This paper presents an analysis of matching circuit with rectifier for RF energy harvesting. The matching circuit has a significant influence to improve the efficiency of RF-DC conversion. In this paper, comparative analysis of rectifier efficiency is performed, particularly the rectifier with-and without-matching circuit. The analysis is conducted using ADS simulation version 2011, to determine the output power as well as the efficiency of the rectifier. The results show the rectifier with-matching circuit produced higher efficiency about 72%, compared to the rectifier without-matching circuit which is only achieved 20% of the efficiency. The effects of tuning the matching circuit upon the rectifier efficiency had been studied. In this paper, the parametric studies of the effect of short circuit and open circuit stubs tuning are performed to determine the efficiency of the rectifier. The results show matching circuit after tuning produced higher efficiency compared to matching circuit before tuning. This study is useful to provide an insight on the optimum technique to design RF energy harvesting.
