Dependable Wireless Powering for the Wireless Sensor Station by Using Combination of Solar Cell and Rectenna

This paper proposes an experimental evaluation result of the combination of solar cell and rectenna for wireless sensor network to realize the dependable wireless powering. 100 W class microwave power transmission (MPT) and 3000 Ix illuminance photovoltaic power generation are combined to the system. The measurement results of the output DC power were 325 mW and 160 mW for the configuration of combination of MPT and 3000 Ix photovoltaic power generation and the configuration of MPT only, respectively. The combination of the MPT and photovoltaic power generation is effective to get large DC power.
