具体实施方式
下面将结合本实施例中的附图，对本实施例中的技术方案进行描述。
本实施例所述的天线装置，应用于双屏终端，如图1所示，所述天线装置包括以下结构。
检测器11，设置为检测所述双屏终端的目标状态，并根据所述双屏终端的目标状态输出目标状态指示信号。
天线匹配电路12，与所述检测器11连接，设置为根据所述目标状态指示信号调节天线匹配阻抗。
第一天线走线13，通过馈电点10与所述天线匹配电路12连接。
天线辅助走线(图1中未示出)；以及，
控制器14，设置为根据所述目标状态指示信号控制所述第一天线走线是否与所述天线辅助走线射频连接。
本实施例所述的天线装置根据双屏终端的目标状态，通过天线匹配电路调节天线匹配阻抗，通过控制器控制第一天线走线与天线辅助走线之间射频连接或不连接，即根据双屏终端的目标状态相应调节天线本体走线的长度，以得到较好的辐射特性。
图1中所示出的第一天线走线13的结构为本实施例提供的一种实施方式。在本实施例中，所述第一天线走线13为主天线走线，设置于双屏终端的第一屏幕(即主屏幕)下端非金属区域，所述第一天线走线13可以采用柔性印刷电路板(Flexible Printed Circuit，FPC)、激光直接成型(Laser-Direct-structuring，LDS)等方式的走线。
可选地，所述目标状态可以包括第一目标状态和第二目标状态。
控制器14在所述双屏终端的目标状态为第一目标状态时控制所述第一天线走线13与所述天线辅助走线射频连接；控制器14在所述双屏终端的目标状态 为第二目标状态时控制所述第一天线走线13与所述天线辅助走线之间不射频连接。
其中，所述第一目标状态可以为展开状态，所述第二目标状态可以为折叠状态。
当双屏终端展开时(即双屏终端包括的第一屏幕和第二屏幕处于展开状态时)，控制器14控制第一天线走线13与天线辅助走线射频连接，使得天线本体走线的长度为第一天线走线13与天线辅助走线的长度之和，以增加天线本体走线的长度，解决相关技术中由于双屏终端展开时天线参考地的对角线长度增加而天线本体走线长度不变，导致的辐射特性差的问题。
在实施时，所述天线匹配电路12设置为根据所述目标状态指示信号调节天线匹配阻抗。
所述天线匹配电路可以包括射频开关模块和天线匹配模块；所述射频开关模块可以包括单刀双掷开关或单刀多掷开关，所述开关匹配模块可以包括两个或多个开关匹配子模块，每一开关匹配子模块对应于一天线匹配阻抗，所述射频开关模块根据所述目标状态指示信号改变开关状态，以获取相应的天线匹配阻抗。例如，当双屏终端展开时，天线匹配电路的射频开关模块根据第一目标状态指示信号改变开关状态，选择一开关匹配子模块，获取与第一目标状态相对应的天线匹配阻抗；当双屏终端折叠时，天线匹配电路的射频开关模块根据第二目标状态指示信号改变开关状态，选择一开关匹配子模块，获取与第二目标状态相对应的天线匹配阻抗。天线匹配电路根据目标状态指示信号调节天线匹配阻抗，可以实现天线和馈线间的匹配，使得天线传输功率更大。
天线谐振频率f与波长λ有如下关系：f＝C/λ，其中C是与介质中的电磁波传播速度和传播电磁波介质本身相关的介电常数，当介质固定时，该介电常数C 也是定值，所以当介质固定时从以上公式可以看出天线谐振频率f同波长λ成反比。
其中，取1/4波长的长度作为天线走线长度时，可以在天线上得到最大峰值电压，有利于最大能量辐射，所以当天线走线长度与辐射波长λ的比例为1/4时，可以获得好的辐射效率。
本实施例提供的天线装置中，双屏终端折叠时，天线主体为第一天线走线；双屏终端展开时，天线主体为第一天线走线和天线辅助走线形成的单极子天线。
本实施例所述的天线装置在双屏终端折叠和展开时通过控制器控制第一天线走线与天线辅助走线之间射频连接或不连接，使得天线本体走线长度改变，因此对应的最佳辐射的波长也应改变，可以通过天线匹配电路12改变天线匹配阻抗来改变天线谐振频率f，即改变波长λ，以获得比较好的辐射效率。
可选地，本实施例所述的天线装置还可以包括：第二天线走线，所述第二天线走线与第一接地点连接。
所述控制器根据所述双屏终端的目标状态指示信号控制第二天线走线是否与所述天线辅助走线射频连接。
可选地，所述控制器在检测到所述双屏终端的目标状态为第一目标状态时控制所述第二天线走线与所述天线辅助走线射频连接，以使得所述第一天线走线、所述第二天线走线和所述天线辅助走线形成环形天线；所述控制器在检测到所述双屏终端的目标状态为第二目标状态时控制所述第二天线走线与所述天线辅助走线不射频连接。
例如，所述第一目标状态可以为展开状态，所述第二目标状态可以为折叠状态。
当所述双屏终端展开时，第一天线走线、第二天线走线和天线辅助走线之 间形成环形天线，以使得双屏终端展开时由第一天线走线、第二天线走线和天线辅助走线之间形成的环形天线基本能覆盖折叠状态时候天线的频带。
在可选情况下，当所述双屏终端的目标状态为第一目标状态(所述第一目标状态例如可以为展开状态)时，所述天线装置的天线主体包括由所述第一天线走线、所述第二天线走线和所述天线辅助走线形成的环形天线，所述环形天线的长度与所述双屏终端处于第一目标状态时的参考地长度之间的差值的绝对值小于第二预定长度差值，也即所述环形天线的长度与所述双屏终端处于第一目标状态时(所述第一目标状态例如可以为展开状态)的参考地长度相匹配，以保证天线的正常辐射。
当所述双屏终端的目标状态为第二目标状态(所述第二目标状态例如可以为折叠状态)时，所述天线装置的天线主体为第一天线走线和第二天线走线，所述第一天线走线和第二天线走线的长度与所述双屏终端的目标状态为第二目标状态(所述第二目标状态例如可以为折叠状态)时的参考地长度之间的差值的绝对值小于第一预定长度差值，也即所述环形天线的长度与所述双屏终端的目标状态为第二目标状态时(所述第二目标状态例如可以为折叠状态)的参考地长度相匹配，以保证天线的正常辐射。
所述第一预定长度差值和所述第二预定长度差值可以根据实际情况确定，一般情况下，第一预定长度差值的取值与所述双屏终端的目标状态为第一目标状态时的参考地长度相比而言小的多，第二预定长度差值的取值与所述双屏终端的目标状态为第二目标状态时的参考地长度相比而言小的多。
可选地，本实施例所述的天线装置还可以包括：第三天线走线，所述第三天线走线与第二接地点连接。
所述第一天线走线和所述第三天线走线之间射频连接。
将第一天线走线和第三天线走线通过射频连接后，天线形式从原来的单极子天线变成了倒F型(Inverted F Antenna，IFA)天线，IFA天线的效率较单极子天线的效率差一些，但是IFA天线的频带会比单极子天线的频带宽，而且由于IFA天线本身是信号和地相连接，所以相对于单极子天线没有和地相连，IFA天线受人手的影响较小，因为人体本身就是和大地相连。
可选地，所述检测器可以包括霍尔器件和驱动模块。
所述双屏终端包括第一屏幕、第二屏幕和转轴转接组件；所述转轴转接组件包括转轴以及用于固定所述转轴的转轴座；所述第一屏幕和所述第二屏幕之间通过所述转轴连接。
所述霍尔器件包括设置于所述转轴上的磁铁和固定于所述转轴座上的霍尔传感器。
所述驱动模块用于接收所述霍尔传感器输出的霍尔电压，并根据所述霍尔电压判断双屏终端折叠或展开，并输出相应的目标状态指示信号。
在实施时，所述驱动模块可以设置于所述双屏终端的电路板上。
可选地，所述磁铁随着所述转轴转动而转动，所述霍尔传感器固定与所述转轴座上，所述驱动模块根据所述霍尔电压判断双屏终端折叠或展开，并输出相应的目标状态指示信号。
下面通过一实施例来说明本公开所述的天线装置。
如图2所示，本实施例所述的天线装置应用于的双屏终端折叠；可选地，所述双屏终端可以为双屏手机。
在图2中，标识为21的为所述双屏终端的第一屏幕，标识为22的为所述双屏终端的上转轴转接组件，标识为23的为所述双屏终端的下转轴转接组件。
如图2所示，本实施例所述的天线装置包括检测器、天线匹配电路12、第 一天线走线13、天线辅助走线(图2中未示出)、控制器、第二天线走线15和第三天线走线16。
所述第一天线走线13通过馈电点10与所述天线匹配电路12连接。
所述第二天线走线15与第一接地点20连接。
所述第三天线走线16与第二接地点30连接。
所述检测器包括设置于所述上转轴转接组件22上的霍尔器件111和设置于所述第一屏幕21上的驱动模块112。
所述霍尔器件111与所述驱动模块112连接。
所述驱动模块112与所述天线匹配电路12连接。
所述控制器包括位于所述下转轴转接组件23上的第一金属弹片31和第二金属弹片32。
当双屏终端折叠时，霍尔器件111没有检测到打开动作，此时驱动模块112不会给天线匹配电路12发送指示信号，所以天线匹配电路12中的射频开关模块状态不变，天线匹配阻抗不会改变，位于第一屏幕21下端区域中的第一天线走线13不与天线辅助走线射频连接。
如图3所示，所述双屏终端展开，标识为24的是第二屏幕，标识为17的为天线辅助走线；天线辅助走线17的第一端与所述第一金属弹片31连接，天线辅助走线17的第二端与所述第二金属弹片32连接。
当用户打开双屏终端，使得双屏终端展开时，此时霍尔器件111检测到打开动作，将相应的电平信息传输到驱动模块112中，驱动模块112内部的驱动芯片进行检测处理，驱动芯片判断双屏终端有打开动作后，输出相应的目标状态指示信息到天线匹配电路12中，以驱动射频开关模块并控制射频开关模块选择相应的天线匹配电路，以获取相应的天线匹配阻抗。
与当双屏终端展开时，第一金属弹片31控制所述天线辅助走线17与所述第一天线走线13射频连接，第二金属弹片32控制所述天线辅助走线17与所述第二天线走线15射频连接，使得第一天线走线13、第二天线走线15和天线辅助走线17形成环形天线，增加了天线走线长度，保证天线的正常辐射。
天线和参考地之间组成了偶极子，偶极子是指相距很近的符号相反的一对电荷或“磁荷”，因为双屏终端展开时，参考地的长度增大，而天线长度应与参考地的长度相接近，所以可以增加天线的长度，以保证天线的正常辐射，即参考地的长度增大意味这天线长度也要增加(双屏终端展开时参考地面积增大即参考地的长度增大)。
例如，假设当双屏终端折叠时，天线走线长度覆盖低频700兆赫兹(MHz)-900MHz，所以天线走线长度可以通过1/4波长(理想真空中的波长)计算出范围是83mm-107mm，这时对应的参考地长度是指双屏终端折叠时整机对角线的长度，因此参考地长度得范围是83mm-107mm，可以比107mm长。
以5寸机型为例，整机宽度一般为66mm，整机长度为120mm左右，计算得出整机对角线长度为137mm(大于107mm)，所以为了使得天线走线长度和整机对角线长度相接近，则加长天线走线长度到130mm附近，以保证辐射效率。天线走线所处介质的介电常数εr都是大于1，电磁波在介质中的波长λε的计算公式：
Figure PCTCN2017115508-appb-000001
其中λε表示电磁波在介质中的波长，λ表示电磁波在真空中的波长，所以在电磁波在介质中的波长λε会被缩短，λε会小于电磁波真空中的波长λ。
当双屏终端展开时，参考地的长度则变为了178mm，所以为了与参考地的长度相匹配，则增加天线走线长度，以保证天线的正常辐射。
