在100ghz以上，传统的反射式小型天线测试范围（CATR）的应用变得越来越困难。主要问题是对反射镜的表面精度要求严格，因此制造成本高。这些问题可以通过使用全息图类型的紧凑范围来克服，其中平面全息图结构被用作准直元件。通过理论分析和119ghz的测量，对该方法的性能进行了研究。
The application of conventional reflector-type-compact antenna test ranges (CATR's) 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.
