Examination of Matching Circuit Impedance on High-Efficiency Operating RF-DC Conversion Circuits
Kensuke Kobayashi, Kazuhiro Fujimori (OU) WPT2020-32
Abstract (in Japanese) (See Japanese page) 
(in English) Highly efficient rectenna and RF-DC conversion circuit are required for power transmission and energy harvesting in the microwave band. Since a diode with non-linear characteristics is used for the RF-DC conversion circuit, it is difficult to theoretically design a highly efficient RF-DC conversion circuit unless the diode is modeled. Therefore, the authors have investigated automatic design by genetic algorism (GA). As a result of performing automatic design multiple times, it was found that the impedance of the matching circuit required for the RF-DC conversion circuit generally converges to a specific value when the input power and load are fixed. We are also experimentally examining the relationship between the impedance of this matching circuit and the impedance of the diode.
