A Novel Semi-Fractal Shaped Antenna for UWB Applications

In this paper, we propose a semi fractal shapedmicrostrip-fed monopole antenna for UWB applications. The proposed antenna has a main circular ring with four smaller rings inside the main one as the radiating patch. The ground plane of the antenna that is priof the substrate, is in the shape of half an ellipse. The antenna size is 15×18×0.8mm3and operates over the UWB frequency range. Good nted on the other side Agreement is seen between the simulated and measured results. Antenna design and discussion about its performance will be presented in the paper.
