Abstract
A phase shifter employing a voltage variable dielectric material to add controlled phase delay in a ridged-waveguide section. The dielectric material has the property that its dielectric constant varies with changing electric field applied to the material. The dielectric material fills the ridge gap between the two waveguide ridges. An electrode is disposed within the dielectric material, and is connected to a variable voltage source to establish a transverse electrical field within the dielectric material. By varying the voltage, the magnitude of the field is varied, thereby allowing the phase delay of electromagnetic signals propagating through the waveguide section to be changed.
