A novel wide-band frequency selective surface with multiple transmission zeros and poles

Abstract

In this article, a novel frequency selective surface with multiple transmission zeros is proposed which works with one pass-band from 9. 7GHz to 12.2GHz(X-band) and two stop-bands from C-band to Ku-band. There are two zeros in each band so that the width and the rectangle coefficient of each band can be large enough. The FSS is achieved by two-layer periodic arrays of unit cells based on loop structure and Jerusalem cross. It works stable in different incident angles and polarizations and the insertion loss is less than 0.4dB.
