摘要： 远场测量是获得天线辐射特性的一种常用方法。然而对于一维电尺寸大，另一维电尺寸小的天线，如基站天线，由于场地因素的限制，往往不能满足远场测量条件，用近场测量又费时费力。在这种准远场条件下，天线测量结果与远场情况下的测量结果有较大差异。本文基于柱面波展开，给出了一种由准远场距离上测得的方向图计算远场的理论计算方法，经过该算法补偿后的结果与理论计算结果吻合很好，从而验证了算法的正确性。

Abstract: Far-field antenna measurement is a common method to obtain antenna radiation characteristics.However,for the antenna with large one dimension and small one dimension,such as the base station antenna,it is often unable to meet the far-field test conditions due to the limitation of site factors,and the near-field measurement is time-consuming and laborious.In this Quasi-far-field condition,the antenna test results are quite different from those in the far-field condition.This paper presents a theoretical calculation method for calculating the far-field pattern from the pattern measured on the distance of the Quasi-far field based on cylindrical wave expansion.The results of the algorithm are in good agreement with the results of the theoretical calculation,and the correctness of the algorithm is verified.

Key words: Antenna test, Base station antenna, Quasi-far field, Correction algorithm
