An important activity within the past Antenna Centre of Excellence (ACE) network was dedicated to facility comparison campaigns as reported in. The activities spanned the frequency range from L-Ka band using different antennas (VAST12, SATIMO SH800 and SATIMO SH2000). The vast amount of data from different measurements institutions within Europe and US has been used to establish a reference pattern for each of the high accuracy reference antennas. The reference patterns and the data from the facility comparison activities are considered important instruments to verify the measurements accuracies for antenna measurement ranges as well as to investigate and evaluate possible improvements in measurement set-ups and procedures. This paper gives an overview of the ongoing activities in the frame of the EURAPP working group on antennas measurements and the first considerations on useful criteria for comparing and evaluating large amount of measured antenna data.
