Definitions

  • the present invention relates to a dielectric resonator according to the preamble of patent claim 1.
  • Such dielectric resonators are known from EP 0 316 813 A2.
  • Such a dielectric resonator has a cylindrical hollow housing which is made of metal, for example.
  • a gap-shaped space is formed in the dielectric resonator element, which comprises two cut-out parts with a U-shaped cross section and a diameter running in opposite directions.
  • a hollow part of the dielectric resonator element contains the two cutout parts running in opposite directions.
  • a cylindrical hollow tuning element made of a material with a high dielectric constant, such as ceramic, is inserted.
  • the outer shape of this tuning element is smaller than the inner shape of the hollow part of the dielectric resonator element. In this way, the tuning element can be moved in the axial direction of the hollow part of the dielectric resonator element by means of a bearing axis, as a result of which the dielectric resonator can be tuned.
  • a disadvantage of this known dielectric resonator is that the bearing axis for the tuning element has to be guided in a complex manner by means of bearings in the housing, so that the tuning element can be adjusted exactly in the hollow part of the resonator element by displacing the bearing axis.
  • the present invention is based on the object of specifying a structure of a dielectric resonator which is simpler with regard to the mounting and guidance of the tuning element.
  • a dielectric resonator according to the invention has a housing 1 in which a resonator element 2 having an opening 3 in the form of a blind hole is fastened. Furthermore, a dielectric tuning element 4, which can be inserted into the blind hole 3 in the resonator element 2, and an element 5 holding this tuning element 4 in the housing 1 in the form of a screw connected to the tuning element 4 and guided in the housing 1 are provided.
  • the resonator element 2 and the tuning element 4 are cylindrical, the diameter Dr of the resonator element 2 and the diameter Da of the blind hole 3 of the relationship 0.2 Dr ⁇ Da ⁇ 0.9 Dr to obey.
  • the depth Ta of the blind hole 3 and the height Hr of the resonator element 2 preferably obey the relationship Ta ⁇ 0.98 Mr.
  • the diameter Dab and the height Hab of the tuning element 4 and the diameter Da of the blind hole 3 preferably obey the relationships Dab ⁇ there and Have Ta 0.5 Ta.
  • an annular underlay 20 can be provided on the side facing away from the blind hole 3. This underlay 20 can be glued to the resonator element 2, for example.
  • the resonator element 2 can be designed as a step element with a step 30 provided on the side facing away from the blind hole 3.
  • the step 30 can in turn be provided with a recess 31.
  • the dielectric resonator according to the invention has the advantage of a large tuning range that is linear in the course with quality values that are almost constant over the entire tuning range.
