Description
Anteral’s Lens Horn Antennas are conical horn antennas with a TEFLON lens added in the aperture, in order
to apply phase correction and achieve superior performance with minimum size. The lenses are designedwith optimized hyperbolic profiles to reduce the aberration to the minimum. They are designed to cover thefrequency range of 8 to 170 GHz, offering 30 dB nominal gain with a very compact size. Anteral designs allLens Horn Antennas to show not only high gain, but also low VSWR (< 1.22) and low side lobes.

Applications
Lens Horn Antennas are especially useful when high gain is required with the minimum size. Therefore,
these antennas are widely used in radar applications, communication and meteorological systems among
others. Moreover, the very well defined radiated plane wave makes these antennas also very suitable formaterial characterization.

Additional Notes
Anteral offers custom designs to show any desired gain.
All designs are optimized to offer the maximum gain with the minimum size.
The performance of all devices is checked before delivery.
Extended performance datasheet is available if customer requires. Ask for more information.
