技术领域
本发明实施例涉及通信技术领域，尤其涉及一种天线结构及电子设备。
背景技术
当前移动终端金属质感成为主流，显示屏占比也逐步增大，天线谐振臂的设计空间未来越小。尤其是金属外形移动终端，天线谐振臂的形状极其简单，不同于柔性电路板(Flexible Printed Circuit，FPC)天线或激光成型(Laser-Direct-structuring，LDS)天线，其天线辐射臂可以有多种变化。于是出现了主天线与全球定位系统(Global Positioning System，GPS)天线等其他天线共用辐射单元的天线形式，对于传统的方案，大部分是在天线本体上增加加载单元，形成双谐振或者多谐振。
如图1所示，可以通过天线辐射体加载电容实现主天线低频与GPS频段双谐振，天线包括：辐射体101和加载电容102。但通过加载电容匹配出双谐振的方式会影响低频的性能，引入损耗，降低低频的效率。
发明内容
本发明实施例提供一种天线结构及电子设备，以解决现有技术中的天线结构在实现低频与位置服务频段双谐振时，影响低频的性能，引入损耗，降低低频的效率的问题。
为了解决上述技术问题，本发明是这样实现的：
第一方面，本发明的实施例提供了一种天线结构，包括：
信号源；
天线辐射体，所述天线辐射体设置有第一馈电点、第二馈电点以及接地 点；
其中，所述第一馈电点通过馈线与所述信号源电连接，所述第二馈电点通过LC串联电路与所述信号源电连接，所述接地点接地；
其中，所述LC串联电路传输第一频段的信号时，所述LC串联电路等效为短路；所述LC串联电路传输第二频段的信号时，所述LC串联电路的阻抗值为预设阻抗值，所述第一频段为位置服务频段，且高于所述第二频段。
第二方面，本发明的实施例还提供了一种电子设备，包括如上述实施例所述的天线结构。
本发明实施例的上述方案中，天线辐射体上的第一馈电点通过馈线与信号源电连接，天线辐射体上的第二馈电点通过LC串联电路与信号源电连接，天线辐射体的接地点接地；其中，该LC串联电路传输第一频段的信号时，该LC串联电路等效为短路；该LC串联电路传输第二频段的信号时，该LC串联电路的阻抗值为预设阻抗值，第一频段为位置服务频段且高于第二频段，如此，通过在馈电处增加一路LC串联电路的分支，使得该天线结构在第一频段等效为短路，在基本不影响第二频段的情况下，实现第一频段和第二频段的双谐振。
附图说明

需要说明的是，信号源1(或称馈源)可以用于收发信号，提供电磁波能量。
进一步地，信号源1用于收发所述第一频段的信号以及所述第二频段的信号，也就是说，信号源1即馈电为第一频段和第二频段信号的馈电，也就是第一频段的信号和第二频段的信号共用馈电。信号源1通过两个分支连接到天线辐射体2上，其中，一个分支通过馈线6连接到天线辐射体2上，另一个分支通过LC串联电路连接到天线辐射体2上。这里，LC串联电路传输第一频段的信号时，其等效为短路；LC串联电路传输第二频段的信号时，其阻抗值为预设阻抗值，从而能够形成双谐振，而且对第二频段，即低频基本没有影响，降低对低频的损耗，提升低频的效率。
这里，本发明实施例并不限定接地方式，在实际应用中，接地方式可以但不限于包括通过连接金属壳体、主板地或参考地的方式接地。
在一可选地实现方式中，第一频段为位置服务频段，第二频段为低频频段。也就是说，采用上述天线结构，LC串联电路传输位置服务频段的信号时，其等效为短路；LC串联电路传输低频频段的信号时，其阻抗值为预设阻抗值。

需要说明的是，LC串联电路包括串联连接的电感和电容的情况下，基于上述天线结构，LC串联电路传输第二频段的信号时，LC串联电路的阻抗值 为该电容7的电容值。也就是说，LC串联电路等效为电容；LC串联电路传输第一频段的信号时，LC串联电路等效为短路，从而达到一馈两分支双谐振，又相互之间基本不影响的效果。
可选地，所述LC串联电路通过弹片、导电泡棉或螺钉与第二馈电点4导通。当然，其他能够使LC串联电路与第二馈电点4导通的连接方式也可采用，这里不做具体限定。
可选地，所述天线辐射体2为金属体、FPC天线或者LDS天线。
本发明实施例的天线结构，天线辐射体上的第一馈电点通过馈线与信号源电连接，天线辐射体上的第二馈电点通过LC串联电路与信号源电连接，天线辐射体的接地点接地；其中，该LC串联电路传输第一频段的信号时，该LC串联电路等效为短路；该LC串联电路传输第二频段的信号时，该LC串联电路的阻抗值为预设阻抗值，第一频段为位置服务频段，且高于第二频段，如此，通过在馈电处增加一路LC串联电路的分支，使得该天线结构在第一频段等效为短路，在基本不影响第二频段的情况下，实现第一频段和第二频段的双谐振。
本发明实施例还提供一种电子设备，包括如上述实施例所述的天线结构。
需要说明的是，在本文中，术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。此外，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本发明的保护之内。
