摘　　要：解决车载天线装车问题需要天馈系统小型化设计。采用高性能环焦天线配合小尺寸宽带波纹喇叭轴向紧凑设计、TE21模跟踪器小型化技术以及超短宽带90°极化器综合设计方法，研制了具有“C频段4／6GHz收／发双圆／双线”功能的小型化天馈系统，实测指标良好。In order to solve the problem of loading vehicle antenna, miniaturization design of antenna and feeder system is needed. Using the high performance ring focus antenna with small size wideband corrugated horn axial compact design, and TE2~ mode tracker miniaturization and ultra broadband 90° polarizer synthesis design method, a miniaturized antenna system with function of C band 4/6 GHz dual circular/dual linear polarization is developed, and the performance indicators are very good.
