The Department of Defense (DOD) is seeking proposals for the topic of "Enhanced Radome Design" as part of the SBIR 24.1 BAA. The Navy branch is specifically interested in this technology. Radomes are used to protect antennas from environmental conditions and conceal them. The Navy requires a radome capability that provides greater filtering and aids in beam shaping. This can be achieved through the use of Frequency Selective Surfaces (FSS) to filter out undesirable frequencies and reduce electromagnetic interference. The Navy is looking for a non-reciprocal design that allows transmit power to pass through while limiting receive power. The material used must meet environmental requirements and operate within the frequency range of 4 GHz to 6 GHz. The project will be conducted in multiple phases, starting with the development of a concept and feasibility demonstration in Phase I, followed by the development and delivery of a prototype in Phase II. The work under this effort may be classified. In Phase III, the selected company will support the Navy in transitioning the enhanced radome capability to Navy use and integrate it onto the ASEA housing. This technology has potential applications in various industries, including telecommunications, aviation, and satellite communications, by improving antenna performance and reducing unwanted RF energy. The solicitation is closed, and more information can be found on the DOD SBIR website.
