Abstract :
Planar periodic metallic arrays behave as artificial magnetic conductor (AMC) surfaces when placed on a grounded dielectric substrate and they introduce a zero degrees reflection phase shift to incident waves. A novel gradually concentric ring arrangement AMC (GCRA-AMC) applied to the broadband RCS reduction is presented. The simulated results show that the radiation performance of antennas is preserved when the GCRA-AMC is used. The RCS of the antenna with GCRA-AMC has been considerably reduced in a broadband.
