参考图1，图1为本申请实施例提供的电子设备100的第一种结构示意图。
电子设备100包括显示屏11、壳体12、电路板13以及电池14。
其中，显示屏11设置在壳体12上，以形成电子设备100的显示面，用于显示图像、文本等信息。所述显示屏11可以包括液晶显示屏(Liquid Crystal Display，LCD)或有机发光二极管显示屏(Organic Light-Emitting Diode，OLED)等类型的显示屏。

该显示屏11可以包括显示区域和非显示区域。该显示区域可以用来显示电子设备100的画面或者供用户进行触摸操控等。该非显示区域的顶部区域开设供声音、及光线传导的开孔，该非显示区域底部上可以设置指纹模组、触控按键等功能组件。
需要说明的是，该显示屏11的结构并不限于此。比如，该显示屏11可以为全面屏或异形屏。还需要说明的是，在一些实施例中，显示屏11也可以不包括非显示区域，而设置成全面屏结构，可以将距离传感器、环境光传感器等功能组件设置于显示屏下方或其他位置处。其中，盖板适合显示屏的大小设置。
壳体12用于形成电子设备100的外部轮廓，以便于容纳电子设备100的电子器件、功能组件等，同时对电子设备内部的电子器件和功能组件形成密封和保 护作用。例如，电子设备100的摄像头、电路板、振动马达都功能组件都可以设置在壳体12内部。
该壳体12可以包括中框和后盖，中框和后盖相互组合形成该壳体12，该中框和后盖可以形成收纳空间，以收纳电路板13、显示屏11、电池14等器件。进一步的，盖板可以固定到壳体12上，该盖板和壳体12形成密闭空间，以容纳电路板13、显示屏11、电池14等器件。在一些实施例中，盖板盖设到中框上，后盖盖设到中框上，盖板和后盖位于中框的相对面，盖板和后盖相对设置。
在一些实施例中，壳体12可以为金属壳体，比如镁合金、不锈钢等金属。需要说明的是，本申请实施例壳体12的材料并不限于此，还可以采用其它方式，比如：壳体12可以为塑胶壳体。还比如：壳体12为陶瓷壳体。再比如：壳体12可以包括塑胶部分和金属部分，壳体12可以为金属和塑胶相互配合的壳体结构，具体的，可以先成型金属部分，比如采用注塑的方式形成镁合金基板，在镁合金基板上再注塑塑胶，形成塑胶基板，则构成完整的壳体结构。
电路板13设置在所述壳体12内部。其中，电路板13可以为电子设备100的主板。所述电路板13上还可以集成有处理器、摄像头、耳机接口、加速度传感器、陀螺仪、马达等功能组件中的一个或多个。同时，显示屏11可以电连接至电路板13，以通过电路板13上的处理器对显示屏11的显示进行控制。
在一些实施例中，该电路板13可以固定在壳体12内。具体的，该电路板13可以通过螺钉螺接到中框上，也可以采用卡扣的方式卡配到中框上。需要说明的是，本申请实施例电路板13具体固定到中框上的方式并不限于此，还可以其它方式，比如通过卡扣和螺钉共同固定的方式。
电池14设置在壳体12内部。同时，电池14电连接至所述电路板13，以实现电池14为电子设备100供电。其中，电路板13上可以设置有电源管理电路。所述电源管理电路用于将电池14提供的电压分配到电子设备100中的各个电子器件。
其中，所述电子设备100中还设置有天线组件200。所述天线组件200用于实现电子设备100的无线通信功能，例如所述天线组件200可以用于实现近场通信(Near Field Communication，NFC)功能。所述天线组件200设置在电子设备100的壳体20内部。其中，可以理解的，所述天线组件200的部分器件可以集 成在所述壳体12内部的电路板13上，例如所述天线组件200中的信号处理芯片以及信号处理电路可以集成在所述电路板13上。此外，所述天线组件200的部分器件还可以直接设置在所述壳体12内部。例如所述天线组件200的天线可以直接设置在所述壳体12内部。
在现有技术当中，随着网络设备由4G向5G的演变以及运营商准入条件的限制，5G天线设计愈加复杂。尤其是各国运营商对LB+LB随机接入(EUTRA-NR Dual Connectivity，ENDC)组合的要求，比如可以为B20+N28,B28+N5,B20+N8等。然而，以上的ENDC组合需要至少三只LB天线(一支给LTE主网，两支给NR天线)才能支持。由于LB天线需要空间巨大(开缝长度30mm以上)，在目前电子设备高屏占比的极限净空下，三支LB天线布局会导致整机天线布局更为复杂及紧凑，天线间互耦影响更大。并且目前业内各家也均没有支持LB+LB ENDC的手机方案。
请参阅图2，图2为本申请实施例提供的天线组件的第一种结构示意图。该天线组件100可以包括接地平面70、第一辐射体30以及信号源35。具体的，第一辐射体30与接地平面70之间形成第一缝隙，第一辐射体30包括相对设置的第一辐射段32和第二辐射段33，第一辐射段32与第二辐射段33之间形成第二缝隙31，第一辐射段32上设置有馈电点34，并在远离第二缝隙31的一端设置有第一接地端36，第二辐射段33远离第二缝隙31的一端设置有第二接地端37。信号源35在馈电点34处与第一辐射段32连接，信号源35用于向第一辐射体30馈入激励信号，激励信号用于激励第一辐射段32谐振于第一低频模式，并激励第二辐射段33谐和接地平面70共同谐振于第二低频模式。
进一步的，在本申请实施例中，馈电点34与第二缝隙31之间的距离大于馈电点34与第一接地端36之间的距离。也就是说，馈电点34的位置相较于第二缝隙31更加接近第一接地端36。
本实施例中，第二缝隙31位于第一辐射段32和第二辐射段33之间，第二缝隙31中可以为空气，或者也可以填充非导电材质，常见的有塑料等介质。第一辐射段32和第二辐射段33之间的缝隙等效于一个耦合电容，耦合电容的大小主要跟第一辐射段32和第二辐射段33的端面的面积、第二缝隙31的宽度以及缝隙中填充的介质相关。其中，在第二缝隙31中填充非导电材质，可 以提高天线结构的结构强度，亦可以使天线结构更加美观。优选的，上述第二缝隙31的宽度可以小于1mm。
在一实施例中，继续参阅图2，天线组件还包括：电路板13、第一连接件38和第二连接件39，其中，信号源35设置在电路板13上，第一辐射段32在第一接地端36的位置通过第一连接件38与接地平面70耦合，以实现接地，第二辐射段33在第二接地端37的位置通过第二连接件39与接地平面70耦合，以实现接地。
其中，上述第一连接件38和第二连接件39可以为薄片状金属。例如，所述第一连接件38和第二连接件39可以为镁合金薄片、铝合金薄片等。所述第一连接件38和第二连接件39分别设置在第一辐射段32和第二辐射段33的接地端并与接地平面70耦合。例如，当使用金属边框作为第一辐射体时，第一连接件38和第二连接件39可以与电子设备的金属边框贴合，从而实现第一连接件38和第二连接件39与金属边框耦合。耦合后，所述第一连接件38和第二连接件39与金属边框之间即可实现电信号的传导。
在本申请实施例中，上述天线组件用于同时在两个低频频段产生第一谐振和第二谐振。具体可以通过信号源35用于向第一辐射体30馈入激励信号，激励信号用于激励第一辐射段32谐振于第一低频模式，并激励第二辐射段33谐和接地平面70共同谐振于第二低频模式。如图3所示，图3为本申请实施例提供的天线组件所产生双谐振的仿真示意图。其中，上述第一低频模式为倒F天线谐振模式，第二低频模式为环路天线模式。
进一步的，为提升天线性能，上述第一辐射段32和第二辐射段33的长度可以设置为大于30mm。
在该实施例中，第一辐射段32和第二辐射段33均无需连接额外的接地支路，仅具有单一的接地端并通过连接件即可实现接地。上述第一辐射体30所产生的双谐振，其一谐振由第一辐射段32产生，另一谐振由第二辐射段33产生。具体的，所述第一谐振由所述信号源35经过所述第一辐射段32及第一连接件38的路径激励产生，所述第二谐振由所述信号源35经过电路板13、第二连接件39以及第二辐射段33的路径激励产生。
具体的，上述第二低频模式由第一辐射段32靠近第二缝隙31的一端的电 场激励产生。且在第二低频模式的电流路径当中，电流的方向为从第二接地端37经过第二辐射段33流向第二缝隙31。这是由于第一辐射段32的末端电流最小，而第二辐射段33的接地位置也即第二接地端37电流最大，所以会产生由第二接地端37流向第二缝隙31的电流。
需要说明的是，上述接地平面70可看作为整机参考地。第一接地端36和第二接地端37还可以采用焊接的方式固定连接到整机参考地上，第一接地端36和第二接地端37还可以采用螺钉螺接锁定的方式固定连接到整机参考地上。在其他实施例中，上述第一接地端36和第二接地端37还可以通过连接线连接到整机参考地上本申请对此不做进一步限定。
进一步的，请参阅图4，在该实施例中，上述天线组件还可以包括第二辐射体40。
其中，第二辐射体40上设置馈电点，所述馈电点用于连接信号源。第二辐射体40通过第三连接件与所述接地平面70连接。
进一步的，在该实施例中，第一辐射体30可以用于发射和接收第一低频射频信号，第二辐射体40可以用于接收第二低频射频信号。其中所述第一辐射体30的第一辐射段32可以用于发射和接收4G(the 4th generation mobile communication technology，第四代移动通信技术)射频信号，所述第一辐射体30的第二辐射段33用于发射和接收5G(5th generation mobile networks或5th generation wireless systems，第五代移动通信技术)射频信号，所述第二辐射体40可以用于接收4G射频信号和5G射频信号。其中，上述4G频段可以包括B1/B2/B3/B4/B5/B6/B7/B8/B9/B12/B17/B18/B19/B20/B26/B28等，5G频段则可以包括N1/N3/N5/N8/N28/N77/N78/N79等，在该实施例中，利用第一辐射体和第二辐射体组成双连接，从而实现LB+LB ENDC组合，比如B20+N28,B28+N5,B20+N8等。
在其他实施例中，上述第一辐射体30的第一辐射段32也可以用于发射和接收5G射频信号，第一辐射体30的第二辐射段33可以用于发射和接收4G射频信号，第二辐射体40可以用于接收4G射频信号和5G射频信号。需要说明的是上述第一辐射体30的第一辐射段32、第二辐射段33以及第二辐射体40的功能可以根据实际需求进行调整。
在一实施例中，上述天线组件还可以包括第三辐射体50。
其中，第三辐射体50上设置馈电点，馈电点用于连接信号源，第三辐射体50通过第四连接件与接地平面70连接。
进一步的，在该实施例中，第一辐射体30可以用于发射和接收第一低频射频信号，第二辐射体40可以用于发射和接收第二低频射频信号，第三辐射体50可以用于发射和接收第三低频射频信号。其中第一辐射体30的第一辐射段32用于发射和接收4G射频信号，第一辐射体30的第二辐射段33用于发射和接收5G射频信号，第三辐射体50用于接收4G射频信号和5G射频信号。在该实施例中，利用第一辐射体和第三辐射体组成双连接。
在一实施例中，还可以将上述第一辐射体30的第一辐射段32用于发射和接收4G射频信号，第一辐射体30的第二辐射段33用于发射和接收5G射频信号，第二辐射体40用于接收4G射频信号，第三辐射体50用于接收5G射频信号。当然，上述第一辐射体30的第一辐射段32、第二辐射段33、第二辐射体40以及第三辐射体50的各自功能也可以根据实际需求进行调整。
在一实施例中，上述天线组件还可以包括第四辐射体60。
第四辐射体60上设置馈电点，所述馈电点用于连接信号源，所述第四辐射体60通过第五连接件与所述接地平面70连接。
在该实施例中，第一辐射体30可以用于发射和接收第一低频射频信号，第二辐射体40可以用于发射和接收第二低频射频信号、第一中频射频信号以及第一高频射频信号，第三辐射体50可以用于发射和接收第三低频射频信号，第四辐射体60可以用于发射和接收第二中频射频信号和第二高频射频信号。
上述低、中、高频射频信号所使用的频段均不相同，举例来说，低频段比如为700-960MHz、中频段比如为1710-2170MHz、高频段比如为2300-2690MHz。需要说明的是，上述低、中、高频段并不限于此，还可以传输其他频段的信号。
在一实施例中，请参阅图5，在该实施例中，所述第四辐射体60与所述第三辐射体50之间还可以设置一个接地支路，比如在图中的接地端91位置处设置接地支路，该接地支路上还可以设置控制开关92，用来控制接地状态。
需要说明的是，上述第二辐射体40同样可以设置一个接地支路，举例来说，该第二辐射体40上设置缝隙，该缝隙将第二辐射体40分为两段辐射段， 两个辐射段均可以通过连接件或接地支路的方式来进行接地，如图5当中所示，可以在第二辐射体40的一个辐射段上通过连接件连接接地平面70进行接地，在另一个辐射段上通过接地支路进行接地。其中上述接地支路上也可以设置一个控制开关42，比如，在接地端41出设置接地支路并在接地支路上设置控制开关42。
在一实施例中，上述第一辐射体30、第二辐射体40、第三辐射体50以及第四辐射体60均可以使用电子设备的金属边框来进行辐射。比如电子设备包括矩形的金属边框，该金属边框进一步包括底边和两个侧边，分别为左侧侧边和右侧侧边，优选的，可以将第一辐射体30设置在左侧侧边，将第四辐射体60和第三辐射体50设置在底边，将第二辐射体40设置在右侧侧边。
继续参阅图6，在该实施例中，还可以在金属边框的一个侧边上设置两个天线辐射体，比如将第一辐射体30和第二辐射体40均设置在左侧侧边，将第四辐射体60和第三辐射体50设置在底边。在该实施例中，第一辐射体30和第二辐射体40均包括一个缝隙，第一辐射体30和第二辐射体40均设置一个馈电点，并在上述馈电点处设置信号源。进一步的，上述第一辐射体30的长度大于第二辐射体40。
在该实施例中，第一辐射体30和第二辐射体40可以共用一个接地端，比如第一辐射体30上设置第一接地端36、第二接地端37，第二缝隙31将第一辐射体30分为第一辐射段32和第二辐射段33。第一接地端36位于第一辐射段32上远离第二缝隙31的一端，第二接地端37位于第二辐射段33上远离第二缝隙31的一端。第一辐射段32在第一接地端36的位置通过第一连接件38与接地平面70耦合以实现接地，第二辐射段33在第二接地端37的位置通过第二连接件39与接地平面70耦合以实现接地。
在第二辐射体40当中，同样通过设置缝隙将第二辐射体40分为两个辐射段，分别为上辐射段和下辐射段，在上辐射段可以通过设置接地支路来实现接地，而在下辐射段上则可以使用上述第一连接件38与接地平面70耦合来实现接地。因此在该实施例中，第一辐射体30和第二辐射体40均设置在金属中框的同一侧，并且使用同一个接地端以及连接件来实现接地，为整机的设计节省了设备的空间，提升复用率。

接地平面；
第一辐射体，所述第一辐射体与所述接地平面之间形成第一缝隙，所述第一辐射体包括相对设置的第一辐射段和第二辐射段，所述第一辐射段与所述第二辐射段之间形成第二缝隙，所述第一辐射段上设置有馈电点，并在远离所述第二缝隙的一端设置有第一接地端，所述第二辐射段远离所述第二缝隙的一端设置有第二接地端；
信号源，所述信号源在所述馈电点处与所述第一辐射段连接，所述信号源用于向所述第一辐射体馈入激励信号，所述激励信号用于激励所述第一辐射段谐振于第一低频模式，并激励所述第二辐射段谐和所述接地平面共同谐振于第二低频模式。
在一实施例中，所述壳体包括金属边框和底壳，所述金属边框围绕所述底壳形成一收容空间，所述天线组件设置于所述收容空间内，所述第一辐射体为所述金属边框的一部分，且所述第一辐射体位于所述金属边框的侧边上。
在一实施例中，所述电子设备还包括承载板，所述承载板与所述金属边框连接并作为接地平面，所述金属边框与所述承载板之间的缝隙作为第一缝隙。
在一实施例中，所述电子设备还包括电池和电路板，所述电池和所述电路板均设置在所述承载板上，且所述金属边框上的第二缝隙的位置与所述电池对应，所述信号源设置在所述电路板上。在该实施例中，如图2所示，承载板70座位接地平面，由于承载板70的面积有限，在承载板70上设置了电池14后，信号源只能设计在电池14上方的电路板13上，且第一缝隙只有少部分分对应电路板13的位置，大部分对应电池14位置。因此馈电点必须接近第一接地端附近而无法靠近第二缝隙。也即馈电点与第二缝隙之间的距离大于馈电点与第一接地端之间的距离。
此外，可以理解的，上述边框的材质包括金属，例如包括镁合金、铝合金等金属时，所述金属边框可以用于形成系统地，所述系统地即为所述电子设备100的整机地。
本实施例中，上述电子设备可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，简称PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等等。
以上为本申请实施例提供的天线组件及电子设备，天线组件100包括接地平面、第一辐射体和信号源，第一辐射体与接地平面之间形成第一缝隙，第一辐射体包括相对设置的第一辐射段和第二辐射段，第一辐射段与第二辐射段之间形成第二缝隙，第一辐射段上设置有馈电点，并在远离第二缝隙的一端设置有第一接地端，第二辐射段远离第二缝隙的一端设置有第二接地端，信号源在馈电点处与第一辐射段连接，信号源用于向第一辐射体馈入激励信号，激励信号用于激励第一辐射段谐振于第一低频模式，并激励第二辐射段谐和接地平面共同谐振于第二低频模式。本申请实施例提供的天线组件可以在第一辐射段和第二辐射段上同时产生低频谐振，能够有效提升设备的天线辐射性能。
以上对本申请实施例提供的天线组件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。
