  • Publication number: 20210143686
    Abstract: A wireless power receiving circuit module includes a first base, a second base, electronic components, a power receiving coil, and a ground conductor pattern. The number of layers of the second base is different from that of the first base, and the second base does not overlap with the first base in a plan view and shares a predetermined dielectric layer with the first base. The electronic components are mounted on a first main surface of the first base. The power receiving coil is formed in the second base. The ground conductor pattern is disposed on a second main surface side in the first base and overlaps with the electronic components.

  • Publication number: 20210143685
    Abstract: A planar-type wireless power-receiving circuit module includes a planar ground conductor, a substrate, a power-receiving coil, and a magnetic sheet. The planar ground conductor has a cavity in the middle section thereof. The substrate is disposed on a first main surface of the planar ground conductor. The substrate includes dielectric layers stacked on top of each other in a manner so as to form electronic circuitry. The power-receiving coil is electrically connected to the electronic circuitry and is disposed in the cavity. The magnetic sheet overlaps the power-receiving coil when the planar ground conductor is viewed in plan. The magnetic sheet is part of a path of magnetic flux passing through the power-receiving coil and is disposed on a first main surface of the power-receiving coil.
