摘要：
Systems and methods may provide for a wireless charging device having a concave-shaped charging platform defining a charging area. The wireless charging device may include a three-dimensional transmitter coil, and at least one additional transmitter coil having a non-uniform spacing within the concave-shaped charging platform to reduce magnetic field variations associated with the three-dimensional transmitter coil.
