【摘要】 本文介绍了一种圆极化天线罩,通过在一块微带板的两面加载周期性折线栅金属线,实现将线极化的电磁波转换为圆极化的辐射波。实验表明,本文设计的圆极化天线罩VSWR≤2的阻抗带宽为20%,轴比≤3d B的带宽为7%。样品的实测结果与仿真很好的吻合。验证了此圆极化天线罩的工程性并得到实际应用。更多还原

【Abstract】 This paper presents an circular polarizer. In order to realize the linear polarization to circular polarization, by loading periodicity meander-Line on substrate. The experimental results indicate that the Return Loss of less than-10 d B over bandwidths could be in excess of 20 percent, the Axial Ratio bandwidths could be in excess of 7 percent, and the simulated and measured results are in good agreement. This result is proved the circular polarizer is applied to engineering.更多还原
