The translated spherical wave expansion is an advanced near field to far field transformation technique which allows to efficiently deal with spherical near field measurement of offset mounted antennas. While in the past this technique has been extensively validated considering low/medium directive antennas mounted on complex structures like vehicles, it hasn’t yet been applied to electrically large antennas. In this paper, spherical near field measurements of a 30dBi reflector antenna measured in different offset configurations will be presented. The effectiveness of the translated wave expansion will be validated considering up to more than 4-time down-sampling with respect to the conventional requirements.
