Abstract
Disclosed is a Cassegrain microwave antenna, which comprises a radiation source, a first metamaterial panel used for radiating an electromagnetic wave emitted by the radiation source, and a second metamaterial panel having an electromagnetic wave convergence feature and used for converting into plane wave the electromagnetic wave radiated by the first metamaterial panel. Employment of the principle of metamaterial for manufacturing the antenna allows the antenna to break away from restrictions of conventional concave lens shape, convex lens shape, and parabolic shape, thereby allowing the shape of the Cassegrain microwave antenna to be panel-shaped or any shape as desired, while allowing for reduced thickness, reduced size, and facilitated processing and manufacturing, thus providing beneficial effects of reduced costs and improved gain effect.
