[0028] 所述底柱 1与风车头 3之间设有轴承； 可以减少摩擦， 降低损耗。 本实施例所述 的一种扇叶可转向的风力发电风车， 所述扇叶 2为三个， 围绕风车头 3间隔 120度 设置。 本实施例所述的一种扇叶可转向的风力发电风车， 第一旋转电机 4的动力 输出端于第一转轴连接处围绕设有轴承； 风车头 3的前端为锥面。 [0029] 本实施例所述的一种扇叶可转向的风力发电风车， 所述抗电辐射天线包括有矩 形反射板 nl， 矩形反射板 nl上设有上下对称的微带辐射阵， 每个微带辐射振包 括有两个左右对称的微带子阵以及连接两个微带子阵的阵桥 n2; 所述每个微带 子阵包括有一个基臂 n3， 基臂 n3两端分别设有桥支臂 n4， 两个桥支臂 n4呈 60度 夹角； 一个桥支臂 n4上向垂直这个支臂的方向上延伸有 Π形的过渡臂 n7， 另一个 桥支臂 n4上向与一个支臂平行的方向上延伸出有第一辐射臂 n8， 第一辐射臂 n8 向过渡臂 n7—侧、 且与第一辐射臂 n8垂直的方向上延伸出 F形的第二辐射臂 n9， 第二辐射臂 n9与第一辐射臂 n8垂直连接的一个辐射臂上还设有与第一辐射臂 n8 平行的第三辐射臂 n91 ; 另一个桥支臂 n4还向外侧延伸出 T形杆 N5， T形杆 N5未 与另一个桥支臂 n4连接的臂与桥支臂 n4平行。
[0030] 为达到较优的抗电磁场特性， 且又要满足远距离通信的辐射要求， 设计的通信 天线经过不下 2000次的调整和修改设计出该天线， 具体的测试结果如下： 如图 6 ， 本天线的仿真与测试的 IS11I参数标准一致， 测试的 10-l ldB阻抗带宽是 28.5% ， 阻带 IS11I接近于 0。 如图, 7， 本天线的增益曲线比较吻合， 测试通带内平均增 益 8.2dBi,并且在通带边沿有很高的滚降度， 在很宽的阻带内带外抑制超过 20dBi ， 0〜10GHz范围内有较好的滤波效果， 因此可以得到其具备较强的抗电磁场能 力; 本发明实施例的带内效率高达 95%。 参阅图 8， 中心频率 5GHz的归一化方向 图； 最大辐射方向在辐射体的正上方， 主极化比交叉极化大 25dBi以上。 通带内 其他频率的方向图与 5GHz的方向图类似， 整个通带内方向图稳定， 证明其通信 性能较高； 上述天线为非尺寸要求天线， 只要在弯折方向上、 设置的孔、 洞的 方式上达到上述要求， 均可达到上述实验结果； 上述测试均是在模拟 10KV的风 力车 lm范内环境下进行测试。

[0033] 如需获得上述稳定性能， 本天线的尺寸具体可以优化为： 矩形反射板的宽为 42 mm, 高为 49mm; 基臂的宽为 1.7mm， 高为： 4.7mm; 本文中记载的标准线宽设 定为 0.85mm; 桥支臂的线宽为标准线宽， 最长边为 14.5mm; 过渡臂的线宽为： 0.7mm; 高为 2.1mm， 两个纵臂距离： 2.9mm; 第一辐射臂的线宽为标准线宽， 其最长边为 7.62， 第二辐射臂的线宽为标准线宽， 与第一辐射臂连接的纵臂长为 6.0mm, 两个横臂最长边均为 4.2mm; 第三辐射臂线宽为标准线宽， 最长边为 4.2 mm; T形杆的线宽为标准线宽， 纵臂最长边为 0.9,mm， 横臂为平行四边形， 因 此其长边为 5.8mm; 耦合臂的线宽为二分之一的标准线宽， 并且边外边的边长为 4.0mm; 隔离臂的底边边长为： 2.85mm; 顶边边长为： 3.8mm; 高为： 2.1mm。 圆弧形凹陷的半径为 0.8mm。 微带连接线均不做要求。 其中， 桥支臂、 第一辐射 臂、 第二辐射臂、 第三辐射臂的自由端为楔形角锐角为 30度。 圆形凸起的直接 不超过 :0.8mm,两个圆形凸起的中心距离不超过 1.2mm。
[0034] 以上所述仅是本发明的一个较佳实施例， 故凡依本发明专利申请范围所述的构 造、 特征及原理所做的等效变化或修饰， 包含在本发明专利申请的保护范围内
