Efficient Broadband RF Energy Harvesting for Wireless Sensors
نویسندگان
چکیده
This paper presents an approach to wireless power delivery and subsequent power management for low-power batteryless sensors. Broadband multifrequency rectenna arrays which independently receive and rectify two orthogonal wave polarizations provide DC power with decreased variations in a multipath environment. The DC power extracted from 2-18GHz electromagnetic radiation is managed by high efficiency power processing circuitry. Experimental results are presented for an integrated switched capacitor power converter realized in a fullydepleted silicon on insulator (FD-SOI) process.
