A Low-RCS Dual-band Dual-polarized Antenna Based on Absorptive Frequency-Selective Reflector
This paper presents a low radar cross-section (RCS) dual-band dual-polarized antenna designed based on absorptive frequency-selective reflector (AFSR). The AFSR is composed of a dual-band dual-polarized bandstop frequency selective structure (FSS) and an absorber under the FSS. The bandstop FSS element is designed using cross-frame and square ring to realize dual-band dual-polarized operation. The reflection frequency band of AFSR coincides with the operation band of the antenna. The simulation results indicate that the AFSR-backed antenna system has a remarkable reduction of out-of-band RCS and relatively consistent radiation performance compared with the PEC-backed antenna.
