Abstract

Radio Frequency Energy Harvesting (RFEH) is a technology which enables wireless power delivery to multiple devices from a single energy source. The main components of this technology are the antenna and the rectifying circuitry that converts the RF signal into DC power. RF energy harvesting holds a bright future for generating a small amount of electrical power to the circuits in wireless communication electronics devices. Wireless power transmission was developing a thought nearly a century ago. Many achievements are made till date which have made power harvesting a reality and capable of providing alternative sources of energy. This includes a resonant voltage boosting network, which provides high bias from a small signal and a rectifier that produces DC voltage. The RFEH gives very good efficiency performance, if a single antenna is considered the maximum power delivered is generally not enough to power all the elements of a system. Since the energy harvesting circuits are designed to operate with very small number of voltages and currents, they are depends on the electrical technology for obtaining high efficiency
