摘要
为降低传统的波导缝隙阵列平板天线加工难度,提高环境适应性,分析了波导终端间隙结构对辐射波导输入阻抗的影响,提出了一种终端间隙结构的波导缝隙阵列平板天线,并给出了设计方法及22×4阵元Ka波段阵列的仿真结果.仿真结果表明:终端间隙尺寸较小时,终端间隙结构的波导缝隙阵列天线与传统的波导缝隙阵列天线性能基本一致;终端间隙结构的阵列在生产加工、环境适应性方面,具有较好的优势.
Abstract
In order to reduce manufacturing difficulty,and to improve environmental adaptability of waveguide slot planar array antenna,a waveguide slot antenna array with terminal gap structure was provided,and the influence of waveguide terminal gap structure on input impedance of radiated waveguide was analyzed.Basing on those analysis,the design method of waveguide slot antenna array was provided and a Ka band array was simulated with 22×4 elements.Simulation results show that the waveguide slot antenna array with terminal gap structure has equivalent electronic performance to traditional waveguide slot antenna array.Waveguide slot antenna array with terminal gap structure has advantage of production and acclimatization.
