附图说明
图1为本发明选择天线的方法实施例的流程图；
图2为本发明选择天线的终端实施例的结构示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
图1为本发明选择天线的方法实施例的流程图，如图1所示，本方法包括如下步骤：
步骤101、接收所述第一天线获取到的特定信号。
首先，在终端上设置有第一天线和第二天线，第一天线和第二天线可以设置在终端的后盖上或者其他部位，在此不加以限制；其中，第一天线为主天线，可以接收无线充电信号和NFC信号，并且可以进行无线充电工作，而不能进行NFC工作；第二天线为辅助天线，将第一天线与第二天线组合成第三天线，该第三天线为NFC天线，可以用于进行NFC工作；这里需要说明的是，第一天线与第二天线的类型和尺寸可以根据实际需求进行设置，在此不加以限定。
在本步骤中，终端接收所述第一天线获取到的特定信号，其中，特定信号包括了无线充电信号和/或NFC信号。
另外，终端可以以各种形式来实施，例如，本发明实施例中描述的终端可以包括诸如：移动电话、智能电话、笔记本电脑、数字广播接收器、个人数字助理(PDA)、平板电脑(PAD)、便携式多媒体播放器(PMP)、导航装置等等的移动终端。
步骤102、根据所述特定信号确定所述特定信号的类型。
在本步骤中，终端根据接收到的所述特定信号来确定所述特定信号的类型，所述特定信号的类型包括了无线充电信号类型或NFC信号类型。
具体的，终端是根据所述特定信号中携带的信号频率和初始化包头来确定所述特定信号的类型；终端检测所述特定信号中携带的信号频率和初始化包头，如果所述信号频率在200KHz(千赫兹)到1MHZ(兆赫兹)之 间、且所述初始化包头符合无线充电信号标准(01XXXXXX)，则判定所述特定信号为无线充电信号类型；如果所述信号频率在13.56MHz或13.56MHz附近、且所述初始化包头符合NFC信号标准(10XXXXXX)，则判定所述特定信号为NFC信号类型；
若所述特定信号中既包括所述无线充电信号又包括所述NFC信号，则判定所述特定信号为无线充电信号类型。
步骤103、根据所述特定信号的类型选择对应的天线。
在本步骤中，根据特定信号的类型选择对应的天线，其中，可选的天线可以为第一天线或者由第一天线与第二天线电连接组成的第三天线；具体的，当所述特定信号为无线充电信号类型时，执行步骤104；当所述特定信号为NFC信号类型时，执行步骤105。
步骤104、当所述特定信号为无线充电信号类型时，将所述第一天线与无线充电电路电连接，通过所述第一天线进行无线充电。
终端在确定所述特定信号为无线充电信号类型后，会将设置在终端上的第一天线(主天线)通过选择单元与无线充电电路电连接，将第一天线(主天线)获取到的无线充电信号通过无线充电电路转化成电能供终端的电池进行充电。
步骤105、当所述特定信号为NFC信号时，将所述第一天线与所述第二天线电连接组成第三天线。
终端在确定所述特定信号为NFC信号类型后，会将设置在终端上的第一天(主天线)线通过选择单元与第二天线(辅助天线)并联电连接组成第三天线(NFC天线)。
无线充电天线一般要求电感值为12μH(微亨)，NFC天线一般要求电感值为1μH左右，所以在本实施例中第一天线(主天线)为标准的无线充电线圈，电感值为12μH，第二天线(辅助天线)的存在主要是为了与第一 天线(主天线)并联电连接，形成第三天线(NFC天线)，通过选择单元将第一天线与第二天线并联的方式将第三天线的电感值调节到1μH左右，这样就不需要调节接线长度来实现电感值的改变，使电感值更容易调节；同时，硬件确保第一天线与第二天线的信号线平行，激励电流为同向电流，第一天线与第二天线之间还可以产生互感，互感的大小与第一天线与第二天线之间的相对位置与距离相关，互感和第一天线与第二天线自身的电感正向叠加，不仅减小了无线充电信号与NFC信号之间相互干扰，还加强了NFC天线的磁感应强度，同时也可以增加NFC近场通讯的通讯距离和感应面积，提高了性能。
步骤106、通过所述第三天线进行NFC通信。
终端在通过选择单元将第一天线与第二天线并联组成第三天线后，由于事先第二天线与NFC电路电连接，所以终端就可以利用第三天线获取到NFC信号后通过NFC电路，完成信息交互。
本发明实施例提供的选择天线的方法可视为无线充电和近距离无线通信NFC共用天线的方法，通过终端中的选择单元将第一天线与第二天线并联组合成第三天线，使第三天线的电感值满足NFC的要求，这样就不需要调节接线长度来实现电感值的改变，使电感值更容易调节；同时，硬件确保第一天线与第二天线的信号线平行，激励电流为同向电流，第一天线与第二天线之间还可以产生互感，互感的大小与第一天线与第二天线之间的相对位置与距离相关，互感和第一天线与第二天线自身的电感正向叠加，不仅减小了无线充电信号与NFC信号之间相互干扰，还加强了NFC天线的磁感应强度，同时也可以增加NFC近场通讯的通讯距离和感应面积，提高了性能。
