Abstract

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.

Figure 00000001
Reflector antenna with a main reflector, in front of which a sub-reflector provided with a reflecting surface is rotatably arranged in the direction of incident rays. The subreflector has a cylinder axis running in the direction of a main axis of the main reflector, on which the subreflector runs at a high speed of about 1500 to about 3500 rpm. is rotatably mounted. In the method for producing the reflector, two essentially cylindrical sections are produced from a non-reflecting mass.
