摘要：

A design of ultra-wideband (UWB) Vivaldi antenna is reported. In this antenna, elliptical taper has been used to design the proposed antenna. The antenna is shaped by subtracting two ellipses that have different dimensions, and then limited by a rectangle. Impedance bandwidth covers a rather wide spectrum from 2 GHz to over 14 GHz with average gain of 6.6 dBi over the working frequency band. Measured results of elliptical Vivaldi antenna in the entire UWB frequency range reveal a transfer function with flat level, and a group delay with variations less than 0.5 ns. The simulation results agrees with the results acquired by measurement.
