Abstract
Abstract A circulator comprises a cylindrical conductor housing, a disc shaped magnetic component mounted in said housing, three V-shaped inner conductors having two linear arms provided on the surface of said magnetic component, said inner conductors conjoining substantially at the center of said surface maintaining a 120-degree angle to each other, the open end of said V-shaped inner conductor being connected to the housing, and the other end of said V-shaped inner conductor being connected to an external strip line.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
110 words
A strip line type circulator comprising a cylindrical conductor housing, a disc shaped gyromagnetic component mounted in said housing, three inner elongated conductors provided on the surface of said gyromagnetic component, said inner conductors conjoining substantially at the center of said surface maintaining a 120 degree angle to each other, and means for applying a magnetic field to said gyromagnetic component, characterized in that each inner conductor is V-shaped having two linear arms with a predetermined branch angle less than 90 degrees, the open end of the V-shaped inner conductor is connected to the housing, and the other end of each inner conductor is connected to an external strip line.
