Wireless power transmission apparatus, electronic apparatus for receiving power wirelessly and operation method thereof

A method in an electronic device, comprising:

• receiving at least part of an RF wave of a first beam width formed from a wireless power transmitter via at least one antenna of the electronic device,
• obtaining, via at least one sensor of the electronic device, information about approach of the electronic device to a body portion of a user,
• transmitting the information to the wireless power transmitter via a communication circuit of the electronic device, and
• receiving, via the at least one antenna of the electronic device, at least part of an RF wave, directed at the electronic device by the wireless power transmitter, whose beam width has been adjusted from the first beam width to a second beam width based on, at least, the transmitted information indicating approach of the electronic device to the body portion.

A non-transitory computer readable medium storing instructions executable by at least one processor to cause an electronic device to perform:

• receiving at least part of an RF wave of a first beam width formed from a wireless power transmitter via at least one antenna of the electronic device,
• obtaining, via at least one sensor of the electronic device, information about approach of the electronic device to a body portion of a user,
• transmitting the information to the wireless power transmitter via a communication circuit of the electronic device, and
• receiving, via the at least one antenna of the electronic device, at least part of an RF wave, directed at the electronic device by the wireless power transmitter, whose beam width has been adjusted from the first beam width to a second beam width based on, at least, the transmitted information indicating approach of the electronic device to the body portion.
