Abstract: A reconfigurable adaptive wideband antenna includes a reconfigurable conductive substrate for dynamic reconfigurablility of the frequency, polarization, bandwidth, number of beams and their spatial directions, and the shape of the radiation pattern. The antenna is configured as a reflect array antenna having a single broadband feed. Reflective elements are electronically painted on the reconfigurable conductive surface using plasma injection of carriers in high-resistivity semiconductors.

Abstract: A microelectronic mechanical systems (MEMS) switch includes a vane formed over a substrate for electrically coupling an input line to an output line formed on the substrate. The vane includes flexible hinges, which support the vane from the input line and allow the vane to rotate about a pivot axis. The substrate includes pull-down and pull-back electrodes to actuate the MEMS switch. The pull-back electrode allows the present invention to overcome stiction effects.

Abstract: A microelectronic mechanical system (MEMS) switch includes a vane (122) formed over a substrate for electrically coupling an input line (102) to an output line (104) formed on the substrate. The vane includes flexible hinges (126), which support the vane from the input line and allow the vane to rotate about a pivot axis. The substrate includes pull-down (112) and pull-back (110) electrodes to actuate the MEMS switch. The pull-back electrode allows the present invention to overcome stiction effects.
