Abstract
This paper describes the design and behavior of a Fabry-Perot Cavity (FPC) antenna system with split beam in the near-field and decreased beamwidth of the far-field pattern. The FPC antenna system is a coplanar waveguide (CPW)-fed slot antenna with 9 × 27 rectangular aperture unit cells in the frequency selective surface (FSS) oriented in horizontal and vertical directions. The far-field response has 3dB beamwidth of 21° and gain of 12.84 dBi at 11.2 GHz.
