Definitions
- the invention is based on the genus as stated in independent claim 1.
- a waveguide switch which has a stator with four waveguide connection gates and a rotor in which waveguide paths are present which connect at least two waveguide connection gates to one another.
- the signal paths are switched by rotating the rotor (this also means rotating the waveguide paths in the rotor).
- Isolation requires a high precision in the manufacture of the stator and rotor, especially for the combination of these parts, only a very narrow gap between the stator and rotor is permissible, so that usually a very complex precision bearing is necessary.
- the waveguide switch according to the invention consists of two partial shells, each of which has, in particular, symmetrically half of the waveguide structure and which are preferably produced using milling technology.
- the corresponding 'switching path' is defined by a simple, electrically conductive septum e.g. adjusted by turning or pushing.
- a waveguide switch according to the invention can be constructed from parts, the manufacture of which does not require excessive precision, so that the production costs are significantly lower than for switches which correspond to the prior art. In addition, short switching times can be realized since the masses to be moved when switching are very small.
- FIG. 1 Schematic is shown in FIG. 1: the basic structure of an embodiment of the waveguide switch according to the invention with three sectional images,
- FIG. 2 an open three-dimensional representation (similar to an explosion drawing) of the waveguide switch according to FIG. 1 for two different switching states
- FIGS 3 and 4 further possible switch configurations that differ significantly from the previously known.
- Figures la, b, c show three sectional views through a symmetrical switch arrangement, the section C-C generally representing the half-shell division of the complete arrangement, i.e. the stator half-shell (without outer contour) with a movable element (here in the form of a rotor).
- the arrangement has four
- waveguide paths in the form of 90-degree E-plane elbows 12, 23, 34, 41 are introduced between adjacent waveguide connection gates, so that there is a corresponding branching for each waveguide connection gate.
- This arrangement leaves a solid area 5 per stator half-shell in the center of the arrangement.
- 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 opposing outer curvature contours 9, 10 almost the contours of the two corresponding E planes - Replica manifold. This means that the septum 7 simulates the E-plane bends for the desired waveguide paths 23, 41. In contrast, the sub-areas of the other E-level manifolds are covered. In these covered areas 12, 34, the waveguide paths are divided by the septum 7 in the middle of their broad side into two 'partial waveguides', so that in these areas the cut-off wavelength is significantly smaller than the wavelength of the useful frequency band and signal propagation is prevented here.
- a central, rotatable mounting of the septum 7 in the central solid area 5 enables the waveguide paths to be switched very easily, which is done by rotating the septum 7 by 90 degrees, see FIGS. 2a and b.
- the septum 7 can, for example, be designed with sliding contacts - however, it is advantageous to insulate the conductive septum with respect to the waveguide area. Furthermore, the septum 7 can have a frequency-selective structure 13 (for example elevations, ribs 16c, depressions, grooves, holes, slots, material discontinuities) which on the one hand compensates for the disturbances caused by the 'partial waveguide openings' and on the other hand increases the insulation between the 'blocked' waveguide paths.
- a frequency-selective structure 13 for example elevations, ribs 16c, depressions, grooves, holes, slots, material discontinuities
- septum 7 can also be used to mark the switch position by means of markings 14, 15, e.g. in connection with a light barrier.
- FIG. 3 shows, for example, an arrangement in which the switching function is implemented by pushing a septum 16.
- the septum 16 has two separate areas 16a, 16b, one area of which each has the configuration of one of the switch positions. So that these two areas can be moved together in accordance with the arrows 17, a connecting part 18 is introduced between the areas 16a, 16b, which is located in a continuous waveguide path (see FIG. 3a) when a switch is set.
- this connecting part 18 is to be designed so that it behaves in an electrically neutral manner (for example lambda / 4 transformation with transformation stages, formed by extensions 19 on the connecting part 18) or that the interference caused by the connecting part in the connecting part itself or in the corresponding waveguide path (through suitable discontinuities 20) is compensated.
- the compensation of the connecting part 18 can be carried out as follows: a) compensation by having approximately the length of a quarter wavelength; b) The connecting part 18 additionally has a transformer stage 19 to the adjoining waveguide sections, the dielectric being stepped or a dielectric with a different dielectric number being used; the length of the extensions 19 of the connecting part, which the
- Forming transformer stages corresponds to a quarter wavelength; c) the septum has (additional) discontinuities that are shifted with the septum, for example in FIG. 4a: inductive at the top, capacitive at the bottom
- discontinuity d) compensation by (additional) discontinuities / transformations (for example a change in cross-section of the waveguide in the area of the connecting part 18) which are located in the waveguide and are not displaced; this is possible if the discontinuities / transformations are in those parts of the waveguide that are only operated together with the connecting part 18 in the permeable switched operating state.
- the solution according to the invention can be applied to a large number of different configurations, which for example also have more than four waveguide connection gates, and to very individually designed switching options.
