    摘要： The invention is a new device that will improve the radio link quality for low power wireless devices. An example application is for low power, miniaturized wireless sensor nodes that are statically deployed in a slowly varying environment or that have limited mobility. The device is a reconfigurable antenna that is novel in that it operates with very low (zero-order) energy in contrast to existing system that required both significant computational and DC power.

    摘要： The present invention describes nano-scale fabrication technique used to create a sub-micron wide gap across the center conductor of a coplanar waveguide transmission line configured in a fixed-fixed beam arrangement, resulting in a pair of opposing cantilever beams that comprise an electro-mechanical switch. Accordingly, a nanometer-scale mechanical switch with very high switching speed and low actuation voltage has been developed. This switch is intended primarily for application in the RF/microwave/wireless industry.

    摘要： The present invention provides a method and apparatus for a monolithic device utilizing cascaded, switchable slow-wave CPW sections that are integrated along the length of a planar transmission line. The purpose of the switchable slow-wave CPW sections elements is to enable control of the propagation constant along the transmission line while maintaining a quasi-constant characteristic impedance. The device can be used to produce true time delay phase shifting components in which large amounts of time delay can be achieved without significant variation in the effective characteristic impedance of the transmission line, and thus also the input/output return loss of the component. Additionally, for a particular value of return loss, greater time delay per unit length can be achieved in comparison to tunable capacitance-only delay components.
