Abstract
This paper describes the multiband behavior of a series of perturbed fractal Sierpinski gasket antennas. Sierpinski gaskets, with Periodic ratios of 0.5, 0.65, and 0.75 were fabricated and tested. Two methods are presented that improve the inherently poor input impedance match of the antenna with a 50 Omega port. Theoretical simulation is used to give an insight into the field distribution of the antenna as the perturbing ratio varies. Different properties and merits of the antenna due to perturbation were noted. These improved feeding methods will allow further flexibility to the application of these multiband antennas.
