Abstract

In this paper, an active frequency selective surface (AFSS) with tunable frequency passbands is proposed. The AFSS structure is composed of three metallic layers that separated by two thin dielectric substrates. The tunable passband characteristics can be achieved by embedding PIN diodes on the top and bottom metallic layer. By switching the on-off state of PIN diodes on the top and bottom layer, the resonant frequency will change, thus realizing the passband tunability. Meanwhile, the AFSS structure has good angular stability in the large oblique incidence.
