Description

天线组件、电子装置及改善天线辐射指标的方法 技术领域
本申请涉及一种电子设备，特别涉及一种具有天线的电子装置、天线组件及应用于所述电子装置的改善天线辐射指标的方法。
背景技术
辐射杂散作为目前电子设备的强制认证指标，是所有天线辐射指标认证当中最复杂，最为难解的一个难题。特别是对于GSM频段，在部分工作场景下，它本身的功率会比较高，很容易在瞬间激发强有的能量从而导致辐射杂散的谐波超标。在实际的使用中，我们也主要会碰到GSM900的三次谐波容易超标，GSM1800的二次或者三次谐波超标。
对于射频信号而言，发射的信号不仅仅会包含可用信号(GSM900)，往往在这其中还会包含有二次(1800GHz)/三次谐波的成分(2700GHz)，实际的使用中大部分是三次谐波会出现超标。同样对于谐振的天线而言，也会包含有基波，二次/三次的谐振。而当射频信号的三次谐波能量到达天线的三次谐振处，就会将这些无用的谐波能量辐射出去，从而导致杂散超标。
另外，GSM作为大功率通信连接制式，在大部分情况下都是使用较小的功率，发射的天线信号通过放大器放大后实现通话，然而，部分场景下GSM也会处于大功率情况，当GSM在处于大功率情况下时，会导致GSM的放大器的线性度急剧下降从来使得谐波的成分会增加，这种携带的谐波成分会随着天线的辐射而导致辐射杂散超标。
发明内容
本申请的目的在于提供一种天线组件、电子装置及改善天线辐射指标的方法，可在天线工作在不同的功率下时，都能有效避免天线的辐射杂散超标而改善天线的辐射指标。

所述天线放大器12及所述耦合器13依次耦接于所述射频收发单元11与所述天线14之间，且所述耦合器13还与所述射频收发单元11耦接。即，所 述天线放大器12耦接于所述射频收发单元11与所述天线14之间，所述耦合器13耦接于所述天线放大器13、所述射频收发单元11及所述天线14之间。

从而，本申请中，通过所述耦合器13将所述天线放大器放大输出的天线信号耦合反馈回射频收发单元11，然后射频收发单元11根据耦合器13反馈回的耦合信号分析得到天线放大器12产生的非线性谐波信号，而产生用于消除所述非线性谐波信号的反向预处理信号，有效地消除了天线放大器12工作在非线性阶段产生的非线性谐波信号，避免了天线14的辐射杂散超标，改善了天线14的辐射指标。

请一并参阅图2，为射频收发单元11的结构框图。如图2所示，所述射频收发单元11包括基带处理器111、解调接收器112、反向器113以及合路器114。
所述基带处理器111用于产生所述天线信号。
所述解调接收器112与所述耦合器13耦接，用于接收所述耦合器13反馈的耦合信号，并对所述耦合信号进行解调而得出对应的非线性谐波信号。在一些实施例中，所述天线放大器12产生的非线性谐波信号已经是经过载波调制后的信号，从而，所述耦合器13反馈给所述解调接收器112的耦合信号也为经过载波调制后的信号。所述解调接收器112先对所述耦合信号进行解调而得到解调后的耦合信号，然后，根据所述解调后的耦合信号以及所述耦合器13的特定耦合系数X1而还原出所述非线性谐波信号。
所述反向器113用于根据所述解调接收器112还原出的非线性谐波信号产生对应的反向预处理信号。具体的，所述反向器113根据所述解调接收器112还原出的非线性谐波信号的振幅和方向而产生振幅与所述非线性谐波信号的振幅相同、方向与所述非线性谐波信号的方向相反的反向预处理信号。
请一并参阅图3，为非线性谐波信号和反向预处理信号的示意图。如图3所示，设非线性谐波信号为S2，反向预处理信号为S3，反向预处理信号S3与所述非线性谐波信号S2的周期相同、振幅相同，且反向预处理信号S3的每个波峰正好对应所述非线性谐波信号S2的每个波谷，反向预处理信号S3的每个波谷正好对应所述非线性谐波信号S2的每个波峰，而形成与所述非线性谐波信号S2的振幅相同、方向相反的信号。其中，图3中，粗线所示的为非线性谐波信号为S2，细线所示的为反向预处理信号为S3。
所述合路器114用于将所述基带处理器111产生的所述天线信号与所述反向器113产生的反向预处理信号进行合成，而形成包括所述反向预处理信号与所述天线信号的合成信号，并发送给所述天线放大器12。
由于所述天线放大器12产生的非线性谐波信号与所述合成信号中的反向预处理信号的振幅相同、方向相反，从而，所述天线放大器12产生的非线性谐波信号被所述合成信号中的反向预处理信号抵消，而使得输出给天线14的天线信号中的非线性谐波信号被消除，避免了天线14的辐射杂散超标。
请一并参阅图4，为本申请一实施例中的天线组件1的示意出了耦合器13的具体结构的示意图。如图4所示，所述耦合器13包括输入端131、第一输出端132以及第二输出端133，所述输入端131与所述天线放大器12耦接，用于接收所述天线放大器12对天线信号放大后输出的放大后的天线信号。所述第一输出端132与所述天线14耦接，所述输入端131与所述第一输出端132可通过导线等直接连接。从而，所述输入端131接收的所述天线放大器12放大后的天线信号通过所述第一输出端132直接输出给天线14，并通过天线14辐射出去。
所述第二输出端132与所述射频收发单元11耦接，进一步的，为与所述射频收发单元11中的解调接收器112耦接。所述耦合器13还包括耦接于所述输入端31以及所述第二输出端133之间的耦合件134，所述耦合件134用于执行前述的耦合器13的功能，即，所述耦合件134对所述输入端131接收的所述天线放大器12放大后的天线信号进行耦合而得到耦合信号，并通过所述第二输出端133输出给所述射频收发单元11的解调接收器112，而将所述耦合信号反馈至所述射频收发单元11。其中，所述耦合件134可为特定的耦合 器件或耦合电路。
从而，本申请中，所述射频收发单元11根据耦合器13的反馈而生成用于抵消天线放大器12产生的非线性谐波信号的反向预处理信号，然后在发送给天线放大器12的天线信号给天线放大器12时，同时发送所述反向预处理信号至所述天线放大器12，有效地抵消了天线放大器12产生的非线性谐波信号，从而避免了辐射杂散超标，有效地改善了辐射杂散这一天线辐射指标。
其中，所述天线放大器12具体可为GSM(全球移动通信系统，Global System forMobile Communications)天线放大器。
