Performance Improvement by New Integration Scheme of Radome-FSS-Antenna

In this letter, a novel FSS-radome is proposed based on a new integration scheme. Transmission, radiation and scattering characteristic of the proposed model are investigated and compared with the classical design of FSS-radome. Both the simulation and measurement results show that FSS radome based on the new integration scheme has high transmission efficiency within passband and keeps the radiation pattern of the antenna. Moreover, the proposed design can reduce the RCS in the axis direction of radome dramatically (about 28dB).
