The objective of the project is to design and simulate the planar monopole antenna for UWB applications. The base of the proposed antenna is a diamond-shaped patch (DSP) that covers the ultra wide band (UWB) 3.1–10.6 GHz frequency range. It is shown that by removing the centre part of the DSP antenna, without distorting the UWB behavior. This will not affect the dimension of the base antenna. The used substrate is FR4 with relative permittivity of 4.4 and thickness of 1mm.The designed simple DSP - UWB antenna has a substrate size of 16*22mm2and covers the frequency band 3.1–10.6 GHz which includes UWB. The antennas have omnidirectional and stable radiation pattern. Hence, a rectangular shaped ground plane is designed and will be simulated using ANSOFT-HFSS. The parameters such as return loss, VSWR and radiation pattern are taken
