Definitions

  • the invention relates to an HF stripline resonator according to the preamble of claim 1.
  • HF stripline resonators are in stripline technology built-up resonant circuits for special applications are needed.
  • An important area of application is, for example the radio communication technology in which radio messages are transmitted in the radio wave range.
  • the the radio wave area covering sub-areas of radio communication technology are e.g. radio, television, cellular and satellite technology.
  • RF stripline resonators in Mobile radio systems is used in the following for the DECT cordless system shown.
  • DECT cordless system the simplest Case from a base station with at least one assigned Handset, high frequency signals are in Radio parts with a transmitter-receiver structure are required and processed.
  • Figure 1 shows e.g. the well-known (publication: ntz, vol. 46, Issue 10, 1993, pages 754 to 757 - "Architectures for one DECT transmitting and receiving part: a comparison ") principle Construction of a DECT radio part FKT according to the super heterodyne principle with double frequency conversion.
  • Mixers MIS are used that generate a useful signal (Transmit or receive signal) by mixing with an oscillator signal mix up or down (frequency of the useful signal up or down).
  • Oscillators OSZ1, OSZ2 are used for this purpose have trained resonators.
  • resonators HF stripline resonators are preferably used.
  • FIG. 2 shows the known structure of an HF stripline resonator 1, which is designed, for example, as a shortened quarter-wave resonator.
  • the quarter-wave resonator 1 is arranged, for example, on a printed circuit board 2 with a substrate thickness d S (target distance).
  • the quarter-wave resonator 1 has a strip line 10, which is connected at one end directly - by a through-contact DK - and at the opposite end via a capacitor 3 to a metallic conductor 11 serving as ground potential for the strip line 10 - in the present case a metallized conductor surface .
  • the strip conductor 10 and the metallic conductor 11 are arranged on mutually opposite surfaces of the printed circuit board 2.
  • the stripline 10 has a length l ST and a width b ST , through which the resonance frequency of the quarter-wave resonator 1 is determined together with the capacitance of the capacitor 3, the type of through-contact DK, the substrate thickness d S and the dielectric constant ⁇ r of the printed circuit board 2 .
  • the strip line resonator 1 is balanced by the capacitor 3 on the one hand with respect to the resonance frequency and on the other hand shortened with respect to the resonator length l ST .
  • the actual resonance frequency of the stripline resonator 1 is also determined by how exactly the stripline resonator 1 can be manufactured, ie how large the manufacturing tolerances are. Tolerances ( ⁇ d S ) in the substrate thickness d S or very generally in the distance between the strip conductor 10 and the metallic conductor 11 prove to be particularly problematic (difference between the desired distance d S and an actual distance d S ⁇ ⁇ d S ) .
  • DE-34 24 824 A1 and GB-2 222 312 A are HF stripline resonators with curved ones arranged on a support Stripline known in which the curved Stripline shape serves the dimensions of the RF stripline resonator to reduce.
  • the object underlying the invention is to specify an RF stripline resonator in which by production-related, the distance "strip line - metallic Tolerances influencing the structure of the HF stripline resonator changes occurring in the Resonance frequency of the resonator can be compensated.
  • This task is based on that in the preamble of Claim 1 specified HF stripline resonator by the in the characterizing part of claim 1 specified features solved.
  • FIG. 3 An exemplary embodiment of the invention is illustrated in FIG. 3 explained.
  • FIG. 3 shows, starting from the HF stripline resonator 1 according to FIG. 2, a modified HF stripline resonator 1 a, in which the strip conductor 10 has a curved course.
  • the curvature is chosen so that when there are fluctuations in distance (target distance d S and actual distance d S ⁇ ⁇ d S ) between the strip conductor 10 and the metallic conductor 11, capacitively induced resonance frequency shifts in the HF stripline resonator la caused by approximately the same inverse inductance Resonance frequency shifts can be compensated.
