Description

多天线系统及移动终端 技术领域
本发明涉及无线通信技术领域，尤其涉及一种移动终端的多天线系统。
 背景技术
随着5G通信技术的蓬勃发展，对5G通信技术的研究越来越重视。多输入多输出(MIMO: Multiple-Input Multiple-Output)技术是5G天线的核心技术，多天线的实现是MIMO技术的基础。
而随着移动终端的设计越来越趋于超薄化，受到移动终端大小尺寸的限制，天线的排布必然紧密，这就带来相近天线，相同频段之间的互耦干扰强烈的问题。
相关技术中，为了解决多天线之间的互耦干扰问题，主要通过拉大天线间的间距来改善，但受到设备尺寸的限制，拉开的间距有限，还有通过在天线间引入中和线来解决，但是中和线技术对天线要求严苛，且中和线的长度需要达到一定长度才能达到效果。
因此，有必要提供一种新的多天线系统解决上述问题。
 技术问题
发明需要解决的技术问题是提供一种多天线系统，旨在增加两天线之间的隔离度，以降低相邻两天线之间的互耦干扰，提高天线性能。
 技术解决方案
为解决上述技术问题，本发明提供一种多天线系统，其包括至少两个天线单元和连接相邻两个所述天线单元的中和线，且所述中和线上设置有电感元件。
优选的，所述天线单元的数量大于两个，每相邻两个所述天线单元之间均连接有所述中和线，且每一所述中和线上均设置有电感元件。
优选的，所述电感元件的电感值为10nH-50nH。
优选的，所述电感元件设置于所述中和线的中点位置。
优选的，所述电感元件为电感、线圈或微带线中的任意一种。
优选的，所述多天线系统为8*8MIMO多天线阵列。
优选的，所述8*8MIMO多天线阵列的工作频段为3.4-3.6GHz和/或4.8-5.0GHz。
优选的，所述天线单元为FPC天线。
本发明还提供一种移动终端，其包括上述任一项所述的多天线系统。
 有益效果
与相关技术相比，本发明提供的多天线系统及移动终端具有如下有益效果：
1）通过在相邻两个天线单元之间设置连接二者的中和线且中和线上设置有电感元件，该具有电感元件的中和线可以显著增加天线单元之间的隔离度，从而降低天线单元之间的互耦干扰，提高天线性能；
2）电感元件可以缩短中和线的长度，可以为移动终端其它电子元器件布设提供空间，有助于移动终端微型化。
 附图说明
图1为本发明实施例所提供的移动终端的部分结构示意图；
图2为图1所示A部分的局部放大图；
图3为图1所示移动终端中多天线系统的原理图；
图4为本发明实施例所提供的多天线系统与现有多天线系统的隔离度对比图；
图5为本发明实施例所提供的多天线系统多天线系统与现有多天线系统的天线效率对比图。
 本发明的实施方式
下面将结合附图和实施方式对本发明作进一步说明。
如图1-2所示，本发明实施例提供了一种移动终端100，其包括多天线系统，此多天线系统可以接收和发送电磁波信号，进而实现移动终端的通信功能，此处的移动终端可以是手机、ipad以及POS机等，本发明对此不作限定。
具体地，所述多天线系统包括PCB板1、与所述PCB板1的接地线连接的多个天线单元2、连接相邻两个所述天线单元2的中和线3和设置于所述中和线3上的电感元件4，所述PCB板1即为移动终端的主板。在本实施例中，所述天线单元2的数量为四个，每相邻两个所述天线单元2之间均连接有所述中和线3，通过所述中和线3将相邻两个所述天线单元2连接在一起，所述中和线3在天线的工作频段产生谐振形成高阻结构，能够改变电流在二者之间的传导，能够降低相邻两个所述天线单元2之间的耦合干扰。由于所述中和线3要达到一定长度才能降低耦合干扰，而受到设备尺寸的限制，所述中和线3的长度有限，为此，本发明通过在所述中和线3上设置电感元件4来增加所述中和线3的内阻，从而增大天线单元之间的隔离度，降低耦合干扰。其中所述电感元件4可以是电感、线圈或微带线中的任意一种，其电感值控制在10nH-50nH。
本实施例中为了更好的说明本发明的思想，以下结合图3对本发明的原理进行阐述，参照图3，为图1所示移动终端中多天线系统的原理图，以任意相邻两个天线单元为例，分别定义为第一天线单元21和第二天线单元22，其中所述第一天线单元21和第二天线单元22分别放置于PCB板的同一端并共用所述PCB板的接地线，如果不采取任何的隔离措施，则在所述第一天线单元21的第一馈电端211和所述第二天线单元22的第二馈电端221之间形成很强的耦合电流，这就导致所述第一天线单元21和所述第二天线单元22之间的相互信号干扰比较严重，而在所述第一天线单元21和所述第二天线单元22之间设置连接二者的中和线3，且所述中和线3上设置有电感元件4，等效于在所述第一天线单元21和所述第二天线单元22之间设置一高阻结构，因此，有效地减少所述第一天线单元21与所述第二天线单元22之间的相互耦合，进而有效防止所述第二天线单元21与所述第二天线单元22之间的相互信号干扰。
由此，虽然相邻两个所述天线单元2之间是共地结构，但由于采用了带有电感元件4的中和线3进行隔离，使得两个天线单元2之间的互扰大大降低。
在本实施例中，所述天线单元2优选为FPC天线，当然其也可以为其它天线形式，对此本发明作限制。
进一步地，所述电感元件4通常设置在所述中和线3的中点位置，其可以直接布设在PCB板上，不影响移动终端其它电子元器件的布设。
更进一步地，所述多天线系统包括8个天线单元，所述多天线系统为8*8MIMO多天线阵列，其工作频段为3.4-3.6GHz和/或4.8-5.0GHz。
图4示出了本发明实施例所提供的多天线系统与现有多天线系统的隔离度对比图，其中实线和虚线分别代表不加中和线和加入改进的中和线（在中和线上设置电感元件）时的隔离度，从图4中可以看出，加入改进的中和线后，隔离度的绝对值明显增大，说明天线单元之间的隔离度增大，从而有效降低天线单元之间的互耦干扰。
图5示出了本发明实施例所提供的多天线系统与现有多天线系统的天线效率对比图，其中实线和虚线分别代表不加中和线和加入改进的中和线（在中和线上设置电感元件）时的天线效率，从图5中可以看出，加入改进的中和线后，在工作频段3.4-3.6GHz和4.8-5.0GHz，天线效率明显提高，说明加入改进的中和线后提高了天线性能。
与相关技术相比，本发明提供的多天线系统及移动终端具有如下有益效果：
3）通过在相邻两个天线单元之间设置连接二者的中和线且中和线上设置有电感元件，该具有电感元件的中和线可以显著增加天线单元之间的隔离度，从而降低天线单元之间的互耦干扰，提高天线性能；
4）电感元件可以缩短中和线的长度，可以为移动终端其它电子元器件布设提供空间，有助于移动终端微型化。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本发明的专利保护范围内。
