发布时间:2018-10-15 09:41
【摘要】:本文研究了一种工作在Ku和K波段应用于雷达天线罩的圆极化变换器,线-圆极化变换器通过在天线辐射前方添加多层极化变换层,可使天线辐射的线极化波转换为圆极化波,由此可实现雷达发射圆极化电磁波的目的.极化变换层工作原理是对入射电磁波的平行分量滞后垂直分量超前从而实现圆极化,其主要通过把印刷电路板上的金属层腐蚀成金属栅格线.与传统线-圆极化变换器相比,新型线-圆极化变换器能有效实现小型化,在军事上拥有实际应用价值.
[Abstract]:In this paper, a circular polarization converter used in Ku and K-band radome is studied. By adding multi-layer polarization transform layer in front of antenna radiation, the linear polarization wave of antenna radiation can be converted into circular polarization wave. Thus the aim of radar transmitting circular polarization electromagnetic wave can be realized. The principle of polarization transformation layer is to advance the parallel component of the incident electromagnetic wave and realize the circular polarization, which is mainly by etching the metal layer on the printed circuit board into a metal grid line. Compared with the traditional wire-circular polarization converter, the new wire-circle polarization converter can realize miniaturization effectively and has practical application value in military.
