摘要:
阵元间互耦是分析阵列天线问题中的难点之一,常用矩量法加以分析.这里提出了一种改进的矩量法,把线天线等效为带状线,用RWG基函数作为阵元表面电流的展开函数,精确计算了阵元之间的互阻抗矩阵,从而在分析问题时计入了互耦的影响.以等间距的Chebyshev线阵为例,分析讨论了在阵元位置和副瓣电平不同的情况下,互耦对阵列方向图的影响.得到了一些有用的结论,对以后深入研究互耦问题有一定的指导意义.
Abstract:
Mutual coupling of elements in array antennas often seriously affects the outcome of array antenna analysis using moment method. This paper is mainly devoted to an improved moment method, in which the wire antenna is equalized as a thin strip; RWG basis function is used as the expansion function of surface currents of array elements. With this method, the mutual impedance matrix can be evaluated exactly, and the effect of mutual coupling is taken into account in analysis. Considering an example of Chebyshev arrays with equal distance between elements, the effects of mutual coupling on array patterns were analyzed under situations with different array element location and sidelobe levels. Simulation results offer some useful conclusions for future study.
