Abstract

In this article an ultra wideband hexagonal shaped double printed circular inscribed dipole antenna is presented with size miniaturization. For miniaturization fractal geometry is introduced. For simulation frequency spectrum from 2.99 to 10.45 GHZ(111%) is covered by the proposed antenna and in measurement it is in between 3.04 to 10.49 GHZ(110%) by using linearly tapered micro strip feedline instead of stepped feedline. As a result the volume and area of the antenna is miniaturized up to 35.89% and 16.67% severally as compared to other ceremonious UWB dipole antenna. The gain observed for simulation is 3.31 dBi and 2.06 dBi for measurement. Impedance bandwidth achieved, is 110%(3.04- 10.149)GHZ. Remarkable agreement is found between measured and simulated results.
