Title:
ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/227681
Kind Code:
A1
Abstract:
Provided is an electronic device. The electronic device comprises a base antenna, a dielectric body and a shell, wherein the dielectric body is arranged on the base antenna; the shell comprises a resonance area; a material, which is located in the resonance area, of the shell is a dielectric material; the surface of the dielectric body which faces away from the base antenna is connected to the shell located in the resonance area; and the dielectric body and the shell located in the resonance area together form a resonance body. The resonance body can be excited by the base antenna in a working state, such that the resonance body participates in radiation, thereby expanding the bandwidth of the base antenna. It can be understood that the base antenna forms a millimeter wave antenna by resonating with the resonance body. The electronic device provided in the present application is used to eliminate the negative influence of a glass back cover on the performance of an antenna.
