Abstract: A computing device includes a charging coil for producing a charging current when placed in a magnetic field of a wireless power transmitter. A wireless charging operating frequency is associated with wireless charging of a battery of the computing device by the charging coil and the wireless power transmitter. An electrically conductive substrate has a plurality of gaps for reducing eddy currents when the electrically conductive substrate is disposed between the charging coil and the wireless power transmitter during charging of the battery. A plurality of filters each electrically bridge a respective one of the gaps. Each filter attenuates signals within a range of frequencies including the wireless charging operating frequency.
