Abstract

A novel frequency selective
surface (FSS) configuration in the reflectarray antenna is proposed for
reduction of radar cross section (RCS) level in this work. Double-layer FSS
structure is located behind the reflectarray antenna as a ground. A 9



















9 elements FSS with variable size patches has same
geometry with the reflectarray antenna. The RCS reduction performance of
reflectarray antenna both ground plane backed and FSS backed is compared. The
results of simulation are obtained by using CST Microwave Studio. The
simulation results show that RCS level of FSS backed reflectarray antenna is
reduced both in-band (8-12 GHz) and out-of-band (2-7 GHz and 13-18 GHz). In the
literature, RCS reduction of reflectarray antenna with FSS structure has only been
achieved out-of-band. Furthermore, the gain and
radiation performance of the ground plane backed reflectarray antenna and FSS
backed reflectarray antenna are compatible with each other.
