Abstract

A stripline non-reciprocal multi-octave phase shifter which consists of a matched dielectric slab located along the first ferrite slab edge which corresponds to the magnetic wall and of lumped loads placed along the propagation direction along the same edge of the second ferrite slab. The other edge of the slabs are associated with identical composite media terminated by a lump impedance which consists of a short-circuit between the three conductors in the preferred embodiment of the invention. A high permittivity dielectric slab near the other edge of each of the ferrite slabs is preferably part of said composite media.
