Abstract:
A coaxial circulator having ferrite members to which a static magnetic field is applied disposed at a junction of a Y-shaped strip conductor, the coaxial conductor comprising:a dielectric substrate; an inner pattern of the Y-shaped strip conductor provided on a center of an upper surface of the dielectric substrate; and ground patterns provided on the upper surface and a lower surface of the dielectric substrate along a periphery of the conductive inner pattern and electrically connected to each other via a plurality of through holes in the dielectric substrate, the substrate being sandwiched by an upper block and a lower block, the ferrite members being provided adjacent to both the upper side and a lower side of the substrate so as to ground the ground patterns to the upper and lower block surfaces, wherein the Y-shaped strip conductor and the ground patterns provided on the upper surface of the dielectric substrate lie in a common plane.
