Definitions

  • the present invention relates to a dual mode Ring resonator, which acts as a planar conduction ring on a Is arranged substrate to which an input and a Output line are coupled.
  • Dual-mode ring resonators in which a line ring two degenerate resonance modes are excited are off "EXPERIMENTAL INVESTIGATION OF DUAL MODE MICROSTRIP RING RESONATORS ", 20th European Microwave Conference 1990, page 901-906 and from IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES, Vol. 44, No. 5, May 1996, pages 723-729.
  • Such dual-mode ring resonators are used, for example, as Bandpass filter used, the one in its passband as low as possible pass attenuation and in its blocking area should have as high a blocking attenuation as possible.
  • the invention has for its object a dual mode Specify ring resonator of the type mentioned, the one the highest possible resonator quality and associated one has low attenuation in the pass band.
  • the conduit ring the shape of a Has squares with rounded corners and that the length of the Line ring is dimensioned so that the resonator at one of its odd harmonics is operated.
  • the bending radius of the cable ring is overall larger, and coupling the input and Output line puts less strain on the resonator, causing its radiation is significantly reduced. As a result of this takes its kindness too, and it affects the distance between that Ring resonator and the housing cover less strongly on the Resonance frequency off.
  • the larger dimension of the Line ring also has the advantage that it is less sensitive against manufacturing tolerances.
  • the input and output lines can Have tapered or widened pipes whose Length and width are dimensioned so that the cables coupled to the line ring with as little reflection as possible are.
  • the only figure shows a dual-mode ring resonator that operate on one of its odd harmonics should. It consists of a line ring 1, because of the Harmonic operation one double, four times, six times, ... so has a large length like a ring resonator, which at its Fundamental frequency is operated.
  • the line ring 1 has one square shape, with its four corners 2, 3, 4 and 5 are rounded. This square shape with the rounded corners 2, 3, 4 and 5 of the cable ring 1 can the known additional inhomogeneities for Coupling between the two modes on the line ring omitted. The absence of inhomogeneities reduces the Radiation from the cable ring and thus increases the quality of the Ring resonators.
  • Line sections 6 and 7 of the line ring 1 are one Input line 8 and an output line 9 coupled, which like the line ring 1 in stripline technology are executed. Coupling the input and Output line 8 and 9 to the line ring 1 is predominantly inductive. The degree of inductive coupling, which is determined by the distance between the input or Output line 8, 9 opposite the line sections 5 and 7 of the line ring 1 determines, has an influence on Position of the poles above and below the pass band in Area of the filter edges. Via the coupling of the input and Output lines 8 and 9 to line ring 1 can be So a desired location of the Set the poles.
  • the input line 8 and the output line 9 are each provided with a taper 10, 11.
  • the coupling of the input and Output line 8, 9 to the line ring 1 very Design with little reflection.
  • the adjustment line broadening may be required, as by the dashed lines indicated in the drawing.
  • the line ring 1 and the input line 8 and output line 9 coupled thereto are applied, for example, to an AL 2 O 3 ceramic substrate 12, the thickness of which is 0.381 mm. Both the line ring 1 and the input and output lines 8 and 9 have a conductor width of 0.34 mm. With a resonance frequency of 19 Ghz, the mean cable length of the cable ring 1 is approx. 10.6 mm, the cable taper 10, 11 are approx. 1.1 mm long and approx. 0.05 mm wide, and the coupling distance between the input and Output line 8, 9 and line ring 1 is approximately 0.13 mm.
