Abstract
A ferroelectric phase shifter in the form of a coplanar waveguide and a method of fabrication thereof in which a ferroelectric film and a high temperature superconductor film are deposited onto a substrate in of a number of configurations. The high temperature superconductor material is biased in order to vary the dielectric constant of the ferroelectric material. Changing the dielectric constant enables varying the amount of phase shift of a wave applied to the phase shifter.
