Abstract
Based on a polarization-dependent artificial magnetic conductor (AMC), a windmill-formed reflector is designed and applied to a circularly polarized patch antenna to reduce the radar cross section (RCS) and to improve the radiation properties of the antenna at the same time. Simulation and measurement results show that the proposed antenna bears an in-band RCS reduction for 10dB over a bandwidth of 30% for both polarizations. The 3dB axial ratio (AR) bandwidth is extended largely with gain improved compared with the reference antenna.
