Abstract: A system includes a charging station and one or more receiving devices receiving wireless power from the charging station. The charging station includes an orientation adaptable antenna (OAA). The OAA may generate a magnetic field component parallel to the plane of the OAA to charge devices oriented at 90 degrees with respect to the OAA. The OAA may generate a magnetic field along different directions within the plane parallel to the OAA. The OAA may be able to adjust the direction of the field to couple to devices with antennas in different orientations. The OAA may further produce a magnetic field normal to the plane of the OAA. The OAA may adjust the relative strengths the various directional components of the magnetic field to align the field normal to the antennas of the receiving devices in up to three dimensions, simultaneously charge receiving devices in different orientations, or both.
