LAMINATED COIL COMPONENT AND MATCHING CIRCUIT

摘要

In a laminated coil component, first coil conductor patterns define a coil opening that generates a magnetic flux in a first direction, second coil conductor patterns define a first coil opening that generates a magnetic flux in the first direction, and a second coil opening that generates a magnetic flux in a second direction. A difference in area between the first coil opening and the second coil opening determines a degree of coupling of the coil defined by the first coil conductor pattern and the coil defined by the second coil conductor pattern. This provides a close proximal arrangement of a plurality of coils proximally while significantly reducing or preventing unnecessary coupling between the coils.

1. A laminated coil component comprising:
a conductor pattern including a first coil conductor pattern and a second coil conductor pattern; at least one insulating layer on which the conductor pattern is provided; and at least one coil defined by a plurality of the conductor patterns of the insulating layers that are laminated on each other; wherein the first coil conductor pattern defines a coil opening that generates a magnetic flux in a first direction; the second coil conductor pattern defines a first coil opening that generates a magnetic flux in the first direction and a second coil opening that generates a magnetic flux in a second direction opposite to the first direction; and the coil opening of the first coil conductor pattern, in a plan view, overlaps a plurality of the coil openings including the first coil opening and the second coil opening of the second coil conductor pattern.
