Abstract: In this paper a microstrip-fed planar monopole antenna has been proposed for wideband applications. Three monopole antenna have been designed and analyzed for improving antenna performance parameters. Antenna performance parameter such as return loss, bandwidth, voltage standing wave ratio (VSWR), gain, directivity and radiation efficiency of proposed antenna have been analyzed and compared with each other. As a simulation tool CST Microwave Studio 2012 has been used. Proposed antenna showed the resonance at 6.46 GHz and 10.49 GHz. At these points return loss founded as -19.77 dB and -13.45 dB respectively. Obtained bandwidth of these points at -10dB are 20.14% and 5.79%. Later comparison of performance parameters have been done.
