Anteral’s Focusing Lens Horn Antennas (FLHA) are conical horn antennas with a double-convex Teflon (PTFE) or high-density polyethylene (HDPE) lens added in the aperture, in order to apply phase correction and achieve superior focusing performance with minimum size.
Anteral optimizes all designs to show not only the best focusing performance, but also low VSWR (< 1.3) and low side lobes. Moreover, custom focus performance can be requested.
Focusing Lens Horn Antennas are specially useful when focusing beam is required with short focal distances. Therefore, these antennas are widely used in testing and material characterization.
Anteral also offers their Lens Horn Antennas (LHA) with plano-convex lenses to exhibit high gain (>30 dB) in a very compact size which makes them optimal for radar applications, communication links and meteorological systems among others.
