Abstract

A Cassegrain-type metamaterial antenna, includes: a metamaterial main reflector having a central through-hole, a feed source disposed in the central through-hole, and a sub-reflector disposed in front of the feed source, where an electromagnetic wave radiated by the feed source is emerged in a form of a plane wave after being reflected by the sub-reflector and the metamaterial main reflector in sequence; the metamaterial main reflector includes: a first core layer and a first reflection layer disposed on a rear surface of the first core layer, where the first core layer includes at least one first core layer lamella, and the first core layer lamella includes: a first base material and multiple first conductive geometric structures disposed on the first base material; and a far focus of the sub-reflector coincides with a phase center of the feed source.
