In the embodiment of the present disclosure, the main antenna 21 is disposed at the bottom region of the terminal housing 10, and the first diversity antenna 22 is disposed at the top region of the terminal housing 10. The gap between the main antenna 21 and the first diversity antenna 22 may be provided on the side surface of the terminal housing 10 (as shown in fig. 1) or may be provided at the tip of the terminal body (as shown in fig. 2). It should be noted that the top area and the bottom area of the mobile terminal 20 are defined by the user's common usage habit in the vertical direction of the mobile terminal 20, and the size of the top area and the bottom area may be specifically defined according to the size of the main antenna 21 and the first diversity antenna 22.
The close proximity of the user to the head during the use of the mobile terminal 100 may cause a significant degradation in antenna performance. Thus, the terminal body 20 of the present disclosure further includes a second diversity antenna 23 disposed corresponding to at least one side region of the terminal housing 10. Here, the side regions corresponding to the terminal housing 10 refer to: the second diversity antenna 23 is disposed on the terminal body 20, and after the terminal body 20 is assembled in the terminal housing 10, the second diversity antenna 23 is close to a side frame of the terminal housing 10, and the second diversity antenna 23 is located on the mobile terminal 100 in a side area of the mobile terminal 100. In this embodiment, the second diversity antenna 23 is set in the side area of the mobile terminal 100, and the intelligent switching technology of the mobile terminal 100 is combined, so that the antenna switching is performed when there is a signal interference factor on the mobile terminal 100, thereby achieving better communication performance of the mobile terminal 100 and improving user experience.
The main antenna 21, the first diversity antenna 22 and the second diversity antenna 23 respectively include a grounding point and a feeding point, the main antenna 21, the first diversity antenna 22 and the second diversity antenna 23 are connected to the control panel through respective feeding points through lines, and the main antenna 21, the first diversity antenna 22 and the second diversity antenna 23 are respectively connected to the grounding elastic sheet through respective grounding points. When the frame of the terminal housing 10 is a metal frame, the main antenna 21, the first diversity antenna 22 and the second diversity antenna 23 may be connected to the metal frame through respective grounding points.
In the present disclosure, the mobile terminal 100 may be a mobile phone, a PDA (Personal Digital Assistant), a mobile computer, a tablet computer, a wearable device, or the like. The main antenna 21, the first diversity antenna 22 and the second diversity antenna 23 in the mobile terminal 100 are integrated in one or a combination of a metal frame, LDS (Laser-Direct-structuring), PFC (Flexible Printed Circuit board) or LCP (Liquid Crystal Polymer). Specifically, the antenna types of the antenna 21, the first diversity antenna 22, and the second diversity antenna 23 are an IFA antenna, a monopole antenna, or an inverted-L antenna, or their variants, and the like.
Preferably, the second diversity antenna 23 is a side slot antenna. The slot of the side slot antenna is in a strip shape, and the length of the slot antenna is about half wavelength of a low-frequency mode. The length direction of the side slot antenna is identical to the length direction of the mobile terminal 100.
Referring to fig. 1 to 3, in one embodiment, the second diversity antenna 23 is disposed near a top area of the terminal housing 10. The grounding point of the second diversity antenna 23 is disposed at an end of the second diversity antenna 23 near the top area of the terminal housing 10, and the end has a certain space range so that the grounding point of the second diversity antenna 23 can have a plurality of position options according to requirements.
Referring to fig. 4, in yet another embodiment, the second diversity antenna 23 is disposed near a bottom region of the terminal housing 10. The grounding point of the second diversity antenna 23 is disposed at an end of the second diversity antenna 23 near the bottom region of the terminal housing 10, and the end has a certain space range so that the grounding point of the second diversity antenna 23 can have multiple position options according to requirements.

Wherein the break of the second diversity antenna 23 is located in the middle area of the terminal body 20, and the second diversity antenna 23 is grounded at a corner position (located near the top area or the bottom area of the terminal housing 10).
In the above embodiments, the middle area is an area between the top area and the bottom area, and the range size of the specific middle area may be set according to the size of the second diversity antenna 23, and is not particularly limited herein. Preferably, the break of the second diversity antenna 23 is provided on or near the middle line of the terminal body 20 in the lateral direction.
Of course, the number of the second diversity antennas 23 in the present disclosure is not limited to two, and a plurality of second diversity antennas 23 may be disposed in the side area of the mobile terminal 100 according to the communication requirement, and the positions of the break and the ground point of the second diversity antenna 23 may be arbitrarily set. In addition, referring to fig. 4, in the case of having one second diversity antenna 23, the second diversity antenna 23 may also be disposed in the middle area of the side area of the mobile terminal 100.
Further, as shown in fig. 1 to 6, the mobile terminal 100 of the present disclosure further includes a GPS antenna 24 and a WiFi antenna 24. Because the size of the first diversity antenna 22 is smaller than that of the main antenna 21, the GPS antenna 24, the WiFi antenna 24 and the first diversity antenna 22 are located at the same end of the terminal housing 10, and the GPS antenna 24 and the WiFi antenna 24 may be integrally disposed or disposed at any position of the terminal main body 20 according to the structural layout. In the embodiment of the present disclosure, the main antenna 21 corresponds to a bottom area of the terminal housing 10, and the GPS antenna 24, the WiFi antenna 24 and the first diversity antenna 22 correspond to a top area of the terminal housing 10. Of course, the main antenna 21 may be disposed corresponding to the top region of the terminal housing 10, and the GPS antenna 24, the WiFi antenna 24 and the first diversity antenna 22 may be disposed corresponding to the bottom region of the terminal housing 10.
