A Compact Printed Antenna for WiMAX Application

A single feed compact microstrip antenna is proposed in this paper. Two L slits are introduced at right side of the patch. For the proposed antenna resonant frequencies are obtained at 3.48 GHz, 4.34 GHz and 5.65 GHz with bandwidth of 19 MHz, return loss - 20.2 dB, 42.6 MHz, return loss -30.5 dB and bandwidth of 39.2 MHz, return loss -20.2 dB respectively. The size of the antenna has been reduced by 66 % when compared to a conventional microstrip patch.
