Funding will support the project team's small-scale research and development of a long-distance wireless power transfer (WPT) 4 meter (m) phased array antenna with over 1 kilowatt of radio frequency power transmitting 200m to a 4m receiving antenna array with minimum 70 percent end-to-end efficiency from source to delivered direct current (DC) for the purpose of connecting energy generation with demand.

Funding will support the project team's small-scale research and development of a long-distance wireless power transfer (WPT) 4 meter (m) phased array antenna with over 1 kilowatt of radio frequency power transmitting 200m to a 4m receiving antenna array with minimum 70 percent end-to-end efficiency from source to delivered direct current (DC) for the purpose of connecting energy generation with demand. Specifically, the project team will (1) develop simulation models to analyze and validate system component performance, (2) develop, test, and validate WPT system components, (3) integrate system components and test in lab to achieve performance metrics, (4) conduct outdoor testing of final system to meet project performance metrics. If successful, this project will result in a WPT system that would improve the DC to DC efficiency transmission at high power and significant distance by a factor of approximately 4 as compared to the previous highest efficiency system, improving electrical resiliency and flexibility without the need for fixed cabling and energy storage assets, meeting the growing needs of rising domestic energy use and thereby increasing U.S. energy security
