Antenna Measurement Compact Range - Data Sheet

Antenna measurements in the far-field require that the antenna under test (AUT) be illuminated by a uniform plane wave. To achieve this uniform plane wave illumination, a very large distance between the antenna and the measurement source antenna is usually required. A compact antenna test range creates a plane wave field at distances considerably shorter than those needed under conventional far-field criteria. This shorter distance allows a compact range to be conveniently located near test or integration facilities and by placing it in a shielded anechoic chamber, interferences from external sources can be eliminated. The enclosed system is equally protected from weather conditions, and confidential information is better secured. Careful analysis of requirements and implementation of the appropriate compact range system within an efficiently sized anechoic chamber can result in a high performance test zone and optimized test results.
