Dual-band low-profile antennas for intra-flight communication and data links

ABSTRACT: High speed communication channels and tactical data links are becoming increasingly important for both military and commercial applications. The need for high speed inter-flight communication and data transfer is validated by the existence of the Intra-Flight Data Link (IFDL) for the F-22 and the Multifunction Advanced Data Link (MADL) for the F-35. Unfortunately, the frequencies of operation and antenna systems for these two are unique, and thus not interoperable. This is a problem for not only legacy, but for next generation aircraft, as well. FIRST RF proposes a single low-profile, dual-frequency antenna system capable of operation with both IFDL and MADL systems. The FIRST RF solution is significantly advantageous in that it breaks from traditional, timeworn technology approaches in order to offer a lower cost, modular, simply scalable solution that also enables equivalent operation with fewer apertures around the platform; all while maintaining conformance to the platform OML, LPI and LPD functions. This system is compatible with both legacy aircraft IFDL and MADL communications and will be valid for next generation aircraft offering inter-flight communication between any mixed aircraft fleet. BENEFIT: The greatest benefit to the Air Force will be the enabling of inter-aircraft communication and data transfer between any mixed aircraft fleet. The FIRST RF technology and developmental plan offers a lower cost, modular approach that enables a much quicker design cycle. This results in hardware that may be validated on-platform sooner and at a fraction of the cost of traditional methods. The technology approach with this design will also allow for simple scalability to various platform requirements (i.e. gain, beamwidth, G/T, EIRP, SWAP). FIRST RF has identified additional commercial and military applications for this technology enabling GB/s data rates for extended range communications.
