可以理解的是，第一谐振对应的第一频段可以是超高频频段(Ultra High Band，简称UHB，包括3000MHz-6000MHz频段范围)。例如但不限于第一频段可以是5G的N77频段、N78频段；当然，通过调节第一导体段Z1、第二导体段Z2的枝节长度、电连接的匹配电路的阻抗，也可以使得第一频段为其他的超高频频段，本申请实施例对第一频段不进行具体的限定。
其中，当第一匹配电路181对第一激励电流I1等效短路使得第一激励电流I1直接接地时，第一激励电流I1也可以至少分布于第一馈电点113和第二端112之间、以及第三端121和电连接点124之间，并且，第一激励电流I1在第一辐射体110上的流向可以与第一激励电流I1在第二辐射体120上的流向不同。
例如，请结合图1至图3并请参考图4，图4为图1所示的天线装置100的第二种电流示意图，第一激励电流I1可以经第一馈源171流动至第一辐射体110，并可以经第一耦合间隙101耦合(即电磁耦合)至第二辐射体120上，第一激励电流I1在第一辐射体110的第一导体段Z1上的流向可以与在第二辐射体120的第二导体段Z2上的流向相反，例如但不限于第一激励电流I1在第一导体段Z1上可以从第一馈电点113流向第二端112、在第二导体段Z2上可以从电连接点124流向第三端121，第一激励电流I1可以激励第一导体段Z1和第二导体段Z2共同工作于第二谐振并支持第二频段。

可以理解的是，第二谐振对应的第二频段可以不完全与第一谐振对应的第一频段相同，二者可以存在部分重叠的频段。例如，第一谐振对应的第一频段可以是N78频段(3300MHz-3800MHz)，第二谐振对应的第二频段可以是N77频段(3300MHz-4200MHz)。当然，通过对第一导体段Z1、第二导体段Z2电长度的调节，也可使得第二频段完全不同于 第一频段。本申请实施例对第一频段和第二频段的具体范围不进行限定。
可以理解的是，由于激励电流为交流信号，其电流方向会周期性变化，因此，当第一导体段Z1和第二导体段Z2共同工作于第一谐振时，第一激励电流I1可以在第一枝节Z1上从第二端112流向第一馈电点113、在第二枝节Z2上从电连接点124流向第三端121；当第一导体段Z1和第二导体段Z2共同工作于第二谐振时，第一激励电流I1可以在第一枝节Z1上从第二端112流向第一馈电点113、在第二枝节Z2上可以从第三端121流向电连接点124。需要说明的是，本申请后文中的其他激励电流例如第二激励电流I2、第三激励电流I3、第四激励电流I4……均具有该特性，也就是说，后文中激励电流的流向既可以如本申请实施例中的说明，也可以是该说明的反方向，后文中不再对激励电流的流向进行解释说明。
可以理解的是，本申请实施例对第一激励电流I1的说明，是对大部分(主要的)的第一激励电流I1的说明，也即，上述第一激励电流I1在第一导体段Z1、第二导体段Z2上的流动，是指大部分(主要的)的第一激励电流I1在第一导体段Z1、第二导体段Z2上流动。后文中对其他的激励电流例如第二激励电流I2、第三激励电流I3、第四激励电流I4……的说明，也是指大部分的激励电流。后文中不再对此进行解释说明。
可以理解的是，第一导体段Z1可以四分之一波长模态、第二导体段Z2也可以四分之一波长模态共同工作于第二谐振。当然，第一导体段Z1、第二导体段Z2也可以其他模态工作于第二谐振，例如但不限于以二分之一波长模态、四分之三波长模态、八分之一波长模态等，本申请实施例对此不进行限定。
可以理解的是，第二谐振对应的第二频段可以是超高频频段。例如但不限于第二频段可以是5G的N77频段、N78频段；当然，通过调节第一导体段Z1、第二导体段Z2的枝节长度、电连接的匹配电路的阻抗，也可以使得第二频段为其他的超高频频段，本申请实施例对第二频段不进行具体的限定。
可以理解的是，第一馈源171可以提供第一激励电流I1以使天线装置100工作于第一谐振并支持第一频段信号的传输；第一馈源171也可以提供第一激励电流I1以使天线装置100工作于第二谐振并支持第二频段信号的传输；第一馈源171还可以提供第一激励电流I1，以使得天线装置100可以同时工作于第一谐振和第二谐振并同时支持第一频段和第二频段的信号。
示例性的，请参考图5，图5为图1所示的天线装置100的一种S11参数曲线示意图，图5中曲线L1为第一馈源171提供第一激励电流I1时天线装置100同时工作于第一谐振和第二谐振的S11曲线，由曲线L1可以看出，天线装置100可以产生两个谐振-第一谐振A1和第二谐振A2，并且，该两个谐振对应的频段可以共同实现国内外UHB的N77/N78宽频段覆盖要求，第一频段和第二频段可以共同覆盖3300MHz至4100MHz。
其中，如图5所示，第二谐振A2对应的第二频段可以高于第一谐振A1对应的第一频段。例如，第一谐振A1的谐振频点可以3600MHz附近，第二谐振A2的谐振频点可以在3800HMz附近，第二频段可以高于第一频段。可以理解的是，由于第二频段和第一频段是具有一定带宽的频段，第二频段和第一频段可以部分频段重合，也可以完全不重合，此处第二频段高于第一频段可以是指第二频段的中心频率高于第一频段的中心频率，并不限于整个第二频段均高于第一频段。当第一激励电流I1在第一导体段Z1和第二导体段Z2的流向相反并使得天线装置100工作于第二谐振时，第二谐振的下降沿可在第二谐振的低频处，如果第二谐振的第二频段低于第一谐振的第一频段，那么第二谐振在第一频段范围内容易形成效率凹槽，从而严重影响天线装置100的辐射性能。本申请实施例的第二频段高于第一频段，既可以拓宽天线装置100的带宽，第二频段也可以提高第一频段的效率，使得天线装置100具有更优的辐射性能。

电池600设置在中框400上，并通过后壳700将电池600密封在电子设备10的内部。同时，电池600电连接至电路板500，以实现电池600为电子设备10供电。其中，电路板500上可以设置有电源管理电路。电源管理电路用于将电池600提供的电压分配到电子设备10中的各个电子器件。
后壳700与中框400连接。例如，后壳700可以通过诸如双面胶等粘接剂贴合到中框400上以实现与中框400的连接。其中，后壳700用于与中框400、显示屏300共同将电子设备10的电子器件和功能组件密封在电子设备10内部，以对电子设备10的电子器件和功能组件形成保护作用。
其中，请结合图36并请参考图37，图37为本申请实施例提供的电子设备10的第二种结构示意图。当图36为电子设备10的正视图时，图37为电子设备10的背视图，图36中电子设备10的正面为显示屏300、背面为后壳700，图37中电子设备10的正面为后壳700、背面为显示屏300。电子设备10可以包括边框420例如长边框421。
该长边框421可以是电子设备10的一条边框420，电子设备10还可以包括与该长边框421相对设置的短边框422，短边框422的长度可以小于长边框421的长度，该短边框422可以但不限于与长边框421直接或间接连接。
天线装置100可以相对电子设备10的边框420设置，例如天线装置100的第一辐射体110和第二辐射体120可以相对电子设备10的长边框421设置。示例性的，当该长边框421为导体结构时，第一辐射体110、第二辐射体120可以通过开缝隙形成辐射枝节的形式形成于长边框421上(此时，第一辐射体110、第二辐射体120的投影位于长边框421上)；再例如，第一辐射体110、第二辐射体120还可以直接或间接连接于长边框421上且第一辐射体110和第二辐射体120的投影可位于长边框421上；又例如，第一辐射体110和第二辐射体120可以与长边框421间隔设置但第一辐射体110和第二辐射体120的投影位于长边框421上。本申请实施例对第一辐射体110、第二辐射体120与长边框421的具体结构不进行限定。
可以理解的是，电子设备10可以具有横屏手握场景和竖屏手握场景。竖屏手握场景是指用户将电子设备10竖向放置使得电子设备10的短边框422处于电子设备10的顶部或者底部(可如图37所示，图37中示意出电子设备10处于竖屏状态的示意图)，此时用户握持电子设备10时往往覆盖电子设备10底部的短边框422。请结合图37并请参考图38，图38为图37所示的电子设备10的一种应用场景图。图38中电子设备10的正面为显示屏、背面为后壳700，电子设备 10的左部为竖屏状态时显示屏300的上半部分，电子设备10的左部为竖屏状态下显示屏300的下半部分。横屏手握场景是指用户将电子设备10横向放置使得电子设备10的长边框421处于电子设备10的顶部或底部，由于长边框421的长度较长，此时用户握持电子设备10时往往覆盖电子设备10底部的长边框421的部分区域，可以将用户横屏手握场景下不易覆盖的长边框421的区域作为长边框421的预设区域。
可以理解的是，电子设备10可以使得第一辐射体110和第二辐射体120相对该预设区域设置，以使得电子设备10处于横屏手握场景下，用户握持电子设备10时至少不覆盖第一耦合间隙101，从而，用户的手握行为不易影响第一激励电流I1、第一激励电流I1经第一耦合间隙101电磁耦合到第二辐射体120而工作于第一谐振、第二谐振，也不易影响第二激励电流I2经第一耦合间隙101耦合到第一辐射体110而工作于第五谐振，天线装置100及电子设备10在用户手握场景下也可以具有较优的天线性能。
示例性的，请结合图37和图38并请参考图39，图39为图38所示的电子设备10在横屏手握状态与非手握状态下支持无线信号时系统效率曲线示意图。图39中曲线L21为电子设备10在非手握状态下第一馈源171工作时的天线装置100的系统效率曲线；曲线L22为电子设备10在非手握状态下第二馈源172工作时的天线装置100的系统效率曲线；曲线L23为电子设备10在横屏手握状态下第一馈源171工作时的天线装置100的系统效率曲线；曲线L24为电子设备10在横屏手握状态下第二馈源172工作时的天线装置100的系统效率曲线。对比曲线L21和曲线L23、以及曲线L22和曲线L24可知，当电子设备10处于横屏手握场景时，天线装置100在UHB全频段以及MHB全频段降幅分别在0.9dB-2.9dB，天线装置100的性能依然可以维持在较高水平。将第一辐射体110和第二辐射体120相对长边框421设置，相比将第一辐射体110和第二辐射体120相对短边框422设置的方案而言，本申请实施例相对长边框421设置的第一辐射体110和第二辐射体120，在横屏手握场景下的天线效率降幅更小。
可以理解的是，为了进一步避免用户手握对天线装置100的影响，如图36所示，可以将第一辐射体110和第二辐射体120相对于横屏手握状态下电子设备10顶部的长边框421设置。
可以理解的是，为了进一步避免用户对天线装置100的影响，可以调整预设区域的范围，使得横屏手握场景下，用户也可以不握持第一辐射体110和第二辐射体120，以进一步降低手握对天线装置100性能的影响。当然，也可以调整预设区域的范围，使得用户可以遮挡部分或全部的第一辐射体110、第二辐射体120而不遮挡第一耦合间隙101。本申请实施例对第一辐射体110和第二辐射体120的具体设置位置不进行限定。
本申请实施例的天线装置100，第一辐射体110和第二辐射体120相对电子设备10的长边框421设置，横屏手握场景下用户不易覆盖第一耦合间隙101，用户手握对电子设备10的影响较小。
其中，请参考图40和图41，图40为本申请实施例提供的电子设备10的第三种结构示意图，图41为本申请实施例提供的电子设备10的第四种结构示意图。图40、图41中电子设备10的正面为后壳700、背面为显示屏300。电子设备10可以包括相互弯折连接的长边框421和短边框422。
第一辐射体110和第二辐射体120可以相对长边框421设置；部分第三辐射体130可以相对长边框421设置、另一部分第三辐射体130可以相对短边框422设置，第四辐射体140可以相对短边框422设置；从而，第一辐射体110和第二辐射体120组成的MHB+UHB的游戏天线群可以相对长边框421设置；第三辐射体130和第四辐射体140组成的GPS+Wi-Fi2.4G/5G+UHB天线群可以相对电子设备10的拐角设置；第二辐射体120和第三辐射体130之间的导体连接段150相对长边框421设置，可以复用为电子设备10的按键结构。
可以理解的是，电子设备10可以包括上述第一辐射体110、第二辐射体120、第三辐射体130、第四辐射体140和导体连接段150中的一个或多个(两个及以上)的上述设置方案，本申请实施例对此不进行详细说明。
可以理解的是，上述辐射体相对长/短边框422设置，既可以是指辐射体形成于导体结构的长/短边框422上，也可以是指辐射体直接或间接连接于长/短边框422上且投影于长/短边框422上，还可以是指辐射体与长/短边框422间隔设置但投影于长/短边框422上。本申请实施例对上述辐射体的具体设置位置不进行限定。
本申请实施例的天线装置100及电子设备10，第一辐射体110和第二辐射体120可以形成口径天线并实现无开关覆盖MHB+UHB频段的宽频游戏天线，一方面，第一辐射体110和第二辐射体120使用共口径模态可以满足国内外UHB-N77/N78宽频段(3300MHz-4100MHz)覆盖要求；另一方面，共口径模态空间利用率高，有利于整机更好地堆叠；又一方面，天线装置100不需要开关切换即可实现宽频段覆盖，有效节省电子设备10内部空间，减少整体成本；同时，第一辐射体110和第二辐射体120相对长边框421设置，横屏双手玩游戏场景下天线装置100的辐射性能依然较高，可以实现游戏不卡顿。
其中，请结合图33、图40和图41，天线装置100的导体连接段150可以接收用户的按压操作，导体连接段150可以作为电子设备10的按键结构，例如但不限于导体连接段150可以作为设备的音量按键、电源按键、开关控制按键等。当导体连接段150作为按键结构时，导体连接段150可以裸露在天线装置100或电子设备10的外部，以接收用户的按压操作。
可以理解的是，导体连接段150的长度可以根据按键结构的大小进行适应性调整。本申请实施例对此不进行限定。
其中，请结合图34、图40和图41，Sar传感器200可以是天线装置100或者电子设备10的一个部件，也可以是其他设备的部件。Sar传感器200可以提供检测信号，该检测信号可以在第二辐射体120、导体连接段150和第三辐射体130共同形成的感应枝节上流动，当人体靠近时，检测信号会产生一定的变化，Sar传感器200可以通过检测信号发生的变化判断人头/手是否靠近或远离，以判断电子设备10的Sar值的大小。
可以理解的是，天线设计中，往往通过Sar指标来评价电子设备10产生的电磁辐射对人体的影响。Sar值越大，表示对人体的影响越大。本申请实施例中，Sar传感器200利用感应枝节进行Sar值大小的判断，感应枝节和人体部分(如手)形成等效电容器，二者之间有等效电容，距离减少的话电容增加，反之降低：当用户未靠近感应枝节时，Sar传感器200可以判断检测信号可处于预设范围内；当用户靠近感应枝节时，Sar传感器200检测的检测信号的数据可以发生显著变化；通过该变化，Sar传感器200可以判断用户是否靠近或远离，也可以判断出天线装置100的Sar值是否超过规定的Sar值阈值，以便于电子设备10可以根据Sar值来调整多个谐振的发射功率或者执行功率回退事件。
需要说明的是，第二辐射体120、导体连接段150和第三辐射体130共同形成整体并不局限于复用为按键或Sar传感器200的感应枝节，例如但不限于三者形成整体可以增加天线装置100的结构强度。本申请实施例对此不进行限定。
需要说明的是，本申请实施例第一辐射体110、第二辐射体120、第三辐射体130、第四辐射体140中的一个、两个、三个或四个也可以复用为Sar传感器200的感应枝节，例如但不限于在第一辐射体110的第一端111和接地平面之间串联一通直流阻交流的第八匹配电路，或者，在第四辐射体140的第八端142和接地平面之间串联另一通直流阻交流的第九匹配电路。可以理解的是，天线装置100可以包括第六匹配电路186、第七匹配电路187、第八匹配电路、第九匹配电路中的至少一个，以使得第一辐射体110、第二辐射体120、第三辐射体130、第四辐射体140中至少一个处于“悬浮”状态。当然，如果相邻两个辐射体之间通过导体件连接为整体时，此时需要设置多个匹配电路以使得整个枝节均处于“悬浮”状态。本申请实施例对此不进行具体的限定。
本申请实施例的天线装置100及电子设备10，第二辐射体120、导体连接段150和第三辐射体130共同形成Sar传感器200的感应枝节，整个感应枝节可处于悬浮状态而检测人/手靠近天线装置100或电子设备10的不同距离来回退不同功率值，提升用户体验；并且，第六匹配电路186和第七匹配电路187采用大电容回地，使得该匹配电路对第三辐射体130和第四辐射体140支持的无线信号的频段影响不大，避免增加天线调试的难度。同时，导体连接段150可以复用为电子设备10的音量或开关按键，通过同一种天线方案设计，兼顾不同的ID外观需求，可以满足不同电子设备10的兼容性需求，将导体连接段150复用为按键，对天线装置100的影响不大。
本申请实施例的天线装置100及电子设备10，第三辐射体130和第四辐射体140形成口径天线并可以支持GPS+Wi-Fi2.4G/5G+UHB，可以实现短距离的覆盖。并且，整个天线装置100可以实现MHB+UHB+GPS+Wi-Fi2.4G+Wi-Fi5G的多频段广覆性能，在不增加开关成本的前提下展宽了天线带宽。并且，本申请实施例的天线装置100通过不同匹配电路，可以实现各频段的高隔离度需求，进一步提高个频段的辐射性能。
可以理解的是，以上仅为电子设备10的示例性举例，本申请实施例的电子设备10还可以包括摄像头、传感器、声电转换装置等部件，这些部件可以参见相关技术中的描述，在此不再赘述。
需要说明的是，以上实施例在不冲突的前提下可以任意进行组合，组合后的实施例方案依然在本申请实施例的保护范围内。需要理解的是，在本申请的描述中，诸如“第一”、“第二”等术语仅用于区分类似的对象，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。
以上对本申请实施例提供的天线装置及电子设备进行了详细介绍。本文中应用了具体个例对本申请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申请。同时，对于本领域的技术人员，依据本申请的思想，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申请的限制。
