Abstract :
A dielectric waveguide structure, containing an NiZn ferrite as phase-shifting medium is described. By applying a longitudinal static magnetic field to the ferrite, a reciprocal phase shift is obtained. Broadband characteristics are achieved by tapering the ferrite. Experimental results in the frequency range of 60¿90 GHz for the phase shift and insertion loss of the device are presented.
