ENHANCED GAIN ANTENNA SYSTEMS EMPLOYING FRACTAL METAMATERIALS

摘要

Systems and techniques are described that provide for enhanced gain and radiation characteristics of antennas. The systems and techniques employ layers or cards of fractal plasmonic surfaces to provide gain to the antennas. The fractal plasmonic surfaces each include a close-packed arrangements of resonators having self-similar or fractal shapes, which may be referred to as “fractal cells.” The cards can be held by a frame adapted to fit an antenna. The FPS cards can provide benefits for gain, field emission, directivity, increased bandwidth, power delivery, and/or heat management. One or more dielectric layers or cards may be used to enhance gain and/or directivity characteristics.
