Millimeter wave microstrip phase shifter

摘要: A microstrip reciprocal phase shifter is provided comprising a rectangular ferrite rod having an upwardly sloping ramp member at one end thereof and downwardly the other thereof. The members are made of dielectric waveguide constant substantially same as rod. disposed on surface substrate lower than ground plane Input output sections conductor placed in axial alignment with members. plate less top another section two electrically interconnected input conductors. helical coil arranged to surround produce unidirectional magnetic field along longitudinal axis thereby cause act Reggia-Spencer type shifter.
