Abstract

A novel reduced size three band Koch Pentagonal fractal antenna is presented. The proposed antenna uses pentagonal shape for the basic fractalization combined with inner sides etched with Koch fractal pattern of the first iteration providing reduction in the overall size of the antenna. For higher order of iterations, more size reduction is achieved, producing equal number of radiation bands. Optimization is done for achieving radiations in the S, C and X bands. Ansoft HFSS, CST Microwave Studio and Solid Works are used for the 3D Modeling, S11 frequency optimization and radiation pattern calculations. The proposed third iteration fractal configuration is fabricated on Rogers RT5870, and measured results are presented. Size reduction up to 43.26 percent in terms of its overall size and 75.18 percent in terms of copper cladding remaining is achieved for the third iteration proposed fractal antenna in comparison to pentagonal patch antenna operating in the first resonant frequency band.
