摘要
采用基于有限元法(Finite Element Method,FEM)的仿真软件设计了一种工作在C波段的高增益水平极化波导缝隙全向天线。通过在一组装扁矩形波导两个宽面上开设数条对穿辐射裂缝构成缝隙天线阵列,并采用同轴探针直接馈电,使该天线具有较高的增益和较好的不圆度。实测结果与仿真计算结果吻合良好。
A C-band high gain horizontally polarized omnidirectional waveguide-slot antenna is designed by the simulaton software based on Finite Element Method （FEM）. The antenna with high gain and good omnidirection, which is fed by a coaxial probe, is based on a packed compressed rectangular waveguide with several radiation slots fabricated on the two opposite broadsides. The experimental result is in good agreement with the simulation result.
