水下管道环境中的无线数据通信的天线设计

The Antenna Design of Wireless Data Communication in Underwater Pipeline Environment

采用小尺寸低功耗的射频芯片结合实际环境设计出螺旋结构天线,选择合适的频率,天线在轴向方向得到最大的辐射能量。使移动无线数据提取单元机和井下固定监控和无线收发一体的单元之间能够在数千米油田井下相距1.5 m的距离内实现短距离无线通信。

A helix antenna was presented together with low power RF amplifier, as the frequency fitted, the axial direction can obtain largest radio energy, So the mobile unit hanging from the ground and the permanent unit down-hole can commnunicate with each other within 1.5 meters in the pipeline several thousand meters below.
