Abstract

Embodiments of the present invention provide an antenna tuning method and a terminal. The method includes: when the first antenna is in the working state and the second antenna is in the standby state, acquiring the first working frequency band of the first antenna; according to the preset working frequency band of the first antenna and the corresponding relationship between the at least two second radio frequency channels, determine the target radio frequency channel corresponding to the first working frequency band among the at least two second radio frequency channels; control the second power amplifying unit to turn on The second antenna communicates with the target second radio frequency. In the embodiment of the present invention, the radiation power of the antenna in the working state is adjusted by using other antennas and the load on the radio frequency path that can be connected with other antennas, so that the antenna can work with better working efficiency, which can save The use of the antenna tuner is eliminated, and the production cost of the terminal is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to an antenna tuning method and a terminal. Background technique [0002] With the rapid development of terminals (such as mobile phones), terminals have generally entered people's lives and brought great convenience to all aspects of people's lives. There will be an antenna tuning circuit inside the terminal, and there is an antenna tuner in the antenna tuning circuit. When the antenna is mismatched, the antenna tuner can adjust according to the degree of mismatch of the antenna. Since the input impedance of the antenna will change greatly with the frequency, and the output impedance of the transmitting unit is constant, if the transmitting unit is directly connected to the antenna, when the frequency of the transmitting unit changes, the impedance between the transmitting unit and the antenna will not match, and it will decrease. The radiated ...
