Title:
ANTENNA, ANTENNA ARRAY, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/082994
Kind Code:
A1
Abstract:
Embodiments of the present application provide an antenna, an antenna array, and an electronic device. The antenna comprises a radiation patch layer, an annular metal layer, a first metal layer, and a feed unit. The radiation patch layer comprises four radiation patches distributed in an array of 2*2. When the feed unit feeds power, in a clockwise arrangement direction of the four radiation patches, a first phase difference is present between electrical signals on two adjacent radiation patches so as to realize circular polarization of side radiation characteristics. The annular metal layer is arranged opposite to a peripheral part of the radiation patch layer and is coupled to the radiation patch layer. The first metal layer is provided with a plurality of metal columns, and the plurality of metal columns are electrically connected to the annular metal layer to form a fence-shaped coupling capacitor column, so that the antenna can have a low profile, and miniaturization of the antenna can be facilitated. The antenna provided by the embodiments of the present application can have the characteristics of low profile and circular polarization, and can be applied to electronic devices.
