A novel conformal multiband antenna design based on fractal concepts

We present a novel conformal multiband antenna design, based on fractal concepts, for application at three different frequencies in this paper. Although a whole host of conventional fractal type monopole and dipole configurations have been designed in the past, they are not well suited for conformal applications. In this paper we describe a Sierpinski gasket type of fractal configuration, printed on a dielectric substrate backed by a ground plane, and propose a novel approach to enhancing its multiband performance in terms of impedance matching characteristics as well as radiation patterns at three operating frequencies.
