Abstract

本公开提供一种WIFI&GPS天线，应用在金属机身的移动终端上，所述天线包括馈电点及接地点，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，所述收容区具有左右两侧边及与两侧边连接的顶边，所述侧边上设有断缝，所述馈电点及接地点均设置在机身本体上，所述馈电点上串联设有一与所述顶边相接的容性调谐元件，所述收容区分为器件区与天线区，馈电点及接地点设置在远离器件区的天线区。本申请通过在WIFI&GPS天线的馈电点和边框之间的走线中，加入一容性调谐元件，且在馈电点侧边放置接地点，从而使WIFI和GPS天线都只使用同侧边断框枝节作为主要辐射体，不受中间摆放器件的影响，提高了WIFI和GPS天线性能。

Description

一种WIFI＆GPS天线
技术领域
本申请涉及一种天线，尤其是一种WIFI&GPS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。
由于GPS频率较低(1575MHz)，波长较长，一般需使用到断框的中间区域作为天线的一部分，但是断框的中间区域一般摆放有Receiver、前置摄像头等金属器件，会影响GPS的性能。因此需要研发一种在不增加天线所需空间的基础上能保证其性能的新型天线。
发明内容
为克服相关技术中存在的问题，本公开提供一种新型WIFI&GPS天线。
具体地，本申请是通过如下技术方案实现的：一种WIFI&GPS天线，应用在金属机身的移动终端上，所述天线包括馈电点及接地点，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，所述收容区具有左右两侧边及与两侧边连接的顶边，所述侧边上设有断缝，所述馈电点及接地点均设置在机身本体上，所述馈电点上串联设有一与所述顶边相接的容性调谐元件，所述收容区分为器件区与天线区，馈电点及接地点设置在远离器件区的天线区。
可选的，所述容性调谐元件为0.1-1.5PF的电容。电容越大，GPS天线和WIFI天线的路径长度越短，但是其辐射效率也会下降，本申请中优选0.5PF左右的电容。
可选的，所述馈电点靠近侧边断缝设置，并利用断缝构成一个IFA形式的天线以传输WIFI信号。
可选的，所述接地点设置在天线区靠近器件区的位置，馈电点与收容区的顶边及接地点构成一个LOOP形式的天线传输GPS信号。因为在馈电点与金属边框之间设置了电容元件，有效缩短了GPS天线的总路径。
可选的，所述馈电点到接地点的总路径长度小于GPS工作频率的半波长。
可选的，所述断缝的宽度为0.5mm-1.5mm，本申请中断缝宽度优选为0.8mm。
可选的，在所述接地点靠近器件区的一侧增设有若干接地点。以提高WIFI、GPS天线跟左边其它天线间的隔离度或者金属器件对天线使用环境的不利影响。
附图说明
图1是根据一示例性实施例示出的一种WIFI&GPS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WIFI&GPS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及接地点2，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4，所述收容区具有左右两侧边40及与两侧边连接的顶边41，所述侧边40上设有断缝，所述馈电点1及接地点2均设置在机身本体上，所述馈电点1上串联设有一与所述顶边41相接的容性调谐元件3，所述收容区分为器件区与天线区，馈电点1及接地点2设置在远离器件区的天线区。
所述容性调谐元件为0.1-1.5PF的电容。电容数值选择越大，GPS天线和WIFI天线的路径长度越短，但是其辐射效率也会下降，会影响天线的使用效果，本申请中优选0.5PF左右的电容。
所述馈电点1靠近侧边断缝设置，并利用断缝构成一个IFA形式的天线以传输WIFI信号。所述WIFI天线充分利用侧边断缝末端进行辐射，减少了WIFI天线的路径。
所述接地点设置在天线区靠近器件区的位置，馈电点与收容区的顶边及接地点构成一个LOOP形式的天线传输GPS信号。因为在馈电点与金属边框之间设置了电容元件，有效缩短了GPS天线的总路径。在所述接地点靠近器件区的一侧增设有若干接地点。以提高WIFI、GPS天线跟左边其它天线间的隔离度或者金属器件对天线使用环境的不利影响。
所述馈电点到接地点的总路径长度小于GPS工作频率的半波长。
所述断缝的宽度为0.5mm-1.5mm，本申请中断缝宽度优选为0.8mm。断缝太窄不利于天线辐射效果，断缝太宽影响手机产品外观。
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。
