Abstract

A wireless charging transmitter and its method are used to charge an electronic device with a receiving coil. The wireless charging transmitter includes: a charging module including a transmitting coil electromagnetically coupled to the receiving coil; and a comb combination of a shield and a planar dipole antenna array. The comb combination of shield and planar dipole antenna array includes a plurality of dipole antennas, and each dipole antenna includes a plurality of comb antenna sections.

Description

technical field [0001] The present invention relates to a wireless power transmitter and method thereof, and more particularly to a wireless power transmitter with a combined faraday shield and dipole antenna array and method thereof. Background technique [0002] The charging of the electronic device can be connected to the charging device by a wire or by a rechargeable battery inside the electronic device to provide the required power. However, the wired charging method will cause inconvenience due to the limited length of the charging wire. [0003] Therefore, inductive charging (also called wireless charging), which is realized by electromagnetic induction, is becoming more and more common in electronic devices. Wireless power transfer systems send power from a transmitter to a receiver without going through any wired connections. [0004] However, electromagnetic interference (EMI) is a major problem, which is detrimental to the performance of electronic devices. The...
