Abstract (en)

The antenna includes a main reflector, in front of which, in the direction of incident radiation, a sub-reflector with a reflecting surface is rotatably arranged. The sub-reflector (2) comprises a cylindrical axis (23) that lies in the direction of a main axis (22) of the main reflector (1), the sub-reflector being rotatably mounted on the cylindrical axis so that it can rotate at high speeds of 1500 to 3500 rpm. The sub-reflector may be mounted in an vibration-free manner, and free from unbalance. An Independent claim is included for a method of manufacturing a reflector for a reflecting antenna.

Abstract (de)

Reflektorantenne mit einem Hauptreflektor, vor dem in Richtung einfallender Strahlen ein mit einer reflektierenden Fläche versehener Subreflektor drehbar angeordnet ist. Der Subreflektor weist eine in Richtung einer Hauptachse des Hauptreflektors verlaufende Zylinderachse auf, auf der der Subreflektor mit einer hohen Drehzahl von etwa 1500 bis etwa 3500 U/min. drehbar gelagert ist. In dem Verfahren zum Herstellen des Reflektors werden zwei im Wesentlichen zylindrische Teilstücke aus einer nicht reflektierenden Masse hergestellt. <IMAGE>
