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 Design TM 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.
