Some results of the numerical investigation of a wideband ridge-type horn radiator are presented. The main attention is paid to the matching between the radiator and a 50-oh coaxial feeding line and to simulation of the amplitude-phase patterns including the phase center location. It is shown that radiators of this type could be used not only as an ultra-wideband antenna, but as a feed for the aperture antennas as well.
