In this paper a microstrip-fed planar monopole antenna has been proposed for wideband applications. The proposed antenna is fabricated onto an inexpensive FR4 substrate with an overall dimension of 18×16 mm². Simulation is performed by using the CST Microwave Studio software. the results show that the antenna achieved an UWB impedance bandwidth (S11< -10 dB) ranges from 5.54 GHz to 39.34 GHz (160.95%).Antenna performance parameter such as return loss, voltage standing wave ratio (VSWR), gain, directivity and radiation patterns of proposed antenna have been analyzed.
