Multistage Complex-Impedance Matching Network Analysis and Optimization

open access: yesIEEE Transactions on Circuits and Systems II: Express Briefs, 2016
Some systems like RF energy harvesters have power transfer efficiency as one of the most important specifications. Therefore, the efficiency of the matching network, which affects the entire system's efficiency, plays an important role. When the impedance transformation factor between the antenna and its load is high, the matching network efficiency is
