Abstract A slot-line circulator having a ferrite disc either coated on or embedded and integral with a dielectric substrate on one surface of which there is provided a narrow gap in a conductive coating to form a slot line adapted to propagate microwave energy. The energy-propagating slot line extends substantially halfway across the surface of the ferrite disc at which point the conductors forming the slot-line gap are branched outwardly to form an angle of substantially 120*. Respective conductive coatings are provided parallel to and spaced from each of the branched conductors to form two slot-line arms, or channels, which connect to the wave-propagating slot line to form a Y-junction. The width of the conductive coatings and the spacing or gap therebetween for each of the Y-junction channels is identical. A currentcarrying latching wire is provided through the center of the ferrite disc and is connected to a reversible DC source of to establish a circumferential DC magnetic bias field in the ferrite in either of two directions.
A slot-line circulator comprising a ferrite disc having a central aperture, a slot-line Y-junction on one surface of said disc and symmetrical about said aperture, and a current-carrying latching wire extending through said aperture and separate from said disc.
