在另一实施方式中，请参阅图6，图6为另一实施例中图1提供的电子设备中的中框的俯视图。在本实施例中，所述第一缝隙130仅对应开设第二缝隙1221的边框120。
以下实施例中以所述第一缝隙130对应部分第一边框121及部分第二边框122为例进行详细说明。在示意图中，所述第一边框121为电子设备的长边框，所述第二边框122为电子设备的短边框。

请再次参阅图2及图3所述第一缝隙130开设于所述中框本体110邻近所述第一边框121及所述第二边框122处，且所述第一缝隙130贯穿所述中框本体110在厚度方向上的两个表面。所述第二缝隙1221连通所述第一缝隙130且将所述第二边框122切割成两部分。具体地，所述第二边框122包括第一表面1222、第二表面1223、以及第三表面1224，所述第一表面1222为所述第二边框122背离所述中框本体110的表面，所述第二表面1223与所述第三表面1224相对设置，且所述第二表面1223与所述第一表面1222弯折相连，所述第三表面1224与所述第一表面1222弯折相连。所述第二缝隙1221贯穿所述第一表面1222，且所述缝隙还贯穿所述第二表面1223及所述第三表面1224。
所述第一缝隙130的宽度W1为：0.8mm≤W1≤2.0mm。当所述第一缝隙130的宽度越大时，所述第一天线20及所述第二天线30的净空越大，则所述第一天线20及所述第二天线30收发电磁波信号的性能越好。相应地，所述第二缝隙1221的宽度W2为：0.8mm≤W2≤2.0mm。当所述第二缝隙1221的宽度越大时，所述第一天线20及所述第二天线30的净空越大，则所述第一天线20及所述第二天线30收发电磁波信号的性能越好。
在一实施方式中，所述第一边框121连接在所述边框120本体的周缘，且所述第一边框121凸出所述中框本体110开设所述第一缝隙130的两个表面中的至少一个表面。所述第二边框122与所述第一边框121弯折相连，所述第二边框122连接在所述边框120本体的周缘，且所述第二边框122凸出所述边框120本体开设所述第二缝隙1221的两个表面中的至少一个表面。所述第一边框121、所述第二边框122及所述中框本体110形成收容空间，以收容电子设备1中的器件。在本实施例的示意图中，以所述第一边框121及所述第二边框122均凸出所述中框本体110开设所述第一缝隙130的两个表面为例进行示意。
下面对第一枝节210及所述第二枝节310的划分进行详细说明。所述第一缝隙130包括背离所述第二边框122的一端以及背离所述第一边框121的一端。为了方便命名，所述第一缝隙130背离所述第二边框122的一端命名为第一端，所述第一缝隙130背离所述第一边框121的一端命名为第二端。由于所述第一边框121对应第一端处的部位与所述中框本体110是连接在一起的，因此，所述第一边框121连接所述中框本体110的部位可被视为是第一枝节210的接地端。因此，所述第一边框121对应所述第一缝隙130的部位、以及所述第二边框122连接于所述第一边框121的部是第一枝节210。由于所述第二边框122对应所述第二端处的部位与所述中框本体110是连接在一起的，因此，所述第二边框122连接所述中框本体110的部位可被视为是第二枝节310的接地端。因此，所述第二边框122未连接所述第一边框121且对应所述第一缝隙130的部位是第二枝节310。
当所述第一天线20为接收天线时，所述第一枝节210为所述第一天线20接收电磁波信号的部件，换而言之，所述第一天线20通过第一枝节210接收电磁波信号；当所述第一天线20为发射天线时，所述第一枝节210为第一天线20辐射电磁波信号的部件，换而言之，所述第一天线20通过所述第一枝节210发射电磁波信号。相应地，当所述第二天线30为接收天线时，第二枝节310为所述第二天线30接收电磁波信号的部件，换而言之，所述第二天线30通过第二枝节310接收电磁波信号；当所述第二天线30为发射天线时，所述第二枝节310为第二天线30辐射电磁波信号的部件，换而言之，所述第二天线30通过所述第二枝节310发射电磁波信号。
在一实施例中，所述第一缝隙130中不做任何填充。可以理解地，在另一实施例中，所述第一缝隙130中填充有非电磁波屏蔽介质，所述非电磁波屏蔽介质可以为但不仅限于为塑胶。相较于所述第一缝隙130中未填充非电磁波屏蔽介质的中框10而言，所述第一缝隙130中填充有非电磁波屏蔽介质时所述中框10的结构强度较大。
在一实施方式中，所述第二缝隙1221不做任何填充。可以理解地，在一实施例中所述第二缝隙1221中也填充有非电磁波屏蔽介质。相较于所述第二缝隙1221中未填充非电磁波屏蔽介质的中框10而言， 所述第二缝隙1221中填充有非电磁波屏蔽介质时的所述中框10的结构强度较大。当所述边框120背离所述中框本体110的表面构成所述电子设备1的部分外观面时，所述第二缝隙1221中填充有非电磁波屏蔽介质可增强所述电子设备1的防尘防水性能。
本申请实施例提供的电子设备1将第一天线20的第一枝节210及第二天线30的第二枝节310通过第二边框122上的同一个缝隙(第二缝隙1221)分割，同时通过隔离电路320隔离第一天线20对第二天线30的干扰，从而保证即便所述第一天线20的第一枝节210与所述第二天线30的第二枝节310仅仅通过较少的缝隙分割开时，第一天线20及第二天线30仍然能够正常工作。所述隔离电路320的设置可隔离所述第一天线20及所述第二天线30，有利于提升第二天线30的通信性能。此外，本申请实施例中的电子设备1中所述中框10的边框120上的缝隙的数目较少，一方面有利于提升所述中框10的结构强度，另一方面可节约加工时间，再者当所述边框120背离所述中框本体110的表面作为电子设备1的部分外观面时可使得电子设备1的外观完整性较好。

下面对第一天线20及第二天线30的隔离度进行仿真分析，请参阅图10，图10为本申请第一天线及第二天线的隔离度的仿真图。在本仿真图中横坐标为频率，单位为GHz，纵坐标为隔离度，单位为dB。在本示意图中，横轴数值越小则表明所述第一天线20及所述第二天线30的隔离度越好；横轴数值越大则表明所述第一天线20及所述第二天线30的隔离度越不好。在本示意图中，点3处的增益最大，为-12.331dB，由此可见，所述第一天线20及所述第二天线30的隔离度均小于-12dB，第一天线20及所述第二天线30之间的隔离度较高，所述第一天线20对所述第二天线30的影响较小，相应地，所述第一天线20对所述第二天线30的影响较小。
下面对第一天线20的辐射效率进行仿真分析，请参阅图11，图11为本申请第一天线的辐射效率示意图。在本仿真图中横坐标为频率，单位为GHz，纵坐标为效率，单位为dB。本示意图中，增益越大则表明所述第一天线20的辐射效率越大，增益越小则表明第一天线20的辐射效率越低。点1为GPS L1频段的辐射效率，点2为WIFI 2.4G频段的辐射效率，点3为WIFI 5.2G频段及WIFI 5.8G频段的辐射效率。点1、点2及点3处的增益均大于-5dB，由此可见，所述第一天线20在点1、点2、及点3处具有较高的辐射效率。由此可见，本申请的第一天线20具有较好的通信效果。
下面对对第二天线30的辐射效率进行仿真分析，请参阅图12，图12为本申请第二天线的辐射效率示意图。在本仿真图中横坐标为频率，单位为GHz，纵坐标为辐射效率，单位为dB。本示意图中，增益越大则表明所述第二天线30的辐射效率越大，增益越小则表明第二天线30的辐射效率越低。点1为GPS L5频段的的辐射效率，点1处的增益大于-5dB，由此可见，第二天线30在点1处具有较高的辐射效率。由此可见，本申请的第二天线30具有较好的通信效果。
可以理解地，虽然本申请前述各个实施例中所述电子设备1包括所述中框10，且以所述第一天线20的第一枝节210及所述第二天线30中第二枝节310形成在所述中框10上为例进行示意.但是上述实施例不应当理解为对本申请的限定。所述第一天线20的第一枝节210及所述第二天线30中的第二枝节310也可以形成在其他部件上，比如，当所述电子1包括可导电的电池盖40(比如，金属电池盖)时，所述第一天线20及所述第二天线30的第一枝节210也可以形成在所述电池盖40上。可导电的电池盖40及中框10仅仅是电子设备1的壳体的一种具体形式。当然，所述壳体也并不局限于所述电子设备1中的可导电的电池盖40及中框10，只要所述壳体能够形成第一天线20的第一枝节210及所述第二天线30的第二枝节310即可。
当所述第一天线20的第一枝节210及所述第二天线30的第一枝节310形成的壳体为所述电子设备1中的可导电的电池盖40时，和所述第一天线20的第一枝节210及所述第二天线30的第二枝节310形成的壳体为中框10的情况一致。下面结合图13-图15进行说明，具体地，请一并参阅图13、图14及图15，图13为本申请一实施例提供的电子设备的背面示意图；图14为本申请电子设备中的电池盖自内表面的示意图；图15为图13中沿着II-II线的剖面示意图。所述壳体70包括本体710及连接在所述本体710周缘的边框720，所述本体710的周缘开设有贯穿所述本体710的相对的两个表面的第一缝隙 113，与所述第一缝隙113相邻的所述边框720上还开设有第二缝隙1221。所述第二缝隙1221连通所述第一缝隙113。所述第一缝隙113和所述第二缝隙1221将所述边框720分割成第一枝节210及第二枝节310。
相较于现有技术，本申请的电子设备1中利用壳体70形成第一枝节210及第二枝节310，利用第一枝节210形成第一天线20的辐射体及利用第二枝节310形成所述第二天线30的辐射体，且通过所述隔离电路320隔离第一天线20对第二天线30的干扰，实现了第一天线20及第二天线30之间的隔离。因此，本申请的电子设备1可在有限的空间内实现较多的频段覆盖，实现较大的带宽，具有较高的通信性能。
当所述壳体70为可导电的电池盖40时，所述壳体70形成收容空间，所述收容空间用于电子设备1的其他器件，比如，所述收容空间用于收容中框10、电路板60及屏幕50等部件。当然，所述收容空间收容的部件并不能构成对本申请的提供的壳体的限定。所述电路板60设置于所述中框10面对所述电池盖40的一侧，所述屏幕50设置于所述中框10所述电路板60的一侧。所述第一天线20及所述第二天线30的电路均设置于所述电路板60上。举例而言，所述第一激励源220、所述第二激励源340、及所述隔离电路320均设置于所述电路板60上。
可以理解地，当所述壳体70为可导电的电池盖40时，所述电子设备1中还包和当所述壳体70为中框10时的各个电路及子电路。各个电路请参阅前面的描述，在此不再赘述。当所述壳体70为可导电的电池盖40时，所述第一缝隙113及所述第二缝隙1221相较于所述壳体70的其他部件的关系如当壳体70为中框10时的实施方式一样，在此不再赘述。
可以理解地，在本申请的背景技术具体实施方式中以所述第一天线20工作在第一频段，所述第一频段包括GPS L1频段、WIFI 2.4G频段、WIFI 5.2G频段、及WIFI 5.8G频段，且以所述第二天线30工作在第二频段，所述第二频段包括GPS L5频段为例进行说明，所述第一天线20及所述第二天线30的介绍并不能理解为对本申请第一天线20及第二天线30的限定，在其他实施方式中，所述第一天线20及所述第二天线30还可以为支持其他的频段的天线。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型，这些改进和润饰也视为本申请的保护范围。
