Antenna-Based RF Energy Harvesting
Several 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. The applicability of harvesting RF energy from the environment is to drive low-power devices without using any batteries. The systems operating on batteries eventually run out of them which then need charging. In any of the cases cited above, the devices can be operated sans the usage of connectors, battery panels, and cables, rendering these devices portable while in operation. This paper also focuses on parameters to design the system model, different frequency ranges that can be utilized, and the circuitry required for translating low voltage output obtained to a high voltage output for numerous applications.
