Title:
ANTENNA AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/044956
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications, and provides an antenna and a communication device, for solving the problems of low antenna radiation efficiency and the like. The antenna provided by the present application comprises a main reflecting surface, a sub-reflecting surface and a feed source. The main reflecting surface and the sub-reflecting surface are oppositely arranged. The feed source is provided with a plurality of radiation ports, and electromagnetic waves emitted by the plurality of radiation ports are reflected by the sub-reflecting surface to the main reflecting surface. The sub-reflecting surface comprises a plurality of curved surfaces, and the virtual focuses of the plurality of curved surfaces do not overlap. The plurality of radiation ports are located in an area formed by the plurality of virtual focuses. In the antenna provided by the present application, the sub-reflecting surface can provide a plurality of virtual focuses at different positions to adapt to radiation ports at different positions, so that electromagnetic waves generated by the radiation ports at different positions are efficiently reflected, and thus the radiation efficiency of the antenna can be effectively ensured.
