| 摘 要： | 文章研究了单脉冲双极化天线阵列。天线阵混合馈电微带单元由共面微带线馈电和缝隙耦合微带线馈电两者结合形成,"十"字形微带单脉冲比较器与天线阵同面,具有结构紧凑、加工方便和成本低的优点。经仿真验证,在工作频带内其辐射单元双端口隔离度高于34dB;并且2个极化端口在其对应主平面方向的副瓣电平均低于-20dB。天线可适用于新一代多极化雷达系统。

| Abstract: | A monopulse dual-polarized antenna array was studied, which was based on proximity-coupled combine H-shaped slot-coupled microstrip patch antenna units. The cross type comparator and the antenna array are located on the same layer resulting in the advantages of being compact, easy manufacturing and low cost. The results show that the isolation between the excitation ports is greater than 34dB over this frequency range. The side-lobe level is lower than -20dB in both horizontal and vertical ports. This array can be used in radar system for its high performance. |
