This paper presents a new three-dimensional (3-D) band-pass frequency-selective structure (FSS) with controllable multiple transmission zeros. The proposed FSS consists of a simple array of vertical two-dimensional (2-D) microstrip lines and “T-type” inserted metallic plates, which can be seen as a combination of a 3-D dual-band band-stop FSS and a 3-D bandpass FSS. Based on this combined structure, the operating principle of the proposed FSS is explained and discussed. Simulated results demonstrate that the FSS exhibits wide passband with high selectivity and stable frequency response under a large variation of the incidence angle.
