本文对无限相控阵印刷偶极天线的扫描盲现象进行了全面的研究。一个严格和有效的矩量法程序被用来计算阵列阻抗与扫描角度。数据输入反射系数为各种元素间距和基板参数。一个简单的理论，从Floquet模式耦合到表面波模式的基础上的基板上，示出预测扫描盲区的发生。从波导模拟器的盲目条件下的测量证实了理论。
A comprehensive study of infinite phased arrays of printed dipole antennas is presented, with emphasis on the scan blindness phenomenon. A rigorus and efficient moment method procedure is used to calculate the array impedance versus scan angle. Data are presented for the input reflection coefficient for various element spacings and substrate parameters. A simple theory, based on coupling from Floquet modes to surface wave modes on the substrate, is shown to predict the occurrence of scan blindness. Measurements from a waveguide simulator of a blindness condition confirm the theory.
