Document Type and Number:
WIPO Patent Application WO/2021/233131
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a multi-frequency dual-polarized antenna and an electronic device, which relate to the technical field of antennas and can effectively reduce the complexity of an antenna, reduce the processing cost and significantly reduce the space required for the antenna on the premise of achieving multi-band dual-polarized radiation. According to the specific solution, the antenna comprises a first radiator and a second radiator, which have rotationally symmetrical structures. The first radiator is provided with two feed ports which are 90° rotationally symmetrical with respect to the geometric center of the first radiator. The second radiator is ring-shaped, the first radiator is coplanar with the second radiator, the first radiator is arranged inside the second radiator, and an annular gap is provided between the first radiator and the second radiator.
