CIRCULATOR Russian patent published in 1997 - IPC

FIELD: SHF equipment. SUBSTANCE: invention can find use in decoupling of circuits in SHF equipment. Circulator includes Y branching of rectangular waveguides in H plane in which center cylindrical recess is made in center of one of walls. Magnetized ferrite disc with dielectric permittivity $$$ is placed on base of recesses. Inserted dielectric plate in the form of disc or equilateral triangular prism mounted on wall of Y branching with overlapping of cylindrical recess diminishes both concentration of electric field in magnetized ferrite disc and on edge of cylindrical recess and factor of merit of waveguide resonator: cylindrical recess - magnetized ferrite disc, which results in increased electrical strength and expansion of band of working frequencies. In this case dielectric permittivity $$$ of dielectric plate and its thickness are selected in agreement with formulas $$$, $$$, where $$$ is wave length. EFFECT: increased electric strength and expanded band of working frequencies. 1 dwg
