摘　　要：从泄漏同轴电缆的辐射理论出发,以屏蔽良好的室内空间为例分析了其中的辐射场,再根据耦合损耗的定义,利用接收功率和电缆传输功率得出了漏缆的耦合损耗,同时讨论了室内墙壁的材质对耦合损耗的影响,并通过仿真对结果进行了验证.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.Starting with the radiation theory of leaky coaxial cable, the radiation field of indoor space with good shield is analysed. Then according to the definition formula of coupling loss, the coupling loss of leaky coaxial cable is obtained from received power and transmission power of the cable. Meanwhile, the effect of the material in the room wall on the coupling loss is discussed. The numerical simulation is conducted to prove the analysis result. The theories and results in the paper can be extended to other blind zones and provide reference values in further researches of such problems related to communication in the blind zone.
