RF Energy Harvesting and Remote Powering at 900MHz and 2.4GHz

Résumé

This work presents the development of two low cost RF energy harvesters dedicated to the ISM bands. The rectifiers exhibit respectively a maximum of power efficiency of 47% and 33% at 900MHz and 2.4GHz. Focusing on the sensitivity, the harvesters provide a 1V output voltage at 3m with a radiated power of 27dBm at 2.4GHz, and 11m with a radiated power of 30dBm at 900MHz. The demonstration of energy scavenging is further proposed by the remote powering of a clock (0.9V/5uA) during the download of a video with a cellphone in GSM mode, and then the data broadcasting in bluetooth mode by a tablet.
