摘要

Development work of a 119 GHz compact antenna test range (CATR), based on a 2.4 m/spl times/2.0 m hologram and its application on the Odin telescope tests are described. The hologram element comprises seven parts, which are fabricated using silk-screen printing techniques. Comparison between the theoretical and the measured quiet-zone fields of the hologram CATR is made, which demonstrates the cor...
