Antenna testing at 322 GHz in a hologram CATR

We tested the ADMIRALS representative test object (RTO) at 322 GHz in a hologram based compact antenna test range (CATR) during the summer 2003. The RTO is used for demonstration of the current satellite antenna technology and for comparison of potential antenna testing methods at mm- and suh-mm wavelengths. This paper describes the development work of the hologram CATR and tbe testing of the RTO. Test results of the quietzone and measured cut of the radiation pattern of the RTO are presented.
