Patent ID: 8320100

Claim:
A varactor element, comprising: a dielectric layer; a pair of signal electrodes disposed in an interior portion of the dielectric layer, each signal electrode extending in a first direction, and disposed so that exterior ends of the signal electrodes are exposed on opposed exterior surfaces of the dielectric layer, and the signal electrodes extend toward one another to the interior of the dielectric layer so that opposed interior ends of the signal electrodes face each other with a first distance therebetween; and a pair of control electrodes disposed in the interior portion of the dielectric layer, each control electrode extending in a second direction perpendicular to the first direction, and disposed so that exterior ends of the control electrodes are exposed on opposed exterior surfaces of the dielectric layer, and the control electrodes extend toward one another to the interior of the dielectric layer so that opposed interior ends of the control electrodes face each other with a second distance therebetween.
