Implementation of Fractal Geometry to Enhance the Bandwidth of CPW Fed Printed Monopole Antenna

ABSTRACT

In this article, implementation of a plus shaped fractal geometry is proposed to broaden the impedance bandwidth of a co-planar waveguide (CPW) fed microstrip patch antenna. Compared to the reference antenna, the bandwidth of plus shaped fractal antenna is more than double (56% from 4.56 to 7.92 GHz covering most of the C-band) and size has been reduced by 11.36 %. Further, analysis of dimensional parameters of the co-planar ground plane has been examined critically in order to investigate its effect on antenna performance. Experiments have been performed on the fabricated antenna and the obtained results show a good agreement with the simulated results.
