摘　　要：在天线的辐射特性和目标散射特性的测试中,为了使紧缩场具有更好的静区特性,通过优化反射面卷边曲面和边缘赋形轮廓设计,降低了反射面边缘的绕射场强度和进入紧缩场静区的绕射场能量;应用此设计方法,建造了用于20~50 GHz低成本小型紧缩场实验室,与平面近场直接测试结果进行对比分析.测试结果表明,本文方法设计的卷边反射天线具有较好的静区特性,被测天线方向图测试结果与平面近场结果基本一致.In order to make the compact antenna test range(CATR)obtain better quiet zone characteristics in the measurement of antenna radiation characteristics and target scattering characteristics,by optimizing the rolled-edge curved surface and the edge contour design,this paper realizes the reduction of the diffraction field in-tensity at the edge of the reflection surface and the diffraction field energy entering the quiet zone of the CATR,then uses this designing method to build a small CATR laboratory with low cost for 20-50 GHz,and finally makes a comparison with the plane near-field direct test results.The results show that the rolled-edge reflector antenna designed by the method in this paper has good quiet zone characteristics,and that the test result of the measured antenna pattern is basically consistent with that of the plane near field.
