Abstract
Simulated and measured results of an ultrawideband Vivaldi radiators are presented. An enhanced feeding system of this antenna allows us to increase the operating frequency band. A good matching (VSWR better than 2) in the prototype and sufficiently low insertion losses over a three-octave frequency interval were reached.
