| 摘 要： | 提出一种抑制交叉极化的新方法,通过调整天线与地板的间距,使得交叉极化反射波与直射波相消,从而达到抑制交叉极化的目的。这种方法克服了传统方法的弊端,具有结构简单、实现方便、交叉极化抑制效果良好且对主极化方向图影响小的优点。理论分析、仿真结果与实测结果取得了一致。最终将交叉极化电平降低了6dB,证明了该方法的正确性和有效性。

| Abstract: | A new method for cross polarization suppression of traveling-wave-fed sidewall slot arrays is presented.The space between the antenna and the ground is regulated to make the reflect wave of cross polarization counteract the direct wave,so the cross polarization is suppressed.There are some advantages of this method,such as,simple structure,easy realization,good suppression,little affection to copolarization sidelobe,and so on.Good agreement of test results with theory and simulation validates the new design... |
