摘要：
This work proposes a graphene-based absorptive/transmissive metasurface (GATM) for antenna wideband radar cross-section (RCS) reduction. The GATM unit cell includes a graphene lossy layer and a bandpass frequency selective surface. The GATM acts as a superstrate on the top of the microstrip antenna. Due to the transmission window of GATM, it is possible to preserve the antenna's radiation performance. Simulation findings demonstrate that monostatic RCS from 1.52 to 10 GHz is reduced while keeping the antenna radiation performance unchanged.
