摘　　要：微带天线振子上电流分布以及微带天线阵中单元间相互耦合分析是微带天线及其阵列分析的关键,由于此分析过程涉及到Sommerfeld积分,使得微带天线上电流分布的求解十分烦琐、费时。为此,本文提出了一种基于Chebyshev多项式展开的方法来计算Sommerfeld积分,进一步求出微带天线上电流分布。结果表明,这种方法在保持较高计算精度的同时大大地提高了计算效率。The determination of the current distribution on the dipoles of microstrip antennas and the coupling between elements of arrays are especially important for the analysis of microstip antennas and arrays . Unfortunately, the calculation is tedious and time-consuming because of the existing of the Sommerfeld integrals. A new method is proposed in this paper to calculate the current distribution by using Chebyshev decomposition to deal with the som-merfeld integrals. The calculation results show that the presented method greatly improves the computing efficiency while retaining high accuracy.
