Abstract

The invention provides an antenna transmitting power adjusting method, an antenna transmitting power adjusting device and a mobile terminal. The antenna transmitting power adjusting method comprises the following steps of: establishing a mapping relation table between capacitance values and distance values at different temperatures, wherein the capacitance values are capacitance, detected by a capacitive proximity sensor, between a radiation body and a to-be-detected main body, the distance values are the distance, determined according to the capacitance values, between the radiation body andthe to-be-detected main body, the mapping relation table comprises a plurality of mapping relations, and each mapping relation corresponds to one temperature; acquiring a current capacitance value detected by the capacitive proximity sensor and a current distance value detected by a light sensing proximity sensor; determining a target mapping relationship in the mapping relationship table according to the current distance value and the current capacitance value; and adjusting transmitting power of an antenna according to the target mapping relationship. According to the antenna transmitting power adjusting method, the antenna transmitting power adjusting device and the mobile terminal provided by the invention, the antenna transmitting power of the detection accuracy of the capacitive proximity sensor can be improved.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a method, device and mobile terminal for adjusting the transmission power of an antenna. Background technique [0002] With the development of mobile communications, handheld mobile terminals are getting closer to people's lives, and people use mobile terminals with increasing frequency and usage time, such as mobile phones and tablets. SAR (Specific Absorption Rate, electromagnetic wave absorption ratio), is the electromagnetic wave energy absorption ratio of mobile phones or wireless products. It is defined as: under the action of an external electromagnetic field, an induced electromagnetic field will be generated in the human body. The international scientific community uses "SAR" value to radiate mobile phones Quantify and measure. The SAR sensor is a capacitive proximity sensor that detects whether the distance between the mobile terminal and the human bo...
