High-power microwave antennas are essential for defense industry radar systems, cyber warfare, and power transmission. The US Department of Defense a SBIR proposal specifying the need for a high-power phased-array microwave antenna for the US Air Force.

Vivaldi antennas, invented in 1978 by Peter Gibson, have been widely adopted for radar applications due to their high bandwidth and gain performance. Considerable amounts of research exists on designing Vivaldis for different applications ranging from radar to communications. Using antenna theory and past research, a new Vivaldi antenna was designed to meet the requirements mandated by the DoD research contract.

This project consists of the research, design, and fabrication of an all-metal, high-power Vivaldi antenna. The design was modeled and simulated using Ansys HFSS to observe the idealized performance. After meeting the desired specifications through simulation and optimization, the antenna design was fabricated via an investment casting process.
