A reflective termination coplanar waveguide phase shifter including a substrate, a tunable dielectric film having a dielectric constant between 70 to 600, a tuning range of 20 to 60%, and a loss tangent between 0.008 to 0.03 at K and Ka bands positioned on a surface of the substrate, first and second open ended coplanar waveguides positioned on a surface of the tunable dielectric film opposite the substrate, microstrip line for coupling a radio frequency signal to and from the first and second coplanar waveguides, and a connection for applying a control voltage to the tunable dielectric film. <IMAGE>
