Abstract

In this paper a hexagonal shaped monopole fractal antenna for UWB application is designed. The proposed fractal-like geometry is implemented on a microstrip fed planar hexagonal monopole antenna. The iterated hexagonal fractal patch and modified ground plane are employed to achieve the desired wideband characteristics. The simulated results show that the antenna has a good performance with 10dB-return loss in the frequency range 2.64-6.96GHz that results in a fractional bandwidth (FBW) of 90%. A notch is also achieved by introducing slits in ground plane. The simulated return loss, radiation patterns and gain of the proposed antenna are presented.
