Metamaterial-Based Electrically Small Antenna

Spectra Research proposes an innovative approach that employs advances in numerical modeling, fragmented aperture antenna design methodologies, and metamaterials research toward the development of an advanced electrically small antenna. In the Phase I program Spectra Research will investigate the development of electrically small antennas that demonstrate improved radiation efficiency over broad bandwidths. Antenna topologies will be selected that are compatible with employment on advanced composite platforms. Innovative approaches that improve overall antenna performance while minimizing antenna profile are desired solutions for all volumetrically restricted platforms. Both Cartesian and cylindrical FDTD simulations will be employed to provide a set of design rules that then may be used to modify analytical approximations. The technical objectives of the Phase I program are to demonstrate that fragmented aperture and fragmented volume antenna designs with metamaterial augmentation can be utilized to great advantage in meeting the requirements of the solicitation. Specifically the research team will utilize our advanced antenna technologies in concert with unique metamaterial approaches to produce a common aperture antenna architecture that has broadband utility, and demonstrates superior performance over selected frequency ranges.
