2014 - Integrated RF-DC converter and PCB antenna for UHF wireless powering applications [Relazione in Atti di Convegno]
Vincetti, Luca; Maini, M.; Scorcioni, Stefano; Larcher, Luca; Bertacchini, Alessandro; Tacchini, Alessandro

In this work, a broadband differential RF-DC CMOS converter realized in CMOS 130 nm technology with a customized PCB antenna with inductive coupling feeding for RF energy scavenging is presented. Experimental results show that output DC voltage higher than 1V from 800MHz to 970MHz can be obtained with a load of 1kohm.

2013 - Single-Ended Broadband Antenna for Radiofrequency Energy Harvesting [Relazione in Atti di Convegno]
Vincetti, Luca; Maini, M.; Bompani, M.; Larcher, Luca; Scorcioni, Stefano; Bertacchini, Alessandro; Grossi, D.; Tacchini, Alessandro

A single-ended broadband UHF antenna with high inductive input impedance for radiofrequency energy harvesting is here presented. It consists of a small feeding loop and a conical radiating monopole. A prototype has been fabricated on a FR4 substrate and tested. Experimental results show a -3dB power transmission bandwidth of about 130MHz (860MHz−990MHz).
