ESA’s Compact Antenna Test Range at ESTEC has been relocated which has given the chance to improve the alignment of the reflectors. Based on measurements of the reflector surfaces the best-fit...

A compact antenna test range has been analysed for stray signals. The analysis is based on GTD ray tracing, i.e. obeying the reflection law in the chamber walls and assuming straight edges of...
Serrations are often applied at the edges of compact range reflectors in order to reduce the scattering from the edges into the quiet zone. At low frequencies the serrations show different...
Two ways of modelling a compact range design are presented, and the coupling to a given antenna under test (AUT) is determined and compared to the AUT far field.
The compact range models...
Compact ranges based on reflector technology may be based on different designs: single offset reflec- tor, dual offset reflector compensated for cross polarisation or an offset dual reflector...
Microwave antenna measurements seek to determine the response of an Antenna Under Test (AUT), when it is illuminated by a uniform Plane Wave. The requirement of a uniform Plane Wave illumination...
Modelling of the field in the quiet zone (QZ) of a compact range is a difficult task since the edges of the range reflectors are designed not to radiate into the quiet zone. As a consequence the...
