An antenna tuning method and a wireless terminal

Abstract

The invention discloses an antenna tuning method and a wireless terminal, the wireless terminal comprising: an antenna module, comprising a main antenna, a parasitic component of the main antenna; Wherein the main antenna is electrically connected with a radio frequency front end module through a radio frequency impedance transmission line, and the parasitic component is electrically connected with the radio frequency impedance transmission line through a first channel electrically connected with the radio frequency switch module; The first channel is a channel in at least one channel betweenthe parasitic assembly and the radio frequency switch module; A processing module, configured to detect a wireless signal received from an antenna module, and switch the radio frequency switch moduleto a second channel when a signal indication value of the wireless signal is less than a threshold value, so that the parasitic component is electrically connected with the radio frequency impedance transmission line through the second channel; The second channel is a channel in which a signal indication value of a corresponding wireless signal is the largest among the at least one channel.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an antenna tuning method and a wireless terminal. Background technique [0002] With the development of wireless communication technology, the performance of processors and radio frequency modules in wireless terminals has been greatly improved. However, with the development of miniaturization of wireless terminals, it has brought challenges to the design of antennas in wireless terminals. The quality of the performance determines the communication quality of the wireless terminal communication. [0003] At present, the antenna in the wireless terminal is generally fixed inside the wireless terminal, and the directivity of the antenna is greatly affected by the position of the antenna. When the position between the wireless terminal and the signal source is fixed, if the direction of the antenna of the wireless terminal is not optimal for receiving Direction will cau...

[0003] At present, the antenna in the wireless terminal is generally fixed inside the wireless terminal, and the directivity of the antenna is greatly affected by the position of the antenna. When the position between the wireless terminal and the signal source is fixed, if the direction of the antenna of the wireless terminal is not optimal for receiving Direction will cause the signal quality between the wireless terminal and the signal source to deteriorate, and the communication quality of the terminal device will be affected
