Antenna and communication device

Abstract

This application provides an antenna. The antenna includes a primary reflector, a secondary reflector, and a feed. The primary reflector and the secondary reflector are disposed opposite to each other, the feed has a plurality of radiation ports, and electromagnetic waves emitted by the plurality of radiation ports are reflected by the secondary reflector to the primary reflector. The secondary reflector includes a plurality of curved surfaces, virtual focuses of a plurality of curved surfaces do not coincide, and the plurality of radiation ports are located in an area formed by a plurality of virtual focuses. In the antenna can take account of a plurality of radiation ports at different positions, so that electromagnetic waves generated by the radiation ports at different positions are efficiently reflected. In this way, radiation efficiency of the antenna can be effectively ensured.
