摘要
为满足便携式大功率、宽容量多波束干扰系统的使用需求,设计了一种超宽带宽角覆盖的多波束喇叭发射天线阵。基于微带Rotman透镜的波束网络特性,发射天线阵采用弧形开口扇形脊喇叭天线结构,在6~18 GHz的工作频率范围内实现16波束输出,具备优异的波束指向性。俯仰面波束宽度为40°~70°,方位面实现±45°空域覆盖,拥有超宽角的波束覆盖能力。天线阵的有源驻波比小于3.0,能够承受大功率输出。同时,多波束喇叭发射天线阵结构设计紧凑,便于使用和安装。
To meet the usage requirements of portable high-power,multi-beam jamming systems with large capacity,a multi-beam horn transmitting antenna array with ultra-wideband and wide-angle coverage is designed.Based on the beam network characteristics of the microstrip Rotman lens,the transmitting antenna array adopts the structure of an arc-shaped opening sectorial ridge horn antenna,achieving 16 beam outputs within the operating frequency range from 6 to 18 GHz and possessing excellent beam directivity.The elevation beam width is 40°~70°,and the azimuth realizes±45° airspace coverage,having ultra-wide-angle beam coverage capability.The active standing wave ratio of the antenna array is less than 3.0,and it can withstand high power output.At the same time,the multi-beam horn transmitting antenna array structure is designed to be compact,facilitating usage and installation.
