Abstract

The invention proposes a mobile terminal and a method for tuning an antenna. The method comprises the following steps: receiving a transmitting signal of a transmitting antenna and detecting the strength of the received transmitting signal; and if the strength of the received transmitting signal is lower than a set threshold value, then adjusting the strength of the transmitting signal of the transmitting antenna to a preset value by adjusting a tuning matching parameter of the transmitting antenna. According to the mobile terminal and the method for tuning the antenna provided by the invention, real-time near-distance sampling can be carried out on the spatial distribution strength of radiation signals of the transmitting antenna, so that the actual radiation signal strength of the antenna is monitored, the antenna tuning matching adjustment precision is further improved, and the communication quality of the mobile terminal is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a mobile terminal and a method for tuning an antenna. Background technique [0002] In the prior art, the communication terminal detects the transmit power of the power amplifier and the reflected power of the antenna end by adding a coupling loop to the RF front end of the transmit branch, determines the return loss of the antenna, calculates the matching parameters of the antenna, and controls the voltage control The variable capacitance matches the antenna to the best matching state; or the communication terminal monitors RSSI (Received Signal Strength Indication) through the baseband module, calculates the matching parameters of the antenna, and controls the variable capacitance and The variable inductance is used to adjust the antenna matching parameters, match the antenna to the best matching state, increase the RSSI value, and ensure the call quality of the communic...
