Abstract: This paper describes the design of Ultra Wide Band (UWB) antenna suitable for upper UWB frequency applications. In this context, three UWB antennas are designed: the first is with circle slot in a square, second is with triangle slot in a square and the third is with G shaped elements. The antenna element with small size of 8 x 8 mm2 is designed for UWB applications. The antenna element is fed through a 50 ohm microstrip line (MTL) and a thin strip is provided at the end of the MTL to provide impedance matching. It is printed on FR4 - epoxy substrate. The output is simulated on Ansoft HFSS (High Frequency Structure Simulator). The Parameters like return loss and bandwidth is discussed. From these three antennas, G shape antenna gives more return loss (S11) of -21.50dB compared with other two.
