A wideband planar monopole antenna by CPW fed to circular patch is presented for WLAN, WIMAX and various applications. This antenna has very compact in size, has width 35.3mm,length 40mm and height 1.52mm fed with the coplanar waveguide of 50ohm microstrip line where ground is reduced sized, below the substrate. The proposed antenna covers the frequency range of 2.47 GHz to 7.181 GHz range which has impedance bandwidth of around 4.7 GHz and return loss dip is -20dB. The gain is around 2.58 dB and directivity of 2.91dB.
