Abstract

The invention provides an antenna circuit, a control method and a device of a mobile terminal. The antenna circuit comprises at least two antennas, wherein, each antenna is respectively connected withan antenna tuner; a radio frequency circuit electrically connected to a first antenna of the at least two antennas; a power detection module connected with a radio frequency circuit; a receiving path, wherein each of the at least two antennas other than the first antenna is connected to the receiving path through a switching switch, and each switching switch is connected to a power detection module; a controller respectively connected with the power detection module and the antenna tuner. Therefore, the scheme of the invention solves the problem that the isolation between the multiple antennas is too low and the antenna efficiency is poor.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to an antenna circuit, a control method and a device of a mobile terminal. Background technique [0002] Currently, mobile terminals need to support more and more frequency bands. Therefore, in order to improve antenna efficiency, most terminals adopt antenna division technology, resulting in an increase in the number of antennas. In addition, with the continuous evolution and iteration of communication technology, Multiple-Input Multiple-Output (MIMO) technology is gradually introduced into commercial use, and terminal support for MIMO technology is the mainstream trend, from 2X2MIMO to mainstream 4X4MIMO, or to N X N MIMO on the back. [0003] Among them, the fixed shape of the terminal determines that the antenna space is limited, which makes the dense antenna distribution lead to a series of problems, such as the low isolation between MIMO antennas affects...
