Detailed Description
Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.
Fig. 1 is a schematic diagram of an antenna structure of a mobile terminal of one embodiment of the present disclosure; as shown in fig. 1, the antenna structure of the mobile terminal of the present embodiment includes: a first antenna component 10, one end of the first antenna component 10 being connected to the feeding point 20; a second antenna unit 30 and a third antenna unit 40 respectively disposed at both sides of the first antenna unit 10, one end of each of the second antenna unit 30 and the third antenna unit 40 being connected to a ground point 50; and a fourth antenna assembly 70 disposed in the frame 60, wherein a first gap 100 is formed between the first end 71 of the fourth antenna assembly 70 and the frame 60, a second gap 200 is formed between the second end 72 of the fourth antenna assembly 70 and the frame 60, and the other end of the second antenna assembly 30 is connected to the first end 71 of the fourth antenna assembly 70.
Specifically, the first antenna assembly 10 may be a monopole antenna, and since the length of the antenna is determined according to the wavelength of the transmitted and received signal, the longer the wavelength of the transmitted and received signal is, i.e., the lower the frequency is, the longer the length of the required antenna is, the longer the length of the antenna is required if the antenna is required to be resonated in the low frequency band, and the shorter the length of the antenna is required if the antenna is required to be resonated in the high frequency band.
The first antenna assembly 10 is connected to a feeding point 20, and the feeding point 20 is used for connecting to a feeder of a mobile terminal, receiving a communication signal pre-transmitted from the mobile terminal from the feeder or transmitting the received communication signal to the mobile terminal through the feeder.
A distance is formed between the second antenna assembly 30 and the first antenna assembly 10, and the frequency band adjustment is realized by adjusting the distance between the second antenna assembly 30 and the first antenna assembly 10, namely, adjusting the coupling amount between the second antenna assembly 30 and the first antenna assembly 10; similarly, a distance is formed between the third antenna element 40 and the first antenna element 10, and the frequency band is adjusted by adjusting the distance between the third antenna element 40 and the first antenna element 10, that is, by adjusting the coupling amount between the third antenna element 40 and the first antenna element 10.
In this embodiment, the frame 60 may be a metal frame, which has an attractive appearance and a good texture, but because the enclosed metal frame can form an interference shield for electromagnetic waves radiated by the antenna, the radiation capability of the antenna is affected, and the communication performance of the mobile terminal is further affected. Therefore, in the present embodiment, the two gaps are formed on the frame 60, and the first gap 100 and the second gap 200 are formed on the frame 60, so that the antenna signal is not completely blocked by the metal frame, and a radiation space communicated with the outside is obtained.
Generally, the frame 60 of the mobile terminal is rectangular, the frame 60 includes two opposite side frames for holding by hands and a top frame and a bottom frame between the two side frames, if the hands of the user block the first gap 100 and/or the second gap 200, the radiation effect of the antenna is affected, and the communication performance of the mobile terminal is affected, therefore, in this embodiment, the first gap 100 and the second gap 200 are disposed at the top of the frame 60, i.e., disposed on the top frame, the influence of the head and the hands of the human body on the radiation performance of the antenna can be effectively reduced, and the communication performance of the mobile terminal is ensured.
The larger the size of the first gap 100 and the second gap 200 is, the smaller the reflection and consumption of electromagnetic waves by the bezel 60 (metal bezel) is, and the higher the bandwidth and radiation efficiency of the antenna is. Therefore, the adjustment of the antenna bandwidth can also be achieved by adjusting the sizes of the first gap 100 and the second gap 200.
The border between the first gap 100 and the second gap 200 is connected to the second antenna component 30, whereby the segment of the border forms the fourth antenna component 70.
The present embodiment can control different resonant frequency bands by adjusting the spacing between the second antenna element 30 and the first antenna element 10, the spacing between the third antenna element 40 and the first antenna element 10, the size of the first gap 100, the size of the second gap 200, the shape of each antenna element, and the like. The frequency band of the current mobile communication is generally 700MHz-2700 MHz. The present disclosure can achieve good performance of the entire communication band by adjusting the above parameters. For example, the frequency band adjustment between 1710MHz and 2170MHz is realized by adjusting the spacing between the second antenna assembly 30 and the first antenna assembly 10 and/or the shape structure of the second antenna assembly 30; the frequency band adjustment between 700MHz and 960MHz is realized by adjusting the shape structure of the second antenna component 30 and/or adjusting the first gap 100 and the second gap 200; the adjustment of the frequency band between 2300MHZ to 2700MHZ is achieved by adjusting the spacing between the first antenna assembly 10 and the third antenna assembly 40 and/or the shape of the first antenna assembly 10 and the third antenna assembly 40.
In order to achieve the above object, and considering the size standard of the mobile terminal, the present embodiment preferably has a distance between the second antenna assembly 30 and the third antenna assembly 40 and the first antenna assembly 10 of 1mm to 2 mm.
While different shapes of the antenna components can have different effects on the performance of the antenna, in the disclosed embodiment, the second antenna component 30 and the third antenna component 40 are preferably rectangular in shape.
According to the antenna structure provided by the embodiment of the disclosure, the coverage of a wide frequency band is realized through the electromagnetic coupling of each antenna component, the bandwidth of the antenna is effectively widened, and the communication performance of the mobile terminal is improved.
With reference to fig. 1, based on the above embodiment, the antenna structure of the mobile terminal further includes a fifth antenna assembly 80, one end of the fifth antenna assembly 80 is connected to the second end 72 of the fourth antenna assembly 70, and by further disposing the fifth antenna assembly 80, the bandwidth of the antenna can be further increased through the fifth antenna assembly 80.
The USB interface module 300 may be further disposed between the third antenna module 40 and the fifth antenna module 80, and a distance between the third antenna module 40 and the fifth antenna module 80 and the USB interface module 300 is greater than 2mm, since the USB interface module 300 is a metal device, in order to prevent the metal device from coupling with the antenna and affecting the performance of the antenna, when the size of the internal space of the mobile terminal is satisfied, the distance between the USB interface module 300 and its neighboring antenna modules should be increased as much as possible, that is, the distance between the third antenna module 40 and the fifth antenna module 80 and the USB interface module 300 should be increased.
Fig. 2 is a schematic structural diagram of a mobile terminal according to an embodiment of the present disclosure. As shown in fig. 2, an embodiment of the present disclosure further provides a mobile terminal including the antenna structure of the mobile terminal as described above.
The mobile terminal may further include: a motor 400, the motor 400 is located below the second antenna assembly 30, and the distance between the motor 400 and the second antenna assembly is greater than 2 mm.
And may further include a speaker 500, the speaker 500 being located at one side of the first antenna assembly 10, and a distance between the speaker and 500 the first antenna assembly 10 being greater than 2 mm.
In this embodiment, the motor 400 and the speaker 500 are disposed on the top of the mobile terminal, which meets the basic design requirement of the mobile terminal, and is as far away from the antenna assembly as possible, so as to reduce the influence of metal devices such as the motor 400 and the speaker 500 on the antenna performance, and further ensure the communication performance of the whole mobile terminal.
