| 摘 要： | 设计了一个Ka 波段紧缩场天线。馈源设计结合角锥喇叭在反射面边缘照射电平下降快与波纹喇叭波瓣宽度宽的特点，通过给角锥喇叭加扼流套的改进设计来实现对反射面的照射。反射面采用锯齿型边缘来降低边缘的绕射作用，并进一步在无法加工锯齿部位贴附三角形吸波材料来减小绕射对静区特性的影响。暗室内采用平面测量结果表明，Ka 波段紧缩场天线静区特性满足设计指标要求。

| Abstract: | Ka band compact antenna test range (CATR) antenna is designed in the paper. The power level of pyramid horndecreases quickly at the edge of the reflector. And corrugated horn has a greater beam width. Combining these two features, feedresource is designed. Irradiation of the reflector is achieved by adding choke to pyramid horn. Serration edge is employed toreduce the edge diffraction. Moreover, for the areas where serration is impossible, triangle wave absorbing materials are attachedto reduce the influence of diffraction on quiet zone performance. The planar measurement result shows that the quiet zone featureof ka band |
