在本文中提及“实施例”或“实施方式”意味着，结合实施例或实施方式描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
本申请提供了一种天线组件10。所述天线组件10可应用于电子设备1中，所述电子设备1包括但不仅限于为手机、互联网设备(mobile internet device，MID)、电子书、便携式播放站(Play Station Portable,PSP)或个人数字助理(Personal Digital Assistant，PDA)等具有通信功能的电子设备1。
请参阅图1，图1为本申请一实施方式提供的天线组件的示意图。所述天线组件10包括第一天线110及第二天线120。所述第一天线110包括第一辐射体111、第一信号源112及第一匹配电路113。所 述第一辐射体111具有第一馈电点1113，所述第一信号源112电连接所述第一匹配电路113至所述第一馈电点1113。所述第二天线120包括第二辐射体121、第三辐射体125、第二信号源122及第二匹配电路123。所述第二辐射体121与所述第一辐射体111间隔设置且相互耦合，所述第二辐射体121具有第二馈电点1213，所述第二信号源122电连接所述第二匹配电路123至所述第二馈电点1213，且所述第二信号源122还电连接所述第二匹配电路123至所述第三辐射体125，所述第一天线110及所述第二天线120共同作用以实现至少第一频段范围、第二频段范围及第三频段范围的电磁波信号的收发。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。所述天线组件10包括第一天线110及第二天线120并不排除所述天线组件10还包括第一天线110及第二天线120之外的其他天线。
所谓信号源，是指产生激励信号的器件，当所述第一天线110用于接收电磁波信号时，所述第一信号源112产生第一激励信号，所述第一激励信号经由所述第一匹配电路113加载到所述第一馈电点1113上，以使得所述第一辐射体111辐射电磁波信号。相应的，当所述第二天线120用于接收电磁波信号时，所述第二信号源122产生第二激励信号，所述第二激励信号经由所述第二匹配电路123加载到第二馈电点1213上，以使得所述第二辐射体121收发电磁波信号，且使得所述第三辐射体125收发电磁波信号。
所述第一辐射体111可以为柔性电路板(Flexible Printed Circuit，FPC)天线辐射体或者为激光直接成型(Laser Direct Structuring，LDS)天线辐射体、或者为印刷直接成型(Print Direct Structuring，PDS)天线辐射体、或者为金属枝节。相应地，所述第二辐射体121可以为FPC天线辐射体或者为LDS天线辐射体、或者为PDS天线辐射体、或者为金属枝节。可以理解地，所述第三辐射体125可以为FPC天线辐射体或者为LDS天线辐射体、或者为PDS天线辐射体、或者为金属枝节。所述第一辐射体111、所述第二辐射体121及所述第三辐射体125的类型可以相同，也可以不同。
本实施方式提供的天线组件10中，所述第二辐射体121与所述第一辐射体111间隔设置且相互耦合，也即所述第一辐射体111与所述第二辐射体121共口径，由于所述第一辐射体111和第二辐射体121的耦合作用，所述第一天线110工作时不但利用所述第一辐射体111收发电磁波信号，还利用所述第二辐射体121收发电磁波信号，从而使得所述第一天线110可工作在较宽的频段。同样地，第二天线120工作时不但可以利用所述第二辐射体121收发电磁波信号，还可利用所述第一辐射体111收发电磁波信号，从而使得所述第二天线120可工作在较宽的频段。此外，由于所述第一天线110工作时不但可以利用第一辐射体111并且可以利用第二辐射体121收发电磁波信号，所述第二天线120工作时不但可以利用第二辐射体121还可利用第一辐射体111，因此，实现了天线组件10中辐射体的复用，也实现了空间的复用，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。此外，本实施方式提供的天线组件10中第二天线120中的第二辐射体121和第三辐射体125共用第二匹配电路123，可使得所述第二天线120收发电磁波信号时不但可利用第二辐射体121收发电磁波信号，还可利用第三辐射体125收发电磁波信号，因此，所述第二天线120可支持较多频段的电磁波信号的收发。
需要说明的是，所述第二辐射体121与所述第一辐射体111间隔设置且相互耦合，具体是指，通过第一辐射体111和第二辐射体121的“口对口”设计，又叫共口径设计，来实现的第一辐射体111与所述第二辐射体121的相互耦合。这里“口对口”中的“口”为天线的辐射口径，即，所述第一天线辐射体111与所述第二天线辐射体121的辐射口径相对。所述第一辐射体111和第二辐射体121的共口径设计可以提升第一天线110和第二天线120的复用率，通过“口对口”的第一辐射体111和第二辐射体121的相互耦合来激励出更多的谐振模式(也称为谐振模态)，从而可以利用更少的天线枝节来实现更多的谐振模式。
在本实施方式中，所述第一天线110用于实现第一频段范围的电磁波信号的收发，所述第二天线120用于实现第二频段范围及第三频段范围的电磁波信号的收发，其中，第一频段范围包括低频(Lower Band，LB)频段，第二频段范围包括中高频(Middle High Band，MHB)频段，第三频段范围包括超高频(Ultra High Band，UHB)频段。
所谓LB频段，是指频率低于1000MHz的频段；所谓MHB频段的范围为：1000MHz-3000MHz；所谓UHB频段的范围为：3000MHz-6000MHz。
可以理解地，在其他实施中，所述第一天线110及所述第二天线120还支持其他频段范围的电磁波信号的收发，其他实施方式中所述第一天线110及所述第二天线120支持其他频段的电磁波信号的情况稍后详细介绍如下。

在接下来的实施方式中，以所述第一天线110用于实现第一频段范围的电磁波信号的收发，所述第二天线120用于实现第二频段范围及第三频段范围的电磁波信号的收发为例进行介绍。
在本实施方式中，所述天线组件10具有第一谐振模式、第二谐振模式、第三谐振模式及第四谐振模式，以覆盖所述第二频段范围及所述第三频段范围的电磁波信号的收发。
其中，所述第一谐振模式、所述第二谐振模式、所述第三谐振模式及所述第四谐振模式中的至少一个谐振模式由所述第三辐射体产生(后面讲到的第四谐振模式)，至少另一个谐振模式由部分所述第一辐射体111耦合来自第二辐射体121的信号耦合产生(即后面讲到的第二谐振模式)。稍后将结合天线组件10的仿真示意图对各个谐振模式进行介绍。

请参阅图22，图22为另一实施方式中电子设备的位置示意图。本实施方式中的电子设备1包括首尾依次相连的第一侧边11、第二侧边12、第三侧边13、及第四侧边14。所述第一侧边11与所述第三侧边13为电子设备1的短边，所述第二侧边12及所述第四侧边14为所述电子设备1的长边。所述第一侧边11与所述第三侧边13相对且间隔设置，所述第二侧边12与所述第四侧边14相对且间隔设置，所述第二侧边12分别与所述第一侧边11及所述第三侧边13弯折相连，所述第四侧边14分别与所述第一侧边11及所述第三侧边13弯折相连。所述第一侧边11与所述第二侧边12的连接处、所述第二侧边12与所述第三侧边13的连接处、所述第三侧边13与所述第四侧边14的连接处、所述第四侧边14与所述第一侧边11的连接处均形成电子设备1的角A。所述第一辐射体111及所述第二辐射体121可对应所述电子设备1中的任意一个角设置，需要注意的是，所述第一辐射体111与所述第二辐射体121均对应所述电子设备1的同一个角设置。当所述第一辐射体111及所述第二辐射体121对应所述电子设备1的角设置时，所述第一天线110及所述第二天线120的效率较高。可以理解地，在本实施方式中，以所述第一侧边11及所述第三侧边13为所述电子设备1的短边，且所述第二侧边12及所述第四侧边14为电子设备1的长边为例进行示意，在其他实施方式中，所述第一侧边11、所述第二侧边12、所述第三侧边13、及所述第四侧边14长度相等。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型，这些改进和润饰也视为本申请的保护范围。
