引 言 通常的相控阵天线,为改变射束方向所需的天线阵面相位梯度,是通过改变分立元件的相位来实现的。本文介绍的电扫描法则采用了改变人工介质透镜折射率的原理。
Introduction The usual phased-array antennas, the antenna array phase gradients needed to change the beam direction, are achieved by changing the phase of the discrete components. This article describes the principle of scanning used to change the refractive index of artificial media lens principle.
