摘要

本文提出了从环境射频(RF)源收集能量的可行性研究。通过功率谱密度的计算和接收功率的测量，对一个普通郊区的环境射频能量进行了初步评估。结果表明，从800 MHz频段移动电话基站(BS)获得的-25dBm接收功率中位数平均比数字电视广播强13dB。设计并测试了多级RF-DC转换电路样机。实验结果表明，在普通郊区，一个1.0 F的双层电电容器可以在3900分钟内充电到320 mV。我们确认了从郊区环境射频源中收集能量的可能性，并阐明了未来能量收集系统中设备存在的问题。

Energy harvesting from ambient RF sources

This paper presents a feasibility study of energy harvesting from ambient radio frequency (RF) sources. A preliminary assessment of the ambient RF energy was carried out by calculation of power spectrum density and measurement of received power in a common suburban area. The results showed that the median value of received power obtained -25dBm from 800 MHz band mobile telephone base station (BS) was averagely 13dB stronger than that from Digital TV broadcasting. A prototype multi-stage RF-DC conversion circuit was designed and tested. Experimental results showed that a 1.0 F electric double layer capacitor can be charged up to 320 mV in 3900 minutes at common suburban area. We confirm that the possibility of energy harvesting from ambient RF sources in suburban area, and clarify the problems in devices for the future energy harvesting systems.
