摘要

为了考察泄漏同轴电缆在矩形隧道中的辐射特性

根据泄漏同轴电缆的辐射理论

用时域有限差分方法计算了泄漏同轴电缆开槽口处的电磁场分布

再用射线追踪法分析了在矩形隧道中从泄漏同轴电缆槽口处漏泄出的电波经直射、反射之后所形成的辐射场

结果表明:泄漏同轴电缆辐射出的电磁波可以布满隧道空间

能够弥补传统天线在闭域或半闭域空间中存在通信盲区的缺点

从而保证了这些区域中通信的质量。

Abstract

Based on the radiation theory of leaky coaxial cable

the electromagnetic field distribution of the slots of leaky coaxial cable is calculated by using finite difference time domain（FDTD） method

and then the radiation field of electromagnetic wave in the tunnel which is transmitted by leaky coaxial cable is analyzed.The results show that the leaky coaxial cable can cover the shortages of traditional antennas in blind or semi-blind zone

and the unblocked communication inside the tunnel can be realized easily.
