摘　　要：通过对小面阵天线的设计、仿真及实际测量，提取了互耦情况下的特定角度的有源谐振导纳和缝深。采用拟合方法得到了天线每个缝隙的倾角和缝深，并用相邻波导缝隙反相来抑制交叉极化。上述措施使窄边波导裂缝天线获得了良好的交叉极化和低副瓣性能。The design of slots in the narrow wall of waveguide antenna is presented in this paper. The active harmonic admittance and the slot depth with mutual coupling are gained by the simulation and measurement of small arrays. The obliquity and the cutting depth of each slot are obtained by fitting method. The cross polarization is suppressed by reversing the adjacent waveguide slot phase. Through the above measures, the better cross polarization and low side lobe performance of the edge-slotted waveguide antenna are achieved.
