| 摘 要： | 采用时域有限差分（FDTD）全波分析方法分析平面带宽Vivaldi天线，运用Mur二阶吸收边界和局部吸收负载技术研究不同类型槽线的特性阻抗，所得槽线特性阻抗同矩量法及实验结果进行比较，验证FDTD方法的性和可行性，为消除普通Vivaldi天线同轴馈电接头与槽线一臂的并联电容对宽带设计的不利影响，运用Mur二阶吸收边界的对变形平面宽带Vivaldi天线整体建模，得到远场方向图，实现了天线的宽带设计。

| Abstract: | Full wave method FDTD was used to design and analyse wideband planar antennas, in order to acquire the impedance of three kinds of slotlines, Mur's ABCs of the second order and partial absorbing load was taken into account to reduce the reflection on the boundary conditions. Comparison with the MoM and Serenade software as well as experiments verified the accuracy and readiness of this method. Finally, the pattern of Vivaldi antenna (based on the double sided slotline) was obtained. |
