技术领域
本发明涉及通信技术领域，尤其涉及移动通信天线设备及移动通信终端设 备。
[0 背景技术
随着无线通信技术的发展， 终端设备的无线性能显得尤为重要。 同时， 终 端设备小型化的趋势， 又使得用于发射与接收无线信号的设备 天线， 越来越 迫切地需要从传统的外置形式改变为内置形式。 然而，从已有的内置天线形式 来看， 由于受到环境的制约， 天线的带宽、 增益、 水平面方向图的不圓度都比 ί5 外置天线要差很多， 导致了用户使用满意度的下降。 因此， 如何提高内置天线 设备的相关性能指标就变得特别迫切。
现有技术中， 大部分内置天线采用在 PCB ( Printed Circuit Board, 印刷电 路板） 的边缘印刷天线的形式， 即在 PCB边缘预留出一部分区域， 在该区域 内不放置元器件， 也没有任何的走线与地， 而是将天线印刷在该区域， 从而实
»0 现无线通信。 也可以采用分离的印刷天线， 与 PCB电气连接， 实现无线通信。
然而， 由于印刷天线与 PCB在同一水平面上， 因此天线的垂直极化分量会艮 少，而水平极化分量会较多，对于农村无线电信号以垂直极化为主的情况来说， 天线的带宽、 增益、 水平面方向图的不圓度均不理想， 用户体验效果较差。
为此， 现有技术提出一种内置天线， 采用在 PCB的边缘放置单极子天线 »5 或 PIFA ( Planar Inverted-F Antenna, 皮法天线）， 同时加无源寄生单元的方式 实现。即在单极子天线或 PIFA天线的馈点旁边增加一个与地导通的亮铜区域， 用一根接近所需频段波长四分之一左右长度的金属片或 FPC ( Flexible Printed Circuit, 柔性电路板），通过弹片连接到该亮铜区域。通过使接地金属片或 FPC 耦合谐振的方式， 来展宽带宽， 从而实现天线工作在常规的 GSM850 ( GSM: Global System for Mobile communications ,全球移动通信系统）、 GSM900, DCS ( Distributed Control System,分布式控制系统 )、 PCS( Personal Communications Service， 个人通讯月良务 ）、 UMTS2100 ( UMTS： Universal Mobile 5 Telecommunication System, 通用移动通信系统）等几个频段。
发明人在实现本发明的过程中， 发现上述现有技术存在如下不足： 天线的带宽只能够勉强满足指标要求， 天线的增益很难提高， 水平面方向 图的不圓度也很难改善， 用户体验效果仍然较差。 ίθ 发明内容
本发明实施例提供一种移动通信天线设备， 用以增加天线带宽，提高天线 增益， 改善天线水平面方向图的不圓度， 该设备包括：
单极子天线，放置于印刷电路板的一侧， 与所述印刷电路板中心位置的距 离小于阔值， 所述单极子天线包括：

本发明实施例还提供一种移动通信终端设备， 用以增加天线带宽，提高天 线增益，改善天线水平面方向图的不圓度，该设备包括上述移动通信天线设备。

»5 线， 所以其增益大、 水平面方向图的不圓度好， 并且， 可以使天线带宽更宽， 可以覆盖 GPS、 Bluetooth频段， 而无需增加新的 GPS、 Bluetooth天线， 节约了 成本。 附图说明
10 为了更清楚地说明本发明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 中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲， 在不付 出创造性劳动性的前提下， 还可以根据这些附图获得其他的附图。 在附图中： 图 1为本发明实施例中移动通信天线设备的结构示意图；
5 图 2为本发明实施例中移动通信天线设备的另一结构示意图；
图 3为本发明实施例中移动通信天线设备仿真得到的天线回波损耗结果示 意图。 具体实施方式
0 为使本发明实施例的目的、技术方案和优点更加清楚明白， 下面结合附图 对本发明实施例做进一步详细说明。在此， 本发明的示意性实施例及其说明用 于解释本发明， 但并不作为对本发明的限定。
本发明实施例提供了一种新的内置天线形式，使得天线工作频段覆盖目前移动 通信终端设备常用的 GSM850、 GSM900, DCS, PCS, UMTS2100, 以及 GPS、 5 Bluetooth等频段。 同时， 天线的增益能够达到常规的外置天线水平。 尤其是 天线的水平面方向图的不圓度与现有的内置天线形式相比， 有了较大改善。
如图 1所示， 本发明实施例中的移动通信天线设备可以包括：
单极子天线 101， 放置于印刷电路板 102的一侧， 与印刷电路板 102中心位置 的距离小于阔值， 该单极子天线 101包括：
Ό 第一金属片 101a，与印刷电路板 102垂直，并通过馈点 101b与印刷电路板 102 的电路相导通。
由图 1所示移动通信天线设备的结构可以得知， 本发明实施例中， 单极子 天线 101放置于印刷电路板 102的一侧，与印刷电路板 102中心位置的距离小 于阔值， 该单极子天线 101包括： 第一金属片 101a， 与印刷电路板 102垂直，
•5 并通过馈点 101b与印刷电路板 102的电路相导通， 实现了以印刷电路板为镜 面的天线镜像， 此时， 印刷电路板的另一侧有一个镜像的单极子天线， 与已有 的单极子天线一起，组成一个偶极子天线， 由于偶极子天线受到印刷电路板的 影响远小于现有技术中放置于印刷电路板边缘的单极子单线或 PIFA天线， 所 以其增益大、 水平面方向图的不圓度好， 并且， 可以使天线带宽更宽， 可以覆
10 盖 GPS、 Bluetooth频段， 实现主天线与 GPS、 Bluetooth天线等的共用， 而无 需增加新的 GPS、 Bluetooth天线， 节约了成本。
具体实施时，单极子天线 101与印刷电路板 102中心位置的距离小于阔值， 可以是： 单极子天线 101大致在印刷电路板 102的中部位置附近， 即距离印刷 电路板 102两条长边的距离大致相同，距离印刷电路板 102两条宽边的距离也 大致相同。 这样， 可以利用印刷电路板的镜像效应， 增加天线带宽， 提高天线 增益， 改善天线水平面方向图的不圓度。
具体实施时， 图 1中的印刷电路板也可以与其它各种形状、功用的金属物 进行组合， 形成金属板 103。 单极子天线 101放置在金属板 103的一侧， 与金 属板 103中心位置的距离小于阔值。 第一金属片 101a是单板子天线 101的主 体部分， 与金属板 103垂直， 并通过馈点 101b与金属板 103的电路相导通， 从而馈电进行无线信号收发工作。
一个实施例中， 如图 1所示， 为了节省天线空间， 可以将第一金属片垂直 于印刷电路板的其中一端折叠放置。 当然， 为了节省天线空间， 第一金属片垂 直于印刷电路板的其中一端还可以采用其它形状， 例如， 可以如图 2所示， 在 第一金属片垂直于印刷电路板的其中一端设置形成蛇形线的多个沟槽。 这样， 在有限的空间内就延长了第一金属片的长度， 达到了不增大天线体积， 而使天 线谐振在更低频率的目的。
具体实施时， 图 1中的单极子天线 101还可以包括：
第二金属片 101c， 放置于印刷电路板 102与第一金属片 101a之间， 与印刷电 路板 102垂直，平行且靠近印刷电路板 102的一条边与印刷电路板 102的接地 点相导通， 平行且远离印刷电路板 102的一条边悬空。
这样， 第二金属片作为单极子天线的寄生单元， 可以通过与第一金属片耦合， 谐振在第一金属片天线频率接近，或完全不同的一定频段，从而使天线的带宽 更宽。
一个实施例中， 为了节省天线空间， 图 1中第二金属片垂直于所述印刷电 路板的其中一端也可以折叠放置， 或者， 如图 2所示， 在第二金属片垂直于印 刷电路板的其中一端设置形成蛇形线的多个沟槽。 这样，在有限的空间内就延 长了第二金属片的长度， 达到了不增大天线体积， 而使天线谐振在更低频率的 目的。
另外， 为了调试天线的无线性能， 第一金属片与第二金属片之间缝隙的长 度和宽窄可以根据所述移动通信天线设备所需的无线性能进行调整。这是由于 第一金属片与第二金属片之间的缝隙存在电容效应，因此调整缝隙的长度和宽 窄， 电容容值就会相应地改变， 从而使得天线的无线性能随之改变。 这里的无 线性能可以包括天线的电压驻波比、 回波损耗、 增益、 效率等。
同样的，第二金属片与所述印刷电路板之间的缝隙的长度和宽窄根据所述 移动通信天线设备所需的无线性能进行调整，从而使天线的无线性能获得有益 的微调。
本发明实施例还提供一种移动通信终端设备，该设备可以包括上述移动通 信天线设备， 这样， 该移动通信终端设备的天线带宽也可得以增加， 通过实现 天线超宽带化，使移动通信终端设备产品，如固定台等支持更多频段成为可能； 并且， 天线的增益也可得以提高， 天线水平面方向图的不圓度得以改善。
除固定台外，本发明实施例方案也可应用于其他小型移动通信终端设备产 品上， 如无线 AP ( Access Point, 无线访问节点、会话点或存取桥接器）、 FMC ( Fixed Mobile Convergence， 固定网络与移动网络融合）终端、 数码相框等产 品形态上。
图 3 为本发明实施例中移动通信天线设备仿真得到的天线回波损耗结果 示意图， 由图 3 可以得知， 本发明实施例可实现移动通信天线设备频带覆盖 824 ~ 960MHz、 1710 ~ 2484MHz,满足目前终端设备常用的 GSM850、GSM900、 DCS, PCS, UMTS2100频段， 以及 GPS、 Bluetooth等频段。 同时， 天线的增 益能够达到常规的外置天线水平。尤其是天线水平面方向图的不圓度与已有内 置天线形式相比， 有了较大改善， 使得用户使用体验效果有较大提升。 本发明 实施例结构简单易行， 成本较低。
综上所述，本发明实施例采用将单极子天线放置在距印刷电路板中心位置 小于阔值的设定范围以内，并采用与印刷电路板相导通的金属寄生地的方式实 现了天线的超宽带化，使移动通信终端设备产品， 如固定台等支持更多频段成 为可能； 实现了固定台等移动通信终端设备产品的天线高增益， 并改善了天线 水平面方向图的不圓度； 实现主天线与 GPS、 Bluetooth天线等的共用， 降低 天线成本。 另外， 还在印刷电路板与第一金属片之间设置第二金属片， 作为单 极子天线的寄生单元，通过与第一金属片耦合，谐振在第一金属片天线频率接 近， 或完全不同的一定频段， 从而使天线的带宽更宽。 以上所述的具体实施例，对本发明的目的、技术方案和有益效果进行了进 一步详细说明， 所应理解的是， 以上所述仅为本发明的具体实施例而已， 并不 用于限定本发明的保护范围，凡在本发明的精神和原则之内，所做的任何修改、 等同替换、 改进等， 均应包含在本发明的保护范围之内。
