Abstract. The article presents the method of synthesis of the current’s amplitude-phase distribution on the dish antenna’s reflection surface, that preserves the given constant pattern characteristics over a wide frequency band. The fundamental relations are presented and properties of the amplitude-phase distribution, which supports stability characteristics of the radiation pattern over the three-octave frequency band, are investigated on the example of a parabolic cylinder.

Keywords: reflector antenna, parabolic cylinder, reflector, amplitude phase distribution, surface currents, radiation pattern.
