Description

一种分集天线
技术领域
本申请涉及一种天线，尤其是一种全频段的分集天线。
背景技术
现在手机中的金属元素越来越多，全金属机身逐渐成为手机外观的主流，而金属的增多，会导致天线净空的减小，影响天线向外辐射和接收信号，这对天线设计提出了挑战。
从单个天线性能的角度考虑，净空越大、天线周边的环境中金属越少，性能就会越好，所以对于金属边框手机，如果能够将边框作为天线的一部分进行辐射，则可以实现较好的性能。
对于传统的LTE小天线，工作频率需要从700MHz覆盖到2690MHz全频段，一般情况下，即便使用手机金属边框作为天线的一部分辐射，带宽依然会非常有限，尤其是目前使用波段并不普遍的低频段效果会较差，因此仍然需要在手机内部其它地方额外布置线路，才能满足覆盖所需频段，而这些额外布置的线路只能设置在非边框的区域，因此所产生的谐振频率的效率势必会差些。
因此为了满足全频段都能良好使用，需要一种新型设计的天线。
发明内容
为克服相关技术中存在的问题，本公开提供一种能覆盖700MHz～2690MHz全频段的全金属机身手机分集天线。
具体地，本申请是通过如下技术方案实现的：一种分集天线，应用在金属机身的移动终端上，所述天线包括馈电点、第一接地点及第二接地点，所述金属机身包括机身本体及位于机身本体上方的收容区，所述收容区为侧边设有断缝的框形结构，所述馈电点、第一接地点及第二接地点均设置在机身本体上，所述馈电点上串联设有一与框形结构相接的容性元件，所述容性元件与框形结构的顶框相接用于切换分集天线的低频，使分集天线的高频覆盖1710-2690MHz，所述第一接地点上串联设有开关用于切换分集天线的不同低频，所述馈电点与断缝之间的距离为3mm-15mm，所述第一接地点与第二接地点设置在馈电点的同侧，且所述第一接地点设置在第二接地点与馈电点之间。
可选的，所述容性元件为可变电容；可变电容用于切换分集天线的低频，根据手机环境，通过变化不同的电容值，可以使分集天线高频覆盖1710-2690MHz。
可选的，所述开关为单刀单掷开关或单刀双掷；单刀双掷开关用于切换分集天线的低频，闭合时，低频工作在824-960MHz，断开时，低频工作在700-820MHz。
可选的，所述馈电点与第一接地点的总路径长度小于800MHz-960MHz的半波长。
可选的，所述馈电点与第二接地点的总路径长度小于700MHz-800MHz的半波长。
可选的，所述可变电容为悬空设置。
可选的，所述框形结构两侧边均设有断缝。
附图说明
图1是根据一示例性实施例示出的一种分集天线结构示意图。
具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
在本申请使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本申请可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
请参考图1所示，本申请一种分集天线，应用在金属机身的移动终端上，所述天线包括馈电点1、第一接地点2及第二接地点3，所述金属机身包括机身本体4及位于机身本体上方的收容区5，所述收容区为侧边设有断缝50的框形结构，所述馈电点1、第一接地点2及第二接地点3均设置在机身本体4上，所述馈电点1上串联设有一与框形结构相接的容性元件6，所述第一接地点2上串联设有开关7，所述馈电点1与断缝50之间的距离为3mm-15mm。
所述容性元件6为调谐元件，通常设置成可变电容，其与框形结构的顶框相接；所述可变电容用于切换分集天线的低频，能够使手机根据即时的使用环境，变化不同的电容值，从而有效保证分集天线高频覆盖1710-2690MHz。
所述开关为单刀单掷开关或单刀双掷；其用于切换分集天线的低频，当开关闭合时，低频工作频率为824-960MHz可称为第一低频频率，当开关断开时，低频工作频率为700-820MHz可称为第二低频频率。
所述第一接地点2与第二接地点3设置在馈电点1的同侧，且所述第一接地点2设置在第二接地点3与馈电点1之间，所述馈电点与第一接地点的总路径长度小于800MHz-960MHz的半波长，所述馈电点与第二接地点的总路径长度小于700MHz-800MHz的半波长；在实际的设计中，可以通过调整第一接地点与馈电点的距离来调整第一低频工作频率，通过调整第二接地点与馈电点的距离来调整第二低频工作频率。
所述电容为悬空设置，电容的一端可通过螺丝与螺母固定在框形结构的顶框上，也可直接一体成型在顶框上。
所述框形结构两侧边均设有断缝，可以充分利用手机断缝进行辐射，能有效减少天线体积，并保证天线的使用性能。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本申请保护的范围之内。
