Problems solved by technology

[0003] However, when the user holds the mobile phone to make a call or operate, sometimes the palm of the hand will just hold the antenna part of the mobile phone, which will affect the signal of the antenna and reduce the performance of the antenna. For example, the antenna part of the mobile phone is set on the back of the mobile phone. Hold the phone just so that the palm of the hand will completely cover the antenna part set on the back of the phone
This makes the user have problems such as unclear voice during the call, and even unable to use the mobile phone to complete the call.
[0004] In the related art, although a multi-antenna system can be set in the wireless smart terminal, when the signal of a certain antenna is detected to become weak or the hand is detected to hold a certain antenna, it will automatically switch to another antenna, but if the switched to this one If the antenna is located on the top of the mobile phone, the radiation of the antenna to the human body will be too large

Embodiment Construction

[0109] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0110] figure 1 It is a flow chart of an antenna control method according to an exemplary embodiment. The antenna control method can be applied to a wireless terminal that includes an antenna, such as a mobile phone, a tablet computer, etc., where at least two antennas are included in the wireless terminal, and at least two antennas in the wireless terminal can be switched to each other. When ...

Abstract

The invention relates to an antenna control method and device to be applied to terminals including at least two antennae. The method comprises detecting a receiving level of a working antenna that is using by the terminal at present; determining whether the receiving level of the working antenna meets preset switching triggering conditions; selecting one spare antenna as the target antenna from the spare antennae remained in at least two antennae; switching the target antenna to the work state; determining whether the target antenna is disposed in a preset position on the terminal; controlling transmission power of the target antenna to be reduced when the target antenna is disposed in the preset position on the terminal. By means of the method and the device, output power can be reduced apparently when the target antennae which are serious in radiation to users and in the preset positions, and accordingly, the effect on user health due to intense radiation is prevented.

Description

technical field [0001] The present disclosure relates to the technical field of antennas, and in particular to an antenna control method and device. Background technique [0002] In real life, wireless smart terminals such as mobile phones have become an indispensable tool for information exchange in people's daily life. [0003] However, when the user holds the mobile phone to make a call or operate, sometimes the palm of the hand will just hold the antenna part of the mobile phone, which will affect the signal of the antenna and reduce the performance of the antenna. For example, the antenna part of the mobile phone is set on the back of the mobile phone. Hold the mobile phone just so that the palm completely blocks the antenna part arranged on the back of the mobile phone. This makes the user's voice unclear when talking, and even unable to use the mobile phone to make a complete call. [0004] In the related technology, although a multi-antenna system can be set in the...
