【摘要】 提出了一类基于平行耦合槽线设计的极化旋转表面结构。该类型结构单元包含一端开路、另一端短路的槽线,槽线分别印刷在竖直(x-轴)和水平(y-轴)方向的印制电路板当中。当入射电磁波的极化沿着竖直方向时,竖直方向的槽线发生谐振,并耦合到竖直/水平方向的槽线,实现电磁波的极化旋转。利用滤波器的综合原理,对所设计的极化旋转表面进行综合设计,并对设计的极化旋转表面进行仿真、加工和测试。该类型极化旋转表面具有通带内高极化转换率和大角度斜入射稳定性的特点。更多还原

【Abstract】 In this paper,a kind of polarization-rotating surface(PRS) based on parallel-coupled slot-lines is proposed,which can realize polarization rotation.The unit cell of the structure consists of open-short-ended slot-lines,which are etched on the orthogonally inserted PC.B pieces along the vertical(x-axis) and horizontal(y-axis) directions,respectively.As a linearly polarized plane wave is oriented along the x-axis,the vertical slot-line is resonated,and then coupled to another slot-line along the x-or y-axis,resulting in polarization rotation.The synthetic approach of filters is employed to design the proposed PRSs.Finally,two types of the designed PRSs were simulated,fabricated,and measured.The proposed PRSs feature high polarization conversion ratio in the operating band and great angular stability for large incidence angles.更多还原
