Sector Antennas
-
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.

Probe Antennas
-
Probe antennas are offered as both standard and custom models with a rectangular waveguide interface. Probe antennas can only support linear polarization. These antennas are often used to measure the gain of other antennas by comparing the signal levels of the probe antenna and antenna under testing. The standard models operate across the full waveguide band and offer 6.5 dB nominal gain and 115 and 60 degrees half power beamwidth at center frequency. The below standard offering covers the frequency range of 8.2 to 170 GHz.

Horn Antennas
-
Broadband antennas, compared to half wave dipoles, reduce test time because the technician did not have to stop the test to adjust the dipole antenna for each frequency. Most compliance standards now require the use of such antennas. The latest version of Mil-Std 461E states the used of broadband double ridge guide horn antenna as the antenna of choice for frequencies above 200 MHz.
