摘　　要：由于传统电场探头在某些环境下进行混响室校准具有局限性,提出使用天线进行混响室场均匀性校准的方法。对两种方法进行了论述,并进行了实地测试,数据处理后分别得到同一混响室条件下两种方法所得场均匀性标准差,经过相关系数运算,可得出两种方法具有较好的一致性的结论。There are some limits in especial conditions by using E-field probes for reverberation chamber calibration. A field uniformity calibration method for reverberation chamber is advanced by using antennas, and the differences between two methods are discussed as well. After calculation of standard deviation and correlation coefficient of two methods in the same chamber, the conclusion that they all behave well in coincidence is discovered.
