Design of an Ultra Wideband Fractal Antenna for Microwave Applications
In this paper, a compact fractal monopole antenna for ultra wideband application is proposed with microstrip feed technique. The fractal structure generates multiple frequencies and increases the bandwidth of the patch antenna. Fractal antenna gives better performance in terms of return loss, efficiency and directivity. The proposed antenna is designed on an inexpensive FR4 Epoxy substrate of thickness 1 mm and a dielectric constant of 4.4. Theoretical investigations done by Ansoft Designer reveal that the structure resonates at 8.16GHz and has an ultra wide bandwidth of 2.8GHz.
