摘要
从泄漏同轴电缆和天线的辐射理论出发,利用射线追踪法,以屏蔽良好的室内空间为例分析了其中由泄漏同轴电缆和单极天线产生的辐射场.通过比较,体现出了泄漏同轴电缆的场强在这种特定环境下具有分布均匀的优越性.该理论和结果可以扩展到其他场所,对于进一步研究闭域空间中的无线通信问题具有较强的参考价值.
Beginning with the radiation theory of leaky coaxial cable and antenna and using the ray tracing method, the radiated fields produced by both leaky coaxial cable and monopole antenna were analysed with the well shielded indoor space as example, By comparison, leaky coaxial cable showed advantages in the coverage of the radiated field in such special area-the radiated field with more uniform distribution, The theories and results can be extended to other blind zones and have reference values in further research on solving the problems of communication in the blind zone.
