In this article, we investigate the radiation and impedance properties of arrays of tilted dipoles. A spectral periodic method of moments (MoM) is developed for the analysis of infinite arrays with arbitrarily tilted dipole elements, in free space or with a backing reflector. With the aid of this analysis method, the radiation characteristics of arrays of stacked dipoles over a ground plane are studied, explaining the variation of the patterns as a function of the interelement distance and the angle of inclination of the elements. Finite linear arrays of tilted dipoles are also investigated, to assess the dependence of the array characteristics on the number of elements. The developed method can be used to design arrays with nonsymmetric radiation patterns for angular filtering or pattern shaping.

倾斜偶极子阵列的分析：阻抗和辐射特性

在本文中，我们研究了倾斜偶极子阵列的辐射和阻抗特性。开发了一种光谱周期矩法 (MoM)，用于分析具有任意倾斜偶极子元件、在自由空间中或带有背衬反射器的无限阵列。借助这种分析方法，研究了接地平面上堆叠偶极子阵列的辐射特性，解释了作为元件间距离和元件倾斜角函数的模式变化。还研究了倾斜偶极子的有限线性阵列，以评估阵列特性对元件数量的依赖性。所开发的方法可用于设计具有非对称辐射方向图的阵列，用于角度滤波或方向图整形。
