Description

天线组件、具有此天线组件的无线通信电子设备及遥控器
本申请要求于2017年5月12日提交中国专利局、申请号为201710335550.2、申请名称为“天线组件及具有此天线组件的无线通信电子设备”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】
本申请涉及通信领域，特别涉及一种天线组件、具有此天线组件的无线通信电子设备及遥控器。
【背景技术】
天线作为发射或接收无线电波的电子器件，是通信行业不可或缺的一种元件，为了适应无线通信电子设备小型化的需求，天线不断向着小型化方向发展。目前市面上使用的微带天线，具有小型化、易集成、方向性好等优点，因而被广泛应用于通信行业。
微带天线通常设置在一个薄介质基片上，一面附上金属薄层作为接地板，另一面帖上一定形状的金属贴片作为辐射元件，同时利用微带线或同轴探针对贴片馈电，从而构成一个完整的微带天线。目前，微带天线都是作为一个完整的元件安装于无线通信电子设备，其一部分设置于无线通信电子设备内部，另一部分外露。然而，这样的结构并不能完全满足无线通信电子设备小型化的需求。另外，现有的微带天线生产商多选用罗杰斯(Rogers)板材作为微带天线的介质板材，成本较高。例如，包括两个辐射元件、整体尺寸在50×100mm左右的微带天线的售价通常在五十元上下，因而增加了无线通信电子设备的总成本。

除非另有定义，本说明书所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。在本申请的说明书中所使用的术语只是为了描述具体的实施方式的目的，不是用于限制本申请。本说明书所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
请参阅图1和图2，为本申请其中一实施例提供的一种天线组件100，其安装于无线通信电子设备内部。该无线通信电子设备包括基板200和具有屏幕300的显示装置，上述屏幕300背面设置有金属件302。该金属件302在该无线通信电子设备用作对屏幕300进行屏蔽的屏蔽板，以防止显示装置的屏幕300受到无线通信电子设备中的其他电子元器件的干扰。该无线通信电子设备可为手机，平板或其他带有显示装置的无线通信电子设备，例如带有显示装置的无人机遥控器。
上述基板200为绝缘介质，可为塑料板，如聚碳酸酯(Polycarbonate，PC)板，基板200的厚度为3.15mm。上述基板200包括第一表面202，第二表面204和端面206(见图2)。端面206连接于第一表面202和第二表面204之间，第一表面202和第二表面204设置于基板200的相对两侧。在本实施例中，上述基板200设置于上述无线通信电子设备内部，用于固定或加固上述显示装置，特别是当屏幕300越大时，刚度越小，通常需要设置基板200对显示装置进行固定。
可以理解的是，在一些其他实施例中，上述基板200可以是无线通信电子设备内部的其他任何绝缘性部件，例如，可以为该无线通信电子设备中用 于容纳屏幕300的前壳、后壳等。
上述天线组件100为微带天线，包括辐射元件20，馈线30，同轴线40。辐射元件20作为整个天线组件100的辐射部分，用于接收和发射信号。在本申请实施例中，馈线30为和同轴线40阻抗匹配的馈电微带线，馈线30起到了用于阻抗匹配的匹配电路的作用。辐射元件20和馈线30设置于基板200的第一表面202，馈线30的一端与辐射元件20电性连接，另一端与同轴线40连接，从而通过同轴线40使天线组件100接地，并且馈线30通过同轴线40连接外围电路，具体将在下文进行说明。
金属件302设置于基板200的第二表面204，作为上述天线组件100的参考地。由于该金属件302是原本就设置在该无线通信电子设备中的用作屏蔽板的部件，在本申请实施例中，又利用该金属件302来作为天线组件100的参考地，因而不必再另外为天线组件100设置单独的参考地，既节约了成本，又节省了空间。
在本实施例中，上述辐射元件20的数量为一个，为矩形金属片，可通过光刻腐蚀方法形成于上述基板200的第一表面202；或者，先将上述辐射元件20制成金属片后，再固定于上述基板200的第一表面202。辐射元件20的尺寸决定了天线组件100的工作频率，可以理解的是，在一些其他实施例中，辐射元件20可根据不同的需求，相应变化尺寸。同样地，辐射元件20的形状不限于为矩形，也可采用其他的形状，如圆形，椭圆形、环形、六边形等。
在本实施例中，上述馈线30为矩形金属片，馈线30可通过光刻腐蚀方法形成于上述基板200的第一表面202；或者，先将上述辐射元件20制成金属片后再固定于上述基板200的第一表面202。可以理解的是，在一些其他实施例中，上述馈线30不限于为金属片，也不限于设置于第一表面202，可根据不同的馈电方式而相应变化。
如上所述，馈线30的一端与同轴线40连接，从而通过同轴线40使天线组件100接地。具体地，同轴线40的一端剥去透明薄膜绝缘层406、编织层和外被，获得裸露的内芯402和裸露的外芯404，内芯402和外芯404之间设置透明薄膜绝缘层406。上述裸露的内芯402焊接于馈线30远离辐射元件20的一端，从而与辐射元件20电性连接，同时可与馈线30实现50欧姆的阻抗匹配；裸露的外芯404连接于作为参考地的金属件302。上述天线组件100还 包括金属连接件，该金属连接件用于将同轴线40的接地端，即，同轴线40的裸露的外芯404与参考地电性连接。从而，完成了对整个天线组件100的馈电。
在本实施例中，上述金属连接件为柔性电路板50。柔性电路板50的一端与同轴线40的接地端即外芯404连接，另一端连接作为参考地的金属件302，从而将同轴线40的接地端与参考地相连。同轴线40的内芯402通过馈线30连接于辐射元件20，同轴线40的外芯404焊接于柔性电路板50，从而通过柔性电路板50将整个天线组件100连接至参考地。另外，馈线30通过同轴线40的内芯402连接外围电路，裸露的外芯404焊接于柔性电路板50。而柔性电路板50通过同轴线40的外芯404连接外围电路。外围电路例如为PCB板上的射频电路，在通电之后工作，射频电路端把信号通过同轴线发送到天线组件100的辐射元件20上，辐射元件20再把这些信号辐射到空气中发射出去。
上述柔性电路板50呈弯折状，靠近基板200的端面206。选择弯折状的柔性电路板50，是为了用该柔性电路板50将设置于基板200的第一表面202的辐射元件20与设置于基板200的第二表面204的金属件302相连接，即，用该柔性电路板50来将天线组件100接地。具体地，柔性电路板50包括第一连接端502和第二连接端504。第一连接端502设置于第一表面202，第一连接端502与上述馈线30相隔预设的距离，上述同轴线40的裸露的外芯404焊接于第一连接端502。第二连接端504设置于第二表面204，并与上述金属件302电性连接。在其他一些实施例中，柔性电路板50可省略，而通过其他金属连接件，例如金属导线将整个天线组件100接地。或者，可采用其他的连接方式使天线组件100接地，例如，可以用同轴线40直接将天线组件100接地，或者直接把天线组件100的辐射元件20的接地端延长，贴合接地。另外，馈线30可通过其他金属连接件，例如金属导线，或者采用其他的连接方式电性连接外围电路；同样地，金属件302也可通过其他金属连接件，例如金属导线，或者采用其他的连接方式电性连接外围电路。
在本申请实施例中，设置于上述屏幕300背面的金属件302为金属板，为用于对屏幕300进行屏蔽的屏蔽板，为防止显示装置的屏幕受到无线通信电子设备中的其他电子元器件的干扰，通常都会设置这样的屏蔽板用于对屏 幕进行屏蔽保护。在本实施例中，是利用了无线通信电子设备的显示装置上本来就具有的屏蔽板作为上述天线组件100的参考地，从而节省了天线组件100的空间。可以理解的是，在本申请的其他一些实施例中，可以不用起到屏蔽作用的该金属件302作为天线组件100的参考地，而是采用无线通信电子设备内部的任何其他金属材质的器件作为上述天线组件100的参考地。例如，若该无线通信电子设备的显示屏的外框架为金属材质，可以利用该金属材质的外框作为上述天线组件100的参考地。
请参阅图3至图6，为本申请另一实施例提供的天线组件400，该实施例中的天线组件400与上述实施例提供的天线组件100基本相同，区别点在于：本实施例提供的天线组件400包括两个辐射元件20，两个辐射元件20通过馈线30a与同轴线40电性连接。
每个辐射元件20为矩形的金属片，两个辐射元件20相隔预设的距离，并对称地设置于对称轴10的两侧。在本实施例中，每个辐射元件20的尺寸为48mm×43mm，在一些其他实施例中，辐射元件20可以具有不同的尺寸。每个辐射元件20包括两个相互平行的第一侧边22和两个相互平行的第二侧边24，第一侧边22垂直于第二侧边24。每个辐射元件20的第一侧边22平行于另一辐射元件20的第一侧边22，类似地，每个辐射元件20的第二侧边24平行于另一辐射元件的第二侧边24。
上述馈线30a包括微带馈线32a和功分微带线34a。上述功分微带线34a的数量为两个，每个功分微带线34a的输入端连接微带馈线32a，每个功分微带线34a的输出端分别连接一个辐射元件20。在本实施例中，上述两个功分微带线34a为等功分微带线，也即两个功分微带线34a的形状相同，尺寸相等。每个功分微带线34a为“L”形，其一端连接一个第二侧边24的中部，另一端连接微带馈线32a的一端。上述两个等功分微带线34a对称地设置于对称轴10的两侧。在本实施例中，两个等功分微带线34a对两个辐射元件20的输入功率进行等分，因此，两个辐射元件20的输入功率相等。在其他一些实施例中，每个功分微带线34a可呈直线，其一端连接一个第二侧边24的中部，另一端连接微带馈线32a的一端，两个呈直线的功分微带线34a对称地设置于对称轴10的两侧。应理解的是，在一些其他实施例中，所述两个功分微带线34a 的长度可以不相等，并且/或者每个所述辐射元件20从所述馈线30a获得的输入功率可以不相等。
上述微带馈线32a沿对称轴10设置，并且其一端连接上述两个功分微带线34a。上述功分微带线34a和微带馈线32a为金属片，与上述辐射元件20一起设置于上述基板200的第一表面202。上述辐射元件20，功分微带线34a以及微带馈线32a的厚度为0.035mm，可通过光刻腐蚀方法形成于上述基板200的第一表面202；或者上述辐射元件20，先将功分微带线34a以及微带馈线32a制成金属片后，再固定于上述基板200的第一表面202。可以理解的是，在一些其他实施例中，上述馈线30a不限于为金属片，也不限于设置于第一表面202，可根据不同的馈电方式而相应变化。
每个辐射元件20的尺寸决定了天线组件400的工作频率；两个辐射元件20的间距决定了天线组件400的增益；功分微带线34a和微带馈线32a的尺寸基本上决定了天线组件400的阻抗匹配。在本实施例中，每个辐射元件20为矩形，尺寸为48mm×43mm。每个辐射元件20远离对称轴10的第一侧边22与另一辐射元件20远离对称轴10的第一侧边22的距离L1为100mm，而每个辐射元件20远离微带馈线32a的第二侧边24与基板200的端面206的距离L2为80mm。功分微带线34a和微带馈线32a实现50欧姆的阻抗匹配。
请参阅图7，本实施例的天线组件400可工作在2.38GHz～2.51GHz，带宽为130MHz，满足常用的2.45GHz频段的覆盖。
请参阅图8和图9，其中图8为图3至图6所示的本实施例的天线组件400在2.45GHz的辐射的E平面方向图，图9为图3至图6所示的本实施例的天线组件400在2.45GHz的辐射的H平面方向图。本实施例的天线组件400为方向性天线，增益可达9dBi。
以下以遥控器为例，对本申请实施例的无线通信电子设备的技术特征进行说明。
请参阅图10，本申请实施例提供一种遥控器600，其用来控制可移动物体。该遥控器600包括遥控主机610和显示器620，所述显示器620的一端可枢转地连接所述遥控主机610。所述遥控器600在使用时，所述显示器620由闭合状态枢转至打开状态。
所述显示器620包括屏幕、固定该屏幕的基板和安装于该基板的天线组 件。
优选地，该显示器620中的天线组件为上述实施例中的天线组件100，400。
优选地，上述的可移动物体为无人飞行器(Unmanned Aerial Vehicle，UAV)。
应理解的是，本申请实施例的无线通信电子设备不限于为遥控器，还可以为手机、平板或其他带有显示装置的无线通信电子设备。
本领域所属技术人员应明白，为了获得不同性能、用途的天线组件400，可以改变辐射元件20的尺寸、形状、数量以及两个辐射元件20之间的间距等，还可以改变功分微带线34a和微带馈线32a的尺寸及相对位置。辐射元件20和功分微带线34a不限于对称地设置于对称轴10的两侧，微带馈线32a不限于沿对称轴10设置，辐射元件20，功分微带线34a和微带馈线32a可根据实际需求改变相对位置关系。
例如，本实施例中的辐射元件20为矩形，在其他一些实施例中可以采取正方形，圆形，椭圆形，环形、六边形等其他形状；其次，本实施例中的辐射元件20的数量为2个，而在其他实施例中可以采用4个辐射元件20，6个辐射元件20等多个辐射元件来形成天线阵。
本申请实施例的天线组件100，400利用无线通信电子设备的基板200作为介质承载辐射元件20，取代了现有技术中用作天线组件的介质的塑料材质(例如背景技术中介绍的罗杰斯板材)，使得天线组件100，400所占用的空间减小。与现有技术中同样尺寸的天线组件相比较，省略罗杰斯板材，利用无线通信电子设备中本来就具有的用于固定或加固显示装置的部件作为天线组件100，400的介质，使得本申请实施例中的天线组件100，400仅剩下辐射元件和馈线的一张很薄的贴片，售价仅在十元出头，节省了天线组件100，400的成本。基板200较厚，也使得天线组件100，400的带宽增大。
而且，本申请实施例的天线组件100，400利用显示装置的屏幕300的背面金属件302作为天线组件100，400的参考地，节省了天线组件100，400的空间，且由于作为参考地的金属件302较大，使得天线组件100，400的性能稳定，方向性较强，实现了天线组件100，400的高增益。
另外，本实施例的天线组件100，400完全内置于上述无线通信电子设备 内部，如应用于遥控器，可满足该无线通信电子设备的小型化需求。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；在本申请的思路下，以上实施例或者不同实施例中的技术特征之间也可以进行组合，步骤可以以任意顺序实现，并存在如上所述的本申请的不同方面的许多其它变化，为了简明，它们没有在细节中提供；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
