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 facilitates electrical surface current flow between the first conductor and the second conductor, and determines the self-resonant frequency of the capacitor. The array (or enlarged area) 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, including millimeter wave frequencies. This further provides an improved quality factor. The improvements resulting from the technology described herein facilitate more optimal surface current density. The modified capacitor provides benefits in various circuits, e.g., in an impedance or a millimeter wave frequency phase shifter for antenna elements.
