Microstrip printed wide slot antenna with a fork like tuning stub for bandwidth enhancement is proposed in this paper. By applying fork like tuning stub to the microstrip wide slot antenna instead of line feed, it is experimentally found that operating bandwidth can be enhanced. Experimental results indicate that the impedance bandwidth, defined by -10dB return loss, of the proposed wide slot antenna can reach operating bandwidth of 3.1 GHz at operating frequency about 2 GHz which is 6 times greater than conventional wide slot antenna.
