Capacitor with array of interconnects for improved self-resonant frequency and quality factor

Abstract

The technology described herein is directed towards a capacitor with a modified design (relative to standard capacitors), in which a first conductor is coupled to a second conductor via a distributed array of conducting interconnects through a dielectric that separates the conductors. The array of interconnects can be geometrically distributed. The array of conducting interconnects, not present in standard capacitors, results in capacitors with larger self-resonant frequency, e.g., having a substantially stable capacitance over a range of high radio frequencies, e.g., from one gigahertz to twenty gigahertz. This further provides an improved quality factor. The improvements resulting from the array of interconnects, facilitates more optimal surface current density. The modified capacitor provides benefits in various circuits, e.g., in a tuning element as part of an impedance matching network, in a millimeter wave frequency phase shifter for antenna elements, and so on.
