Antenna test ranges

Antenna test chambers can be used to perform near field and far field measurements. Large microwave chambers (ranges) are built to test radar systems (RCS), Aerospace equipment (such as satellites) and a wide range of antennas and antenna applications. Validation of the RF characteristics in the quiet zone (QZ) of an antenna test range is done using the Free Space VSWR test procedure.

Typical specifications for an antenna test chamber:
Shielding construction*  2mm ZMA-140 galvanized shielding panels incl. structural steel support
Absorbers MTseries polystyrene microwave absorbers
(type depending on chamber performance criteria)
Ventilation Honeycomb panels
Personnel door RF shielded swing door model 1766-0921 (900x2100mm)
AUT door RF shielded sliding door (dimensions depending of the size of AUT)
Wall panel 3mm galvanized steel with sufficient RF connectors
Power line filters High performance shielded mains power line filters
Lighting CDMT lights
Floor system Wooden floor incl. floor absorbers and walkway absorber solution
(distributed load depending on weight of the EUT)

* Comtest can design all antenna test chambers based on a RF shielded or framed chamber solution
