PROBLEM TO BE SOLVED: To reinforce the mechanical and electrical performance of a multielement concatenated circulator and reduce the handling and setup cost. SOLUTION: The circulator is equipped with a metallic casing which includes a plurality of concatenated junctions for providing a plurality of nonreversible transmission paths between the signal ports on a network and a cover where the junctions are arranged. Each of the plurality of junctions is equipped with an oval permanent magnet, a multiferrite component including two elliptic ferrite elements, a dielectric constant medium arranged between the ferrite elements, and a plurality of conductors put between the ferrite elements. The multielement concatenated circulator is constituted so as to include the oval permanent magnet and the elliptic ferrite components used for two or more junctions of the circulator, whereby the multielement concatenated circulator achieves reinformed performance together with reduced stock and manufacture cost.
