本文借助旋转矩阵和矢量叠加原理,详细介绍了能使通信容量加倍的双圆极化器的工作原理和实施方案。从文章中的推导可知分别输入正交模变换器E臂和H臂的两个互相垂直的线极化波,通过两只可旋移相器(90°和180°移相器)之后,变为极化方向彼此垂直的单位复矢量表达的两个椭圆极化波。并且可知,从矢量正交的角度去考虑,(?)与(?),不正交,而(?)与(?)是正交的。此外,考虑到两个移相器有损耗和相位误差,所
In this paper, with the help of the principle of rotation matrix and vector superposition, the working principle and implementation scheme of double circular polarizer that can double the communication capacity are introduced in detail. From the deduction in the article, it can be seen that the two mutually perpendicular linearly polarized waves of the E-arm and the H-arm of the Orthogonal mode converter are respectively input into two linearly polarized phase shifters (90 ° and 180 ° phase shifters) Two elliptically polarized waves expressed by a unit complex vector with polarizations perpendicular to each other. And we can see from the vector orthogonal point of view, (?) And (?), Not orthogonal, and (?) And (?) Are orthogonal. In addition, considering the two phase shifters have loss and phase error
