Gaussian Optics Lens Antennas
SAG-1441544002-06-S1
-
Gaussian optics lens antennas are offered with either a circular or rectangular waveguide interface. While Gaussian optics lens antennas with a rectangular waveguide interface can only support linear polarization, models with a circular waveguide interface can support various polarization types including horizontal, vertical, left-handed circular, and right-handed circular polarization for broader applications. Gaussian optics lens antennas are designed and constructed to offer high efficiency, low side lobes and a rugged mechanical configuration. A corrugated feed horn and dielectric lens allow these antennas to form well-defined Gaussian beams. Additionally, the dielectric lens provides phase error corrections and serves as a radome to protect from environmental conditions.
