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.

Cassegrain Antennas
-
In telecommunications and radar, a Cassegrain antenna is a parabolic antenna in which the feed antenna is mounted at or behind the surface of the concave main parabolic reflector dish and is aimed at a smaller convex secondary reflector suspended in front of the primary reflector. The beam of radio waves from the feed illuminates the secondary reflector, which reflects it back to the main reflector dish, which reflects it forward again to form the desired beam. The Cassegrain design is widely used in parabolic antennas, particularly in large antennas such as those in satellite ground stations, radio telescopes, and communication satellites.

DAS Antennas
-
In-Building Distributed Antenna System (DAS or i-DAS) antennas are low profile and designed to be mounted discreetly to a hard or tiled ceiling. Used in a series throughout large buildings, campus areas or even in below ground sections of a building the antennas can provide a distributed LTE or Wi-Fi signal to where it is required most. With a growing demand for in-building connectivity and higher data rates, larger smart or connected buildings require a series of antennas in order to distribute signal around the building or campus area.

Rectangular Horn Antennas
-
SAGE Millimeter wave rectangular gain horns, also called pyramidal gain horns, are offered as both standard and custom models with a rectangular waveguide interface. The pyramidal gain horns only support linear polarization. With a calibrated gain chart, these horns can be used to measure the gain of other antennas by comparing the generated signal levels of both. For this reason, these horns are also referred to as standard gain horns. The listed models offer 23 dB nominal gain, 10/11 degrees typical half power beamwidth and 14 dB/30 dB typical side lobe levels at the center frequency of the band. These horns cover full waveguide bandwidths within the frequency range of 8.2 to 170 GHz. In addition to the models listed below, models with 10, 15, 20 and 25 dB gain and other frequency bands are also available.

The standard models operate across the full waveguide band and offer 17 dBi nominal gain, 25 degrees half power beamwidth and a -28 dB side lobe level at center frequency. The below standard offering covers the frequency range of 8.5 to 140 GHz. However, other frequencies or gain values are also available.
