Abstract : A dielectric waveguide reciprocal ferrite phase shifter is provided for use in a dielectric waveguide transmission line. The phase shifter is comprised of a length of ferrite of the same cross-sectional dimension as that of the dielectric waveguide and in fact becomes a section of the transmission line. The length of ferrite bears a thin plastic layer on its top and bottom surface and metal plates on each piece of plastic. The length of this multilayer structure then has a wire coil wrapped around in order to provide a.d.c. magnetic biasing field along the length of the ferrite thereby enabling magnetization of the ferrite resulting in a reciprocal phase shift or change in electrical length within the structure.
