This paper discusses harvesting of low-power density incident plane waves for electronic devices in environments where it is difficult or impossible to change batteries and where the exact locations of the energy sources are not known. As the incident power densities vary over time and space, distributed arrays of antennas with optimized power ...

2018 International Conference on Smart City and Emerging Technology (ICSCET), 2018
Electronic devices have different power requirements. The devices which operate continuously require continuous power supply. Some devices operate periodically such as WSN node, which are powered on for particular time and remains in sleep mode otherwise. These nodes require power in $\pmb{\mu} \mathbf{W}$ to $\mathbf{mW}$ , The power density of the

2011 IEEE International Conference on Microwaves, Communications, Antennas and Electronic Systems (COMCAS 2011), 2011
Harvesting or scavenging the RF(Radio Frequency) energy, better known by its engineering name — “RF energy Scavenging”, is one of the emerging fields, with very good research opportunities. It is a technique, by which, we utilize the RF energy present in the external atmosphere, by scavenging, and convert it into an useful electrical output for driving

Antenna-Based RF Energy Harvesting
2019Several useful forms of energy exist around us such as solar, wind, RF radiation, and piezoelectric. The objective of this paper is to throw light on energy-harvesting systems using radio frequency. The required RF energy is usually transmitted from various sources such as mobile towers, base stations, TV/Radio broadcasting stations, and Wi-Fi routers.
