Measurements And Simulations Correlation Of High Reliability Reflector Antenna

In antenna measurements, test procedures and best practices, validated by comparative measurements, constitute widely adopted tools to determine the uncertainty and thus the achieved accuracy of a given antenna measurement. For numerical simulations, there are no equivalent standards or tools to determine the accuracy of the numerical modelling of the same antenna.A highly stable reference antenna of which the mechanical deviations from the intended design has been minimized through careful manufacturing, has been identified as part of a EurAAP facility comparison campaign. The antenna has been measured in different facilities and simulated by different software vendors using different numerical methods. A comparison of simulations and measurements of this antenna at 10.7GHz and 18GIlz has been reported in 11-21.In this paper, we report our findings on the correlation between measurement and simulation at 30GHz and 38GHz. The investigation comprises additional measurements ranges and software vendors,
