Abstract

A Wireless Power Transfer (WPT), especially the WPT via microwaves, can drive a wireless communication system like a wireless sensor without battery. However, both n the WPT and in the wireless communication, we use radio waves and we have to consider suppression of interference and coexistence of both wireless systems We propose pulse-WPT for ZigBee sensors in order to suppress the interference to the wireless sensors. We show results of development of a suitable rectenna, rectifying antenna, and experimental results of coexistence of the WPT and the wireless sensors.
