Abstract :
This paper presents a phase shifter for dielectric waveguide. Phase shifting is achieved by varying the distance between the waveguide and a block of dielectric. By calculating the propagation constants of a coupled dielectric slab waveguide an approximate expression for the phase shift is given and is shown to be in good agreement with experimental results.
