PENTAGONAL FRACTAL ANTENNA FOR UWB APPLICATIONS WITH BANDWIDTH ENHANCEMENT

This paper,presents design of microstrip patch antenna at frequencies 3 .1 to 10.6 GHz. Further by introducing fractal concept to the pentagonal - shaped microstrip antenna is designed .The Ans oft HFSS finite element electromagnetic computer package was used to model,simulate and analyze pentagonal fractal antenna that operates at UWB frequencies. From space - filling property of f ractal geometry,this antenna gives lower resonant frequencies,it is found that as iteration and iteration factor increases,the resonant frequency of this patch antenna decreases. The material used for substrate is FR4 with relative permittivity of 4.4 and thickness is about 1.53 mm . Microstrip line is used to feed t he antenna. HFSS V13 software is used to design and simulate the proposed antenna. The results show that the proposed antenna offers good performance in multi band frequencies which is suitable for wireless point to point applications.
