Description

Antennensystem mit einem Strahlungsdiagramm, dessen Maximum um die Systemachse rotiert Es sind Verfahren bekannt zur Steuerung von Flugkörpern längs einer vorgegebenen Leitachse, welche dabei die Achse eines Kegels darstellt, auf dessen Mantel das Maximum des Strahlungsdiagramms einer vorzugsweise im Ultrakurzwellenbereich liegenden elektromagnetischen Schwingung rotiert (z. B. schweizerische Patentschrift 261 423).Antenna system with a radiation pattern, the maximum of which is around the System axis rotates Methods are known for controlling missiles longitudinally a predetermined master axis, which represents the axis of a cone whose jacket is the maximum of the radiation diagram, preferably in the ultra-short wave range rotating electromagnetic oscillation (e.g. Swiss patent specification 261 423).

Es sind Antennensysteme bekannt, welche zur Durchführung derartiger Verfahren geeignet sind (z. B. schweizerische Patentschrift 262 006). Danach wird das die Schwingung ausstrahlende Strahlerelement bei kreisförmiger Bahn um die Systemachse bewegt, wobei die Richtung des Strahlerelementes im Raum und damit die Polarisationsebene der Schwingung wenigstens angenähert unverändert bleiben. Das Strahlerelement bildet sich dabei stets nahe dem Brennpunkt eines parabolförmigen Reflektors, dessen Achse die Systemachse bildet.Antenna systems are known which are used to carry out such Processes are suitable (e.g. Swiss patent specification 262 006). After that, will the radiator element radiating the vibration with a circular path around the system axis moves, the direction of the radiator element in space and thus the plane of polarization the oscillation remain at least approximately unchanged. The radiator element forms always close to the focal point of a parabolic reflector, its axis forms the system axis.

Die Erfindung betrifft ein Antennensystem, welches ebenfalls zur Durchführung dieses Verfahrens geeignet ist. Es dient der Erzeugung eines um die Systemachse rotierenden Strahlungsdiagramms der genannten Art mit einer Rotationsfrequenz von beispielsweise 100 Hz. Das erfindungsgemäßie System weist in hochfrequenztechnischer Hinsicht den Vorteil auf, daß sich vor dem parabolförmigen Reflektor, d. h. auf der Seite seines Breenpunktes, nur das Strahlerelement und der zu seiner Halterung und Bewegung dienende Träger befinden; übrigen Teile sind hinter dem Reflektor angeordnet und können daher die Gestalt des Strahlungsdiagramms nicht beeinflussen. In mechanischer Hinsicht bietet das System den Vorteil, daß der Massenausgleich direkt an dem die Unwucht verursachenden Teil stattfindet. Dadurch sind mit Spiel behaftete Lagerstellen und das die einzelnen Teile tragende Gehäuse von Ausgleichskräften und -momenten entlastet, und der Massenausgleich ist trotz geringerer Anforderungen an die Starrheit des Gehäuses mit größerer Präzision durchführbar. The invention relates to an antenna system which is also used for Carrying out this procedure is appropriate. It is used to generate a System axis rotating radiation diagram of the type mentioned with a rotation frequency of, for example, 100 Hz. The system according to the invention has high-frequency technology Regarding the advantage that in front of the parabolic reflector, d. H. on the side of its Breenpunkt, only the radiator element and the one to its holder and movement serving carriers are located; remaining parts are behind the reflector and can therefore not change the shape of the radiation pattern influence. From a mechanical point of view, the system has the advantage that the mass balance takes place directly on the part causing the imbalance. This gives you a game afflicted bearing points and the housing carrying the individual parts of compensating forces and moments relieved, and the mass balance is despite lower requirements feasible to the rigidity of the housing with greater precision.

Das erfindungsgemäße Antennensystem ist gekennzeichnet durch einen rofirförmigen Träger, an dessen einem, nahe dem Brennpunkt des Reflektors befindlichen Ende das Strahlerelement angeordnet ist. Ein Punkt des Trägers wird durch ein Kardangelenk auf der Systemachse festgehalten. Ein anderer Punkt des Trägers wird durch eine motorisch angetriebene, sich um die Achse drehende Kurbel kreisförrmg um die Achse herumgeführt. The antenna system according to the invention is characterized by a Rofir-shaped support, on one of which is located near the focal point of the reflector The end of the radiator element is arranged. One point of the girder is through a universal joint held on the system axis. Another point of the wearer is through a motor-driven crank rotating around the axis circularly around the axis shown around.

Auf der Kurbel befindet sich an feiner bezüglich der Achse dem Träger gegenüberliegenden Stelle eine erste Ausgleichsmasse; eine zweite Ausgleichsmasse ist auf dem Träger selbst zwischen dem Kardangelenk und der Kurbel angeordnet. Motor, Kurbel und die beiden Ausgleichsmassen befinden sich hinter dem Reflektor.On the crank there is the carrier on finer with respect to the axis opposite point a first balancing mass; a second leveling compound is arranged on the carrier itself between the universal joint and the crank. Engine, The crank and the two balancing weights are located behind the reflector.

Ein erstes Ausführungsbeispiel eines erfindungsgemäßen Antennensystems sei an Hand der Fig. I beschrieben. Es bedeutet I den parabolischen Reflektor, 2 das Strahlerelement, 3 den rohrförmigen Träger, 4 das Kardangelenk, 5 die Kurbel, 6 die erste Ausgleichsmasse, 7 die zweite Ausgleichsmasse, 8 den Motor. Das Kardangelenk befindet sich im Scheitel des Reflektors, welcher somit nur eine kleine Öffnung aufweisen muß. Die Kurbel treibt den Träger an seinem vom Strahlerelement abgewandten Ende an. A first embodiment of an antenna system according to the invention is described with reference to FIG. It means I the parabolic reflector, 2 the radiator element, 3 the tubular support, 4 the universal joint, 5 the crank, 6 the first balancing mass, 7 the second balancing mass, 8 the motor. The universal joint is located in the apex of the reflector, which is therefore only a small opening must have. The crank drives the carrier on its remote from the radiator element End at.

Die Zuführung der Schwingungsleistung an das Strahlerelement kann durch ein flexibles Kabel erfolgen, welches am Ort des Kardangelenkes in den rohrförmigen Träger eintritt. The supply of the vibration power to the radiator element can done by a flexible cable, which at the location of the universal joint in the tubular Porter enters.

Ein zweites Ausführungsbeispiel eines erfindungsgemäßen Antennensystems sei an Hand der Fig. 2 beschrieben. Die einzelnen Teile sind gleich bezeichnet wie oben. Das Kardangelenk befindet sich hier an dem vom Strahlerelement abgewandten Ende des Trägers. Dadurch wird die Zuführung der Schwingungsleistung an das Strahlerelement besonders leinfach. Sie kann ebienfalls durch ein flexibles Kabel erfolgen, welches im rohrförmigen Träger verläuft, diesen beim Kardangelenk verläßt und sich dann längs der Systemachse erstreckt. A second embodiment of an antenna system according to the invention is described with reference to FIG. The individual parts are labeled in the same way as above. The cardan joint is located here on the one facing away from the radiator element End of the beam. This ensures that the vibration power is fed to the radiator element particularly easy. It can also be done by a flexible cable, which runs in the tubular support, leaves this at the universal joint and then extends along the system axis.

An Stelle eines Kabels läßt sich jedoch in einem Antennensystem gemäß Fig. 2 mit Vorteil eine Rotationskupplung zur kapazitiven Übertragung der Schwingungsleistung anwenden. Die Kurbel befindet sich nahe dem Scheitel des Reflektors. Sie wird über das Zahnradpaar 9, 10 durch den Motor angetrieben.Instead of a cable, however, in an antenna system according to FIG. 2 advantageously shows a rotary coupling for the capacitive transmission of the vibration power use. The crank is near the top of the reflector. She is going over the gear pair 9, 10 driven by the motor.

Dieses System besitzt den Vorteil, daß bei gegebenen Abständen zwischen Reflektorscheitel und Strahlerelement einerseits, Achse und StrahXerelement anderseits die Richtungsänderungen des Strahl,erelementes bei der Rotation wegen des größeren Abstandes zwischen Strahlerelement und Kardangelenk geringer sind als beim System gemäß Fig. I. This system has the advantage that given the distances between Reflector vertex and radiator element on the one hand, axis and radiator element on the other the changes in direction of the beam element during rotation because of the larger Distance between the radiator element and the universal joint are smaller than with the system according to Fig. I.
