摘要
针对常规飞机、卫星等的几何形状 ,用时域有限差分法 (FDTD)分析了圆柱形良导体外形 (用以模拟飞机卫星等的机体 )对机载 /星载天线 (文中采用了线天线 )辐射特性的影响。通过改变柱形的直径和长度 ,对天线辐射方向图的变化进行了大量的研究 ,并得出了一些规律性的结果。
In this paper, according to the usual shapes of aircrafts, FDTD was applied to analyze the affection of cylindrical conductor on antennas, which are fixed on the conductor. By adjusting the length and diameter of the cylindrical conductor, the affections on the pattern of a linear radiating source were calculated. Some interesting results have been gotten which are useful for the prediction of electromagnetic compatibility between antennas and aircrafts.
