Abstract

A switchable reflector using pin diodes for the radar cross section (RCS) reduction of an antenna reflector was proposed. The reflection coefficient of the proposed reflector was able to be switched between less than -25 dB with OFF-state diodes and more than -0.8 dB with ON-state diodes around 5 GHz. The proposed reflector with ON-state diodes was applied to a dipole antenna reflector and gave equivalent radiation pattern to with a metal reflector. It can contribute to the antenna RCS reduction at the radiation frequency without degrading antenna performance.
