Description

Die Erfindung befaßt sich mit einer Kompensations-Anordnung für zwei miteinander axial fluchtende und einander stoßende Rechteck-Hohlleiter gleichen Querschnitts, wobei deren Querschnitte relativ gegeneinander um einen Winkel verdreht sind und bei der zur breitbandigen Kompensation im Bereich der Hohlleiter-Stoßstelle ein geeignetes Blindwiderstandselement angebracht ist.The invention is concerned with a compensation arrangement for two axially aligned and rectangular waveguides abutting one another with the same cross-section, their cross-sections being relative to one another are rotated by an angle and in the case of broadband compensation in the area of the waveguide junction a suitable reactance element is attached.
Eine derartige Anordnung wurde bereits in der DE-OS 27 48 956 vorgeschlagen für den Anschluß einer Antenne an ein Richtfunksystem, um damit im Bedarfsfall die Richtung der Polarisation einer übertragenen Welle einsteilen zu können. Beispielsweise kann man die Hohlleiter so gegeneinander verdrehen, daß die übertragene Welle entweder horizontal oder vertikal polarisiert wird.Such an arrangement has already been proposed in DE-OS 27 48 956 for the connection of an antenna to a radio relay system in order to determine the direction of the polarization of a transmitted wave if necessary to be able to arrange. For example, you can twist the waveguide against each other so that the transmitted Wave is polarized either horizontally or vertically.
Vorliegende Erfindung hat sich bei einer derartigen Anordnung die Aufgabe gestellt, die Kompensation der Hohlleiter-Stoßstelle in möglichst einfacher Weise zu lösen.The present invention has set itself the task of compensating for the To solve the waveguide joint in the simplest possible way.
Erfindungsgemäß wird dies dadurch gelöst, daß das Blirdwiderstandselement durch eine zwischen den Flanschen der Hohlleiter eingefügte metallische Scheibe realisiert ist, die eine dem resultierenden Öffnungsquerschnitt der Hohlleiter entsprechende Aussparung aufweist und mit zwei in diesen Querschnitt hineinragenden, kapazitive Belastungen darstellenden Vorsprüngen versehen ist, die symmetrisch zur Längs- und Quer-Ausdehnung der Aussparung ausgebildet und einander gegenüberliegend angeordnet sind.According to the invention, this is achieved in that the blird resistance element by a between the flanges the waveguide inserted metallic disc is realized, which is one of the resulting opening cross-section the waveguide has a corresponding recess and with two protruding into this cross-section, Capacitive loads representing projections is provided, which are symmetrical to the longitudinal and transverse expansion the recess are formed and arranged opposite one another.
Anhand der Figuren soll im folgenden die Erfindung näher erläutert werden.The invention is to be explained in more detail below with reference to the figures.
In der F i g. 1 ist durch die stark umrandete Linie die öffnung dargestellt, welche in dem Kompensationsblech 3 angebracht wird. Mit 1 und 2 sind die beiden Hohlleiter bezeichnet, die um ihre Hauptachse gegeneinander um einen Winkel <x verdreht sind. Man erkennt bei 6 und 7, daß die Aussparung im Kompensationsblech 3 dort zwei kapazitive Belastungen aufweist, wo das Blech in den resultierenden Öffnungsquerschnitt der beiden Hohlleiter hineinragt. Diese Belastung verläuft symmetrisch zur Halbierenden des kleineren Winkels zwischen den beiden kleinen Achsen der Hohlleiter.In FIG. 1, the strongly bordered line shows the opening which is made in the compensation plate 3. With 1 and 2, the two waveguides are referred to, which are rotated about their main axis against each other by an angle <x. It can be seen at 6 and 7 that the recess in the compensation plate 3 has two capacitive loads where the plate protrudes into the resulting opening cross-section of the two waveguides. This load runs symmetrically to the bisector of the smaller angle between the two small axes of the waveguide.
In der F i g. 2 ist die Draufsicht dargestellt auf zwei gegeneinander verdrehte Hohlleiter 1 und 2, zwischen deren Endflanschen 4 und 5 das Kompensationsblech 3 angeordnet istIn FIG. Figure 2 shows the top view of two Waveguides 1 and 2 twisted against each other, with the compensation plate 3 between their end flanges 4 and 5 is arranged
Für Anwendungsfälle, bei denen eine kontinuierliche Verdrehung über einen größeren Winkelbereich bei gleichbleibender Fehlanpassung erforderlich ist, wird die Anordnung zweckmäßigerweise so ausgebildet daß das Kompensationsblech durch eine Zwangsführung jeweils auf der Winkelhalbierenden gehalten wird. Dies erreicht man dadurch, daß man in einem Flansch und in dem Kompensationsblech je eine Aussparung anbringt und durch einen in diese Nuten eingreifenden Führungsstift die Zwangsführung bewirkt. For applications in which there is a continuous rotation over a larger angular range constant mismatch is required, the arrangement is expediently designed so that the compensation plate is held on the bisector by a positive guide. this is achieved by making a recess each in a flange and in the compensation plate and the positive guidance is effected by a guide pin engaging in these grooves.
Die Dicke des Kompensationsbleches und die Größe der in den resultierenden Öffnungsquerschnitt hineinragenden Kapazitätsbelastungen 6 und 7 werden bei dem jeweils gegebenen Hohlleiterquerschnitt experimentell bestimmt.The thickness of the compensation plate and the size of the one that protrudes into the resulting opening cross-section Capacitance loads 6 and 7 are experimental for the given waveguide cross-section certainly.
Bei Verwendung von zwei genormten Rechteckhohlleitern R/40 beispielsweise wurde die kapazitive Belastung so gewählt, daß der in den resultierenden Hohlleiterquerschnitt hineinragende Teil des Kompensationsblech« ca. 1/8 (b Hohlleiterschmalseite) lang war und seitlich entsprechend dem Verdrehungswinkel geradlinig begrenzt wurde. Die Blechdicke betrug dabei 0,3 mm.When using two standardized R / 40 rectangular waveguides, for example, the capacitive load chosen so that the part of the compensation plate protruding into the resulting waveguide cross-section « was approx. 1/8 (b waveguide narrow side) long and straight on the side according to the twist angle was limited. The sheet thickness was 0.3 mm.
Durch die erfindungsgemäß aufgebaute Kompensations-Anordnung konnte eine breitbandige Kompensation erzielt werden, da die Störung am Ort ihrer Entstehung kompensiert wird. Die Anordnung ermöglicht eine ausreichende Kompensation für verschiedene, gegebenenfalls kontinuierlich einstellbare Verdrehungswinkel. Außerdem ist es leicht möglich, das zwischen den Flanschen angeordnete Kompensationsblech zu entfernen, wenn ein Verdrehungswinkel von 0° erforderlich ist.Due to the compensation arrangement constructed according to the invention a broadband compensation could be achieved, since the disturbance at the place of its origin is compensated. The arrangement enables sufficient compensation for various, if necessary continuously adjustable angle of rotation. It is also easily possible to do this between the flanges to remove the compensation plate if a rotation angle of 0 ° is required.
