摘　　要：研究的毫米波段斜扇形波束裂缝阵天线是一种薄形的波导裂缝阵 ,结构新颖 ,特别适用于飞行器天线。由于这种天线的数学模型比较复杂 ,并且工作在毫米波波段 ,使设计和分析带来了一定的困难。根据裂缝阵设计的理论基础 ,对毫米波段斜扇形波束裂缝阵天线进行了研究 ,采用了终端短路的准行波天线阵的方案 ,设计得到的毫米波裂缝阵天线具有斜角扇形波束、较低副瓣、宽频带和薄形等优点。理论结果和实测结果相吻合 ,在工程上应用已得到了良好效果。The new kind of millimeter wave quasi traveling antenna array was investigated. The antenna was a thin type of slot array of wave guide. The structure of the wave guide’s terminal short was applied. Because the mathematics model of the antenna was more complicated and the antenna worked in the millimeter wave band, it was very difficult to design.Based on the theory of the slot array design, the main difficult points have been solved. The antenna designed has advantage with the beam of inclined angle, low side lobe level and wide work band (more than 1.4GHz). The theoretical results and experimental ones are in good agreement. It befits especially to apply in the field of aero apparatus. The favorable effects have been gotten in the application of the engineering project.
