G-band (140-220 GHz) ESAs
Nuvotronics proposes the development of G-Band (140-220 GHz) Electronically Scanned Apertures (G-Band ESAs). This program will demonstrate a multi-element electronically scanned phased array at 220 GHz that fits in a volume under 1 cubic cm. The miniature array is possible because of the revolutionary capability of PolyStrataTM technology to monolithically fabricate all of the passives of a millimeter wave aperture including: a waveguide to coaxial input transition, low loss rectangular coaxial transmission lines, multiple 2-way power splitters, and high efficiency radiating elements. Low loss phase shifters will be developed to provide rapid electronic tuning. This technology is scalable over frequency, to larger apertures, and a wide range of applications.
