There are many efforts done by the several researchers around the world, to combine fractal geometry with electromagnetic theory have led to a world of new and innovative antenna designs. In this report, we provide a research on the fractal antenna in the field of fractal antenna engineering. The research for the fractal antenna is focused in the two areas: the first deals with the design of fractal antenna elements, and the second deals with the applications of the fractal antenna. From the previous research it was shown that Fractals have no characteristic size, and are generally composed of many copies of themselves by different scales. This unique property of the fractal antenna plays a very significant role in the size reduction and enhancement of bandwidth.
In this paper, we used Meta material to attain the better results and the antenna can be used for ultra wide band applications. By the use of the meta material antenna attains a impedance bandwidth of 98.6%.the value of the mutual coupling is observed to be -25dB and the radiation pattern shows us that the antenna can be used for the ultra wide band applications. Antenna attains a diversity gain of greater than 9.97dB and ECC is less than 0.06. The applications of this antenna cover WLAN, WIMAX, UWB applications etc.
HFSS software is used for the simulation and FR4 epoxy material is used to design the substrate.
