PRINTED CIRCUIT FOR WIRELESS POWER TRANSFER

摘要

Printed circuit includes a substrate body having a plurality of substrate layers stacked along a Z-axis. Each substrate layer is substantially planar and extends along an XY plane. The X-, Y-, and Z-axes are mutually perpendicular. The printed circuit also includes a Z-field coil that is coupled to the substrate body and has a conductive trace that is parallel to the XY plane. The printed circuit also includes an X-field coil having conductive trace segments that are coupled to the substrate body and parallel to the XY plane. The X-field coil includes conductive paths that extend substantially parallel to the Z-axis. The conductive paths interconnect the trace segments. The Z-field coil and the X-field coil are configured to generate respective vector components of a magnetic field or have a voltage induced therein by a magnetic field.
