1. A transmission line phase shifter comprising:

  • a signal conductor;

    a high-permittivity dielectric self-supporting layer overlying said signal conductor, said high-permittivity dielectric self-supporting layer including a high-permittivity dielectric material; and

    a controller for controlling the interaction of the permittivity of the high-permittivity dielectric element with the signal conductor, said controller including an electromechanical system for controlling the position of said high-permittivity dielectric self-supporting layer with respect to said signal conductor by moving said high-permittivity dielectric self-supporting layer toward and away from said signal conductor.
