Claims

[Scope of utility model registration request]

A joint conductor formed approximately in the center of the upper surface of the ferrite plate, and a matching transformer conductor bent along the outer periphery of the joint conductor except for the vicinity of the connection with the joint conductor. , a stripline circulator comprising a ground conductor in close contact with the lower surface of the ferrite plate, and a magnet disposed outside the joint conductor and/or the ground conductor, wherein the thickness of the ferrite plate is equal to or smaller than the joint part. A stripline fist circulator characterized in that a portion where the conductor is formed is thick and a portion where the matching transformer conductor is formed is thin.
