摘　　要：文中提出了改进的Friis传输公式,据此得到天线增益远场测试5种方法的工程处理公式。分析指出,其中"比较法,,测量天线增益不需要考虑测试馈线的插入损耗和提供收、发天线的间距,便于工程应用。最后,以3种方法计算5种规格角锥喇叭增益的理论曲线,给出了标准增益喇叭正确设计和精确标定的建议。The modified Friis transmission formula is put forward in this paper. Based on this, the engineering processing formulas on antenna gain 5 far field test methods are obtained. This analysis points out that, antenna gain test by＂ the comparative law＂ is no use for think about insertion loss of test cables and calculating distance between transmitting antenna and receiving antenna, thus it is conveniently for apply to engineering. At last the gain theory curves of different 5 pyramidal horns are calculated with 3 methods and advice on standard-gain horn correct design and exact calibration is given.
