Antenna module and electronic device

Abstract

The application relates to an antenna module and an electronic device. The antenna module comprises a first antenna unit and a second antenna unit. The first antenna unit comprises a first radiation branch and a ground tuning circuit. The first radiation branch can be connected to a first feed signal. The second antenna unit comprises a second radiation branch. The second radiation branch can be connected to a second feed signal. When the second feed signal excites the second radiation branch to work in a first resonant mode to transmit a first frequency band signal, the first feed signal excites the first radiation branch to generate a surface current to transmit a second frequency band signal. The frequency ranges of the first frequency band signal and the second frequency band signal at least partially overlap. When the second radiation branch generates an induced current on the first radiation branch, the ground tuning circuit at least adjusts the current direction of the radiation branch between the first ground end and the second ground end to be the same as the current direction of the first resonant mode. The radiation efficiency of the second antenna can be improved, the isolation can be solved, and the antenna performance can be improved.
