摘要
文中设计了一种新型超宽带平衡对跖Vivaldi天线单元和阵列。研究分析了主要结构参数对天线性能的影响,通过增加金属隔板、接地柱、减小天线剖面高度等方式,将天线单元的阻抗带宽由1.7个倍频程提升至5个倍频程。该新型天线单元具有阻抗带宽较宽、结构尺寸小的特点,是一种较为理想的超宽带阵列天线单元。在单元优化的基础上,文中对8×8的超宽带天线阵列性能进行了研究,结果表明该天线阵列具有良好的阻抗带宽和辐射性能。
A novel ultra-wideband( UWB) balanced antipodal Vivaldi antenna element and array with wide-angle scanning is designed. The influence of the main structural parameters on the antenna performance is analyzed. The impedance bandwidth of the antenna element is improved from 1. 7 octaves to 5 octaves by adding metallic partitions,metallic poles and reducing the height of the antenna. The novel antenna element not only has a wide impedance bandwidth,but also a smaller structure size. The length and width of the antenna element is only half of the wavelength corresponding to the highest frequency. It is an ideal UWB wide-angle scanning array antenna element. On the basis of element optimization,the performance of 8 × 8 UWB array is studied. The results show that the array has a wide impedance bandwidth and good radiation performance.
