具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域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，都属于本申请保护的范围。
参考图1和图2，图1为本申请实施例提供的天线阵列的第一种结构示意图，图2为图1所示天线阵列中的透镜和辐射体的示意图。
其中，天线阵列100包括多个透镜12以及多个辐射体14。
所述多个透镜12呈阵列设置。例如，所述多个透镜12可以呈直线阵列设置、矩形阵列设置、圆形阵列设置等等。每一所述透镜12包括相对的第一弧面122以及第二弧面124。所述第一弧面122在所述透镜12的一侧形成凸出部，所述凸 出部使得透镜12在第一弧面122的一侧向外凸出。所述第二弧面124在所述透镜12的另一侧形成凹陷部，所述凹陷部使得所述透镜12在第二弧面124的一侧向内凹陷。
其中，所述第一弧面122可以为椭圆弧曲面，所述第二弧面124可以为圆弧曲面，从而所述透镜12可以形成椭圆弧-圆弧曲面透镜。
可以理解的，所述第一弧面122为椭圆弧曲面时，所述第二弧面124也可以为椭圆弧曲面，从而所述透镜12可以形成双椭圆弧曲面透镜。
其中，所述透镜12可以供电磁波透过，也即可以供无线信号透过。所述透镜12的材质可以为绝缘材料，例如塑胶、玻璃等。
所述多个辐射体14也呈阵列设置。其中，每一所述辐射体14与一个所述透镜12的凹陷部124相对设置。可以理解的，所述辐射体14的数量可以与所述透镜12的数量相等。尽管图1中示出了天线阵列100包括3个透镜12以及3个辐射体14，但图1所示仅仅是一种示例，天线阵列100包括的透镜12和辐射体14的数量还可以为其它数量，例如6个、10个、16个等等。
其中，所述辐射体14用于辐射波束。所述波束可以携带蜂窝网络信号、Wi-Fi信号、GPS信号等无线信号中的一种。所述辐射体14的辐射波束由所述凹陷部124辐射至所述透镜12，并由所述凸出部122辐射至自由空间。其中，自由空间即为所述天线阵列100外部的空间。所述透镜12用于调节所述辐射体14的辐射波束的形状。例如，所述透镜12可以对辐射体14的辐射波束的形状进行汇聚，使辐射波束的辐射方向更为集中，以提高天线阵列100向自由空间辐射的信号的增益。再例如，所述透镜12可以对辐射体14的辐射波束的形状进行发散，使辐射波束的辐射方向覆盖更大的角度，以提高天线阵列100向自由空间辐射的信号的覆盖范围。再例如，所述透镜12可以改变辐射体14的辐射波束的朝向，使辐射波束朝向不同方向进行辐射，以实现天线阵列100对不同辐射方向的扫描。
其中，所述多个辐射体14的辐射波束可以均为水平极化波束或者均为垂直极化波束，从而所述天线阵列100可以实现向自由空间辐射水平极化的无线信号或者垂直极化的无线信号，以提高辐射的无线信号的抗干扰性能。
可以理解的，所述多个辐射体14的辐射波束中，一部分辐射波束可以为水平极化波束，另一部分辐射波束可以为垂直极化波束。也即，至少一个辐射波 束为水平极化波束，至少一个辐射波束为垂直极化波束。从而，天线阵列100可以同时通过水平极化波束和垂直极化波束向自由空间辐射相同频率的无线信号，以提高辐射的无线信号的带宽。
在本申请的描述中，需要理解的是，诸如“第一”、“第二”等术语仅用于区分类似的对象，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。
同时参考图3，图3为本申请实施例提供的天线阵列的第二种结构示意图。
所述多个透镜12中，每一所述透镜12在所述凹陷部124的一侧形成有焦点126。其中，所述多个辐射体14中，至少一个辐射体14的中心与一个所述焦点126重合。从而，中心与所述焦点126重合的辐射体14辐射波束时，与所述辐射体14相对的透镜12可以将所述辐射波束汇聚为平行波束，并向自由空间辐射平行波束。
其中，中心与焦点126重合的辐射体14的数量可以为一个，也可以为多个。例如，如图3所示，所述多个辐射体14中，每一所述辐射体14的中心均与一个所述焦点126重合。从而，每一个所述透镜12都可以将与所述透镜12相对的辐射体14的辐射波束汇聚为平行波束。因此，所述多个辐射体14都辐射波束时，所述天线阵列100可以向自由空间辐射平行波束。
参考图4，图4为本申请实施例提供的天线阵列的第三种结构示意图。
可以理解的，所述多个辐射体14中，至少一个辐射体14的中心与一个所述焦点126重合时，还可以存在至少一个辐射体14的中心相对于一个所述焦点126偏移。其中，所述焦点126为与所述辐射体14相对设置的透镜12的焦点。也即，至少一个辐射体14的中心相对于与所述辐射体14相对设置的透镜12的焦点偏移。
从而，焦点与辐射体14的中心重合的透镜12可以将所述辐射体14的辐射波束调节为平行波束；焦点与辐射体14的中心偏移的透镜12可以对所述辐射体14的辐射波束进行汇聚，但并不会调节为平行波束。因此，所述天线阵列100向自由空间辐射波束时，辐射的波束既包括平行波束，又包括非平行波束，平行波束朝向的辐射方向的无线信号强度更强，非平行波束可以覆盖更大的范围。因此，既可以提高天线阵列100向自由空间辐射波束的信号强度，又可以保证辐射波束覆盖较大的范围。
参考图5，图5为本申请实施例提供的天线阵列的第四种结构示意图。
其中，所述多个透镜12可以沿第一方向呈直线阵列设置。所述第一方向例如可以为水平方向、垂直方向等。在所述第一方向上，处于所述天线阵列100的居中位置的第一透镜12A对应的辐射体14的中心与所述第一透镜12A的焦点126重合；位于所述第一透镜12A两侧的第二透镜12B对应的辐射体14的中心相对于所述第二透镜12B的焦点126偏移。也可以理解为，位于天线阵列100居中位置的辐射体14与第一透镜12A的焦点重合，位于天线阵列100边缘位置的辐射体14相对于第二透镜12B的焦点偏移。
其中，所述第二透镜12B对应的辐射体14的中心位于所述第一透镜12A的焦点与所述第二透镜12B的焦点之间。也可以理解为，所述第二透镜12B对应的辐射体14的中心与所述第一透镜12A的焦点之间的距离小于所述第二透镜12B的焦点与所述第一透镜12A的焦点之间的距离。
其中，所述第二透镜12B对应的辐射体14的中心相对于所述第二透镜12B的焦点的偏移量与所述第二透镜12B距所述天线阵列100的居中位置的距离成正比。也即，所述第二透镜12B距所述天线阵列100的居中位置越远时，所述第二透镜12B对应的辐射体14的中心相对于所述第二透镜12B的焦点的偏移量越大。其中，所述第二透镜12B的焦点与所述第一透镜12A的焦点之间的距离可以记为第一距离，所述第二透镜12B对应的辐射体14的中心与所述第一透镜12A的焦点之间的距离可以记为第二距离，所述偏移量即为所述第一距离与所述第二距离之差。因此，所述第二透镜12B距所述天线阵列100的居中位置越远时，所述第二透镜12B对与所述第二透镜12B对应的辐射体14的辐射波束的汇聚作用越强。
可以理解的，当所述多个透镜12的数量为奇数时，位于直线阵列居中位置的至少一个透镜12为第一透镜12A，位于所述至少一个第一透镜12A两侧的透镜12为第二透镜12B。当所述多个透镜12的数量为偶数时，位于直线阵列居中位置的至少两个透镜12为第一透镜12A，位于所述至少两个第一透镜12A两侧的透镜12为第二透镜12B。
其中，还可以理解的，每一个所述第一透镜12A以及与所述第一透镜12A相对设置的辐射体14可以形成一个正轴型透镜天线102，每一个所述第二透镜12B以及与所述第二透镜12B相对设置的辐射体14可以形成一个偏轴型透镜天 线。
参考图6，图6为本申请实施例提供的天线阵列的左视图。
其中，天线阵列100还包括第一金属片162以及第二金属片164。所述第一金属片162设置在所述多个透镜12上。并且，所述第一金属片162与每一所述透镜12的第一弧面122、第二弧面124连接。所述第二金属片164也设置在所述多个透镜12上。所述第二金属片164与所述第一金属片162相对设置。并且，所述第二金属片164也与每一所述透镜12的第一弧面122、第二弧面124连接。
可以理解的，每一所述透镜12还包括相对的第一侧面123和第二侧面125。所述第一侧面123与所述第一弧面122、所述第二弧面124连接，所述第二侧面125也与所述第一弧面122、所述第二弧面124连接。所述第一侧面123、所述第二侧面125可以都为平面。其中，所述第一金属片162设置在所述多个透镜12的第一侧面123，所述第二金属片164设置在所述多个透镜12的第二侧面125。
也可以理解为，所述多个透镜12阵列设置在所述第一金属片162与所述第二金属片164之间，并且每一所述透镜12均与所述第一金属片162、所述第二金属片164连接。也即，每一所述透镜12的第一侧面123均与所述第一金属片162贴合，每一所述透镜12的第二侧面125均与所述第二金属片164贴合。其中，每一所述透镜12的第一弧面122、第二弧面124可以理解为连接在所述第一金属片162和所述第二金属片164之间的表面，并且每一所述透镜12的第一弧面122、第二弧面124均与所述第一金属片162垂直，以及每一所述透镜12的第一弧面122、第二弧面124均与所述第二金属片164垂直。
其中，所述多个辐射体14阵列设置在所述第一金属片162与所述第二金属片164之间。并且，每一所述辐射体14可以与所述第一金属片162、所述第二金属片164连接。可以理解的，所述多个辐射体14与所述第一金属片162、所述第二金属片164之间为电绝缘的。
可以理解的，所述第一金属片162、所述第二金属片164在所述多个透镜12的第二弧面124所在的一侧凸出于所述多个透镜12，从而形成一容置空间163。所述多个辐射体14阵列设置在所述容置空间163中。
此外，所述第一金属片162、所述第二金属片164相对于所述多个透镜12的第二弧面124凸出的长度大于或等于每一所述透镜12的焦点126与第二弧面124之间的距离。因此，每一所述透镜12的焦点126均位于所述第一金属片162 与所述第二金属片164之间，或者理解为每一所述透镜12的焦点126均位于所述容置空间163中，从而可以便于所述多个辐射体14的设置。
可以理解的，所述第一金属片162、所述第二金属片164可以为所述多个透镜12以及所述多个辐射体14提供支撑作用，便于所述多个透镜12以及所述多个辐射体14的安装和固定。此外，所述第一金属片162、所述第二金属片164可以形成天线阵列100的外部框架，或者理解为所述第一金属片162、所述第二金属片164形成所述天线阵列100的外壳。从而，所述天线阵列100可以形成一个整体的密封结构。
参考图7，图7为本申请实施例提供的天线阵列的第五种结构示意图。
其中，天线阵列100还包括多个控制开关18。每一所述控制开关18与一个所述辐射体14电连接，以控制所述辐射体14辐射波束或停止辐射波束。例如，所述控制开关18可以控制向所述辐射体14施加电信号，以控制所述辐射体14辐射波束；或者控制停止向所述辐射体14施加电信号，以控制所述辐射体14停止辐射波束。其中，可以理解的，所述控制开关18的数量可以与所述辐射体14的数量相等，从而实现每一个控制开关18与一个辐射体14电连接并控制所述辐射体14。
可以理解的，所述多个控制开关18可以集成到处理器上，或者集成到一个单独的处理芯片上。
所述天线阵列100中，由于每一所述透镜12都可以对与所述透镜12相对设置的辐射体14的辐射波束形状进行调节，因此每一所述透镜12可以向自由空间的不同方向辐射波束，从而可以通过所述多个控制开关18控制所述多个辐射体14，使得所述天线阵列100实现不同方向的辐射波束扫描。
其中，所述多个控制开关18可以依次控制一个所述辐射体14辐射波束以及控制其它辐射体14停止辐射波束，以实现所述天线阵列100的扫描。也即，每一时刻所述多个控制开关18只控制一个辐射体14辐射波束，并控制其它的辐射体14停止辐射波束。因此，每一时刻所述天线阵列100只向自由空间的一个方向辐射波束，在不同的时刻可以向不同的方向辐射波束，从而实现不同方向的辐射波束扫描。
本申请实施例提供的天线阵列100中，每一个透镜12可以对与所述透镜12相对设置的辐射体14的辐射波束形状进行调节，从而当所述天线阵列100向自 由空间辐射波束时，可以对辐射波束的辐射方向进行调节，进而可以选择无线信号最强的辐射方向来辐射波束，因此可以提高天线阵列100与其它设备之间通信的灵活性和效率。

    多个阵列设置的辐射体，每一所述辐射体与一个所述透镜的凹陷部相对设置，所述辐射体的辐射波束由所述凹陷部辐射至所述透镜，并由所述凸出部辐射至自由空间，所述透镜用于调节所述辐射体的辐射波束的形状。
  16. 根据权利要求15所述的电子设备，其中，每一所述透镜在所述凹陷部的一侧形成有焦点，所述多个辐射体中，至少一个所述辐射体的中心与一个所述焦点重合。
  17. 根据权利要求16所述的电子设备，其中，每一所述辐射体的中心均与一个所述焦点重合。
  18. 根据权利要求16所述的电子设备，其中，所述多个辐射体中，至少一个所述辐射体的中心相对于一个所述焦点偏移，所述焦点为与所述辐射体相对设置的透镜的焦点。
  19. 根据权利要求18所述的电子设备，其中，所述多个透镜沿第一方向阵列设置，在所述第一方向上，处于所述天线阵列的居中位置的第一透镜对应的辐射体的中心与所述第一透镜的焦点重合，位于所述第一透镜两侧的第二透镜对应的辐射体的中心相对于所述第二透镜的焦点偏移。
  20. 根据权利要求15所述的电子设备，其中，还包括处理器，所述处理器与所述天线阵列电连接，所述处理器用于控制所述天线阵列依次朝向不同方向进行辐射波束扫描，以确定辐射信号最强的辐射方向，并控制所述天线阵列朝向所述辐射信号最强的辐射方向辐射波束。
