Definitions
- the desired resonance frequency at which the ring resonator Filtering a narrow frequency range should vibrate can be set very precisely.
- Such printed Ring resonators usually have material fluctuations and Manufacturing tolerances, especially at higher ones Frequencies, because of the small dimensions of the Ring resonators affect manufacturing tolerances more. Therefore, a printed ring resonator points to its Manufacturing usually not the exact one you want Resonance frequency. So there has to be a comparison afterwards the resonance frequency take place, although the May only slightly deteriorate the quality of the resonator, because for the electrical properties of the oscillator or of the filter is the highest possible quality of the resonator important.
- the above task is either with the characteristics of Claim 1 solved in that with a laser to one or several points of the stripline ring is removed until a desired one Sets resonance frequency, or with the features according to Claim 2 characterized in that at one or more points stripline coupled to the stripline ring a laser wire material is removed until a desired resonance frequency is set.
- pipe material is used in places the stripline ring where current maxima occur, removed when the resonance frequency is lowered or in places where current minima occur in order to to increase the resonance frequency.
- the line material is advantageously in the form of a tapering the conductor width of the stripline ring Slit removed, being about the depth of the slit Coarse adjustment and across the width of the slot Fine adjustment of the resonance frequency takes place.
- Stripline ring is coupled stripline either shortening their length or removing them by removing material one or more places whose width tapers.
- the stripline ring 1 is one Ring resonator 1 shown.
- the Resonance frequency of this ring resonator is on the outer edge by means of a laser line material in the form of a Slit 2 removed.
- the through this slot 2 The tapering of the conductor width caused acts like an in series resonance inserted into the resonance circuit.
- the one with the Laser-made depth t of the slot 2 has one greater influence on the resonance frequency than the width w of the slot 2. Therefore, the depth t of the slot 2 a rough adjustment and across the width w of the slot 2 fine-tuned the resonance frequency.
- the slot 2 on the outside of the Stripline ring 1 is embedded, can also Slot 3 on the inside of the stripline ring 1 be provided.
- Embodiment may differ from that shown Embodiment also several slots on the inner or Outside of the line ring 1 are provided. Placed if one or more of the slots at locations of current maxima becomes thereby reducing the resonance frequency. If you choose for the or the slots where current minima on the Strip line ring 1 occur, this leads to a Increase in the resonance frequency.
- the resonance frequency of the ring resonator can achieve the material removal to change the Stripline geometry also other shapes than the side have introduced slots 2, 3. For example certain surface elements from inside the Strip line ring 1 are removed.
- the tuning of the Resonance frequency of a ring resonator also occur that with a stripline ring 4 a stripline 5th is coupled, the length or width of one or more Locations changed by removing material with a laser becomes.
- the stripline 5 by a piece 6 of length 1 has been shortened or by a slot 7 in the coupling area with the stripline ring 4 has been narrowed.
- Coupled stripline 5 can also be on one or more locations on the stripline ring 4 Material to be removed to the resonance frequency of the Adjust ring resonators.
- a varactor (capacitance) diode 8 connected to the stripline 5th a varactor (capacitance) diode 8 connected, so the resonator electronically via a control voltage U. be out of tune.
- the voting steepness can by a targeted material removal e.g. at positions 6 and 7 of the Strip line 5 can be made constant.
