Abstract
The disclosure provides a wireless power transmitting device and a method for detecting an approaching object by the wireless power transmitting device. According to the disclosure, a wireless power transmitting device may comprise: a power amplifier, a transmission resonator including a coil, and configured to receive an electrical signal corresponding to a first frequency, which is output through the power amplifier, and to form a magnetic field by the received electrical signal corresponding to the first frequency to transmit power, an antenna configured in a shape corresponding to any one side of a symmetrical axis of a split ring resonator (SRR) antenna, disposed adjacent to the transmission resonator, and configured to receive a signal corresponding to a second frequency, a sensing circuit configured to sense at least part of the signal corresponding to the second frequency transmitted to the antenna, and a controller configured to identify whether a human body approaches, based on a signal sensed through the sensing circuit. A first terminal of the sensing circuit may be connected to a first portion of the antenna, and a second terminal of the sensing circuit may be connected to the coil of the transmission resonator.
