Abstract

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 decreased. In this paper we present the efficiency analysis and optimization of multistage matching networks at a single frequency using lumped components. Considering complex source and load impedances at each stage of the network, we show that it is possible to obtain
better results than prior art.
