具体实施方式
为了便于理解本申请，下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的实施例。但是，本申请可以以许多不同的形式来实现，并不限于本文所描述的实施例。
第五代移动通信(5th Generation Mobile Networks，5G)引入的新空口NR技术，为无线通信提供了更多的可用频段及更大的带宽，从而可以提供极高的数据吞吐量。然而，由于5G基站建设成本高，导致目前5G服务的覆盖广度和深度不足，尤其是在中小城市及偏远山区，存在大量的5G服务盲点，导致5G信号的连续性差，从而影响用户体验。
为了解决上述问题，一种方式是采用4G LTE与5G NR建立双连接(Dual-Connectivity，DC)，又称演进的通用移动通信系统陆地无线接入网与新空口双连接(E-UTRA New Radio-Dual Connectivity，EN-DC)。EN-DC可以基于现有的4G核心网实现5G基站的快速部署，进而通过4G和5G的联合组网来实现全面的网络覆盖，提高整个网络系统的无线资源利用率、降低系统切换时延以及提高用户和系统性能。基于黄金频段800M及700M的双低频EN-DC是运营商实现5G快速部署,并增强上行覆盖的一种极佳的组网方式。双低频EN-DC要求用户设备(User Equipment，UE)具有至少两支低频天线，分别作为4G低频频段和5G低频频段的发射和主集接收天线，如果追求双低频EN-DC性能的更优化，比如采用独立的天线实现分集接收，则需要至少设置三支低频天线。另一种方式是充分利用5G低频频段(比如N28频段)，并结合多天线设计，在UE侧实现5G低频频段的多路接收，提升频谱利用率和网络容量。
上述两种解决方式均要求在UE内部同时设置多支低频天线，以最大化地提升双低频EN-DC和5G低频频段的通信性能。然而，对于智能手机、平板电脑等电子设备而言，随着5G频段的引入，在兼容原有4G频段的同时，还需要支持Wi-Fi、蓝牙、近场通信(Near Filed Communication，NFC)等短距离通信频段及全球卫星导航系统(Global Navigation Satellite System，GNSS)相关频段，如何在有限的电子设备内部空间中设计出能够满足各频段通信性能需求的多天线系统，是极具挑战的。

其中，第一天线辐射体120、第二天线辐射体130、第三天线辐射体140和第四天线辐射体150被配置为支持第一低频信号的四路接收，且第一天线辐射体120、第二天线辐射体130、第三天线辐射体140和第四天线辐射体150中的至少三者被配置为支持第一低频信号和第二低频信号的EN-DC双连接。在一种实施方式中，第一低频信号可以为5G NR的N28频段的信号，第二低频信号可以为4G LTE的B20频段的信号，从而实现N28频段信号的四路接收，同时实现N28和B20双低频频段的EN-DC双连接。当然，第一低频信号和第二低频信号并不限于N28和B20的组合，也可以是N8和B20，或者N5和B28等低频频段的组合。
参考图2，在一种实施方式中，第一天线辐射体120、第二天线辐射体130、第三天线辐射体140和第四天线辐射体150中的至少一者还被配置为支持第一低频信号的发射。例如，将第一天线辐射体120、第二天线辐射体130、第三天线辐射体140和第四天线辐射体150中辐射效率最高的辐射体配置为支持第一低频信号的发射的辐射体。可以理解，电子设备100可以通过测量各天线辐射体的发射功率及回退功率，并相互比较，从而确定效率最高的辐射体。通过上述方式，可以从第一天线辐射体120、第二天线辐射体130、第三天线辐射体140和第四天线辐射体150中选择出性能最优的辐射体来发射第一低频信号，从而实现第一低频信号的发射在四支低频天线之间的智能切换，确保了电子设备100的低频发射性能。
以第一低频信号为N28频段信号为例，第一天线辐射体120、第二天线辐射体130、第三天线辐射体140和第四天线辐射体150中的每一者均可被配置为支持N28频段信号的接收；第一天线辐射体120、第二天线辐射体130、第三天线辐射体140和第四天线辐射体150中辐射效率更高的一者或者二者还可被配置为支持N28频段信号的发射。如此，即可在电子设备100上实现N28频段信号的四路接收和至少一路发射。通过将第一天线辐射体120、第二天线辐射体130、第三天线辐射体140和第四天线辐射体150均配置为支持N28频段信号的接收，相对于传统两天线接收的方案，具有更远的覆盖范围，更好的弱场(室内，近海，山林等)覆盖，更高的下行速率，极大地提升了5G NR低频频段的频谱利用率和网络系统容量。
可以理解的是，基于第一天线辐射体120、第二天线辐射体130、第三天线辐射体140和第四天线辐射体150的布局，基于背面视角的设定，对于右手习惯的用户来说，通常第四天线辐射体150会被握持，此时该天线辐射体的辐射性能必然受到影响，为避免不必要的切换逻辑，第一低频信号的发射天线辐射体也可以仅在第一天线辐射体120、第二天线辐射体130和第三天线辐射体140中切换。相应地，如果是左手习惯的用户，则第二天线辐射体130会被握持，此时，第一低频信号的发射可以仅在第一天线辐射体120、第三天线辐射体140和第四天线辐射体150之间切换。可以理解，由于第一天线辐射体120、第二天线辐射体130、第三天线辐射体140和第四天线辐射体150的布局覆盖了电子设备的两条长边及一条短边，无论是横屏状态还是竖屏状态，均至少有一支天线辐射体不会被手持遮挡，从而确保了低频频段信号发射和接收的稳定性。
在一种实施方式中，在电子设备100被配置为支持第一低频信号和第二低频信号的ENDC双连接时，第一天线辐射体120、第二天线辐射体130、第三天线辐射体140和第四天线辐射体150中的其中一者被配置为支持第一低频信号的发射和主集接收，第一天线辐射体120、第二天线辐射体130、第三天线辐射体140和第四天线辐射体150中剩余三支个天线辐射体中的一者被配置为支持第二低频信号的发射和主集接收。第一天线辐射体120、第二天线辐射体130、第三天线辐射体140和第四天线辐射体150中剩余的两个天线辐射体中的一者被配置为同时支持第一低频信号和第二低频信号的分集接收；或者，剩余的两个天线辐射体中的一者被配置为支持第一低频信号的分集接收，另一者被配置为支持第二 低频信号的分集接收。
以第一低频信号为N28频段信号，第二低频信号为B20频段信号为例，当电子设备100被配置为支持第一低频信号和第二低频信号的ENDC双连接时，第二天线辐射体130可以被配置为支持N28频段信号的发射和主集接收，第三天线辐射体140可以被配置为支持B20频段信号的发射和主集接收，第四天线辐射体150可以被配置为同时支持N28频段信号和B20频段信号的分集接收。如此，可以选择三支辐射效率更高的辐射体来实现N28频段和B20频段的三天线EN-DC。当然，N28频段信号和B20频段信号的分集接收也可以分别由两支天线辐射体实现，比如第四天线辐射体150被配置为支持N28频段信号的分集接收，第一天线辐射体120被配置为支持B20频段信号的分集接收。可以理解的是，支持第一低频信号的发射和主集接收的辐射体，以及支持第二低频信号的发射和主集接收的辐射体被配置为可在第一天线辐射体120、第二天线辐射体130、第三天线辐射体140和第四天线辐射体150之间切换。例如，可以选择辐射效率更高的辐射体来支持第一低频信号及第二低频信号的发射和主集接收，从而保证低频频段更好的发射性能。

参考图5，在一种实施方式中，电子设备100还包括第八天线辐射体191，第八天线辐射体191可以是设置于电子设备100内部的支架天线辐射体，其可以设置于电子设备100内部靠近第六天线辐射体170的位置。采用支架天线来实现八天线辐射体191，可以弥补电子设备100边框位置有限而无法设置所需要的数量的天线辐射体的缺陷。同时，将第八天线辐射体191设置于电子设备的顶部区域，可以降低竖屏状态下的手握影响。
在一种实施方式中，电子设备100还包括第九馈源F9、第十馈源F10及第十一馈源F11。第一天线辐射体120还设置有第一超高频馈电点124。第一超高频馈电点124设置于第一低频馈电点122靠近第五天线辐射体160的一侧。第九馈源F9与第一超高频馈电点124连接，用于向第一天线辐射体120馈入超高频频段的激励信号。第六天线辐射体170还设置有第二超高频馈电点175，第二超高频馈电点175设置于第五接地点174背离第四接地点173的一侧。第十馈源F10与第二超高频馈电点175连接，用于向第六天线辐射体170馈入超高频频段的激励信号。第十一馈源F11与第八天线辐射体191连接，用于向第八天线辐射体191馈入超高频频段的激励信号。此外，第七馈源F7还用于向第六天线辐射体170馈入超高频频段的激励信号，第八馈源F8还用于向第七天线辐射体180馈入超高频频段的激励信号。
其中，第一天线辐射体120、第六天线辐射体170、第七天线辐射体180和第八天线辐射体191被配置为支持超高频频段信号的发射和/或接收。在一种实施方式中，第六天线辐射体170朝向第五天线辐射体160的部分被配置为第一超高频辐射体。第一超高频辐射体至少包括第四接地点173靠近第五天线辐射体160一侧的部分第六天线辐射体170。第七天线辐射体180朝向第三天线辐射体140的部分被配置为第二超高频辐射体。第二超高频辐射体至少包括第二匹配点183靠近第三天线辐射体140一侧的部分第七天线辐射体180。第一天线辐射体120朝向第五天线辐射体160的部分被配置为第三超高频辐射体。第三超高频辐射体至少包括第一超高频馈电点124靠近第五天线辐射体160一侧的部分第一天线辐射体120。第六天线辐射体170朝向第七天线辐射体180的部分被配置为第四超高频辐射体。第四超高频辐射体至少包括第二超高频馈电点175朝向第七天线辐射体180一侧的部分第六天线辐射体170。第八天线辐射体191被配置为第五超高频辐射体。

参考图7，在一种实施方式中，第一超高频辐射体、第二超高频辐射体、第三超高频辐射体和第四超高频辐射体被配置为支持第一超高频信号的发射和/或接收；第一超高频辐射体、第二超高频辐射体、第三超高频辐射体和第五超高频辐射体被配置为支持第二超高频信号的发射和/或接收。例如，第一超高频信号可以是NR的N77/N78频段信号，第二超高频信号可以是NR的N79频段信号。
第一超高频辐射体、第二超高频辐射体、第三超高频辐射体和第四超高频辐射体中的任意两者被配置为支持第一超高频信号的发射和主集接收，其余两者被配置为支持第一超高频信号的分集接收。在一种实施方式中，支持第一超高频信号的发射和主集接收的辐射体被配置为可在第一超高频辐射体、第二超高频辐射体、第三超高频辐射体和第四超高频辐射体之间切换。
以NR的N77/N78频段信号为例，第一超高频辐射体可被配置为支持N77/N78频段信号的发射和主集接收，第二超高频辐射体可被配置为支持N77/N78频段信号的MIMO发射及主集MIMO接收，第三超高频辐射体可被配置为支持N77/N78频段信号的分集接收，第四超高频辐射体可被配置为支持N77/N78频段信号的分集MIMO接收。如此，可以实现N77/N78频段信号的2*2MIMO发射及4*4MIMO接收。可以理解，为确保N77/N78频段信号的发射性能，可以在第一超高频辐射体、第二超高频辐射体、第三超高频辐射体和第四超高频辐射体中选择辐射效率更高的两支辐射体来分别支持N77/N78频段信号的发射和主集接收、MIMO发射及主集MIMO接收。

基于上述关于低频、中高频及超高频的实施例可以看出，本申请实施例提供的电子设备100，无论是低频天线辐射体、中高频天线辐射体及超高频天线辐射体，均采用了至少部分环绕电子设备100的天线布局，且低频天线辐射体、中高频天线辐射体及超高频天线辐射体整体上成360°环绕布局，从而实现各频段信号的360°覆盖，无论电子设备处于竖屏使用状态，还是横屏使用状态，均可以确保各频段至少有一支天线辐射体不会受到握持的影响，结合本申请实施例提供的天线切换逻辑，即可保证各种使用场景下低频、中高频及超高频频段的天线性能。
参考图8，在一种实施方式中，电子设备还包括第十二馈源F12。七天线辐射体180还设置有第一短距离频段馈电点185，第一短距离频段馈电点185设置于第三匹配点184靠近第六天线辐射体170的一侧。第十二馈源F12与第一短距离频段馈电点185连接，用于向第七天线辐射体180馈入第一短距离频段的激励信号。此外，第四馈源F4还用于向第四天线辐射体150馈入第一短距离频段的激励信号，第八馈源F8还用于向第七天线辐射体180馈入第一短距离频段的激励信号。
在一种实施方式中，第四天线辐射体150朝向第三天线辐射体140的部分被配置为第一短距离辐射体；第七天线辐射体180朝向第三天线辐射体140的部分被配置为第二短距离辐射体；第七天线辐射体180朝向第六天线辐射体170的部分被配置为第三短距离辐射体。其中，第一短距离辐射体、第二短距离辐射体和第三短距离辐射体被配置为支持第一频段短距离信号的发射和/或接收。第一频段短距离信号可以是Wi-Fi 2.4G频段的信号或者蓝牙信号。在一种实施方式中，第一短距离辐射体，第二短距离辐射体和第三短距离辐射体中的任意两者被配置为支持第一频段短距离信号的2*2MIMO。如此，电子设备100可以在第一短距离辐射体，第二短距离辐射体和第三短距离辐射体中选择辐射效率更高的两支辐射体来实现Wi-Fi 2.4G频段或者蓝牙频段信号的2*2MIMO。
参考图9，在一种实施方式中，电子设备100还包括第九天线辐射体192和第十三馈源F13。第九天线辐射体192可以是设置于电子设备100内部的支架天线辐射体，其可以设置于电子设备内部靠近第三天线辐射体140和第七天线辐射体180之间形成的缝隙的一侧，如图9所示；也可以设置于电子设备 100内部靠近第一天线辐射体120与第五天线辐射体160之间形成的缝隙的一侧，如图10所示。如此设置，即让第九天线辐射体192的至少部分与其外围的天线辐射体之间形成的缝隙相对，可以降低外围天线辐射体对第九天线辐射体192辐射性能的影响，从而提升第九天线辐射体192的辐射性能。第十三馈源F13与第九天线辐射体192连接，用于向第九天线辐射体192馈入第二短距离频段的激励信号。此外，第十馈源F10还用于向第六天线辐射体170馈入第二短距离频段的激励信号。
在一种实施方式中，第六天线辐射体170朝向第七天线辐射体180的部分被配置为第四短距离辐射体；第九天线辐射体192被配置为第五短距离辐射体。
参考图11，在一种实施方式中，第九天线辐射体192也可以通过共用第三天线辐射体140来实现，即无需在电子设备100内部额外设置第九天线辐射体192。例如，可以在第三天线辐射体140上设置第二短距离频段馈电点145，第二短距离频段馈电点145设置于第三低频馈电点142靠近第七天线辐射体180的一侧。第十三馈源F13与第二短距离频段馈电点145连接，用于向述第三天线辐射体140馈入第二短距离频段的激励信号。此时，第三天线辐射体140朝向第七天线辐射体180的部分被配置为第五短距离辐射体。第四短距离辐射体和第五短距离辐射体被配置为支持第二频段短距离信号的发射和/或接收。第二频段短距离信号可以是Wi-Fi 5G频段的信号或者Wi-Fi 6G频段的信号。在一种实施方式中，第四短距离辐射体和第五短距离辐射体被配置为支持第二频段短距离信号的2*2MIMO。
参考图12，在一种实施方式中，基于图10所示的实施方式基础上，即第六天线辐射体170朝向第七天线辐射体180的部分被配置为第四短距离辐射体，第九天线辐射体192被配置为第五短距离辐射体的基础上，可以进一步利用第三天线辐射体140来实现短距离通信。电子设备100可以进一步包括第十四馈源F14，第十四馈源F14与第三天线辐射体140的连接方式可以参考图11实施例中第十三馈源F13。此时，第三天线辐射体140朝向第七天线辐射体180的部分被配置为第六短距离辐射体，从而在电子设备100内部实现Wi-Fi 5G/6G的三天线架构。进一步地，第四短距离辐射体、第五短距离辐射体和第六短距离辐射体中的任意两者被配置为支持支持第二频段短距离信号的2*2MIMO。如此，电子设备100可以在第四短距离辐射体、第五短距离辐射体和第六短距离辐射体中选择辐射效率更高的两支辐射体来实现Wi-Fi 5G/6G频段信号的2*2MIMO。
参考图13，在一种实施方式中，第二天线辐射体130和第四天线辐射体150的位置可相对于电子设备100长度方向(即平行于第一长边111和第二长边113的方向)的中轴线镜像。镜像之后的第四天线辐射体150位于第一天线辐射体120和第二天线辐射体130之间。由于位于第一短边115的第二天线辐射体130长于位于第一短边115的第三天线辐射体140，在图1所示的实施例中，第二天线辐射体130和第四天线辐射体150之间的缝隙S0相对靠近第二长边113，当电子设备100处于右手握持状态时，该缝隙S0很容易被右手遮挡，从而影响电子设备100在右手握持下的天线性能。通过将第二天线辐射体130和第四天线辐射体150的位置相对于电子设备100长度方向的中轴线镜像，可以让第二天线辐射体130和第四天线辐射体150之间的缝隙S0相对于图1所示实施例的方案，更远离第二长边113，从而提升电子设备100处于右手握持状态下的天线性能。
参考图14，在一种实施方式中，在图13所示实施例的基础上，还可以将第四天线辐射体150和第一天线辐射体120之间形成的缝隙S1设置得更靠近第一短边115。即第四天线辐射体150和第一天线辐射体120之间形成的缝隙S1相对于第二天线辐射体130和第三天线辐射体140之间形成的缝隙S2更靠近第一短边115。此时，原来的第一天线辐射体120变长，而原来的第四天线辐射体150变短，较短的第四天线辐射体150可能不足以实现低频频段的谐振。因此，需要将原本由第四天线辐射体150实现的低频天线辐射体至少部分更改为由第一天线辐射体120实现。此时，第四低频馈电点152设置于第一辐射体120上，且位于第一接地点123背离第一低频馈电点122的一侧，第四馈源F4通过第四低频馈电点152连接到第一天线辐射体120。在该实施方式中，第一天线辐射体120朝向第四天线辐射体150的部分(至少包括第一接地点123背离第一低频馈电点122一侧的部分第一天线辐射体120)和第四天线辐射体150朝向第一天线辐射体120的部分(至少包括第三接地点153背离第二中高频馈电点155一侧的部分第四天线辐射体150)共同被配置为支持第一低频信号、第二低频信号和第一短距离信号的发射和/或接收。当电子设备100处于口袋使用场景下时，通常是将第二短边117朝向口袋内部， 而第一短边115朝向口袋外部放置。此时，如果缝隙S1远离第一短边115，则该缝隙S1极有可能受到口袋遮挡，从而影响电子设备在Wi-Fi 2.4G频段和蓝牙频段的通信性能。图14所示的电子设备100，通过将缝隙S1设置得更靠近第一短边115，且将原本由第四天线辐射体150实现的低频天线辐射体至少部分更改为由第一天线辐射体120实现，可以有效提升电子设备在口袋使用场景下的Wi-Fi 2.4G频段和蓝牙频段的通信性能。
参考图15，在一种实施方式中，电子设备100还包括第十五馈源F15。五天线辐射体160还设置有第一定位馈电点165，第一定位馈电点165设置于第五匹配点164靠近第六天线辐射体170的一侧。第十五馈源F15与第一定位馈电点165，用于向第五天线辐射体160馈入第一定位频段的激励信号。此外，第十二馈源F12还用于向第七天线辐射体180馈入第二定位频段的激励信号。在一种实施方式中，第五天线辐射体160朝向第六天线辐射体170的部分(至少包括第一定位馈电点165背离第五匹配点164一侧的部分第五天线辐射体160)被配置为支持第一频段定位信号的接收，第七天线辐射体180朝向第六天线辐射体170的部分(至少包括第一短距离频段馈电点185背离第三匹配点184一侧的部分第七天线辐射体180)被配置为支持第二频段定位信号的接收。其中，第一频段定位信号可以为GPS-L5频段的信号，第二频段定位信号可以为GPS-L1频段的信号。通过复用第五天线辐射体160来实现独立的GPS-L5天线，实现了GPS-L5与四支低频天线的共存，从而使得电子设备100可以完美兼容低频四路接收，低频三天线或者四天线EN-DC及GPS-L5，以满足某些地区运营商对这三种天线工作模式的需求。
参考图16，在一种实施方式中，电子设备100还包括Sar传感器101。第一匹配电路M1、第二匹配电路M2、第三匹配电路M3、第四匹配电路M4和第五匹配电路M5均包括电容器件C，或者如图16所示的，将第一匹配电路M1、第二匹配电路M2、第三匹配电路M3、第四匹配电路M4和第五匹配电路M5分别通过电容器件C与各自对应的辐射体连接，只需保证电容器件C设置于第二天线辐射体130、第五天线辐射体160和第七天线辐射体180的接地路径上即可，这些电容器件C用于隔离直流信号，并允许高频信号通过。如此，则可以将第二天线辐射体130、第五天线辐射体160和第七天线辐射体180配置为Sar传感器101的感应枝节，从而在电子设备10的左上角、右上角、右下角都可以合入Sar检测功能，一方面能检测电子设备100的6个面(前、后、左、右、上和下)的Sar值，另一方面也能够覆盖所有存在中高频段天线的Sar热点区域，进而可以根据各热点区域对应的Sar值来选择是否需要对相应的中高频段天线进行功率回退，以满足人体辐射指标要求。可以理解的是，当第八馈源F8对应的第四中高频辐射体的辐射性能较差时，且电子设备100左上角天线的Sar值较小时，可以选择性地将第二匹配电路M2和第三匹配电路M3可被配置为形成第七天线辐射体到电子设备的参考地的直接接地路径，从而可以提升第四中高频辐射体的辐射性能。
本申请实施例提供的电子设备100，通过360°环绕式天线设计，使得无论是低频频段、中高频频段还是超高频频段的天线均实现了环绕式的覆盖，并结合智能天线切换，可以将各频段对应的天线辐射体中，辐射效率更高的天线辐射体配置为对应频段的发射天线，从而可以提升各频段下的通信性能。同时，在实现5G低频频段信号四路接收，提升5G低频频段的利用率及下行速率的同时，兼容低频三天线或者四天线EN-DC，可以很好地满足部分地区因5G基站部署较为缓慢而对EN-DC的强制需求，确保了在第一低频频段的网络覆盖不完善的地区，电子设备可以充分利用第二低频频段的网络资源而实现第一低频频段与第二低频频段的EN-DC，从而进一步保证电子设备稳定可靠的低频通信性能。
参考图17给出了电子设备100的常见操作模式，其中竖屏操作模式包括如图17(a)所示的左手握持操作模式和如图17(b)所示的右手握持操作模式，横屏操作模式包括如图17(c)所示的双手握持操作模式。可以理解的是，无论是在哪种操作模式下，低频频段、中高频频段和超高频频段均至少有一支天线辐射体不会被握持遮挡，从而确保本申请实施例提供的电子设备100在不同频段和不同操作模式下均能够提供良好的天线性能，保证电子设备无线通信功能的稳定性及可靠性。
以上实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。
