<P>PROBLEM TO BE SOLVED: To provide a downsized, low-impedance magnetic resonance isolator. <P>SOLUTION: The magnetic resonance isolator includes: a ferrite 10; a connection conductor 15 that is provided on the ferrite 10 and includes openings P1, P2 and P3; a permanent magnet that applies a direct-current field to the ferrite 10; an inductor L1 that functions as a reactance element; and capacitors C1 and C2 that function as an impedance-matching circuit. A main line arranged between the first opening P1 and the second opening P2 of the connection conductor 15 does not resonate and an end of a sub-line branched from the main line defines the third opening P3. Deflected wave from the sub-line is adjusted to be shifted in phase by 90 degrees at the intersection with the connection conductor 15. The inductor L1 is connected to the third opening P3 and the capacitors C1 and C2 are connected to the first opening and the second opening, respectively. <P>COPYRIGHT: (C)2012,JPO&INPIT |
