Ka-Band Focusing Lens Horn Antenna
26.5 to 40 GHz, WR28
DESCRIPTION
Anteral’s Focusing Lens Horn Antennas are conical horn antennas with a double-convex
Teflon (PTFE) lens added in the aperture, in order to apply phase correction and achieve
superior focusing performance with minimum size.
The FLHA-F-WR28 model operates at the Ka-band between 26.5 and 40 GHz with a
focal length of 146 mm and a diameter beam focus of 13 mm.

APPLICATIONS
Focusing Lens Horn Antennas are especially useful when focusing beam is required withshort focal distances. Therefore, these antennas are widely used in testing and material
characterization.
Anteral also offers their Lens Horn Antennas with plano-convex lenses to exhibit highgain (>30 dB) in a very compact size which makes them optimal for radar applications,communication links or meteorological systems among others.
