由于HB频段对天线空间要求相对较低，现有中一般是将支持HB频段的天线体设置于电子设备100的内部，以尽量减少天线性能的影响。本申请中，通过在支持MHB频段的第一天线体ANT1上进一步整合至少一个HB频段的收发功能而支持MHB频段和所述至少一个HB频段，在金属边框10实现对至少一个HB频段的支持，提高了天线性能，且无需在电子设备100的内部设置该些支持HB频段的天线体，降低了成本，此外，也无论电子设备100的后盖是否为金属后盖、印刷有电路板的后盖或者具有电致变色功能的后盖，都不会影响HB频段等天线频段的收发性能。

即，本申请中，所述第二天线体ANT2上还通过第二匹配电路15滤除了MHB频段以及5G N78及N79频段、WIFI 5G频段等HB频段的信号，因此，即使所述第一天线体ANT1和所述第二天线体ANT2相邻设置，也不会发生信号干扰，从而，实现了第一天线体ANT1和第二天线体ANT1之间的隔离。

其中，如前所述的，所述第一天线体ANT1和所述第二天线体ANT2相邻设置，且通过缝隙11隔离，所述第一天线体ANT1和所述第二天线体ANT2实际上是共口径/缝隙的天线，所述第一天线ANT1还能通过所述缝隙11耦合到第二天线体ANT2，并通过所述至少一个开关单元16接地，而形成经过所述缝隙11以及所述至少一个开关单元16的馈电路径。而所述第二天线体ANT2也能形成从第二天线体ANT2的馈电点F2到所述至少一个开关单元16，然后到地的馈电路径。因此，当控制所述至少一个开关单元16的不同匹配元件支路中的开关的通断而选择不同的匹配元件支路工作，将同时对所述第一天 线体ANT1和所述第二天线体ANT2的谐振频率产生影响，从而改变所述第一天线体ANT1和所述第二天线体ANT2支持的频段。如此，通过控制不同匹配元件支路中的开关的通断，使得第一天线体ANT1和第二天线体ANT2可根据需要工作在不同的频段中，而可拓宽所述第一天线体ANT1和第二天线体ANT2的频宽。

其中，所述第二匹配电感L12与所述第三匹配电感L13的电感值不同，所述第四匹配电容C14和所述第五匹配电容C15的电容值不同。从而，当不同的匹配支路导通或者不同组合的匹配支路导通时，产生不同的匹配参数，而实现不同频段的谐振匹配。
在一些实施例中，所述第二匹配电感L12的电感值为24NH，所述第三匹配电感L13的电感值为15NH，所述第四匹配电容C14的电容值为0.3PF，所述第五匹配电容C15的电容值为3PF。

其中，所述两个短边框101包括第一短边框101a以及第二短边框101b，所述两个长边框102包括第一长边框102a以及第二长边框102b。所述第一短边框101a位于电子设备100的底部，所述第二短边框101b位于电子设备100的顶部，所述第一长边框102a位于电子设备100的左侧，所述第二长边框102b位于电子设备100的右侧。其中，所述金属边框10设有的至少一个缝隙11至少包括在第一短边框101a上开设的第一缝隙11a，所述第一长边框102a中的特定位置接地而形成第一接地点G1，所述第二长边框102b中的特定位置接地而形成第二接地点G2；所述第一缝隙11和所述第一接地点G1之间的边框部分构成所述第二天线体ANT1，所述第一缝隙11和所述第二接地点G2之间的边框部分构成所述第二天线体ANT2。
其中，所述第一长边框102a中接地而形成第一接地点G1的特定位置可为所述第一长边框102a上靠近所述第一短边框101b的位置，所述第二长边框102b中接地而形成第一接地点G2的特定位置也均可为所述第二长边框102b上靠近所述第一短边框101b的位置。
其中，图1为从电子设备100的屏幕一侧进行观看的示意图，所述方位名词“顶部”、“底部”、“左侧”、“右侧”均为从图1视角观看的方位。
其中，所述第一短边框101a上开设有USB接口等连接接口J1。即，所述第一短边框101a为开设有USB接口的边框。
本申请中，所述电子设备100的底部具体可为开设有USB接口等连接接口一端。
从而，在图1所示的实施例中，通过一个缝隙11使得所述金属边框10形成一个边框段时，能够形成所述第一天线体ANT1以及所述第二天线体ANT2。
请参阅图9，为本申请另一实施例中的电子设备100的示意出部分内部结构的平面示意图。如图9所示，所述至少一个缝隙11除了包括在第一短边框101a上开设的第一缝隙11a，还包括在所述第一长边框上开设的第二缝隙11b以及在所述第二长边框上开设的第三缝隙11c，所述第一缝隙11a、第二缝隙11b以及第三缝隙11c至少将所述金属边框10分隔成位于所述第一缝隙11a以及第二缝隙11b之间的第一边框段10a以及位于所述第一缝隙11a和第三缝隙11c之间的第二边框段10b，其中，所述第一边框段10a在位于所述第一长边框102a中的特定位置接地而形成所述第一接地点G1，所述第一边框段10a的位于所述第一缝隙11和所述第一接地点G1之间的部分构成所述第一天线体ANT1；所述第二边框段10b在位于所述第二长边框102b中的特定位置接地而形成所述第二接地点G2，所述第二边框段10b的位于所述第一缝隙11a和所述第二接地点G2之间的部分构成所述第二天线体ANT2。
显然，所述金属边框10还可开设更多的缝隙11，而隔离出更多的边框段，而形成支持更多频段的天线体，例如，如图9所示，所述第二短边框101b上还可设置第四缝隙11d以及第五缝隙11e，而隔离出更多的边框段，通过将该些边框段与不同频段的馈源连接，而可支持相应频段的射频信号的收发。由于与本发明改进无关，故不再进行赘述。
从而，通过一个缝隙11使得所述金属边框10形成多个边框段时，通过该多个边框段也能够形成所述第一天线体ANT1以及所述第二天线体ANT2。
请参阅图10，为本申请一实施例中的电子设备100的后视图，如图10所示，所述电子设备100包括后盖20，其中，所述后盖20的至少部分区域为电致变色区域或者至少部分区域为金属制成。例如，所述后盖20的中间区域为电致变色区域，或者为金属制成。其中，所述电致变色区域中可设置有电致变色材料，所述电致变色区域能够电场的作用下发生颜色的变化，例如，所述电致变色区域位于两个电极片中间，当通过两个电极片施加电场时，所述电致变色区域可变为透明，当未施加电场时，所述电致变色区域变为不透明且呈现特定颜色。

其中，本申请中，所述词语“连接”包括了直接连接和间接连接，例如，A与B连接，包括了A与B直接连接的方式，也包括了A通过C与B连接的间接连接方式。
其中，所述电子设备100还包括前壳，所述前壳用于对电子设备100的显示屏等进行支撑，并用于提供整机地。前述的接地均可以理解为与所述前壳电接触，而实现接地。
其中，所述电子设备100还包括主板，前述的所有的馈源、匹配电路以及开关单元等均可设置于主板上。其中，主板上的地与所述前壳连接，而形成共同的地。
其中，所述电子设备100还包括其他元件，例如存储器等等，由于与本发明改进无关，故不再赘述。
本发明实施例所涉及到的电子设备可以包括各种具有天线的手机、平板电脑等手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)等等。为方便描述，上面提到的设备统称为天线设备。
从而，本申请中，通过在支持MHB频段的第一天线体ANT1上进一步整合至少一个HB频段的收发功能而支持MHB频段和所述至少一个HB频段，在金属边框10实现对至少一个HB频段的支持，提高了天线性能，且无需在电子设备100的内部设置该些支持HB频段的天线体，降低了成本，此外，也无论后盖是否为金属后盖、印刷有电路板的后盖或者具有电致变色功能的后盖，都不会影响至少一个HB频段等天线频段的性能。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上对本发明实施例进行了详细介绍，本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方 法及其核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本发明的限制。
