Patent ID: 7170374

Claim:
A self-sustaining center-anchor microelectromechanical switch comprising: transmission lines formed on a substrate at a predetermined gap and having an input portion and an output portion; ground lines formed at both sides of the transmission lines; a dielectric-moving plate formed over the substrate and including a switching unit that electrically connects the transmission line during short-circuit operation; anchors having a self-sustaining center-anchor formed on a center line of the transmission lines to support the dielectric-moving plate to the substrate; and upper electrodes located in an upper portion of the dielectric-moving plate different than where the switching unit is located and serving as a driving electrode to the ground line, wherein the switching unit is operated by a bending of the dielectric-moving plate generated by a voltage difference applied to the upper electrode and the ground line, and switches the transmission lines; wherein the self-sustaining center-anchor is located in the gap between the transmission line having the input portion and the transmission line having the output portion.
