Miniaturization of frequency selective surfaces using fractal Koch curves

This article presents a proposal for frequency-selective surfaces (FSSs) miniaturization. The FSSs are made up of a 2D periodic array of metallic Koch fractal element. The FSS prototypes were designed using the software Ansoft DesignTM and several prototypes were built. The FSS were built on a RT-Duroid 3010 substrate. All the built FSS obtained a good agreement with simulated results. We obtained a reduction of up to 50% of area with the use of fractal Koch curves. © 2009 Wiley Periodicals, Inc.
