  • Reconfiguration microstrip transmission line network
    Patent number: 5495211
    Abstract: The present invention discloses a reconfigurable microstrip transmission line network having a microstrip circuit consisting of an RF ground plan separated from a transmission layer by a dielectric layer. The transmission layer comprises a silicon material responsive to a plurality of excitation sources. The excitation sources generate excitation beams which upon interacting with the surface of the transmission layer actuate a conductive pathway. By alternately actuating and deactuating the excitation sources and varying the excitation beams, the configuration of the microstrip transmission line network upon the transmission layer may be reconfigured as desired.
