2019–2022 ESA-EurAAP Facility Comparison Campaign with the DTU-ESA mm-VAST Antenna - Reference Pattern at 19.76 GHz

The 2019–2022 ESA-EurAAP Facility Comparison Campaign with the DTU-ESA mm-VAST antenna has involved 10 European institutions and 11 spherical near-field and compact range measurement facilities. The mm-VAST antenna, specifically designed as a reference antenna, is employed in three operational configurations at 19.76 GHz, 37.80 GHz, and 48.16 GHz, including both linear and circular polarization. This work presents the final results of the campaign for the first studied configuration, at 19.76 GHz and linear polarization. The presented results comprise the measurements received during the course campaign, as well as a comparison in terms of several metrics. From these measurements, an aggregated pattern is created as a weighted average of the received measurements. This averaged pattern is considered the new reference pattern of the mm-VAST in the 19.76 GHz configuration.
