Abstract
A wireless power transmission apparatus includes patch antennas which form an RF wave; a memory storing electromagnetic wave distribution maps corresponding to transmission conditions for transmitting the RF wave; and a processor configured to determine a position of an electronic device and a position of a living body, determine a transmission condition which transmits the RF wave which causes an electromagnetic wave having a size not exceeding a first threshold value to be applied to a position of the living body while being beam-formed at a position of the electronic device, using at least a portion of the electromagnetic wave distribution maps, and generate the RF wave with the determined transmission condition using the patch antennas, each electromagnetic wave distribution map indicating the size of electromagnetic waves at one or more points around the wireless power transmission apparatus when the RF wave is formed by each of the transmission conditions.
