本文应用变分法结合应用Babinet原理,导出波导宽边纵缝的等效导纳公式。这些公式可用于计算缝中心距短路板为四分之一波导波长和离短路板较远两种情况的等效导纳。通过分析计算结果,说明用通用归一化导纳曲线提供阵的设计的可能性。还给出实验结果与计算结果的比较。
In this paper, the differential admittance method based on Babinet’s principle is used to derive the equivalent admittance formula of the waveguide wide-edge longitudinal seam. These equations can be used to calculate the equivalent admittance of the slit center to the quarter-wave length of the shorting plate and to the distance from the shorting plate. By analyzing the calculation results, we illustrate the possibility of using a generalized normalized admittance curve to provide the design of the array. Also given the experimental results and the results of the comparison.
