Patent number: 8074346Abstract: The methods described herein provide for a radio frequency micro-electromechanical systems switch having two or more resonant frequencies. The switch can be configured as a capacitive shunt switch having a deflectable member coupled between two electrodes over a transmission line. A first insulator can be located between one of the electrodes and the deflectable member to form a capacitive element. The deflectable member can be deflectable between an up-state and a down-state, the down-state capacitively coupling the deflectable member with the transmission line. The degree by which the deflectable member overlaps the first insulator can be adjusted to adjust the capacitance of the capacitive element and the resulting resonant frequency.Type: GrantFiled: September 4, 2007Date of Patent: December 13, 2011Assignee: The Regents of the University of CaliforniaInventors: Jiangyuan Qian, Hung-Pin Chang, Bedri A. Cetiner, Mark Bachman, Franco DeFlaviis, Guann-Pyng Li

Patent number: 7884689Abstract: Systems and methods are provided that facilitate the formation of micro-mechanical structures and related systems on a laminated substrate. More particularly, a micro-mechanical device and a three-dimensional multiple frequency antenna are provided for in which the micro-mechanical device and antenna, as well as additional components, can be fabricated together concurrently on the same laminated substrate. The fabrication process includes a low temperature disposition process allowing for deposition of an insulator material at a temperature below the maximum operating temperature of the laminated substrate, as well as a planarization process allowing for the molding and planarizing of a polymer layer to be used as a form for a micro-mechanical device.Type: GrantFiled: July 3, 2006Date of Patent: February 8, 2011Assignee: The Regents of the University of CaliforniaInventors: Bedri A.
