【摘要】 本文提出了一种基于机械开关的垂直面波束可变化的基站天线。通过在基站天线的馈电网络中加入机械开关以改变被激励的天线阵子数量,从而实现基站天线的垂直面波束宽度可重构的效果。这种垂直面波束可宽窄切换的基站天线,很好地解决了对覆盖范围有动态需求的移动通信网络场景的需求。使用机械开关的5单元双极化直线阵基站天线,能够在1.7～2.3 GHz内保持水平面典型波束宽度70°不变,而使垂直面典型波束宽度可以在70°和10°之间灵活切换。更多还原

【Abstract】 A base station antenna with adjustable vertical beam utilizing mechanical switch is proposed in this paper.By adding a mechanical switch to the feeding network of the base station antenna to change the number of the excited antenna elements,the vertical beam width of the antenna array is reconfigurable.This base station antenna with both wide and narrow vertical beams can meet the special requirements of mobile communication network scenarios with dynamic coverage.The 5-element dual-polarized base station antenna with the mechanical switch can keep the horizontal beam width of about 70°within 1.7-2.2 GHz,while the vertical beam width can be flexibly switched between 70° and 10°.更多还原
