Antenna characterization
The objective of an antenna test range is to simulate the operational environment of the test antenna so the radiation specifications would be measured in a way as realistic as possible. The distance R between the antenna under test and the transmit antenna is great enough to approximate the spherical wave by a plane wave. The conventional far-field condition must respect this relation R = 2D2/λ with D the maximum aperture diameter and λ the wavelength

Feasible measurement:Matching impedance (|S11|) Radiation pattern (0.5°) Polarization radiation pattern Realized gain (± 0.5 dB accuracy) Directivity (accuracy of gain) |
Compact Antenna Test Range (PLATINOM/CISTEME)
CATR provides a far-field condition at a relatively short distance from the feed. The principle is to produce a quasi-plane wave test region by collimating the field from a point source using a equiphase radiating aperture such as a parabolic reflector.
