Improving stop-band properties of frequency selective surfaces with Koch fractal elements
Design and experimental investigations are presented for a cascaded frequency selective surface (FSS) with perfectly conducting Koch fractal patch elements. The work was developed in two steps. In the first step two Koch fractal FSS screens were designed using the software Ansoft Design¿ and several prototypes were built. In the second step these FSS screens were cascaded and separated by an air gap layer to improve the bandwidth behaviour. The structures are cascaded using Teflon spacers and screws to obtain the air gap. The FSSs were built on a RT-Duroid 3010 substrate. Good agreement was observed between simulated and measured results.
