A Novel Reflectarray Antenna Combined with Double Layer FSS for RCS Reduction

Abstract

This paper examines the frequency selective surface (FSS) in the reflectarray antenna for reduction of radar cross section (RCS). A 12x12 novel reflectarray antenna with double layer FSS is used for verify RCS reduction. The double layer FSS structure is settled behind of the reflectarray antenna as a ground. FSS backed reflectarray antenna and ground plane backed reflectarray antenna is simulated on RCS performance. The simulation results show that double layer FSS structure is reduced RCS level between 2 GHz - 12 GHz when compared with ground plane backed reflectarray antenna. Gain and radiation performance of FSS backed and ground plane backed reflectarray antenna are compared to each other.
