ELECTRONIC DEVICE

WIPO Patent Application WO/2022/127896

A1

Provided is an electronic device, which relates to the technical field of electronic devices, and can improve the radiation efficiency of an antenna in the electronic device. The electronic device comprises a reference ground layer, a first radiator and a second radiator, wherein the reference ground layer has a first edge, and a second edge and a third edge which are respectively connected to two ends of the first edge; the first radiator is provided with a first grounding point and a first feed point, which are arranged at an interval, with the first grounding point being electrically connected to the reference ground layer; the second radiator is electrically connected to the first edge of the reference ground layer, an end section of the second edge that is connected to the first edge, or an end section of the third edge that is connected to the first edge; the electrical length of the reference ground layer in a first direction is a 1/2 wavelength of a main resonant band of the first radiator; and a parasitic resonance band generated when the second radiator feeds a radio frequency signal at the first feed point is lower than a main resonant band generated when the first radiator feeds a radio frequency signal at the first feed point. The electronic device provided in the present application is used for a communication system.
