Patent ID: 7560648

Claim:
A twisted wire pair comprising: a first wire and a second wire, the first and second wires being twisted about one another; the first wire including a first conductor, the first wire also including a first polymeric insulator surrounding the first conductor, the first polymeric insulator defining a plurality of first insulator channels having lengths that run along the length of the first conductor, each of the plurality of first insulator channels having an open side that faces toward the first conductor, each of the plurality of first insulator channels including a first material therein that has a dielectric constant that is lower than the dielectric constant of the first polymeric insulator; and the second wire including a second conductor, the second wire also including a second polymeric insulator surrounding the second conductor, the second polymeric insulator defining a plurality of second insulator channels having lengths that run along the length of the second conductor, each of the plurality of second insulator channels having an open side that faces toward the second conductor, each of the plurality of second insulator channels including a second material therein that has a dielectric constant that is lower than the dielectric constant of the second polymeric insulator.
