Abstract

A mobile terminal for automatically adjusting antenna matching, and a control method thereof, are provided. By determining whether an RSSI value is less than a preset value, a mobile terminal, and a control method thereof, may send an SPI control signal according to a judgment result, and an SPI control interface may transmits the SPI control signal to an antenna matching module to control a magnitude of variable capacitance and variable inductance. Thereby antenna matching impedance may be adjusted to increase an RSSI value. A mobile terminal, and a control method thereof, may include a good communication signal and high call quality.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a mobile terminal for automatically adjusting antenna matching and a control method thereof. Background technique [0002] At present, RSSI (Received Signal Strength Indication, received signal strength indication) is commonly used in mobile communication to determine the link quality and indicate the strength of the communication signal. Generally, when the RSSI is set at about 90dbm, it means that the signal is good. If the RSSI value is less than 70dbm, there will be dropped calls, crosstalk, poor voice quality, and difficulty in networking during communication. The value of RSSI is related to factors such as wireless environment, signal strength, call frequency and antenna matching. In the design of mobile phones, the matching impedance of the antenna matching circuit is often adjusted to match the receiving ability of the antenna to the best state, thereby increasing...
