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 for antenna measurement can result in a high-performance test zone and optimized test results.
Over 30 years of engineering know-how goes into the design and manufacturing of compact range systems from MVG-Orbit/FR. This expertise carries through from the project analysis phase to implementation and installation. Precision, accuracy, and state-of-the-art techniques are in every piece of equipment we build, with proven results in the numerous systems continuously in use today.
