    • An RFID tag and a method for optimizing a Yagi-Uda antenna for a RFID inlay or integrated circuit is provided. The method has steps comprise: 1) selecting an electrically conductively first element; 2) generating an electrically conductive second element by taking a mirror image of the electrically conductive first element and trimming the second element; 3) generating a third element” along a line of axis of symmetry of the first two elements and on the opposite side of the first element as the electrically conductive second element; 4) adjusting the distance between the first three elements for optimum performance using Et(x)=EXP[a−x·b]+E∞; and 5) optionally, if the electrically conductive first element does not contain an IC (integrated circuit) or RFID inlay, then adding an IC or RFID inlay adjacent to/or physically touching the electrically conductive first element along the line of symmetry.
    • 提供RFID标签和用于优化用于RFID镶嵌或集成电路的八木Uda天线的方法。 该方法具有以下步骤:1)选择导电第一元件; 2)通过拍摄导电的第一元件的镜像并修整第二元件来产生导电的第二元件; 3)沿着第一两个元件的对称轴的线和第一元件的与导电的第二元件相反的一侧产生第三元件; 4)使用Et(x)= EXP [a-x·b] +E∞调整前三个元件之间的距离以获得最佳性能; 和5)可选地,如果导电的第一元件不包含IC(集成电路)或RFID嵌体,则沿着对称线相邻或物理地接触导电的第一元件添加IC或RFID嵌体。
