Abstract :
A compound frequency selective surface (FSS) with quasi-elliptic bandpass response is presented. The new FSS element comprises unit cells of two kinds of FSSs with one transmission zero. The FSS formed by this new element integrates the two transmission zeros of the original FSSs in one bandpass response curve and realises the quasi-elliptic filter response. Both theoretical and experimental investigations are carried out. Excellent agreement between simulation and measured results shows the validity of the theoretical analysis.
