-radiator 11 changes, and the detection The device 40 can directly sense the induction signal through the second filter 50; when the human body approaches the second sub-radiator 12, the charge on the second sub-radiator 12 changes, and the second sub-radiator 12 passes through The coupling gap generates a coupling induction signal on the first sub-radiator 11. The detection device 40 detects the approach of the human body by detecting the coupling induction signal. In this case, all the radiators 10 can be used as induction electrodes to detect By making the sensing area larger and utilizing the coupling gap between the sub-radiators 10 of the antenna assembly 100 to realize the transmission of induction signals, the utilization rate of the radiators 10 can be improved, and only two sub-radiators 10 can be used. Only one detection device 40 is required, which can save the number of components of the antenna assembly 100 and save space.

In other words, the same detection device 40 detects the induction signals detected by the first sub-radiator 11 and the second sub-radiator 12 to reduce the number of the detection devices 40 and save space. In this embodiment It is applicable to the case where the first sub-radiator 11 and the second sub-radiator 12 are both located on the same side, or the superposition volume of the first sub-radiator 11 and the second sub-radiator 12 is small. Case.

Alternatively, please refer to FIG. 29 , the detection device 40 includes a first sub-detector 41 and a second sub-detector 42 .

In other words, two independent sub-detectors are used to detect the induction signals detected by the first sub-radiator 11 and the second sub-radiator 12 respectively. This embodiment can be used for the first sub-radiator. When 11 and the second sub-radiator 12 are respectively located on different sides of the electronic device 1000, the approach of human bodies from different sides of the electronic device 1000 can be detected through the radiator 10 of one antenna assembly 100.

Specifically, the controller can adjust the power of the radio frequency front-end unit 20 (ie, the power of the antenna assembly 100) according to different scenarios.

For example, when the human head is close to the radiator 10 of the antenna assembly 100, the controller can reduce the power of the antenna assembly 100 to reduce the specific absorption rate of the electromagnetic waves radiated by the antenna assembly 100. When human hands block the radiator 10 of the antenna assembly 100 in the radiation direction, other backup antenna assemblies 100 (that is, antenna assemblies that can cover the same frequency band) are also provided in the electronic device 1000 100), the controller can turn off the blocked antenna component 100 and turn on the antenna component 100 that is not blocked in other positions. In this way, when the antenna component 100 is blocked by the human hand, the controller can switch the antenna component 100 through intelligent switching. The antenna assembly 100 can ensure the communication quality of the electronic device 1000; when no other spare antenna assembly 100 is installed in the electronic device 1000, the controller can control the power increase of the antenna assembly 100. , to compensate for the problem of reduced efficiency caused by blocking the radiator 10 by the hand.
