Microwave-Powered Wireless Sensor Network

Abstract

This thesis describes the design and construction of a wireless sensor network that harvests power for operations from a rectifying antenna. This project represents a proof-of-concept for future systems that will someday operate without the need of batteries or other conventional methods of storing power. This project was completed as a senior design project in the Engineering program at The University of Arizona for Drs. Marcellin and Xin. This project developed the described system from concept to an operational test in the laboratory that demonstrated the system working as expected while being powered by wireless energy transmission. Node input voltage reached a steady state near 0.8 V, and remained so for the entirety of the test. This project was pursued as a group effort.
