Design of Dual Band Dual Polarized Active FSS

This paper presents a dual band dual polarized active frequency selective surface (AFSS) with the bandpass response to operate over 1.99-6.11 GHz and 11.0-14.52 GHz bands. The structure has a −3dB wide fractional band bandwidth (FBW) of 75.8% and 28.16% bandwidth in these two bands, respectively. Tuning ratio is defined as the ratio of the resonant frequencies corresponds to the maximum and minimum biasing voltages and in these two bands, it is 3.07 and 1.32, respectively. Additional results will be shown during the symposium.
