Description

天线单体、天线阵列及电子设备 技术领域
本申请涉及通信技术领域，尤其涉及一种天线单体、天线阵列及电子设备。
 背景技术
随着需求的不断增长，现有移动通信系统难以满足未来需求，5G技术以逐步普及开来，相较于4G技术，5G技术具有更高的数据传输速率、更低的延迟等优点，但5G技术仍受制于天线技术。
 技术问题
在传统5G天线设计中，通常需要通过增加耦合片的尺寸以保证信号质量，但是耦合片的尺寸增加便会导致隔离度的下降，而为了保证隔离度便需要增加天线的整体尺寸，这样便会导致天线的体积增加，应用于电子设备中时便会影响其轻便化设计。因此，有必要设计一种新型的天线，以改变现状。
 技术解决方案
有鉴于此，本申请提供了一种天线单体、天线阵列及电子设备，用于提高天线的性能。

 本发明的实施方式
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清楚、完整地描述，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作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。
本申请实施例提供了一种天线单体100，参阅图1和图5所示，该天线单体100包括基层结构110以及贴片组件120，基层结构110包括依次层叠设置的第一承载层111、介质层112和第二承载层113，并用于承载贴片组件120；请继续参阅图2和图3，贴片组件120包括平行且间隔设置的反射板121、馈电贴片122和耦合片123，并固定于基层结构110上；反射板121设于第一承载层111远离第二承载层113的一侧，耦合片123设于第二承载层113远离第一承载层111的一侧，馈电贴片122设于第一承载层111和第二承载层113之间；耦合片123与馈电贴片122在反射板121上的投影至少部分互不重合。
在本实施例的天线单体100中，反射板121、馈电贴片122和耦合片123平行且间隔设置，且耦合片123与馈电贴片122在反射板121上的投影至少部分互不重合。本实施例的天线单体100与现有的天线相比，无需增加耦合片123的尺寸，避免了隔离度的下降，以使天线单体100具有紧凑的结构，便于安装布置。
参阅图2和图3所示，在一实施例中，反射板121开设有通孔1211，馈电贴片122还包括竖直设于馈电贴片122远离耦合片123一侧的探针124，且馈电贴片122贴附于第一承载层111，探针124穿设于第一承载层111并与反射板121分离，且探针124在反射板121上的投影位于通孔1211内。
通过在反射板121上开设的通孔1211，当探针124实现信号连接时，通孔1211可以避让探针124，探针124便与反射板121互不连接。参阅图2、图3和图5所示，在本实施例中通孔1211的截面为圆形，在其他实施例中，通孔1211也可以根据实际情况设置为对应的结构。
进一步地，馈电贴片122包括贴片本体1221以及自贴片本体1221的边缘向外延伸的连接凸部1222，探针124的一端连接于连接凸部1222，且探针124在连接凸部1222上的正投影位于连接凸部1222内。
可以理解地是，通过形成于贴片本体1221边缘的连接凸部1222，并且探针124在连接凸部1222上的投影面积小于连接凸部1222的面积，在装配本实施例的馈电贴片122时，连接凸部1222可以提供足够的与探针124接触的面积，从而便于馈电贴片122的装配。
参阅图4所示，耦合片123具有相对的第一边1231和第二边1232，第一边1231朝向第二边1232的第一方向，馈电贴片122具有相对的第一侧边1223和第二侧边1224，第一侧边1223朝向第二侧边1224的方向为第二方向，第一方向与第二方向在反射板121上的投影之间具有夹角。
定义图4中D1方向为第一边1231至第二边1232的方向，定义D2方向为第一侧边1223至第二侧边1224的方向，定义图中角度α为D1方向和D2方向，通过设置D1方向与D2方向之间的夹角，由此使馈电贴片122和耦合片123在反射板121上的正投影之间具有互相不重合的部分，也就是馈电贴片122的至少部分投影与耦合片123不重合，耦合片123也有至少部分投影与馈电贴片122不重合。
参阅图4所示，在一实施例中，第一边1231平行于第二边1232，第一侧边1223平行于第二侧边1224，第一方向与第二方向之间的夹角为45°。
具体在本实施例中，馈电贴片122和耦合片123均大致为矩形，D1和D2之间的夹角为45°，且馈电贴片122和耦合片123的几何中心在反射板121上投影互相重合；馈电贴片122和耦合片123在反射板121上的投影中，馈电贴片122的四个顶角自耦合片123的四边凸出，耦合片123的四个顶角自馈电贴片122的四边凸出。
在其他实施例中，馈电贴片122和耦合片123的几何中心在反射板121上投影也可以互不相交，在满足耦合片123与馈电贴片122在反射板121上的投影至少部分互不重合的前提下，D1和D2也可以根据实际情况设置对应的夹角数值，在此不做唯一限定。
参阅图3和图5所示，在一实施例中，介质层112朝向第一承载层111的一侧开设有容纳槽1121，且馈电贴片122容置于容纳槽1121内。
通过在介质层112上开设有容纳槽1121，在天线单体100装配完成之后，馈电贴片122可以容置于容纳槽1121内，从而使介质层112与第一承载层111紧密贴附，即可以缩减天线单体100的整体厚度，以使天线单体100具有更为紧凑的结构，同时馈电贴片122也可以通过容纳槽1121进行定位。
在本实施例中，介质层112的数目为两层，且两层介质层112层叠设置，容纳槽1121设于靠近第一承载层111的介质层112上。在其他实施例中，介质层112也可以根据实际需求设置对应的层数，介质层112的层数可以是一层、三层或三层以上。
具体在一些实施例中，介质层112为聚丙烯层。第一承载层111和第二承载层113为PCB板，由此设置，可以便于反射板121、馈电贴片122和耦合片123的固定布置，同时PCB加工工艺成熟，在保证天线单体100的生产一致性的前提下，也可以达到优化天线单体100的制造成本的效果。
参阅图6所示，本申请实施例还提供了一种天线阵列10，其包括上述任意一实施例中的天线单体100，其中，天线阵列10包括多组均连接于基层结构110的贴片组件120，且多组贴片组件120沿直线方向均匀且间隔排布。
在本实施例的天线阵列10中，通过在基层结构110上设置多个贴片组件120，以使本天线阵列10在具有良好性能的前提下同时具有紧凑的结构，便于布置和应用。
参阅图6所示，在一实施例中多个贴片组件120沿X方向均匀且间隔设置，具体地，每两个相邻的贴片组件120之间的间隔尺寸L为5.8mm。在其他实施例中，贴片组件120之间的间隔尺寸也可以根据实际设计需求进行设定，在此不做唯一限定。
参阅图6所示的实施例，贴片组件120的数目为四组。需要说明的是，在本实施例中，天线阵列10在X方向上的尺寸为23.4mm，天线阵列10在Y方向上的尺寸为6mm，天线阵列10在Z方向上的尺寸为1.54mm；天线阵列10具有紧凑的结构，整体体积较小，便于安装与布置。
参阅图7所示，本申请实施例还提供了一种电子设备1，其包括壳体20以及上述任意一实施例中的天线阵列10，天线阵列10固定于壳体20上。
通过设置上述实施例中的天线阵列10，由于天线阵列10的体积较小，在电子设备1的壳体20布置时占用的空间较小，便于电子设备1的轻薄化设计，同时对电子设备1中例如2G、3G、4G天线的影响较小，使用效果好。
需要说明的是，上述实施例中的天线阵列10能够工作在24.25GHz-27.5GHz的范围内；通过上述设置，可以使天线阵列10的增益达到11.8dBi，并且具有89°的水平波瓣宽度；进一步通过应用波束赋形（Beamforming）技术，可以使天线阵列10的垂直扫描角度达到103°，天线阵列10具有良好的性能。
进一步地，电子设备1包括有多组天线阵列10，且多组天线阵列10分别固定于壳体20上。
可以理解地是，通过在电子设备1的壳体20上设置多组天线阵列10，在多组天线阵列10相互配合的作用下，可以保证电子设备1的信号覆盖效果。
参阅图7所示的实施例，天线阵列10的数目为三组。在本实施例中，壳体20具有第一侧壁21以及与第一侧壁21相邻的第二侧壁22和第三侧壁23，第二侧壁22与第三侧壁23相对设置；其中一组天线阵列10固定于第一侧壁21上，另外两组天线阵列10分别固定于第二侧壁22上和第三侧壁23上。
参阅图7所示的摆放状态，本实施例的电子设备1通过在壳体20的三个侧壁上各设置有一个天线阵列10，当竖持电子设备1时，位于第一侧壁21上的天线阵列10便不会受到遮挡，同时第二侧壁22和第三侧壁23上的至少一个天线阵列10也不会受到遮挡，从而可以保证电子设备1的信号覆盖；当横持电子设备1时，例如将第一侧壁21朝向左侧，第二侧壁22朝向上侧，此时至少第二侧壁22和第三侧壁23上的天线阵列10不会受到遮挡，从而保证电子设备1的信号覆盖。
可以理解地是，通过上述的天线阵列10布置，可以保证电子设备1在使用过程中的信号覆盖。在其他实施例中，天线阵列10的数目也可以设置为两组、四组或四组以上，在此不做唯一限定。
以上所揭露的仅为本申请较佳实施例而已，当然不能以此来限定本申请之权利范围，因此依本申请权利要求所作的等同变化，仍属本申请所涵盖的范围。
