WIPO Patent Application WO/2018/100975
Kind Code:
A1
Abstract:
A combined coil module is provided with a first flat coil, a second flat coil, and a magnetic sheet in which a magnetic circuit of the first flat coil and a magnetic circuit of the second flat coil are formed. The first flat coil is used in wireless communication. The second flat coil is used in power transmission for non-contact charging. The magnetic sheet comprises one type of magnetic body. The magnetic sheet has a first magnetic circuit formation section in which the magnetic circuit of the first flat coil is formed, and a second magnetic circuit formation section in which the magnetic circuit of the second flat coil is formed. The magnetic permeability of the first magnetic circuit formation section differs from the magnetic permeability of the second magnetic circuit formation section.
