Ultra Wideband Advanced Antenna Systems for Air Vehicles (1000-150)

SI2 Technologies, Inc. (SI2) proposes to design and develop several conformal antennas for UHF flight termination , L-band data link, S band telemetry and C band tracking beacon systems for the Navy Strike Weapons. In addition, SI2 proposes anti jamming protection for S and C band antennas using frequency selective surfaces (FSS). To improve the wideband performance and significantly reduce the thickness of the antenna systems, SI2 will employ an innovative concept based on reactively coupled microstrip dipoles. The Phase II program is built upon the previous work conducted by SI2 in Phase I in developing highly efficient conformal antennas. The advantages of SI2 antennas include high efficiency, low profile, weight reduction and wide bandwidth. In Phase II, the conformal flight termination systems antenna concept will be refined using high fidelity numerical modeling and simulation tools. The performance of the antenna system will be simulated and validated through the manufacture and testing of a full scale prototype hardware demonstrator. The conformal antennas will be fabricated using Direct Write technology. The prototype will be tested on a Strike Weapon to demonstrate the antenna RF performance. In Phase II Option, SI2 will design and fabricate FSS for antijamming protection.
