RF energy harvesting rectenna
A rectenna cell you can chain in series or parallel, so ambient RF gets harvested off whatever antenna you plug in.
Description
A harvester built as one board is stuck with one antenna and one output voltage. Change either and you are redesigning it.
I built the harvester as a repeatable cell instead. Cells wire in series or parallel to reach whatever voltage the load wants. I tested the rectifier against several ultra-wideband antennas to see how much of the ambient energy each one actually handed over.
A harvesting stage that is not tied to one antenna or one voltage.
