The basic circular monopole antenna exhibits a 10 dB return loss bandwidth over the entire frequency band, the paper proposed a modified version of simple circular monopole antenna for WPAN application. The antenna offers excellent performance in the range of 2-12 GHz.. The antenna is designed on FR4 substrate and fed with 50 ohms micro strip feed line. The antenna is suitable for operating frequency of 7 GHz. It is shown that return loss of the antennas at 7 GHz is better than -10 dB and VSWR obtained is less than 2. Proposed geometry is design and simulated using HFSS11 Details of the proposed antenna design and measured results are presented.
