ABSTRACT:
An RF-actuated microelectromechanical systems (MEMS) switch for use with switchable RF structures such as antennas and reflectors is disclosed. An antenna within each MEMS switch module is coupled to a circuit that provides a trigger voltage based on an RF control signal received at the antenna. The trigger voltage output of the circuit is used as the control the MEMS switch. This allows arrays of MEMS switch modules to be actuated by remotely generated radio frequency signals thus alleviating the need for running metallic conductors or optical fibers to each MEMS switch. Frequency response characteristics, phasing, reflectivity, and directionality characteristics may be altered in real-time.
