Abstract

The invention provides an antenna control method and a mobile terminal, belonging to the technical field of communication. The antenna control method specifically comprises the following steps: acquiring the signal strength of each antenna in the mobile terminal; determining a signal strength difference value according to the signal strength of the transmitting antenna and the signal strength of at least one receiving antenna; when the signal strength difference satisfies a first preset condition, the electromagnetic wave absorption ratio is reduced. In the antenna control method of the embodiment of the present invention, the operation of the user approaching or touching the mobile terminal can be detected by acquiring the signal strength of each antenna in the mobile terminal, and then,the electromagnetic wave absorption ratio is reduced to avoid electromagnetic radiation damage to the user caused by the transmitting antenna.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to an antenna control method and a mobile terminal. Background technique [0002] With the user's pursuit of the ultimate user experience, the user has higher and higher requirements for the performance of the mobile terminal, and it is often necessary to install multiple antennas in the mobile terminal to improve communication performance. In order to enable the antennas of the mobile terminal to still achieve better communication performance in various application scenarios, these antennas often need to be arranged at multiple positions of the mobile terminal. [0003] In practical applications, when a user uses a mobile terminal, he often approaches one or more antennas in the mobile terminal. However, when the antenna close to the user is the transmitting antenna in the mobile terminal, it is often easy to cause the electromagnetic wave absor...
