Abstract

A method for producing a rectangular waveguide curve comprises a rectangular waveguide (RH) whose four walls have a constant wall thickness being bent over a support (A) which has the form of a section of a circular arc, the transition zones (Ü1, Ü2) which run in a straight line and are produced during the bend in the curvature zone (K), being adjacent thereto on both sides, not being influenced by the deformation of the waveguide walls which is intrinsically produced. <IMAGE>

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen eines Recht­ eckhohlleiter-Krümmers durch Biegen eines Rechteckhohlleiters in seiner E- oder H-Ebene.The present invention relates to a method for establishing a right corner waveguide bend by bending a rectangular waveguide in its E- or H level.

Aus der DE-OS 24 30 847 ist beispielsweise ein Rundhohlleiter-Krümmer mit einem sehr großen Krümmungsradius (ca. 70 m) bekannt, der, um die darin auftretenden Signalverzerrungen möglichst gering zu halten, aus mehreren gekrümmten Hohlleiterabschnitten und dazwischenliegenden geraden, als Wel­ lentypfilter dienenden Hohlleiterabschnitten zusammengesetzt ist. Die Herstel­ lung eines solchen Hohlleiter-Krümmers mit abwechselnd geraden und gebo­ genen Hohlleiterabschnitten ist aufwendig.From DE-OS 24 30 847, for example, a circular waveguide bend is included a very large radius of curvature (approx. 70 m) is known to be the one in it keep signal distortions as low as possible, from several curved waveguide sections and straight lines in between, as Wel ltype filter serving waveguide sections is composed. The manufacturer development of such a waveguide bend with alternating straight and curved gene waveguide sections is complex.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Herstellen eines Rechteckhohlleiter-Krümmers anzugeben, das mit geringem Aufwand durch­ führbar ist und einen Rechteckhohlleiter-Krümmer hervorbringt, der die Si­ gnalübertragungsqualität möglichst wenig beeinträchtigt.The invention has for its object a method for producing a Rectangular waveguide elbow specify that with little effort is feasible and produces a rectangular waveguide manifold that the Si Signal transmission quality affected as little as possible.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. This object is solved by the features of claim 1.  

Eine zweckmäßige Weiterbildung der Erfindung geht aus dem Unteranspruch hervor.An expedient development of the invention results from the subclaim forth.

An Hand eines in der Zeichnung dargestellten Ausführungsbeispiels wird nun die Erfindung näher erläutert.Based on an embodiment shown in the drawing the invention explained in more detail.

Die Figur in der Zeichnung zeigt einen Rechteckhohlleiter RH, der über eine als Halbkreisbogen geformte Auflage A um einen Winkel α (hier z.B. 90°) gebogen ist. Wird der Rechteckhohlleiter RH in seiner E-Ebene gebogen, so wird eine Auflage A verwendet, deren Kreisbogenradius R ca. 3 λ beträgt, und wird er in seiner H-Ebene gebogen, so erfolgt die Biegung über eine Auflage A mit einem Kreisbogenradius R von ca. 4 g, wobei λ die Frei­ raumwellenlänge ist.The figure in the drawing shows a rectangular waveguide RH which is bent by an angle α (here, for example, 90 °) over a support A shaped as a semicircular arch. If the rectangular waveguide RH is bent in its E-plane, then a support A is used, the circular arc radius R of which is approx. 3 λ , and if it is bent in its H-plane, the bending takes place via a support A with a circular arc radius R of approx. 4 g , where λ is the free space wavelength.

Beim Biegen verformen sich, wie durch die Strichlierung in der Zeichnung angedeutet, die Wände des Rechteckhohlleiters RH, dessen vier Wände eine konstante Wandungsstärke aufweist. Der Biegevorgang hinterläßt in der Krümmungszone K und in den sich zu beiden Seiten daran anschließenden, gerade verlaufenden Übertragungszonen Ü 1 und Ü 2 eine Querschnittsverfor­ mung des Rechteckhohlleiters RH. Diese sich bei den gewählten Biegeradien ganz von selbst einstellende Verformung wird absichtlich nicht beeinflußt. Denn die Querschnittsform des Rechteckhohlleiters in der Krümmungszone K wirkt zusammen mit den Verformungen der etwa 3/4 λ langen, sich allmäh­ lich an den Normalquerschnitt des Rechteckhohlleiters anpassenden Übergangs­ zonen Ü 1 und Ü 2 so, daß insgesamt der Rechteckhohlleiter-Krümmer eine weitgehend reflexionsfreie Signalübertragungsstrecke darstellt.When bending, the walls of the rectangular waveguide RH, the four walls of which have a constant wall thickness, deform, as indicated by the dashed lines in the drawing. The bending process leaves a cross-sectional deformation of the rectangular waveguide RH in the curvature zone K and in the straight transmission zones U 1 and U 2 adjoining it on both sides. This deformation, which occurs completely automatically in the selected bending radii, is intentionally not influenced. Because the cross-sectional shape of the rectangular waveguide in the curvature zone K acts together with the deformations of the approximately 3/4 λ long, gradually adapting to the normal cross section of the rectangular waveguide transition zones Ü 1 and Ü 2 so that overall the rectangular waveguide manifold has a largely reflection-free signal transmission path represents.
