摘　　要：本文分析了扇面波导中主模场分量的精确解与近似解，假定波导中仅传输主模的条件下，利用等效原理导出了扇面波导曲宽面上纵向并联缝隙的谐振电导公式，给出计算例子，用于设计缝隙线阵天线获得较满意的结果．In this paper,the rigorous and approximate solution of the field components for the dominant mode in a sectorial waveguide are investigated. Assuming only dominant mode to be propagated,the formula of the resonant conductance for longitudinal shunt slots cut in the curved broad face of the waveguide is derived by using equivalence principle.The example is presented and the result obtained is quite satisfactory,when the formula is used to design linear slot array.
