Designing a Compact and High-efficiency Rectifier with a Multilayer Substrate Filter

We proposed a multilayer substrate filter composed of a microstrip line and substrate integrated waveguide (SIW) for the output filter of the rectifier to reduce the size of the rectifier circuit in the previous study. In this paper, we improve the multilayer substrate filter and design the filter for the rectifier input filter. Moreover, we place these filters in the rectifier, simulate its rectification characteristic and compare it with the conventional rectifier. As a result, we achieve downsizing the circuit area and improving its efficiency.
