Method for adjusting radiation direction of mobile terminal, and mobile terminal

Abstract

The invention discloses a method for adjusting the radiation direction of a mobile terminal, and a mobile terminal. The mobile terminal comprises a proximity switch, antennas and a control unit, wherein the proximity switch is used for detecting the distance between a human face and the mobile terminal; the antennas are used for emitting and receiving data and comprise a first-state antenna and a second-state antenna, and the electromagnetic wave absorption ratio SAR value tested by the first-sate antenna is smaller than the SAR value tested by the second-state antenna; and the control unit is used for controlling the antennas to select the first-sate antenna for radiation when the proximity switch detects that the human face is approaching the mobile terminal, and controlling the antennas to select the second-sate antenna for radiation when the proximity switch detects that the human face is away from the mobile terminal. By using the mobile terminal provided by the invention, the unfavorable influence that the mobile terminal exerts on a human body, a hearing aid and the like can be reduced by detecting the distance between the human face and the mobile terminal, and under the condition that the radiation performance of the mobile terminal is ensured, the SAR values and HAC values can be reduced and the user experience and radio frequency performance can be improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular, to a method for adjusting the radiation direction of a mobile terminal and the mobile terminal. Background technique [0002] With the rapid development of mobile communications, people have higher and higher requirements for radio frequency radiation of mobile phone terminals, from the basic OTA (Over The Air) performance to the mobile phone radiation index SAR (Specific Absorption Rate, electromagnetic wave absorption ratio or specific absorption rate). ), HAC (Hearing Aid Compatibility, hearing aid compatibility), etc., the design of mobile phone radio frequency and antenna is becoming more and more difficult. It is not only necessary to ensure the radiation performance of the mobile phone, but also to ensure that the impact of the antenna on human radiation and hearing aids is as small as possible. Such seemingly contradictory performance requirements ...
