该天线是经过调频特性的理论计算得出的尺寸大小，并经过实际设计验证的经验值，跟板材及环境都有关系。

按如下规格设计最远距离（无遮挡）可达20米。

图 1
2.1.2 布线要求
首先，建议将天线按尺寸设计成元件封装，方便摆放及后续项目设计，并可以防止拖动造成尺寸大小变化，而来回修改。

其次，该天线是与地线连接的，天线有效部分的周围及其下层（即
背面）不应用有元器、布线，更不应该铺铜，否则影响信号发射和接收，甚至无法正常工作。

第
三，该天线的接地点要求大面积接地，并多打过孔。

第四，该天线要求设计在PCB板的板边，尽量朝前面板，并要求周围避开铁质结构件。

外引天线的线材要求采用
50欧高频屏敝电缆，并在尾部去掉3CM长的屏敝层。

线头的中间信号线焊接在天线输出端，而
屏敝铁线也应该焊在就近地线位置，该天线尾部应放置于前面板靠前位置或者引至铁壳之外。
