The continued convergence of radar, electronic warfare and communication applications require advances in broad band phased array antennas, including both performance improvements and development of manufacturing technology. Nurad and the University of Massachusetts collaborated to design and fabricate 3:1 and 9:1 bandwidth arrays. The first array designed and tested was a 3:1 band phased array. Using lessons learned from that antenna, a 9:1 band array antenna was designed. The results showed that acceptable electrical performance is readily available and that the manufacturing of the array was vastly more complex than originally expected. This presentation discusses the electromagnetic simulation results and compares them to the measured data, while focusing on manufacturing issues and advancements.
