Wideband Antenna Apertures for Integration with DARPA ACT Common Module Technology(1000-359)

SI2 Technologies, Inc. (SI2) proposes to design and develop a low-cost, wideband, conformal antenna array that can be integrated with beamforming common modules separately developed in the DARPA ACT program. We will leverage our proprietary antenna array technology, validated on a variety of previous programs, to design an antenna array that can cover the full bandwidth for the Phase II DARPA ACT beamforming modules. The proposed antenna array will be designed to be conformal to an attritable airborne platform and will be combined with modules from the ACT program to demonstrate an integrated system.In the proposed Phase II program, the antenna array design will be refined and optimized for the ACT bandwidth and to interface with the ACT beamforming modules. The performance of the antenna system will be validated through the manufacture and test of both an initial planar prototype subarray (Base program), as well as a prototype full array (Option program) that is conformal to the outer mold line of an attritable airborne platform. The prototypes will be subjected to full RF characterization, resulting in TRL/MRL 6 for the integrated antenna array assembly.
