中文摘要:介绍HFSS在漏波长槽波导天线口径场诊断中的应用,通过合理的子网格设置仿真得到辐射长槽上精确的口径场。采用提取的口径场分布反演得到天线远场方向图,将其与仿真得到的方向图相比,非常吻合,证明这种诊断方法正确有效。根据口径场诊断结果,对天线结构进行调整优化,达到明显的优化效果,天线副瓣明显降低,负载吸收率与理论设计非常吻合。

Aperture field diagnosis of leaky-wave long slot waveguide antenna based on HFSS
Abstract:The application of HFSS in aperture field diagnosis of leaky-wave long slot waveguide is introduced. The accurate aperture field of radiant long slot is obtained through reasonable sub-grid setting simulation. The antenna far-field pattern is obtained using the inversion of extracted aperture field distribution, which is very consistent with the pattern obtained by simulation. It is proved that the diagnosis method is correct and effective. According to the diagnostic results of aperture field, the antenna structure is adjusted and optimized to achieve obvious optimization effect. The antenna side lobe is significantly reduced, and the load absorption rate is very consistent with the theoretical design.
