Abstract
Cavity backed slot antenna systems and methods are provided. The systems include a frequency selective surface, a housing containing a cavity, and a feed structure between at least portions of the frequency selective surface and the cavity. The frequency selective surface can be embedded in a non-conductive slot in a first ground plane. The cavity can contain a space filler. Embodiments of the present disclosure provide an antenna with a relatively wide bandwidth and a relatively small antenna element.
