Abstract :
Design and development of a novel, circularly polarized thin radar absorbing material (RAM) with 10 dB (minimum) Radar Cross Section Reduction (RCSR) from 6 to 14 GHz. and 15 dB from 8 to 12 GHz. using resistive circular patch frequency selective surfaces (FSS) is presented in this paper. The design is analyzed using the full-wave simulation software, HFSS v15. The size of the assembled prototype panel RAM is (280 mm × 280 mm). The total thickness of RAM is 6.2 mm. The weight of panel RAM is 92 gm. Monostatic radar cross section (RCS) measurements are carried out in microwave anechoic chamber to verify the performance. Simulation and experimental results agree closely.
