以下结合附图对于本申请提供的天线组件100进行具体的说明，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、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，第一耦合端112与第二耦合端211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0.5～2mm，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、构造不做具体的限定，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，也可以为宽度渐变、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。

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，也可以为天线组件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212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。
本实施例中，第一辐射体11和第二辐射体21在第一馈电模块13和第二馈电模块23的激励下支持多个谐振模式。具体的，第一辐射体11和第二辐射体21在第一馈电模块13的激励下支持多个谐振模式(例如，图4中的第一谐振模式a、第二谐振模式b和第三谐振模式c)。具体的，第一辐射体11和第二辐射体21在第二馈电模块23的激励下支持多个谐振模式(例如，图4中的第四谐振模式d及第五谐振模式e)。
由于第一辐射体11与第二辐射体21容性耦合，第一馈电模块13产生电流能够谐振于第一辐射体11和/或第二辐射体21上，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/或第二辐射体21，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，相较于第一馈电模块13产生的电流单独谐振于第一辐射体11上，以及第二馈电模块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，进一步减小的第一辐射体11和第二辐射体21的堆叠长度。
其中，至少一个谐振模式为第一馈电模块13的激励电流谐振于第二辐射体21上的(1/8～1/4)波长模式。其中，波长是指电磁波在所处环境中的介质中的波长。具体的，第一馈电模块13提供的电流谐振于第一辐射体11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，第一馈电模块13提供的电流还经第一耦合缝隙140传送至第二辐射体21上，以在第二辐射体21上产生谐振模式，增加第一天线单元10所支持的谐振模式数量；进一步地，通过设计第二辐射体21的长度约为第一馈电模块13提供的电流频率在介质中的波长的(1/8～1/4)倍，以利于产生谐振模式，使电流谐振于第二辐射体21上的(1/8～1/4)波长模式，其中，(1/8～1/4)波长模式为效率相对较高的谐振模式，故能够增加第一天线单元10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，实现第一天线单元10在第一辐射体11和第二辐射体21上皆产生谐振模式。相较于第一天线单元10的电流仅仅谐振于第一辐射体11上，增加了第一天线单元10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。具体的，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4G/5G中高频(例如1000MHz～3000MHz)和4G/5G超高频(例如3000MHz～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WiFi 5G、5.925GHz～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4G/5G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WiFi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，并设计第二辐射体21的长度与第一馈电模块13提供的激励电流的谐振频率的(1/8～1/4)波长相对应，使第一馈电模块13传送的电流谐振于第一辐射体11的同时，还能够通过第一耦合缝隙140谐振于第二辐射体21上的(1/8～1/4)波长模式，故能够增加第一天线单元10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，进而增加第一天线单元10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至少支持第一谐振模式a、第二谐振模式b及第三谐振模式c。
可选的，第一辐射体11在第一馈电模块13的激励下至少支持第一谐振模式a及第三谐振模式c。第二辐射体21在第一馈电模块13的激励下至少支持第二谐振模式b。
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。
请参阅图5，第一谐振模式a的第一谐振电流密度主要分布于第一接地端111与第一耦合端112之间，从第一接地端111流向第一耦合端112，或者从第一耦合端112流向第一接地端111。可以理解的，上述为第一谐振模式a的主要的电流密度分布，在第二辐射体21上也具有少量的电流密度分布。
具体的，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(1/8～1/4)波长模式。具体的，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(1/8～1/4)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。进一步地，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1/8～1/4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，进一步地减小第一辐射体11的尺寸，减小天线组件100的堆叠长度。
可选的，请参阅图6，第二谐振模式b的第二谐振电流密度主要分布于第一馈电点A与第二接地端212之间，从第一馈电点A流向第一耦合端112，经第一耦合缝隙140后再从第二耦合端211流向第二接地端212，或者从第二接地端212流向第二耦合端211，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，上述为第二谐振模式b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4及图6，第二谐振模式b为第一馈电模块13提供的激励电流(第二谐振电流)谐振于第二辐射体21上的(1/8～1/4)波长模式。具体的，通过设计第二辐射体21的长度约为第一馈电模块13发送至第二辐射体21的激励电流在介质中的波长的(1/8～1/4)倍，以在第二辐射体21上激励起第二谐振模式b。
一般地，通过设计第二辐射体21的长度约为第一馈电模块13发送的激励电流在介质中的波长的(1/4)倍，此时，在第二谐振频点f2(第二谐振模式b的谐振频率处)易激励起较高的辐射效率。进一步地，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1/8～1/4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，进一步地减小第二辐射体21的尺寸，减小天线组件100的堆叠长度。
可选的，请参阅图7，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，从第一馈电点A流向第一耦合端112，或者从第一耦合端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、第二辐射体21上也具有少量的电流密度分布。
请一并参阅图4及图7，第三谐振模式c为第一馈电模块13提供的激励电流(第三谐振电流)谐振于第一馈电点A至第一耦合端112的(1/8～1/4)波长模式。具体的，通过设计第一馈电点A至第一耦合端112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(1/8～1/4)倍，以在第一馈电点A至第一耦合端112上激励起第三谐振模式c。
一般地，通过设计第一馈电点A至第一耦合端112的长度约为第一馈电模块13发送的激励电流在介质中的波长的(1/4)倍，此时，在第三谐振频点f3处(第三谐振模式c的谐振频率)易激励起较高的辐射效率。进一步地，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馈电点A至第一耦合端112的长度约为1/4波长处产生较高效率的谐振，而是可以在第一馈电点A至第一耦合端112的长度对应1/8～1/4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馈电点A至第一耦合端112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，进一步地减小第一馈电点A至第一耦合端112的尺寸，减小天线组件100的堆叠长度。
当然，在其他实施方式中，第二谐振模式b为第一馈电模块13提供的激励电流谐振于第一馈电点A至第一耦合端112的(1/8～1/4)波长模式。第三谐振模式c为第一馈电模块13提供的激励电流谐振于第一馈电点A至第一耦合端112的(1/8～1/4)波长模式。
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，以使第一馈电模块13能在第一辐射体11、第一馈电点A与第一耦合端112之间的第一辐射体11上及第二辐射体21上皆激励起谐振模式，提高第一天线单元10所能够支持的谐振模式的数量，有效地提高第一天线单元10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。
可选的，第一谐振模式a、或第二谐振模式b、或第三谐振模式c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，第一谐振模式a的谐振频率的大小、第二谐振模式b的谐振频率的大小及第三谐振模式c的谐振频率的大小不做具体的限定。本实施例中，第一谐振模式a的谐振频率、第二谐振模式b的谐振频率及第三谐振模式c的谐振频率依次增加。当第一谐振模式a、第二谐振模式b及第三谐振模式c皆为1/4波长模式时，由于第一谐振模式a的谐振频率、第二谐振模式b的谐振频率及第三谐振模式c的谐振频率依次增加，可得到第一谐振模式a的谐振频率对应的1/4波长、第二谐振模式b的谐振频率对应的1/4波长及第三谐振模式c的谐振频率对应的1/4波长依次减小，而将第二谐振模式b的谐振频率对应的1/4波长的辐射部分设于第一辐射体11上，相较于将第三谐振模式c的谐振频率对应的1/4波长设于第一辐射体11上的共口径辐射体的总长度更短，实现了天线组件100的第一辐射体11和第二辐射体21的堆叠长度更短，进一步地减小天线组件100在空间极其有限的空间内所占据的空间。
本实施例中，第一谐振模式a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，第一谐振模式a的谐振频率为1.7698GHz。第二谐振模式b所支持的频段包括Wi-Fi 2.4G频段、LTE-4GMHB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，第二谐振模式b的谐振频率为2.6185GHz。第三谐振模式c所支持的频段包括LTE-4GUHB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。举例而言，第三谐振模式c的谐振频率为3.5983GHz。其中，MHB是指中高频段(1000MHz～3000MHz)。UHB是指超高频段(3000MHz～10000MHz)。
可选的，请参阅图4，第二辐射体21至少支持第四谐振模式d及第五谐振模式e。
可选的，第二耦合端211至第二馈电点B之间的第二辐射体21在第二馈电模块23的激励下至少支持第四谐振模式d。第一辐射体1121在第二馈电模块23的激励下至少支持第五谐振模式e。
可选的，请参阅图4及图8，第四谐振模式d的第四谐振电流密度主要分布于第二馈电点B至第二耦合端211之间，从第二馈电点B流向第二耦合端211，或者从第二耦合端211流向第二馈电点B。可以理解的，上述为第四谐振模式d的主要的电流密度分布，在第二接地端212与第二馈电点B之间、第一辐射体11上也具有少量的电流密度分布。
具体的，第四谐振模式d为第二馈电模块23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211的(1/8～1/4)波长模式。具体的，通过设计第二馈电点B至第二耦合端211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(1/8～1/4)倍，以在第二馈电点B至第二耦合端211上激励起第四谐振模式d。
一般地，通过设计第二馈电点B至第二耦合端211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(1/4)倍，此时，在第四谐振频点f4处(第四谐振模式d的谐振频率)易激励起较高的辐射效率。进一步地，通过在第四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四谐振模式d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211的长度约为1/4波长处产生较高效率的谐振，而是可以在第二馈电点B至第二耦合端211的长度对应1/8～1/4波长的范围内，能够产生较高效率的谐振，故在原来的第四谐振频点f4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211的长度缩短，例如，减小至第四谐振频点f4对应的波长的1/8倍等，进一步地减小第二馈电点B至第二耦合端211的尺寸，减小天线组件100的堆叠长度。
可选的，请参阅图9，第五谐振模式e的第五谐振电流密度主要分布于第一接地端111至第一耦合端112之间，从第一接地端111流向第一耦合端112，或者从第一耦合端112流向第一接地端111。可以理解的，上述为第五谐振模式e的主要的电流密度分布，在第二耦合端211与第二接地端212之间也具有少量的电流密度分布。
第五谐振模式e为第二馈电模块23的激励电流谐振于第一辐射体11的(3/4)波长模式。具体的，通过设计第一辐射体11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(3/4)倍，以在第一辐射体11上激励起第五谐振模式e。
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。第五谐振模式e为第二馈电模块23激励寄生辐射体(第二辐射体21)而产生的谐振模式。
通过对于第一辐射体11的长度、第二馈电点B至第二耦合端211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、第二馈电点B至第二耦合端211之间的第二辐射体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。
可选的，第四谐振模式d及第五谐振模式e所支持的频段包括GPS频段、或LTE 4G频段、或NR5G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，第四谐振模式d的谐振频率的大小、第五谐振模式e的谐振频率的大小不做限定。本实施例中，第四谐振模式d的谐振频率小于第五谐振模式e的谐振频率。
进一步地，第四谐振模式d的谐振频率大于第三谐振模式c的谐振频率。故第四谐振模式d的谐振 频率的1/4波长小于第三谐振模式c的谐振频率的1/4波长。在第二辐射体21中，通过合理设计第二馈电点B的位置，以使第二馈电点B与第二耦合端211之间的长度与第四谐振模式d的谐振频率的1/4波长相对应，进而在第二辐射体21的第二馈电点B与第二耦合端211之间激励起谐振模式。
当第五谐振模式e的谐振频率为第一谐振模式a的谐振频率的3～6倍(例如第一谐振模式a支持GPS-L1频段、B3频段、B1频段、N3频段、N1频段，第五谐振模式e支持Wi-Fi 5G频段、Wi-Fi 6E频段)时，第二馈电模块23可在第一辐射体11上激励起3/4波长模式，如此，在增加谐振模式数量的同时还复用了第一辐射体11。
以上，皆为在第一辐射体11和第二辐射体21上进行了合理的尺寸设计和馈电点的位置规划，以在第一辐射体11和第二辐射体21的有限长度上尽可能多的产生较高效率的谐振模式和支持所需的频段。
本实施例中，第四谐振模式d和第五谐振模式e所支持的频段皆包括Wi-Fi 5G频段、Wi-Fi 6E频段中的至少一者。举例而言，第四谐振模式d的谐振频率为5.4751GHz，第五谐振模式e的谐振频率为6.0064GHz。
本实施例中，第一天线单元10支持的频段覆盖GPS-L1频段、Wi-Fi 2.4G频段、LTE-4G MHB频段(B3频段、B1频段、B7频段、B41频段、B38频段)、NR-5G MHB频段(N3频段、N1频段、N7频段、N41频段)、LTE-4G UHB频段(B42频段、B43频段)、NR-5G UHB频段(N78频段)；第二天线单元20支持的频段覆盖Wi-Fi 5G频段、Wi-Fi 6E频段等，如此，使得第二天线单元20只需支持一种通信协议的通信信号，进而避免在第二天线单元20中的射频链路中设置合路器等器件将两种不同通信协议的通信信号合路，减少了射频链路中的器件，进而减少了天线组件100射频链路的损耗。
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1GHz～7GHz的频段传送第一馈电点A，或者，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1GHz～4.5GHz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。

以上仅仅为第一匹配模块M1的一种实施方式举例，在其他实施方式中，还可以在第一子支路141与第一馈电点A之间增加支路，或者在第四子支路151与第一馈电点A之间增加支路。
其中，结合参考图3、图4及图10，第一子支路141、第三子支路143及第五子支路152用于调谐第二谐振模式b和第三谐振模式c。第二子支路142和第四子支路151用于调谐第一谐振模式a。具体的，第一子支路141(C11)用于调谐第二谐振模式b、第三谐振模式c的谐振点，以使第三谐振模式c覆盖N 78频段，及使第二谐振模式b覆盖N41频段，此外，第一子支路141(C11)还能隔离第二天线单元20中的WIFI-5G、WIFI-6E频段，以防止WIFI-5G、WIFI-6E频段干扰第一天线单元10，提高第一天线单元10和第二天线单元20的隔离度。第三子支路143(C13)及第五子支路152(L12)皆能够调谐第二谐振模式b和第三谐振模式c。举例而言，C11＝1p F，L11＝4.3nH，C12＝1pF，C13＝0.5pF，L12＝3.3nH，以使第一谐振模式a能够高效地支持LTE/NR-MHB，第二谐振模式b高效地支持WIFI 2.4G、N41频段，第三谐振模式c高效地支持N78频段。
请结合参阅图19，第一匹配模块M1还包括至少一个电连接至第三参考地GND3的可调支路T。本申请对于可调支路T的位置不做具体的限定，该可调支路T可为第一子支路141、或第二子支路142、或第三子支路143、或新增在第一馈电点A与第一子支路141之间、或新增在第一子支路141与第二子支路142之间、或新增在第三子支路143与第四子支路144之间等。可调支路T用于调谐第一谐振模式a和第三谐振模式c的谐振频率。具体的，可调支路T用于调节第一谐振模式a的谐振频点的位置和第三谐振模式c的谐振频点的位置，以使扩展第一谐振模式a和第三谐振模式c支持所需的频段范围，例如，设有可调支路T的第一匹配模块M1将第一谐振模式a的谐振频率从1.77GHz移动至1.92GHz， 将第三谐振模式c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20，可调支路T为第二支路15的一部分。进一步具体的，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21，L111的电感值为4.3nH，L112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。图21中，S21为开关导通L111至第一匹配模块M1时第一天线单元10的S参数曲线图；S21L e为开关导通L112至第一匹配模块M1时第一天线单元10的S参数曲线图；S22为开关导通L111至第一匹配模块M1时第二天线单元20的S参数曲线图；S22`为开关导通L112至第一匹配模块M1时第二天线单元20的S参数曲线图；S23为开关导通L111至第一匹配模块M1时第一天线单元10与第二天线单元20之间的隔离度曲线图；S23`为开关导通L112至第一匹配模块M1时第一天线单元10与第二天线单元20的隔离度曲线图。
当开关导通L111至第一匹配模块M1中时，第一谐振模式a的谐振频率为1.77GHz，第二谐振模式b的谐振频率为3.6GHz；当开关导通L112至第一匹配模块M1中时，第一谐振模式a的谐振频率为1.92GHz，第二谐振模式b的谐振频率为3.7GHz。
在第一匹配模块M1设有可调支路T的情况下，本实施方式还通过对第一馈电点A的位置进行设计等方式，使可调支路T在对第一谐振模式a、第三谐振模式c进行调谐的同时，但是不会影响到或较少的影响到第二谐振模式b、第四谐振模式d和第五谐振模式e，从而在确保第一匹配模块M1在调谐第一谐振模式a、第三谐振模式c，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，还可以确保天线组件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、第四谐振模式d、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，第一馈电点A处的调谐对于第二谐振模式b、第四谐振模式d的谐振影响相对较小，对于第五谐振模式e的谐振影响相对较大。
对于第五谐振模式e而言，第一辐射体11的电流密度分布从第一耦合端112至第一接地端111为先增加后减小再增加(例如图19中的虚线处)，其中，第一辐射体11的电流强点位于从第一耦合端112至第一接地端111的长度的1/3左右。第一馈电点A与第一接地端111之间的长度为第一辐射体11长度的(1/3～1)倍。可选的，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。
通过设置第一馈电点A位于第一辐射体11的电流强点的位置或电流强点附近。第一馈电点A与第一接地端111之间的长度为第一辐射体11长度的(1/3～1)倍。进一步地，第一馈电点A与第一耦合端112之间的长度为第一辐射体11长度的1/3倍附近，以使第一馈电点A位于电流较强的位置。当第一馈电点A位于电流较强的位置时，第一匹配模块M1中设置可调支路T，该可调支路T对于第五谐振模式e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，还可以确保天线组件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4.5GHz～7GHz的频段传送第二馈电点B，或者，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4.5GHz～7GHz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与第二天线之间的隔离度。
以下结合附图对于第二匹配模块M2进行具体的说明。
请参阅图22，所述第二匹配模块M2包括至少一个并联至地的第三支路16和/或至少一个串联于所 述第二馈电点B与所述第二馈电模块23之间的第四支路17。所述第三支路16、所述第四支路17皆包括电容、电感中的至少一者。所述第二匹配模块M2用于导通所述第四谐振模式d和所述第五谐振模式e所支持的频段(例如WiFi 5G频段)，及阻隔小于所述第四谐振模式d和所述第五谐振模式e所支持频段的频段(例如第一天线单元10所支持的频段)，增加第一天线单元10和第二天线单元20之间的隔离度，及调谐所述第四谐振模式d的谐振频率和/或所述第五谐振模式e的谐振频率，以使第四谐振模式d和第五谐振模式e支持WiFi 5G、WiFi 6E频段。
第三支路16包括但不限于单电容支路、单电感支路以及图11至图18所列举的选频滤波电路中的至少一者。
第四支路17包括但不限于单电容支路、单电感支路以及图11至图18所列举的选频滤波电路中的至少一者。
举例而言，请参阅图22，至少一个所述第三支路16包括第六子支路161及第七子支路162。所述第六子支路161的一端电连接所述第二馈电点B，所述第六子支路161的另一端电连接所述第七子支路162的一端，所述第六子支路161包括并联的电感和电容，记为C21和L21。
所述第七子支路162的另一端电连接所述第二馈电模块23，所述第七子支路162包括电容、或电感、或并联的电感及电容。本实施方式中，第七子支路162为电感，记为L22。
请参阅图22，至少一个所述第四支路17包括第八子支路。所述第八子支路的一端电连接于所述第二馈电模块23，所述第八子支路的另一端电连接至第四参考地GND4，所述第八子支路包括电容、电感中的至少一者。本实施方式中，第八子支路为电感，记为L23。
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，还可以在第六子支路161与第二馈电点B之间增加支路。
其中，第六子支路161(L21、C21)和第七子支路162(L22)用于阻隔WiFi 2.4G频段、第二谐振模式b的频段、第三谐振模式c的频段，及导通WiFi 5G、WiFi 6E的频段。举例而言，L21＝13nH，C21＝0.3pF，L22＝2.7nH，上述的第六子支路161和第七子支路162对于WIFI 5G频段呈低阻抗或带通，以导通WIFI 5G频段，还能够有效地过滤掉小于WIFI 5G频段的频段，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。第八子支路L23对WiFi 5G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。举例而言，L23＝1.5nH。
从图4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S2，1，可以看出，1～3GHz、6～7GHz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。

以上为一个天线组件100用于待测主体接近检测和天线信号传输的具体结构、以及天线组件100中的各个器件在电子设备1000的安装位置。当然，本申请中，天线组件100的数量为一个或多个。
本申请对于天线组件100在电子设备1000内的具体所在侧不进行限定。参考地GND呈矩形板状。参考地GND包括依次连接的多个侧边。相邻的两个侧边之间的连接处为拐角处。
至少一个天线组件100的第一辐射体11、第二辐射体21与两个相交的侧边及拐角处相对设置；和/或，至少一个天线组件100的第一辐射体11、第二辐射体21全部与一个侧边相对设置。具体通过以下实施方式进行举例说明。
请参阅图23，参考地GND包括相对设置的第一侧边61和第二侧边62，以及连接于第一侧边61和第二侧边62之间的第三侧边63和第四侧边64。相邻的两个侧边之间的连接处为拐角处65。其中，第一侧边61为参考地GND的顶边(以用户竖屏手持并使用电子设备1000的状态为参考)，第二侧边62为参考地GND的底边。
请参阅图23，边框210包括多个首尾相连的侧边框。边框210的多个侧边框中，相邻的两个侧边框相交，例如相邻的两个侧边框通过圆弧倒角过渡连接。多个侧边框包括相对设置的顶边框2101和底边框2102，及连接于顶边框2101与底边框2102之间的第一侧边框2103和第二侧边框2104。其中，顶边框2101为操作者手持电子设备1000朝向电子设备1000的正面使用时远离地面的边，底边框2102为朝向地面的边。相邻的两个侧边框之间的连接处为拐角部2106。其中，顶边框2101和底边框2102平行且相等。第一侧边框2103和第二侧边框2104平行且相等。第一侧边框2103的长度大于顶边框2101的长度。其中，顶边框2101与第一侧边61相对设置，底边框2102与第二侧边62相对设置，第一侧边框2103与第三侧边63相对设置，第二侧边框2104与第四侧边64相对设置。
所述天线组件100设于所述顶边框210、所述第一侧边框2103、所述第二侧边框2104及所述底边框210中的至少一者。
在一实施方式中，请参阅图23，天线组件100的数量为一个。天线组件100的第一辐射体11、第二辐射体21与第一侧边框2103集成为一体。其中，第一耦合缝隙140靠近于或位于第一侧边框2103的中间位置。
请参阅图24，图24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边框210213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的位置与顶框框或底边框210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。
图25是天线组件100设于电子设备1000的侧边时的效率曲线。图25中S11曲线为第一天线单元10的系统辐射效率曲线。图25中S12曲线为第二天线单元10的系统辐射效率曲线。图25中S13曲线为第一天线单元10的系统总效率曲线。图25中S14曲线为第一天线单元10的系统总效率曲线。由于侧边净空小，天线组件100的辐射环境较为恶劣，但从图25中的标记1～6可以看出，在第一谐振模式a至第五谐振模式e所支持的频段内，皆具有相对较高的效率(例如，以图24中-6dB以上为具有相对较高效率的参考线)，以满足天线组件100在电子设备1000中的应用。
当然，在其他实施方式中，请参阅图26，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27，天线组件100的第一辐射体11、第二辐射体21还可以集成于顶边框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28及图30，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一天线单元10的结构和尺寸。
可选的，请参阅图30，在第一接地端111与第三接地端311之间增加导电体将第一辐射体11与第三辐射体31连接起来。进一步地，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，第一辐射体11与第三辐射体31之间可不做切断，即将边框210的一部分作为第一辐射体11，将边框210的另一部分作为第三辐射体31。换言之，第一辐射体11与第三辐射体31形成共体辐射体32。
可选的，请参阅图31，天线组件100还包括第四匹配模块M4。第四匹配模块M4的一端电连接于第一接地端111，第四匹配模块M4的另一端电连接至第一参考地GND1。其中，第四匹配模块M4对第一天线单元10、第二天线单元20中需要在第一接地端111回地的谐振模式(例如第一谐振模式a) 所支持频段呈低阻抗状态，例如，第四匹配模块M4为电感，以使需要在第一接地端111回地的谐振模式的谐振电流回地。
可选的，请参阅图31，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(例如第五谐振模式e)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中需要在第一接地端111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32，定义第一辐射体11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包括直接电连接第一接地端111的容性器件或在第四匹配模块M4与第一接地端111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；第一匹配模块M1包括直接电连接第一馈电点A的容性器件或在第一馈电点A与第一匹配模块M1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一接地端111；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一接地端111。
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，电容电连接于第一接地端111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一接地端111、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32，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。检测电路也可以放在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，第二辐射体21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。

具体的，第十一谐振模式k为第四馈电模块43的激励电流(第十一谐振电流)谐振于第四馈电点D至第二自由端411的(1/8～1/4)波长模式。具体的，通过设计第四馈电点D至第二自由端411的长度约为第四馈电模块43发送至第四辐射体41的激励电流在介质中的波长的(1/8～1/4)倍，以在第四馈电点D至第二自由端411上激励起第十一谐振模式k。
一般地，通过设计第四馈电点D至第二自由端411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f4处(第十一谐振模式k的谐振频率)易激励起较高的辐射效率。进一步地，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，而是可以在第四馈电点D至第二自由端411的长度对应1/8～1/4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f4形成谐振的同时还能够使所对应的第四馈电点D至第二自由端411的长度缩短，例如，减小至第十一谐振频点f4对应的波长的1/8倍等，进一步地减小第四馈电点D至第二自由端411的尺寸，减小天线组件100的堆叠长度。

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，以使第一辐射体11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。
具体的，请参阅图47，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电连接于第一接地端111与第一参考地GND1(具体为第一接地端111与第四匹配模块M4)之间。第二子隔离器72电连接于第一馈电点A与第一匹配模块M1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。具体的，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对第一匹配电路M1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。
具体的，过滤组件50电连接于第一子隔离器71与第一接地端111之间；或，电连接于第二子隔离器72与第一馈电点A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。
