摘要
利用矩量法对矩形波导宽边纵缝阵列天线进行了理论分析和计算。首先利用缝隙口面切向磁场连续的条件建立关于未知电场的联立积分方程,考虑了所有的互耦、高次模及波导壁厚的影响,然后对两个实际阵列进行了编程计算,计算结果与文献和HFSS软件的仿真结果吻合良好,仿真过程中对矩形缝和半圆头缝进行了转换。
Theory analysis and calculation of the rectangular waveguide longitudinal slot arrays are made by using moment method.Firstly,the integral equations about unknown electric field are derived on the continuity of the tangential magnetic field on the slot,including the inner and outer mutual couplings,the effect of the finite waveguide wall thickness and the internal higher order mode coupling.Then two arrays are computed,the obtained results are in good agreement with the emulational results.The transformation is made between rectangular slots and rounded slots.
