摘要: 微帶天線振子上電流分布以及微帶天線陣中單元間相互耦合分析是微帶天線及其陣列分析的關鍵,由于此分析過程涉及到Sommerfeld積分,使得微帶天線上電流分布的求解十分煩瑣、費時。為此,本文提出了一種基于Chebyshev多項式展開的方法來計算Sommerfeld積分,進一步求出微帶天線上電流分布。結果表明,這種方法在保持較高計算精度的同時大大地提高了計算效率。Abstract: 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 sommerfeld integrals.The calculation results show that the presented method greatly improves the computing efficiency while retaining high accuracy.
