摘要

提出了一种新的用于微带天线阵分析的多级格林函数插值方法。该方法采用分层介质的并矢格林函数作为核，有效地减少了未知数的数量。然后通过径向基函数(rbf)实现这类格林函数的插值。比较了拉格朗日插值和RBF插值的插值精度。最后以30 × 30微带贴片阵列为例，验证了该方法的准确性和有效性。

A multilevel green's function interpolation method for the analysis of microstrip antenna arrays

A new multilevel Green's function interpolation method (MLGFIM) used for the analysis of microstrip antenna arrays is presented. Dyadic Green's function for a layered medium is used in this method as the kernel to efficiently reduce the number of unknowns. Interpolation of this type of Green's function is then implemented by radial basis functions (RBFs). The interpolation accuracies using Lagrange and RBF interpolations are compared. A numerical example of a 30 by 30 microstrip patch array is given to validate the accuracy and efficiency of the proposed method.
