摘　　要：应用基于光滑的、紧支撑的Cohen-Daubechies-Feauveau(CDF)双正交尺度函数的时域多分辨分析(MRTD)方法分析天线的辐射,推导了MRTD迭代方程及各向异性理想匹配层(APML)吸收边界公式,并对天线的重要参数如:S参数,输入阻抗,辐射方向图等进行计算。计算结果显示:MRTD的结果与传统的FDTD的结果相比一致,说明MRTD在不牺牲精度情况下,节省大量计算资源。Multiresolution time domain （MRTD） scheme is presented with application to antenna radiation. We employ Cohen-Daubechies-Feauveau （CDF） biorthogonal scaling function which owns nice smoothness properties while retaining compact support. The strict calculation formula and the absorbing boundary conditionanisotropic matched layer （APML） formula are derived. The important parameters of the antenna are calculated, such as the S parameter, input impedance, radiation patterns and so on. The results and those obtained by use of the conventional FDTD technique are almost the same. The important memory savings are yielded by the MRTD without sacrificing solution accuracy.
