结合上述描述，下面对本申请实施例的天线组件进行具体介绍。
请参阅图4，图4是本申请实施例提供的一种天线组件的结构示意图。天线400可以应用于电子设备100。天线组件400可以包括第一天线、第二天线、天线连接体431、第一匹配电路432和第二匹配电路433。其中，第一天线可以包括第一天线辐射体411和第二天线辐射体412，第一天线辐射体411和第二天线辐射体412之间存在第一缝隙413；
第二天线可以包括第三天线辐射体421；
第一天线辐射体411可以包括第一耦合端(C)和第一接地端(B)，第二天线辐射体包括第二耦合端(D)和第二接地端(E)，第一耦合端(C)和第二耦合端(D)分别位于第一缝隙413两侧并通过第一缝隙413耦合，第一接地端(B)设有第一接地点(GND1)，第二接地端(E)设有第二接地点(GND2)，第一天线辐射体411通过第一接地端(B)连接第一匹配电路432以接地系统；
第三天线辐射体421可以包括第一自由端(G)和第三接地端(H)，第三接地端(H)设有第三接地点(GND3)，第三天线辐射体421通过第三接地端(H)连接第二匹配电路433以接地系统，天线连接体431分别连接第一接地端(B)和第三接地端(H)；
第一天线辐射体411上可以设有第一馈电点(A)，第一馈电点(A)可以用于连接第一馈源414；
第三天线辐射体421上设有第二馈电点(F)，第二馈电点(F)可以用于连接第二馈源422。
具体的，第一天线辐射体411可以为柔性电路板(Flexible Printed Circuit，FPC)天线辐射体、激光直接成型(Laser Direct Structuring，LDS)天线辐射体、印刷直接成型(Print Direct Structuring，PDS)天线辐射体、金属枝节中的任一种。同理，第二天线辐射体412可以为FPC天线辐射体、LDS天线辐射体、PDS天线辐射体、金属枝节中的任一种。
需要说明的是，在天线组件400的第一天线中，由于第一天线辐射体411和第二天线辐射体412间隔设置(即二者之间存在第一缝隙413)，即第一天线辐射体411和第二天线辐射体412共口径，因此第一缝隙413存在耦合，从而使得第一天线辐射体411和第二天线辐射体412相当于通过电容连接。其中，该电容的电容值可以由第一天线辐射体411一端(C)所在端面的相对面积、第二天线辐射体412一端(D)所在端面的相对面积、CD之间的间距和第一缝隙413内填充的介质共同决定。
另外，当天线组件400工作时，第一馈源414产生的激励信号可经由第一天线辐射体411耦合到第二天线辐射体412。因此，第二天线辐射体412可以通过第一缝隙413的耦合产生第一天线的多个谐振模态。可见，在第一天线收发电磁波信号时，不仅可以利用第一天线辐射体411，还可以利用第二天线辐射体412，从而实现天线组件400的天线通信性能。同时，通过一个缝隙(第一缝隙)增加天线组件400的谐振模态，从而实现天线组件400覆盖多个频段，保证天线组件400支持多载波聚合的传输需求，以及提升空间复用能力。
具体的，第三天线辐射体421可以为FPC天线辐射体、LDS天线辐射体、PDS天线辐射体、金属枝节中的任一种。
需要说明的是，在天线组件400的第二天线中，第二馈源422可以用于产生激励信号，并由激励信号加载在第三天线辐射体421，以使得第三天线辐射体421辐射电磁波信号。由于第三天线辐射体421上的FH段可以等效于到地小电感，因此第三天线辐射体421上的FG段可以通过第二馈源422的激励产生谐振模态。同理，第三天线辐射体421上的GH段可以通过第二馈源422的激励产生谐振模态。因此，第三天线辐射体421可以通过第二馈源422的激励产生第二天线的多个谐振模态。
可见，通过在天线组件400中的第二天线，从而增加天线组件400的谐振模态，实现天线组件400覆盖多个频段，保证天线组件400支持多载波聚合的传输需求，以及提升空间复用能力。
具体的，天线连接体431可以用于连接第一天线和第二天线。
需要说明的是，本申请实施例通过天线连接体431连接第一天线和第二天线，从而实现第一天线和第二天线的共辐射体。因此，当第一天线工作时，不但可以利用自身的第一天线辐射体411和第二天线辐射体412来收发电磁波信号，还可以利用第二天线的第三天线辐射体421，以及新增的天线连接体431来收发电磁波信号，从而提高天线组件400覆盖的频段，保证天线组件400支持多载波聚合的传输需求，以及提升空间复用能力。同理，当第二天线工作时，不但可以利用自身的第三天线辐射体421来收发电磁波信号，还可以利用第一天线的第一天线辐射体411和第二天线辐射体412，以及新增的天线连接体431来收发电磁波信号，从而提高天线组件400覆盖的频段，保证天线组件400支持多载波聚合的传输需求，以及提升空间复用能力。
另外，通过天线连接体431将第一天线和第二天线连接，本申请实施例可以将第二天线辐射体412看作天线单元1，而将第一天线辐射体411、第三天线辐射体421和天线连接体431看作天线单元2。因此， 第一馈源414通过连接天线单元2的第一馈电点(A)，第二馈源422连接天线单元2的第二馈电点(F)，天线单元2在第一接地端(B)和第三接地端(H)分别通过第一匹配电路432和第二匹配电路433下地，从而有利于提高天线组件400的辐射效率。
具体的，天线连接体431可以与第一天线辐射体411或者第三天线辐射体421具有相同的材质。
具体的，天线连接体431可以为FPC天线辐射体、LDS天线辐射体、PDS天线辐射体、金属枝节中的任一种。
具体的，第一天线辐射体411、第二天线辐射体412、第三天线辐射体421和天线连接体431可以共面。
例如，若第一天线辐射体411、第二天线辐射体412、第三天线辐射体421和天线连接体431均为金属贴片等，则第一天线辐射体411、第二天线辐射体412、第三天线辐射体421和天线连接体431可以共面。
具体的，第一接地点(GND1)用于连接地系统；第二接地点(GND1)用于连接地系统；第三接地点(GND3)用于连接地系统。
具体的，地系统可以是指能够作为地极的部件，该地系统通常为较大块的金属构成。其中，本申请的地系统可以是同一个，该地系统可以包括一个或多个部件。在电子设备100中，该地系统110可以包括显示模组110中的接地部件、边框组件120、后盖组件130、主板140中的接地部件中的至少一个。
例如，边框组件120构成电子设备100的地极的部件，当电子设备100中的电子器件需要接地时，可连接边框组件120以接地系统。
具体的，第一匹配电路432可以用于阻抗匹配和/或隔直匹配。其中，第一匹配电路432可以包括电容、电感、电容与电感的组合、开关、可变电容中的至少之一。例如，请参阅图5，第一匹配电路432可以为图5中的(a)至(h)中的一种。
需要说明的是，第一匹配电路432可以包括隔直电容以实现隔直匹配。
具体的，第二匹配电路433可以用于阻抗匹配和/或隔直匹配。其中，第二匹配电路433可以包括电容、电感、电容与电感的组合、开关、可变电容中的至少之一。例如，请参阅图5，第二匹配电路433可以为图5中的(a)至(h)中的一种。
需要说明的是，第二匹配电路433可以包括隔直电容以实现隔直匹配。
具体的，第一缝隙413内可以填充非金属绝缘材料。
结合上述描述，下面本申请对天线组件400中的第一天线进行具体说明。
请参阅图6，第一天线包括第一天线辐射体411和第二天线辐射体412。
需要说明的是，在天线组件400的第一天线中，第一馈源414可以用于产生激励信号，并由激励信号加载在第一天线辐射体411，以使得第一天线辐射体411辐射电磁波信号。由于第一天线辐射体411上的AB段可以等效于到地小电感，因此第一天线辐射体411上的AC段可以通过第一馈源414的激励产生谐振模态。同理，第一天线辐射体411上的CB段可以通过第一馈源414的激励产生谐振模态。可见，第一天线辐射体411可以用于通过第一馈源414的激励产生第一天线的多个谐振模态。
具体的，第一天线辐射体411可以用于产生低频和高频的谐振模态，第二天线辐射体412可以用于产生中频的谐振模态。
具体的，第一天线可以用于覆盖以下至少一种频段：LTE MHB频段、LTE UHB频段、NR MHB频段、NR UHB频段、WIFI 2.4GHz频段。
可见，本申请实施例的第一天线可以覆盖LTE MHB频段、LTE UHB频段、NR MHB频段、NR UHB频段、WIFI 2.4GHz频段等，从而在满足天线通信性能的同时，实现由天线组件的第一天线覆盖多个频段，以及支持多载波聚合的传输需求。
具体的，第一天线辐射体411的长度可以大于第二天线辐射体412的长度。
具体的，第一馈电点(A)到第一耦合端(C)的长度(AC段的长度)可以大于第一馈电点(A)到第一接地端(B)的长度(AB段的长度)。
需要说明的是，本申请实施例可以通过设置第一馈电点(A)在第一天线辐射体411上的不同位置，实现第一天线支持不同的频段。其中，第一馈电点(A)在第一天线辐射体412上的位置越靠近第一接地端(B)，即AC段的长度大于AB段的长度，从而可以提高第一天线辐射体411的辐射效率。
具体的，第一天线可以用于支持第一谐振模态、第二谐振模态、第三谐振模态、第四谐振模态；其中，第一接地端到第一耦合端的长度为第一谐振模态中心频率对应波长的1/8至1/4倍；第二接地端到第二耦合端的长度为第二谐振模态中心频率对应波长的1/4倍；第一馈电点到第一耦合端的长度为第三谐振模态中心频率对应波长的1/4倍；第一接地端到第一耦合端的长度为第四谐振模态中心频率对应波长的3/4倍。

需要说明的是，谐振模态中心频率可以适配于产生该谐振模态的天线辐射体的长度。因此，第一接地端(B)到第一耦合端(C)的长度(BC段的长度)、第二接地端(E)到第二耦合端(D)的长度(DE段的长度)、第一馈电点(A)到第一耦合端(C)的长度(AC段的长度)可以分别通过其产生的谐振模态中心频率设置。
示例性的，请参阅图7，图7提供了一种第一天线的散射(scatter，S)参数(parameter)的分布示意图。其中，参数S1,1表示第一天线的反射损失。图6中的标记1表示第一谐振模态中心频率为1.7767GHz，其对应的S参数(S1,1)为-4.5137dB。因此，第一接地端(B)到第一耦合端(C)的长度约为20mm至45mm中的一个取值。由于电磁波传输速度会受到各种传输介质的影响，因此在实际工程中第一接地端(B)到第一耦合端(C)要小于上述的取值，下述同理可知。
图7中的标记2表示第二谐振模态中心频率为2.5978GHz，其对应的S参数(S1,1)为-13.398dB。因此，第二接地端(E)到第二耦合端(D)的长度可以为28mm。
图7中的标记3表示第三谐振模态中心频率为3.4879GHz，其对应的S参数(S1,1)为-7.1213dB。因此，第一馈电点(A)到第一耦合端(C)的长度约为21mm。
图7中的标记4表示第四谐振模态中心频率为4.9369GHz，其对应的S参数(S1,1)为-16.755dB。因此，第一接地端(B)到第一耦合端(C)约为45mm。
结合上述描述，下面本申请实施例将对天线组件400中的第二天线进行具体说明。
请参阅图8，第二天线包括第三天线辐射体421。
需要说明的是，在天线组件400的第二天线中，第三天线辐射体421上的FG段可以通过第二馈源422的激励产生谐振模态。同理，第三天线辐射体421上的GH段可以通过第二馈源422的激励产生谐振模态。因此，第三天线辐射体421可以用于通过第二馈源422的激励产生第二天线的多个谐振模态。可见，通过在天线组件400中的第二天线，从而增加天线组件400的谐振模态，实现天线组件400覆盖多个频段，以及保证天线组件400支持多载波聚合的传输需求。
具体的，第二天线可以用于覆盖以下至少一种频段：LTE MHB频段、LTE UHB频段、NR MHB频段、NR UHB频段、WIFI 2.4GHz频段、GPS-L1频段。
可见，本申请实施例的第二天线可以覆盖LTE MHB频段、LTE UHB频段、NR MHB频段、NR UHB频段、WIFI 2.4GHz频段、GPS-L1频段等，从而在满足天线通信性能的同时，进一步实现天线组件400覆盖多个频段，以及保证天线组件400支持多载波聚合的传输需求。
具体的，第二馈电点(F)到第一自由端(G)的长度可以大于第二馈电点(F)到第三接地端(H)的长度。
需要说明的是，本申请实施例可以通过设置第二馈电点(F)在第三天线辐射体421上的不同位置，实现第二天线覆盖不同的频段。其中，第二馈电点(F)在第三天线辐射体421上的位置越靠近第三接地端(H)，即第二馈电点(F)到第一自由端(G)的长度大于第二馈电点(F)到第三接地端(H)的长度，从而可以提高第三天线辐射体422的辐射效率。
具体的，第二天线可以用于支持第五谐振模态、第六谐振模态；其中，第三接地端(H)到第一自由端(G)的长度可以为第五谐振模态中心频率对应波长的1/4倍；第二馈电点(F)到第一自由端(G)的长度可以为第六谐振模态中心频率对应波长的1/4倍。
进一步的，第五谐振模态中心频率可以为1.5GHz至2.0GHz中的一个频率；第六谐振模态中心频率可以为2.0GHz至3.0GHz中的一个频率。

图9中的标记2表示第六谐振模态中心频率为2.515GHz，其对应的S参数(S2,2)为-7.3044dB。因此，第二馈电点(F)到第一自由端(G)的长度约为29.8mm。

需要说明的是，第四匹配电路442可以包括隔直电容以实现隔直匹配。
结合上述描述，下面本申请实施例将对天线组件400还包括第三天线进行具体说明。
请参阅图11，天线组件400还包括：第三天线，第三天线包括第四天线辐射体451；第四天线辐射体451与第三天线辐射体421之间存在第二缝隙452；第四天线辐射体包括第二自由端(I)和第四接地端(J)，第一自由端(G)和第二自由端(I)分别位于第二缝隙(452)两侧并通过第二缝隙(452)耦合，第四接地端(J)设有第四接地点(GND1)；第四天线辐射体451上设有第三馈电点(K)，第三馈电点用于连接第三馈源。
具体的，第四接地点(GND1)用于连接地系统。
需要说明的是，在天线组件400的第三天线中，首先，第三馈源453可以用于产生激励信号，并由激励信号加载在第四天线辐射体451，以使得第四天线辐射体451辐射电磁波信号。由于第四天线辐射体451上的第三馈电点(K)到第四接地端(J)可以等效于到地小电感，因此第三馈电点(K)到第二自由端(I)可以通过第三馈源453的激励产生谐振模态。同理，第二自由端(I)到第四接地端(J)可以通过第三馈源453的激励产生谐振模态。可见，第四天线辐射体451可以用于通过第三馈源453的激励产生多个谐振模态。可见，通过在天线组件400中增加第三天线，从而增加天线组件400的谐振模态，进一步实现天线组件400覆盖多个频段，以及保证天线组件400支持多载波聚合的传输需求。
其次，由于第三天线辐射体421和第四天线辐射体451间隔设置(即二者之间存在第二缝隙445)，即第四天线辐射体451和天线单元2共口径，因此第二缝隙445存在耦合，从而使得第三天线辐射体421和第四天线辐射体451相当于通过电容连接。当第三天线工作时，不但可以利用自身的第四天线辐射体451来收发电磁波信号，还可以利用天线单元1以及天线单元2来收发电磁波信号，从而进一步提高天线组件400覆盖的频段，保证天线组件400支持多载波聚合的传输需求，以及提升空间复用能力。
最后，通过第三天线辐射体421和第四天线辐射体451间隔设置，本申请实施例可以将第四天线辐射体442看作天线单元3。因此，天线单元1和天线单元2耦合，以及天线单元2和天线单元3耦合，从而提高天线组件400覆盖的频段，保证天线组件400支持多载波聚合的传输需求，以及提升空间复用能力。
具体的，第一天线辐射体411、第二天线辐射体412、第三天线辐射体421、天线连接体431和第四天线辐射体451可以共面。
例如，若第一天线辐射体411、第二天线辐射体412、第三天线辐射体421、天线连接体431和第四天线辐射体451均为金属贴片等，则第一天线辐射体411、第二天线辐射体412、第三天线辐射体421、天线连接体431和第四天线辐射体451可以共面。
具体的，第四天线辐射体451可以为FPC天线辐射体、LDS天线辐射体、PDS天线辐射体、金属枝节中的任一种。
具体的，第三天线可以用于支持以下至少一种频段：N78频段、N79频段、WIFI 5GHz频段。
可见，本申请实施例的第三天线可以覆盖N78频段、N79频段、WIFI 5GHz频段等，从而在满足天线通信性能的同时，进一步实现天线组件400覆盖多个频段，以及保证天线组件400支持多载波聚合的传输需求。
具体的，第二自由端(I)到第三馈电点(K)的长度可以小于第三馈电点(K)到第四接地端(J)的长度。
需要说明的是，本申请实施例可以通过设置第三馈电点(K)在第四天线辐射体451上的不同位置，实现第三天线覆盖不同的频段。其中，第三馈电点(K)在第四天线辐射体451上的位置越远离第四接地端(J)，即第二自由端(I)到第三馈电点(K)的长度小于第三馈电点(K)到第四接地端(J)的长度，从而可以提高第四天线辐射体451的辐射效率。
具体的，第三天线用于支持第七谐振模态、第八谐振模态、第九谐振模态、第十谐振模态；其中，第七谐振模态的电流分布是从第三馈电点到第三接地端；第四接地端到第二自由端的长度为第八谐振模态中心频率对应波长的1/8至1/4倍；第三馈电点到第二自由端的长度为第九谐振模态中心频率对应波长的1/4倍；第三接地端到第一自由端的长度为第十谐振模态中心频率对应波长的3/4倍。
进一步的，第七谐振模态中心频率可以为3.0GHz至3.5GHz中的一个频率；第八谐振模态中心频率可以为3.5GHz至4.0GHz中的一个频率；第九谐振模态中心频率可以为5.0GHz至6.0GHz中的一个频率；第十谐振模态中心频率可以为6.0GHz至7.0GHz中的一个频率。
结合上述描述，请参阅图12，图12提供了一种第三天线的S参数的分布示意图。其中，曲线S3,3表示第三天线的反射损失。图12中的标记2表示第八谐振模态中心频率为3.8669GHz，其对应的S参数(S3,3)为-5.1333dB。因此，第二自由端(I)到第四接地端(J)的长度约为9.7mm至19.4mm中的之一。由于电磁波传输速度会受到各种传输介质的影响，因此在实际工程中第二自由端(I)到第四接地端(J)的长度要小于上述的取值，下述同理可知。图12中的标记3表示第九谐振模态中心频率为5.6098GHz，其对应的S参数(S2,2)为-10.755dB。因此，第二自由端(I)到第三馈电点(K)的长度约为13.37mm。
结合上述描述，下面本申请实施例将对天线组件400还包括第五匹配电路进行具体说明。
请参阅图13，天线组件400还包括：第五匹配电路443。
具体的，第五匹配电路443可以用于阻抗匹配和/隔直匹配。其中，第五匹配电路443可以包括电容、电感、电容与电感的组合、开关、可变电容中的至少之一。例如，请参阅图5，第五匹配电路443可以为图5中的(a)至(h)中的一种。
需要说明的是，第五匹配电路443可以包括隔直电容以实现隔直匹配。
结合上述描述，为了实现天线组件400具备电磁波能量吸收比(specific absorption rate，SAR)检测的能力，本申请实施例需要考虑第一匹配电路432、第二匹配电路433、第三匹配电路441、第四匹配电路442和第五匹配电路443是否包含隔直器件，该隔直器件可以包括隔直电容或者隔直电路。
请参阅图14，若第一匹配电路432、第二匹配电路433、第三匹配电路441、第四匹配电路442和第五匹配电路443均不包含隔直器件，则天线组件400还可以包括：第一电容(C1)、第二电容(C2)、第三电容(C3)、第四电容(C4)、第五电容(C5)、第六电容(C6)和第七电容(C7)；其中，第一电容串联于第一天线辐射体411和第一接地点所连接的地系统之间；第二电容串联于第三天线辐射体421和第三接地点所连接的地系统之间；第三电容串联于第一馈电点(A)和第一馈源414之间；第四电容串联于第二馈电点(F)和第二馈源422之间；第五电容串联于第二天线辐射体412和第二接地点所连接的地系统之间；第六电容串联于第三馈电点(K)和第三馈源453之间。
其中，第一电容(C1)、第二电容(C2)、第三电容(C3)、第四电容(C4)、第五电容(C5)、第六电容(C6)、第七电容(C7)的电容值可以为22pF，从而对天线组件400的影响较小。
需要说明的是，当天线组件400应用于电子设备时，电子设备中的接近传感器可以利用悬浮的金属体来感应使用该电子设备的用户所带来的电容信号变化，从而判断用户是否靠近或远离该电子设备。
例如，在图15的(a)中，接近传感器1510包括印刷电路板板(printed circuit board，PCB)和覆盖(overlay)板，并且接近传感器1510自身能产生电容信号(C 1)。当用户1520靠近接近传感器1510时，接近传感器1510能够感应到用户1520所带来的电容信号变化(C 2)。因此，本申请实施例通过在天线组件400中添加具备隔直功能的第一电容(C1)、第二电容(C2)、第三电容(C3)、第四电容(C4)、第五电容(C5)、第六电容(C6)、第七电容(C7)，从而实现将天线组件400进行悬浮，以便将天线组件400作为相对于馈源和/或地系统中的直流电路悬浮的金属体，进而实现天线组件400具备SAR检测的能力。
另外，可以理解的是，若第一匹配电路432、第二匹配电路433、第三匹配电路441、第四匹配电路442和第五匹配电路443中存在部分的匹配电路包含隔直器件，则该部分的匹配电路不需要再添加隔直器件。例如，如果第一匹配电路432包含隔直器件(即第一匹配电路432具有隔直匹配)，天线组件400就无需包括第一电容(C1)，以及相应的连接关系，对此不作具体限制。
结合上述描述，在天线组件400包括第一天线、第二天线和第三天线的情况下，本申请实施例再对天线组件400中各天线之间的阻抗带宽、隔离度、辐射效率(radiantefficiency)和总效率(total efficiency)等进行分析。

请参阅图17，图17提供了一种第一天线、第二天线和第三天线的辐射效率和总效率的分布示意图。 其中，曲线1711表示第一天线的辐射效率，曲线1712表示第二天线的辐射效率，曲线1713表示第三天线的辐射效率，曲线1721表示第一天线的总效率，曲线1722表示第二天线的总效率，曲线1723表示第三天线的总效率。可见，天线组件400中的各天线具有良好的效率带宽。
结合上述描述，下面本申请实施例将天线组件400还包括至少一个第六匹配电路进行具体说明。
请参阅图18和图19，天线组件400还可以包括：至少一个第六匹配电路461，第六匹配电路461的一端连接天线连接体431上的第五接地端(L)，第五接地端(L)设有第五接地点(GND5)，第五接地端(L)位于第一接地端(B)和第三接地端(H)之间，第六匹配电路461的另一端接第五接地点所连接的地系统。
需要说明的是，通过在天线组件400(天线单元2)中增加下地的第六匹配电路461，有利于提高天线组件400中各天线之间的隔离度，以及能够有效滤除天线单元2上具有低效率的谐振模态。同时，第六匹配电路461的数量越多，天线组件400中各天线之间的隔离度越好，以及更有利于滤除天线单元2上具有低效率的谐振模态。
具体的，第六匹配电路461可以用于阻抗匹配和/或隔直匹配。其中，第六匹配电路461可以包括电容、电感、电容与电感的组合、开关、可变电容中的至少之一。例如，请参阅图5，第六匹配电路461可以为图5中的(a)至(h)中的一种。
需要说明的是，第六匹配电路461可以包括隔直电容以实现隔直匹配。
结合上述描述，为了实现包含第六匹配电路的天线组件400具备SAR检测的能力。因此，若第六匹配电路不包含隔直器件，则天线组件400还包括：第八电容(C8)，第八隔电容串联于天线连接体431和第五接地点所连接的地系统之间。其中，第八电容(C8)的电容值可以为22pF，从而对天线组件400的影响较小。另外，本领域技术人员结合上述描述，可知具体的连接关系，对此不再赘述。
结合上述描述，下面本申请实施例对天线组件400包括第五天线辐射体进行具体说明。
请参阅图20、图21、图22、图23和图24，天线组件400还可以包括：第五天线辐射体471，第五天线辐射体的一端(M)连接第一馈源414，第五天线辐射体的另一端(N)为开路端。

另外，本申请实施例可以将第五天线辐射体471看作天线单元4。
下面对第五天线辐射体471、第三匹配电路441和第一天线之间的连接关系做一个示例性说明。
示例性的，请参阅图25，第三匹配电路441包括第九电容(C9)、第十电容(C10)、第十一电容(C11)、第十二电容(C12)、第一电感(L1)和第二电感(L2)。其中，第九电容的容值为1.0pF，第十电容的容值为0.8pF，第十一电容的容值为0.5pF，第十二电容的容值为0.8pF，第一电感的电感值为1.0nH，第一电感的电感值为15nH。由于第五天线辐射体4711连接在0.5pF与0.8pF之间，因此，该形式的电容连接方式对天线组件400所覆盖的其他频段影响较小，对其他频段相当于并联了0.35pF(0.5pF串联0.8pF等效为0.35pF)。
具体的，第五天线辐射体471可以为FPC天线辐射体、LDS天线辐射体、PDS天线辐射体、金属枝节。
具体的，第五天线辐射体471可以用于覆盖以下至少一种频段：LTE MHB频段、LTE UHB频段、NR MHB频段、NR UHB频段、WIFI 2.4GHz频段。
具体的，第五天线辐射体471可以用于支持第十一谐振模态；第五天线辐射体471的长度(MN段的长度)可以为第十一谐振模态中心频率对应波长的1/8至1/2倍。
其中，第十一谐振模态中心频率可以为4.5GHz至5.5GHz中的一个频率。
结合上述描述，请参阅图26，图26提供了一种包括第五天线辐射体的第一天线的S参数的分布示意图。其中，曲线S1,1表示第一天线的反射损失。图26中的标记4表示第十一谐振模态中心频率为4.9793GHz，其对应的S参数(S1,1)为-13.045dB。因此，第五天线辐射体471的长度(MN段的长度)约为7.53mm至30.12mm中的之一。由于电磁波传输速度会受到各种传输介质的影响，因此在实际工程中第五天线辐射体471的长度要小于上述的取值。另外，相比于图5所示，第一天线新增的第五天线辐射体已影响图7所述的第一天线的所覆盖的频率。
结合上述描述，在天线组件400包括第五天线辐射体471的情况下，本申请实施例再对第一天线的辐射效率(radiantefficiency)和总效率(total efficiency)等进行分析。
请参阅图27，图27提供了一种第一天线的辐射效率和总效率的分布示意图。其中，曲线2711表示第一天线的辐射效率，曲线2712表示第一天线的总效率。可见，在第一天线中增加第五天线辐射体471，有利于提升天线组件的天线效率，保证天线组件具体良好的效率带宽。

第一天线辐射体上设有第一馈电点，第一馈电点用于连接第一馈源。
需要说明的是，首先，本申请对各个实施例的描述都各有侧重。因此，电子设备侧的实施例中没有详述的部分，可以参见上述天线组件400侧的实施例中的相关描述，并能达到相同的技术效果，对此不再赘述。
其次，在天线组件的第一天线中，由于第一天线辐射体和第二天线辐射体间隔设置(即二者之间存在第一缝隙)，即第一天线辐射体和第二天线辐射体共口径，因此第一缝隙存在耦合，从而使得第一天线辐射体和第二天线辐射体相当于通过电容连接。其中，该电容的电容值可以由第一天线辐射体一端所在端面的相对面积、第二天线辐射体一端所在端面的相对面积、第一缝隙之间的间距和第一缝隙内填充的介质共同决定。另外，当第一天线工作时，第一馈源产生的激励信号可经由第一天线辐射体耦合到第二天线辐射体。因此，第二天线辐射体可以通过第一缝隙的耦合产生第一天线的多个谐振模态。可见，在第一天线收发电磁波信号时，不仅可以利用第一天线辐射体，还可以利用第二天线辐射体，从而实现天线组件的天线通信性能。同时，通过一个缝隙(第一缝隙)增加天线组件的谐振模态，从而实现天线组件覆盖多个频段，保证天线组件支持多载波聚合的传输需求，以及提升空间复用能力。
再次，该电子设备具有第一边、第二边和第三边。其中，第二边与第一边的一侧相邻设置，第三边与第一边的另一侧相邻设置。

最后，本申请实施例通过将第一缝隙限定在该电子设备的第一边上，且第一缝隙到该电子设备的第二边的距离大于30mm，以及第一缝隙到该电子设备的第三边的距离大于30mm，从而在用户持握该电子设备的第二边和第三边时，用户的手部将不易触碰或遮挡位于第一边上的第一缝隙，有效避免用户的手部遮挡第一缝隙，保证第一天线的正常工作，进而可使得上述天线组件400所应用的电子设备具有更好的通信效果。
另外，由于本申请实施例的天线组件的尺寸较小且缝隙较少，从而在该天线组件应用于电子设备的情况下，有利于减小该天线组件在电子设备中所占用的结构空间，降低该天线组件在电子设备中的布局难度，提高电子设备的整机堆叠，减少因布局该天线组件在电子设备上所开设的缝隙数，以及保证电子设备的整体外观结构的完整度。
例如，当用户将图1所示的电子设备以横屏方式玩游戏、看视频等时，即用户持握该电子设备的两条短边，为了使该电子设备的天线组件中的第一天线仍然正常工作，第一缝隙的位置应该避开用户的手部，使其不被堵缝或遮挡。因此，位于该电子设备的长边上的第一缝隙到该电子设备的顶部(该电子设备的上短边)的距离大于30mm，以及第一缝隙到该电子设备的低部(该电子设备的下短边)的距离大于30mm，从而保证第一天线能更好的工作。

可见，本申请实施例的第一天线可以覆盖LTE MHB频段、LTE UHB频段、NR MHB频段、NR UHB频段、WIFI 2.4GHz频段等，从而在满足天线通信性能的同时，实现由天线组件的第一天线覆盖多个频段，以及支持多载波聚合的传输需求。
具体的，第一天线辐射体的长度可以大于第二天线辐射体的长度。
具体的，第一馈电点到第一耦合端的长度可以大于第一馈电点到第一接地端的长度。
需要说明的是，本申请实施例可以通过设置第一馈电点在第一天线辐射体上的不同位置，实现第一天线支持不同的频段。其中，第一馈电点在第一天线辐射体上的位置越靠近第一接地端，从而可以提高第一天线辐射体的辐射效率。
具体的，第一天线可以用于支持第一谐振模态、第二谐振模态、第三谐振模态、第四谐振模态；其中，第一接地端到第一耦合端的长度为第一谐振模态中心频率对应波长的1/8至1/4倍；第二接地端到第二耦合端的长度为第二谐振模态中心频率对应波长的1/4倍；第一馈电点到第一耦合端的长度为第三谐振模态中心频率对应波长的1/4倍；第一接地端到第一耦合端的长度为第四谐振模态中心频率对应波长的3/4倍。
进一步的，第一谐振模态中心频率可以为1.5GHz至2.0GHz中的一个频率；第二谐振模态中心频率可以为2.5GHz至3.0GHz中的一个频率；第三谐振模态中心频率可以为3.0GHz至4.0GHz中的一个频率；第四谐振模态中心频率可以为4.5GHz至5.0GHz中的一个频率。
在上述天线组件400应用于本申请的电子设备的情况下，下面本申请实施例将对第一天线在电子设备中的结构布局进行具体说明。
请参阅图28，框体2800可以表示该电子设备的部分外轮廓。其中，框体2800所在竖向的一个侧边(如左侧边)表示该电子设备的第一边，框体2800所在横向的顶边表示该电子设备的第二边，框体2800所在横向的底边表示该电子设备的第三边。因此，上述天线组件400的第一天线辐射体411位于该电子设备的第一边，上述天线组件400的第二天线辐射体412位于该电子设备的第一边，第一缝隙到第二边的距离大于30mm，以及第一缝隙到第三边的距离大于30mm。

另外，第一天线辐射体411和第二天线辐射体412位于电子设备100的长边的目的在于：当用户通过电子设备100的横屏(如用户持握框体2800所在横向的顶边和/或底边)玩游戏或看视频等使用时，由于第一缝隙413位于电子设备100的长边，从而能够有效避免用户的手部遮挡第一缝隙413，保证第一天线的正常工作，进而可使得上述天线组件400所应用的电子设备具有较为良好的通信效果。
结合上述描述，该天线组件还可以包括：第二天线，第二天线包括第三天线辐射体；第三天线辐射体包括第一自由端和第三接地端，第三接地端设有第三接地点，第三天线辐射体通过第三接地端接地系统；第三天线辐射体上设有第二馈电点，第二馈电点用于连接第二馈源。
需要说明的是，在天线组件的第二天线中，第二馈源可以用于产生激励信号，并由激励信号加载在第三天线辐射体，以使得第三天线辐射体辐射电磁波信号。由于第三天线辐射体上的FH段可以等效于到地小电感，因此第三天线辐射体上的FG段可以通过第二馈源的激励产生谐振模态。同理，第三天线辐射体上的GH段可以通过第二馈源的激励产生谐振模态。因此，第三天线辐射体可以通过第二馈源的激励产生第二天线的多个谐振模态。

请参阅图29，上述天线组件400的第三天线辐射体421包括第一子辐射体(HP段)和第二子辐射体(GP段)；第一子辐射体的一端与第二子辐射体的一端弯折相连，第一子辐射体的另一端为第三接地端(H)；第二子辐射体的另一端为第一自由端(G)；第一子辐射体位于该电子设备的第一边，第二子辐射体位于该电子设备的第二边；第二馈电点(F)位于第一子辐射体或者第二子辐射体上。
其中，第一子辐射体和第二子辐射体可以是边框组件120上的一段对角边框或者印刷在边框组件120内侧上的金属体等。
需要说明的是，第一子辐射体的一端与第二子辐射体的一端弯折相连，可方便第二天线对应电子设备的角设置。其中，第二天线对应电子设备的角设置的目的在于：当用户通过电子设备100的竖屏(如用户持握框体2800所在竖向的侧边或者用户持握框体2800所在横向的底边)使用时，由于用户的手部一般握持在电子设备100的长边的下半部分或者电子设备100的下短边，因此当第二天线的一部分位于电子设备100的上短边时，第二天线很难被用户握持，从而保证第二天线的正常工作，进而可使得上述天线组件400所应用的电子设备具有较为良好的通信效果。
情形二：
请参阅图30，上述天线组件400的第三天线辐射体421位于该电子设备的第一边或者第二边。
需要说明的是，第三天线辐射体421位于电子设备100的长边或者短边上。可以理解的是，第二天线位于电子设备100的长边或者短边上。其中，第三天线辐射体421可以是边框组件120上的一段边框或者印刷在边框组件120内侧上的金属体等。
另外，第三天线辐射体421位于电子设备100的长边的目的在于：当用户通过电子设备100的横屏(如用户持握框体2800所在横向的顶边和/或底边))使用时，由于用户的手部一般握持在电子设备100的短边上，因此用户很难握持位于电子设备100的长边上的第二天线，从而保证第二天线的正常工作，进而可使得上述天线组件400所应用的电子设备具有较为良好的通信效果。
第三天线辐射体421位于电子设备100的短边的目的在于：当用户通过电子设备100的竖屏(如用户持握框体2800所在竖向的侧边或者用户持握框体2800所在横向的底边)使用时，由于用户的手部一般握持在电子设备100的长边的下半部分或者电子设备100的下短边，因此当第二天线位于电子设备100的上短边时，第二天线很难被用户握持，从而保证第二天线的正常工作，进而可使得上述天线组件400所应用的电子设备具有较为良好的通信效果。
结合上述描述，该天线组件还可以包括：天线连接体、第一匹配电路和第二匹配电路；天线连接体分别连接第一接地端和第三接地端；第一天线辐射体通过第一接地点连接第一匹配电路接地；第三天线辐射体通过第三接地端连接第二匹配电路以接地系统。
具体的，天线连接体可以是电子设备100上的不同金属结构(金属体或金属臂等)。例如，边框组件120上的一段边框、印刷在后盖组件130内侧上的金属贴片、印刷在边框组件120内侧上的金属贴片、设置在主板140上的柔性电路、印刷在主板140上的金属贴片。
可见，通过天线连接体将第一天线和第二天线连接，从而实现第一天线和第二天线的共辐射体，提高天线组件400覆盖的频段，保证天线组件400支持多载波聚合的传输需求，提升空间复用能力，进而可使得上述天线组件400所应用的电子设备具有较为良好的通信效果。
下面本申请实施例将对天线连接体、第一匹配电路和第二匹配电路在该电子设备上的结构布局进行说明。
请参阅图31和图32，天线连接体431分别连接第一接地端(B)和第三接地端(H)，第一匹配电路432串联于第一天线辐射体411和第一接地点所连接的地系统之间，第二匹配电路433串联于第三天线辐射体421和第三接地点所连接的地系统之间。
结合上述描述，该天线组件还可以包括：第三匹配电路、第四匹配电路；其中，第三匹配电路串联在第一馈电点与第一馈源之间；第四匹配电路串联在第二馈电点与第二馈源之间。
下面本申请实施例将对第三匹配电路、第四匹配电路在该电子设备上的结构布局进行说明。
请参阅图33和图34，第三匹配电路441串联在第一馈电点(A)与第一馈源414之间，第四匹配电路442串联在第二馈电点(F)与第二馈源422之间。
结合上述描述，该天线组件还可以包括：第三天线，第三天线包括第四天线辐射体；第四天线辐射体与第三天线辐射体端之间存在第二缝隙；第四天线辐射体包括第二自由端和第四接地端，第一自由端和第二自由端分别位于第二缝隙两侧并通过第二缝隙耦合，第四接地端设有第四接地点；第四天线辐射体上设有第三馈电点，第三馈电点用于连接第三馈源。
其中，第四天线辐射体可以是电子设备100上的不同金属结构(金属体或金属臂等)。例如，边框组件120上的一段边框、印刷在后盖组件130内侧上的金属贴片、印刷在边框组件120内侧上的金属贴片、设置在主板140上的柔性电路、印刷在主板140上的金属贴片。
需要说明的是，在天线组件400的第三天线中，首先，第三馈源453可以用于产生激励信号，并由激励信号加载在第四天线辐射体451，以使得第四天线辐射体451辐射电磁波信号。由于第四天线辐射体451上的第三馈电点(K)到第四接地端(J)可以等效于到地小电感，因此第三馈电点(K)到第二自由端(I)可以通过第三馈源453的激励产生谐振模态。同理，第二自由端(I)到第四接地端(J)可以通过第三馈源453的激励产生谐振模态。可见，第四天线辐射体451可以用于通过第三馈源453的激励产生多个谐振模态。可见，通过在天线组件400中增加第三天线，从而增加天线组件400的谐振模态，进一步实现天线组件400覆盖多个频段，以及保证天线组件400支持多载波聚合的传输需求。
其次，由于第三天线辐射体421和第四天线辐射体451间隔设置(即二者之间存在第二缝隙445)，即第四天线辐射体451和天线单元2共口径，因此第二缝隙445存在耦合，从而使得第三天线辐射体421和第四天线辐射体451相当于通过电容连接。当第三天线工作时，不但可以利用自身的第四天线辐射体451来收发电磁波信号，还可以利用天线单元1以及天线单元2来收发电磁波信号，从而进一步提高天线组件400覆盖的频段，保证天线组件400支持多载波聚合的传输需求，以及提升空间复用能力。
最后，通过第三天线辐射体421和第四天线辐射体451间隔设置，本申请实施例可以将第四天线辐射体442看作天线单元3。因此，天线单元1和天线单元2耦合，以及天线单元2和天线单元3耦合，从而提高天线组件400覆盖的频段，保证天线组件400支持多载波聚合的传输需求，以及提升空间复用能力。
具体的，第三天线可以用于支持以下至少一种频段：N78频段、N79频段、WIFI 5GHz频段。
可见，本申请实施例的第三天线可以覆盖N78频段、N79频段、WIFI 5GHz频段等，从而在满足天线通信性能的同时，进一步实现天线组件400覆盖多个频段，以及保证天线组件400支持多载波聚合的传输需求。
具体的，第二自由端(I)到第三馈电点(K)的长度可以小于第三馈电点(K)到第四接地端(J)的长度。
需要说明的是，本申请实施例可以通过设置第三馈电点(K)在第四天线辐射体451上的不同位置，实现第三天线覆盖不同的频段。其中，第三馈电点(K)在第四天线辐射体451上的位置越远离第四接地端(J)，即第二自由端(I)到第三馈电点(K)的长度小于第三馈电点(K)到第四接地端(J)的长度，从而可以提高第四天线辐射体451的辐射效率。
具体的，第三天线用于支持第七谐振模态、第八谐振模态、第九谐振模态、第十谐振模态；其中，第七谐振模态的电流分布是从第三馈电点到第三接地端；第四接地端到第二自由端的长度为第八谐振模态中心频率对应波长的1/8至1/4倍；第三馈电点到第二自由端的长度为第九谐振模态中心频率对应波长的1/4倍；第三接地端到第一自由端的长度为第十谐振模态中心频率对应波长的3/4倍。
进一步的，第七谐振模态中心频率可以为3.0GHz至3.5GHz中的一个频率；第八谐振模态中心频率可以为3.5GHz至4.0GHz中的一个频率；第九谐振模态中心频率可以为5.0GHz至6.0GHz中的一个频率； 第十谐振模态中心频率可以为6.0GHz至7.0GHz中的一个频率。
下面本申请实施例将对第三天线在该电子设备上的结构布局分情形进行说明。

其中，第三子辐射体和第四子辐射体可以是边框组件120上的一段对角边框或者印刷在边框组件120内侧上的金属体等。
需要说明的是，第三子辐射体的一端与第四子辐射体的一端弯折相连，可方便第三天线对应电子设备的角设置。其中，第三天线对应电子设备的角设置的目的在于：当用户通过电子设备100的竖屏(如用户持握框体2800所在竖向的侧边或者用户持握框体2800所在横向的底边)使用时，由于用户的手部一般握持在电子设备100的长边的下半部分或者电子设备100的下短边上，因此当第三天线的一部分位于电子设备的上短边时，而第二缝隙452位于电子设备100的长边的上半部分，，从而能够有效避免用户的手部遮挡第二缝隙452，保证第三天线的正常工作，进而可使得上述天线组件400所应用的电子设备具有较为良好的通信效果。
情形二：
请参阅图36，第四天线辐射体451位于电子设备的第二边。
请参阅图37，第四天线辐射体451位于电子设备的第一边。
需要说明的是，第四天线辐射体451位于电子设备100的长边或者短边上。可以理解的是，第三天线位于电子设备100的长边或者短边上。其中，第四天线辐射体451可以是边框组件120上的一段边框或者印刷在边框组件120内侧上的金属体等。
另外，第四天线辐射体451位于电子设备100的长边的目的在于：当用户通过电子设备100的竖屏(如用户持握框体2800所在竖向的侧边或者用户持握框体2800所在横向的底边)使用时，由于第二缝隙452位于电子设备100的长边的上半部分，而用户的手部一般握持在电子设备100的长边的下半部分或者电子设备100的下短边，从而能够有效避免用户的手部遮挡第二缝隙452，保证第三天线的正常工作，进而可使得上述天线组件400所应用的电子设备具有较为良好的通信效果。
第三天线辐射体421位于电子设备100的短边的目的在于：当用户通过电子设备100的竖屏(如用户持握框体2800所在竖向的侧边或者用户持握框体2800所在横向的底边)使用时，由于第二缝隙452位于电子设备100的上短边，而用户的手部一般握持在电子设备100的长边的下半部分或者电子设备100的下短边，从而能够有效避免用户的手部遮挡第二缝隙452，保证第三天线的正常工作，进而可使得上述天线组件400所应用的电子设备具有较为良好的通信效果。
结合上述描述，该天线组件还可以包括：第五天线辐射体；第五天线辐射体的一端连接第一馈电点，第五天线辐射体的另一端为自由端。
其中，第五天线辐射体可以是电子设备100上的不同金属结构(金属体或金属臂等)。例如，边框组件120上的一段边框、印刷在后盖组件130内侧上的金属贴片、印刷在边框组件120内侧上的金属贴片、设置在主板140上的柔性电路、印刷在主板140上的金属贴片。
需要说明的是，本申请实施例通过在第一天线中增加第五天线辐射体471，从而增加第一天线的谐振模态，保证天线组件的调试更加灵活，提升天线组件的天线效率，进一步实现天线组件400覆盖多个频段，以及保证天线组件400支持多载波聚合的传输需求。
另外，本申请实施例可以将第五天线辐射体471看作天线单元4。
下面本申请实施例将对第五天线辐射体在该电子设备上的结构布局进行说明。
请参阅图38，第五天线辐射体471的一端连接第一馈电点(A)，第五天线辐射体的另一端为自由端。
结合上述描述，由于电子设备可以包括至少一个按键，比如电源键、音量键、静音键。例如，电子设备100的边框组件120需要开设一定空隙用于安置按键，或者不开设空隙而利用触控式在边框组件120内侧安置按键。因此，当上述天线组件400应用于电子设备时，如何实现天线组件400和按键的结构布局，以提高电子设备的整机堆叠，下面进行具体说明。
具体的，电子设备还包括至少一个按键；第一天线辐射体411环绕或围绕按键设置；或者，第二天线辐射体412环绕或围绕按键设置；或者，第三天线辐射体421环绕或围绕按键设置；或者，天线连接体431环绕或围绕按键设置；或者，第四天线辐射体451环绕或围绕按键设置。
需要说明的是，若电子设备100的边框组件120需要开设一定空隙用于安置按键，且第一天线辐射体411为边框组件120的一段边框，则第一天线辐射体411上需要开设该空隙以用于安置该按键。此时，第一天线辐射体411环绕该按键设置。或者，若电子设备100的边框组件120不需要开设一定空隙，而利用触控式在边框组件120内侧安置按键，且第一天线辐射体411为边框组件120的一段边框，则该按键可以靠近第一天线辐射体411设置，即第一天线辐射体411围绕该按键设置。其余天线辐射体与按键的结构布局同理可知，对此不再赘述。
示例性的，请参阅图39，电子设备包括按键3901和按键3902。其中，第二天线辐射体412环绕或围绕按键3901设置，天线连接体431环绕或围绕按键3902设置。可见，通过天线组件400和按键的结构布局，从而有利于提高电子设备的整机堆叠。
结合上述图14、图23和图24的描述，当天线组件400应用于电子设备时，为了实现该电子设备具备SAR检测的能力，需要通过隔直器件将上述天线组件400的天线单元1/天线单元2/天线单元3作为相对于馈源和/或地系统中的直流电路悬浮的金属体。
具体的，第一馈源和第一天线辐射体之间串联有隔直器件；第二馈源和第三天线辐射体之间串联有隔直器件；第三馈源和第四天线辐射体之间串联有隔直器件；第一天线辐射体和第一接地点所连接的地系统之间串联有隔直器件；第三天线辐射体和第三接地点所连接的地系统之间串联有隔直器件；第二天线辐射体和第二接地点所连接的地系统之间串联有隔直器件。
其中，该隔直器件可以包括隔直电容或者隔直电路。
结合描述，在通过隔直电容将上述天线组件400的天线单元1/天线单元2/天线单元3作为相对于馈源和/或地系统中的直流电路悬浮的金属体的情况下，本申请实施例的电子设备包括接近传感器，从而通过接近传感器和天线组件400实现电子设备的SAR检测能力。
具体的，电子设备还可以包括：接近传感器和至少一个检测支路；检测支路用于连接接近传感器和天线组件400；接近传感器用于通过天线组件400检测电容信号变化以判断用户是否靠近或远离该电子设备。
进一步的，该检测支路可以包括信号过滤器件。
需要说明的是，该检测支路中加入信号过滤器件可以隔离或过滤较高频率信号，从而保证天线组件400不受该检测支路的影响。
进一步的，信号过滤器件可以包括电感或者信号过滤电路。其中，该电感的电感值可以为82nH，从而对上述天线组件400的影响较小。
进一步的，该接近传感器可以设置在电子设备100内的主板140上，该检测支路可以设置在电子设备100内的主板140上。
示例性的，请参阅图40，电子设备还包括接近传感器4001、电感L3、电感L4和电感L5。其中，接近传感器4001通过电感L3连接天线单元3的线路可以看作检测支路。同理，接近传感器4001通过电感L4连接天线单元2的线路可以看作检测支路，接近传感器4001通过电感L5连接天线单元1的线路可以看作检测支路。
