摘要：A Simulation of a Vivaldi antenna for ultra-wide band applications is presented in this paper. Vivaldi antenna also known as tapered slot antenna belongs to the end fire travelling wave antennas. It consist of a symmetrically etched slot in the ground plane with a dielectric substrate placed over it.This antenna operatesin large frequency range and is of low cost. An antenna with length and width of 50mm*68.5mm is designed and simulated. A satisfactory gain of 6.7 dB with a large bandwidth of 2.6-9.3 GHz using HFSS 14.0 version is obtained
