In-Band Radar Cross Section Reduction of Slot Array Antenna
IEEE Access, 2018 A slot array antenna is proposed for both in-band and out-of-band radar cross section (RCS) reduction. The presented slot array antenna is covered by the superstrate consisting of a polarization rotation reflective surface (PRRS).
