Abstract

This paper presents the design and analysis of different rectifier configurations using the SMS7630 Schottky diode in RF energy harvesting applications. This study focuses on achieving maximum power transfer between the antenna and the rectifier by employing a reconfigurable impedance matching circuit. The designed impedance matching circuit successfully achieved a reflection coefficient (S11) below -10dB across a range of frequencies from 1.5GHz to 5.6GHz. The performance and effectiveness of the rectifier designs and the impedance matching circuit were evaluated using advanced design system (ADS) software. The results demonstrate the feasibility and effectiveness of the proposed approach in optimising power transfer efficiency for RF energy harvesting systems within the specified frequency range.
