| 摘 要： | 将分形技术应用于多频段微带天线的设计是目前研究的热点。应用时域有限差分法(FDTD)对微带分形天线进行分析,采用同轴线的简化模型,使天线计算区域和同轴线区域合二为一,降低了计算复杂性。为了减少时间复杂度,采用Prony算法对FDTD时域波形进行外推。实验结果验证了分形天线的多频段特型,此天线在无线、个人移动通信中有应用前途。

| Abstract: | Using fractal technology to design multiband microstrip antenna is the hot studying field now. The Sierpinski microstrip fractal antenna in a Sierpinski carpet is analyzed by using Finite-Difference Time-Domain(FDTD) method. In order to decrease the computation complexity, the simplified model of coaxial line is used to make the computation area and coaxial line area to a uniform one. In order to reduce time complexity, Prony method is used to extrapolate time domain wave of FDTD. The result of experiment testifies multiband characteristic of fractal antenna and it is an attractive candidate for wireless and mobile communication application. |
