Gaussian Optics Lens Antennas by ELVA-1 is worthy choice for mainly near-field applications involving radars, plasma diagnostics, remote sensing, surveillance, communications systems, etc. The available datasheet below contains information on frequency choice, gain, pattern diagram, outline drawings and more.
The Gauss Optics Lens Antennas are available in various gain levels for each subband. The typical gain levels are within 25 to 55 dBi depending on frequency and size. ELVA-1 series GOLA antennas are available in 12 subbands from 18 to 400 GHz. The on-shelf products are up to 235 GHz, the subband of 235 to 400 GHz could be supplied upon request.
The shaped pieces of microwave-transparent material are used in the GOLA antenna systems to bend and focus the radio waves by refraction, as an optical lens does if for light. These antennas are much more efficient compare to conventional conical horn antennas: for the same size a gain improvement cold be +10 dB much with a very narrow beamwidth of about 1 degree.
Applications
• Plasma diagnostics
• Radars and remote sensing
• Material properties research
• Communication systems
• Surveillance systems
Often GOLA antennas are used for near-field applications such as plasma diagnostics and exploring of material properties.
