Abstract

The embodiment of the invention provides an antenna tuning method and a terminal. The method comprises the steps of obtaining a first working frequency band of a first antenna under the condition that the first antenna is in a working state and a second antenna is in a standby state; determining a target radio frequency path corresponding to the first working frequency band in the at least two second radio frequency paths according to a preset corresponding relation between the working frequency band of the first antenna and the at least two second radio frequency paths; and controlling the second power amplification unit to conduct the second antenna and the target second radio frequency. According to the embodiment of the invention, the radiation power of the antenna in the working state is adjusted by utilizing other antennas and the load on the radio frequency path which can be connected with the other antennas, so that the antenna can work with better working efficiency, thereby saving the use of an antenna tuner and reducing the production cost of the terminal.

Description

technical field [0001] Embodiments of the present invention relate to the field of communications 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 have brought great convenience to all aspects of people's lives. There will be an antenna tuning circuit inside the terminal, and there will be an antenna tuner in the antenna tuning circuit. When the antennas are mismatched, the antenna tuner can adjust according to the degree of mismatch of the antennas. Since the input impedance of the antenna changes 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 does not match, which will reduce the Th...
