In this paper, the calibration path implementation of the Ku band tracking antenna system with about 2000 arrangements and the verification method of the calibration function during the near field test were described. The calibration path of the tracking antenna system is an internal loop consisting of an antenna element assembly, a TR assembly, an RF power combiner assembly, a driving amplifier module, and an RF cable. The gain and phase change for each channel for calibration are performed by the 4CH Beamformer IC inside the TR assembly. After extracting the align data and calibration data, during the near field test process, the change in the antenna system state was imitated by changing the RF cable inside the antenna system. The CLUT(Calibration Look Up Table) was calculated by re-extracting the antenna system calibration data after the state change and calculating the difference from the antenna system calibration data before the state change. Thereafter, by applying the alignment LUT(Look Up Table) loaded into the antenna system before the state change and the CLUT through the scenario of the RF test equipment, it was verified whether the antenna system maintains the alignment state, the calibration function, and the effectiveness of the calibration value when the state of the antenna system changes.
