Classification: CPC H | IPC H

Claim 16:
17. A small form-factor device, comprising:
wireless-power harvester, 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 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.
