Toroidal CATR for Applications in 5G and LEO Satellites

As 5G technology and Low Earth Orbit (LEO) satellites revolutionize the wireless communication landscape, the need for accurate and comprehensive OTA (Over-The-Air) testing becomes critical. In this paper, we introduce a brand new OTA measurement system, toroidal compact antenna test range (TCATR) specifically tailored to address the unique challenges posed by 5G and LEO satellite communications. The system encompasses a wide frequency range, adaptive plane waves moving capabilities to emulate the moving LEO satellites or 5G moving subscribers, to ensure precise testing of ground phased array system and 5G moving subscribers. In this paper five plane waves are generated with the symmetrical torus as the main reflector, and five sources are located inside another anechoic chamber.
