Abstract

A wireless power transmitting device is provided. The wireless power transmitting device includes a patch antenna, and a transmission/reception processing circuit configured to output a first signal to the patch antenna during a first period, and process a second signal output from the patch antenna during a second period, wherein the patch antenna is configured to transmit a transmission wave using the first signal, and output the second signal to the transmission/reception processing circuit using a reception wave.

Claims20

Dependent claims

A wireless power transmitting device comprising:

a power source;
a patch antenna;
a transceiver circuit;
and
a processor configured to:
control the transceiver circuit to transmit, through the patch antenna, a first signal provided from the power source during a first period,
control the transceiver circuit to receive, through the patch antenna, a second signal based on a reflection of the first signal during a second period,
determine whether a target device is detected based on the second signal, and
in response to determination that the target device is detected, control the transceiver circuit to transmit, through the patch antenna, power to the target device,
wherein the first period does not overlap with the second period.

7 more elements

A wireless power transmitting device comprising:

a power source;
a plurality of patch antennas;
a transceiver circuit;
and
a processor configured to:
control the transceiver circuit to transmit, through a first part of the plurality of patch antennas, a first signal provided from the power source, and
control the transceiver circuit to receive, through a second part of the plurality of patch antennas, a second signal based on a reflection of the first signal,
determine whether a target device is detected based on the second signal, and
in response to determination that the target device is detected, control the transceiver circuit to transmit, through at least a part of the plurality of patch antennas, power to the target device.
