摘要
用自适应修正特征基函数法(AMCBFM)分析微带天线的电磁散射特性。以矩量法和体面积分方程为基础,把微带天线介质部分用四面体网格剖分,对应于SWG基函数;微带天线导体部分用三角形网格剖分,对应于RWG基函数。分析了2×2微带天线阵列的单站RCS和7×7微带天线阵列的双站RCS。结果表明:AMCBFM能有效分析微带天线阵列的电磁散射特性,且具有大幅度降低阻抗矩阵大小、减少计算机内存需求等优点。
Electromagnetic scattering characteristics of the microstrip antenna array is analyzed by using the adaptively modified characteristic basis function method （AMCBFM）. Volume electric field integral equation and SWG basis function are applied to the material region, while the surface electric field integral equation and RWG basis function are applied on the conducting sur- face of the microstrip antenna array. The method of moments （MoM） is used to convert the integral equation into a matrix equation. The bistatic RCS of 7 × 7 microstrip antenna array and the monostatic RCS of 2 × 2 microstrip antenna array are ana- lyzed numerically. The results indicate that the proposed method has a series of merits： reducing the size of the matrix equation into a small level and saving the memory requirments.
