Patent ID: 6952044

Claim:
A capacitor comprising: a plurality of layers in each of first, second and third spaced apart portions, said first portion positioned between said second and third portions; a first capacitive plate formed in said first portion of a first layer of said plurality of layers; a dielectric material; first and second elements of a second capacitive plate formed in said second and third portions, respectively, or a second layer of said plurality of layers and separated by the dielectric material; and a third element of said second capacitive plate coupled between the first and second elements and formed in said first portion of a third layer of said plurality of layers; wherein a dielectric separation between the first capacitive plate and the third element of the second capacitive plate comprises air, thereby defining at least one air bridge structure, and the first capacitive plate and the second capacitive plate are formed as a coupled transmission line structure that defines an interdigital capacitor which obtains its primary capacitance from the coupling of energy between a plurality of edges of the first capacitive plate and the first and second elements of the second capacitive plate.
