| 摘 要： | 在ＰＣ机上应用扩展虚拟内存技术对一种单向介质辐射器（ＵＤＲ）模型进行了ＦＤＴＤ模拟，求出了远场区辐射方向图，得出的数值结果与实测值较好地吻合；讨论了前后功率流，证明了这是一种仅在正前方有极强辐射的定波束高增益天线原型。该天线适合移动通信的手机天线、防撞雷达、空间功率合成器等特殊应用。

| Abstract: | An unidirectional dielectric radiator for antenna is simulated with FDTD method on PC. The radiation pattern is calculated, and numerical results agree with experimental results. The simulation results indicate that this type of model with broad beam-width and good gain gives off radiation only in forward direction, so it can be used in mobile communication handset, anti-collision radar and space power combining circuits. |
