Study on WPT system using a radio wave hose as a new transmission line

Abstract

In this study, we propose the use of a radio wave hose as a new transmission line and present the result of our basic study on a wireless power transmission method using microwaves. We fabricated a prototype radio wave hose by plating and processing into a resin hose, with a conductive coating and evaluated its transmission characteristics using electromagnetic field simulation and basic experimentation. Next, we constructed an experimental system for wireless power transmission using the radio wave hose and confirmed the possibility of wireless power transmission of a 100-mW class on a 5.8-GHz band.
