Abstract
The results of design and experimental study are presented for ultrawideband Vivaldi radiators, operating in (6-18) GHz band and having the geometry providing high level of matching, stability of far field patterns and convenience for practical realization of the excitation circuit. To realize signal reception with both clockwise and counterclockwise circular polarizations, the bridge device is developed, based on the coupled lines.
