| 摘 要： | 本文分析了一种具有超宽带特性的平面喇叭天线的阻抗和辐射特性.这种平面喇叭采用了新型的平衡馈电方式,结构简单,性能良好.采用时域有限差分方法(FDTD)分析天线时,吸收边界采用了完全匹配层技术(PML),并用环路径分方法(CP)处理了喇叭脊间窄缝,计算结果与实测数据比较,两者十分吻合.

| Abstract: | The impedance and radiation characteristics of an ultra wide band planar horn antenna are analyzed theoretically and calculated using FDTD method in this paper.This horn antenna is characterized with U balun,simple construction and perfect performance.Perfectly Matched Layer(PML) technique is applied as absorbing boundary conditions,and Contour Path Method (CP) is used to conform to the curved slot between the two ridges in FDTD simulation.Good agreements between calculated and measured results are obtained. |
