背景技术
参照图1所示，当前用于移动终端的天线技术中，常见的有单极天线(monopole)、倒F型天线(IFA，Inverted F-shaped Antenna)、环形天线(LOOP)等，天线馈源常放置于移动终端左侧或者右侧的角落，即为单共振臂天线设计方式。然而单共振臂天线因为天线共振于左侧或右侧的单个分支，导致天线能量过于集中该分支，使得移动终端左右两侧的电场强度差异很大，而且偏向人头手一侧的天线分支的吸收损耗会显著增加，导致人头或者人手的性能出现左右差异很大的问题。
相关技术中，针对传统天线方案提出一种改善方案，该方案中，移动终端的天线具有两个天线分支，分布于上述移动终端两侧，通过开关主动切换使某一天线分支短路，即改变天线末端位置，使得天线能量集中于另一天线分支，来改善左右头手性能。然而，上述改善方案需要基于移动终端的实际使用场景，例如左头手场景或者右头手场景，进行针对性的切换左右天线，也就是说，需要进行使用场景的侦测或者判断，因此存在左右天线切换不灵敏或者适应性差的问题。
发明内容

另一方面，本公开实施例提供了一种天线控制方法，所述天线包括：对称分布的第一天线部分和第二天线部分；所述第一天线部分和所述第二天线部分分别具有多种工作状态，对应多种工作共振频率；则所述方法包括：获取所述第一天线部分的第一工作状态；根据所述第一工作状态，调整所述第二天线部分的第二工作状态，使得所述第一天线部分的工作共振频率和所述第二天线部分的工作共振频率的差值小于设定阈值。
再一方面，本公开实施例还提供了一种移动终端，包括上述任一所述的天线控制系统。
这样，本公开实施例中，通过对称分布的第一天线部分和第二天线部分同时工作，且工作共振频率接近或相等，使得天线能量更均匀地分布于天线两侧，而无需根据移动终端的实际使用场景进行左右天线切换，避免了移动终端天线在改善左右头手性能时左右天线切换不灵敏或者适应性差的问题，达到了平衡天线左右头手功能的技术效果。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
发明人在大量实践中发现，具有相同或者相近工作共振频率的两个天线分支分布于移动终端的左右两侧时，两个天线分支可以有效的分散天线能量，使得左右两侧的电场强度更加均匀，能使得左右人头或人手性能更加均衡，因此本公开实施例的核心构思之一在于，通过对称分布于移动终端左右两侧的第一天线部分和第二天线部分同时工作，且工作共振频率接近或相等，使得天线能量更均匀地分布于上述移动终端左右两侧，而无需根据移动终端的实际使用场景进行左右天线切换。
参照图2所示，示出了本公开实施例的一种天线控制系统的结构示意图，具体可以包括：天线1、控制模块2；上述天线1具体可以包括：对称分布的第一天线部分11和第二天线部分12；上述第一天线部分11和上述第二天线部分12分别具有多种工作状态，对应多种工作共振频率。上述控制模块2具体可以包括：天线工作状态获取子模块21，用于获取上述第一天线部分11的第一工作状态；控制子模块22，用于根据上述第一工作状态，调整上述第二天线部分12的第二工作状态，使得上述第一天线部分11的工作共振频率和上述第二天线部分12的工作共振频率的差值小于设定阈值。
在实际应用中，参照图2所示，上述天线1与馈线3连接，并接收馈线3的射频信号；而且上述第一天线部分11与上述第二天线部分12分别与主板地4连接。一般地，上述馈线3由天线馈源和天线匹配电路串联组成，天线匹配电路用于使天线馈源的射频信号匹配天线的不同工作共振频率。如此，上述馈线3的射频信号可以通过上述第一天线部分11和上述第二天线部分12发射出去；同样地，可以通过上述第一天线部分11和上述第二天线部分 12接收信号。
在应用于移动终端的一种实施例中，上述第一天线部分11和第二天线部分12可以对称分布于移动终端的左右两侧，例如上述第一天线部分11位于上述移动终端左侧，上述第二天线部分12位于上述移动终端的相应对称的右侧；反之亦可。可以理解的是，上述对称并不是指数学意义上的绝对对称，而仅是表示一种相对位置，并不要求严格对称。
上述控制模块2可以分别与上述第一天线部分11、上述第二天线部分12连接或者通过信号连接。上述控制模块2的天线工作状态获取子模块21可以通过信号的传递获取上述第一天线部分11或上述第二天线部分12的工作状态和对应的工作共振频率，例如可以获取工作状态转换时的信号，或者处于工作状态时的信号，或者其他方式。而上述控制子模块22，可以根据上述第一工作状态，调整上述第二天线部分12的第二工作状态，使得上述第一天线部分11的工作共振频率和上述第二天线部分12的工作共振频率的差值小于设定阈值；而上述天线工作状态获取子模块21还可以获取上述第二天线部分12的第二工作状态，如果上述第二工作状态与上述第一工作状态对应，即上述第二天线部分12的当前工作共振频率已经与上述第一天线部分11的当前工作共振频率的差值小于上述设定阈值，则上述控制子模块可以不对上述第二天线部分12进行工作状态的切换。
可以理解的是，上述第一工作状态或第二工作状态的调整可以通过多种方式进行，以改变上述第一天线部分11或上述第二天线部分12的工作共振频率，例如可以通过调节上述第一天线部分11或上述第二天线部分12的天线长度，即分别对应的共振臂的长度的方式来调节对应的工作共振频率；还可以通过调整上述第一天线部分11或上述第二天线部分12与馈线的连接方式，如直接连接或者缝隙耦合连接等；还可以通过调整上述第一天线部分11或上述第二天线部分12与主板地的连接方式，如开路、通路、缝隙耦合、通过不同电路元件连接等各种方式；总之，本公开实施例对此不做限制。
此外，上述第一天线部分11的工作共振频率和上述第二天线部分12的工作共振频率的差值小于设定阈值，这样的限制，是为了使得上述第一天线部分11的工作共振频率和上述第二天线部分12的工作共振频率接近或相等， 这样天线能量的分布就会较为均匀的分布于这两个天线部分，工作共振频率越接近，则分布越均匀。因此，还可以采用其它限制方式，例如，上述第一天线部分11的工作共振频率f1和上述第二天线部分12的工作共振频率f2，满足0.7f1≤f2≤1.3f1，总之，只要是能够使得上述第一天线部分11的工作共振频率和上述第二天线部分12的工作共振频率接近或相等的特征，都在本公开实施例的范围之内。
需要说明的是，上述第一天线部分11或上述第二天线部分12的形状可以灵活多变，可以是单极天线、倒F型天线、环形天线、平面倒F型天线(Planar Inverted F-shaped Antenna，PIFA)等，也可以是G型、F型等多谐振结构。
具体地，在应用于具有第一断口和第二断口的金属框的移动终端中，可以采用上述第一断口和第二断口之间的部分金属框作为上述天线1，上述移动终端的馈线连接于上述部分金属框中段，上述部分金属框与主板地连接；其中，以上述第一断口和上述移动终端的馈线之间的第一部分金属框作为上述第一天线部分11，剩余的上述第二断口和上述移动终端的馈线之间的第二部分金属框作为上述第二天线部分12。类似地，在应用于具有第一金属盖和第二金属盖的移动终端中，可以采用上述第一金属盖作为上述第一天线1，上述移动终端的馈线连接于上述第一金属盖中段，上述第二金属盖与主板地连接，且上述第一金属后盖与上述第二金属后盖之间设置有缝隙；其中，以上述馈线左右两侧的第一金属盖部分分别作为上述第一天线部分11和上述第二天线部分12。上述具体的实施方式仅是为了更详细的描述本公开实施例的技术方案，本公开实施例的实施方式并不限于上述实施方式，对此不加以限制。
综上，在本公开实施例中，通过对称分布的第一天线部分和第二天线部分同时工作，且工作共振频率接近或相等，使得天线能量更均匀地分布于天线两侧，而无需根据移动终端的实际使用场景进行左右天线切换，避免了移动终端天线在改善左右头手性能时左右天线切换不灵敏或者适应性差的问题，达到了平衡天线左右头手功能的技术效果。
参照图3所示，示出了本公开实施例的一种天线控制系统的结构示意图，具体可以包括：天线1、控制模块2。
上述天线1具体可以包括：对称分布的第一天线部分11和第二天线部分12；上述第一天线部分11和上述第二天线部分12分别具有多种工作状态，对应多种工作共振频率；上述第一天线部分11由第一天线111、第一开关112、第一多路调谐电路113串联组成；上述第二天线部分12由第二天线121、第二开关122、第二多路调谐电路123串联组成；上述第一多路调谐电路113和上述第二多路调谐电路123分别由多路调谐支路并列组成。上述第一多路调谐电路113的多路调谐支路与上述第二多路调谐电路123的多路调谐支路之间存在预设对应关系；在上述第一多路调谐电路113的任一调谐支路与上述第一开关112连通，且上述存在预设对应关系的第二多路调谐电路123的调谐支路与上述第二开关122连通时，上述第一天线部分11的工作共振频率和上述第二天线部分12的工作共振频率的差值小于设定阈值。上述控制模块2具体可以包括天线工作状态获取子模块21和控制子模块22。上述天线工作状态获取子模块21具体可以包括：第一标识获取单元211，用于获取上述第一多路调谐电路113中与上述第一开关112连通的调谐支路的第一标识；上述控制子模块22具体可以包括：第二标识获取单元221，用于根据上述第一标识和上述预设对应关系，获得与上述第一标识对应的上述第二多路调谐电路123中调谐支路的第二标识；开关控制单元222，用于控制上述第二开关122连通上述第二多路调谐电路123中上述第二标识对应的调谐支路。
在实际应用中，参照图3所示，上述天线1与馈线3连接，并接收馈线3的射频信号；而且上述第一天线部分11与上述第二天线部分12分别与主板地4连接。一般地，上述馈线3由天线馈源31和天线匹配电路32串联组成，天线匹配电路32用于使天线馈源31的射频信号匹配天线的不同工作共振频率。
参照图3所示，上述第一多路调谐电路113由调谐支路T1、调谐支路T2、调谐支路T3等并列组成；各调谐支路的一端分别接主板地4，另一端悬空或者与第一开关112的切换端连接；同样地，上述第二多路调谐电路123由调谐支路T4、调谐支路T5、调谐支路T6等并列组成；各调谐支路的一端分别接主板地4，另一端悬空或者与第二开关122的切换端连接。
参照图3所示，在本公开实施例中，第一天线111和第二天线121可以 分别看作天线1的对称分布的两个共振臂，但是第一天线部分111的工作共振频率与第一天线111、第一开关112、以及第一多路调谐电路113中与第一开关112连通的调谐支路都是相关的，其中，第一天线111的长度、以及上述第一多路调谐电路113中与第一开关112连通的调谐支路的电学特性，这二者对上述工作共振频率的影响很大，具体的相关性可以通过实验测定或者通过理论估计。而在第一天线111的长度固定的情况下，至少可以调节第一开关111，调节对应的上述第一多路调谐电路113中与第一开关112连通的调谐支路的电学特性，因为不同调谐支路的电学特性不同，例如调谐支路的电学特性可以相当于一个5nH(n为10 -9，H为电感单位)的电感或者相当于1.2pF(p为10 -12，F为电容单位)的电容之类的，相当于调整第一天线部分11的工作状态以及对应的工作共振频率。针对第二天线部分的描述可以参照上述对第一天线部分的描述。
需要说明的是，在上述天线1工作时，第一开关112必然与第一多路调谐电路113中某一路调谐支路连通，且仅与一路调谐支路连通；同样地，第二开关122必然与第二多路调谐电路123中某一路调谐支路连通，且仅与一路调谐支路连通。
而且，上述第一多路调谐电路113的多路调谐支路与上述第二多路调谐电路123的多路调谐支路之间存在预设对应关系；在上述第一多路调谐电路113的任一调谐支路与上述第一开关112连通，且上述存在预设对应关系的第二多路调谐电路123的调谐支路与上述第二开关122连通时，上述第一天线部分11的工作共振频率和上述第二天线部分12的工作共振频率的差值小于设定阈值。那么，在本公开实施例的一种实施方式中，可以通过分别调整上述第一开关112与上述第二开关122的连通状态，即分别与对应的多路调谐电路中某一路调谐支路连通的方式，只要保证上述第一开关112连通的调谐支路与上述第二开关122连通的调谐支路存在预设对应关系，则可以保证上述第一天线部分11的工作共振频率和上述第二天线部分12的工作共振频率的差值小于设定阈值。
上述预设对应关系至少可以通过实验测定来获得。例如，对于已经固定的第一天线部分11，至少第一天线111的长度、以及上述第一多路调谐电路 113的各路调谐支路的电学特性已经固定，那么对于上述各路调谐支路中的调谐支路甲而言，当上述第一开关112连通上述调谐支路甲时，第一天线部分11的工作共振频率是固定的。假设上述第二天线121的长度也已经固定，那么可以通过实验测定，例如第二开关连通第二多路调谐电路123的调谐支路乙，如果此时实验测定的上述第一天线部分11的工作共振频率和上述第二天线部分12的工作共振频率的差值小于设定阈值，则上述第一多路调谐电路113的调谐支路甲与上述第二多路调谐电路123的调谐支路乙存在上述预设对应关系；如果此时实验测定的上述第一天线部分11的工作共振频率和上述第二天线部分12的工作共振频率的差值不小于设定阈值，则逐渐调整调谐支路乙的电学特性，例如增加或减小电容、增加或减小电感等方式，直至实验测定的上述第一天线部分11的工作共振频率和上述第二天线部分12的工作共振频率的差值小于设定阈值，那么此时更新的调谐支路乙作为已经设计好的第二多路调谐电路123的调谐支路，则上述第一多路调谐电路113的调谐支路甲与上述第二多路调谐电路123的调谐支路乙存在上述预设对应关系。那么，如此设计出的第一多路调谐电路113的多路调谐支路与上述第二多路调谐电路123的多路调谐支路之间存在预设对应关系。针对第二天线部分的描述可以参照上述对第一天线部分的描述。
在实际应用中，上述预设对应关系可以归纳为第一开关112连通的调谐支路与第二开关122连通的调谐支路的对应关系，或者第一开关112的连通状态与第二开关122的连通状态，或者其他方式，实际还是对应于连通的调谐支路的对应关系。
在本公开实施例的一种实施方式中，第一天线111的长度为50mm，第一多路调谐电路113由四路调谐支路并列组成，四路调谐支路的电学特性分别为82nH，18nH，5nH，2nH，则第一天线部分11可以共振于LB1(0.7G～0.746GHz)，LB2(0.824G～0.96GHz)，MB(1.71G～2.17GHz)，HB(2.3G～2.69GHz)；第二天线121长度为35mm，第二多路调谐电路123由四路调谐支路并列组成，四路调谐支路的电学特性分别为1.2pf，47nH，6nH，3nH，则可共振于LB1(0.7G～0.746G)，LB2(0.824G～0.96G)，MB(1.71G～2.17G)，HB(2.3G～2.69G)，其中LB1代表低频频段1，LB2代表 低频频段2，MB代表中频频段，HB代表高频频段，G为10 9，Hz为频率单位。其中，上述第一多路调谐电路113的四路调谐支路与上述第二多路调谐电路123的四路调谐支路按上述各自电学特性的顺序一一对应，具有预设对应关系；例如当第一开关112连通第一多路调谐电路113的上述2nH的调谐支路，且第二开关122连通第二多路调谐电路123的上述3nH的调谐支路时，上述第一天线部分11的工作共振频率和上述第二天线部分12的工作共振频率都位于上述HB(2.3G～2.69G)，即上述第一天线部分11的工作共振频率和上述第二天线部分12的工作共振频率接近或相等。上述具体的实施方式仅是为了更详细的描述本公开实施例的技术方案，本公开实施例的实施方式并不限于上述实施方式，对此不加以限制。
在本公开实施例的一种实施方式中，第一开关112与第二开关122可以为单刀多掷开关、单刀单掷开关、电子开关、光电开关或者其它类型；可以采用开合控制、也可以采用开关驱动模块来控制，也可以采用其他形式。
需要说明的是，上述第一标识仅用来标识上述第一多路调谐电路113中与上述第一开关112连通的调谐支路，或者标识上述第一开关112的连通状态。
一般地，在本公开实施例的一种实施方式中，可以通过连接第一开关112的驱动单元，接收上述第一开关112的驱动单元在驱动第一开关112连通某一路调谐支路时发出的连通信号，上述连通信号就可以作为上述第一多路调谐电路113中与上述第一开关112连通的调谐支路的第一标识，因为可以通过上述连通信号获知上述第一开关112连通的是哪一路调谐支路。当然，上述第一标识获取单元211还可以查找默认的第一开关112连通的调谐支路的标识，如果相比于默认连通状态，第一开关112连通的调谐支路进行过改变，那么必然存在对上述第一开关112的驱动，查找储存的最后一次驱动第一开关112连通的调谐支路的标识。针对第二天线部分的描述可以参照上述对第一天线部分的描述。
可以理解的是，上述预设对应关系是预先存储的，可以储存于第二标识获取单元221，也可以存储于其他位置，只要第二标识获取单元221可以获取即可。参照本公开实施例的上一种实施方式，第二标识获取单元221获知 上述连通信号相当于获知上述第一标识，根据预设对应关系，可以直接找到对应上述第一标识的上述第二多路调谐电路123中调谐支路的第二标识，其实相当于获知了第二开关122应该与第二多路调谐电路123中哪一路调谐支路连通；上述开关控制单元222可以根据上述第二标识，发送开关驱动信号给上述第二开关122的驱动单元，通过该驱动单元驱动上述第二开关122与上述第二标识对应的第二多路调谐电路123中的调谐支路连通。
当然，上述第二标识获取单元221还可以查找之前储存的最后一次驱动第二开关122连通的调谐支路的标识或者默认的第二开关122连通的调谐支路的标识，如果该标识与上述第一标识已经存在上述预设对应关系，则上述第二标识获取单元221不改变第二开关122的连通状态。
具体的一种实施方式中，参照图3所示，第一天线111与馈线3连接，且长度为50mm，第一开关112为一单刀三掷开关，第一多路调谐电路113接主板地4，其中，第一多路调谐电路113由调谐支路T1、调谐支路T2、调谐支路T3并列组成，调谐支路T1由82nH的电感元件组成，调谐支路T2由18nH的电感元件组成，调谐支路T3由5nH的电感元件组成；将第一开关112的切换端与调谐支路T1连通，则第一天线部分11工作共振频率位于0.7G～0.746GHz；将第一开关112的切换端与调谐支路T2连通，则第一天线部分11工作共振频率位于0.824G～0.96G Hz；将第一开关112的切换端与调谐支路T3连通，则第一天线部分11工作共振频率位于1.71G～2.17G Hz。
相应地，第二天线121与馈线3连接，且长度为35mm，第二开关122为一单刀三掷开关，第二多路调谐电路123接主板地4，其中，第二多路调谐电路123由调谐支路T4、调谐支路T5、调谐支路T6并列组成，调谐支路T4由6nH的电感元件组成，调谐支路T5由47nH的电感元件组成，调谐支路T6由1.2pf的电容元件组成；将第二开关122的切换端与调谐支路T4连通，则第二天线部分12工作共振频率位于1.71G～2.17G Hz；将第二开关122的切换端与调谐支路T5连通，则第二天线部分12工作共振频率位于0.824G～0.96G Hz；将第二开关122的切换端与调谐支路T6连通，则第二天线部分12工作共振频率位于0.7G～0.746G Hz。
那么，可以理解的是，调谐支路T1与调谐支路T6，调谐支路T2与调谐 支路T5，调谐支路T3与调谐支路T4，分别具有上述预设对应关系。在具体的一种实施方式中，第一标识获取单元211通过连接第一开关112的驱动单元，接收第一开关112的驱动单元在驱动第一开关112连通调谐支路T1时发出的连通信号，获得第一标识T1；第二标识获取单元221，根据预设对应关系，找到对应第一标识T1的第二标识T6；开关控制单元222，发送特定驱动信号给第二开关122的驱动单元，驱动第二开关122与第二标识T6对应的调谐支路T6连通，则此时第一天线部分与第二天线部分的工作共振频率均位于0.7G～0.746G Hz，差值满足设定阈值，天线能量较为均匀的分布于第一天线部分与第二天线部分，则该天线左右头手性能均衡。上述具体的实施方式仅是为了更详细的描述本公开实施例的技术方案，本公开实施例的实施方式并不限于上述实施方式，对此不加以限制。
参照图4所示，示出了本公开实施例中第一天线的调谐示意图。在本公开实施例中，例如第一天线111的长度为50mm，应用于全金属缝隙外观机型，即具有至少两个金属盖板的移动终端机型，两个金属盖板之间设置有缝隙。其中，0.7G、0.96G、1.9G、2.5G单位为Hz，为第一天线部分11的第一开关112分别连通上述第一多路调谐电路113的四路调谐支路时，第一天线部分11的工作共振频率的频段的中心频率，且由左到右，第一个实线曲线表示82nH的调谐支路对应的工作共振频率与驻波比的对应示意图，可见在0.7GHz时，驻波比最小，即此时辐射性能最佳；相应的，由左到右的三个虚线曲线分别对应18nH，5nH，2nH的调谐支路。
参照表1所示，示出了实测的天线暗室有源数据，将传统IFA天线与本公开一些可选的实施例中个双共振臂天线的实施例进行了天线辐射性能比较，采用TRP(Total Radiated Power，总辐射功率)作为性能指标，单位为dbm(分贝毫X，可以表示分贝毫伏，或者分贝毫瓦)，可以对测试天线的整个辐射球面的功率进行面积分，并对整个辐射球面的面积取平均得到，能够反映使用测试天线的移动终端的整机发射功率情况。其中，BHHR(Beside Head and Hand at Right side)表示右人头手模型，即包括有上述天线系统的移动终端在右手持于人头右侧工作时的模型；相应的，BHHL(Beside Head and Hand at Right side)表示左人头手模型，即包括有上述天线系统的移动终端在左手持 于人头左侧工作时的模型；其中，GSM(Global System for Mobile Communication，全球移动通信系统)900、GSM1800、LTE(Long Term Evolution，长期演进)B40、LTE B41为不同制式的不同频段，例如GSM900为GSM制式下的900频段，即上行频率为880-915MHz，下行频率为925MHz-960MHz。显然，从表1可以看出，本公开实施例中的双共振臂天线相比传统IFA天线而言，BHHR和BHHL的总辐射功率的差异明显变小，即左右头手性能更加均衡。

参照图3所示，本公开实施例的一种可选方式中，第一连接点A与上述第一天线111的开路端，即第一天线111远离馈线3的延伸段的末端，的距离小于等于

Figure PCTCN2018081334-appb-000004
则第一天线部分11实际工作共振频率不能达到最大工作共振频率fm1，受限于上述第一连接点A与上述第一天线111的开路端的距离。可以理解的是，上述描述对第二天线部分12同样适用。
本公开实施例的一种可选方式中，上述第一天线111的长度和上述第二 天线121的长度的差值小于设定差值，即上述第一天线111的长度和上述第二天线121的长度差异不能太大，例如二者长度的比值小于2:1且大于1:2。因为如果第一天线111的长度和上述第二天线121的长度差异较大，那么当第一天线部分11的工作共振频率位于高频频段，第二天线部分12的工作共振频率同样位于高频频段时，第一天线部分11的工作共振频率与第二天线部分12的工作共振频率接近，那么天线能量会稍微偏向工作共振频率更高的那一天线部分，但偏向不明显，即左右头手性能较均衡；但是当第一天线部分11的工作共振频率位于低频频段，第二天线部分12的工作共振频率同样位于低频频段时，即使第一天线部分11的工作共振频率与第二天线部分12的工作共振频率接近，那么天线能量会明显偏向工作共振频率更高的那一天线部分，即偏向一侧，使得左右头手性能不均衡，均衡效果差。
