Embodiment 1

[0070] refer to figure 1 , the antenna device according to the first embodiment of the present invention is proposed. The device is applied to a mobile terminal and includes a sensing module, a switching module, a radio frequency signal source and an antenna body. The radio frequency signal source can be arranged on a printed circuit board of the mobile terminal. 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 includes a first feeding point and a second feeding point respectively located on the left and right sides of the mobile terminal. The sensing module is used to sense the shading state of the antenna body, and the switching module is used to switch the signal feeding point of the antenna body between the first feeding point and the second feeding point according to the shading state, so as to avoid the The antenna performance is deteriorated due to shadowing.

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 and an antenna body, wherein the antenna body is close to one end of a microphone of the mobile terminal and comprises a first feed point and a second feed point which are positioned on the left and the right of the mobile terminal respectively, and the sensing module is used for sensing the shielding state of the antenna body, the switching module is used for switching a signal feed point of the antenna body between the first feed point and the second feed point according to the shielding state. Therefore, by sensing the shielding state of the antenna body on the lower portion of the mobile terminal and switching the signal feed point of the antenna body between the first feed point and the second feed point according to the shielding state, antenna performance deterioration is avoided, left and right performance balance of an antenna is kept, the antenna performance of the mobile terminal held with a hand is improved, and internet surfing experience and call experience of a user holding the mobile terminal with the hand are further improved.

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...
