Fractal Dual Band Antenna for WLAN Applications

Fractal antenna, as name concerns, uses fractal i.e. structure does not change and repeat it when large focus has created upon it. This repetition feature of this antenna provides a great flexibility that it can be designed and can used in different frequencies. These antennas gives a finite area of coverage but the diameter of perimeter becomes infinite. Fractal antenna is used in most of the traditional and innovative applications today. In antenna engineering fractal geometry is very useful for performance improvement, in terms of gain and other things. Fractal antenna gives high performance with high variation in the size of its structure. This paper demonstrates an optimized and compact printed dual band fractal antenna suitable for WLAN applications. The proposed antenna works on 2.4GHz and 5.2 GHz. Simulation results show that the proposed design gives improved performance in terms of return loss and gain.
