Embodiment 1
[0072] refer to figure 1 , the antenna device of the first embodiment of the present invention is proposed, the device is applied to a mobile terminal, including a sensing module, a switching module, a radio frequency signal source, a tuning module and an antenna body, and the switching module, the radio frequency signal source and the tuning module can all be arranged On the printed circuit board of the mobile terminal, an application processor (AP) of the mobile terminal can be reused as a switching module. The end of the antenna body close to the microphone of the mobile terminal is the lower antenna of the mobile terminal, and the antenna body is connected to a radio frequency signal source through a tuning module. The sensing module is used for sensing the shielding state of the antenna body, and the switching module is used for switching the tuning state of the tuning module according to the shielding state, so as to avoid the performance deterioration of the antenna cau...
Embodiment 2
[0100] refer to Figure 4 , propose the antenna switching method of the second embodiment of the present invention, the method includes the following steps:
[0101] S11. Sensing the shielding state of the antenna body, which is close to the microphone end of the mobile terminal and connected to a radio frequency signal source through a tuning module.
[0102] S12. Switch the tuning state of the tuning module according to the shielding state, where the tuning state at least includes a first state and a second state.
[0103] In the embodiment of the present invention, a sensing unit is provided at one or at least two positions of the mobile terminal. The sensing unit can be any conductive element, such as metal element, conductive glue, conductive film, conductive plating, metal pattern, etc., wherein the metal element is metal sheet, metal strip, metal wire, etc. During specific implementation, the sensing unit can adopt FPC, metal sheet (such as stainless steel sheet), LDS...

Abstract
The invention discloses an antenna device, an antenna switching method and a mobile terminal. The device comprises a sensing module, a switching module, a radio frequency signal source, a tuning module and an antenna body, wherein the antenna body is close to microphone end of the mobile terminal, and is connected with the radio frequency signal source through the tuning module; the sensing module is used for sensing a shielding status of the antenna body; the switching module is used for switching a tuning status of the tuning module according to the shielding status, wherein the tuning status at least comprises a first status and a second status. Therefore, the antenna performance deterioration is avoided by sending the shielding status of the antenna body at the lower part of the mobile terminal and switching the tuning status of the tuning module according to the shielding status, the performance balance of each of the left hand and right hand of the antenna is maintained, and the antenna performance when the mobile terminal is held is improved, and then the online and call experience when the user holds the mobile terminal are improved. An upper antenna can be omitted, thereby solving the problem that the head SAR testing caused by the upper antenna is hard to pass.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to an antenna device, an antenna switching method and a mobile terminal. Background technique [0002] The antenna performance of mobile terminals such as mobile phones directly affects the quality of communication signals of mobile terminals, which in turn affects the user's call and Internet experience. When a user holds a mobile terminal with his left or right hand, it usually covers part of the antenna, thereby deteriorating the performance of the antenna. Therefore, how to prevent the performance of the antenna from deteriorating when the mobile terminal is held by the left and right hands, that is, how to maintain the performance balance between the left and right hands of the antenna, is a difficult point in current antenna design. [0003] For traditional mobile terminals with plastic back covers, it is still possible to balance the influence of left and right...
