摘要
提出一种基于３Ｄ－ＦＤＦＤ（ＦｒｅｑｕｅｎｃｙＤｏｍａｉｎＦｉｎｉｔｅＤｉｆｅｒｅｎｃｅ）分析多层微带贴片天线的方法，在计算中采用非均匀网格减少对内存的需要，并且利用Ｇ．Ｍｕｒ’ｓ二阶吸收条件和场平均吸收条件截断网格。利用最小二乘法和压缩存储技术求解稀疏矩阵方程。计算了两种典型馈电的贴片天线，并与已有的结果作了比较，获得较好的一致性。
A generalized algorithm for the analysis of multilayered patch antenna is presented based on the 3D FDFD (Frequency Domain Finite Difference) method with non uniform meshes. The Mur’s ABCs of the second order and the ABCs based on the concept of field average are simultaneously applied at the terminating boundary mesh nodes. The compressed storage and least square method is adopted to solve the system of algebraic linear equations with sparse coefficient matrix, and is proved to be accurate and reliable compared with the reported data.
