A Study of Received Power in Distributed Wireless Power Transfer System

Recently, microwave wireless power transfer (MWPT) for loT devices has been researched. However, there are some problems with high-power microwave transmission such as effect on the human body, interference to other devices and cost. In this study, we propose a distributed MWPT system that enables to reducing of transmitted power density and improving the received power level. By the simulation and experiment, the effectiveness of the distributed MWPT system has been shown.
