Making Big Antennas Small: CTG’s New Flat Lens Antenna Technology (FLAT)
By Compass Technology GroupWireless and radar technologies at UHF and VHF frequencies require directive antennas for research, testing, and quality assurance. VHF/UHF wavelengths are in the range of several feet, leading to current horn antenna technology that is large and heavy - too awkward for transport or mounting without significant infrastructure. For example, a standard 0.2 - 2 GHz, dual-ridge horn weighs upwards of 30 lb. and is approximately 40” long x 35” wide x 27” tall.
Under US Air Force SBIR support, CTG recently developed a new paradigm in VHF and UHF wideband antennas: FLAT or Flat Lens Antenna Technology.
