摘要
本文从Floquet定理出发 ,详细分析了漏泄同轴电缆的辐射模式 ,给出了辐射模式的存在条件 ,讨论了单模辐射的频带宽度。在此基础上进一步研究了高次模的抑制方法及其在电缆结构上的实现 ,目的是扩展单模辐射的频带宽度。本文理论是根据频带宽度的要求设计漏泄同轴电缆外导体上缝隙排列方式的基础。
Starting from the Floquet theorem,the radiation mode of the Leaky Coaxial Cable is analyzed in this paper,the existing condition of the radiation mode is given,and the frequency bandwidth of the mono mode radiation is discussed Then,the restraint method of the high order mode is studied for extending the mono mode radiation bandwidth,and the means how to realized it to the configuration of the leaky coaxial cable are discussed The theory of this paper is the basis of the design of the slot array configuration of the leaky coaxial cable when the requested frequency bandwidth is given
