Abstract
A wireless power transmission apparatus according to various embodiments may comprise a plurality of patch antennas, a communication circuit, and a processor. The processor may be configured to perform a control to form an RF wave of a first beam width via the plurality of patch antennas, receive, from an electronic apparatus, via the communication circuit, sensing data for at least one of a movement of the electronic apparatus or an orientation of the electronic apparatus, and adjust a beam width of the RF wave formed by the plurality of patch antennas from the first beam width to a second beam width at least on the basis of the received sensing data.
