Conclusion RF energy harvesting is an increasingly popular research topic that has gained a lot of attention since the introduction of RFID, autonomous wireless sensors, and wearable devices. RF energy harvesting fundamentals such as wave propagation, antenna efficiency, and antenna-rectifier interface have been presented.
RF energy refers to the electrical energy generated by harvesting RF signals, both ambient and dedicated, emitted by a transmitter.
RF energy harvesting architecture is a mechanism that provides a sustainable energy supply with easy availability compared to other energy harvesting methods. It can help meet the energy requirements of IoT-oriented energy-constrained networks.
Since energy harvesting circuits are designed to operate with relatively small voltages and currents, they rely on state-of-the-art electrical technology for obtaining high efficiency. This review provides a summary of radio frequency (RF) power harvesting technologies in order to serve as a guide for the design of RF energy harvesting units.
In RF energy harvesting, a rectifying antenna, or rectenna, is a crucial circuit architecture. It receives RF signals in a single frequency or a range of different frequencies and converts them into DC power.
The major characteristics that distinguish RF energy harvesting from other energy sources are reliability and affordability. Reliability is defined as gathering enough energy to allow sensor nodes in any sensor network to operate continuously at any time and in any location.
