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.

Antenna Research Associates
Vehicular and Handheld antennas are available for communication, surveillance, signal DF, network repeaters and RF Jamming applications. A single omni or high gain directional ARA antenna may cover all cellular and/or Tetra communication bands and are compatible with all network technologies (GSM, CDMA, etc.). These wideband antennas replace the need for several single band antennas and are ideal for vehicular installations as well as handheld radio mounted applications. Permanent installations, quick deploy magnetic mounts or convenient pistol grips for radio location are available.

KRYTAR, Inc.
KRYTAR’s directional couplers are uniquely designed for systems applications where external leveling, precise monitoring, signal mixing or swept transmission and reflection measurements are required. These couplers provide simple solutions for many applications including electronic warfare (EW), commercial wireless, SATCOM, radar, signal monitoring and measurement, antenna beam forming, and EMC testing environments. For many space-restricted applications the compact size makes KRYTAR directional couplers ideal solutions.

A sector antenna is a type of directional microwave antenna with a sector-shaped radiation pattern. The word "sector" is used in the geometric sense; some portion of the circumference of a circle measured in degrees of arc. 60°, 90° and 120° designs are typical, often with a few degrees 'extra' to ensure overlap and mounted in multiples when wider or full-circle coverage is required (see photos below). The largest use of these antennas is as antennas for cell phone base-station sites. They are also used for other types of mobile communications, for example in Wi-Fi networks. They are used for limited-range distances of around 4 to 5 km.

ALP690 -
Lectrosonics, Inc.
The ALP690 is a high-performance LPDA (log periodic dipole array) antenna with a bypassable, built-in RF amplifier for use with wireless microphone receivers in location or studio production. The design delivers +4 dBd of passive gain in a directional pattern to extend operating range, and, when DC power is applied, the amplifier applies gain to overcome loss in long coaxial cable runs. By offering both active and passive operation modes, the ALP690 can be used as a receiver antenna (active or passive) and as a transmitter antenna (passive only).

Schwarzbeck Mess Elektronik
The broadband horn antennas BBHA 9120 offer a very low SWR in their nominal frequency range and a very broad bandwidth. The gain increases with frequency up to approx. 21 dBi, depending on the horn's size and shape. The increasing gain with frequency helps to compensate cable losses. The BBHA 9120 series is suitable for both, transmission and receiving applications. The max. allowed Input Power is only limited by the female N-connector. The detailed manual of the calibrated test antennas includes Gain, Antenna Factor, SWR and Directional Patterns. The antenna is mounted with the 22 mm tube, equipped with a Index Ring for quick changes of polarisation without using tools.

ZTS Technologies Co., Ltd
Fixed Terminations absorb RF & microwave energy and are commonly used as dummy loads of antenna and transmitter.They are also used as match ports in many multi-port microwave device such as circulator and directional coupler to make these ports which are not involved in the measurement be terminated in their characteristic impedance in order to ensure an accurate measurement
