Microstrip wideband antennas with different fractals geometries

This paper presents three novel microstrip antennas models using different fractal geometries. The radiators were developed by applying Cantor's comb, Sierpinski carpet and Sierpinski triangle, combined with the feed systems that enables large bandwidths operations. These radiators are very important in compact portable equipments construction. Experiment and simulated results 1GHz to 20GHz frequency range are presented, to compare the three models behaviors and performances.
