UAV recharging using non-contact wireless power transfer

This paper proposes application of Unmanned Aerial Vehicles (UAV)s for infrastructure inspection, such as power lines and support towers, where energy for the UAV could be gathered from the green sources, or collected from electromagnetic fields generated around the power distribution lines. This type of UAV application could, also, include monitoring buildings, agriculture areas, or water processing plants, where solar energy could be utilised. The proposal in this paper is focused on inductive and resonant inductive couplings. The concept of powering UAV, while inspecting high voltage power lines, is based on energy harvesting from electromagnetic field, at close vicinity of the conducting wires. The entire power line is acting as an infinitely long antenna.
