本发明实施例，通过将 PCB板 20和主天线 30设置在数据卡的机壳 10 的内部空腔中， 同时在机壳 10的内部空腔中还设置有与接头 40电连接的 接头金属转轴 50; 而接头金属转轴 50与接头 40的电连接， 形成数据卡的 分集天线， 其能够与主天线 30共同形成数据卡的天线。 这样， 由于不需单 独设置分集天线， 从而减小了数据卡的外形尺寸， 保证了数据卡的外形美 观， 从而降低了数据卡的生产成本。
在上述实施例中， 在 PCB板 20上设置有第一馈电部 21和第二馈电部 22; 其中， 第一馈电部 21与主天线 30连接、 用于对主天线 30进行馈电， 第二馈电部 22与接头金属转轴 50连接、用于对接头金属转轴 50进行馈电。 第一馈电部 21对主天线 30馈电； 而由于接头金属转轴 50与接头 40的电 连接， 第二馈电部 22对接头金属转轴 50馈电， 这样， 接头金属转轴 50与 接头 40电连接后， 以及主天线 30， 便形成数据卡的两个天线， 同时工作。
通过设置第一馈电部 21， 使其与主天线 30连接并对主天线 30进行馈 电， 同时设置第二馈电部 22，使其与接头金属转轴 50连接并对接头金属转 轴 50进行馈电， 将接头金属转轴 50与接头 40电连接； 这样， 接头金属转 轴 50与接头 40的电连接， 以及主天线 30， 便形成数据卡的两个天线， 同 时工作， 从而为提高数据卡的下载速率提供了有力的保证。
在上述实施例中， 数据卡还包括接头连接线 60， 该接头连接线 60的两 端连接 PCB板 20和接头 40。接头连接线 60连接 PCB板 20的一端与 PCB 板 20为电连接， 通过 PCB板 20的供电， 从而将接头 40连通。
参照图 3和图 4，图 3为本发明数据卡第二实施例中第一种实施方式的 结构示意图； 图 4为本发明数据卡第二实施例中第二种实施方式的结构示 意图。

本发明实施例， 通过在机壳 10的内部空腔中设置有与接头 40电连接 的接头金属转轴 50， 使得接头金属转轴 50与接头 40的电连接， 形成数据 卡的分集天线。 并且， 当接头 40插接在用户终端上后， 接头金属转轴 50 和接头 40， 以及用户终端中的金属体之间的电连接， 共同形成了数据卡中 天线的辐射体， 从而避免了用户终端中的金属体对数据卡的辐射性能的影 响， 使得数据卡的辐射能力更强， 进而有效地提高了数据卡的无线性能。
