Abstract
We present an RF energy harvesting system where two distinct passive UHF RFID microchips provide different tag IDs to detect low and high states of the harvester's charge storage. This enables the backend system to acknowledge when the harvesting system is ready for advanced power consuming operations. Overall, we were able to read the separate IDs of the tag at the distance of 3 m from an RFID reader that is emitting the regulated EIRP of 3.28 W and charging harvester's storage capacitor to 0.625 V through 8.7 dBi harvesting antenna.
