提出了一种计算无限细线辐射元件平面阵列有源阻抗和电流分布的平面波展开矩法。阵列晶格可以是矩形或三角形。激励可以是平面波或递进相控电压源。每个辐射元件，包括馈线，可以是任何弯曲细导线的集合。给出了具有直馈线的直偶极子阵列、具有弯曲馈线的直偶极子阵列和具有直馈线的后掠偶极子（相对于阵列平面倾斜的臂）阵列的结果。实验观测到的馈线散射导致的阵列盲现象在理论上得到了验证。当偶极子臂相对于阵列平面倾斜时，这种效应不存在。
A plane wave expansion moment method is presented for computing active impedances and current distributions of infinite planar arrays of thin wire radiating elements. The array lattices can be rectangular or triangular. The excitations can be plane waves or progressively phased voltage sources. Each radiating element, including feedline, can be any collection of bent thin wires. Results are given for arrays of straight dipoles with straight feedlines, straight dipoles with bent feedlines, and swept back dipoles (arms inclined with respect to the array planes) with straight feedlines. The experimentally observed phenomenon of array blindness as a consequence of feedline scattering is verified theoretically. The absence of this effect when the dipole arms are inclined with respect to the array plane also is verified.
