专利汇可以提供Resonance control in interdigital capacitors useful as dc breaks in diode oscillator circuits专利检索，专利查询，专利分析的服务。并且A modified stripline interdigital capacitor has slots coupled into the capacitor gap. These slots provide reactive loading to the slot transmission line formed by the gap. They are positioned and dimensioned to shift the frequency of the slot line resonance so that it is out of a selected frequency band without affecting the capacitance of the structure. This interdigital structure may be used in diode oscillator circuits to provide a dc block for isolating the input and output from the diode bias.，下面是Resonance control in interdigital capacitors useful as dc breaks in diode oscillator circuits专利的具体信息内容。

权利要求

1. An interdigital capacitor comprising, a stripline having a first and second section of conductive material, each section having a set of fingers protruding from one end, said sections being positioned to interdigitate the fingers of one section with the fingers of the other so that a continuous gap is created between the conductive sections, the gap forming a resonant transmission line, at least one slot cut into one of the conductive sections and coupling into the gap, said slot being dimensioned to be non-resonant in a predetermined frequency band and being dimensioned and positioned to shift the frequency of resonance of the transmission line out of said predetermined frequency band.

2. An interdigital capacitor comprising: a stripline having a first and second section of conductive material, each section having a set of fingers protruding from one end, said sections being positioned to interdigitate the fingers of one section with the fingers of the other so that a continuous gap is created between the conductive sections, the gap forming a resonant slot transmission line, CHARACTERIZED IN THAT said capacitor further comprises means for reactively loading the transmission line formed by the gap to shift its frequency of resonance, said reactive loading means including at least one non-resonant slot cut into one of the conductive sections and coupling into the gap.

3. An interdigital capacitor as claimed in claim 2 wherein said transmission line is capable of resonating at a first frequency determined by the length of the gap and said slot is non-resonant at said first frequency and is dimensioned and positioned to inductively load the slot transmission line to create an effective length of the transmission line greater than the length of the gap so that the transmission line resonates at a second frequency lower than the first frequency.

4. An interdigital capacitor as claimed in claim 2 wherein said one slot is coupled to the gap substantially at the voltage null point of the standing wave pattern of the resonance being shifted.

5. An interdigital capacitor as claimed in claim 2 wherein said one slot is coupled into the center of the gap to shift a half-wave resonant frequency.

6. An interdigital capacitor as claimed in claim 2 wherein said one slot is coupled to the gap at a point off the center of the gap to shift a full-wave resonant frequency.

7. An interdigital capacitor as claimed in claim 2 wherein said means for reactively loading the transmission line includes a pair of slots cut into one conductive section and symmetrically displaced from the center line of that section to shift a full-wave resonant frequency.

8. An interdigital capacitor as claimed in claim 2 wherein one of said conductive sections is broader than the other and said slot is cut into the broader section.
