A Technique to Evaluate the Impact of Flex Cable Phase Instability on mm-Wave Planar Near-field Measurement Accuracies

Author: Daniël Janse van Rensburg

The impact of flex cables on mmwave planar near-field measurements is considered. It is demonstrated how to estimate measurement errors due to these effects and an example is presented. The techniques shown here allows one to evaluate existing antenna test facilities to assess their suitability for mm-wave testing and also shows that flex cables provide very accurate results despite their imperfections.
