Lens Antenna

Source: QuinStar Technology, Inc.
QuinStar Technology's QLA series lens antennas are available with apertures ranging from 2 to 18 inches (50-457.2 mm) for any frequency in the 12-220 GHz range. These antennas consist of a lens which is fed (illuminated) by a specially-designed feed horn. They have inherently low sidelobes, particularly in comparison to Cassegrain reflector antennas, as there is no blockage of the main beam by a subreflector or feed structure...

QuinStar Technology's QLA series lens antennas are available with apertures ranging from 2 to 18 inches (50-457.2 mm) for any frequency in the 12-220 GHz range. These antennas consist of a lens which is fed (illuminated) by a specially-designed feed horn. They have inherently low sidelobes, particularly in comparison to Cassegrain reflector antennas, as there is no blockage of the main beam by a subreflector or feed structure.

Specially designed lenses when combined with high performance feeds produce high gain, precise beam patterns and efficiency comparable to the best reflector antennas, even at high millimeter wave frequencies. They operate over a fairly wide frequency range, which is generally determined by the characteristics of the input feed horn.

Standard antennas are focused at infinity (far field). However, custom designs focused at a finite range, generally 2 to 300 inches (0.05 to 10 meters) from the lens, can be provided. They can also be produced at a fairly low cost in large quantity. In addition, the antenna housing can be used as an enclosure for other components, system electronics or the entire system.

Characteristics:

  • Low Sidelobes
  • High Gain and Efficiency
  • Broadband
  • Low Cost
  • Fresnel Lens Option
