Horn Antenna Gain Measurement Based on Vector Network Analyzer [PDF]
利用微波暗室、矢量网络分析仪、角锥喇叭天线以及电脑等设备建立了一套喇叭天线测量系统;采用两相同天线法,分别测量了4~6 GHz、6~8 GHz角锥喇叭天线的增益值,对测量数据进行误差分析和近距修正;并将增益的实测值与理论计算值进行对比.实验结果表明,近距修正后,所测量的4~6 GHz与6~8 GHz频段天线的增益实测值与理论值的最大偏差值分别为-0.20 dB和-0.19 dB,均在±0.25 dB范围内,符合标准增益天线增益的精度要求,也与天线出厂的指标相符 ...
