Design and Development of a Tapered Slot Vivaldi Antenna for Ultra-Wide Band Application
نویسنده
چکیده
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 ultra-wideband (UWB) from 3.1 to 10.6 GHz by using CST Software. In order to improve the bandwidth and the return loss characteristics of the emitted signal, UWB is discovered. The simulation results show that the return loss is better than -10dB within the preferred frequency range. Therefore the designed antenna will be useful for ultra-wideband application. Keywords— UWB, Microwave imaging, wireless communications, Ground Penetrating Radar, Remote Sensing, Phased Arrays, Tapered Slot Vivaldi Antenna.
