Abstract
A three port microwave circulator in a slot line transmission medium. Two slot lines are formed which extend from two ports of the circulator in a collinear alignment through a coupler region, and are joined at a power combining junction to provide a single transmission line to the third port of the circulator. A ferrite slab overlays the coupler region. The ferrite is saturated with a static magnetic field, applied by a magnet, along a direction of signal propagation. The circulator can be integrated into a flared notch radiator element to provide separate transmit and receive ports.
