Abstract

Fractal contains an infinite number of scaled copies of a starting geometry. Due to this fundamental property, they offer multiband characteristics and can be used for miniaturization of antenna structures. In this chapter, electromagnetic transmission through fractal shaped apertures in an infinite conducting screen has been investigated for a number of fractal geometries like Sierpinski gasket, Sierpinski carpet, Koch curve, Hilbert curve, and Mowski fractal. Equivalence principle and image theory are applied to obtain the operator equation in terms of equivalent surface current density and is solved using Method of moments (MoM). Numerical results are presented in terms of transmission coefficient and transmission cross section for both parallel and perpendicular polarizations of incident wave which show the existence of multiple transmission bands.
