Design of conformal multiband antennas based on fractal concepts

In this paper we present some novel designs for conformal multiband antennas, based on fractal concepts, for application at three different frequencies. Although a whole host of conventional fractal type of 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. © 2003 Wiley Periodicals, Inc.
