摘要：
A switchable reflector which can switch reflection level using pin diodes for the vertical polarization and absorb for the horizontal polarization was proposed. The vertical polarized reflection coefficient was switched -29 dB with OFF-state diodes and -0.5 dB with ON-state diodes, and horizontal polarized one was less than -15 dB at 9 GHz. The reflector with ON-state diodes was applied to an antenna reflector of a dipole antenna and comparable radiation pattern to that with a metal reflector was obtained at 9 GHz. Therefore it can contribute to dual-polarized antenna RCS reduction at operating frequency without degrading antenna performance.
