Broadband AMC Surface for Radar Cross Section Reduction

A broadband artificial magnetic conductor (AMC) surface is designed for radar cross section (RCS) reduction in this paper. The proposed AMC configuration is composed of two different AMC unit cells, which contribute to destructive phase difference (180°±37°) over a broad frequency band. With fan-type arrangement of the two AMC units, 77.9% frequency bandwidth (12.3-28GHz) of -10 dB RCS reduction compared to perfect electric conductors (PEC) sheet has been obtained. Simulation results show that this AMC configuration may achieve potential application on low-RCS platforms.
