In this paper, an approximate expression was presented to compute the load impedance base on the theory of transmission line, and the numerical approximation method was employed to obtain the normalized admittance of the waveguide slot in array.
利用传输线理论构造负载阻抗的近似计算公式,采用数值逼近法直接计算阵列中的缝隙归一化导纳,从而可以在Elliott波导缝隙天线阵设计过程中避免使用感应电动势法和矩量法,进而可以提高设计速度。
