Abstract

In this paper, a novel synthesis technique for dual-frequency rectifier for ambient RF energy harvesting is proposed. For the first time, a fully distributed version of dual-frequency resistance compression network (RCN) is introduced. The proposed RCN utilizes the dual- frequency characteristic of the c-type coupled lines terminated into real impedance. The design technique is fully analytical based on closed-form design equations. Extensive simulations have been carried out to illustrate the proposed idea. The obtained results outperform the earlier reported lumped element network and provides a minimum 10% improvement in the RF-to-DC conversion efficiency at -20 dBm input power. The proposed technique can potentially serve as a starting point for the dual-frequency RF rectifier design.

结合耦合线的双频射频能量收集整流器的新型合成
本文提出了一种用于环境射频能量采集的双频整流器合成新技术。首次提出了全分布式的双频电阻压缩网络(RCN)。所提出的RCN利用了c型耦合线端接成实阻抗的双频特性。设计技术是基于封闭式设计方程的完全解析式设计。已经进行了大量的模拟来说明所提出的想法。所得结果优于先前报道的集总元件网络,在-20 dBm输入功率下,rf - dc转换效率至少提高10%。提出的技术可以潜在地作为双频射频整流器设计的起点。
