    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.

    Abstract: A wireless power transmitter configured to wirelessly transmit power to an electronic device is provided. The wireless power transmitter includes a power transmission antenna including a plurality of patch antennas for wirelessly transmitting power, a sensor, and a processor, wherein the processor may be configured to create a first clutter map representing a reflection characteristic of an object positioned around the wireless power transmitter based on, at least, first data obtained by the sensor during a first period, store the first clutter map, compare a difference between the first clutter map and second data obtained by the sensor during a second period with data contained in the first clutter map, create a second clutter map corresponding to the second period based on a result of the comparison, determine a position of an organism using the second data and the second clutter map, and control the power transmission antenna such that a magnitude of the RF wave is less than a predetermined value based on the position of the organism.
