摘要： A vertical comb actuator radio frequency (RF) micro-electro-mechanical system (MEMS) switch. The RF MEMS switch includes a substrate; first and second signal lines spaced at a predetermined interval from each other and deposited on an upper surface of the substrate; an actuator positioned over the first and second signal lines when viewed from the upper surface of the substrate and spaced at a predetermined interval from the first and second signal lines; and a fixing portion positioned over the actuator when viewed from the upper surface of the substrate, wherein the fixing portion permits the actuator to come in contact with the first and second signal lines when a predetermined driving voltage is applied. Thus, it is possible to prevent the actuator from sticking to the substrate. In addition, the RF MEMS switch can be operated with a low voltage and insertion loss and power loss can be reduced.

摘要： A MEMS switch includes a substrate, at least one signal line and at least one electrode formed on the substrate, and a moving beam disposed in a spaced-apart relation with respect to the substrate above the substrate so as to be connected with or disconnected from the signal line according to an operation of the electrode. The moving beam includes at least one body, and at least one support to support the body. The body has a modulus of elasticity larger than that of the support. The MEMS switch prevents the moving beam from being stuck and increases a contact force generating between the moving beam and the signal line, thereby enabling a signal to be stably transmitted.

摘要： A MEMS (Micro Electro Mechanical Systems) switch actuated by electrostatic and piezoelectric forces, includes a substrate; a first contact point positioned in a predetermined first area on an upper surface of the substrate; a support layer suspended at a predetermined distance from the upper surface of the substrate; a second contact point formed on a lower surface of the support layer; a first actuator operative to move the support layer in a predetermined direction using an electrostatic force; and a second actuator operative to move the support layer in a predetermined direction using a piezoelectric force. The first actuator is used to turn on the MEMS switch. The second actuator can be used together with the first actuator to turn on the MEMS switch or can be separately used to turn off the MEMS switch. As a result, a stiction can be prevented from occurring between contact points.
