摘要
针对工程实际应用,本文深入分析了主模圆锥喇叭馈电多波束抛物面天线的辐射特性,通过快速哈特莱变换(FHT)对辐射场积分的处理,利用软件优化仿真得到了抛物面多波束天线设计的关键参数和辐射方向图,大大简化了工程设计中各设计参数的复杂考虑和计算量,最后利用优化结果设计了8波束抛物面天线。该分析对工程设计有着极其重要的参考价值。
Aiming at engineering application, we analyzed radiation of multi-beam parabolic reflector antenna with conical horn feed source. On the basis that the radiation integral was evaluated rapidly via the FHT, the key parameter and radiation pattern of parabolic reflector antenna were derived through simulation and optimization, so as to simplify the design and the computation of parameters in engineering. A millimeter-wave parabolic reflector antenna of eight beams was designed by the optimized results. This study is instructive to engineering design of multi-beam parabolic reflector antenna.
