PURPOSE:To reduce the lateral width of a circulator by bending >=3 center conductors to left and right at an optional angle in a plane. CONSTITUTION:On a soft magnetic body 12, a ferrite core 6b is mounted via a shield plate 15b. On the core 6b, three center conductros 13a-13c are provided. The conductors 13a and 13c are bent to left and right at halfway points and set parallel to each other. Consequently, the lateral width of a circulator is reduced substantially. Another ferrite core 6a is mounted on those conductors and covered with another shield plate 15a, on which a permanent magnet 3 is arranged. Thus, the small-sized and inexpensive circulator is obtained. |
