IRREVERSIBLE CIRCUIT ELEMENT AND MILLIMETER-WAVE HYBRID INTEGRATED CIRCUIT BOARD EQUIPPED WITH IRREVERSIBLE CIRCUIT ELEMENT

摘要

A spontaneously magnetized ferrite magnetic body is coaxially mounted on a microstrip type TMn10 resonator (n; positive integer) formed by providing a metal disk and three-fold symmetrical branches on a nonmagnetic dielectric board having a grounding conductor provided on the back thereof, the ferrite magnetic body being so arranged that the position of the node of electric field coincides with one of the above-mentioned branches.
