此时可以参阅图2,图2为本公开实施例提供的天线结构的结构示意图,第一馈线的一端与第一馈电片连接,另一端与第一馈源6连接;第二馈线的一端与第二馈电片连接,另一端与第二馈源7连接。第一耦合片1在第二耦合片2的正上方,第一耦合片1和第二耦合片2均在接地板3的上方。第一耦合片1和第二耦合片2之间的距离可选的可以为0.22mm,第二耦合片2和接地板3之间的距离可选的可以为0.6mm。第一馈电片跟第一耦合片1之间的距离,可以与第一馈电片跟第二耦合片2之间的距离相等,该距离可选的可以为0.1mm。同理,第二馈电片跟第一耦合片1之间的距离,可以与第二馈电片跟第二耦合片2之间的距离相等,该距离可选的亦可以为0.1mm。

可选的,所述第一耦合片1和所述第二耦合片2的中心在同一条直线上,该直线垂直于所述第一耦合片1和所述第二耦合片2。
