In this paper, Multi Band in Ultra wide band monopole patch antennas is proposed. These newly simulated structures are proposed for fabrication. The antennas are suitable for operating frequency of 3.5GHz and 7.5 GHz in Wi Max and ISM band it is shown that return loss of the antennas at 3.5 GHz and 7.5 GHz is better than -10 dB. The VSWR obtained is less than 1.5 the patch antenna is found to have the compact size and more bandwidth. The return loss value of first band is -39.68 dB and for second band are 18.0 dB. With radiation efficiency 94% and Antenna efficiency 80% calculated using HFSS-13 simulation software. The measured results are also calculated with Vector Network analyzer.
