Design and Development of a Novel Fractal Antenna for Wireless Applications

An innovative concept is utilized to develop the fractal antenna by coalesce the Koch prefractal and meander line. This fractal antenna is proposed for multistandard wireless applications. The shape and dimensions of the proposed antenna are chosen to obtain the multiband behaviour as well as miniaturized structure. Initially two different fractal concepts have been chosen through previous research and merged them to obtain more than two resonant frequencies. The proposed design characterizes four bands at resonant frequencies 2.5 GHz, 6.4 GHz, 7.2 GHz and 8.15 GHz with a return loss of -12.05 dB, -16.68 dB, -14.87 dB and -26.51 dB respectively. This design also represents VSWR between the required range of 1 to 2 for the presented resonant frequencies with an appropriate value of gain in dB. The antenna is analysed with Ansoft HFSS-13.0 electromagnetic field solver.
