Description

天线结构及采用该天线结构的终端设备 技术领域
本申请涉及移动通信技术领域，尤其涉及移动设备技术领域，具体涉及一种天线结构及采用该天线结构的终端设备。
 背景技术
通讯技术日新月异的发展，为相关行业带来了新的契机，同时也提出了新的挑战。终端设备（例如手机）由于其便捷的形式和强大的功能，已经成为当代人们不可或缺的电子产品。伴随着电子技术的发展，手机不仅集成了更多的功能，如音乐，视频等娱乐及其他功能，其外形和质感也要随着当代人的审美做出相应的改变。由于其更好的质感、美观及耐用性，全面屏、纯金属及模内注塑金属边框方案已经成为现今手机市场的主流配置。
天线作为无线信号接收和发射的重要器件，其性能的优劣往往决定着一款手机设备的好坏。由于天线本身的物理特性，其辐射能力受制于天线辐射主体周围的其它金属、高介电常数和高损耗的材料。然而，现行市面上的手机朝着更大屏占比的全面屏方向发展，天线空间被一步步压缩。为了在这种环境下获得更好的天线性能，相关研发人员往往选择利用更靠边沿的金属边框作为天线或者天线的一部分。由于金属边框牵涉到外观和制作工艺，其形状尺寸和位置不能随意改动，这样又给天线设计带来了更多的制约。
现行移动通讯技术为2G、3G、4G并存并朝着5G技术方向发展，手机整体空间有限，这样就要求单独一个天线覆盖更多的频段。利用不同天线枝节间的电磁耦合帮助获得更大的频段带宽，已经是业内常用手段。然而，由于上文所述使用金属边框作为天线的限制，在金属边框不同的天线枝节之间往往由于距离太远或重叠面积不够大，导致电磁耦合强度不够，进而影响所设计天线的性能。尤其是在模内注塑金属边框方案中，金属边框需要做到更薄以便在其外面包覆一层塑料，更易造成不同天线枝节间耦合强度弱。为了解决此类问题，比较简单的做法有：减小金属边框之间的开槽宽度，以增近两个天线枝节之间的距离；使用额外的辅助走线，以帮助激发不同金属边框上的电磁耦合。这些虽然也是有效的解决方案，但会受制于工艺，并对成本和可靠性带来影响，其效果也往往不如预期。
有鉴于此，亟需提供一种天线结构及采用该天线结构的终端设备。

具体的，请参阅图1至图4，本申请实施例提供一种天线结构100，适用于一终端设备200。
所述天线结构100包括：一金属边框101。所述金属边框101作为终端设备200（例如移动手机）壳体。进一步而言，终端设备200壳体可以采用纯金属边框或者模内注塑金属边框。
在所述金属边框101的一侧设有一开槽部130。所述开槽部130两侧的金属边框101分别通过一金属接地件140接地后形成第一天线枝节110和第二天线枝节120。所述第二天线枝节120与所述第一天线枝节110相互电磁耦合。其中所述开槽部130包括第一槽口131和第二槽口132，所述第一槽口131和所述第二槽口132之间在沿所述金属边框101的横轴方向上的距离大于零。
具体的，所述第一天线枝节110与所述终端设备200中的第一天线开关151连接。所述第一天线枝节110通过所述第一天线开关151分别与设于所述终端设备200内的多个第一分路161连接。当然，第一天线枝节110可以通过双工器等与第一分路161连接。如图1所示，第一分路161为4个第一分路，用于使得第一天线枝节110所形成的天线可以工作在不同的频段。当然，在其他部分实施例中，第一分路161的数量不限于此。
所述第二天线枝节120与所述终端设备200中的第二天线开关152连接。所述第二天线枝节120通过所述第二天线开关152分别与设于所述终端设备200内的多个第二分路162连接。如图1所示，第二分路162为4个第二分路，用于使得第二天线枝节120所形成的天线可以工作在不同的频段。当然，在其他部分实施例中，第二分路的数量不限于此。
所述第一天线枝节110与所述终端设备200中的第一馈电电路170连接，所述第一馈电电路170可以包括多个RL电路。
所述第一天线枝节110与所述终端设备200中的匹配电路相连，所述匹配电路用于调节天线的阻抗匹配，用以进一步改善天线带宽。
所述第一馈电电路170用于调节所述第一天线枝节和第二天线枝节的辐射频率。
所述第一天线枝节110和所述第二天线枝节120的走线形式为环形（LOOP）天线、倒F(Invert F Antenna,简称IFA)天线、缝隙（SLOT）天线、单极子(monopole)天线等形式中的任意一种。通过调节第一馈电电路170的位置以及第一馈电电路170与第一天线枝节110的连接关系，可以使得天线以不同形式出现。例如，将第一馈电电路170与第一天线枝节110的连接点设置在靠近金属接地件140的位置，则第一天线枝节110的天线形式为IFA天线。将第一馈电电路170与第一天线枝节110的连接点设置于靠近缝隙部的位置，使得第一天线枝节110的天线形式为LOOP天线或SLOT天线。
同样，通过调节第一馈电电路170的位置以及第一馈电电路170与第二天线枝节120的连接关系，可以使得天线以不同形式出现。例如，将第一馈电电路170与第二天线枝节120的连接点设置在靠近金属接地件140的位置，则第二天线枝节120的天线形式为IFA天线。将第一馈电电路170与第二天线枝节120的连接点设置于靠近缝隙部的位置，使得第二天线枝节120的天线形式为LOOP天线或SLOT天线。
在本实施例中，所述第一天线枝节110用于产生第一谐振和第二谐振，其中第二谐振的频率大于第一预设频率（或称为高频），所述第一谐振的频率小于第二预设频率（或称为低频）。所述第二天线枝节120用于产生第三谐振，所述第三谐振的频率大于所述第二谐振的频率。具体的，例如第一预设频率为1700MHz,第二预设频率为900MHz。第一天线枝节110产生的第二谐振为1800MHz,为中高频，第一天线枝节110产生的第一谐振为850MHz。第二天线枝节120产生第三谐振，其频率为2200Mhz。也就是说，第一天线枝节110产生低频和中高频，第二天线枝节120受到第一天线枝节110的电磁耦合激励而产生更高频的谐振。
另外，所述第一天线开关151用于控制产生所述第一谐振和第二谐振的频段，第二天线开关152用于控制产生所述第三谐振的频段。
由于耦合馈电（或称寄生），第二天线枝节120上所产生的高频谐振强度甚至能否产生谐振，其受到与第一天线枝节110之间的开槽部130的形状尺寸的影响。相对于常规开槽，本申请提供“Z”字型开口槽，能够在不改变开槽部130的宽度（受限于制作工艺，一般不低于1mm）的情况下，通过增加第二天线枝节120和第一天线枝节110之间的耦合强度，进而避免因耦合强度不够所导致的整体天线性能不足的问题。
具体地，在本实施例中，在所述终端设备200的底部，即金属边框101的一侧（底部一侧）设有一开槽部130。所述开槽部130在沿金属边框101的纵轴方向上投影呈Z字型，如图2、图3和图4所示。具体的，所述开槽部130包括第一开槽部和第二开槽部。所述第一开槽部大体上呈L型或近似凸型（其中部分开槽部作为终端设备200的出音孔），第二开槽部大体上呈L型。所述第一开槽部具有所述第一槽口131，所述第二开槽部具有所述第二槽口132，所述第一开槽部和第二开槽部彼此连通。
由于所述第一槽口131和所述第二槽口132之间在沿所述金属边框101的横轴方向上的距离大于零，因此，相较于常规开槽部180呈“1”字型开槽，如图5所示，本申请所述开口槽呈“Z”字型开槽，如图4所示，即所述开槽部130相对于金属边框101的正对面积得到提高，这样能够改善第一天线和第二天线之间的电磁耦合强度，从而获得更好的天线性能。当然，本申请所述开槽部130的形状不仅限于“Z”字型开槽部，只要其能够改变开槽位置相对于金属边框101的正对面积也亦在本申请的保护范围之内。这样，通过改变金属边框101一侧的开槽部130的形状，以改变开槽部130的开槽位置相对于金属边框101的正对面积，进一步改善不同天线枝节（此处为第一天线枝节110和第二天线枝节120）之间的电磁耦合强度，从而保证设计天线的性能。
在本实施例中，所述第一槽口131的宽度和所述第二槽口132的宽度均位于1mm至2mm之间，优选地，所述第一槽口131的宽度和所述第二槽口132的宽度均为1.5mm。
参阅图6，其为天线结构100中的开槽部呈“1”字型开槽和“Z”字型开槽的天线效率与频率关系示意图。
该图为通过一测试项目中分别采用常规开槽方式和采用Z字型开槽所获得的不同效率结果的示例。
在该测试环境中，还具体包括：模内注塑金属方案手机天线，天线净空约1.5mm，采用金属边框101作为天线并不使用其他天线走线。
当采用常规开槽方式时，由于塑料内部金属边框尺寸较薄，且开槽部的宽度受制于制作工艺，尺寸不能再缩小。如图5所示的开槽部180设计，第一天线枝节110和第二天线枝节120之间的电磁耦合强度不够，第一天线枝节110和第二天线枝节120所产生的高频（例如1700 MHz 至2200MHz）谐振难以获得良好的阻抗匹配，进而导致高频效率低下，难以符合设计需求。
当采用“Z”字型开槽方式，其他参数均和采用常规开槽方式保持一致。根据图6所示，从图中可以看出“Z”字型开槽方式所取得的高频天线效率明显高于常规开槽方式。虽然并未改变开槽宽度，但是由于“Z”字型开槽方式增大了第一天线枝节110和第二天线枝节120之间的开槽部130相对于金属边框101的正对面积，改善了第一天线枝节110和第二天线枝节120之间的电磁耦合强度，以获得更好的天线增益和带宽，从而获得了更好的高频天线性能。
参阅图7，本申请提供一种终端设备200，所述终端设备200包括上述天线结构，所述天线结构中的金属边框101为所述终端设备200的壳体。终端设备200壳体可以采用纯金属边框或者模内注塑金属边框。进一步，终端设备200还可以包括处理器201、存储器202。其中，处理器201与存储器202连接。所述终端设备200可以为手机、平板以及电脑等设备。

终端设备300还包括给各个部件供电的电源390（比如电池），在一些实施例中，电源可以通过电源管理系统与处理器380逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。电源390还可以包括一个或一个以上的直流或交流电源、再充电系统、电源故障检测电路、电源转换器或者逆变器、电源状态指示器等任意组件。
尽管未示出，终端设备300还可以包括摄像头（如前置摄像头、后置摄像头）、蓝牙模块等，在此不再赘述。具体在本实施例中，终端设备的显示单元是触摸屏显示器，终端设备还包括有存储器，以及一个或者一个以上的程序，其中一个或者一个以上程序存储于存储器中，且经配置以由一个或者一个以上处理器执行一个或者一个以上程序。
具体实施时，以上各个模块可以作为独立的实体来实现，也可以进行任意组合，作为同一或若干个实体来实现，以上各个模块的具体实施可参见前面的实施例，在此不再赘述。
以上对本申请实施例所提供的一种天线结构及采用该天线结构的终端设备进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
