摘　　要：使用时域有限差分法 (FDTD法 )对矩形波导上单个辐射缝隙的特性进行了严格分析 ,得出在不同缝隙偏置、缝隙宽度和波导壁厚条件下缝隙的谐振长度、散射参数以及等效归一化导纳等特性 ,并对‘谐振状态’的定义做了讨论 。A rigorous analysis of a single radiating slot on the broad face of rectangular waveguide using FDTD method is presented in this paper. Many characteristics including the resonant length, scattering parameters and equivalent normalized admittance are obtained for different slot offsets, slot width and wall thickness of waveguide. The definition of resonance is also discussed, and all results of this paper could be a reference for the design of high performance slot array.
