摘要

本文介绍了一种Ka波段脊波导缝隙阵列的设计及仿真实验结果。为实现要求的35GHz-37GHz工作带宽,在中央馈电的5单元非对称分布脊波导辐射阵列的基础上,采用子阵划分以及多层级联波导功分器馈电的方式构建整个阵列。该天线在要求的频带范围内S11小于-15d B,高中低典型频点处方向图旁瓣和交叉极化分别低于-13d B和-40d B,且阵列增益保持稳定,达到了要求的性能指标。最后对未来工作方向进行了探讨。
This paper introduces the design of a ridged waveguide slotted array at Ka band, and the simulated results are proposed. To fulfill the required bandwidth from 35 GHz to 37 GHz, the whole array is constituted by sub-arrays and a multi-cascaded ridged waveguide power divider, based on a five-unit non-symmetric ridged waveguide radiated array with central feed. In the required bands, S11 is below-15 d B, and the side-lobe level and the cross-polarization is lower than-13 d B and-40 d B, respectively, while the gain of the array is nearly constant. Shown by the simulated results, the required performance is achieved. At last, some discussion about the future work is presented.
