Compact size ultra wideband Hexagonal Fractal antenna

A compact size ultra wide-band coplanar waveguide (CPW) fed, fractal antenna is presented. A rectangular slot antenna is excited by a 50Ω-CPW with a fractal patch. The antenna was studied experimentally regarding impedance bandwidth, radiation patterns and gain. For the proposed antenna, the -10 dB return loss bandwidth could reach 7.45 GHz (2.85 GHz - 10.3 GHz). Details of the antenna design, simulation and measured results on the return loss and the E and H-plane radiation pattern of the proposed antenna are presented.
