Embodiment 1

[0073] refer to figure 1 , an antenna switching device according to a first embodiment of the present invention is proposed, the device is applied to a mobile terminal, and includes a sensing module and a switching module. The sensing module includes at least one sensing unit, which is used to sense the change information of the parasitic capacitance generated when the limb approaches the sensing unit through the sensing unit, and determine the shielding state of the antenna system of the mobile terminal according to the change information of the parasitic capacitance; the switching module Used to perform antenna switching actions based on the shadowing status of the antenna system. The limbs mainly refer to human hands, and of course may also be other electrical conductors. The following uses human hands as an example.

[0074] Traditional sensor devices such as light sensors, distance sensors, etc., can also detect the shielding state of the antenna system, but they will oc...

example 1

[0089] The switching module can perform up-down antenna switching on the antenna system according to the shaded state of the antenna system.

[0090] For example: when the left side and / or right side of the lower antenna of the antenna system are shaded, switch the currently working antenna to the upper antenna; when the lower antenna of the antenna system is not shaded or the left side and / or right side of the upper antenna are shaded, then Switch the currently working antenna to the lower antenna. The specific switching manner is the same as that of the prior art, and will not be repeated here.

example 2

[0092] The switching module can switch the left and right feeding points of the lower antenna of the antenna system according to the shade state of the antenna system.

[0093] Such as Figure 4 As shown, it is a schematic diagram of the circuit connection of the lower antenna 10 , the switching module and the radio frequency signal source 30 . Wherein, the lower antenna 10 includes a first feed point feed1 and a second feed point feed2 respectively located on the left and right sides of the mobile terminal, the switching module includes a control unit 21 and a switch K, and the lower antenna 10 is connected to the radio frequency signal through the switch K The source 30, the control unit 21 is used to control the switch K switchable connection between the first feed point feed1 of the lower antenna 10 and the radio frequency signal source 30 or the second feed point feed2 of the lower antenna 10 and the radio frequency signal source 30, so that The first feed point feed1 or...

Abstract

The invention discloses an antenna switching device and method, and a mobile terminal. The device comprises a sensing module and a switching module, the sensing module comprises a sensing unit, wherein the sensing module is used for sensing change information of stray capacitance generated when a limb approaches to the sensing unit through the sensing unit, and determining a shielding state of an antenna system according to the change information of the stray capacitance; and the switching module is used for judging whether the signal of a current working frequency band is deteriorated, and executing an antenna switching action according to the shielding state when the signal of the current working frequency band is deteriorated. Therefore, the situation that the antenna system is shielded when the mobile terminal is held on a left hand or a right hand can be detected, the antenna is switched accordingly to keep the balance and left and right hand performance of the antenna and improve the network access experience and call experience when the mobile terminal is held on the hand of a user. Moreover, the antenna switching action is executed only when the signal of the current working frequency band is deteriorated, thereby reducing the switching times, reducing the energy consumption and improving the stability of the system.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to an antenna switching device, method and 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 hands by ra...
