Definitions

  • the invention is based on the type as indicated in the independent claim 1.
  • a waveguide switch which has a stator with four waveguide connection ports and a rotor in which waveguide paths are present which connect at least two waveguide connection ports to one another.
  • the switching of the signal paths takes place by rotation of the rotor (thereby also rotation of the waveguide paths in the rotor).
  • a high precision in the production of stator and rotor is required, especially for the combination of these parts only a very narrow gap between the stator and rotor is allowed, so that in the rule a very expensive precision storage is necessary.
  • the waveguide switch according to the invention consists of two partial shells, each having in particular symmetrically half of the waveguide structure and which are preferably produced in milling technology.
  • the corresponding 'switching path' is set by a simple, electrically conductive septum, for example by turning or pushing. No complex rotor / stator geometry is necessary. In addition, other switch configurations are possible.
  • a waveguide switch according to the invention can be constructed of parts whose manufacture does not require excessive precision, so that the manufacturing costs are substantially lower than in switches that correspond to the prior art. In addition, short switching times can be realized because the masses to be moved during switching are very small.
  • Figures 1a, b, c show three sectional views through a symmetrical switch arrangement, while the section CC is usually the half-shell division of the complete assembly, ie the stator half shell (without outer contour) with a movable element (here in the form of a rotor).
  • the arrangement has four waveguide connection ports 1, 2, 3, 4, wherein adjacent waveguide connection ports are each arranged at right angles to one another.
  • waveguide paths in the form of 90-degree E-plane elbows 12, 23, 34, 41 are introduced between adjacent waveguide connection gates, so that a corresponding branching results for each waveguide connection port.
  • a massive area 5 per Stator Halbschale is introduced in the complete branching region, ie within the circle 6, a gap 7 is provided between the stator half-shells, in which an electrically conductive septum 8 is introduced.
  • the septum 8 is shaped so that two opposite outer curvature contours 9, 10 almost the contours of the two emulate corresponding E-plane manifold. That is, through the septum 7, the E-plane bend for the desired waveguide paths 23, 41 are modeled. By contrast, the subregions of the other E-plane manifolds are covered.
  • the waveguide paths are divided by the septum 7 in the middle of its broad side in two 'sub-waveguide', so that in these areas, the cut-off wavelength is substantially smaller than the wavelength of the usable frequency band and thereby signal propagation is inhibited here.
  • a central, rotatable mounting of the septum 7 in the central solid area 5 allows a very easy switching of the waveguide paths, which takes place by a 90-degree rotation of the septum 7, see Figures 2a and b.
  • the septum 7 may be made with sliding contacts - however, it is advantageous to provide the conductive septum in isolation with respect to the waveguide region.
  • the septum 7 may have a frequency selective structure 13 (eg, bumps, ribs 16c, depressions, grooves, holes, slots, material discontinuities) which on the one hand compensates for the perturbations of the 'partial waveguide openings' and on the other hand increases the isolation between the 'blocked' waveguide paths.
  • a frequency selective structure 13 eg, bumps, ribs 16c, depressions, grooves, holes, slots, material discontinuities
  • septum 7 can be used simultaneously for marking the switch position by markings 14, 15, e.g. in conjunction with a light barrier.
  • FIG. 3 shows an arrangement in which the switching function is realized by pushing a septum 16.
  • the septum 16 has two separate areas 16a, 16b, one area of which has the configuration of one of the switch positions. So that these two areas can be displaced together in accordance with the arrows 17, a connecting part 18 is introduced between the areas 16a, 16b, which is located at a switch position in a continuous waveguide path (see FIG. 3a).
  • Either this connecting part 18 is designed so that it behaves electrically neutral (eg lambda / 4 transformation with transformation stages, formed by extensions 19 on the connecting part 18) or that caused by the connection part disturbance in the connection part itself or in the corresponding waveguide path (through suitable discontinuities 20) is compensated.
  • electrically neutral eg lambda / 4 transformation with transformation stages, formed by extensions 19 on the connecting part 18
  • connection part disturbance in the connection part itself or in the corresponding waveguide path through suitable discontinuities 20
  • the solution according to the invention can be applied to a multiplicity of different configurations, which, for example, also have more than four waveguide connection ports, as well as very individually designed switching options.
