Abstract/Summary
Wireless power beaming from space and energy harvesting were once stories of science fiction, until now. Wireless power transmission (WPT) is a field continually in development to provide energy in situations where energy transfer through wires is impractical or unfeasible. This engineering discipline abandons the use of wire technology for the energy transfer between the power source and a distant device. While various forms of WPT exist, our project focuses on transmission through means of radio frequency (RF), utilizing electromagnetic waves to power devices. Furthermore, WPT technology primarily assists in the elimination of a physical connection between devices, and it allows power transmission from a central hub, which can be located at variable distances away from the devices it is charging. Furthermore, WPT technology can address issues of not having a power source in remote areas, where satellite technology can be used to beam energy to remote locations on Earth’s surface. Additionally, WPT can be extended into energy recycling and energy harvesting from various radio frequency (RF) sources. This project created a WPT system using a three-layer double-loop transmitarray. Beam focusing was successfully accomplished using the array, with an introduced 5 dB of power gain at the receiver within a region of 0.3 meters to 1 meter. The peak gain was 5.8 dB at 0.61 meters and a minimum of 2.2 dB at 2.059 meters, forming a bell-shaped curve characteristic of beam focusing.
