Design of a Wide-Band Waveguide-Fed Aperture Antenna Using FSS

In this paper a novel wideband, high gain, and low profile antenna has been proposed. A waveguide mounted to a ground plane incorporating with a FSS (Frequency Selective Surface) has been proposed to enhanced bandwidth and gain of this kind of antenna. The waveguide feeds the antenna which is composed of the aperture mounted on an extended conducting plane, together with a FSS as a superstrate, which is placed over the aperture. This antenna has been designed for X-band application. The proposed structure has been simulated with HFSS and maximum gain of 13.22 dB, and bandwidth of 40% has been achieved. Total profile of this antenna is 1.32λ02.
