Definitions

  • the present invention relates to a reflection resonator, consisting of a dielectric resonator, which is dimensioned such that whispering gallery modes can be excited therein, a signal line being coupled to the dielectric resonator, which serves to supply waves to the dielectric resonator and to reflect reflected waves to return the resonance frequency of the dielectric resonator.
  • a dielectric TE / TM mode resonator is known, the signal line of which is branched into two waveguides coupled to the resonator. This waveguide branching is intended to achieve a stronger coupling of TE or TM modes to the dielectric resonator.
  • dielectric Whispering Gallery mode resonators are an advantage over conventional dielectric TE / TM mode resonators.
  • the dielectric Whispering Gallery Mode Resonator has a much higher quality and can have considerably larger dimensions than the dielectric TE / TM Mode Resonator. Because with the latter, the dimensions depend on the extent of the TE or TM mode existing in it, which is extremely small in the millimeter wave range. Dielectric However, resonators with very small dimensions are very difficult to manufacture with the required tolerances.
  • a signal line designed as a microstrip line is coupled to the dielectric whispering gallery mode resonator.
  • the coupling of an idling microstrip line to the dielectric resonator used here leads to a splitting of the resonance frequencies of the degenerate whispering gallery modes, which leads to a generally undesirable blurring of the frequency dependence of the reflection factor of the reflection resonator.
  • the invention is based on the object of specifying a reflection resonator of the type mentioned at the outset, the reflection factor of which has a defined frequency characteristic which has been freed of split resonance frequencies.
  • the reflection resonator shown in the drawing is realized with a dielectric resonator DR, which is dimensioned such that whispering gallery mode can be excited in it.
  • a dielectric resonator DR which is dimensioned such that whispering gallery mode can be excited in it.
  • the reflection resonator has a signal line L at the input, which is branched into two waveguides L1 and L2 connected in parallel. Each of these two waveguides L1 and L2 is coupled to the dielectric resonator DR.
  • the two waveguides L1 and L2 are, for example, microstrip lines; but it can also be lines made in other technology, for example dielectric image lines, waveguides, etc.
  • waves are fed to the dielectric resonator DR via the signal line L and the waveguides L1 and L2 branching therefrom, and on the other hand those waves are reflected which are reflected by the dielectric resonator DR because they have the resonance frequencies of the dielectric resonator DR.
  • the resonance frequencies of the dielectric resonators DR depend on its dimensioning.
  • the magnitude of the reflection factor of the reflection resonator is greater the more the waveguides L1 and L2 are coupled to the dielectric resonator DR.
  • the coupling is determined by the distance of the resonator from the waveguides L1 and L2 and the effective coupling length.
  • the phase of the reflection factor depends on the distance of the dielectric resonator DR from the branch point of the two waveguides L1 and L2.
  • the two waveguides L1 and L2 can have different lengths and can be coupled at any point on the circumference of the dielectric resonator DR.
  • each of the two waveguides L1 and L2 is terminated with its characteristic impedance.
  • waves whose frequencies do not match the resonance frequencies of the dielectric resonator DR are largely damped.
  • the reflection factor of the reflection resonator should therefore deviate as little as possible from zero outside the resonance frequency. This goal is achieved in that the interconnection of the waveguides L1 and L2 results in the characteristic impedance of the signal line L.
