摘　　要：针对移动通信天线的批量测试的需求,本文研究了球面扫描近场天线测试技术,经过幅度和相位校准,得到了取样探头多、测量天线方向图速度快、测试自动化程度高的天线测量方法和流程,通过对吸顶天线的测试验证,说明该方法比传统远场法测试能够取得更高的效率和更高的精度。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.
