Kaelus Antenna Test Chamber

This is a 360 video of The compact, far-field test range for antennas located at the Kaelus Design Center in Täby, Sweden. The Compact range is built in a 21x12x10.5 meters anechoic chamber and is designed for wide frequency measurements (0.6-40 GHz). The range is feed-horn equipped from 0.5 to 6 GHz. It consists of a serrated parabolic reflector with a total size of 7.5 x 7.5 m. The focal length is 11.6 m and the quiet zone is a cylinder with height and diameter of 3 m. The reflector is fed by a set of circular horns. The field is collimated by the reflector so that a nearly plane wave is incident on the quiet zone located 13.75 m from the reflector. In the quiet zone, there is a turntable (AL4575) and a Roll-AUT (AL360), which allows for measurement of any cut in an antenna pattern, as well as convenient change from elevation to azimuth patterns.
