Description

一种天线去耦装置、天线阵列及终端
交叉引用
本发明要求在2019年08月23日提交中国专利局、申请号为201910786001.6、发明名称为“一种天线去耦装置、天线阵列及终端”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本发明涉及5G领域、通信领域与信号检测领域，特别涉及一种天线去耦装置、天线阵列及终端。
背景技术
随着当下4G(第四代通信系统)的迅速发展与成熟，频率资源紧缺、能源的巨大消耗以及网络的优化问题，一些新兴的移动通信业务对移动通信网络的发展提出了新的需求，更宽的频段带宽、更高速率数据通信服务、超高的连接数密度和超低的时延等，促生了5G(第五代通信系统)的研究和发展。提供数GB级数据服务的5G通信将给用户带来全新的体验。在能支持5G通信系统的终端中，目前流行的4GLTE通讯系统将被保留，在未来的终端中，4GLTE将会和5G共存。这无疑对智能终端设备提出了更高的要求，就空中接口而言，可兼容5G通信频段并且包含MIMO天线阵，通过使用空间复用和减轻干扰，是解决无线数据服务指数增长问题的最重要的技术之一。要在终端产品中集成大规模MIMO天线阵，其互耦严重，干扰大，会降低整个天线效率，甚至直接影响到5G系统的性能指标。所以提高天线间的隔离度是5G天线阵的关键。
现阶段，对于可应用于移动终端的5G天线阵的研究还是集中于天线的 小型化，多频段，以及隔离度这几个方面。在像手机这样的小型手持终端放置多个天线是很困难的，因为手机的尺寸本身就很小，放置在手机内的天线单元之间间距小，故而，天线与天线之间以及天线和手机地板之间有电流流过使得它们之间存在强烈的互耦效应，从而影响了天线的效率。因此，天线单元之间的去耦合也是5G天线阵的研究重点之一。
目前提高天线间隔离度的方法有：中和线去耦法，地板开缝法，地板枝节法，去耦网络法等，这些方法解决的隔离度问题有限，天线间的干扰无法完全抑制。
对于现在5G通信的MIMO天线阵要求的天线数目更多，在有限尺寸上集成更多的天线将难以实现，所以对天线隔离度提出了更高的要求。
针对上述急迫需要解决的天线阵列间高隔离度问题，现有方案很难有效解决5G通信时代有限空间天线数目增加、互耦效应变强的问题。4G、5G过渡阶段，高频、低频天线共存，多个频道天线共存不仅需要解决尺寸问题，相互之间会不断的产生信号干扰，天线之间的互耦效应变强，多个天线带来信号干扰不断、互耦效应增强的问题将严重影响通讯效果和用户体验。
