泄漏同轴电缆单模辐射频带扩展技术的研究

Research on the expansion technology of the single-moderadiation frequency band of leaky coaxial cable

运用F loquet定理对泄漏同轴电缆辐射模式进行了分析,得出了单模辐射产生的条件,然后研究了高次模辐射的抑制,分别讨论了对垂直开槽和倾斜开槽的泄漏同轴电缆实现单模辐射频带扩展的具体方法,为泄漏同轴电缆在宽带通信中应用提供了理论基础.

By analyzing the modes of the radiation of leaky coaxial cable using Floquet Theorem, the condition of the single-mode radiation is obtained. Then, the restraint of high-order mode radiation is examined, and the particular methods to realize the frequency expansion of the single-mode radiation of leaky coaxial cable with vertical and inclined slots are discussed respectively. These methods provide a basis for the application of leaky coaxial cable to the broadband communication.
