Anteral’s Lens Horn Antennas (LHA) are conical horn antennas with a plano-convex Teflon (PTFE) or High-density Polyethylene (HDPE) lens added in the aperture, in order to apply phase correction and achieve superior performance with minimum size.
They are designed to cover the frequency range of 8 to 170 GHz in 14 bands with 30 dB nominal mid-band gain. Anteral optimizes all designs to show not only high gain, but also low VSWR (< 1.3) and low side lobes. Moreover, custom bands and gain values can be requested. Anteral offers LHAs with linear or circular polarization.
LHAs are specially useful when high gain is required with the minimum size. Therefore, these antennas are widely used in radar applications, communication links and meteorological systems among others. New cutting-edge space applications include LHA’s for MiniSat, MicroSat, NanoSat and CubeSat communications.
Anteral also offers their Focusing Lens Horn Antennas (LHA-F) with double-convex lenses to exhibit very well define focusing beams with short focal distances which makes them optimal for testing and material characterization.
