| 摘 要： | 研制了一款用于微波频段频谱监测以及测向的,可以覆盖900MHz～11GHz的高增益超宽带喇叭天线。此款天线采用在传统喇叭天线腔体中加入一对渐变的寄生脊的方法,优化馈电部分同轴到双脊波导的转换,实现了同轴到波导的宽带匹配。最终天线实现了数十倍频程内驻波比小于2,增益在8～13dB之间,并且具有稳定的辐射方向图。

| Abstract: | A ultra wide band horn,which is used in radio monitoring for microwave spectrum detecting and direction finding,is proposed.It can cover a wide frequency band from 900MHz up to 11GHz and achieve high gain.The antenna is derived from the traditional pyramidal horn in which extra ridges are placed.It is fed by coax-to-ridged-waveguide,which is optimized for good matching.It shows that the VSWR(Voltage Standing Wave Ratio) is lower than 2,gain is 8～13dB and stable pattern is acheived in a broad band. |
