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.

Standard Gain Horn Conical Lens antennas
Elva’s SLHA series of standard gain horn lens antennas cover the frequency range of 18 to 220 GHz in ten waveguide bands. They can be issued with rectangular or circular waveguide. Lens technology significantly allows decreasing mechanical sizes of horns and correcting beam for the best performance. These horns are ideal solution for measurement gain of other antennas, short range radars and radiometers.

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.

Rotman Lens Designer
Rotman Lens Designer (RLD) is a software tool for the design, synthesis, and analysis of Rotman Lenses and their variants. It is based on Geometrical Optics combined with the classical Rotman Lens design equations. It is intended for rapid development and analysis of Rotman Lenses given several physical and electrical input parameters. RLD generates the proper lens contours, transmission line geometry, absorptive port (dummy port) geometry, provides an approximate analysis of performance, and generates geometry files for import into Remcom's XFdtd® for further analysis and fabrication.
