请参照图1，图1为本申请实施例提供的一种电子设备1000的结构示意图。所述电子设备1000包括天线系统100。所述天线系统100用于收发电磁波信号，以实现所述电子设备1000的通信功能。本申请对于所述天线系统100在所述电子设备1000上的位置不做具体的限定，图1只是一种示例。所述电子设备1000还包括相互盖合连接的显示屏200及壳体300。所述天线系统100可设于所述电子设备1000的壳体300内部、或部分与所述壳体300集成为一体、或部分设于所述壳体300外。图1中所述天线系统100的辐射体与所述壳体300集成为一体。当然，所述天线系统100还可以设于所述电子设备1000的可伸缩组件上，换言之，所述天线系统100的至少部分还能够随着所述电子设备1000的可伸缩组件伸出所述电子设备1000之外，及随着可伸缩组件缩回至所述电子设备1000内；或者，所述天线系统100的整体长度随着所述电子设备1000的可伸缩组件的伸长而伸长。
所述电子设备1000包括不限于为手机、电话、电视、平板电脑、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。本申请中以所述电子设备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，以所述电子设备1000处于图1中的视角为参照，所述电子设备1000的宽度方向定义为X轴方向，所述电子设备1000的长度方向定义为Y轴方向，所述电子设备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，所述壳体300包括边框310及后盖320。所述边框310内通过注塑形成中板330，所述中板330上形成多个用于安装各种电子器件的安装槽。所述中板330与所述边框310一起成为所述电子设备1000的中板330。所述显示屏200、所述中框340及所述后盖320盖合后在所述中框340的两侧皆形成收容空间。所述边框310的一侧(例如后侧)围接于所述后盖320的周沿，所述边框310的另一侧(例如前侧)围接于所述显示屏200的周沿。所述电子设备1000还包括设于收容空间内的电路板500、电池600、摄像头模组、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。可以理解地，上述对电子设备1000的介绍仅是所述天线系统100所应用的一种环境的说明，所述电子设备1000的具体结构不应当理解为对本申请提供的天线系统100的限定。
以下结合附图对于本申请提供的所述天线系统100的具体结构进行举例说明，当然，本申请提供的所述天线系统100包括但不限于以下的实施方式。
请参阅图3及图4，天线系统100包括至少三个第一辐射体10及至少一个第二辐射体20。
其中，所述至少三个第一辐射体10中至少一者能够发射预设低频信号。可以理解的，第一辐射体10为低频辐射体。所述预设低频信号用于与基站或其他终端建立通信连接。该预设低频信号包括但不限于为B5等。
其中，所有的所述第一辐射体10皆至少能够接收预设低频信号。具体的，每个第一辐射体10能够接 收预设低频信号，可选的，每个第一辐射体10在接收除了预设低频信号之外，还能够接收其他的低频信号。每个第一辐射体10所接收的低频信号的频段为低频信号段(例如小于1000MHz)中任意一个频段，包括但不限于为B5、N20、N5、N8、N28等。可以理解的，本申请所述的低频频段包括但不限于为5G移动通信信号或4G移动通信信号。对于第一辐射体10而言，可以是独立支持5G移动通信信号或4G移动通信信号，也可以是同时支持5G移动通信信号和4G移动通信信号的辐射体。
目前，低频信号在各个场所皆具有非常广泛的应用。例如，频段越低，覆盖范围越广。低频信号在覆盖农村、戈壁、山川、河流、森林等区域具有极大的潜力，也是城市5G覆盖的有力补充。农村、戈壁、山川、河流、森林等人烟相对稀少的区域，建立相对较多的基站数量的成本较高，提高电子设备1000对于低频信号的接收强度，以接收相对更远的基站的信号，成为研发的方向之一。
而由于第一辐射体10的长度相对较长，电子设备1000，特别是便携式电子设备1000中，既要确保其轻便性还要同时满足支持其他的频段，例如，支持MHB频段(中高频段)的移动通信信号、UHB频段(超高频段)的移动通信信号、Wi-Fi信号、GNSS信号等的功能，这些频段的支持也需要设置相应的辐射体，如此，导致电子设备1000中留给第一辐射体10的位置极其有限。有限的空间位置限制了第一辐射体10的数量，也限制了低频信号的接收能力，导致低频信号的覆盖深度和吞吐率皆有限，也限制了低频信号在农村、戈壁、山川、河流、森林等区域的应用。此外，由于便携式电子设备1000时常被用户握持，用户握持会降低辐射体的工作效率。在第一辐射体10原本数量就极其有限的情况下，还可能存在被用户握死的风险，如此，将导致便携式电子设备1000内的第一辐射体10的应用效率低。
本实施方式中，第一辐射体10的数量可以为三个、四个等。且设置至少一个所述第二辐射体20与至少一个所述第一辐射体10之间通过耦合缝隙13耦合。其中，所述第二辐射体20所支持的频段的最小值大于或等于所述预设低频信号的频段的最大值。所述第二辐射体20所支持的信号包括但不限于为MHB频段的移动通信信号、UHB频段的移动通信信号、Wi-Fi信号、GNSS信号中的至少一者。其中，所述第二辐射体20可支持MHB+UHB频段的移动通信信号。其中，GNSS全称为Global Navigation Satellite System，中文名称为全球导航卫星系统，GNSS包括全球性的全球定位系统(Global Positioning System，GPS)、北斗、全球卫星导航系统(Global Navigation Satellite System,GLONASS)、伽利略卫星导航系统(Galileo satellite navigation system，Galileo)以及区域性导航系统等。
换言之，第二辐射体20可以为中频辐射体、高频辐射体、中高频辐射体、Wi-Fi辐射体或GNSS辐射体。其中，MHB频段为大于或等于1000MHz且小于3000MHz；UHB频段为大于或等于3000MHz且小于10000MHz。Wi-Fi信号包括但不限于Wi-Fi 2.4G频段(2.4～2.5GHz)、Wi-Fi 5G频段(5.15～5.85GHz)、Wi-Fi 6E频段。GNSS信号包括但不限于GPS-L1频段(1575GHz)、GPS-L5频段(1176GHz)。MHB+UHB频段为大于或等于1000MHz且小于10000MHz。
可选的，第二辐射体20的数量可以为一个、两个、三个、四个等。其中，一个第二辐射体20可以与一个第一辐射体10相耦合。当然，一个第二辐射体20还可以与两个第一辐射体10耦合。进一步地，两个第二辐射体20还可以与一个第一辐射体10相耦合。多个第二辐射体20中可以是部分的第二辐射体20与第一辐射体10相耦合，也可以是全部的第二辐射体20与第一辐射体10耦合。
请参阅图3，当所述第二辐射体20与所述第一辐射体10耦合设置时，所述第二辐射体20与所述第一辐射体10之间具有耦合缝隙13。例如，所述耦合缝隙13的宽度可以为0.5～2mm，但不限于此尺寸。所述第二辐射体20与所述第一辐射体10通过所述耦合缝隙13容性耦合。其中，“容性耦合”是指，所述第二辐射体20与所述第一辐射体10之间产生电场，所述第二辐射体20上的电信号能够通过电场传递至所述第一辐射体10，及所述第一辐射体10上的电信号能够通过电场传递至所述第二辐射体20，以使所述第一辐射体10与所述第二辐射体20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，也可称为第二辐射体20与第一辐射体10共口径。
如此，第一辐射体10也能够用于支持MHB频段的移动通信信号、UHB频段的移动通信信号、Wi-Fi信号、GNSS信号中的至少一者，或者说，第二辐射体20也能够支持低频频段。也就是说，第一辐射体10和第二辐射体20能够相互复用，如此，在有限的辐射体长度下，实现了所支持的频段多、频带宽，且所需的辐射体长度相对较短，节省了电子设备1000上的空间，以腾出空间设置多个第一辐射体10。
本实施方式中，所有的第一辐射体10皆能够接收低频信号。第一辐射体10的数量越多，对于低频信号的接收增强，更利于提升低频的覆盖广度和深度。再例如，多个第一辐射体10方向图皆朝向同一方向时，多个第一辐射体10的信号增益叠加，进而能够应用于农村、戈壁、山川、河流、森林等区域以连接到更远距离的天线基站，如此，可在人烟较少的区域设置相对较远距离的基站，提升低频覆盖广度；或者， 在电梯、地下车库、仓库等信号相对较弱的区域也能够具有较好的信号强度，提升覆盖深度，确保通讯质量。
此外，不同的第一辐射体10还可以朝向不同的方向，即至少两个第一辐射体10的方向图朝向不同，则至少两个第一辐射体10的方向图互补，以提高天线系统100对于低频信号的接收角度范围，提升低频覆盖广度。例如，当用户手握持具有该天线系统100的电子设备1000时，用户握死部分第一辐射体10，多支第一辐射体10之间可以相互切换，以切换至工作效率较高的第一辐射体10工作，以确保电子设备1000在握持状态也具有较高的工作效率。
请参阅图5，所述天线系统100还包括第一馈电系统30。所述第一馈电系统30电连接所述第二辐射体20。第一馈电系统30包括第一馈源31及第三匹配电路32(其中，第一匹配电路和第二匹配电路在后续进行说明)。第一馈源31电连接射频信号源。射频信号源包括但不限于射频收发模组、射频接收模组、射频发射模组等中的至少一者。本申请中，射频信号源用于接收或发射MHB频段的移动通信信号、UHB频段的移动通信信号、Wi-Fi信号、GNSS信号中的至少一者。

换言之，所述第一馈电系统30不仅可以利用其直接电连接的第二辐射体20收发MHB频段，还能够复用原本用于支持低频信号的第一辐射体10收发MHB频段，如此，第二辐射体20的长度小于收发MHB频段的辐射体长度，可实现在支持多频段、超宽带的同时还能够减小辐射体的整体长度，如此，节省电子设备1000上的空间，利于电子设备1000上设置更多数量的第一辐射体10。
请参阅图5，所述天线系统100还包括第二馈电系统40。所述第二馈电系统40电连接所述第一辐射体10。第二馈电系统40包括第二馈源41及第四匹配电路42。第二馈源41电连接射频信号源。射频信号源包括但不限于射频收发模组、射频接收模组、射频发射模组等中的至少一者。本申请中，射频信号源用于接收或发射低频信号，具体频段为0～1000MHB，信号类型包括但不限于为4G移动通信信号、5G移动通信信号。

所述第二馈电系统40电连接所述第一辐射体10上的第二馈电点B。可选的，第二馈电系统40可设于电子设备1000内的电路板上，通过导电弹片与第一辐射体10的第二馈电点B电连接。当然，在其他实施方式中，第二馈电系统40还可以通过导电卡合件、导电胶、导电焊接盘等方式与第一辐射体10的第二馈电点B电连接。

本申请对于作用端11的设计包括但不限于以下的实施方式。
在第一种作用端11的实施方式中，请参阅图5，所述作用端11接地，即电连接参考地系统GND。作用端11也可以成为“接地端”。此时，第一辐射体10形成倒F天线。
第一辐射体10复用作为第一馈电系统30收发MHB频段的辐射体。举例而言，所述第一馈电系统30至少激励所述第二耦合端12与所述第二馈电点B之间的部分产生谐振。可选的，第一馈电系统30激励所述第二耦合端12与所述第二馈电点B之间的部分产生MHB频段对应的1/4波长模式的谐振模式。图5所示1/4波长模式的谐振电流(图5中虚线箭头所示)主要分布在所述第二耦合端12与所述第二馈电点B之间。当然，也可以有少部分的谐振电流分布在第二馈电点B与作用端11之间、或者分布在第二辐射体20上。可以理解的，上述的1/4波长模式只是第一馈电系统30收发MHB频段的其中一个谐振模式。
图5所示1/4波长模式的谐振电流的方向为从所述第二馈电点B流向所述第二耦合端12(即耦合缝隙13)。当然，谐振电流的方向还可以从所述第二耦合端12(即耦合缝隙13)流向所述第二馈电点B。
其中，从一种便于理解角度说明，1/4波长模式可理解为所述第二耦合端12与所述第二馈电点B之间的有效电长度约为谐振模式的中心频率对应的介质波长(在介质中的波长)的1/4倍，此描述为对于术语便于理解的解释，但不能作为所述第二耦合端12与所述第二馈电点B之间的长度的限定。
通过对所述第二耦合端12与所述第二馈电点B之间的有效电长度进行设计，即对第二馈电点B的位置进行设计，以使所述第二耦合端12与所述第二馈电点B之间的有效电长度对应于所需支持所述MHB频段的1/4介质波长。其中，所述的“对应”可理解为所述第二耦合端12与所述第二馈电点B之间的有效电长度约为所需支持所述MHB频段的1/4介质波长。其中，1/4波长模式也可以称为基态，基态下具有较高的天线效率，进而提高对于所需支持所述MHB频段的收发效率。
需要说明的是，本申请所述第二耦合端12与所述第二馈电点B之间的有效电长度约为某一频段的某一介质波长，并不限定第二耦合端12与所述第二馈电点B之间的物理长度为该频段的该介质波长。因为可以在第二耦合端12与所述第二馈电点B之间电连接一些调谐器件，以调谐第二耦合端12与所述第二馈电点B之间的有效电长度，例如，通过设置电感、电容，以增加或减小第二耦合端12与所述第二馈电点B之间的有效电长度。

在第二种作用端11的实施方式中，请参阅图6，所述作用端11为自由端。即作用端11不电连接于参考地系统GND，也不会与其他的辐射体形成耦合。在电子设备1000的边框310上，作用端11可通过绝缘断缝与其他的辐射体进行隔开。此时，第一辐射体10形成T型天线。
当然，第一辐射体10的形式不限于上述的倒F天线、T型天线，还可以是回路天线(LOOP天线)等。
请参阅图6，所述第一辐射体10还可以具有位于所述第二馈电点B与所述第二耦合端12之间的第一匹配点D。
请参阅图6，所述天线系统100还包括第一匹配电路M1。所述第一匹配电路M1的一端电连接所述第一匹配点D，所述第一匹配电路M1的另一端接地。所述第一馈电系统30至少激励所述第二耦合端12与所述第一匹配点D之间的部分产生谐振。可选的，第一馈电系统30激励所述第二耦合端12与所述第一匹配点D之间的部分产生MHB频段对应的1/4波长模式的谐振模式。图6所示1/4波长模式的谐振电流(图6中虚线箭头所示)主要分布在所述第二耦合端12与所述第一匹配点D之间。当然，也可以有少部分的谐振电流分布在第一匹配点D与作用端11之间、或者分布在第二辐射体20上。可以理解的，上述的1/4波长模式只是第一馈电系统30收发MHB频段的其中一个谐振模式。
所述第一匹配电路M1包括电容器件、电感器件、开关调谐器件中的至少一者。可以理解的，第一匹配电路M1对MHB频段对应的1/4波长模式的谐振电流呈低阻抗状态，即可将MHB频段对应的1/4波长 模式的谐振电流回地，增加了MHB频段的谐振电流的路径，以支持MHB频段对应的1/4波长模式。
图6所示1/4波长模式的谐振电流的方向为从所述第一匹配点D流向所述第二耦合端12(即耦合缝隙13)。当然，谐振电流的方向还可以从所述第二耦合端12(即耦合缝隙13)流向所述第一匹配点D。
通过对所述第二耦合端12与所述第一匹配点D之间的有效电长度、第一匹配电路M1进行设计，以使支持所述MHB频段的1/4介质波长的谐振电流经第一匹配电路M1回地，以支持MHB频段对应的1/4波长模式。
以上为第一辐射体10复用作为第一馈电系统30收发MHB频段的辐射体的一种具体举例，在其他实施方式中，通过对第一匹配点D的位置设计，还可以使第一馈电系统30激励所述第二耦合端12与所述第一匹配点D之间的部分产生MHB频段对应的1/2、3/4或1倍波长模式的谐振模式。

由于低频频段需要相对较长的辐射体支持，而第二辐射体20的物理长度相对较短，故通过设置所述第二匹配电路M2包括电容器件。电容器件接地。电容器件将所述第一耦合端22与所述第二匹配点E之间的部分产生谐振的谐振频率向低偏移。例如，原本所述第一耦合端22与所述第二匹配点E之间的部分产生谐振的谐振频率为1500MHz，通过在第二匹配点E设置电容器件，电容器件将谐振频率从1500MHz调节至1000MHz附近，以实现第二辐射体20对于低频频段的支持。电容器件对上述低频频段对应的1/4波长模式的谐振电流呈低阻抗状态，即可将上述低频频段对应的1/4波长模式的谐振电流回地，增加了低频频段的谐振电流的路径，以支持低频频段对应的1/4波长模式。
图7所示1/4波长模式的谐振电流的方向为从所述第一耦合端22(即耦合缝隙13)流向所述第二匹配点E。当然，谐振电流的方向还可以从所述第二匹配点E流向所述第一耦合端22(即耦合缝隙13)。

在一般技术中，天线系统100的辐射系统会受到手握持的影响，例如，不同手握姿势时，会握住不同天线(即辐射体)，导致该天线的辐射效率低，工作环境差。例如，图8中，竖握时天线ANT0有很大概率被握死，横握时天线ANT1有很大概率被握死。而用户的握持手势是不确定的，也就是说，电子设备1000中的天线可能会发生被握死的现象，而发射天线(发射天线为用于发射的辐射体)被握死的话将导致电子设备1000无法与基站进行连接或连接不良，即电子设备1000无信号或信号极弱，导致用户的体验。

上述的过程可以是实时动态的过程。即第一检测模组70实时检测多个第一辐射体10的信号接收强度，控制器实时调节第一开关模块61，实现智能切换，以确保无论多个第一辐射体10的工作环境如何变化(或者手握姿势如何变化)，都能够将信号接收强度最优的第一辐射体10作为发射辐射体，其他的第一辐射体10作为接收辐射体，以在不同的手握姿势时保持发射辐射体具有较好的信号质量，提高电子设备1000的信号稳定性，提高用户的使用体验。

请参阅图11，三个所述第一辐射体10分别记为第一子辐射体101、第二子辐射体102、第三子辐射体103。以电子设备1000的后盖320侧的视角为例，边框310包括依次设置的第一侧边311、第二侧边312、第三侧边313、第四侧边314。其中，第一侧边311为顶边，第二侧边312为朝向图11所示的边框310的视角的左手边，第三侧边313为底边，第四侧边314为朝向图11所示的边框310的视角的右手边。
三个所述第一辐射体10尽可能的排布在边框310的多侧，以在不同的方向辐射天线信号，还可以应对不同的握持手势。本实施方式以第一子辐射体101设于边框310的第二侧边312(例如，中间部分)、第二子辐射体102设于边框310的第三侧边313(即底边)、第三子辐射体103设于边框310的第四侧边314的中间位置为例进行举例说明，不限于此布局方式。如此布局，当用户横屏握持(用户朝向显示屏)时，第一子辐射体101和第三子辐射体103未被遮挡，可具有较高的信号强度；当用户竖屏握持(用户朝向显示屏)时，第二子辐射体102未被遮挡，可具有较高的信号强度。
请参阅图12，所述至少三个第一射频模组50包括两个所述第一射频收发模组52及一个所述第一射频接收模组51。两个第一射频收发模组52分别记为第一收发模组521和第二收发模组522。所述第一控制模组60电连接三个所述第一辐射体10、所述第一收发模组521、所述第二收发模组522及所述第一射频接收模组51。第一控制模组60控制三个第一辐射体10分别电连接所述第一收发模组521、所述第二收发模组522及所述第一射频接收模组51。
在图11中，3P3T表示三刀三掷可以任意切换的第一开关模块61，不限于此方式，后面进行具体详述。TX1/RX表示电连接一个第一射频收发模组52的接口，TX2/RX表示电连接另一个第一射频收发模组52的接口。RX表示电连接第一射频接收模组51的接口。PA-1表示电连接一个第一射频收发模组52的第一个功率源。PA-2表示电连接另一个第一射频收发模组52的第二个功率源。
所述第一检测模组70用于根据三个所述第一辐射体10的信号强度确定三个所述第一辐射体10中的两者为两个所述目标第一辐射体10a，另一者为所述非目标第一辐射体10b。
请参阅图12，所述第一控制模组60用于在所述第一检测模组70确定两个所述目标第一辐射体10a之后切换所述第一收发模组521电连接至两个所述目标第一辐射体10a中的一者、切换所述第二收发模组522电连接至两个所述目标第一辐射体10a中的另一者、及在所述第一检测模组70确定所述非目标第一辐射体10b之后切换所述第一射频接收模组51电连接至所述非目标第一辐射体10b。
换言之，所述第一控制模组60根据三个第一辐射体10的信号强度，实时切换三个第一辐射体10中信号强度较强的两个第一辐射体10进行接收和发射工作，另一个信号强度相对较弱的第一辐射体10进行接收工作。从功能上进行划分，工作时形成了两个发射天线和三个接收天线，利于支持LB频段+LB频段，即利于支持两个不同的低频频段。
本实施例中，将两个第一辐射体10作为可发射可接收的辐射体。将可发射的辐射体称为发射天线，发射天线的数量越多，天线增益叠加，覆盖范围(通信距离)扩大很多倍。当多个发射天线方向图叠加时，多个发射天线的信号增益叠加，进而能够应用于农村、戈壁、山川、河流、森林等区域以连接到更远距离的天线基站，如此，可在人烟较少的区域设置相对较远距离的基站，提升低频覆盖广度；或者，在电梯、地下车库、仓库等信号相对较弱的区域也能够具有较好的信号强度，提升覆盖深度，确保通讯质量。当多个发射天线的方向图互补时，多个发射天线可提高信号覆盖角度，利于接收到不同方向的基站信号。
此外，发射天线越多的话，两支发射天线可以分别支持4G移动通信信号和5G移动通信信号，利于实现4G-5G双连接(即4G-5G ENDC)；或者，电子设备1000具有双卡配置时，一个SM卡需要一支发射天线支持5G移动通信信号，另一个SM卡需要另一支发射天线支持4G-5G ENDC移动通信信号等。
综上，多个发射天线利于增加天线增益、扩大覆盖范围、提升信号质量，以支持双卡配置等。
本实施方式中以两个第一辐射体10用于发射，在其他实施方式中，还可以以三个或三个以上的第一辐射体10用于发射，一支发射天线可支持4G-5G ENDC，其他支发射天线支持4G移动通信信号、或5G移动通信信号、或4G-5G ENDC移动通信信号等。
多个接收天线(接收天线为用于接收的辐射体)能够增加空间分集，提升电子设备1000的下载数据，提高电子设备1000的上网速度，提升用户体验。

以上第一检测模组70、第一控制模组60相配合以实现在不同的握持手势下的发射天线和接收天线的切换，以实现发射天线具有较好的信号强度，且由于发射天线同时能够实现接收，故天线系统100仍具有较好的信号收发能力。
本实施方式还能够以相对较少数量的第一辐射体10同时支持两个不同的低频频段，以下进行具体的说明。
可选的，所述第一收发模组521用于发射第一低频信号，所述第二收发模组522用于发射第二低频信号。第一低频信号和第二低频信号的频段不同，例如，第一低频信号为B20、N28中的一者，第二低频信号为B20、N28中的另一者。
所述第一控制模组60还用于在三个所述第一辐射体10中选择两者接收所述第一低频信号及选择另两者接收所述第二低频信号。例如，第一子辐射体101和第二子辐射体102支持B20的接收，第一子辐射体101和第三子辐射体103支持N28的接收，如此，实现了以三支第一辐射体10同时支持两个不同的低频频段，既实现了对于两个不同的低频频段的同时支持，还减少了第一辐射体10的数量，节省了所占据的空间，为电子设备1000设置其他的辐射体创造了空间条件。

请参阅图15及图16，当用户竖屏握持(例如右手握持)时，第一检测模组70检测到第三子辐射体103的信号强度相对较高，确定第三子辐射体103为目标第一辐射体10a，其他的第一辐射体10为非目标第一辐射体10b。控制器控制第一开关模块61切换第一射频收发模组52电连接至第三子辐射体103，及控制第一开关模块61切换第一接收模组511、第二接收模组512和第三接收模组513分别电连接第二子辐射体102、第一子辐射体101、第四子辐射体104。
以上第一检测模组70、第一控制模组60相配合以实现在不同的握持手势下的发射天线和接收天线的切换，以实现发射天线具有较好的信号强度，且由于发射天线同时能够实现接收，故天线系统100仍具有较好的信号收发能力。第一控制模组60能够切换第一射频收发模组52电连接至四个第一辐射体10中的任意一个，那么每个第一辐射体10皆能够支持信号发射和接收，如此，实现了低频段的4*4多进多出(Multiple input Multiple output，MIMO)，低频信号可以为5G或4G信号，即利于实现包括5G独立组网(SA)或非独立组网(NSA)低频段的4*4MIMO，利于提升天线信号的深度覆盖、增加吞吐量和提升下载速度，还实现5G独立组网(SA)低频段探照参考信号(Sounding Reference Signal，SRS)的1发射4接收。
本申请还提供了第二种第一控制模组60的实施方式，请参阅图18，第一控制模组60包括三刀三掷且可任意切换的第一开关模块61，三个所述第一辐射体10电连接所述第一开关模块61，另一个所述第一辐射体10电连接所述第一射频接收模组51或所述第一射频收发模组52。即第一开关模块61的三个输入端的第一射频模组50可以电连接至三个第一辐射体10中的任意一个。与第一辐射体10固定电连接的第一射频模组50可以是第一射频收发模组52、或第一接收模组511、或第二接收模组512、或第三接收模组513。

本实施方式中，未电连接第一控制模组60的第一辐射体10位于边框310的第二侧边312靠近第三侧边313的位置。边框310的第二侧边312靠近第三侧边313的位置容易在握持时发生遮挡，所以在边框310的第二侧边312靠近第三侧边313的位置不设置发射天线，在其他相对不易被握持遮挡的位置切换发射天线，可相对提高发射天线的辐射效率。相较于四个输入输出的开关模块，减少了控制端数量，节省成本。
当然，在其他实施方式中，固定天线还可以为设于在第二侧边312其他位置的第一辐射体10，设置在第一侧边311的第一辐射体10，设置在第三侧边313的第一辐射体10，以及设置在第四侧边314的第一辐射体10。

本实施例与第二种工作模式的天线系统100的实施例不同主要在于：
请参阅图20及图21，所述至少三个第一射频模组50包括两个所述第一射频收发模组52及两个所述第一射频接收模组51。
所述第一检测模组70用于根据至少一个所述第一控制模组60所电连接的所述第一辐射体10的信号强度在四个所述第一辐射体10中确定两个所述目标第一辐射体10a和两个所述非目标第一辐射体10b。

对于本实施例提供的四个第一辐射体10、两个第一射频收发模组52及两个所述第一射频接收模组51而言，本申请对于第一控制模组60包括以下的设计：
本实施例提供的第一种第一控制模组60的实施方式中，请参阅图20及图21，第一控制模组60包括四刀四掷且可任意切换的第一开关模块61，四个所述第一辐射体10皆电连接所述第一开关模块61的输出端。所述第一射频收发模组52可电连接至任意一个第一辐射体10。
所述第一控制模组60电连接四个所述第一辐射体10、所述第一接收模组511、所述第二接收模组512、所述第一收发模组521和所述第二收发模组522。
所述第一检测模组70用于根据四个所述第一辐射体10的信号强度确定四个所述第一辐射体10中的两者分别为两个所述目标第一辐射体10a，另两者分别为两个所述非目标第一辐射体10b。
所述第一控制模组60用于在所述第一检测模组70确定两个所述目标第一辐射体10a之后切换所述第一收发模组521和所述第二收发模组522分别电连接至两个所述目标第一辐射体10a，及在所述第一检测模组70确定两个所述非目标第一辐射体10b之后切换所述第一接收模组511和所述第二接收模组512分别电连接至两个所述非目标第一辐射体10b。在功能上，实现两个第一辐射体10发射和四个第一辐射体10接收。
换言之，所述第一控制模组60根据四个第一辐射体10的信号强度，实时切换四个第一辐射体10中信号强度较强的两个第一辐射体10进行接收和发射工作，另两个信号强度相对较弱的第一辐射体10进行接收工作。
多个接收天线能够提升电子设备1000的下载数据，提高电子设备1000的上网速度，提升用户体验。
本实施例提供的第二种第一控制模组60的实施方式，请参阅图22，所述第一控制模组60的数量为两个，每个所述第一控制模组60包括双刀双掷且任意切换的开关模块，四个所述第一辐射体10中的两者电连接一个所述第一控制模组60，四个所述第一辐射体10中的另两者电连接另一个所述第一控制模组60。两个第一控制模组60分别为相互独立的第一开关模块61和第二开关模块62。第一开关模块61为双刀双掷可任意切换的开关。第二开关模块62为双刀双掷可任意切换的开关。即双开关模块实现4天线切换。
第一开关模块61的两个输入端可以在第一收发模组521、第一接收模组511、第二收发模组522和第二接收模组512中任意的两者。第一开关模块61的两个输出端可以在第一子辐射体101、第二子辐射体102、第三子辐射体103和第四子辐射体104中任意的两者。
举例而言，请参阅图22，第一开关模块61的两个输入端分别电连接第一收发模组521(图22中TX1/RX为电连接第一收发模组521的接口)和第一接收模组511(图22中RX1为电连接第一接收模组511的接口)；第一开关模块61的两个输出端分别电连接第一子辐射体101和第四子辐射体104。第二开关模块62的两个输入端分别电连接第二收发模组522(图22中TX2/RX为电连接第二收发模组522的接口)和第二接收模组512(图22中RX2为电连接第二接收模组512的接口)；第二开关模块62的两个输出端分别电连接第二子辐射体102和第三子辐射体103。可选的，第一开关模块61和第二开关模块62皆为双刀双掷开关。
由于第一子辐射体101、第四子辐射体104设于边框310的整体左侧(以图22为参考)，第二子辐射体102、第三子辐射体103靠近于边框310的整体右侧，通过设置第一子辐射体101、第四子辐射体104中的一者为发射天线，第二子辐射体102、第三子辐射体103中的一者为发射天线，如此，两个发射天线的方向图互补，以提高天线系统100的信号覆盖广度。
此外，在研发过程中发现，第一子辐射体101容易激励起参考地系统GND的横向电流(沿第一侧边311的方向)，第四子辐射体104容易激励起参考地系统GND的纵向电流(沿第四侧边314的方向)，第一子辐射体101在参考地系统GND上激励起的电流模式与第四子辐射体104在参考地系统GND上激励起的电流模式不同，则第一子辐射体101和第四子辐射体104的方向图不同，如此实现第一子辐射体101的方向图和第四子辐射体104的方向图至少部分互补，如此，提高天线系统100的覆盖广度。相应地，第三子辐射体103容易激励起参考地系统GND的横向电流，第二子辐射体102容易激励起参考地系统GND的纵向电流，第三子辐射体103在参考地系统GND上激励起的电流模式与第二子辐射体102在参考地系统GND上激励起的电流模式不同，则第二子辐射体102和第三子辐射体103的方向图不同，如此实现第二子辐射体102的方向图和第三子辐射体103的方向图至少部分互补，如此，提高天线系统100的覆盖广度。
再举例而言，在其他的实施方式中，请参阅图23，第一开关模块61的两个输入端分别电连接第一收发模组521(图23中TX1/RX为电连接第一收发模组521的接口)和第一接收模组511(图23中RX1为电连接第一接收模组511的接口)；第一开关模块61的两个输出端分别电连接第一子辐射体101和第二子辐射体102。第二开关模块62的两个输入端分别电连接第二收发模组522(图23中TX2/RX为电连接第二收发模组522的接口)和第二接收模组512(图23中TX2/RX为电连接第二接收模组512的接口)；第 二开关模块62的两个输出端分别电连接第三子辐射体103和第四子辐射体104。
由于第一子辐射体101容易在参考地系统GND上激励起横向电流，第二子辐射体102容易在参考地系统GND上激励起纵向电流，而且第一子辐射体101与的第二子辐射体102呈对角设置。第一子辐射体101的方向图与的第二子辐射体102的方向图互补，以提高天线系统100的覆盖广度；相应地，第三子辐射体103容易在参考地系统GND上激励起横向电流，第四子辐射体104容易在参考地系统GND上激励起纵向电流，而且第三子辐射体103与的第四子辐射体104呈对角设置。第三子辐射体103的方向图与的第四子辐射体104的方向图互补，以提高天线系统100的覆盖广度。
