Keywords:
Frequency Selective Surface (FSS), Partially Reflecting Surface (PRS), Resonant Cavity Antenna (RCA)Abstract
In this paper a wideband, high-gain, and compact design of an aperture antenna has been proposed. In the proposed antenna a patch type frequency selective surface (FSS) as a superstrate has been placed in front of a rectangular aperture, mounted to a conducting ground plane. The proposed simple 3×3 patch type FSS has considerably enhanced the antenna performance, including the gain and the bandwidth concurrently. The proposed structure has been simulated to validate the obtained results. The maximum gain of 16.03 dB and 3-dB gain bandwidth of 19.7% (14.25–17.35 GHz) has been achieved.
