Square Spiral Curve Fractal Antenna for Multiband Wireless Communication

The design of spiral curve fractal antenna for multi frequency application is proposed in this paper. Designed shape is based on the principle of fractal geometry. The given antenna fallows both the properties of fractal i.e. self-similar and space filling in order to miniature the antenna size and use one antenna for more than one frequency band respectively. The proposed antenna used up to three iterations. It has been observed from the result that as we increase the number of iteration the antenna show multiband characteristics. Also the return loss, VSWR, current distribution, gain and direction pattern shows that this antenna is more applicable for multi frequency applications, especially in the range of 6 GHz to 9 GHz. The Ansoft HFSS software is used for the simulation purpose.
