Definitions

  • the present invention relates to a dielectric resonator which has a dielectric body arranged in a housing.
  • Such a dielectric resonator is e.g. known from EP 316 813 A1.
  • No means are provided for the dielectric cylinder, which is mounted on a dielectric ring in the housing, in order to avoid heat concentrations by a suitable heat distribution or to dissipate heat to the outside.
  • heat-dissipating means consist of two metal disks, between which the resonator is clamped.
  • a ceramic core that can be inserted centrally into the interior of the dielectric resonator is used to tune the resonance frequency.
  • No. 2,890,422 discloses a dielectric resonator into which one or more rods with a higher permeability are introduced centrally or eccentrically in order to influence the resonance frequency.
  • a dielectric resonator known from US Pat. No. 5,097,238 is provided with a central bore in order to enlarge the contact area with the atmosphere and thus to effect better heat dissipation.
  • the invention has for its object to provide a dielectric resonator of the type mentioned, which is provided with means for high heat concentrations in the to avoid dielectric body or to allow good heat dissipation to the outside, these means should impair the quality of the resonator as little as possible.
  • one or more metal bodies are integrated in the dielectric body according to the invention, the heat generated therein is distributed more evenly over the volume of the body. High heat concentrations in some areas, which deteriorate the resonator quality and can also lead to the destruction of the dielectric body, are thus reduced.
  • holders for the dielectric body can be connected in a simple manner. These holders can advantageously also be used to dissipate the heat from the dielectric body to the outside of the housing.
  • Figures 1 to 5 show a longitudinal section through a dielectric body arranged in the housing 1, e.g. in the form of a cylinder 2.
  • the cross-sectional shapes of the housing 1 and the cylinder 2 held therein can be chosen as desired, depending on the application; you can e.g. be rectangular, triangular, elliptical, etc.
  • At least one metal body in the form of a rod is integrated in the dielectric cylinder 2.
  • the drawing shows exemplary embodiments with only one integrated metal rod.
  • each metal rod must be placed in such a way that it is oriented as orthogonally as possible to the electrical and magnetic field lines of the resonator.
  • TEO1 ⁇ resonator wave type e.g. this condition is fulfilled for metal rods which are oriented parallel to the cylinder axis in the maximum of the electric field or radially to the cylinder axis.
  • rods made of metal can be used without any significant loss in resonator quality, which, because of their good thermal conductivity, are able to distribute amounts of heat in the dielectric cylinder 2 in such a way that there are no partially high heat concentrations.
  • the metal rod 3 integrated in the dielectric cylinder 2 is oriented parallel to the cylinder axis and extends over the entire cylinder height.
  • the dielectric cylinder 2 is to be arranged as centrally as possible in the resonator housing 1.
  • it is fixed on a dielectric block 4 in the housing 1.
  • a very good heat dissipation can be achieved in that the holder of the dielectric cylinder 2 consists of one or more metal bars 5, 6, which are connected to the integrated metal bar 6. 3, each of the two ends of the metal rod 3 integrated in the dielectric cylinder 2 is connected to a metal rod 5, 6.
  • the connection between the metal rods 3, 5, 6 can be made, for example, by screwing, in that one rod has a threaded hole and the other rod has a matching threaded pin.
  • the rods 5, 6 are guided through the interior of the housing 1 in such a way that the rods 5, 6 are aligned as orthogonally as possible to the electrical and magnetic field lines.
  • heat distribution or dissipation may be sufficient. also a metal rod 7, which does not extend over the entire height of the dielectric cylinder 2 and is also only connected to a holding rod 8.
  • FIG. 4 The embodiment shown in FIG. 4 is similar to that of FIG. 3 in that the dielectric cylinder 2 has a metal rod 9 which completely traverses it, the two ends of which are connected to holding rods 10, 11 which are made of metal for effective heat dissipation.
  • the rods 9, 10, 11 are oriented orthogonally to the longitudinal axis of the cylinder.
  • Fig. 5 illustrates that instead of a continuous integrated metal rod, several shorter metal rods 12, 13 can be used, each of which is connected to a holding rod 14, 15.
  • the metal bodies integrated in the dielectric cylinder can e.g. be designed as a threaded bushing, which allow easy attachment of external holding rods.
  • All of the metal rods of the previously described exemplary embodiments can be hollow on the inside, so that a cooling liquid or a cooling gas can thereby be conducted to improve the heat dissipation from the dielectric cylinder
  • a metallized bore can be provided at a corresponding point in the dielectric cylinder. This hole can e.g. be filled with a good heat-conducting dielectric.
