Abstract：Active reconfigurable Frequency Selective Surface (FSS) using pin diode for the Radar Cross Section (RCS) reduction of antenna is proposed. The reconfigurable technology is applied to the FSS design. The reconfigurable FSS reflector is able to perform switch between band-pass FSS and band-stop FSS. The active reconfigurable FSS with pin diodes applies to the antenna reflector for the antenna RCS reduction, and the radiation performance of the antenna is preserved. Through the diode is on or off, the reconfigurable FSS reflectors are different states. It can contribute to the reconfigurable RCS reduction of dipole antenna under different working conditions. The simulated and measured results show the largest RCS reduction is more than 20dB, and the RCS reduction region is -60°≤θ≤+60°. The radiation performance of the antenna is preserved when the diodes are ON-state. The active reconfigurable FSS provide a good method to solve the conflict between the gain enhancement and the RCS reduction. The reduction band and the state of the RCS can be switched by pin diodes.
