CATR for microwave testing purposes
Compact antenna test ranges (CATR) provide a convenient means of testing antennas and wireless communication equipment in locations where obtaining far-field spacing would normally be too difficult. A compact range allows for less space to be used, but requires a second source antenna and a secondary reflector that work together to generate a region of plane waves. This is the quiet zone where testing can take place. Comtest builds high-performance CATR facilities that can measure medium to large size antennas over a range of 1 to 110 GHz.

Compact antenna test ranges – primary applications
Most of the equipment being tested in CATR facilities falls under the category of mobile & telecom products, antenna arrays and other electronic products that use wireless communication techniques. A CATR’s primary purpose is measuring the radiation and scattering characteristics of high performance antennas over a wide range of frequencies.
Comtest Engineering standard
Our compact antenna test ranges are constructed using high-end materials and the latest techniques. Because high RF shielding effectiveness is often a requirement for a microwave anechoic chamber, an RF shielded room is used in addition to a fully lined treatment on floor, walls and ceiling with our high performance polystyrene microwave absorbers. These are some of the components used:
- 2mm ZMA-140 galvanized shielding panels
- Structural steel support depending on range size
- RF shielded swing door model (dimensions depending on the size of the AUT)
- MT series polystyrene microwave absorbers (type depending on chamber performance criteria)
