Design and Stimulation of New Fractal Antenna with Improved Return Loss at Various Frequencies for Ultra Wide Band Applications

Abstract: In this paper the design of micro strip feed ultra wideband fractal antenna under different resonance frequency. A single feed compact fractal antenna for multi band is demonstrated in this paper. Five iteration is introduced over the patch for reducing the resonant frequency. Four resonant frequencies at 1.95 GHz, 3.6 GHz, 4.8 GHz, and 6.4 GHz respectively are obtained for the proposed antenna. The experimental results of fractal antenna shows ultra wideband characteristics from frequency range of 1.8GHz to 6.5 GHz.CST software is used to design and stimulate the proposed antenna and extensive analysis of return loss is done for the same.The simple design of proposed antenna makes it suitable for application in UWB,C band and satellite communication.
