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.
