摘要

This paper presents the design of an efficient energy harvesting system for energizing wireless sensor nodes using the electromagnetic radiation from cell towers in the CDMA and GSM bands. A new multiband microstrip monopole antenna with circular polarization and impedance 377ohms is designed to grab the ambient RF energy efficiently. The antenna structure is simulated using electromagnetic software Computer Simulation Technology. A seven stage voltage doubler is used as RF to DC conversion module. The voltage doubler is simulated using SPICE. The results show that the rectifying antenna system generates the desired voltage to energize the wireless sensor nodes.
