Abstract :
A hologram can be used as a collimating element in a compact antenna test range (CATR) at millimetre and sub-millimetre wavelengths. The performance of the CATR can be improved by using modified illumination of the hologram with a dual reflector feed system (DRFS). A 650 GHz dual reflector feed system (DRFS) was designed as part of an ESA project aiming at the measurement of a 1.5 m antenna at 650 GHz during 2006. In this paper, the design of the 650 GHz DRFS is presented and the simulated DRFS beam is compared to the desired hologram illumination.
