Ultra WideBand (UWB) has a number of applications that make it attractive for a variety of applications such as microwave imaging, wireless communications, ground penetrating radars, remote sensing and phased arrays. This paper offered the design of a tapered slot Vivaldi antenna for ultra-wideband application using FR4 substrate which has relative permittivity of 4.4. The Vivaldi antenna is designed to cover UWB from 3.1 to 10.6GHz by using CST Software. In order to improve the bandwidth and the return loss characteristics of the emitted signal, UWB is discovered.
