A wireless charging transmitter is provided for charging an electronic device having a receiver coil. The wireless charging transmitter includes a charging module, including a transmitter coil electromagnetically coupled to the receiver coil, and a comb-shaped combination of shielding and planar dipole antenna array. The comb-shaped combination of shielding and planar dipole antenna array includes a plurality of dipole antennas; each of the dipole antennas includes a plurality of comb-like antenna portions.

Wireless charging transmitter and method thereof

A comb-structured shielding layer and a wireless charging transmitter thereof are provided. The wireless charging module is connected to a power source, has at least one wireless charging coil and at least one comb-structured shielding layer, and is configured to convert alternative current power from the power source to H-field electromagnetic radiations, and wirelessly charges an electronic device. The comb-structured shielding layer is disposed between the wireless charging module and the target electronic device and configured to allow the H-field electromagnetic radiations pass through. The comb-structured shielding layer includes a first area and a second area. The first area is electrically connected to a reference electric potential. The second area is electrically connected to the reference electric potential through the first area, and is configured to shield the E-field electromagnetic radiations but allow the H-field electromagnetic radiations pass through the comb-structured shielding layer.
