Abstract

The horn illuminator for reflector antennas with rectangular radia­ tion pattern is provided with a ring (4) of electrically conductive material coaxially placed before the horn mouth (3) a distance of λ/4 therefrom and in a plane parallel to that of said mouth (3). The elec­ trically conductive ring (4) is supported by a cap of polytetra­ fluoroethylene material acting as a protection therefor.
