可以通过改变第二辐射体的长度以改变第二辐射体辐射第二射频信号的工作频段。示例性的，当第二辐射体用于辐射GPS L1频段的第二射频信号时，其第二辐射体的长度可定义为第一长度；当第二辐射体用于辐射GPS L5频段的第二射频信号时，其第二辐射体的长度可定义为第二长度。其中，第二长度大于第一长度。当然，为了使第二辐射体能够辐射GPS L5频段的第二射频信号，在辐射GPS L1频段的第二射频信号的基础上，除了需要增加第二辐射体的长度，还需要对应调整第二滤波电路213及第二馈电电路223中个器件的参数。
需要说明的是，辐射体越长就能够覆盖更低的频段，高频段反而对辐射体的尺寸要求不高。第一辐射体和第二辐射体的长度可根据第一射频信号和第二射频信号的工作频段进行调整。
可以理解地是，第一辐射体还可以用于实现对第一射频信号的接收，第二辐射体也可以实现对第二射频信号的接收，因此，通过第一辐射体和第二辐射体可实现对第一射频信号和第二射频信号的输入(接收)和输出(辐射)。

参考图4，在其中一个实施例中，所述切换模块230包括开关单元231和多个第三电容(C3、C4、C5、C6)。其中，开关单元231包括控制端和多个选择端，所述控制端分别与所述第一馈点S1、第一滤波电路211连接；所述选择端经所述第三电容接地。
参考图5，在其中一个实施例中，可以将上述实例中切换模块230的第三电容替换为第三电感。具体的，该切换模块230可包括开关单元231和多个第三电感(L3、L4、L5、L6)。开关单元231包括控制端和多个选择端，所述控制端分别与所述第一馈点S1、第一滤波电路211连接；所述选择端经所述第三电感接地。
其中，开关单元231的选择端的数量可以根据第一辐射体所能够辐射的工作频段的数量来设定。具体的，开关单元231可以为单刀多掷开关，其中，单刀多掷开关的动端可以作为开关单元231的控制端，单刀多掷开关的不动端可以作为开关单元231的选择端。其中，单刀多掷开关的每个不动端均连接一个电容，且每个电容的电容值均不相同。
需要说明的是，该开关单元231也可包括多个单刀单掷开关、多个单刀双掷开关、多个电子开关管等。其中，电子开关管可以为MOS管、晶体管等。在本申请实施例中，对开关单元231的具体组成器件不做进一步的限定，其满足符合对多个第三电容或多个第三电感的切换选择条件即可。
当该天线组件的第一辐射体需要辐射不同工作频段的第一射频信号时，可以控制开关单元231选择导通不同的调谐通路，以改变调谐通路中第三电容或第三电感的大小进而调节工作谐振频率以向第一导电枝节113馈入可切换的第一电流信号，来实现切换不同的工作频段。
如图6所示，通过在第一馈电电路221和第一滤波电路211之间设置该切换模块230，可以用于切换第一射频信号中的多个工作频段(例如，MHB、N78、N79工作频段)，并同时保持第二射频信号(例如，GPS L1)的谐振频率始终不变，同时，各个工作频段(例如，工作频段B1、B3、B40、B41、N78、N79)的辐射效率和系统效率均满足通信要求，从而实现蜂窝网和GPS定位同时工作不相互影响。
需要说明的是，谐振频率7-13％范围内的频率可以理解为天线的工作带宽。例如，天线的谐振频率为1800MHz，工作带宽为谐振频率的10％，则天线的工作频段为1620MHz-1980MHz。
如图7所示，在其中一个实施例中，所述第一导电枝节113和所述第一馈电电路221之间还设有用于调节所述第一射频信号的第一匹配电路241；其中，第一匹配电路241可以用于调节第一辐射体的输入阻抗，以提高第一辐射体的传输性能。
所述第二导电枝节115和所述第二馈电电路223之间还设有用于调节所述第二射频信号的第二匹配电路243；其中，第二匹配电路243可以用于调节第二辐射体的输入阻抗，以提高第二辐射体的传输性能。
具体的，第一匹配电路241和第二匹配电路243可包括电容和/或电感等的组合。在本申请实施例中，对第一匹配电路241和第二匹配电路243的具体组成形式不做进一步的限定。
需要说明的是，第一馈点S1可靠近缝隙111设置，第二馈点S2也可靠近缝隙111设置。可以理解，第一馈点S1的具体位置与第一匹配电路241相关联，也即，第一馈点S1的具体位置可以根据第一匹配电路241来设置，相应的，第二馈点S2的具体位置与第二匹配电路243相关联，也即，第二馈点S2的具体位置可以根据第二匹配电路243来设置。
在其中一个实施例中，通过在所述导电边框110上设置所述缝隙111，从而将所述导电边框110分割为第一导电枝节113和第二导电枝节115，并在所述第一导电枝节113靠近所述缝隙111的位置馈入用于激励所述第一导电枝节113谐振于LTE的MHB频段或5G NR的N78、N79频段的第一电流信号，以及在所述第二导电枝节115靠近所述缝隙111的位置馈入用于 激励所述第二导电枝节115谐振于GPS L1或GPS L5频段的第二电流信号，从而实现双导电枝节的共口径天线设计，使得GPS、MHB、N78和N79共用一个缝隙，提高缝隙和整机空间利用率。
在其中一个实施例中，导电边框110上开设的缝隙111的数量为多个。示例性的，以缝隙为两个为例进行说明。两个缝隙包括第一缝隙和第二缝隙，其中，第一缝隙和第二缝隙可以将导电边框110分割为独立的第一导电枝节、第二导电枝节和第三导电枝节，其中，在每一所述导电枝节上均可对应设置馈点和回地点。其中，第一导电枝节上可集成用于辐射第一射频信号的第一辐射体，第二导电枝节上可集成用于辐射第二射频信号的第二辐射体，第三导电枝节上可集成用于辐射第三射频信号的第三辐射体。其中，第三射频信号可以为WIFI(WIreless-FIdelity)信号、蓝牙(Bluetooth)信号。具体的，其中，WIFI信号的工作频段可包括2.4GHz和5GHz，Bluetooth信号的工作频段可包括2.4GHz。
进一步的，每个馈点均可经导电弹片或螺钉连接至滤波电路，并由其滤波电路连接至对应的馈电电路。每一馈电电路可经该滤波电路、导电弹片或螺钉、馈点将馈电电流馈入至对应的导电枝节，以使馈点与回地点之间导电枝节(辐射体)上激励出四分之一或其他模式的电流，从而产生辐射，即可辐射不同的射频信号。
依此类推，当导电边框110上设置有N(N>2)条缝隙111时，可以将导电边框110分割为N+1个独立的导电枝节，同时可对应设置N+1个滤波电路、馈电电路，也在N+1个独立的导电枝节上对应集成N+1个辐射体，看用于辐射N+1个射频信号，且每个射频信号的工作频段不同。
本申请实施例还提供一种电子设备10，该电子设备10包括基板130以及如上述任一实施例中的天线组件；其中，所述基板130容置于所述导电边框110围合形成的空腔内，所述滤波模块210、馈电模块220设置在所述基板130上。
当该天线组件应用在电子设备10中时，第一导电枝节113和第二导电枝节115共用同一缝隙111以同时实现对第一射频信号和第二射频信号的辐射，可以提高缝隙111和电子设备10中导电边框110的空间利用率。同时，可以不必再单独设计天线辐射体，减少了手机的厚度。
示例性的，由于采用共口径天线设计，使得GPS、MHB、N78和N79共用一个缝隙，从而可以将该第一辐射体和第二辐射体集成在电子设备10的第一边框或第三边框，以提高顶部边框或底部边框的利用率，进而可以减轻将天线组件集成在侧边框的压力，以减小侧边框的剖面高度，可以将侧边框的剖面高度缩小至1mm以内。其中，侧边框的剖面高度可以理解即导电边框110在电子设备10厚度方向的金属宽度，导电边框110的剖面高度是影响其辐射效率的主要因素之一。在曲面屏的侧面弯曲弧度越来越大的背景下，侧边框的剖面高度受限，从而使得天线净空大幅度减小，通过采用本发明实施方式中提供的共口径天线设计，可以在顶部边框或底部边框来集成天线组件，保证天线具有足够的净空，并通过切换电路的设计，在顶部或底部边框有限的辐射体长度下，满足多频段、多天线的设计需求。
本申请所使用的对存储器、存储、数据库或其它介质的任何引用可包括非易失性和/或易失性存储器。合适的非易失性存储器可包括只读存储器(ROM)、可编程ROM(PROM)、电可编程ROM(EPROM)、电可擦除可编程ROM(EEPROM)或闪存。易失性存储器可包括随机存取存储器(RAM)，它用作外部高速缓冲存储器。作为说明而非局限，RAM以多种形式可得，诸如静态RAM(SRAM)、动态RAM(DRAM)、同步DRAM(SDRAM)、双数据率SDRAM(DDR SDRAM)、增强型SDRAM(ESDRAM)、同步链路(Synchlink)DRAM(SLDRAM)、存储器总线(Rambus)直接RAM(RDRAM)、直接存储器总线动态RAM(DRDRAM)、以及存储器总线动态RAM(RDRAM)。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述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 此而理解为对本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。因此，本申请专利的保护范围应以所附权利要求为准。
