Abstract

This paper presents the antenna to enhance DC output of RF energy harvesting system under weak signal reception environment. To select candidate sites and base stations for RF energy harvesting system, we discuss expected reception power level by a simple line-of-sight propagation model and the specification of currently used base stations. Under this site condition, this paper presents a voltage-boosting antenna consisting of a folded dipole antenna with high input impedance and rectifier circuit tuned for it. A theory of voltage-booting and a circuit design procedure are presented for FM radio signals.
一种用于射频能量收集的升压天线
提出了在微弱信号接收环境下提高射频能量采集系统直流输出的天线。为了选择射频能量收集系统的候选站点和基站,我们通过一个简单的视线传播模型和当前使用的基站规范讨论了预期的接收功率水平。在这种现场条件下,本文提出了一种由高输入阻抗的折叠偶极子天线和整流电路组成的升压天线。提出了调频信号电压启动的原理和电路设计方法。
