چکیده :
An ultra-wideband (UWB) Vivaldi antenna is reported. In this antenna, dual tapering has been used to design the antenna. The antenna is shaped by subtracting a circle from an ellipse, and is limited by a rectangle. Bandwidth of impedance spread out from 2.3 GHz to over 15 GHz with mean of maximum gain of 7.3 dBi. Measured results of dual tapering Vivaldi antenna in the entire UWB band frequency reveal a transfer function with flat level, and a group delay with variations about 0.3 ns. Finally, results of simulation and measurement have a fine matching.
