Abstract: Self similar arrays have frequency independent multi band characteristics. This paper presents the design of fractal antenna based on the Koch curve geometry. The antenna has been optimized to operate in multiple bands between 3-8 GHz and efficiency of 85 percentages with a peak gain of 4db. Design and analysis of fractal antenna is done by using CST software. The results show that the designed Koch Curve antenna is suitable for wireless applications.
