Broadband, lightweight, low profile passive phased array

Innovative approaches that improve overall antenna performance while minimizing antenna profile are desired solutions for all volumetrically restricted platforms. This is especially critical for advanced intelligence, surveillance, and reconnaissance (ISR) platforms that are expected to provide extended time on station. Spectra Research proposes an innovative approach to accomplishing the program objectives by employing advances in fragmented aperture antenna designs, in concert with the extensive Spectra Research capability in designing specialized antennas, to develop solutions for a unique ultra broadband phased array. Both Cartesian and cylindrical FDTD simulations will provide a set of design rules that then may be used to modify analytical approximations. Once this is done, the design rules will be applied to intelligently optimize a candidate antenna design in the presence of specialized materials. In Phase II of this program, an advanced antenna design will be implemented based on lessons learned and sponsor guidance and a prototype demonstration will be constructed and measured.
