摘要

我们研究了使用PVC管壁作为通信路径的MIMO通信。我们将两根天线分别连接在1米长的PVC管的两个端面上，并对其传输特性进行了评估。当天线安装在PVC管截面上时，5 GHz时的S21约为−25 dB，比天线安装在管内和自由空间时的S21高15 dB以上。MIMO信道容量最大(0.98 bit/s/Hz)时，天线位于管道对角线两端的相同位置。

Study on MIMO Communication using Microwave Guided-Modes Propagating along PVC Pipe Wall

We investigated MIMO communication using a PVC pipe wall as a communication path. We attached two antennas to both end faces of 1-m-long PVC pipe, and evaluated its transmission characteristics. When the antenna was installed on the cross section of the PVC pipe, S21 at 5 GHz was about −25 dB, which was more than 15 dB higher than that in case antennas are set inside the pipe and in free space. MIMO channel capacity becomes maximum (0.98 bit/s/Hz) when the antennas were placed at the same positions at both end faces on the diagonal line of the pipe.
