Abstract :
The application of conventional reflector-type compact antenna test ranges (CATRs) becomes increasingly difficult above 100 GHz. The main problems are the tight surface accuracy requirements for the reflectors and, therefore, the high manufacturing costs. These problems can be overcome by the use of a hologram type of compact range in which a planar hologram structure is used as a collimating element. This idea is described and its performance is studied with theoretical analyses and measurements at 119 GHz
