| 摘 要： | 本文介绍了一种带有非线性器件的射频通道天线的测试方法,针对这一种类型的天线系统,构建了一种收发不同频的天线测试系统。基于已有的室内天线远场测试系统,在不改变原有远场系统硬件配置以及软件系统的基础上,只添加一套对应的混频装置,就可完成对带有发射上变频与接收下变频通道的天线测量。系统的改造方案具有一定的通用性。在工程上对内置频率转换器件的这一类型天线方向图的精确测量具有一定的借鉴意义。

| Abstract: | This paper presents a method of measurement for the antenna with the RF channels ot nonlinear components and proposes an antenna：measurement system with different transmitting and receiving frequency. Without any changes of configuration of hardware and software, the system, based on an existing indoor antenna far field range, can carry out the measurements for the antenna transmitting with up-converter and receiving with down-converter only by an adding a set of mixer system. The update for the existing far field system is generic and enlightening on technical application for the kind of antenna pattern measurement with frequency converter components. |
