详述
为使本申请实施例的目的、技术方案和优点更加清楚明白，下文中将结合附图对本申请实施例的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请实施例中的实施例及实施例中的特征可以相互任意组合。
请参照图1，图1为本申请实施例提供的一种电子设备的结构示意图。电子设备1000包括天线组件100。天线组件100用于收发电磁波信号，以实现电子设备1000的通信功能。本申请对于天线组件100在电子设备1000内的位置不做限定。电子设备1000还包括相互盖合连接的显示屏300及壳体200。
天线组件100可设于电子设备1000的壳体200内部、或部分与壳体200集成为一体、或部分设于壳体200外。图1中天线组件100的辐射体与壳体200集成为一体。当然，天线组件100可以设于电子设备1000的可伸缩组件上，换言之，天线组件100的至少部分还能够随着电子设备1000的可伸缩组件伸出电子设备1000之外，及随着可伸缩组件缩回至电子设备1000内；或者，天线组件100的整体长度随着电子设备1000的可伸缩组件的伸长而伸长。
电子设备1000包括不限于为电话、电视、平板电脑、手机、照相机、个人计算机、笔记本电脑、车载设备、耳机、手表、可穿戴设备、基站、车载雷达、客户前置设备(Customer Premise Equipment，CPE)等能够收发电磁波信号的设备。本申请中以电子设备1000为手机为例，其他的设备可参考本申请中的具体描述。
为了便于描述，以电子设备1000处于图1中的视角为参照，电子设备1000的宽度方向定义为X轴方向，电子设备1000的长度方向定义为Y轴方向，电子设备1000的厚度方向定义为Z轴方向。X轴方向、Y轴方向及Z轴方向两两垂直。其中，箭头所指示的方向为正向。
请参阅图2，壳体200包括边框210及后盖220。边框210内通过注塑形成中板410，中板410上形成多个用于安装各种电子器件的安装槽。中板410与边框210一起成为电子设备1000的中框420。显示屏300、中框420及后盖220盖合后在中框420的两侧皆形成收容空间。边框210的一侧(例如后侧)围接于后盖220的周沿，边框210的另一侧(例如前侧)围接于显示屏300的周沿。
电子设备1000还包括设于收容空间内的电池、摄像头、麦克风、受话器、扬声器、人脸识别模组、指纹识别模组等等能够实现手机的基本功能的器件，在本实施例中不再赘述。
以下结合附图对于本申请提供的天线组件100进行说明，当然，本申请提供的天线组件100包括但不限于以下的实施方式。
请参阅图3，天线组件100至少包括第一辐射体11、第二辐射体21、第一匹配模块M1、第一馈电模块13、第二匹配模块M2及第二馈电模块23。其中，为了便于从功能上划分天线组件100的不同部分以便于后续的描述，定义第一辐射体11、第二辐射体21、第一匹配模块M1及第一馈电模块13为第一天线单元10，定义第一辐射体11、第二辐射体21、第二匹配模块M2及第二馈电模块23为第二天线单元20。
请参阅图3，第一辐射体11具有第一接地端111和第一耦合端112，以及位于第一接地端111和第一耦合端112之间的第一馈电点A。本实施例中，第一接地端111与第一耦合端112为呈直线条形的第一辐射体11的相对两端。在其他实施方式中，第一辐射体11呈弯折状，第一接地端111和第一耦合端112可不沿直线方向相对，但第一接地端111和第一耦合端112为第一辐射体11的两个末端。
请参阅图3，第二辐射体21具有第二耦合端212和第二接地端211，以及位于第二耦合端212和第二接地端211之间的第二馈电点B。第二耦合端212与第一耦合端112之间存在第一耦合缝隙140。第一辐射体11与第二辐射体21能够通过第一耦合缝隙140产生容性耦合。本实施例中，第二耦合端212及第二接地端211为第二辐射体21的两个末端。可选的，第一辐射体11与第二辐射体21可沿直线排列或大致沿直线排列(即在设计过程中具有较小的公差)。
当然，在其他实施方式中，第一辐射体11与第二辐射体21还可在延伸方向上错开设置，以形成避让空间等。
请参阅图3，第一耦合端112与第二耦合端212相对且间隔设置。第一耦合缝隙140为第一辐射体11与第二辐射体21之间的断缝，例如，第一耦合缝隙140的宽度可以为0.5至2mm，但不限于此尺寸。第一辐射体11和第二辐射体21可看作为辐射体被第一耦合缝隙140隔断而形成的两个 部分。
第一辐射体11与第二辐射体21通过第一耦合缝隙140进行容性耦合。其中，“容性耦合”是指，第一辐射体11与第二辐射体21之间产生电场，第一辐射体11的信号能够通过电场传递至第二辐射体21，第二辐射体21的信号能够通过电场传递至第一辐射体11，以使第一辐射体11与第二辐射体21即使在不直接接触或不直接连接的状态下也能够实现电信号导通。
可以理解的，本申请对于第一辐射体11、第二辐射体21的形状、构造不做限定，第一辐射体11、第二辐射体21的形状皆包括但不限于条状、片状、杆状、涂层、薄膜等。当第一辐射体11、第二辐射体21呈条状时，本申请对于第一辐射体11、第二辐射体21的延伸轨迹不做限定，故第一辐射体11、第二辐射体21皆可呈直线、曲线、多段弯折等轨迹延伸。上述的辐射体在延伸轨迹上可为宽度均匀的线条，可以为宽度渐变、设有加宽区域等宽度不等的条形。
请参阅图3，第一匹配模块M1电连接于第一馈电点A与第一馈电模块13之间。第一馈电模块13为用于发送射频信号的射频收发芯片或电连接用于发送射频信号的射频收发芯片的馈电部。第一匹配模块M1可包含开关器件、电容器件、电感器件、电阻器件等中的至少一者。
请参阅图3，第一接地端111电连接至第一参考地GND1，其电连接方式包括但不限于直接焊接、或通过同轴线、微带线、导电弹片、导电胶等方式间接电连接。本申请对于第一馈电点A在第一辐射体11上的位置不做限定。
请参阅图3，第二天线单元20包括第一辐射体11、第二辐射体21、第二匹配模块M2及第二馈电模块23。
请参阅图3，第二匹配模块M2电连接于第二馈电点B与第二馈电模块23之间。第二馈电模块23为用于发送射频信号的射频收发芯片或电连接用于发送射频信号的射频收发芯片的馈电部。第二匹配模块M2包含开关器件、电容器件、电感器件、电阻器件等中的至少一者。
请参阅图3，第二接地端211电连接至第二参考地GND2，其电连接方式包括但不限于直接焊接、或通过同轴线、微带线、导电弹片、导电胶等方式间接电连接。本申请对于第二馈电点A在第二辐射体21上的具体位置不做限定。
第一参考地GND1和第二参考地GND2包括但不限于以下几种实施方式。可选的，天线组件100自身具有参考地。该参考地的具体形式包括但不限于金属导电板件、成型于柔性电路板内部、硬质电路板中的金属导电层等。其中，第一参考地GND1和第二参考地GND2可为天线组件100中的一体成型的一个参考地，可以为天线组件100中的两个相互独立但相互连接的参考地。当天线组件100设于电子设备1000内时，天线组件100的参考地电连接至电子设备1000的参考地。再可选的，天线组件100本身不具有参考地，天线组件100的第一接地端111和第二接地端211通过直接电连接或通过导电件间接电连接至电子设备1000的参考地或电子设备1000内的电子器件的参考地。本申请中，天线组件100设于电子设备1000，以中板410上的金属合金作为参考地GND。即第一参考地GND1和第二参考地GND2为中板410的一部分或电连接至中板410，后续的第三参考地GND3至第七参考地GND7皆为参考地GND的一部分。
所述第一辐射体11在第一馈电模块13激励下支持第一谐振模式，其中所述第一谐振模式支持低频频段。
其中，低频频段为小于1Ghz的频段，其中该第一谐振模式所支持的频段可以为低频的全频段，或者，低频频段中的一个或多个的子频段。
一些示例性实施例中，增加第一辐射体11的有效电长度，以使得第一辐射体11在第一馈电模块13激励下支持低频频段。一些示例性实施例中，第一辐射体11的有效电长度为第一馈电模块13提供的电流频率在介质中的波长的1/8至1/4倍，其中，波长是指电磁波在所处环境中的介质中的波长。由于1/8至1/4波长模式为效率相对较高的谐振模式，因此，采用1/8至1/4倍波长的有效电长度，可以利于产生谐振模式，使电流谐振于第一辐射体11上的1/8至1/4波长模式。
由于第一辐射体11与第二辐射体21容性耦合，第二馈电模块23产生的电流也能够谐振于第一辐射体11和第二辐射体21中至少一个，第一辐射体11和第二辐射体21既能够作为第一天线单元10的辐射体，还能够作为第二天线单元20的辐射体，相较于第二馈电模块23单独谐振于第二辐射体21上，本申请实施例提供的天线组件100中的第一天线单元10和第二天线单元20实现了 共口径辐射，能够产生更多的谐振模式。从另一角度上说，本申请实施例提供的天线组件100，在支持到所需频段(或者在支持到所需谐振模式数量)的同时，充分复用了辐射体，减小的第一辐射体11和第二辐射体21的堆叠长度。
一些示例性实施例中，通过第二馈电模块23在第一辐射体11或第二辐射体21谐振，使得天线组件在第二馈电模块激励下支持多个谐振模式。
一些示例性实施例中，第二馈电模块23提供的电流谐振于第二辐射体21上，产生谐振模式；此外，由于第一辐射体11与第二辐射体21容性耦合，第二馈电模块23提供的电流还经第一耦合缝隙140传送至第一辐射体11上，以在第一辐射体11上产生谐振模式，增加第二天线单元10所支持的谐振模式数量。
一般地，电子设备(如，手机)所使用的馈电模块提供的电流频率均在高频频段，通过设计第一馈电模块21提供的电流频率为预设的低频频段，可以有效地与常规的电子设备中的馈电模块所产生的频率产生差别，使得天线组件100整体所覆盖的频段宽度和频段数量得到增加。
一些示例性实施例中，第一辐射体11的有效电长度约为第二馈电模块23提供的电流频率在介质中的波长的1/8至1/4倍，其中，波长是指电磁波在所处环境中的介质中的波长。可以利于产生谐振模式，使电流谐振于第二辐射体21上的1/8至1/4波长模式，其中，1/8至1/4波长模式为效率相对较高的谐振模式，故能够增加第二天线单元20所支持的谐振模式的数量及对于所支持的频段的收发效率，实现第二天线单元20在第一辐射体11和第二辐射体21上皆产生谐振模式。相较于第二天线单元20的电流仅仅谐振于第二辐射体11上，增加了第二天线单元20所支持的谐振模式的数量并产生较高的信号转换效率，进而增加天线组件100所支持的谐振模式的数量。
天线组件100所支持的谐振模式的数量增加，天线组件100所覆盖的频段宽度、频段数量增加。一些示例性实施例中，第一方面，当天线组件100的多种谐振模式所支持的频段皆连续时，此天线组件100所支持的频带宽度较宽，能够形成超宽带，该超宽带为低频、1G、1.5G或2G等等，以实现超宽带覆盖，提升下载带宽，提升吞吐量下载速度，提升用户的上网体验；第二方面，当天线组件100的多种谐振模式所支持的频段不连续时，此天线组件100所支持的频段数量增加，实现多频段的覆盖，例如天线组件100所支持的频段可同时覆盖低频、4G/5G中高频(例如1000MHz至3000MHz)和4G/5G超高频(例如3000MHz至10000MHz)、同时支持两个不同频段的中高频、同时支持4G/5G中高频和WiFi频段(例如WiFi5G、5.925GHz至7.125GHz等)等等。其中，多种谐振模式所支持的频段连续是指多种谐振模式所支持的相邻的两个频段至少部分重合。多种谐振模式所支持的频段不连续是指多种谐振模式所支持的相邻的两个频段之间无重合。
当天线组件100用于覆盖两种不同通信协议的信号(例如移动通信4G/5G信号和WiFi信号)时，第一天线单元10所能够支持的谐振模式相对较多，所覆盖的频段宽度相对较宽及所支持的频段数量相对较多，能够使第一天线单元10支持其中一种需要更多谐振模式支持的通信协议信号(例如移动通信N77频段或N78频段的信号)，而第二天线单元20既可以支持另一种通信协议信号(例如，4G/5G信号)。如此，避免一个天线单元支持两种不同的通信协议信号时需要设置合路器等器件而导致射频链路上的损耗增加。
本申请提供的天线组件100及电子设备1000，通过设计第一辐射体11与第二辐射体21容性耦合，第一辐射体11和第二辐射体21作为第一天线单元10、第二天线单元20的共口径辐射体，并设计第一辐射体11的长度与第二馈电模块23提供的激励电流的谐振频率的1/8至1/4波长相对应，使第二馈电模块23传送的电流谐振于第二辐射体21的同时，还能够通过第一耦合缝隙140谐振于第一辐射体11上的1/8至1/4波长模式，故能够增加第二天线单元20所支持的谐振模式的数量及对于所支持的频段的收发效率，进而增加第二天线单元20所支持的频段数量或带宽，提高数据传输速率和通信质量，还便于第二天线单元20支持同一协议标准的信号，避免将不同协议标准的信号通过一个辐射体收发而产生的射频链路损耗，提高天线单元100的结构简洁性及减小射频链路损耗。
请参阅图4，第一天线单元10支持第一谐振模式a，图4是第一天线单元10的S参数曲线图；其中，第一谐振模式a的谐振频率为0.7468GHz。
其中，谐振模式表征为天线组件100在谐振频率处及谐振频率附近具有较高的电磁波收发效率。该谐振频率为谐振模式的谐振频率，该谐振频率及其附近形成该谐振模式所支持或所覆盖的频段。可选的，在回波损耗曲线中，取回波损耗值的绝对值大于或等于5dB(仅仅为举例，并不能作为本申请 对于较高的效率的回波损耗值的限制)为具有较高的电磁波收发效率的参考值。取一个谐振模式中回波损耗值的绝对值大于或等于5dB的频率的集合为该谐振模式所支持的频段。
一些示例性实施例中，请结合参阅图4及图5，第一谐振模式a为第一馈电模块13提供的激励电流(即第一谐振电流)谐振于第一辐射体11上的1/8至1/4波长模式。
一些示例性实施例中，通过设计第一辐射体11的长度约为第一馈电模块13发送至第一辐射体11的激励电流在介质中的波长的1/8至1/4倍，以在第一辐射体11上激励起第一谐振模式a，在第一谐振模式a所支持的频段具有较高的辐射效率。
一般地，通过设计第一辐射体11的长度约为第一馈电模块13发送至第一辐射体11的激励电流在介质中的波长的1/4倍，在第一谐振频点f1(第一谐振模式a的谐振频率)易激励起较高的辐射效率。通过在第一谐振电流的路径上设置接地的容性的匹配电路，以实现容性耦合馈入第一辐射体11上，容性加载皆可使得第一谐振模式a的谐振频率朝向低频偏移，不再遵循原本的需要在第一辐射体11的长度约为1/4波长处产生较高效率的谐振，而是可以在第一辐射体11的长度对应1/8至1/4波长的范围内，能够产生较高效率的谐振，故在原来的第一谐振频点f1形成谐振的同时还能够使所对应的第一辐射体11的长度缩短，例如，减小至第一谐振频点f1对应的波长的1/8倍等，减小第一辐射体11的尺寸，减小天线组件100的堆叠长度。
请参阅图6，所述第二天线单元20支持第二谐振模式b、第三谐振模式c、第四谐振模式d和第五谐振模式e。其中，第二谐振模式b的谐振频率为1.88GHz，第三谐振模式c的谐振频率为2.6323GHz，第四谐振模式d的谐振频率为3.5707GHz，第五谐振模式e的谐振频率为3.822GHz。
可选的，第二辐射体11在第二馈电模块13的激励下至少支持第二谐振模式b、第三谐振模式c、第四谐振模式d和第五谐振模式e。
请参阅图7A，第二谐振模式b的第二谐振电流密度主要分布于第二接地端211与第二耦合端212之间，从第二接地端211流向第二耦合端212，或者从第二耦合端212流向第二接地端211。可以理解的，上述为第二谐振模式b的主要的电流密度分布，在第一辐射体11上也具有少量的电流密度分布。
一些示例性实施例中，请结合参阅图6及图7A，第二谐振模式b为第二馈电模块23提供的激励电流(即第二谐振电流)谐振于第二辐射体11上的1/8至1/4波长模式。
一些示例性实施例中，通过设计第二辐射体21的长度约为第二馈电模块23发送至第二辐射体21的激励电流在介质中的波长的1/8至1/4倍，以在第二辐射体21上激励起第二谐振模式b，在第二谐振模式b所支持的频段具有较高的辐射效率。
一般地，通过设计第二辐射体21的长度约为第二馈电模块23发送至第二辐射体21的激励电流在介质中的波长的1/4倍，在第二谐振频点f2(第二谐振模式b的谐振频率)易激励起较高的辐射效率。通过在第二谐振电流的路径上设置接地的容性的匹配电路，以实现容性耦合馈入第二辐射体21上，容性加载皆可使得第二谐振模式b的谐振频率朝向低频偏移，不再遵循原本的需要在第二辐射体21的长度约为1/4波长处产生较高效率的谐振，而是可以在第二辐射体21的长度对应1/8至1/4波长的范围内，能够产生较高效率的谐振，故在原来的第二谐振频点f2形成谐振的同时还能够使所对应的第二辐射体21的长度缩短，例如，减小至第二谐振频点f2对应的波长的1/8倍等，减小第二辐射体21的尺寸，减小天线组件100的堆叠长度。
可选的，请参阅图7B，第三谐振模式c的第三谐振电流密度主要分布于第一馈电点A与第一耦合端112之间。从第二馈电点B流向第二耦合端212，经第一耦合缝隙140后再从第一耦合端112流向第一馈电点A。可以理解的，上述为第三谐振模式c的主要的电流密度分布，在第一接地端111与第一馈电点A之间也具有少量的电流密度分布。
请结合参阅图6及图7B，第三谐振模式c为第二馈电模块13提供的激励电流(第三谐振电流)谐振于第一辐射体21上的1/4波长模式。一些示例性实施例中，由于第一馈电模块13所提供的电流频率小于第二馈电模块23所提供的电流频率，且所述第一辐射体11的长度为第一馈电模块13的激励电流在介质中的波长的1/8至1/4倍，因此，第一辐射体11的长度大于第二馈电模块23的激励电流在介质中的波长的1/8至1/4倍，因此，第一辐射体11能够支持第二馈电模块23在第一辐射体11上激励起第三谐振模式c。
其中，第一匹配模块M1还包括至少一个电连接至第三参考地的支路R，其中所述控制支路R在天线组件100工作于第三谐振模式时选通。其中，该支路在下文中关于第一匹配模块M1的部分再进行详细说明。
一般地，通过设计第一辐射体11的长度约为第二馈电模块23发送的激励电流在介质中的波长的1/8至1/4倍，此时，在第三谐振频点f3(第三谐振模式c的谐振频率处)易激励起较高的辐射效率。通过在第三谐振电流的路径上设置接地的容性的匹配电路，以实现容性耦合馈入第一辐射体11上，容性加载皆可使得第三谐振模式c的谐振频率朝向低频偏移，不再遵循原本的需要在第一辐射体11的长度约为1/4波长处产生较高效率的谐振，而是可以在第一辐射体11的长度对应1/8至1/4波长的范围内，能够产生较高效率的谐振，故在原来的第三谐振频点f3形成谐振的同时还能够使所对应的第一辐射体11的长度缩短，例如，减小至第三谐振频点f3对应的波长的1/8倍等，减小第一辐射体11的尺寸，减小天线组件100的堆叠长度。
请一并参阅图6及图7C，第四谐振模式d为第二馈电模块13提供的激励电流(第四谐振电流)谐振于第二馈电点B至第二耦合端212的1/4波长模式。一些示例性实施例中，通过设计第二馈电点B至第二耦合端212的长度约为第二馈电模块23发送至第二辐射体21的激励电流在介质中的波长的1/8至1/4倍，以在第二馈电点B至第二耦合端212上激励起第三谐振模式c。
请参阅图7D，所述第一辐射体11具有位于所述第一馈电点A和第一耦合端112之间的接地点；所述天线组件还包括滤波电路S，其中所述滤波电路S的一端连接至所述接地点，所述滤波电路S的另一端连接至地；
所述天线组件100用于支持第五谐振模式，其中所述第五谐振模式为所述第二馈电模块23的激励电流谐振于所述接地点至所述第一耦合端112之间的1/4波长模式；
所述滤波电路S用于导通所述第五谐振模式所支持的频段以及阻断所述第五谐振模式所支持的频段之外的其他频段。
一些示例性实施例中，所述滤波电路S包括第一滤波支路和第二滤波支路中至少一个，其中：所述第一滤波支路包括串联的第一电感与第一电容；所述第二滤波支路包括第二电容、第二电感、及第三电感，所述第二电容与所述第二电感串联，所述第三电感的一端连接至所述第二电容未连接第二电感的一端，所述第三电感的另一端连接至所述第二电感未连接所述第二电容的一端。
请一并参阅图6及图7D，第五谐振模式e为第二馈电模块23提供的激励电流(第五谐振电流)谐振于接地点至第一耦合端112之间的1/4波长模式。一些示例性实施例中，通过设计接地点至所述第一耦合端112的长度约为第二馈电模块23发送至第一辐射体11的激励电流在介质中的波长的1/4倍，以在接地点至第一耦合端112上激励起第五谐振模式e。
一般地，通过设计第二馈电点B至第二耦合端212的长度约为第二馈电模块13发送的激励电流在介质中的波长的1/4倍，此时，在第五谐振频点f5处(第五谐振模式e的谐振频率)易激励起较高的辐射效率。通过在第五谐振电流的路径上设置接地的容性的匹配电路，以实现容性耦合馈入第一辐射体11上，容性加载皆可使得第五谐振模式e的谐振频率朝向低频偏移，不再遵循原本的需要在第二馈电点B至第二耦合端212的长度约为1/4波长处产生较高效率的谐振，而是可以在第一辐射体11的接地点至第一耦合端112的长度对应1/4波长的范围内，能够产生较高效率的谐振，故在原来的第五谐振频点f5形成谐振的同时还能够使所对应的第二馈电点B至第二耦合端212的长度缩短，例如，减小至第五谐振频点f5对应的波长的1/8倍等，减小第二馈电点B至第二耦合端212的尺寸，减小天线组件100的堆叠长度。
一些示例性实施例中，通过在第一辐射体11上设置接地点，增加了第二馈电模块23在第一辐射体11上激励产生的谐振模式的数量，有效地提高第二天线单元20所覆盖的频段数量、频段宽度等，提高天线组件100传输数据速率。
通过对于第一辐射体11的长度、第一馈电点A与第一耦合端112之间的长度以及第二辐射体21的长度进行设计，以使第二馈电模块23能在第一辐射体11及第二辐射体21上皆激励起谐振模式，提高第二天线单元20所能够支持的谐振模式的数量，有效地提高第二天线单元10所覆盖的频段数量和频段宽度等，提高天线组件100传输数据速率。
可选的，第二谐振模式b、第三谐振模式c、第四谐振模式b或第五谐振模式e所支持的频段包 括GPS频段、或LTE 4G频段、或NR 5G频段、或Wi-Fi 2.4G频段、或Wi-Fi 5G频段、或Wi-Fi 6E频段、或LTE 4G频段与NR 5G频段形成的组合频段等。一个谐振模式所支持的频段可以是单独的LTE 4G频段、或单独的NR 5G频段、或单独的Wi-Fi频段、或LTE 4G频段与NR 5G频段形成的组合频段等。
本申请中，第二谐振模式b的谐振频率的大小、第三谐振模式c的谐振频率的大小、第四谐振模式d以及第五谐振模式e的谐振频率的大小不做限定。本实施例中，第二谐振模式b的谐振频率、第三谐振模式c的谐振频率、第四谐振模式d以及第五谐振模式e的谐振频率依次增加。
本实施例中，第二谐振模式b所支持的频段包括GPS频段、LTE-4G MHB频段、NR-5G MHB频段中的至少一者，例如，GPS-L1频段、B3频段、B1频段、N3频段、N1频段中的至少一者。举例而言，第二谐振模式b的谐振频率为1.7698GHz。第三谐振模式c所支持的频段包括Wi-Fi 2.4G频段、LTE-4G MHB频段、NR-5G MHB频段等中的至少一者，例如，Wi-Fi 2.4G频段、B7频段、B41频段、B38频段、N7频段、N41频段等。举例而言，第三谐振模式c的谐振频率为2.6185GHz。所支持的频段包括LTE-4G UHB频段、NR-5G UHB频段等中的至少一者，例如，N78频段、B42频段、B43频段等中的至少一者。第四谐振模式d所支持的频段包括NR-5G UHB频段。举例而言，第四谐振模式d的谐振频率为3.5983GHz。其中，MHB是指中高频段(1000MHz至3000MHz)。UHB是指超高频段(3000MHz至10000MHz)。第五谐振模式e支持的频段为N77频段和N78频段中的至少一个。其中，每个谐振模式所覆盖的频段可以为某一频段中部分频段或全部频段，例如，可以对LTE 4G频段的全覆盖，或者，对LTE 4G频段的部分覆盖。
需要说明的是，以上从波长模式的角度说明第一谐振模式a至第五谐振模式e是一种比较好理解的解释，说明了各模式主要特征表象，易于区分。但各模式工作时，第一天线单元10、第二天线单元20并不是独立的，而是存在相互耦合，电流也会通过耦合流向对方。
可以理解的，在第二天线单元20中，第一辐射体11类似于第二辐射体21的寄生辐射体。第三谐振模式c和第五谐振模式e为第二馈电模块23激励寄生辐射体(第一辐射体11)而产生的谐振模式。
通过对第一辐射体11的长度、第一馈电点A至第一耦合端111之间的长度进行设计，以使第二馈电模块23能在第一辐射体11上的第一馈电点A至第一耦合端112之间以及接地点至第一耦合端112之间皆激励起谐振模式，提高第二天线单元20所能够支持的谐振模式的数量，有效地提高第二天线单元20所覆盖的频段数量、频段宽度等，提高天线组件100传输数据速率。
本实施方式中，第一匹配模块M1设于第一馈电点A与第一馈电模块13之间，用于对第一馈电模块13馈入的信号进行选频，例如，第一匹配模块M1从第一馈电模块13所发射的射频信号中选择小于1GHz的频段传送第一馈电点A。此外，第一匹配模块M1还能够对于第一天线单元10所支持的谐振模式进行调谐，以使天线组件100在所需支持的频段处进行谐振，及隔离第二天线单元20的谐振信号，增加第一天线单元10与第二天线单元20之间的隔离度。

其中，第二子支路151(L11、C11)和第三子支路152(L12)用于第二天线单元所支持的谐振模式对应的频段。举例而言，L21＝13nH，C21＝0.3pF，L22＝2.7nH，上述的第二子支路151和第三子支路152对于第一谐振模式所支持的谐振模式对应的频段呈低阻抗或带通，以导通第一谐振模式所a支持的频段，还能够有效地过滤掉除第一谐振模式a所支持频段之外的其他频段，进而减小第一天线单元10所支持的频段信号对于第二天线单元20的影响。第一子支路L13对第一谐振模式a所支持的频段起到调谐作用，并对第一谐振模式a所支持的频段起到隔离作用，以减少第一天线单元10所支持的信号对于第二天线单元20的影响。

以上仅仅为第二匹配模块M2的一种实施方式举例，在其他实施方式中，可以在第四子支路161与第二馈电点B之间增加支路，或者在第四子支路171与第二馈电点B之间增加支路。
其中，结合参考图6及图10，第四子支路161(C11)还能隔离第一天线单元10中的低频频段，以防止对第二天线单元20产生干扰，提高第一天线单元10和第二天线单元20的隔离度。第四子支路161、第六子支路163及第八子支路172用于第四谐振模式d。第五子支路162和第七子支路171用于调谐第二谐振模式b。一些示例性实施例中，第四子支路161(C11)用于第四谐振模式d的谐振点，以使第四谐振模式覆盖所支持的频段，此外，第六子支路163(C23)及第五子支路172(L22)皆能够调谐第四谐振模式d。举例而言，C11＝1pF，L11＝4.3nH，C12＝1pF，C13＝0.5pF，L12＝3.3nH，以使第二谐振模式b能够高效地支持LTE/NR-MHB，第三谐振模式c高效地支持WIFI 2.4G，第四谐振模式d高效地支持N41频段，第五谐振模式e高效地支持N78频段。
请结合参阅图11，第二匹配模块M2还包括至少一个电连接至第四参考地GND4的可调支路T。本申请对于可调支路T的位置不做限定，该可调支路T可为第四子支路161、或第五子支路162、或第六子支路163、或新增在第二馈电点B与第四子支路161之间、或新增在第四子支路161与第五子支路162之间、或新增在第六子支路163与第四子支路144之间等。可调支路T用于调谐第三谐振模式c的谐振频率。一些示例性实施例中，可调支路T用于调节第二谐振模式b的谐振频点的位置和第四谐振模式d的谐振频点的位置，以使扩展第二谐振模式b和第四谐振模式d支持所需的频段范围，例如，设有可调支路T的第二匹配模块M2将第二谐振模式b的谐振频率从1.77GHz移动至1.92GHz，将第四谐振模式d的谐振频率从3.6GHz移动至3.7GHz，如此，实现了天线组件100所能够支持的频段范围。
本申请对于可调支路T的具体结构不做限定。可选的，可调支路T包括开关电路、可调电容中的至少一者。其中，开关电路包括但不限于为多个开关+电容的支路、开关+电阻的多个支路、开关+电感的多个支路、开关+电感+电容的多个支路等。
举例而言，请结合参阅图11，可调支路T为第四支路17的一部分。一些示例性实施例中，可调支路T包括开关及多个并联设置的不同电感值的电感器件。
请结合参阅图12，L211的电感值为4.3nH，L212的电感值为3nH。该开关包括但不限于“单刀多掷”或“多刀多掷”开关。当开关导通L211至第二匹配模块M2中时，第二谐振模式b的谐振频率为1.77GHz，第三谐振模式c的谐振频率为3.6GHz；当开关导通L112至第二匹配模块M2中时，第二谐振模式b的谐振频率为1.92GHz，第三谐振模式c的谐振频率为3.7GHz。
在第二匹配模块M2设有可调支路T的情况下，本实施方式还通过对第二馈电点B的位置进行设计等方式，使可调支路T在对第二谐振模式b和第四谐振模式d进行调谐的同时，但是不会影响到或较少的影响到第三谐振模式c、第五谐振模式e，从而确保第二匹配模块M2能够调谐第二谐振模式b和第四谐振模式d，以增加天线组件100可支持的LTE 4G/NR 5G频段范围、提升各个频段的性能的同时，可以确保天线组件100保持能够支持WiFi 2.4G、WiFi 5G、WiFi 6E信号。
根据上述对于第二谐振模式b、第三谐振模式c、第四谐振模式d和第五谐振模式e在第一辐射体11和第二辐射体21上的谐振的波长模式分析，可知，第二馈电点B处的调谐对于第三谐振模式c、第五谐振模式e的谐振影响相对较小，对于第二谐振模式b和第四谐振模式d的谐振影响相对较大。
对于第二谐振模式b而言，第二辐射体21的电流密度分布从第二耦合端212至第二接地端211为先增加后减小再增加(例如图11中的虚线处)，其中，第二辐射体21的电流强点位于从第二耦合端212至第二接地端211的长度的1/3左右。第二馈电点B与第二接地端211之间的长度为第二辐射体11长度的(1/3至1)倍。可选的，第二馈电点B位于第二辐射体21的电流强点的位置或电流强点附近。
通过设置第二馈电点B位于第二辐射体21的电流强点的位置或电流强点附近。第二馈电点A与第二接地端211之间的长度为第二辐射体21长度的(1/3至1)倍。第二馈电点B与第二耦合端212之间的长度为第二辐射体21长度的1/3倍附近，以使第二馈电点B位于电流较强的位置。当第二馈电点B位于电流较强的位置时，第二匹配模块M2中设置可调支路T，该可调支路T对于第四谐振模式d的影响相对较小。当第一馈电点A位于第一辐射体11的电流强点的位置或电流强点附近，并将可调支路T中的L111切换至L112，从图中可以看出第四谐振模式d和第五谐振模式e的谐振点的位置不变，如此，实现了增加天线组件100可支持的LTE 4G/NR 5G频段范围的同时，可以确保天线组件100保持能够支持WiFi信号，以使天线组件100始终能够支持LTE 4G/NR 5G及WiFi信号。
本实施方式中，第二匹配模块M2设于第二馈电点B与第二馈电模块23之间，用于对第二馈电模块23馈入的信号进行选频，例如，第二匹配模块M2从第二馈电模块23所发射的射频信号中选择1GHz至4.5GHz的频段传送第二馈电点B。此外，第二匹配模块M2还能够对于第二天线单元20所支持的谐振模式进行调谐，以使天线组件100在所需支持的频段处进行谐振；及隔离第一天线单元10的谐振信号，增加第一天线单元10与第二天线单元20之间的隔离度。
以下结合附图对于第二匹配模块M2进行说明。
从图4和图6所示的第一天线单元10和第二天线单元20之间的隔离曲线，可以看出，0至7GHz所对应的隔离度的值位于-25以下，而显示在图示中的隔离度的值也位于-15以下，说明第一天线单元10和第二天线单元20之间具有较高的隔离度。通过上述第一匹配模块M1和第二匹配模块M2的设计，以使第一天线单元10和第二天线单元20具有较高的隔离度，利于提高第一天线单元10、第二天线单元20各自收发天线信号的效率。从图4可以看出，在第一匹配模块M1中设置可调支路T之后，第一天线单元10和第二天线单元20之间仍具有较高的隔离度。
以上为第一种实施方式提供的天线组件100，该天线组件100中包括相耦合的第一天线单元10和第二天线单元20，实现了低频/LTE 4G/NR 5G/WiFi信号共口径设计；天线组件100同时支持多种谐振模式，通过载波聚合技术实现了超带宽设计，同时，天线组件100可支持LTE 4G/NR 5G的双连接技术；其中，本申请通过对第一辐射体11长度、第一馈电点A的位置以及第二辐射体21的长度进行合理的设计，以使第一天线单元10单独支持低频频段，第二天线单元支持LTE 4G/NR 5G中高频及超高频、WiFi 2.4G频段，无需设置合路器等器件，以减少第二天线单元20的损耗，提高天线组件100的辐射效率。

请参阅图14，图14中两侧的虚线框为手指的握持区。当用户横屏握持电子设备1000(例如横屏玩游戏、看视频等)时，用户的双手的握持位置相对远离第一侧边框2103的中间位置，如此，使得第一耦合缝隙140远离用户的手持位置。当用户的手指越靠近天线组件100的电场强点(第一耦合缝隙140处)，对于天线组件100的干扰影响越大。因此，通过将天线组件100设于第一侧边框2103，并使得第一耦合缝隙140远离用户横屏握持电子设备1000的手持位置，以使用户在横屏握持电子设备1000玩游戏等场景时，第一耦合缝隙140避开用户的手指，使其不被遮挡。可选的，第一耦合缝隙140的位置与顶边框2101或底边框2102之间的距离为40mm以上，以使第一天线单元10和第二天线单元20仍具有较高的辐射效率，进而提高用户对于电子设备1000的使用体验。
当然，在其他实施方式中，请参阅图15，天线组件100的数量为多个，例如，两个天线组件100分别位于第一侧边框2103和第二侧边框2104。这两个天线组件100的结构、所支持的频段可以相同或不同。当这两个天线组件100皆具有耦合缝隙时，将这两个天线组件100的耦合缝隙分别设于或靠近第一侧边框2103、第二侧边框2104的中间位置，以减少用户横屏握持时对于天线组件100的遮挡，减少对于天线组件100的效率的影响。同时，两个天线组件100可以相互切换，实现电子设备1000能够在更多频段进行通讯或更宽的带宽下进行通讯，提高电子设备1000的通讯质量。
当然，在其他实施方式中，请参阅图16，天线组件100的第一辐射体11、第二辐射体21可以集成于顶边框210靠近拐角处，或者电子设备1000上的其他任意位置。

可选的，请参阅图17及图18，第一辐射体11和第二辐射体12设于第一侧边框2103，以在电子设备1000被横屏使用时，第一耦合缝隙140远离用户的手部，从而增加在横屏使用电子设备1000时的辐射效率。第三辐射体31设于第一侧边框2103和顶边框2101之间的拐角部2106，由于拐角部2106具有相对较好的净空区域，且拐角部2106更容易激励起较高的参考地电流，以提高第三天线单元30的辐射效率。本申请对于第三天线单元30所覆盖的频段不做限定。可选的，第三天线单元30可覆盖(GPS-L1)+(WIFI 2.4G)+(LTE/NR-MHB+UHB)。第三天线单元30的结构和尺寸可参考第二天线单元20的结构和尺寸。
可选的，请参阅图19，在第二接地端211与第三接地端311之间增加导电体将第二辐射体21与第三辐射体31连接起来。当第一辐射体11、第二辐射体21及第三辐射体31皆集成于边框210上时，第二辐射体21与第三辐射体31之间可不做切断，即将边框210的一部分作为第二辐射体21，将边框210的另一部分作为第三辐射体31。换言之，第二辐射体21与第三辐射体31形成共体辐射体32。
可选的，请参阅图20，天线组件100还包括第四匹配模块M4。第四匹配模块M4的一端电连接于第二接地端211，第四匹配模块M4的另一端电连接至第二参考地GND2。其中，第四匹配模块M4对第一天线单元10、第二天线单元20中需要在第二接地端211回地的谐振模式(例如第二谐振模式b)所支持频段呈低阻抗状态，例如，第四匹配模块M4为电感，以使需要在第二接地端211回地的谐振模式的谐振电流回地。
可选的，请参阅图20，天线组件100还包括第五匹配模块M5。第五匹配模块M5的一端电连接于第三接地端311，第五匹配模块M5的另一端电连接至第五参考地GND5。第五匹配模块M5对第三天线单元30中需要回地的谐振模式所支持频段呈低阻抗状态，例如，第五匹配模块M5为电感，以使第三天线单元30中需要在第三接地端311回地的谐振模式的谐振电流回地。
本实施方式中，天线组件100包括第四匹配模块M4和第五匹配模块M5，在其他实施方式中，天线组件100可仅包括第四匹配模块M4或仅包括第五匹配模块M5。
请参阅图21，定义第二辐射体21和第三辐射体31电连接之后为共体辐射体32。当共体辐射体32还作为检测待测主体(例如，人体的头部、手部等)接近的感应电极时，第四匹配模块M4包括直接电连接第二接地端211的容性器件或在第四匹配模块M4与第二接地端211之间设置容性器件；第五匹配模块M5包括直接电连接第三接地端311的容性器件或在第五匹配模块M5与第三接地端311之间设置容性器件；第二匹配模块M2包括直接电连接第二馈电点B的容性器件或在第二馈电点B与第二匹配模块M2之间设置容性器件；第三匹配模块M3包括直接电连接第三馈电点C的容性器件或在第三馈电点C与第三匹配模块M3之间设置容性器件；其中，容性器件例如电容、或包括电容的电路等，容性器件使得共体辐射体32相对于直流电流呈“悬浮状态”，以隔离待测主体靠近时产生的感应信号影响到天线信号。
可选的，第四匹配模块M4、第五匹配模块M5包括开关选择电路，例如，并联设置的电感支路和电容支路。当共体辐射体32需要检测人体靠近时，则控制开关导通电容与第二接地端211；当共体辐射体32不需要检测人体靠近时，则控制开关导通电感与第二接地端211。
可选的，第四匹配模块M4、第五匹配模块M5还包括电容和电感的支路。其中，电容电连接于第二接地端211与电感之间，电容使得共体辐射体32相对于直流电流呈“悬浮状态”，而电容和电感的支路对于需要从第二接地端211、第三接地端311回地的谐振模式所对应的频段呈低阻态。
请参阅图21，第四匹配模块M4、第五匹配模块M5用于隔直匹配，从而共体辐射体32可以作为SAR(比吸收率)检测部分。可选的，在第二匹配模块M2、第三匹配模块M3、第四匹配模块M4、第五匹配模块M5前分别加入隔直电容C31/C32/C33/C34(电容值例如为22pF，对天线信号基本无影响)，如果第一匹配模块M1、第二匹配模块M2、第四匹配模块M4、第五匹配模块M5中本身就有隔直电容，则不需要额外加C31/C32/C33/C34。此时，共体辐射体32对于感应信号来说是悬浮的，接近传感器需要有悬浮的金属体，来感应人体靠近带来的电容变化，从而达到检测的目的。在C33前加入检测电路，检测电路中加入电感L隔离较高频率(例如电感为82nH)，使天线基本不受影响。检测电路可以放在C31/C32/C34前，或天线辐射体的任意位置。通过在天线辐射体上的人体检测，判断人体靠近状态，从而达到智能降SAR的目的。
以上为共体辐射体32作为感应电极的实施方式，在其他实施方式中，第一辐射体11也能够作为感应电极，在后续以第三实施方式提供的天线组件100为例进行具体说明。

本实施方式中，第三辐射体31与第四辐射体41相互耦合，以使第四馈电模块43发送的激励电流不仅能够在第四辐射体41上形成谐振，还能够在第三辐射体31上形成谐振，及第三馈电模块33发送的激励电流不仅能够在第三辐射体31上形成谐振，还能够在第四辐射体41上形成谐振，以增加第三天线单元30和第四天线单元40所产生的谐振模式，进而增加第三天线单元30和第四天线单元40所支持的带宽、频段数量。
可选的，第三辐射体31和第四辐射体41可共同作为第三天线单元30的辐射体，第三辐射体31和第四辐射体41还可共同作为第四天线单元40的辐射体，以使第三天线单元30和第四天线单 元40形成共口径天线，以实现辐射体的复用，在增加谐振模式的数量的同时减小第三天线单元30和第四天线单元40的辐射体的堆叠尺寸。
可选的，第一辐射体11与第三辐射体31之间电连接。第一天线单元10、第二天线单元20、第三天线单元30及第四天线单元40形成共口径天线。

第十谐振模式j为第三馈电模块33的激励电流谐振于第三馈电点C至第一自由端312的1/8至1/4波长模式，及谐振于第二自由端412至第四接地端411的1/8至1/4波长模式。
一般地，通过设计第三馈电点C至第一自由端312的长度约为第三馈电模块33发送至第三馈电点C至第一自由端312的激励电流在介质中的波长的1/4倍，及通过设计第二自由端412至第四接地端411的长度约为第三馈电模块33发送至第二自由端412至第四接地端411的激励电流在介质中的波长的1/4倍，在第十谐振频点(第十谐振模式j的谐振频率)易激励起较高的辐射效率。通过在第三馈电点C至第一自由端312的路径上设置接地的容性的匹配电路，及在第二自由端412至第四接地端411的路径上设置接地的容性的匹配电路，容性加载皆可使得第十谐振模式j的谐振频率朝向低频偏移，不再遵循原本的需要在第三馈电点C至第一自由端312的长度约为1/4波长处、第二自由端412至第四接地端411的长度约为1/4波长处产生较高效率的谐振，而是可以在第三馈电点C至第一自由端312的长度对应1/8至1/4波长的范围内，及第二自由端412至第四接地端411的长度对应1/8至1/4波长的范围内，能够产生较高效率的谐振，故在原来的第十谐振频点形成谐振的同时还能够使所对应的第三馈电点C至第一自由端312的长度缩短及使得第四辐射体41的长度缩短，例如，减小至第十谐振频点对应的波长的1/8倍等，减小第三辐射体31、第四辐射体41的尺寸，减小天线组件100的堆叠长度。

一般地，通过设计第四馈电点D至第二自由端412的长度约为第四馈电模块43发送的激励电流在介质中的波长的1/4倍，此时，在第十一谐振频点处(即第十一谐振模式k的谐振频率)易激励起较高的辐射效率。通过在第十一谐振电流的路径上设置接地的容性的匹配电路，以实现容性耦合馈入第四辐射体41上，容性加载皆可使得第十一谐振模式k的谐振频率朝向低频偏移，不再遵循原本的需要在第四馈电点D至第二自由端412的长度约为1/4波长处产生较高效率的谐振，而是可以在第四馈电点D至第二自由端412的长度对应1/8至1/4波长的范围内，能够产生较高效率的谐振，故在原来的第十一谐振频点f11形成谐振的同时还能够使所对应的第四馈电点D至第四接地端412的长度缩短，例如，减小至第十一谐振频点f11对应的波长的1/8倍等，减小第四馈电点D至第二自由端412的尺寸，减小天线组件100的堆叠长度。
请参阅图26C，第十二谐振模式l的第十二谐振电流密度主要分布于第三接地端311至第一自由端312之间，从第三接地端311流向第一自由端312，或者从第一自由端312流向第三接地端311。可以理解的，上述为第十二谐振模式l的主要的电流密度分布，在第二自由端412与第四接地端411之间也具有少量的电流密度分布。

需要说明的是，以上从波长模式的角度说明第七谐振模式g至第十二谐振模式l是一种比较好理解的解释，说明了各模式主要特征表象，易于区分。但各模式工作时，第三天线单元30、第四天线单元40并不是独立的，而是存在相互耦合，电流也会通过耦合流向对方。
第三辐射体31在所述第三馈电模块33的激励下(即所述第三天线单元30)支持的频段包括GPS频段、Wi-Fi 2.4G频段、LTE-4G MHB频段、NR-5G MHB频段、LTE-4G UHB频段、NR-5G UHB频段。举例而言，第七谐振模式g、第八谐振模式h、第九谐振模式i的谐振频率分别为1.5766GHz、2.4667GHz、2.9773GHz。第三天线单元30覆盖(GPS-L1)+(WIFI 2.4G)+(LTE/NR-MHB+UHB)。在其他实施方式中，第三天线单元30覆盖(GPS-L1)+(WIFI2.4G)+(LTE/NR-MHB+UHB)+N77/N78。

当用户横屏使用电子设备1000时，第一耦合缝隙140避开了手部所握持的位置，以使第一天线单元10和第二天线单元20的辐射效率较高，进而收发低频+(GPS-L1)+(WIFI 2.4G)+(LTE/NR-MHB+UHB)+N77/N78+Wi-Fi 5G/Wi-Fi 6E频段，提高横屏使用体验。当用户竖屏使用电子设备1000时，第二耦合缝隙150避开了手部所握持的位置，以使第三天线单元30和第四天线单元40的辐射效率较高，进而收发(GPS-L1)+(WIFI 2.4G)+(LTE/NR-MHB+UHB)+N77/N78+Wi-Fi 5G/Wi-Fi 6E频段，提高竖屏使用体验。由上可知，本实施方式提供的天线组件100满足在横屏和竖屏下皆能够高效地覆盖(GPS-L1)+(WIFI 2.4G)+(LTE/NR-MHB+UHB)+N77/N78+Wi-Fi 5G/Wi-Fi 6E频段。

可以理解的，上述的第一匹配模块M1至第五匹配模块M6内皆可以设置图9A至图9H中任意一实施方式的器件，也可包括开关电路、可变电容等可调器件。

一些示例性实施例中，请参阅图29A，天线组件100还包括隔直组件70、过滤组件50、检测组件80及控制器(未图示)。
以下结合第三种实施方式提供的天线组件100，对隔直组件70、过滤组件50的连接方式进行举例说明。
请参阅图29A，第一种接近检测的实施方式中，共体辐射体32作为用于感应待测主体靠近时的感应电极。隔直组件70电连接于所述第二馈电点B与所述第二匹配模块M2之间、所述第二接地端111与所述第二参考地GND2之间(当第二接地端211与第二参考地GND2之间设有第四匹配模块M4时，隔直组件70设于第二接地端211与第四匹配模块M4之间)、所述第三接地端311与所述第五参考地GND5之间(当第三接地端311与第五参考地GND5之间设有第五匹配模块M5时，隔直组件70设于第三接地端311与第五匹配模块M5之间)、及所述第三馈电点C与所述第三匹配模块M3之间。隔直组件70用于阻隔第二匹配模块M2、第二参考地GND2、第五参考地GND5、第三匹配模块M3所产生的直流电流，以支持人体检测功能，提高人体靠近天线组件100时的检测准确性。
所述过滤组件50的一端电连接所述隔直组件70靠近于所述共体辐射体32的一侧或电连接所述共体辐射体32的任意位置。所述过滤组件50用于阻隔所述共体辐射体32收发的射频信号及通过所述共体辐射体32在待测主体靠近时产生的感应信号，以使第二辐射体21收发的射频信号不会影响到检测组件80检测感应信号的检测准确性。
一些示例性实施例中，请参阅图29A，隔直组件70包括第一子隔离器71、第二子隔离器72、第三子隔离器73及第四子隔离器74。第一子隔离器71电连接于第二接地端211与第二参考地GND2(具体为第二接地端211与第四匹配模块M4)之间。第二子隔离器72电连接于第二馈电点B与第二匹配模块M2之间。第三子隔离器73电连接于第三接地端311与第五参考地GND5(具体为第三接地端311与第五匹配模块M5)之间。第四子隔离器74电连接于第三馈电点C与第三匹配模块M3之间。
通过设置隔直组件70，以使待测主体靠近共体辐射体32时所产生的感应信号不会影响到天线组件100对于天线信号的收发。一些示例性实施例中，第一子隔离器71、第二子隔离器72、第三子隔离器73及第四子隔离器74皆为容性器件。举例而言，第一子隔离器71、第二子隔离器72、第三子隔离器73及第四子隔离器74皆为电容器，第一子隔离器71、第二子隔离器72、第三子隔离器73及第四子隔离器74对天线组件100所支持的射频信号呈小阻抗到地，例如，第一子隔离器71、第 二子隔离器72、第三子隔离器73及第四子隔离器74的值包括但不限于为47pF或22PF等。第一子隔离器71对第四匹配电路M4的直流电流具有隔离作用，第二子隔离器72对第二匹配电路M2的直流电流具有隔离作用，第三子隔离器73对第五匹配模块M5具有隔离作用，第四子隔离器74对第三匹配模块M3具有隔离作用，以支持人体检测功能，提高人体靠近天线组件100时的检测准确性。换言之，隔直组件70使得共体辐射体32相对于直流电流呈“悬浮”状态。
一些示例性实施例中，过滤组件50电连接于第一子隔离器71与第二接地端112之间；或，电连接于第二子隔离器72与第二馈电点B之间；或，电连接于第三子隔离器73与第三接地端311之间；或，电连接于第四子隔离器74与第三馈电点C之间；或，电连接于共体辐射体32的任意位置。过滤组件50包括电感器件或为电感器件。例如，过滤组件50为电感。过滤组件50对于天线组件100所支持的射频信号呈大阻抗，电感值例如82nH。
以上隔直组件70和过滤组件50实现了感应信号及射频信号可同时作用且互不干扰。
检测组件80电连接过滤组件50的另一端，检测组件80用于检测辐射体产生的感应信号的大小。可选的，检测组件80为用于检测电流信号、电压信号或电感信号的器件，例如微型检流计、微型电流互感器、电流比较器、电压比较器等等。
人体皮肤表面靠近共体辐射体32时，人体皮肤表面与共体辐射体32可分别等效为电容器的两个电极板。当人体的头部靠近时，共体辐射体32可感应人体的头部带来的电荷量的变化。过滤组件50电连接共体辐射体32。上述的电荷量变化形成感应信号，该感应信号经过滤组件50传输至检测组件80。根据电容计算公式，C＝εS/4πkd，其中，d是人体(头部或者手部)与辐射体之间距离，所以当电容增加，即检测组件80所检测到的感应信号的强度增加时，说明人体在靠近；当电容减小，即检测组件80所检测到的感应信号的强度减小时，说明人体在远离。检测组件80通过检测上述的感应信号的变化，以判断人体的头部是否靠近于天线组件100的共体辐射体32，从而智能降低人体头部对电磁波的比吸收率。
可选的，隔直组件70的至少部分还能够作为匹配模块的一部分，例如第二子隔离器72为电容器，第二子隔离器72用于阻隔感应信号，及导通射频信号的同时，还能够作为第二匹配模块M2的一部分，用以调谐信号源21与第二馈电点B之间的阻抗匹配，以减小馈入共体辐射体32的射频信号的损耗，提高共体辐射体32收发的信号转换效率；还用于调节共体辐射体32上产生的谐振模式的频偏等等，实现了器件的一物多用，减少器件数量和占据的空间，提高器件的集成度。
当第二匹配模块M2电连接第二馈电点B的部分为电容器，则无需再设置第二子隔离器72。同样地，当第四匹配模块M4电连接于第二接地端211的部分为电容器，则无需再设置第一子隔离器71。当第五匹配模块M5电连接于第三接地端311的部分为电容器，则无需再设置第三子隔离器73。当第三匹配模块M3电连接于第二馈电点B的部分为电容器，则无需再设置第四子隔离器74。
本申请提供的天线组件100及电子设备1000，通过复用天线组件100上的共体辐射体32为检测人体等待测主体靠近的感应电极，并通过隔直组件70、过滤组件50对感应信号和射频信号进行分隔，实现了天线组件100的通信性能和感应待测主体的双重作用，增加天线组件100的功能，提高器件利用率，减小电子设备1000的整体体积。
本实施方式一方面可以增加接近感应面积，另一方面，由于共体辐射体32设于第一侧边框2103、顶边框2101上及第一侧边框2103及顶边框2101上的拐角部2106，将共体辐射体32作为感应电极，可检测到电子设备1000的前、后、第一侧边框2103的朝向侧、顶边框2101的朝向侧的待测主体的接近感应，增加SAR检测范围。
第二种接近检测的实施方式中，请参阅图29B，第二辐射体21作为检测待测主体靠近的感应电极。
隔直组件70电连接于第一辐射体11的第一接地端111与第一参考地GND1之间、所述第一匹配模块M1与所述第一馈电点A之间。隔直组件70的具体结构和隔离感应信号、导通射频信号的原理可参考第一种隔直组件70、过滤组件50的连接方式，在此不再赘述。过滤组件50的一端电连接隔直组件70靠近第一辐射体11的一侧(例如隔直组件70与第一接地端111之间)或电连接第一辐射体11的任意位置。所述隔直组件70用于阻隔第一参考地GND1、所述第一匹配模块M1所产生的直流电流，所述过滤组件50用于阻隔所述第一辐射体11收发的射频信号及通过所述第一辐射体 11在待测主体靠近时产生的感应信号；本实施方式中，第一辐射体11为感应电极，第一辐射体11相对于直流电流呈悬浮状态。
第三种接近检测的实施方式中，请参阅图29C，第四辐射体41作为检测待测主体靠近的感应电极。隔直组件70电连接于所述第四接地端411与所述第六参考地GND6之间、所述第六匹配模块M6与所述第四馈电点D之间，所述过滤组件50的一端电连接所述隔直组件70靠近所述第三辐射体31的一侧或电连接所述第三辐射体31；所述隔直组件70用于阻隔第六参考地GND6、第六匹配模块M6所产生的直流电流，所述过滤组件50用于阻隔所述第三辐射体31收发的射频信号及通过所述第四辐射体41在待测主体靠近时产生的感应信号。
可以理解的，第一种接近检测的实施方式、第二种接近检测的实施方式、第三种接近检测的实施方式可以选择其中一者进行实施，可以选择其中两者进行实施，可以选择其中的三者进行实施。
以下对于第一种接近检测和第三种接近检测同时实施的实施方式进行说明。
请参阅图29D，在第一种接近检测的基础上，隔直组件70还包括第五子隔直器75及第六子隔直器76。其中，第五子隔直器75电连接于第四馈电点D与第六匹配模块M6之间，第六子隔直器76电连接于第四接地端411与第六参考地GND6之间，以使共体辐射体32、第四辐射体41皆能够作为感应待测主体接近的感应电极。
请参阅图29D，过滤组件50包括第一子过滤器51及第二子过滤器52。其中，第一子过滤器51电连接于第一子隔离器71与第二馈电点B之间、或第二子隔离器72与第二接地端211之间、第三子隔离器73与第三接地端311之间、或第四子隔离器74与第三馈电点C之间、或共体辐射体32的任意位置。第二子过滤器52电连接第五子隔直器75与第四馈电点D之间、第六子隔直器76与第四接地端411之间、或第四辐射体41的任意位置。
一些示例性实施例中，第一子隔离器71、第二子隔离器72及第三子隔离器73皆为隔离电容，第一子过滤器51及第二子过滤器52皆为隔离电感。
请参阅图29D，检测组件80电连接第一子过滤器51及第二子过滤器52。一些示例性实施例中，检测组件80的两个通道分别电连接第一子过滤器51及第二子过滤器52。本实施方式中，共体辐射体32、第四辐射体41皆能够作为感应待测主体靠近的检测电极。
在其他实施方式中，检测组件80包括第一子检测器及第二子检测器。第一子检测器电连接第一子过滤器51的另一端，第二子检测器电连接第二子过滤器52的另一端。换言之，通过两个相互独立的子检测器分别检测共体辐射体32、第四辐射体41所检测到的感应信号，此实施方式可使用于共体辐射体32、第四辐射体41分别位于电子设备1000的不同侧时，通过一个天线组件100的辐射体即可检测电子设备1000来自不同侧的人体接近，进而实现在占据较小的空间的情况下提高检测范围。
当人体靠近共体辐射体32时，共体辐射体32上的电荷变化，检测组件80通过第一子过滤器51直接可以感应到感应信号；当人体靠近第四辐射体41时，第四辐射体41上的电荷变化，检测组件80通过第二子过滤器52直接可以感应到感应信号。检测组件80通过检测感应信号以检测人体接近，此情况下能够将所有辐射体皆作为感应电极，以使感应面积较大，可提高辐射体的利用率，只需一个检测组件80，可节省天线组件100的器件数量及节省空间。
控制器电连接检测组件80。检测组件80接收感应信号并转化成电信号并传输至控制器。控制器用于根据感应信号的大小检测待测主体与辐射体之间的距离，进而判断人体是否接近辐射体，并在待测主体与辐射体之间的距离小于或等于预设距离值时调节第一馈电模块13(或者调节第三馈电模块33、调节第四馈电模块43)的功率。一些示例性实施例中，控制器根据不同的场景可以对天线组件100的功率进行调节，以实现智能减小人体对于电磁波信号的比吸收率。
举例而言，当人体头部靠近天线组件100的辐射体时，控制器可降低天线组件100的功率，以降低天线组件100所辐射电磁波的比吸收率。当人体手部在辐射方向上遮挡天线组件100的辐射体时，在电子设备1000内还设有其他备用天线组件100(即能够覆盖相同频段的天线组件100)的情况下，控制器可关闭被遮挡的天线组件100，及开启其他位置未被遮挡的天线组件100，如此，在人体手部遮挡天线组件100时，通过智能切换天线组件100，可确保电子设备1000的通信质量；在电子设备1000内未设置其他备用的天线组件100的情况下，控制器可控制天线组件100的功率增加， 以补偿手部遮挡辐射体后导致的效率降低的问题。
当然，控制器还根据检测组件80的检测结果控制电子设备1000上的其他应用程序，例如，控制器根据检测组件80的检测结果检测到人体靠近及电子设备1000处于通话状态，来控制显示屏300的屏幕亮度关闭，以节省电子设备1000在通话时的电能；控制器还根据检测组件80的检测结果检测到人体远离及电子设备1000处于通话状态，来控制显示屏300的屏幕亮度点亮。
当然，在其他实施方式中，第一种接近检测的实施方式、第二种接近检测的实施方式、第三种接近检测的实施方式可以一起实施。
可选的，当辐射体用于人体接近检测，且辐射体与边框210集成为一体时，可在辐射体表面设置一层绝缘膜，由于人体皮肤表面具有电荷，人体皮肤表面与辐射体之间形成电容结构，进而通过辐射体感应人体皮肤表面接近带来的信号变化。
可选的，电子设备1000中可设置多个天线组件100，这些天线组件100为上述所述的任意一项实施方式所列举的天线组件100，多个天线组件100能够在不同的遮挡场景下实现智能切换工作，以实现在任意手持遮挡等情况下皆能够具有较高的天线收发效率，并且，多个天线组件100的辐射体集成检测功能后，可以检测不同的用户场景(例如单手握持、双手握持、随身携带状态、通话状态等等)，可以实现比吸收率(SAR)标准中6个面的检测。
可选的，请参阅图30，所述第二接地端121与所述第三接地端311之间为连接段。连接段上设有至少一个连接点(例如图31中的第一连接点511和图52中的第二连接点512)。天线组件100还包括至少一个第七匹配模块M7，第七匹配模块M7的一端电连接所述连接点(第一连接点511)，第七匹配模块M7的另一端电连接至第七参考地GND7。第七匹配模块M7能够有效地滤除第一天线单元10和第二天线单元20的射频信号，以避免该射频信号干扰至第三天线单元30和第四天线单元40。可选的，第七匹配模块M7包括对于第一天线单元10、第二天线单元20所支持的频段呈带通状态或小阻抗状态的接地电路，以使第一天线单元10、第二天线单元20与第三天线单元30、第四天线单元40之间的隔离度更好。此外，第七匹配模块M7还能够有效地滤除第三天线单元30和第四天线单元40的射频信号，以避免该射频信号干扰至第一天线单元10和第二天线单元20。可选的，第七匹配模块M7包括对于第三天线单元30、第四天线单元40所支持的频段呈带通状态或小阻抗状态的接地电路，以使第一天线单元10、第二天线单元20与第三天线单元30、第四天线单元40之间的隔离度更好。
此外，第七匹配模块M7可以滤除天线组件100中一些效率较低的工作模式，例如，电流从第二参考地GND2流向第二接地端211、第三接地端311、回流至第五参考地GND5的工作模式，以减小这些低效率的工作模式对于天线组件100的谐振模式的影响。
可选的，连接点(第一连接点511)的位置可靠近于第二接地端121或第三接地端311，以使第二接地端221和第三接地端311之间还能够设置按键。第七匹配模块M7与连接点相对。当然，在第二接地端221与第三接地端311之间无需设置按键时，连接点可以设于第二接地端221与第三接地端311之间的任意位置，包括但不限于第二接地端121与第三接地端311的中间位置。
可选的，请参阅图31，连接点的数量为多个，例如两个连接点(第一连接点511和第二连接512)分别靠近第二接地端121和第三接地端311。电连接所述连接点(第一连接点511和第二连接512)的匹配模块的数量为两个，分别记为第七匹配模块M7和第八匹配模块M8。第七匹配模块M7和第八匹配模块M8皆能够增加第一天线单元10、第二天线单元20与第三天线单元30、第四天线单元40之间的隔离度，并滤除天线组件100中一些效率较低的工作模式，提高天线组件100各个谐振模式的收发效率。本申请提供的天线组件100可实现四天线共口径设计，在增加收发频段的带宽和频段数量的同时，还能够减小天线组件100的堆叠空间，此外，在天线组件100的辐射体集成人体接近检测功能，能够智能检测人体靠近，进而减小比吸收率，或检测出电子设备1000的被握持状态、所处应用状态等，此外，通过对天线组件100在电子设备1000上的合理布局，以使电子设备1000在横屏使用状态下皆具有较高的信号收发效率。
以上所述是本申请的部分实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
