Description

多天线终端 技术领域 本发明涉及多天线终端技术领域， 特别涉及一种多天线终端。 背景技术 多输入多输出 (Multi-Input Multi-Output, 简称为 MIMO)或多发多收天线技术是无 线移动通信领域天线技术的重大突破。 该技术能在不增加带宽的情况下成倍地提高通 信系统的容量和频谱利用率， 是新一代移动通信系统必须采用的关键技术。 MIMO 技 术允许多个天线同时发送和接收多个空间流（频段）， 并能够区分发往或来自不同空间 方位的信号。 多天线系统的应用， 使得并行的数据流可以同时传送。 同时， 在发送端 或接收端采用多天线， 可以显著克服信道的衰落， 降低误码率。 但是在终端设备中， 尤其是手持终端受到产品外观以及尺寸的限制， 多天线在终 端产品中的实现有一定的难度。 为了解决这一技术难题， 传统的方法是将各个天线之 间的相互距离设置的尽量远， 使相邻两个天线的隔离度足够大， 这样布局是可以达到 一定的效果。 但是目前终端产品对外观要求越来越高， 产品的小型化已经成为未来必 然的趋势。 这就限定了天线之间的距离不可能放置的很理想， 由此， 不可避免的将出 现多个天线之间相互干扰的情况。而出现干扰的主要原因是各天线都是与 PCB板的共 地连接， 当相邻的两个天线接收信号时， 会在两个天线的馈电之间形成很强的耦合电 流， 这就导致两个相邻的天线之间出现互扰。 因此， 如何在较小的物理尺寸下， 防止多个天线之间相互干扰成为当下亟待解决 的问题。 发明内容 本发明实施例的主要目的为提供一种多天线终端， 旨在提高相邻两天线之间的信 号隔离效果， 以降低相邻两天线之间的信号互扰。 本发明实施例提出一种多天线终端， 该多天线终端包括 PCB板、 第一天线、 第二 天线， 电感元件、 第一开口谐振环组及第二开口谐振环组， 所述第一天线和第二天线 分别与所述 PCB板上的接地线连接，所述第一开口谐振环组及第二开口谐振环组设于 所述第一天线和第二天线之间； 所述第一开口谐振环组和第二开口谐振环组并行设置 且分别与所述 PCB板的接地线连接；所述电感元件的一端与所述第一开口谐振环组连 接， 另一端与所述第二开口谐振环组连接。 优选地， 所述第一开口谐振环组至少由一个单个开口谐振环组成， 所述第二开口 谐振环组至少由一个单个开口谐振环组成。 优选地， 所述第一开口谐振环组由多个单个开口谐振环串联组成， 所述第二开口 谐振环组由多个单个开口谐振环串联组成。 优选地， 所述单个开口谐振环由若干微带线组成。 优选地，所述第一开口谐振环组和第二开口谐振环组均为一侧设有凹口的矩形框， 所述凹口的底部设有缺口。 优选地， 所述电感元件设置在所述第一开口谐振环组和第二开口谐振环组之间。 优选地， 所述电感元件为微带线。 优选地， 所述第一天线和第二天线设置在所述 PCB板上的同一端。
本发明实施例提出的多天线终端， 通过在第一天线和第二天线设置第一开口谐振 环组和第二开口谐振环组， 并通过电感元件将第一开口谐振环组与第二开口谐振环组 相互连接， 使之形成 LC谐振回路， 因此， 能够对第一天线和第二天线进行有效的信 号隔离， 并使得相邻两天线之间的信号互扰程度降低。 附图说明 图 1是本发明多天线终端较佳实施例的结构示意图； 图 2是图 1中的局部放大图。
本发明目的的实现、 功能特点及优点将结合实施例， 参照附图做进一步说明。 具体实施方式 应当理解，此处所描述的具体实施例仅仅用以解释本发明， 并不用于限定本发明。 参照图 1及图 2所示， 图 1是本发明多天线终端较佳实施例的结构示意图； 图 2 是图 1中的局部放大图。 本实施例提出的多天线终端包括 PCB板 10、 第一天线 11、 第二天线 12、 电感元 件 20、第一开口谐振环组 21及第二开口谐振环组 22， 其中： 第一天线 11和第二天线 12分别与所述 PCB板 10上的接地线连接； 第一开口谐振环组 21及第二开口谐振环 组 22设于所述第一天线 11和第二天线 12之间； 所述第一开口谐振环组 21和第二开 口谐振环组 22并行设置且分别与所述 PCB板 10的接地线连接； 所述电感元件 20的 一端与所述第一开口谐振环组 21连接， 另一端与所述第二开口谐振环组 22连接。 由 于通过电感元件 20将第一开口谐振环组 21与第二开口谐振环组 22连接在一起，使得 第一开口谐振环组 21与第二开口谐振环组 22以及电感元件 20相互组成并联 LC谐振 回路， 而并联 LC谐振回路在谐振时等效为开路， 从而能够有效的隔离第一天线 11和 第二天线 12之间的耦合信号， 防止第一天线 11和第二天线 12相互干扰。 本实施例中， 第一开口谐振环组 21与第二开口谐振环组 22可以是圆形开口谐振 环、矩形开口谐振环或者其他任意适用形状的开口谐振环。其中电感元件 20可以是电 感、 线圈、 微带线或者其他任意适用的感性元件， 本实施例中， 所述电感元件 20优选 为微带线， 这是因为微带线具有体积小、 重量轻、 使用频带宽及可靠性高等优点。 本实施例中为了更好的说明本发明的思想， 以下以结合图 1来对本实施例进行详 细阐述， 参照图 1， 图 1是本发明多天线终端较佳实施例的结构示意图。 图 1中以第 一天线 11和第二天线 12为例，其中第一天线 11和第二天线 12分别放置于 PCB板 10 的同一端， 且第一天线 11和第二天线 12共用一块 PCB板 10的接地线， 如果不采取 任何的隔离措施， 则在第一馈电 30 (第一天线 11的供电输出） 和第二馈电 40 (第一 天线 12的供电输出） 之间将会形成很强的耦合电流， 这就导致第一天线 11和第二天 线 12之间的相互信号干扰比较严重，而在第一天线 11和第二天线 12之间设置相互连 接的第一开口谐振环组 21和第二开口谐振环组 22， 并且第一开口谐振环组 21和第二 开口谐振环组 22同时与 PCB板 10上的接地线连接， 等效于在第一天线 11和第二天 线 12之间做了一个并联的 LC谐振回路， 该 LC谐振回路可以在某个谐振点上谐振， 且在谐振的时候该 LC谐振回路等效于将第一天线 11和第二天线 12之间开路， 因此， 有效地减少了第一天线 11与第二天线 12之间的相互耦合， 进而有效防止第一天线 11 与第二天线 12之间的相互信号干扰。 其中， 对本领域的技术人员来说， 可以知晓： 所述第一开口谐振环组 21和第二开 口谐振环组 22可以分别由单个开口谐振环 23组成， 也可以分别是由多个单个开口谐 振环 23串联组成 （例如， 图 1和图 2所示的第一开口谐振环组 21和第二开口谐振环 组 22)。 以下以多个单个开口谐振环 23组成所述第一开口谐振环组 21和第二开口谐 振环组 22为例进行说明， 可以理解的是， 组成第一开口谐振环组 21和第二开口谐振 环组 22的单个开口谐振环 23数量根据两天线之间的分布位置及大小情况来具体设置， 并且第一开口谐振环组 21和第二开口谐振环组 22均连接至 PCB板 10的接地线上， 使得组成第一开口谐振环组 21的多个单个开口谐振环 23和组成第二开口谐振环组 22 的多个单个开口谐振环 23， 对第一天线 11和第二天线 12形成一个半包围结构， 从而 使得隔离的效果较好。 另外， 通过电感元件 20将第一开口谐振环组 21和第二开口谐 振环组 22相互连接， 使之组成 LC谐振回路， 当该 LC谐振回路与各个天线产生共振 时， 该 LC谐振回路等效于将第一天线 11和第二天线 12之间开路， 而该电感元件 20 的位置可以根据天线的谐振频率进行调整， 同时该电感元件 20也可以为多个，可以理 解的是， 为了减少成本及简化结构， 所述电感元件设置在所述第一开口谐振环组 11 和第二开口谐振环组 12之间。 由此， 虽然第一天线 11和第二天线 12虽然还是共地结构， 但是由于采用了 LC 谐振回路结构进行隔离， 使得两个天线之间的互扰大大降低。
优选地， 为了提高第一天线 11和第二天线 12之间的隔离效果， 所述单个开口谐 振环 23由若干微带线组成。 由于微带线具有使用频带宽及可靠性高等优点，从而使得 第一开口谐振环组 21和第二开口谐振环组 22组成的 LC谐振回路的内阻越大。
优选地， 为了提高第一天线 11和第二天线 12之间的隔离效果， 所述第一开口谐 振环组 21和第二开口谐振环组 22均为一侧设有凹口的矩形框， 所述凹口的底部设有 缺口。 这种结构产生的谐振频带宽， 形成的内阻大， 因此， 能够提高第一天线 11和第 二天线 12之间的隔离度。
优选地， 为了减少该多天线终端的体积， 且方便布局其他元件， 所述第一天线 11 和第二天线 12设置在所述 PCB板 10上的同一端。 由于采用该隔离技术后， 天线与天 线之间的隔离度较好， 即使设置在同一端也不会产生大的干扰。 以上所述仅为本发明的优选实施例， 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他 相关的技术领域， 均同理包括在本发明的专利保护范围内。 工业实用性 本发明实施例提供的技术方案可以应用于多天线终端技术领域， 解决现有技术的 多天线终端上的各天线之间信号相互干扰的问题， 从而更方便人们使用， 并且， 本发 明还具有结构简单、 成本较低等优点。
