	1	Ultra-Low Power High-Efficiency UHF-Band Wireless Energy Harvesting Circuit Design and Experiment显示文摘In this paper,an ultra-low power high-efficiency ultra-high frequency(UHF)-band wireless energy harvesting circuit based on the diode SMS7360 is designed and experimentally demonstrated,being operated in all released Global System for Mobile Communications(GSM)bands in China(GSM900 band:0.87-0.96 GHz and GSM1800 band:1.71-1.86 GHz).This UHF-band wireless energy harvesting circuit can harvest energy at 0.87-0.96 GHz and 1.71-1.86 GHz bands simultaneously in outdoor or indoor environment.The test results show that a radio-frequency(RF)-to-direct-current(DC)conversion efficiency in the range of 20%-63.2% is obtained for an available input power of-22 dBm to 1 dBm in GSM900 band and that in the range of 13.8%-55.5% is achieved for an available input power of-22 dBm to 3 dBm in GSM1800 band.The harvested RF energy is converted into DC energy and be stored in a 6.8 mF super capacitor through the energy management circuit.This super capacitor’s capacity is more than 20 mJ,which can meet the demand of high-speed broadband wireless communication transceivers.This ultra-low power highefficiency UHF-band wireless energy harvesting circuit could be used to achieve the low power wireless sensor network node(tag).
