Experimental Demonstration of Coexistence of Microwave Wireless Communication and Power Transfer Technologies for Battery-Free Sensor Network Systems

Abstract EN

This paper describes experimental demonstrations of a wireless power transfer system equipped with a microwave band communication function.

Battery charging using the system is described to evaluate the possibility of the coexistence of both wireless power transfer and communication functions in the C-band.

A battery-free wireless sensor network system is demonstrated, and a high-power rectifier for the system is also designed and evaluated in the S-band.

We have confirmed that microwave wireless power transfer can coexist with communication function.
