Computer-generated holograms can be used as collimating elements in compact antenna test ranges (CATR5). Recently, a 1.5 m parabolic antenna, the ADMIRALS representative test object (RTO), was tested at 322 GHz using a hologram-based CATR that was built specifically for these tests. The construction of the compact range is discussed in this paper. A 3 m hologram was used to realize a 1.8 m diameter quiet zone. The measured quiet-zone field amplitude and phase and the measured H-plane radiation pattern cut of the representative test object are presented. The measured -3 dB beam width of the antenna was 0.0500 in the H plane. [ABSTRACT FROM AUTHOR] |
