[Institution of Engineering and Technology 12th European Conference on Antennas and Propagation (EuCAP 2018) - London, UK (9-13 April 2018)] 12th European Conference on Antennas and Propagation (EuCAP 2018) - Research Advances in Phased Array Antennas for Satellite Communications
摘要： Recent research advances in phased array antennas for mobile satellite communications in the State Key Laboratory of Millimeter Waves (SKLMMW) are reviewed, including the Ku-band multiple-panel phased array antenna with almost half sphere coverage, the Ka-band low cost linear phased array module for planar array applications, a single board dual polarized S-band phased array for China S-band mobile satellite communications. The development for fast phased array calibration and measurement is also introduced.

PLANAR PHASED ARRAY CALIBRATION BASED ON NEAR-FIELD MEASUREMENT SYSTEM
摘要： Matrix method for phased array calibration is an excitation reconstruction method by solving the linear equations based on the linear relationship between the measured near-field data and element excitations. In this paper, we propose a modified matrix method, in which the phased array model is simplified, to measure the element excitations of planar phased array. Our method reduces measurement time greatly at the cost of introducing some calibration errors. The introduced calibration errors can be minimized with the array excitation strategy proposed in this paper. Experimental results validate the effectiveness of our methods in calibrating planar phased arrays.
