Lens Antennas
A lens antenna is a directional antenna that uses a shaped piece of microwave-transparent material to bend and focus microwaves by refraction, as an optical lens does for light.[1] Typically it consists of a small feed antenna such as a patch antenna or horn antenna which radiates radio waves, with a piece of dielectric or composite material in front which functions as a converging lens to collimate the radio waves into a beam.[2] Conversely, in a receiving antenna the lens focuses the incoming radio waves onto the feed antenna, which converts them to electric currents which are delivered to a radio receiver. They can also be fed by an array of feed antennas, called a focal plane array (FPA), to create more complicated radiation patterns.

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.

FLAT Antennas
CTG recently developed a new paradigm in linearly-polarized antennas called the Flat Lens Antenna Technology or ‘FLAT’. These antennas have directivities similar to conventional dual-ridge antennas, but in a much lighter and “flatter” package. They can be used as a direct replacement for conventional horns for a wide variety of applications. They are made using composites technology so are also rugged and are ideal for both indoor and out-door applications.

Lens Corrected Antennas
Lens corrected antennas are offered with either a circular or rectangular waveguide interface. While lens corrected 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. These antennas are designed and constructed to offer high efficiency, low side lobes and a rugged mechanical configuration. In general, lens corrected antennas are ideal for achieving gain levels of up to 30 dB with moderate side lobe rejections. Additionally, its dielectric lens provides phase error corrections and serves as a radome to protect from environmental conditions.
