Title:
MULTILAYER COIL ELEMENT, ANTENNA MODULE, AND WIRELESS-COMMUNICATION MODULE
Document Type and Number:
WIPO Patent Application WO/2015/129597
Kind Code:
A1
Abstract:
This multilayer coil element (10) comprises a laminate (20), and said laminate (20) contains wound, planar first and second coil conductors (311 and 321) and a planar magnetic-shield member (40). The first coil conductor (311) and the second coil conductor (321) are laid out such that, viewed in the direction in which the winding axis extends, parts of the winding regions of said coil conductors coincide. The magnetic-shield member (40) is located between the first coil conductor (311) and the second coil conductor (321) in the direction in which the winding axis extends. The magnetic-shield member (40) is shaped so as to coincide with a first region in which the first coil conductor (311) and the second coil conductor (321) coincide with each other and not coincide with at least part of a second region in which the first coil conductor (311) and the second coil conductor (321) do not coincide with each other.
