  • Microstrip phase shifter
    Patent number: 6621377
    Abstract: A phase shifter includes a substrate, a first electrode positioned on a surface of the substrate, a tunable dielectric layer positioned on a surface of the electrode, a microstrip positioned on a surface of the tunable dielectric layer opposite the substrate, an input for coupling a radio frequency signal to the microstrip, an output for receiving the radio frequency signal from the microstrip, and a connection for applying a control voltage to the electrode. In an alternative embodiment, a second electrode can be positioned on the surface of the substrate and separated from the first electrode to form a gap positioned under the microstrip.
    Type: Grant
