Gain Degradation of KVN 21-m Shaped Cassegrain Antenna due to Misalignment of Antenna Optics
In this paper, gain loss of KVN (Korean VLBI Network) 21-m shaped Cassegrain antenna due to misalignment of antenna optics is calculated using ray-tracing method. It enables us to estimate alignment tolerances of feed and sub-reflector positioning. According to numerical results, KVN 21-m shaped Cas...
