Description

一种金属外壳手持式多天线终端 技术领域
本发明涉及一种金属外壳手持式多天线终端，属于物联网与微波技术领域。
背景技术
进入21世纪以来，随着无线通信技术的飞速发展，MIMO技术得到越来越广泛的应用，它利用发射端和接收端分别使用多个发射天线和接收天线，信号通过发射端和接收端的多个天线传送和接收，在不增加频谱资源和天线发射功率的情况下，可以成倍提高系统信道容量和通信质量，实现更高用户速率，被视为下一代移动通信的核心技术。
由于手持移动终端的的尺寸有限，随着天线单元的增加，天线单元相互之间距离变近，各个单元之间的相关性有很大提高，从而影响相邻天线的电流，这就是互耦效应。因而在有限空间降低天线的互耦效应，提高天线间的隔离度是设计MIMO天线的一大难点。
常用的降低天线之间互耦效应的方法有三类：(1)端口解耦合，在天线端口采用复杂的解耦网络来进行端口解耦合，在实际工程应用中可以采用加载电容的方法达到天线的隔离，从而降低天线耦合；(2)极化解耦合法，采用极化正交的方法解耦合；(3)地解耦合法，通过在地板上开槽并调整开槽的数量和开槽线之间的距离，可在两个天线之间形成一个谐振，可以降低两天线之间的耦合。
同时，手持终端越来越普及，它们开始在人们的生活中充当各种角色，使它成为人们生活中的最重要的一部分。人们对终端的要求不仅是功能强大，还需要外形靓丽，这时，采用不同的终端外壳是否会对天线接收和传输信息产生影响，也是我们需要考虑的问题。

具体实施方式
下面结合附图对本发明的技术方案做进一步的详细说明：
对照附图1、图2，本发明一种金属外壳手持式多天线终端的结构是：介质基板14放在金属外壳10中，且介质基板14与金属外壳之间存在一定的间隙。金属外壳包括边框9以及背壳10，在边框9上还设置有开槽。
单位天线磁偶极子1～8制作在介质基板14上，并由金属过孔、顶层E形金属贴片12与底层E形金属贴片13构成，磁偶极子通过金属过孔形成一个三面封闭的结构，非封闭面为E形金属贴片的开口方向。磁偶极子1～8的结构和尺寸完全相同，并关于介质基板的两条对称轴呈均匀对称分布；顶层E形金属贴片12与底层E形金属贴片13的结构和尺寸完全相同，并分别在介质基板的顶层和底层均匀对称布置。每个磁偶极子均通过同轴线11进行馈电，同轴线11的内芯连接顶层E形金属贴片12与底层E形金属贴片13。
顶层E形金属贴片12是金属层D15的一部分。
附图3是利用IE3D软件计算的天线反射系数，S(1，1)表示单元天线磁偶极子1的反射系数，S(2，2)表示磁偶极子2的反射系数，根据附图3的结果可见，该天线带宽覆盖了频段3.44GHz～3.56GHz，相对带宽为3.4％，中心频率在3.5GHz附近，该天线具有一定的阻抗带宽。
对照附图4和图5给出不同的单位天线磁偶极子之间的隔离度，介质基板14按照相对介电常数为4.3、厚为2毫米，单元天线磁偶极子之间的隔离度。附图4给出磁偶极子1与磁偶极子2和5之间的隔离度，分别用S(1，2)和S(1，5)表示；附图5给出了磁偶极子2与单元天线磁偶极子1和6之间的隔离度，分别用S(2，1)和S(2,6)表示。观察可得，它们在反射系数的带宽给定的情况下，单元天线的隔离度一般为10dB以上，具有良好的隔离特性。
本发明实现的多天线系统利用印刷板厚度方向的等效磁流进行辐射，能够防止金属外壳劣化天线性能，降低手握对天线性能的影响，结构简单、用常规工艺即可实现，无需增加馈电附件，因此在未来无线通信多天线手持终端的设计中有广泛应用前景。
