Abstract :
MATLAB programs based on Geometrical Optics (GO) theory were used to calculate the standard uncertainty introduced by the ripple of Anechoic Chamber (AC) in OTA (Over The Air) test. The same method was also used to study the influence of various factors, including high directivity measurement antennas and high performance absorbers. In addition, we likewise found that support structures should be carefully designed to reduce their negative influence on OTA Test ripple quality.
