Classification: CPC H | IPC H

Claim 17:
18. A shelving-mounted wireless-power-transmitting and receiving system, comprising:
a shelving-mounted wireless-power-transmitting device, wherein the shelving-mounted wireless-power-transmitting device is configured to transmit RF power waves to a wireless-power harvester device that is integrated in a small form-factor device; and
the wireless-power harvester device integrated in the small form-factor device, including:
a stamped metal harvesting antenna configured to harvest radio frequency (RF) power waves, the stamped metal antenna formed into a meandering shape, wherein:
the meandering shape includes a predetermined number of turns,
a first end of the meandering shape is a free end positioned within free space of a housing of a small form-factor device,
a second end of the meandering shape is coupled to a PCB that includes electrical components for operating and powering the small form-factor device, the PCB configured to operate as a ground plane for the stamped metal antenna, and
an intermediate portion, disposed between the first end and the second end, of the meandering shape coupled to power-conversion circuitry that is separate from the PCB, the power-conversion circuitry configured to convert the one or more of the RF power waves harvested by the stamped metal harvesting antenna into usable energy for charging a battery of the small form-factor device or for powering the small form-factor device.
