| 摘 要： | 在全息天线构建原理的基础上,分析了源天线与理想平面波的干涉,以此确定全息结构的位置及全息天线的构成.同时对干涉极小值点的计算进行一定的简化,得到了具有普遍意义的计算全息结构位置的表达式.作为实例,利用金属全息结构与偶极子天线分别构建了一维、二维及准三维全息天线,并利用仿真软件HFSS对它们的辐射场进行了计算.计算结果表明,利用全息结构在一定程度上可以改善天线的辐射性能.最后,本文对全息天线的可能应用进行了探讨.

| Abstract: | Based on the fundamentals of holographic antenna construction,the interference of the source antenna and the ideal plane wave was analyzed.Consequently,the position of the holographic structure was determined.Furthermore the expression of the position of the holographic structure was achieved by simplifying the calculation of the minimal value of the interference field.As examples,the one-dimensional,two-dimensional and quasi three-dimensional holographic antennas were composed of the dipole and the metalli... |
