Ka-Band standard gain horn measurement on spherical near-field scanners

The measurement of a standard gain horn SGH28 from NSI for Ka-band using two different spherical near-field test ranges will be described. The principal differences in the measurement set-up like used transmitter/receiver, probe distance, scan radius etc. will be listed and the results of the different campaigns will be discussed. There will also be a short evaluation of measurement dynamic range and its impact on the measurement results. The effects of scanning in different axis will be displayed.
