| 摘 要： | 为了对被测天线进行快速？定量的动态测量,获得天线频带特性的实时测量结果,可以采用多通道扫频近场测量方法。本文提出了一种采用85301B天线自动测量系统,使用HP85330A作为系统控制器的多通道扫频近场测量方法。在一定的频段内进行点频和扫频测试,将点频和扫频近场数据变换成远场方向图,并对各频点的数据进行比较分析。最后分析了误差产生原因并给出了一种修正方法。测试数据表明与传统的点测法相比,有效地降低了测量时间,提高了测量系统的测试效率。

| Abstract: | In order to measure antenna with rapid,quantitative dynamic measurement and obtain real-time measurement results of frequency bandwidth characteristics,a technique of multi-channel and sweep frequency near-field antenna measurement is used.An automatic antenna measurement system of 85301B,in which HP85330A is used as system controller, is presented in the paper. In a certain band the antennas with sweep frequency and point frequency measurement are carried out and the data at every frequency point by transf... |
