技术领域
本公开实施例涉及通信技术领域，尤其涉及一种天线及终端设备。
背景技术
天线是一种电磁转换器件，用于将导线上传播的电信号变换为电磁波，并将电磁波发送至无界媒介(通常是自由空间)中传播，或者接收无界媒介中传播的电磁波，并转为电信号输入导线。由于实现无线通信过程中必须通过天线进行无线信号的接收和发送，因此天线在终端设备(例如：家用电器、手机、可穿戴产品)中的应用非常广泛。
随着通信技术的不断发展，用户对通信速率和通信延迟提出了越来越高的要求，因此无线通信技术逐渐向更高的通信频段和更宽的通信带宽发展。在无线通信技术逐渐向更高的通信频段和更宽的通信带宽发展的同时，终端设备中的天线需要能够支持更高的通信频段以及更宽的通信带宽，而这给终端设备中天线的设计带来了严峻的挑战。目前，终端设备移动终端通信频段主要是3GHz频率以下频段，终端设备在天线设计时基本没有考虑3.3GHz至5GHz的频率特性，因此目前终端设备的天线无法实现3.3GHz至5GHz的有效辐射。
发明内容
本公开实施例提供一种天线及终端设备，用于解决终端设备的天线无法实现3.3GHz至5GHz的有效辐射的问题。
为了解决上述技术问题，本公开是这样实现的：
第一方面，本公开实施例提供了一种天线，包括：天线馈源、第一辐射体、第二辐射体以及参考地；
所述第一辐射体的第一端与所述天线馈源电连接，所述第一辐射体的第二端与所述参考地电连接，所述第二辐射体的第一端浮空，所述第二辐射体的第二端与所述参考地电连接；所述第一辐射体与所述第二辐射体耦合；
所述第一辐射体，用于在所述天线馈源输出的馈源信号以及与所述第二辐射体耦合生成的第一耦合信号的作用下产生第一谐振频率；

其中，所述第一谐振频率的频率范围为第一频段，所述第二谐振频率的频率范围为第二频段，所述第一频段和所述第二频段的组合覆盖3.3GHz至5.0GHz中的所有频率。
第二方面，提供一种终端设备，包括：第一方面所述的天线。
本公开实施例提供的天线包括：天线馈源、第一辐射体、第二辐射体以及参考地，其中，所述第一辐射体的第一端与所述天线馈源电连接，所述第一辐射体的第二端与所述参考地电连接，所述第二辐射体的第一端浮空，所述第二辐射体的第二端与所述参考地电连接；所述第一辐射体与所述第二辐射体耦合；所述第一辐射体，用于在所述天线馈源输出的馈源信号以及与所述第二辐射体耦合生成的第一耦合信号的作用下产生第一谐振频率；所述第二辐射体，用于在与所述第一辐射体耦合产生的第二耦合信号的作用下产生第二谐振频率；由于第一谐振频率的频率范围为第一频段，第二谐振频率的频率范围为第二频段，因此第一辐射体可以产生第一频段范围内任意频率的谐振频率，第二辐射体可以产生第二频段范围内任意频率的谐振频率；又因为所述第一频段和所述第二频段的组合覆盖3.3GHz至5.0GHz中的所有频率，因此通过第一辐射体和第二辐射体可以实现3.3GHz至5.0GHz的有效辐射，因此本公开实施例提供的天线可以实现3.3GHz至5GHz的有效辐射。

本公开的说明书和权利要求书中的术语“第一”和“第二”等是用于区别同步的对象，而不是用于描述对象的特定顺序。例如，第一接口和第二接口等是用于区别不同的接口，而不是用于描述接口的特定顺序。
在本公开实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的” 或者“例如”等词旨在以具体方式呈现相关概念。此外，在本公开实施例的描述中，除非另有说明，“多个”的含义是指两个或两个以上。
目前，终端设备移动终端通信频段主要是3GHz频率以下频段，终端设备在天线设计时基本没有考虑3.3GHz-5GHz的频率特性，因此目前终端设备的天线无法实现3.3GHz-5GHz的有效辐射。
为了解决该问题，本公开实施例提供一种天线及终端设备，该天线包括：天线馈源、第一辐射体、第二辐射体以及参考地，其中，所述第一辐射体的第一端与所述天线馈源电连接，所述第一辐射体的第二端与所述参考地电连接，所述第二辐射体的第一端浮空，所述第二辐射体的第二端与所述参考地电连接；所述第一辐射体与所述第二辐射体耦合；所述第一辐射体，用于在所述天线馈源输出的馈源信号以及与所述第二辐射体耦合生成的第一耦合信号的作用下产生第一谐振频率；所述第二辐射体，用于在与所述第一辐射体耦合产生的第二耦合信号的作用下产生第二谐振频率；由于第一谐振频率的频率范围为第一频段，第二谐振频率的频率范围为第二频段，因此第一辐射体可以产生第一频段范围内任意频率的谐振频率，第二辐射体可以产生第二频段范围内任意频率的谐振频率；又因为所述第一频段和所述第二频段的组合覆盖3.3GHz至5.0GHz中的所有频率，因此通过第一辐射体和第二辐射体可以实现3.3GHz至5.0GHz的有效辐射，因此本公开实施例提供的天线可以实现3.3GHz至5GHz的有效辐射。
本公开实施例提供的终端设备可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、电子相框、个人数字助理(personal digital assistant，PDA)、智能手表、智能手环等，或者该终端设备还可以为其他类型的终端设备，本公开实施例不作限定。

进一步的，参照图5所示，本公开实施例提供的天线还包括：匹配电路15；
所述匹配电路15串接于所述天线馈源11与所述第一辐射体12之间，用于调节所述第一辐射体12的电阻和/或电抗。

可选的，上述终端设备还包括：第二天线；
所述第二天线，用于产生小于3GHz的谐振频率。
即，本公开实施例在终端设备中独立设置3.3GHz至5.0GHz频段的天线与3GHz以下频段的天线，使3.3GHz至5.0GHz频段的天线与3GHz以下频段的天线在辐射体上不共享，由于本公开实施例提供的终端设备使3.3GHz至5.0GHz频段的天线与3GHz以下频段的天线在辐射体上不共享，因此可以避免使用调谐开关，进而避免调谐开关在高频阶段带来的损耗。
