SI2 TECHNOLOGIES, INC — Department of Defense SBIR Phase II: SI2 Technologies, Inc. (SI2) proposes to design and develop a multifunction conformal ante

Description

SI2 Technologies, Inc. (SI2) proposes to design and develop a multifunction conformal antenna system for UHF Flight Termination System (FTS), L-band Global Positioning System (GPS), and S-band Telemetry applications for the SM-3 family of missiles and other platforms. To reduce the depth of protrusion, axial length, and weight of the multifunction antenna while maintaining wide bandwidth and high efficiency, SI2 will employ an innovative concept based on novel cavity loading. The Phase II program is built upon the previous work conducted by SI2 in Phase I in developing highly efficient, low profile conformal antennas. The advantages of SI2"s multifunction antenna include high efficiency, low profile, weight reduction and wide bandwidth. In Phase II, the conformal multifunction antenna concept will be refined using high fidelity numerical modeling and simulation tools. The multifunction antenna will be integrated with a composite guidance section for further weight savings. The performance of the antenna system will be optimized and validated through the manufacture and testing of a full scale prototype hardware demonstrator, resulting in TRL 6 for the antenna system.
