缝隙波导具有频带宽、口面效率高等特点，根据道尔夫-切比雪夫口径分布法，用MATLAB软件编程对单脊波导缝隙天线阵列辐射缝隙参数进行计算，设计了一个8缝隙单脊波导缝隙阵天线，并利用三维电磁仿真软件HFSS对天线缝隙的参数进行优化，对天线的带宽特性进行了仿真研究。结果表明，单脊缝隙波导的尺寸参数对带宽有影响，相对于矩形缝隙波导，单脊缝隙波导驻波带宽有较大幅度的展宽，研究结果可为缝隙脊波导在通信与雷达天线方面的应用提供参考。

Slot waveguide is characteristic of wide frequency band and high aperture efficiency. This paper calculates the radiation slot parameters of the singleridge waveguide slot antenna array using MATLAB software programming according to AdolfChebyshev aperture distribution method and designs an 8slot singleridge waveguide slot array antenna. Furthermore, it optimizes the gap parameters and simulates the bandwidth characteristics of the antenna using the threedimensional electromagnetic simulation software HFSS. The results indicate that the size parameters of the singleridge waveguide slot affects the bandwidth and relative to the rectangular slot waveguide, the VSWR bandwidth of the singleridge slot is substantially broadened, which provide a valuable reference for the applications of slot ridge waveguides in communications and radar antennas.
