【摘要】 本文设计了一种超宽带双脊圆锥喇叭天线,对常规喇叭天线加入渐变的脊结构,直圆波导内加入对称的环状结构,并截断脊波导与脊之间的过渡结构,实现了小型化和宽带化。通过优化脊曲线和脊末端的圆弧倒角,可以在要求的频段1 GHz～18 GHz得到理想的驻波比,仿真分析表明该天线具有良好的频带特性和方向图特性,对天线测量系统中探头的应用有一定的参考价值。更多还原

【Abstract】 In this paper,we designed an ultra-wideband dual-ridge conical horn antenna,adding a gradient ridge structure to the conventional horn antenna,adding a symmetrical ring structure inside the straight circular waveguide,and truncating the transition structure between the ridge waveguide and the ridge to realize miniaturization and wideband.By optimizing the ridge curve and the rounded chamfer at the end of the ridge,the ideal VSWR can be obtained in the required frequency band 1 GHz～18 GHz.The simulation analysis shows that the antenna has good band characteristics and directional map characteristics,which has some reference value for the application of the probe in the antenna measurement system.更多还原
