Abstract

In this paper, a novel double-layer frequency selective surface (FSS) is proposed. Each layer consists of two semi-circle fractal elements put into a circular structure on a dielectric substrate. Simulation by CST MICROWAVE STUDIO^® is conducted to testify the characteristics of the FSS. The results show that the novel structure has three resonant frequencies in the frequency band 0-30GHz with relatively high impedance, and when illuminated by waves of different incident angles and polarizations the structure performs good stability. In addition, effects of the structure´s parameters on the transmission performances are discussed, which provides theoretical basis for practical applications.
