Definitions

  • the invention relates to a waveguide polarization switch according to the preamble of claim 1.
  • a waveguide polarization switch for separating orthogonally linearly polarized electromagnetic waves has become known, for example, from DE-OS 26 51 935. It consists of an input-side waveguide section of square cross section, in which preferably H 10 and H01 waves are to be guided, which are linearly and orthogonally polarized with respect to one another with respect to their field strength vectors. In order to be able to separate the two polarizations, there are two opposing walls of the waveguide section recessed rectangular coupling window, each of which branches off a waveguide arm. Both branching arms are then combined again by interposing manifolds in a common broadband branch.
  • a somewhat more compact waveguide polarization switch is also known from DE-33 45 689 A1, in which the lateral waveguide arms branch off from the waveguide section at an acute angle and, after switching on an E-plane bend, to that through the longitudinal axis of the waveguide section given main direction are approximately parallel and converge in the broadband branch after switching on another, S-shaped E-level elbow.
  • Such high-precision parts are extremely expensive to manufacture.
  • a polarization switch milling from two full pieces that can be joined along their plane of symmetry For this purpose, a corresponding cast body is separated in the common central plane formed by the elbow and the feeding waveguide section and in both halves the feeding waveguide section guiding both polarizations and the two waveguide branches leading away from it for the continuation of the differently polarized electromagnetic waves including a short circuit piece and one on the opposite side to be inserted coupling window.
  • the present invention surprisingly creates the possibility of previously unknown Way to assemble a waveguide polarization switch from, for example, two cast parts.
  • the mold parts can be made, for example, from zinc, brass or, for example, also from an aluminum die casting.
  • the two components of the polarization switch are not separated in the plane formed jointly by the elbow and the feeding waveguide section, but rather are separated along a cutting plane running transversely thereto.
  • This cutting plane can now be arranged in the region of the coupling window lying transversely to the longitudinal extent of the coupling window in such a way that the cutting plane in principle leads through the elbow or angle in the H-elbow or angle and / or through the short-circuit piece arranged below the coupling window .
  • FIGS. 1 to 4 a polarizing switch 1, consisting of the components 1 'and 1 ⁇ , is shown.
  • a waveguide that can be connected here for example a waveguide that is square or round in cross section, e.g. one H10 and H01 or two H11 waves are transmitted, that is, two waves whose polarization planes are offset by 90 ° to one another in the direction of propagation.
  • a short-circuit step or bridge 9 which runs at right angles to the direction of propagation 7. Behind it, the further extending first waveguide branch 11 is reduced in height while the width of the waveguide remains the same, i.e. usually halved, so that here only the vertically polarized electromagnetic wave, i.e. H. a H10 wave is transmitted further.
  • the lower short-circuit stage 9 and an upper bridge 10 which reduces the cross-sectional height are shown in broken lines in FIG. 2.
  • a rectangular coupling opening or a coupling window 13 extends in the longitudinal direction centrally above the short-circuit stage 9.
  • the second waveguide branch 15 extends, which via a bend or an angle, in the exemplary embodiment shown an angle 17, to a polarization gate 21, which is above of the first polarization gate 19 connected to the first waveguide branch 11.
  • the angle 17 is an H-bend.
  • the first and second component 1 'and 1 ⁇ is separated by the cutting plane 23 which runs between the components and is shown in broken lines in the exemplary embodiment.
  • a projection 25 belonging to the elbow or angle 17 is shown, which protrudes beyond the actual cutting plane 23 and is nevertheless part of the first, i.e. in Figure 1 left component 1 'is the polarization switch.
  • the second component 1 ⁇ has a corresponding recess 27 into which the remaining projection 25, which forms part of the angle 17, engages when the components are joined together.
  • the first as well as the second component 1 'or 1 ⁇ can be formed in the die-casting process with walls that taper conically towards the exits. This makes it possible, in the die casting process, to move apart the molds and punches required for this purpose without mutual contact and friction in order to expose the components produced in this way. Warping already proves to be problematic here if individual walls would run directly in the direction of pull of the mold and stamp, which is why at least slightly widening wall sections are desired in the pull-out direction.
  • the exemplary embodiment shown in FIG. 4 is a waveguide polarization switch which is similar in principle and which is only shown in a vertical longitudinal sectional view.
  • the basic cutting plane 23 is arranged such that it does not cut the upper angle 17 and, in the case of a bend provided here, the bend itself.
  • a corresponding projection 25 ' is formed in the short circuit stage 9.
  • the projection 25 'belonging to the short-circuit stage 9' is designed to belong to the left-hand first component 1 'shown in FIG. 5, although in the assembled position it projects beyond the cutting plane 23 into the second component 1'.
  • the sectional plane 23 could be arranged exactly at the beginning of the short-circuit stage 9, so that in this case only the protrusion 25, as an outgoing part of the angle or Elbow 17 over the cutting plane 23 projecting to the first component 1 'would have to be formed.
  • FIG. 5 will now be used to explain in the embodiment according to FIG. 5 that an arrangement of the cutting plane in a central position relative to the embodiment according to FIGS. 1 to 4 or according to FIG 5 could be arranged so that both the upper and the lower projection 25 and 25 'are each associated with the opposite component 1' and 1 ⁇ and alternately protrude into the other component when joining over the actual theoretical cutting plane 23 .
  • the undercut 29 or 29 'behind the projections does not have to run back at right angles to the cutting plane 23, but can also run at an acute angle to the cutting plane 23, as shown in broken lines in Fig. 6a and 6b with the reference numerals 31 and 31 'is indicated.
  • tapered separating surfaces to the cutting plane 23 could also be offset such that each of the projection 25 or 25 'the further course of the separating plane between the two components 1' and 1 'did not return to the actual theoretical cutting plane 23, but parallel to the outside runs as shown in dashed lines in Figure 6a and Figure 6b with reference numerals 33 and 33 '.
  • the two components 1 'and 1 ⁇ are centered over projections 37 which are offset from the actual waveguides and which engage in corresponding blind holes 39 on the other component. Furthermore, further openings or bores are provided through which cylinder screws can be inserted and screwed down by unscrewing nuts.
  • both the opposite sections of the waveguide 3 and the subdivided waveguide branches 11 and 15 are formed as contact surface areas 41 which are slightly raised relative to the remaining side surface areas.
  • the individual waveguide line sections are provided with precisely fitting devices to achieve a snug fit and the two waveguide components can be produced with such accuracy and tolerance as die-cast or extruded parts that u.
  • U. reworking of the actual contact surface areas 41 is not necessary, this can nevertheless be carried out without problems at these points, since the actual contact surface areas 41 protrude somewhat. But despite any reworking that may be necessary here, the production costs are far lower than in the prior art, since the waveguide sections do not otherwise have to be worked out. Any necessary reworking is of little importance.
