摘要

本文研究了一种地埋管道检测机器人，利用沿聚氯乙烯(PVC)管壁传播的微波引导模式改善5 ghz频段多输入多输出(MIMO)通信的信道容量。我们设计了一种平面Yagi-Uda天线，以减少以PVC管壁为传播路径的通信中的传输损耗。通过在Yagi-Uda天线上附加与PVC管内壁曲率相同的PVC适配器，消除天线与PVC管内壁之间的间隙，提高了天线与PVC管之间的耦合效率。与偶极子天线相比，使用带PVC适配器的平面Yagi-Uda天线可将沿1m长直PVC管壁传播的5ghz波段微波信号的传输损耗降低7db。使用平面Yagi-Uda天线的2 × 2 MIMO系统的信道容量是使用偶极子天线系统的两倍以上。

Improvement of Channel Capacity of MIMO Communication Using Yagi-Uda Planar Antennas with a Propagation Path through a PVC Pipe Wall

This study investigates the improvement of the channel capacity of 5-GHz-band multiple-input multiple-output (MIMO) communication using microwave-guided modes propagating along a polyvinyl chloride (PVC) pipe wall for a buried pipe inspection robot. We design a planar Yagi-Uda antenna to reduce transmission losses in communication with PVC pipe walls as propagation paths. Coupling efficiency between the antenna and a PVC pipe is improved by attaching a PVC adapter with the same curvature as the PVC pipe's inner wall to the Yagi-Uda antenna to eliminate any gap between the antenna and the inner wall of the PVC pipe. The use of a planar Yagi-Uda antenna with a PVC adaptor decreases the transmission loss of a 5-GHz-band microwave signal propagating along a 1-m-lomg straight PVC pipe wall by 7 dB compared to a dipole antenna. The channel capacity of a 2 × 2 MIMO system using planar Yagi-Uda antennas is more than twice that of the system using dipole antennas.
