Description

一种天线及可穿戴电子产品
本申请要求于2019年9月29日提交中国专利局、申请号为201910931290.4、发明名称为“一种天线及可穿戴电子产品”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及天线技术领域，特别是涉及一种天线及可穿戴电子产品。
背景技术
可穿戴电子产品，如智能手表、智能手环等广泛应用在人们的生活中。可穿戴设备通常需要与其它终端设备交互实现相应的功能，因此，可穿戴设备上需要设置多种频段天线。
对于可穿戴设备，通常尺寸较小，很少使用外置天线，普遍采用内置天线，使得产品集成度高。由于可穿戴设备的本身尺寸小，内部的空间也较小，当两个天线设置在其中时，天线间的隔离度就是一个不容忽视的问题。
为了改善天线的隔离度，现有技术中，可以通过更改天线的辐射单元的形状或者改变天线的馈电接地位置。无论是更改天线的辐射单元的形状还是改变天线的馈点接地位置都需要占用足够的空间才能实现，这显然不适合应用在小型化的可穿戴电子产品上，因此，上述两种方式的改善效果并不明显。
发明内容
本发明的目的是提供一种天线，用于提高其中两个天线之间的隔离度，该天线无需更改天线的辐射单元的形状，适用于小型化的可穿戴电子产品。在此基础上，本发明的目的还提供一种包含上述天线的可穿戴电子产品。
为解决上述技术问题，本发明提供一种天线，包括工作频率不同的第一天线和第二天线，还包括设置于所述第一天线的末端和所述第二天线的末端的隔离部，所述隔离部具有蛇形走线。
优选地，所述第一天线为全频段天线，所述第二天线为非全频段天线。
优选地，所述第一天线为2G天线/3G天线/4G天线，所述第二天线为GPS天线/蓝牙天线/WIFI天线。
优选地，所述第一天线的末端和所述第二天线的末端均与所述隔离部直接连接。
优选地，所述第一天线、所述第二天线和所述隔离部一体设置。
优选地，所述第一天线的末端与所述第二天线的末端均与所述隔离部耦合连接。
优选地，所述第一天线的末端与所述隔离部耦合连接，所述第二天线的末端与所述隔离部直接连接。
优选地，所述第一天线的末端与所述隔离部直接连接，所述第二天线的末端与所述隔离部耦合连接。
为解决上述技术问题，本发明还提供一种可穿戴电子产品，包括上述所述的天线。
优选地，电子产品为智能手表或智能手环或智能耳机或智能眼镜。
本发明所提供的天线，包括工作频率不同的第一天线、第二天线以及设置于第一天线的末端和第二天线末端的隔离部，隔离部具有蛇形走线。由于隔离部具有蛇形走线，延长了天线辐射电流的路径，使得第一天线的电流和第二天线的电流在隔离部的作用下，能够较大程度的衰减，进而提高第一天线和第二天线的隔离度。由此可见，采用本实施例提供的技术方案，结构简洁，无需更改天线的辐射单元的形状，并且，对于布局空间紧张的小型化的可穿戴电子产品来说，不需要占用过多的空间即可明显提高两个天线的隔离度。进一步的，本技术方案无需更改天线模具，调试、测试周期较短。最后，添加的隔离部增加了天线辐射主地的面积(或者长度)，因此，提升了天线的效率。
此外，本发明所提供的可穿戴电子产品，包括上述天线，效果同上。
附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面 描述中的附图仅仅是本申请的一部分附图，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。
图1为本发明实施例提供的一种天线的结构图；
图2为本发明实施例提供的一种采用隔离部和未采用隔离部的隔离度效果对比图；
图3为本发明实施例提供的另一种天线的结构图。
具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本发明的核心是提供一种天线，用于提高其中两个天线之间的隔离度，该天线无需更改天线的辐射单元的形状，适用于小型化的可穿戴电子产品。在此基础上，本发明的目的还提供一种包含上述天线的可穿戴电子产品。
为了使本技术领域的人员更好地理解本发明方案，下面结合附图和具体实施方式对本发明作进一步的详细说明。
图1为本发明实施例提供的一种天线的结构图。如图1所示，该天线包括工作频率不同的第一天线10和第二天线11，还包括设置于第一天线10的末端和第二天线11的末端的隔离部12，隔离部12具有蛇形走线。
需要说明的是，本实施例中提到的天线可以包括多个天线，并不代表只有两个天线，这里的第一天线和第二天线仅仅为了区分两个工作频率不同频率的天线。例如，可以有3个天线，A天线、B天线和C天线，那么A天线和B天线可以分别为第一天线和第二天线，或者A天线和C天线分别为第一天线和第二天线，或者B天线和C天线分别为第一天天线和第二天线。
由于工作频率不同，导致第一天线和第二天线会存在相互干扰的问题，本实施例中，通过隔离部将第一天线的末端和第二天线的末端连接，当第一天线的电流经过末端时，电流依然较强，但是再经过隔离部后，电流就会衰减，以此降低对第二天线的影响；同样的，当第二天线的电流经过末端时，电流依然较强，但是再经过隔离部后，电流就会衰减，以此降低对第一天线 的影响。由于隔离部具有蛇形走线，增大了电流流经的路径，所以第一天线的电流在经过蛇形走线后，衰减较大，进一步降低对第二天线的影响；同样的，第二天线的电流在经过蛇形走线后，衰减较大，进一步降低对第一天线的影响。需要说明的是，对于隔离部而言，可以是在第一天线或第二天线其中一个在工作时起到隔离作用，也可以是两个天线都在工作时起到隔离作用。
需要说明的是，本实施例中的隔离部可以与第一天线的末端和第二天线的末端直接连接，也可以是耦合连接。隔离部的两端的形状需要与第一天线的末端和第二天线的末端的形状相配合。在一种具体实施方式中，隔离部为金属铜。可以理解的是，隔离部只要是金属即可，除了金属铜以外，还可以是镍或金等。在具体实施中，可以采用LDS(激光直接成型技术)或FPC(柔性电路板)工艺实现。以隔离部为金属铜为例进行说明，如果是采用LDS工艺，则利用激光镭射技术直接在目标位置上化镀形成隔离部，如果是采用PFC工艺，则采用金属铜作为基材。可以理解的是，上述两种工艺仅仅是一种具体应用场景，根据实际情况选取其中的一种即可。
可以理解的是，本实施例中提到的蛇形走线属于弯折曲线，相比于直线，可以增加第一天线的末端和第二天线的末端的距离。因此，在较为紧张的布局空间上，可以占用较小的距离且能够达到延长电流路径的目的。
另外，本发明对于蛇形走线的具体形状不作限定，可以是锯齿状，当然，可以是规则的锯齿状，也可以是不规则的锯齿状。另外，蛇形走线的线宽、线长、以及开槽深度需要根据隔离度较差的频点要求进行设置，本实施例不再赘述。
本实施例提供的天线，包括工作频率不同的第一天线、第二天线以及设置于第一天线的末端和第二天线末端的隔离部，隔离部具有蛇形走线。由于隔离部具有蛇形走线，延长了辐射电流的路径，使得第一天线的电流和第二天线的电流在经过隔离部时，能够较大程度的衰减，进而提高第一天线和第二天线的隔离度。由此可见，采用本实施例提供的技术方案，结构简洁，无需更改天线的辐射单元的形状，可通过LDS或FPC工艺实现，并且，对于布局空间紧张的小型化的可穿戴电子产品来说，不需要占用过多的空间即可明显提高两个天线的隔离度。进一步的，本技术方案无需更改天线模具，调试、 测试周期较短。最后，添加隔离部增加了天线辐射主地的面积(或者长度)，因此，提升了天线的效率。
图2为本发明实施例提供的一种采用隔离部和未采用隔离部的隔离度效果对比图。如图2所示，实线表示采用隔离部的隔离度，虚线表示未采用隔离部的隔离度。从图2中可以明显确定，采用隔离部使得第一天线和第二天线之间的隔离度有较明显提升。
在上述实施例的基础上，第一天线为全频段天线，第二天线为非全频段天线。可以理解的是，全频段天线的频带范围非常大，能够覆盖多个频率，例如，第一天线为2G天线/3G天线/4G天线。非全频段天线的频带范围较窄，例如，第二天线为GPS天线/蓝牙天线/WIFI天线。当第一天线和第二天线设置在小型化可穿戴电子产品中时，第一天线和第二天线分别实现各自的功能，通过隔离部，降低了第一天线和第二天线的相互干扰，使得小型化可穿戴电子产品的信号质量提高。
在一种具体实施方式中，第一天线的末端和第二天线的末端均与隔离部直接连接，为了提高第一天线、第二天线和隔离部的稳固性，通常是将隔离部与第一天线和第二天线一体设置。当然，除了一体设置，还可以是分体设置，再通过相应的固定方法固定，例如通过弹片连接、或压焊连接、或特定连接器。需要说明的是，相比于分体设置而言，一体设置占用空间小，更适用于小型化产品，例如，可穿戴电子产品。
在上述实施的基础上，本实施例中，第一天线的末端与第二天线的末端均与隔离部耦合连接。
图1中，第一天线的末端和第二天线的末端是通过隔离部直接连接，即第一天线的末端的电流和第二天线的末端的电流直接流到隔离部。本实施例中，第一天线的末端和第二天线的末端分别与所述隔离部耦合连接，即第一天线的末端的电流和第二天线的末端的电流不直接流到隔离部，而是通过电磁耦合的方式在隔离部耦合出电流。耦合连接可以作为在直接连接由于结构空间限制难实现的情况下，一种替代方式，并且在某种天线设计环境下性能 优于直接连接。另外，耦合连接在天线工艺实现上减小天线LDS或者FPC走线过窄时的断线或者裂纹风险。
需要说明的是，除图1中第一天线的末端和第二天线的末端均与隔离部直接连接，以及第一天线的末端和第二天线的末端均与隔离部耦合连接外，还可以是耦合连接和直接连接组合使用，即可以是第一天线的末端与隔离部直接连接，第二天线的末端与隔离部耦合连接、或者是第一天线的末端与隔离部耦合连接，第二天线的末端与隔离部直接连接。图3为本发明实施例提供的另一种天线的结构图。如图3所示，第一天线10的末端与隔离部12耦合连接，第二天线11的末端与隔离部12直接连接。
上文中对于天线的实施例进行了详细说明，本发明还提供一种可穿戴电子产品，该产品包括上述任一实施例所述的天线。此处的，电子产品可以为智能手表或智能手环或智能耳机或智能眼镜。
本实施例提供的可穿戴电子产品，包含有电子产品本体和天线，其中，天线包括工作频率不同的第一天线、第二天线以及设置于第一天线的末端和第二天线末端的隔离部，隔离部具有蛇形走线。由于隔离部具有蛇形走线，延长了电流的路径，使得第一天线的电流和第二天线的电流在隔离部的作用下，能够较大程度的衰减，进而提高第一天线和第二天线的隔离度。由此可见，采用本实施例提供的技术方案，结构简洁，无需更改天线的辐射单元的形状，并且，对于布局空间紧张的小型化的可穿戴电子产品来说，不需要占用过多的空间即可明显提高两个天线的隔离度。进一步的，本技术方案无需更改天线模具，调试、测试周期较短。最后，添加隔离部增加了天线辐射主地的面积(或者长度)，因此，提升了天线的效率。
本说明书中各个实施例采用并列或者递进的方式描述，每个实施例重点说明的都是与其它实施例的不同之处，各个实施例之间相同或相似部分互相参见即可。对于实施例公开的装置而言，由于其与实施例公开的方法相对应，所以描述的比较简单，相关之处可参见方法部分说明。
还需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，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、物品或者设备不仅包括那些要素，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、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
