    Abstract: The present disclosure pertains to wireless chargers. In one embodiment, a 2×2 array of conductive coils produces magnetic fields. Adjacent coils receive current having different directions to cancel magnetic fields around a periphery of the array. A wireless charging platform may include at least four such coils. Regions between and above the coils may include magnetic fields approximately parallel to the surface of the platform so that electronic devices may be charged while standing up during operation by a user with reduced exposure to magnetic radiation. An electronic device may also be placed flat on each coil for charging.

    Abstract: An aspect of this disclosure is an apparatus for transmitting power wirelessly. The apparatus comprises a detection circuit and a processor. The apparatus also includes a power amplifier driving an antenna circuit of flexible antenna(s) configured for wireless power transfer. The processor determines that at least one measured variable of the power amplifier falls outside of a corresponding threshold range, indicative of a deformation of a physical shape of one of the flexible antennas or indicative of misalignment of the flexible antennas from a power receiver. The processor further commands the power amplifier to transition to a first power mode from a second power mode based on the determination that at least one of the measured variables falls outside of the corresponding threshold range. The antenna circuit in the first power mode transmits power at a power level less than the power level in the second power mode.
