Abstract: A leakage power processing method of an electronic device including a first conductive pattern that sends and receives a communication signal associated with a communication function, a second conductive pattern that is arranged adjacent to the first conductive pattern and sends and receives a power signal used for charging, and a communication hardware interface electrically connected with the first conductive pattern is provided. The leakage power processing method includes determining, by a processor of an electronic device, whether a specific power signal is induced through the second conductive pattern and forming, by the processor of the electronic device, a closed loop including the first conductive pattern if the specific power signal of a specific magnitude or greater is induced.

Abstract: A power transmitting unit is provided. The power transmitting unit includes a signal generator configured to generate a signal of a first frequency band for wireless charging, a power generation circuit configured to generate a modulation signal for modulating the signal of the first frequency band generated by the signal generator, and amplify a transmit power of the signal of the first frequency band based on voltage supplied from the outside of the power transmitting unit, a power transmission circuit configured to transmit the amplified transmit power to a power receiving unit via a first antenna, a second antenna configured to receive information about a charging state from the power receiving unit through a second frequency band, and a control circuit configured to control a duty and frequency of the modulation signal based on the charging state.
