摘　　要：对平面近场扫描截断误差的上限表达式进行了讨论，同时对几种不同类型天线的近场测量数据进行了二维截断误差的计算机模拟．这些结果与美国国家标准技术研究所进行的一维模拟相比较，更为精确．它为定量分析该项误差对天线电性能指标的影响提供了有实用价值的依据．This paper discusses the upper bound of the truncation error for planar near field scanning. A computer simulation of truncation error by using the data measured is made. The results obtained are more accurate and reliable, compared with the one dimensional simulation results provided by the US National Institute of Standard and Technology. As a result, the practical basis for quantitatively analyzing the effect of the error on antenna electrical performance indices has been provided.
