Description

一种多入多出天线装置 技术领域
本发明涉及移动通信技术， 尤其涉及一种多入多出 （Multiple Input and Multiple Output, 简称 MIMO )天线装置。 背景技术
目前移动通信网络已经发展到了第三代移动通信网 （The third Generation Mobile Telecommunication , 简称 3G ) ， 3G网络已经在 世界范围内大规模部署并商用。 随着数据业务及移动互联网的不断普 及和推广，国际通信标准组织正在制定移动通信长期演进（ Long Time Evolution, 简称 LTE )及 4G等技术标准， 以满足网络技术和服务能 力地不断发展。 由于 MIMO技术可以充分使用独立空间传播路径来 大大提升网络服务速率和链路性能，成为在 LTE及未来 4G技术中最 关键的核心技术之一。
目前 2G及 3G网络大多数使用低频段资源， 例如全球移动通信 系统（ Global System for Mobile communications , 简称 GSM )使用 900MHz 和码分多址接入 ( Code Division Multiple Access , 简称 CDMA )使用 800MHz， 而 LTE和 4G未来将很大可能使用 2GHz以 上频段， 这样 2G和 3G网络的信号传播将优于 LTE和 4G系统。
在目前基站站址很难增加的情况下，运营商一般会采用多系统共 基站建设方案来部署 LTE和 4G网络， 这样 LTE和 4G系统就需要 通过 MIMO多天线技术来增强覆盖以达到与 2G/3G基站同覆盖水平， 这将使得 LTE和 4G系统的 MIMO天线数尽可能的增多来提升 LTE 和 4G系统覆盖水平。
对于 MIMO技术应用， 需要在发射机与接收机之间存在多个不 同的空间传播路径， 多个发射机与接收机之间的空间信道相关性直接 影响到 MIMO技术性能和使用效率。 针对 MIMO的使用条件， 现有 的 MIMO多天线部署方案一般是采用多根天线之间拉开一定的水平 距离， 以利用水平隔离的方案来产生 MIMO 的弱相关性信道， 从而 最终保证 MIMO技术的使用性能。 但是， 这种方案对于运营商部署 网络来说， 会造成很大的难度。 因为现在人们对于电磁辐射问题的高 度关注， 很多基站站址很难增加天线数量， 同时很多基站天面很难有 足够的空间来保证多根天线的水平隔离距离， 特别是当 MIMO天线 数要求达到 4根及 4根以上的场景。 因此， 需要设计不同的 MIMO 天线实现方案来解决这个问题，以保证未来 LTE和 4G网络的顺利部 署。 发明内容
本发明的目的是提出一种多入多出天线装置，仅占用较小的基站 天面空间进行部署。
为实现上述目的， 本发明提供了一种多入多出天线装置， 包括： 在垂直方向上隔离布置的至少两个默极化天线单元，至少两个双 极化天线单元与地面法线之间的倾角均一致， 所述默极化天线单元包 括多个垂直排列的天线阵子；
其中，所述至少两个默极化天线单元中相邻默极化天线单元的相 邻边缘天线阵子的间距 d为 0.7 λ ~1 λ， λ为天线支持频段中心频点 波长。
优选的， 所述双极化天线单元的模式采用 +45度和 -45度极化方 式。
进一步的，还包括将所述至少两个默极化天线单元统一封装的天 线外革。
进一步的，所述默极化天线单元包括的天线阵子的数目由天线增 益值确定， 所述至少两个默极化天线单元构成的多入多出天线装置的 总长度由所述天线阵子的数目确定。
可选的， 所述默极性天线单元为两个，分别为在垂直方向上下隔 离的上天线单元和下天线单元。
进一步的，所述上天线单元和下天线单元与不同频段网络天线单 元并排封装在同一天线外革中。
基于上述技术方案， 本发明所采用的垂直隔离模式的 MIMO天 线可以解决水平隔离模式下 MIMO天线存在的占用较多基站天面空 间的问题， 而也易于保证多个默极化天线单元的倾角一致性， 并且通 过上下垂直隔离的方式来实现 MIMO天线的空间信道弱相关性。 附图说明
此处所说明的附图用来提供对本发明的进一步理解，构成本申请 的一部分， 本发明的示意性实施例及其说明用于解幹本发明， 并不构 成对本发明的不当限定。 在附图中：
图 1为本发明多入多出天线装置的一实施例的结构示意图。 图 2为本发明多入多出天线装置的另一实施例的结构示意图。 图 3为本发明多入多出天线装置的又一实施例的结构示意图。 具体实施方式
下面通过附图和实施例，对本发明的技术方案做进一步的详细描 述。
如图 1所示，为本发明多入多出天线装置的一实施例的结构示意 图。 在本实施例中， 采用了不同以往的垂直隔离布置的方式， 即将至 少两个默极化天线单元进行如图 1所示的垂直排列， 图 1中示出的是 两个默极化天线单元组成的 MIMO天线装置的例子， 在该例子中， 在靠上方的默极化天线单元被简称为上天线单元 10，靠下方的默极化 单元被简称为下天线单元 20，上天线单元 10和下天线单元 20均由多 个垂直排列的天线阵子 30组成， 上天线单元 10和下天线单元 20在 垂直方向上形成垂直隔离， 由于每个天线阵子均包括两个不同角度的 极化方式， 因此形成了 4根弱空间相关性的 MIMO天线装置， 从而 适合目前各种主流的 MIMO天线设计， 例如 4 x 2、 4 4 MIMO天线 设计方案等。
为了实现较好的 MIMO性能， 还要保证至少两个默极化天线单 元与地面法线之间的倾角均一致， 从而提高至少两个默极化天线单元 的重叠覆盖区域。而每个双极化天线单元的模式优选采用 +45度和 -45 度极化方式。 这里的角度指的是天线的极化方向， 也就是表示天线的 信号波将会以正负 45度极化方向发出， 产生两个相互正交的信号波， 由于两个信号波的极化方向的差别， 就减弱了两路信号的相关性， 从 而产生弱相关信道。
本实施例采用了垂直隔离方式，只是在天线长度上有所增加， 而 不会像现有的水平隔离模式的 MIMO天线对基站天面提出空间要求， 也更容易保证至少两个默极化天线单元的倾角一致性。 对于更多天线 的 8 x 2、 8 X 4 MIMO天线等， 只需将水平隔离和垂直隔离结合起来， 在基站天面上水平隔离部署两套垂直隔离的天线， 而无须在水平上水 平隔离部署 4根天线， 从而降低了在更多 MIMO天线配置模式下对 于基站天面空间的要求。
在本发明实施例中， 由于受到天线阵子自身半径（0.5倍波长） 长度的限制， 如果将垂直隔离间距设定为 0.5倍波长， 则天线阵子将 互耦严重， 各个阵子的辐射效率将会下降， 天线整体增益也将降低， 因此至少两个默极化天线单元中相邻默极化天线单元的相邻边缘天 线阵子 （如图 1所示的 d ) 的间距（1>0.5 λ， λ为天线支持频段中心 频点波长， 过短的垂直隔离间距也无法达到行业标准规定的天线端口 隔离度要求。 换句话说， 这里的间距指的图 1实施例中的上天线单元 10的最下面的天线阵子和下天线单元 20的最上面的天线阵子之间的 距离， 这个间距应至少 0.5倍的天线支持频段中心频点波长。 该间距 优选为 0.7 λ ~1 λ， 可以基本消除天线阵子互耦现象， 满足弱空间相 关性， 而过大的垂直隔离间距（例如 4-7倍波长等）则会导致天线副 瓣变大， 降低天线增益， 另外， 还会导致天线过长， 进而提高对天线 抱杆的稳定性要求， 增加工程实施成本和实施难度， 导致因形成过长 的天线而难以部署的问题。
如图 2所示，为本发明多入多出天线装置的另一实施例的结构示 意图。 与上一实施例相比， 本实施例将基于垂直隔离模式的至少两个 默极化天线单元统一封装到一个天线外革中， 即将上天线单元 10和 下天线单元 20统一封装到天线外革 40中， 而上天线单元 10和下天 线单元 20采用各自的馈电网络， 从而实现 MIMO天线的集成化， 从 外形上这种 MIMO天线装置可看作一根天线， 因此在架设安装时可 以只使用一根抱杆， 而无需更多的抱杆建设， 此外封装到同一个天线 外革则更容易保持所有的默极化天线单元具有相同的下倾角和方位 角， 各参数一致性更好， 从而提高了 MIMO性能。
现有的水平隔离天线的两根天线需要分别固定在两根抱杆上，很 容易引入两个抱杆之间的误差， 导致天线下倾角的不一致。 而本实施 例可以很好地克服这种现有技术的缺陷。
对于 MIMO天线装置来说， 默极化天线单元包括的天线阵子的 数目由天线增益值确定， 至少两个默极化天线单元构成的多入多出天 线装置的总长度由天线阵子的数目确定。一般来说， 15dBi天线由 4~6 个天线阵子组成， 18dBi由 8~12个天线阵子组成， 每增加 3dBi， 就 会增加一倍天线阵子数目， 根据现在天线设计工艺， 一般天线阵子间 距可以取为 0.7 λ ~1 λ， 即 0.7~1倍的天线支持频段中心频点波长。
各个天线阵子的间距再加上天线外革的边框长度以及默极化天 线单元之间的间距等， 则可以计算出总的 MIMO天线装置的总长度。 对于现有的 2G/3G网络来说， 由于使用的频点为低频段， 因此天线总 长度会更长， 而对于 LTE和 4G网络来说， 由于频点升高， 则会使得 天线尺寸变小， 就可以避免天线过长的问题， 也就是说， 本发明将更 加适合在使用 2GHz以上频点的网络中应用。
如图 3所示，为本发明多入多出天线装置的又一实施例的结构示 意图。 与之前各实施例相比， 本实施例将上天线单元 10和下天线单 元 20与不同频段网络天线单元（如图 3中的 2G/3G天线单元 50 )并 排封装在同一天线外革 40 中， 从而形成集成化的天线装置， 天线外 革 40的长度可选取整体长度较大的值， 上天线单元 10和下天线单元 20构成的垂直隔离布置结构与 2G/3G天线单元之间的水平间距只需 保证两个系统收发信号的独立性即可。 从外观上看， 这种集成化的天 线装置被看作一根天线， 在布置安装时更加方便。
另外， 如果 MIMO天线采用的是 LTE/4G网络等使用的较高频 点， 每个天线单元的长度均较短， 因此采用上下隔离布置的方式形成 的整体 MIMO天线结构与采用 2G/3G网络等使用的较低频点的天线 长度不会有较大差距， 从而有效的利用了天线长度区别不大的特点， 将两者集成起来， 而不会大幅增加这种共天线结构的天线长度。
最后应当说明的是:以上实施例仅用以说明本发明的技术方案而 非对其限制； 尽管参照较佳实施例对本发明进行了详细的说明， 所属 领域的普通技术人员应当理解： 依然可以对本发明的具体实施方式进 行修改或者对部分技术特征进行等同替换； 而不脱离本发明技术方案 的精神， 其均应涵盖在本发明请求保护的技术方案范围当中。
