Abstract: According to the batch testing requirements of mobile communication antennas, the spherical scanning near-field antenna measurements technology is investigated. After the system is cali-brated in amplitudes and phases with all probes, the measurements method is got with many ad-vantages: more sampling probes, faster speed for antenna pattern show and higher degree of au-tomation. In order to verify this method, the ceiling antenna is tested, which shows that the method is better than the traditional far-field test, and it can be more efficient and more accurate.
