Title:
ANTENNA, ARRAY ANTENNA AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/124885
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are an antenna, an array antenna and an electronic device. The antenna comprises an antenna main body. The antenna main body is provided with a radiation aperture face, which is provided with at least one radiation aperture. The radiation aperture is provided with one or more conductive pieces, which divide the radiation aperture into a plurality of sub-radiation apertures. The sub-radiation apertures are arranged at intervals in a direction perpendicular to an electric field at the radiation aperture face, and are all located on the radiation aperture face, so that the energy density of the radiation aperture is subjected to weighted distribution by at least two sub-radiation apertures. Thus, the antenna changes from a traditional cylindrical wavefront to an approximately planar wavefront, thereby increasing the gain of the antenna. Therefore, when the antenna of the embodiments of the present application is manufactured, the cross section height and the size of the radiation aperture face of the antenna can be reduced. In addition, the size of each sub-radiation aperture in the direction perpendicular to the electric field is 0.3λ-2λ so as to guarantee that electromagnetic waves with a certain frequency can pass through the corresponding sub-radiation apertures.
