摘　　要：本文设计了1种双圆极化、宽频带单脉冲馈源,采用六棱排列的单极对数周期天线阵形式,在6个倍频程内获得了一致的方向图和良好的交叉极化隔离度。通过对比例因子t的分析及辐射方向图仿真计算,表明这种缋源具有良好的电气性能,适合做抛物面天线馈源。This paper designs a double circular polarization、wideband monopulse feed.Use unipolar logarithmic periodic antenna array form with hexagonal arrangement.At 6 times the freguency get consistent patterns and good cross polarization isolation.Analysis of factors t and with simulation calculation of radiation pattern,indicates that this feed has good electrical properties,it is suitable for paraboloid antenna feed.
