Abstract
According to an embodiment a wireless power transmitting device, includes a power transmission antenna including patch antennas to wirelessly transmit power, and communication antennas configured to receive a communication signal from an electronic device. The wireless power transmitting device also includes a processor configured to detect a direction in which the electronic device is positioned based on the communication signal received through the communication antennas and control the power transmission antenna to transmit the power in the detected direction.
Claims16
A wireless power transmitting device, comprising:
- a plurality of patch antennas;
- a plurality of phase shifters each corresponding to the plurality of patch antennas;
- at least one amplifier corresponding to the plurality of patch antennas respectively;
- a plurality of communication antennas;
- and
- a processor configured to:
- control each of the plurality of communication antennas to receive a first communication signal generated by an external electronic device,
- detect a direction in which the external electronic device is positioned based on the first communication signal,
- control each of the plurality of phase shifters so that the plurality of patch antennas forms first sub-radio frequency (RF) waves interfering with each other in the detected direction, the first sub-RF waves each comprising a first magnitude,
- control at least one of the plurality of communication antennas to receive, from the external electronic device, a second communication signal comprising information related to intensity of a power received at the external electronic device, and
- control the at least one amplifier to adjust a magnitude of the first sub-RF waves from the first magnitude to a second magnitude based on the received second communication signal.
A method to control a wireless power transmitting device, comprising:
- receiving a first communication signal from an external electronic device;
- detecting a direction in which the external electronic device is positioned based on the first communication signal;
- controlling each of a plurality of phase shifters corresponding to a plurality of power transmission antennas of the wireless power transmitting device respectively so that each of the plurality of power transmission antennas forms sub-radio frequency (RF) waves constructively interfering with each other in the detected direction, the first sub-RF waves each comprising a first magnitude;
- receiving, from the external electronic device, a second communication signal comprising information related to intensity of a power received at the external electronic device;
- and
- controlling at least one amplifier to adjust a magnitude of the first sub-RF) waves from the first magnitude to a second magnitude based on the received second communication signal.
