Characterization of the koch fractal hexagonal loop frequency selective surface for X-band application

Abstract

This paper presented the bandstop Koch fractal embedded hexagonal loop frequency selective surface (FSS) for the X-band application. The simulated transmission coefficient response () had been obtained by using CST software. The surface current distribution and the electric field density are illustrated to explain in detail the of the fractal based FSS structure. The proposed structure is highly insensitive towards angular stability and also polarization independent up to . The parametric analysis on the effect of the periodicity, width, and height of the fractal FSS structure on the has been illustrated and discussed thoroughly.
