 本发明的实施方式
下面结合图1至图7对本发明作详细描述。
本发明的第一方面，涉及一种移动终端用相扫阵列天线，该移动终端，例如，可以是手机、电脑或者平板等。如图1至图4所示，所述相扫阵列天线100包括层叠设置的天线层110、第一接地层120、第一传输层130、第二接地层140、第二传输层150和第三接地层160，所述天线层110包括若干天线单元111，所述第一接地层120、所述第一传输层130、所述第二接地层140、所述第二传输层150和所述第三接地层160形成为所述天线层110馈电的非平面巴特勒馈电网络，所述非平面巴特勒馈电网络包括设置于所述第二传输层150的若干输入端Pin和设置于所述第一传输层130的若干输出端Pout，也就是说，输入端Pin与输出端Pout并不位于同一个平面上。每个所述输入端Pin均与每个所述输出端Pout电连接，且任一所述输入端Pin至各个所述输出端Pout的相位差呈等差数值，每一个所述输出端Pout与一个所述天线单元111电耦合。
本实施例中的相扫阵列天线100，其包括由第一接地层120、第一传输层130、第二接地层140、第二传输层150和第三接地层160形成组成的非平面巴特勒馈电网络，并且，该所述非平面巴特勒馈电网络包括设置于所述第二传输层150的若干输入端Pin和设置于所述第一传输层130的若干输出端Pout。每个所述输入端Pin均与每个所述输出端Pout电连接，且任一所述输入端Pin至各个所述输出端Pout的相位差呈等差数值，每一个所述输出端Pout与一个所述天线单元111电耦合，因此，本实施例中的相扫阵列天线100，可以合理的安排阵列馈电端位置，减小传输线带来的部分损耗，同时有效地减小体积，使得相扫阵列天线100的结构更加紧凑。此外，利用非平面巴特勒馈电网络，可以代替传统移相器的使用，降低相扫阵列天线100的制作成本。
如图1至图4所示，所述相扫阵列天线100包括若干个第一通孔170，所述第二传输层150均通过对应的所述第一通孔170与所述第一传输层130电连接。所述相扫阵列天线100还包括若干个第二通孔180，每个所述输出端Pout均通过对应的所述第二通孔180与所述天线单元111电连接。
需要说明的是，对于第一通孔170和第二通孔180的尺寸以及具体形状并没有作出限定，本领域技术人员可以根据实际需要自行定义。例如，第一通孔170和第二通孔180可以均为直通孔的结构，或者，第一通孔170和第二通孔180也可以为锥形孔等等。
如图1、图5和图6所示，所述第一传输层130包括第一条状微带线131，且该第一条状微带线131的两侧设置有连通第一接地层120和所述第二接地层140的第一接地通孔132以形成集成波导，所述第二传输层150包括第二条状微带线151，且该第二条状微带线151的两侧设置有连通所述第二接地层140和所述第三接地层160的第二接地通孔152以形成集成波导。
如图1、图6和图7所示，所述非平面巴特勒馈电网络呈中心对称设置。这样，可以进一步合理的安排阵列馈电端位置，减小传输线带来的部分损耗，同时有效地减小体积。
具体地，如图1、图6和图7所示，所述非平面巴特勒馈电网络包括2*2排布的四个所述输入端Pin（分别为Pin1、Pin2、Pin3和Pin4）以及2*2排布的四个所述输出端Pout（分别为Pout1、Pout2、Pout3和Pout4），所述天线单元111呈2*2阵列排布。当然，根据实际需要，本领域技术人员也可以设计其他数量排布的天线单元111、非平面巴特勒馈电网络，在此并不作限定。在其中一个输入端Pin，例如，输入端Pin1工作时，可以在四个输出端（Pout1、Pout2、Pout3和Pout4）形成（0°、90°、170°、90°）的相位差，可以代替传统移相器的使用，最终共产生四个状态形成相位扫描，降低相扫阵列天线100的制作成本。并且，还可以合理的安排阵列馈电端位置，减小传输线带来的部分损耗，同时有效地减小体积，使得相扫阵列天线100的结构更加紧凑。
如图1、图2和图3所示，所述相扫阵列天线100还包括夹设于所述天线层110、所述第一接地层120、所述第一传输层130、所述第二接地层140、所述第二传输层150和所述第三接地层160中任意相邻两层之间的介质板190。
需要说明的是，对于介质板190的制作材料并没有作出限定，优选地，所述介质板190可以采用FR-4板制作形成。并且，介质板190的介电常数的范围优选地可以为4.2~4.4。所述介质板190的损耗角正切值的取值范围优选地为0.015~0.035。
本发明的第二方面，提供了一种移动终端，所述移动终端采用前文记载的所述的相扫阵列天线100，相扫阵列天线100的具体结构可以参考前文相关记载，在此不作赘述。
本实施例结构的移动终端，具有前文记载的相扫阵列天线100，利用所设置的非平面巴特勒馈电网络，可以代替传统移相器的使用，降低相扫阵列天线100的制作成本。并且，还可以合理的安排阵列馈电端位置，减小传输线带来的部分损耗，同时有效地减小体积，使得相扫阵列天线100的结构更加紧凑。
以上所述的仅是本发明的实施方式，在此应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出改进，但这些均属于本发明的保护范围。
