A -- RFI for 3-D Fractal Antennas, RF Oscillators and Transmitters

The Air Force Research Laboratory's Munitions Directorate is seeking white papers through a Request for Information (RFI) focused on the development of compact, rugged antenna technologies designed to enable real-time fuze status transmission during underground target penetration. The primary emphasis is on innovative 3-D and 2-D fractal antenna designs that can be integrated into realizable geometries such as cones, hemispheres, and cylinders, operating within the 50-500 MHz frequency range. Additionally, there is interest in very compact radio frequency oscillators and transmitters capable of outputting more than 100 watts, all of which must withstand intense shock loads and other harsh environmental conditions. This RFI is intended solely for information gathering and planning purposes and does not constitute a formal solicitation or commitment from the government. Interested parties are encouraged to submit preliminary design concepts and white papers showcasing their technologies that meet the stringent durability and operational requirements outlined. The technical point of contact is Dr. Alex Cash at AFRL/MNMI, located at Eglin Air Force Base, Florida, who can be reached by phone or email for further inquiries. The RFI was posted in April 2002 under the reference number MNK-02-0012.
