Abstract :
Some theoretical deductions and results in agreement with some design inferences and experimental measurements, included NEC2 code simulations, are proposed as a further step in Vivaldi antenna analysis. The exponential taper scaling invariance and the decreasing current distribution are proved and a practical feeding system is developed in order to obtain a quite complete study about the main Vivaldi antenna features and properties
