Abstract
A distributed resonator stripline circulator is disclosed wherein a geometrically shaped resonator pattern is deposited upon a like geometrically shaped ferrite substrate. A ground plane is deposited upon the opposing side of the substrate which includes grounding wrap-arounds that extend partially onto the resonator face of the substrate. Two such resonators are assembled, resonator patterns facing, to form a stripline circulator. The grounding wrap-arounds provide electrical connection from the top ground plane to the bottom ground plane to provide superior isolation and control of circulator loading factors.
