Abstract :
A brief review of antenna test methods at THz frequencies is presented. Two hologram-based compact antenna test ranges (CATR), one at 322 GHz and another at 650 GHz were designed, constructed, and used for testing the ADMIRALS RTO antenna of 1.5 m in diameter. These CATRs are based on 3-meter diameter computer-generated amplitude holograms.
