Triple band rectifier design for RF energy harvesting in wireless sensor networks

Abstract

The atmospheric energy harvesting is a vital innovation to the achievement of wireless sensor systems. In day to day life, different form of energy resources is present better communication. Among those energy sources, Radio Frequency (RF) energy is one of the best sources with broad coverage of signals from various wireless communication systems. Collecting a wide recurrence band RF signals are valuable to support the aggregate level of energy. In this paper, the design of triple bands rectifier to rectify the harvested RF energy from cellular system frequency bands and Wi-Fi sources available in atmospheric environment is presented. Advanced Design System (ADS) simulator was utilized to design a 4-stage voltage multiplier RF energy harvesting circuit. This voltage multiplier makes use of Agilent diode HSMS-2850 for rectification purpose. The exploratory outcome demonstrates that the proposed design can gather more power than the power obtained from a single band.
