具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例的技术方案进行清楚地描述。
在本申请的描述中，除非另有说明，“/”表示“或”的意思，例如，A/B可以表示A或B。本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。此外，“至少一个”是指一个或多个，“多个”是指两个或两个以上。“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
下面首先结合附图对本申请实施例的应用场景进行说明。
图1是本申请实施例提供的可折叠的电子设备示意图。可折叠的电子设备是机身可折叠的电子设备。可折叠的电子设备通常包括：第一机身101，与第一机身101通过转轴转动连接的第二机身102，设置在第一机身101以及第二机身102一侧的显示屏103。基于上述结构，可折叠的电子设备可以设置为如图1中的A所示的内折式可折叠的电子设备、如图1中的B所示的外折式可折叠的电子设备以及如图1中的C所示的上下翻折式可折叠的电子设备。本申请实施例对可折叠的电子设备的折叠方式和折叠角度不做限定。
为了保证可折叠的电子设备的通信性能，可折叠的电子设备中通常设置有多个天线，用于进行不同频段的无线通信。
图2是本申请实施例提供的天线设置方式示意图。如图2所示，以内折式可折叠 的电子设备为例，内折式可折叠的电子设备可以在第一机身101的第一边框111上设置第一主频天线121(频率覆盖范围例如可以是：700MHz-3GHz)，并在第二机身102上的第二边框112上设置第二主频天线122(频率覆盖范围例如可以是：700MHz-3GHz)。
图3是本申请实施例提供的可折叠的电子设备折叠-展开状态示意图。可折叠的电子设备具有折叠状态和展开状态两种状态。其中，如图3中的A所示，折叠状态可以指第一机身101通过转轴转动时，设置在第一机身101一侧的部分显示屏与设置在第二机身102一侧的部分显示屏之间的夹角小于第一角度α(如15度)的状态。如图3中的B所示，展开状态可以指第一机身101通过转轴转动时，设置在第一机身101一侧的部分显示屏与设置在第二机身102一侧的部分显示屏之间的夹角大于第二角度β(如120度)的状态。当可折叠的电子设备由展开-折叠状态时，第一主频天线121以及第二主频天线122的相对位置关系发生变化。
由于可折叠的电子设备处于展开状态时，第一主频天线121与第二主频天线122的距离较远，第一主频天线121与第二主频天线122均可以独立工作互不干扰，而可折叠的电子设备处于折叠状态时，第一主频天线121与第二主频天线122的距离较近，因此第一主频天线121与第二主频天线122之间可能发生信号干扰，影响可折叠的电子设备的通信性能。
图4是本申请实施例提供的天线设置方式示意图。如图4所示，为了避免第一主频天线121与第二主频天线122之间的信号干扰，可折叠的电子设备可以将第一主频天线121与第二主频天线122进行规避设计。具体实现中，当可折叠的电子设备处于折叠态时，将第一主频天线121设置于第一边框111顶边靠近转轴的一侧，第二主频天线122设置于第二边框112顶边远离转轴的一侧，且第一主频天线121的投影区域与第二主频天线122的设置位置无重叠部分，此时，第一主频天线121与第二主频天线122相互独立，第一主频天线121与第二主频天线122可以对应不同的工作频段，两者互不干扰。
上述实施例的设置方式中，尽管第一主频天线121与第二主频天线122之间互不干扰，但是相互无法起到提升信号强度的作用。为此，相关技术中还提供了其他天线设置方式，以增强信号强度。
图5是本申请实施例提供的另一种天线设置方式示意图。如图5所示，可折叠的电子设备处于折叠状态时，通过调整第二主频天线122的工作频段，使得第二主频天线122成为第一主频天线121的可调寄生枝节，既可以避免第一主频天线121与第二主频天线122之间的相互干扰，又增强了第一主频天线121的信号强度，提升了可折叠的电子设备的通信性能，然而，该实施例中基于该种天线组件的结构，第一主频天线121仅发生单谐振，第二主频天线122作为可调寄生枝节同样仅发生单谐振，本申请实施例示出的天线设置方式不适用于多谐振场景。
由此可见，为了使可折叠的电子设备可以适用于多谐振场景且提高可折叠的电子设备的通信性能，本申请实施例提供了一种天线组件。本申请实施例的天线组件可以应用于电子设备。电子设备包括但不限于可折叠的电子设备。该电子设备可以设置有天线，该天线可以用于支持电子设备实现无线通信功能。其中，电子设备包括但不限于手机、平板电脑、个人电脑、工作站设备、大屏设备(例如：智慧屏、智能电视等)、 可穿戴设备(例如：智能手环、智能手表)掌上游戏机、家用游戏机、虚拟现实设备、增强现实设备、混合现实设备等、车载智能终端等。

基于上述结构，第一天线71可以在多频场景下工作，第二天线72可以对应产生多寄生谐振。
在一些实施例中，第一子天线711包括第一天线辐射体和第一馈电点7111，第一天线辐射体通过第一馈电点7111接收第一馈源输入的电信号，以使第一天线辐射体发生第一谐振以及第二谐振。
其中，第一天线辐射体可以采用包括：柔性电路板天线、冲压金属天线、激光直接成型天线的一种或多种实现，第一天线辐射体还可以复用可折叠的电子设备中的金属结构件。示例性的，当第一边框111为金属边框时，第一天线辐射体所在的对应位置可以使用金属边框实现第一天线辐射体的辐射功能。
第一馈电点7111可以是可折叠的电子设备中射频模块与天线连接的位置。为了实现天线组件中馈电的功能，第一馈电点7111处可以使用金属弹片、顶针等部件，实现第一馈源与第一天线辐射体之间的连接。以第一馈源为设置在印制电路板上的射频模块为例，在发射场景下，射频信号可以通过印制电路板上的射频电路，传输给第一馈电点7111位置的电连接部件(如上述金属弹片，顶针等)，通过电连接部件的刚性连接或者通过如印制电路板上的电子线路等带点材质的焊接，使得射频信号可以被传输到第一天线辐射体上。由此，第一天线辐射体可以以第一子天线711对应的工作频段，将射频信号以电磁波的形式传输出去。对应的，在接收场景下，以接收低频的电磁波信号为例，第一天线辐射体可以接收低频的电磁波信号，并将该低频的电磁波信号转换成模拟信号，通过第一馈电点7111反馈给射频模块，从而实现低频的电磁波信号的接收。
这里需要说明的是，第一馈电点7111实际上并非仅设置为焊接点，具体需要设置相对应的馈电结构，馈电结构中设置有匹配电路与第一天线辐射体的馈电电连接(例如弹片、螺钉等结构)，以通过第一馈电点7111使第一天线辐射体产生两个谐振。在一些实施例中，第一子天线711可以对应于第一馈电点7111设置合适的匹配网络，以使第一子天线711实现多谐振。示例的，第一子天线711通过匹配网络匹配有工作频段为1.6GHz的谐振以及2.4GHz的谐振。即第一子天线711可同时支持GPS工作频段(中心频率1.575GHz)、Wifi 2.4GHz工作频段以及N41工作频段(2.515GHz-2.675GHz)。
这里需要说明的是，第一子天线711的多频谐振可以通过四分之一波长模式、二分之一波长模式、四分之三波长模式等至少一种波长模式产生。本申请对产生多频谐振的波长模式不做限制。
在一些实施例中，第二子天线712包括第二天线辐射体和第二馈电点7121，第二天线辐射体通过第二馈电点7121接收第二馈源输入的电信号，以使第二天线辐射体发生第三谐振。
具体实现中，第二子天线712可以对应于第二馈电点7121设置合适的匹配网络， 以使第二子天线712产生至少一个频段的谐振。示例的，第二子天线712通过匹配网络匹配有工作频段为3.5GHz的谐振。
这里需要说明的是，第二子天线712对应于第二馈电点7121设置的匹配网络为第二天线辐射体上设置的匹配网络，而第二馈电点7121实际上也并非仅设置为焊接点，具体也设置有相对应的馈电结构，馈电结构中设置有匹配电路与第二天线辐射体的馈电电连接(例如弹片、螺钉等结构)，以通过第二馈电点7121与第二天线辐射体产生一个谐振。
需要注意的是，下述实施例中第一馈电点7111以及第二馈电点7121均设置有匹配网络，本申请对此不再赘述。
其中，第二馈源的馈电方式与第一馈源的馈电方式相似，本申请实施例在此不予赘述。
第一子天线711以及第二子天线712可以通过双馈设计以覆盖更多的工作频段，示例性的，当第一子天线711可以同时支持GPS工作频段以及N41工作频段时，第二子天线712可以从第二馈电点7121接收到射频信号，发生3.5GHz的第三谐振，即第二子天线712可以支持N78工作频段(3.5GHz-3.6GHz)。
需要说明的是，第一子天线711以及第二子天线712的工作频段不限于上述实施例中示出的工作频段，示例的，第二子天线712在实际工作中能够产生N78频段的谐振以及5G频段的谐振。
本申请实施例中，第三子天线713以及第四子天线714作为第一子天线711和第二子天线712的寄生枝节，接收第一子天线711和第二子天线712通过第一缝隙703以及第二缝隙706能量耦合的方式产生的馈电。

示例的，第一谐振模式可以为天线组件在GPS工作频段工作的模式，第二谐振模式可以为天线组件在N41工作频段工作的模式以及Wifi 2.4GHz工作频段工作的模式，第三谐振模式可以为天线组件在N78工作频段工作的模式。
在寄生枝节的合适位置加载电容和电感可以使第三子天线713和第四子天线714产生合适的寄生谐振。
在一些实施例中，第三子天线713包括第三辐射体、第一调谐电路7131以及第二调谐电路7132，第四子天线714包括第四天线辐射体；第一调谐电路7131以及第二调谐电路7132用于调节第三天线辐射体、以及第四天线辐射体的工作频段，以使第三天线辐射体以及第四天线辐射体发生第一寄生谐振、第二寄生谐振以及第三寄生谐振；其中，第一寄生谐振的工作频段高于第一谐振，第二寄生谐振的工作频段高于第二谐振。第三寄生谐振的工作频段高于第三谐振。
这里需要说明的是，第三天线辐射体以及第四天线辐射体接收到能量耦合后共同 作用产生多个寄生谐振，
其中，第一调谐电路7131包括第一电容和第一电感，位于靠近第三端704的一侧，第二调谐电路7132包括第二电容和第二电感，位于靠近第二缝隙706的一侧，第一调谐电路7131以及第二调谐电路7132可以通过调节电容电感的大小、接地位置等调节匹配网络进而调节第一寄生谐振、第二寄生谐振以及第三寄生谐振的工作频段，以产生多个不同频段的寄生谐振增大天线组件的带宽。
示例的，当第一谐振F1为1.6GHz，第二谐振F2为2.4GHz，第三谐振F3为3.5GHz时，第三子天线713通过加载第一电容和第一电感，以使第三天线辐射体和第四天线辐射体发生2.6GHz的第二寄生谐振Q2，第三子天线713通过加载第二电容以及第二电感，以使第三天线辐射体和第四天线辐射体发生3.8GHz的第三寄生谐振Q3，同时，由于第一电容、第一电感、第二电容、第二电感在第一谐振附近可以等效为电容，使第三子天线713以及第四子天线714被容性加载，发生1.8GHz的第一寄生谐振Q1。
图9是本申请实施例示出的回波损耗示意图。如图9所示，天线组件可以通过1.8GHz的第一寄生谐振Q1、2.6GHz的第二寄生谐振Q2、3.8GHz的第三寄生谐振Q3，使天线组件可以同时覆盖GPS工作频段、N41工作频段、Wifi 2.4GHz工作频段以及N78工作频段，提升天线组件的带宽。
这里需要说明的是，本申请实施例提供的天线组件的回波损耗图中，示出了天线组件的工作频率与反射系数S11的关系，其中，回波损耗图的横坐标为频率，单位为GHz,纵坐标为反射系数S11，单位为dB。反射系数S11是散射参数中的一个，表示回波损耗特性，一般通过网络分析仪在看其损耗的dB值和阻抗特性。反射系数S11表示天线组件与前端电路的匹配程度适配性，反射系数S11的值越大，表示天线组件本身反射回来的能量越大，天线组件的匹配就越差。例如，天线A在某一频点的S11值为-1，天线B在相同频点的S11值为-3，天线B比天线A的匹配程度好。
基于上述结构，第二天线72产生的寄生谐振不仅可以增加第一天线71的工作带宽，还可以增加第一天线71的辐射效率。具体实现中，第二天线72可以激励第一天线71以使第一天线71获取槽天线共模(Slot CM)模式或者槽天线差模(Slot DM)模式，第一天线71通过第二天线72激励的槽天线共模模式或者槽天线差模模式，形成同向的激励电流，以提升天线组件的辐射效率。
图10是本申请实施例示出的第一谐振模式的电流分布示意图。如图10所示，当天线组件在第一谐振模式工作时，第一子天线711以及第二子天线712为强电流分布的槽天线共模模式，第三子天线713以及第四子天线714的电流分布与第一子天线711同向。
图11是本申请实施例示出的第二谐振模式的电流分布示意图。如图11所示，当天线组件在第二谐振模式工作时，第一子天线711以及第二子天线712为强电流分布的槽天线共模模式，第三子天线713以及第四子天线714的电流分布与第二子天线712同向。
图12是本申请实施例示出的第三谐振模式的电流分布示意图。如图12所示，当天线组件在第三谐振模式工作时，第一子天线711以及第二子天线712为强电流分布的槽天线差模模式，第三子天线713以及第四子天线714的电流分布为自第二调谐电 路7132至第四子天线714的槽天线共模模式，与第二子天线712的电流分布同向，其中，第二调谐电路7132为靠近第二缝隙706一端的调谐电路。具体实现中，第二调谐电路7132接地，以使第二天线72中第二调谐电路7132至第四子天线714对应的电流分布模式为槽天线共模模式。
这里需要说明的是，天线组件的工作频率与交变电流的分布有关，天线组件在第一谐振模式工作时，第一天线71对应如图10所示的电流分布，此时，第二天线72产生同向的电流分布，同向的电流分布形成同向激励电流，以使第二天线72能够提升第一天线71的辐射效率，其他谐振模式同理，本申请实施例在此不予赘述。
图13和图14是本申请实施例示出的辐射效率效果对比示意图。将如图13中的A所示的本申请实施例的天线组件与如图13中的B所示的第二天线72不设置第二缝隙706的天线组件的辐射效率进行对比，可以发现，本申请实施例示出的天线组件在可折叠的电子设备处于折叠状态下，相较于第二天线72不设置第二缝隙706的天线组件，第一谐振的辐射效率提升1dB，第二谐振的辐射效率提升0.9dB，如图14所示，第三谐振的辐射效率提升0.5dB。
其中，辐射效率可以用于表示当前天线组件在多端口激励情况下，从端口输入能量与经过辐射和损耗反馈到端口的能量的差异。辐射效率越高，表明反馈到端口的能量越小，那么则能够表明当前天线组件能够达到的辐射效率的水平，而辐射效率就可以是当前天线组件能够提供的最大的辐射能力。
本申请实施例示出的第一个天线组件，是最优选的设置方式，通过设置第一调谐电路以及第二调谐电路形成最佳的匹配网络，以产生多馈多频的天线组件，能够产生多个寄生谐振，能够更好提升GPS、N41、Wifi 2.4GHz、N78工作频段的带宽，以及更好提升GPS频段、N41、Wifi 2.4GHz、N78工作频段的辐射效率。
图15是本申请实施例提供的天线组件的第二个示意图。如图15所示，本申请实施例提供的天线组件中，第一子天线711包括第一天线辐射体和第一馈电点7111，第一天线辐射体通过第一馈电点7111接收第一馈源输入的电信号，以使第一天线辐射体发生第一谐振以及第二谐振；第二子天线712包括第二天线辐射体和第二馈电点7121，第二天线辐射体通过第二馈电点7121接收第二馈源输入的电信号，以使第二天线辐射体发生第三谐振。
第三子天线713以及第四子天线714在接收到馈电后，能够产生与自身结构尺寸相对应的谐振频点，以用于提升天线组件的辐射效率，并增加天线组件的工作带宽。
具体实现中，第三子天线713和第四子天线714设计成合适的长度可以使第三子天线713和第四子天线714在对应于第一天线71的位置产生合适的寄生谐振。
在一些实施例中，第三子天线713包括第三辐射体，第四子天线714包括第四辐射体，当第三子天线713设置为第一长度且第四子天线714设置为第二长度时，第三天线辐射体以及第四天线辐射体发生第四寄生谐振，以及第五寄生谐振其中，第四寄生谐振的工作频段高于第二谐振，第五寄生谐振的工作频段高于第三谐振。第一长度需要对应于第一子天线711的长度进行设置，以及第二长度需要对应于第二子天线712的长度进行设置。这样，天线组件仅通过调节第一长度以及第二长度即可提升天线组件的辐射效率，并增加天线组件的工作带宽。
这里需要说明的是，在无法设置合适的匹配网络(例如第一个天线组件的第一调谐电路以及第二调谐电路)时，才选择通过调节长度以调节寄生谐振的位置，第二个天线组件的设置方式与第一个天线组件的设置方式相比较，尽管都可以提升天线组件的辐射效率以及天线组件的带宽，但是第一个天线组件的实际提升效果较好。示例的，当第一子天线711的长度设置为15毫米，第二子天线712的长度设置为8毫米，且第一缝隙703的长度设置为1毫米时，第三子天线713的第一长度可以设置为10毫米，第四子天线714的第二长度可以设置为7毫米，第二缝隙706的长度设置为1毫米。其中，第一长度对应于第一子天线711的长度设置，以使第三子天线713以及第四子天线714可以产生工作频率高于第二谐振的第四寄生谐振，进而增加第一子天线711的工作带宽，第二长度对应于第四子天线714的长度进行设置，以使第三子天线713以及第四子天线714可以产生工作频率高于第三谐振的第二寄生谐振，进而增加第二子天线712的工作带宽。
需要说明的是，本申请示出的第一长度以及第二长度包括但不限于上述实施例中所述的长度，第一长度以及第二长度需要根据实际情况设置，以使不同频段产生对应的寄生谐振。

示例的，当第一子天线711的长度设置为15毫米，第二子天线712的长度设置为8毫米，且第一缝隙703的长度设置为1毫米时，第三子天线713的第一长度可以设置为4毫米，第四子天线714的第二长度可以设置为3毫米，第二缝隙706的长度设置为1毫米。其中，第三长度和第四长度对应于第一天线71的长度进行设置，以使第四子天线714可以产生工作频率高于第三谐振的第三寄生谐振，进而增加第二子天线712的工作带宽。
需要说明的是，本申请示出的第三长度以及第四长度包括但不限于上述实施例中所述的长度，第三天线以及第四天线的长度需要根据实际情况设置，以使不同频段产生对应的寄生谐振。图22是本申请实施例提供的天线组件的回波损耗示意图。如图22所示，当第一谐振F1为1.6GHz，第二谐振F2为2.4GHz，第三谐振F3为3.5GHz时，第三子天线713以及第四子天线714接收到馈电，发生3.8GHz的第六寄生谐振Q6，第二子天线712的工作带宽由3.5GHz增加到3.8GHz，以使该天线组件可以覆盖N78工作频段的带宽。本申请实施例示出的天线组件的结构可以通过第六寄生谐振提高第三谐振的带宽，同时对第一谐振以及第二谐振也具有提升作用。
