Abstrakt: In this article, a compact, dual‐band, dual‐polarized band pass single‐layered frequency selective surface (FSS) structure with stable performance in wide incident angles is designed and fabricated. This structure is designed with a new proposed approach which is the combination of miniaturized‐element band stop FSS and high pass grid FSS. For this purpose, a new compact band stop structure is introduced and miniaturized by adding vertical metalized holes (vias) in the substrate as additional capacitive. A WLAN band stop FSS is designed also as an example of the proposed miniaturized‐element. Then, this band stop FSS is combined with a simple high pass grid structure to design the proposed band pass FSS. The circuit models of these FSSs are also extracted to achieve better description of the structures and combination idea. The dimensions of the final designed compact band pass FSS structure is 0.048λ × 0.048λ where λ is the free space wavelength of the first resonance frequency. The fabrication results of this FSS which works at WLAN bands are in good agreement with the simulation ones which prove the design approach. [ABSTRACT FROM AUTHOR]
