Patent ID: 7123118

Claim:
A cluster resonator, comprising: a first conducting plane; a second substantially parallel conducting plane; a cluster of vias of essentially uniform length oriented substantially normal to the conducting planes each via in the cluster comprising a first end and a second end; a first conducting pad disposed in a third plane substantially parallel and capacitively coupled to the first conducting plane and physically coupled with the vias of the cluster of vias proximate their first ends; and a second conducting pad disposed in a fourth plane substantially parallel and capacitively coupled to the second conducting plane and physically coupled with the vias of the cluster of vias proximate their second ends, wherein the vias are physically connected to only the first and second conducting pads; and wherein a combined inductance and capacitance of the cluster of vias form an electromagnetically resonant shunt circuit between the first and second conducting planes; and wherein the vias of the cluster of vias are disposed along a perimeter that defines an interior region and one or more interior vias are routed within the interior region of the cluster of vias; and wherein the interior vias comprise portions of transmission lines passing electrical signals through the cluster resonator.
