Abstract

The embodiment of the invention relates to the field of communication, in particular relates to an antenna control system and method and a mobile terminal. The system comprises an antenna and a control module, wherein the antenna comprises a first antenna part and a second antenna part which are symmetrically distributed, the first antenna part and the second antenna part respectively has various working states corresponding to various working resonant frequencies, the control module comprises an antenna working state acquisition sub-module and a control sub-module, the antenna working state acquisition sub-module is used for acquiring a first working state of the first antenna part, the control sub-module is used for adjusting a second working state of the second antenna part according to the first working state, so that the difference value between the working resonant frequency of the first antenna part and the working resonant frequency of the second antenna part is smaller than a set threshold value, antenna energy is more uniformly distributed at two sides of the antenna, left/right antenna switching is not needed to be performed according to an actual application scene of the mobile terminal, and the technical effect of balancing a left head and hand function and a right head and hand function of the antenna is achieved.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to an antenna control system, method and mobile terminal. Background technique [0002] Reference figure 1 As shown, among the antenna technologies currently used in mobile terminals, common ones include monopole, inverted F-shaped antenna (IFA), loop antenna (LOOP), etc. The antenna feed is often placed in The corner on the left or right side of the mobile terminal is the single resonant arm antenna design. However, because the single resonant arm antenna resonates on a single branch on the left or right side, the antenna energy is too concentrated on the branch, which makes the electric field strength difference between the left and right sides of the mobile terminal very large, and the antenna branch that is biased to the head and hand side absorbs The loss will increase significantly, leading to a big difference in the performance of the head or hand. [0003] In the related art...
