Description

一种可调谐天线及手机 技术领域
本申请涉及但不限于无线技术领域。
背景技术
现有技术中，手机项目越来越多的把USB器件设置在底部；同时，手机的天线也通常设置在底部；随着USB TYPE-C接口的广泛应用，USB对与其相邻设置的天线设计和天线性能所产生的影响也就越来越大。为了能够优化设置天线模块以及USB模块，目前常用的做法是，将USB的外体金属部分作为天线的一部分，或者是一部分辐射体，或者是作为一个壳体上的天线和印刷电路板(PCB，Printed Circuit Board)上天线连接的载体；也可以将天线设置为避让开USB，基于天线所处的空间有限，以及天线性能对天线和USB间距敏感特性，上述设置并不能实现远距离的避让，也并不能有效解决因USB插入所造成的天线性能下降问题。
相关的优化方案包括有，针对天线本身进行调谐，或者引入传感器，以判断手机目前处于靠近人头的打电话状态，还是手持状态或是待机状态，针对这几种状态分别写入对应的天线参数，当传感器检测到相应的状态后调用相应的参数。具体操作中，天线的调试基于USB处于空置状态的情况进行调试；当USB线插入时，天线的驻波比仍旧会发生很大的变化，同时天线的性能也依旧发生了变化；因天线驻波比的偏移和USB线工作时带来的数字干扰将使天线性能急剧下降，并对用户的实际通话质量造成很大的影响。

附图概述
图1为本发明实施例的结构示意图一；
图2为本发明实施例的结构示意图二。
本发明的较佳实施方式
下面结合附图对本发明的实施方式进行描述。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的各种方式可以相互组合。
结合图1所示、图2所示，
本发明实施例提供了一种可调谐天线，可以设置主板9和天线本体1；其中，天线本体1与主板9之间设置有第一连接结构和第二连接结构，未插USB线时，所述天线本体1通过所述第一连接结构与所述主板9连接；USB线插入时，所述天线本体1通过第二连接结构与所述主板9连接。进一步的，主板9上设置有控制电路8和调谐开关电路7，控制电路8设置为当检测USB有线插入时，通过所述调谐开关电路7控制所述第一连接结构切换至第二连 接结构。
具体操作中，当USB10的端口位置处有线11插入时，控制电路8能够及时检测，并控制天线本体1与主板9之间的连接结构进行相应切换操作，以实现消除因USB有线插入所带来的天线本体1驻波比偏移；通过上述操作，能够实现天线状态以及性能保持稳定，能够使得天线本体1在USB有线插入状态或者USB没有线插入状态下，均能具有较好的辐射效率。另外，本申请中，上述天线本体1可以通过信号线2与主板9的射频通道连接。
为了能够详细说明上述连接结构的切换，本申请提出了如下技术方案：调谐开关电路7中的开关与端口之间有两种接入状态：第一接入状态和第二接入状态，第一接入状态为开关与端口之间的初始连接状态。相应的，第一连接结构设置为天线本体1通过地信号与调谐开关电路7连接，调谐开关电路7设置为第一接入状态；第二连接结构设置为，天线本体1通过地信号与调谐开关电路7连接，调谐开关电路7设置为第二接入状态。
具体操作中，本领域的技术人员可以赋予上述调谐开关电路7中各个端口不同的值，并通过上述调谐开关电路7中的开关，接通不同的端口，实现不同状态的切换，最终实现插入USB线后天线驻波比产生的偏移修正。
为了能够详细说明上述连接结构的切换，本申请还提出了如下方案：天线本体1设置有第一地信号3以及第二地信号4。相应的，第一连接结构设置为，天线本体1通过第一地信号3与调谐开关电路7连接，天线本体1通过第二地信号4与主板9的地线连接；第二连接结构设置为，第一地信号3与调谐开关电路7断开，天线本体1通过第二地信号4与主板9的地线连接。
具体操作中，本领域的技术人员可以通过上述天线本体1的两个地信号的切换连接，进行相应的天线调试，以实现插入USB线后天线驻波比产生的偏移修正。
进一步的，本申请通过如下的具体实施例进行详细说明：
第一具体实施例：
天线本体1处于非USB插入状态时，天线本体1通过信号线2与主板9 的射频通道相连，第一地信号3通过接线5与调谐开关电路7相连；其中，调谐开关电路7内设置有单刀多掷开关，并将开关打到a端口。本示例可以有接线6，也可以没有。如果有，接线6就是一直接地的状态。接线5与调谐电路7一端口固定连接的，上述单刀多掷开关可以将该端口与a,b,c,d,e,f中的一个端口连接。
当控制电路8检测到USB有线11插入时，调谐开关电路7中的开关断开与a端口的连接，打到b端口，并与b端口建立连接；其中，a端口与b端口被赋予有不同的值。端口的值可以是电容也可以是电感，和天线状态，设计方式，以及天线和USB的布局相对位置有关，具体数值可以通过调试天线本体1的回波损耗RL确定。
天线本体1处于非USB线插入状态时，天线本体1可工作在不同的频段；比如,LTEB5、LTEB2、LTEB12等频段；其中，天线的第一地信号3在每个频段中均具有不同的开关端口接入；比如,工作在LTEB5时第一地信号3与调谐开关电路7的a端口相连，当工作在LTEB12时第一地信号3与b端口相连；相应的，当USB有线插入时，第一地信号3的连接也可以切换至d、e端口。本领域的技术人员可根据本技术方案的上述启示，根据实际调试情况，赋予各个端口相应的值，并选择相应的切换端口。
第二具体实施例：
天线本体1处于非USB插入状态时，天线本体1通过信号线2与主板9上的射频通道相连，第一地信号3通过接线3与调谐开关电路7相连，第二地信号4通过接线6直接与主板9上的地线连接，第一地信号3与第二地信号4均处于工作状态；其中，调谐开关电路7内设置有单刀多掷开关，并将开关打到a端口。
当控制电路8检测到USB有线插入时，调谐开关电路7的开关与a端口断开，与天线本体1的第一地信号3断开连接；第一地信号3处于非工作状态，第二地信号4处于工作状态。基于上述的状态变化，将天线本体1预先调试完成，以实现USB有线插入后天线驻波比产生的偏移修正。
本申请通过上述天线本体与主板之间优化设置有第一连接结构和第二连接结构，能够实现消除因USB有线插入所带来的天线本体驻波比偏移；能够实现天线状态以及性能保持稳定，能够使得天线本体在USB有线插入状态或者USB没有线插入状态下，均能具有较好的辐射效率。
本申请还提供了一种手机，其中，所述可调谐天线采用上述任一方案中的可调谐天线。特别地，所述手机具有多个工作频段，不同的工作频段对应的第一接入状态和/或第二接入状态下所述开关连接的端口可以不同。
本领域的技术人员应该明白，虽然本发明实施例所揭露的实施方式如上，但所述的内容仅为便于理解本发明实施例而采用的实施方式，并非用以限定本发明实施例。任何本发明实施例所属领域内的技术人员，在不脱离本发明实施例所揭露的精神和范围的前提下，可以在实施的形式及细节上进行任何的修改与变化，但本发明实施例的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
工业实用性
通过本发明实施例的方案，天线本体与主板之间设置有第一连接结构和第二连接结构并可以切换，能够实现消除因USB有线插入所带来的天线本体驻波比偏移；能够实现天线状态以及性能保持稳定，能够使得天线本体在USB有线插入状态或者USB没有线插入状态下，均能具有较好的辐射效率。
