  • Electrically controlled phase shifter
    Patent number: 4575697
    Abstract: A microwave phase shifter for use in waveguide transmission line employs a piezoelectric cantilevered bimorph member mounted on the waveguide and a thin wafer of dielectric material mounted on the free end of the cantilever above a slot in the waveguide. Voltages applied to the bimorph member cause this member to distort so as to insert the wafer into the waveguide slot and alter the phase of the microwave signal being transmitted.
