1. A wireless power transmitting device, comprising:
- a power transmission antenna comprising patch antennas;
at least one communication antenna; and
a processor, wherein the processor is configured to;
receive, through the at least one communication antenna, a plurality of communication signals from an external electronic device,detect a direction in which the external electronic device is positioned based on at least one of time of reception and phase of each of the received plurality of communication signals, andtransmit a wireless power to the external electronic device by controlling each of the patch antennas so that sub-radio frequency (RF) waves constructively interfere with each other in the detected direction of the external electronic device.
