Abstract

Es wird ein Erregersystem fur eine Antenne mit einem parabelförmig gebogenen Reflektor (1) und einem dielektrischen Strahler (3) angegeben, der am Ende eines der Führung elektromagnetischer Wellen dienenden, zentral im Retlektor (1) angeordneten Hohlleiters angebracht ist und eine metallisierte, als Subreflektor ausgebildete Endfläche hat. Der Reflektor (1) ist zur Bildung einer Sektorantenne als rechteckiger Streifen ausgebildet, der in Richtung seiner großen Achse (A) parabelförmig gebogen ist. Die Endfläche des Strahlers (3) weist vier Teilflächen (8,9,10,11 ) auf, die paarweise gleich geformt und auf einander bezüglich der Mittelachse des Hohlleiters (2) gegenüberliegenden Seiten so angeordnet sind, daß die Flächen der beiden Paare etwa rechtwinklig zueinander verlaufen. Die beiden in Richtung der großen Achse (A) des Reflektors (1) weisenden Teilflächen (8,9) des Strahlers (3) sind groß im Verhältnis zu den beiden quer dazu angeordneten Teilflächen (10,11).An excitation system for an antenna with a parabolically curved reflector (1) and a dielectric radiator (3), which is at the end of one of the guides electromagnetic waveguide, arranged centrally in the retractor (1) waveguide is attached and has a metallized end surface designed as a sub-reflector. The reflector (1) is formed to form a sector antenna as a rectangular strip, which in the direction its major axis (A) is bent parabolically. The end face of the radiator (3) has four Partial surfaces (8,9,10,11), which have the same shape in pairs and on each other with respect to Center axis of the waveguide (2) opposite sides are arranged so that the surfaces of the two pairs are approximately at right angles to each other. The two towards the big one Axis (A) of the reflector (1) facing partial surfaces (8,9) of the radiator (3) are large in Relationship to the two transverse areas (10, 11).
