A Compact Super Wideband Monopole Antenna Design using Fractal Geometries

A compact monopole antenna using fractal geometries is proposed for super wideband (SWB) application. The proposed antenna has a compact size of 22 x 33.4 mm and is designed using MOM based Full Wave Electromagnetic Simulator IE3D. Parametric studies have been performed to show the effect of various antenna parameters. The proposed antenna is able to achieve super wide bandwidth ranging from 3 GHz to 26 GHz with measured peak gain variation from 1.9 to 7 dBi and very good radiation pattern. The proposed antenna is fabricated and measured to demonstrate the performance characteristics. Simplicity, compactness and stable radiation pattern made the antenna useful for UWB and higher frequencies applications.
