摘要: 通过建立理论模型研究了波导窄边缝隙天线中缝隙随着波导宽边尺寸调节过程中其谐振电导的变化规律,包括缝隙的宽度、缝隙切入宽边的深度、波导壁厚等对谐振电导及谐振长度的影响。得到了较为准确的拟合公式,利用该公式计算得到的缝隙参数能够满足工程设计的需要。此外,还分析了缝隙辐射电场随波导宽边调节的变化情况。Abstract: The resonant conductance of the slot is variable with the changing of the broad wall dimension of the waveguide. In this paper, the variable rule of the resonant conductance of the slot in a wide side dimension adjustable slot-waveguide is studied, as well as the influence of the slot width, the cutting depth, and the duct thickness. Fitting equations are obtained by suitable theoretical model, and they can satisfy the requirement of engineering design. Besides, electric field radiation of waveguide slots varying with the dimension adjusting of the wide side wall is analyzed.
