| 摘 要： | 采用理论分析和电磁仿真相结合的方法，详细分析了单脊波导中电磁场和表面电流的分布特点，并结合计算机辅助设计的方法，实现了一款工作于C波段单脊波导脊边双缝阵列天线.这种新型天线通过在单脊波导的脊边上成对开设倾斜缝隙来实现.仿真实验表明：本设计中天线的交叉极化降低到-50.26 dB，而天线的横截面尺寸仅为同频段标准矩形波导的47%.

| Abstract: | The distribution characteristics of electromagnetic field and surface current, which arise from the single ridge waveguide, are investigated by theoretical analysis and simulation, and then a novel slot array fed by single ridge waveguide is proposed for C band based on computer aided design. The array antenna is implemented by inserting slots in the ridge-walls of the single ridge waveguide. Therefore, the cross-polarization radiation of adjacent slots will be restrained for alternately tilted angles of slots. Simulation results show that the cross-polarization of array antenna is -50.26 dB, while the size is reduced by 53% compared to rectangular waveguide. |
