由此可见，本申请的天线组件10可实现ENDC，可支持同时支持4G无线接入网与5G-NR，因此，本申请实施方式提供的天线组件10可提升4G及5G的传输带宽，以及提升上行下行速率，具有较好的通信效果。此外，本申请实施方式提供的天线组件10可实现CA，也具有较好的通信效果。
当所述天线组件10还包括第二辐射体120、第三匹配电路M3、第四匹配电路M4及第三信号源S3时，所述天线组件10还包括第三天线10c(请一并参阅图32，图32为一实施方式中天线组件中第三天线的示意图)，换而言之，所述第三天线10c包括第二辐射体120、第三匹配电路M3、第四匹配电路M4及第三信号源S3。
所述第一天线10a及所述第二天线10b共用一个第一辐射体110，所述第一天线10a工作时可利用 所述第一辐射体110收发电磁波信号，所述第二天线10b工作时还利用所述第一辐射体110收发电磁波信号，从而使得所述天线组件10在较少的辐射体的情况下，仍然可工作在较宽的频段。
当所述天线组件10包括第一天线10a、第二天线10b及第三天线10c时，可实现三个天线共口径。第三天线10c工作时不但可以利用所述第二辐射体120收发电磁波信号，还可利用所述第一辐射体110收发电磁波信号，从而使得所述第三天线10c可工作在较宽的频段。此外，由于所述第一天线10a及第二天线10b工作时不但可以利用第一辐射体110并且可以利用第二辐射体120收发电磁波信号，所述第三天线10c工作时不但可以利用第二辐射体120还可利用第一辐射体110，因此，实现了天线组件10中辐射体的复用，因此，有利于减小所述天线组件10的尺寸。由上述分析可知，所述天线组件10的尺寸较小，当所述天线组件10应用于电子设备1中时，便于与电子设备1中的其他器件堆叠。
