Title:
LAMINATED COIL COMPONENT AND MATCHING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2014/155873
Kind Code:
A1
Abstract:
First coil conductor patterns (11a, 11b, 11c) form one coil aperture that gives rise to magnetic flux in a first direction (for example, a direction going into the page). Second coil conductor patterns (12a, 12b, 12c) form a first coil aperture that gives rise to magnetic flux in the first direction and a second coil aperture that gives rise to magnetic flux in a second direction (direction going out of the page). In addition, the degree of coupling of the coil formed by the first coil conductor pattern and the coil formed by the second coil conductor pattern is determined by the difference in the surface area of the first coil aperture and the second coil aperture. Thus, multiple coils are disposed in proximity to each other while unnecessary coupling between the coils is suppressed.
