Design of an FP/EBG antenna with metamaterial PRS

Abstract

FP/EBG antennas have received intensive attention and large investigations during the last decade. The development of such structure opened the field for real industrial applications in the microwave domain, especially for the antenna design. In this paper we present an FP/EBG antenna operating around 2GHz. The structure consists of a Fabry-Perot Cavity composed of a ground plane, an air cavity and a Partially Reflecting Surface (PRS) made of SRR cells (Slot Ring Resonator). The simulation results show a directivity enhancement of about 4 dB. This structure can be used as directive antenna in communication systems.
