所述曲面透镜12在所述平面124一侧形成有焦点126。可以理解的，所述焦点126是由所述曲面透镜12的形状所确定的客观存在的，但是自由空间中并不存在这样一个可见的点。
所述多个辐射体16包括一个第一辐射体16a，以及除了所述第一辐射体16a之外的第二辐射体16b。其中，所述第一辐射体16a的中心与所述焦点126相对，所述第二辐射体16b沿所述第一辐射体16a的两侧阵列设置。例如，所述第二辐射体16b可以沿所述第一辐射体16a的两侧呈直线阵列设置。
从而，所述第一辐射体16a辐射波束时，所述曲面透镜12和所述超材料透镜14可以将所述第一辐射体16a的辐射波束调节为平行波束；所述第二辐射体16b辐射波束时，所述曲面透镜12和所述超材料透镜14可以对所述第二辐射体16b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。

其中，所述多个辐射体16阵列设置在所述第一金属片182与所述第二金 属片184之间。并且，每一所述辐射体16可以与所述第一金属片182、所述第二金属片184连接。可以理解的，所述多个辐射体16与所述第一金属片182、所述第二金属片184之间为电绝缘的。

此外，所述第一金属片182、所述第二金属片184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182、所述第二金属片184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9，图9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还包括信号源186以及切换开关188。所述信号源186用于产生携带通信数据的电信号。当所述信号源186将产生的电信号输出至所述辐射体16时，所述辐射体16即可辐射波束。其中，可以理解的，所述信号源186可以集成在电路板上，或者所述信号源186可以理解为设置在电路板上的信号处理电路。

可以理解的，所述切换开关188可以包括单刀多掷开关，或者包括多个单刀单掷开关。
所述天线阵列100中，由于曲面透镜12和超材料透镜14可以对辐射体 16的辐射波束形状进行调节，因此可以通过所述切换开关188对所述多个辐射体16的切换来使得天线阵列100实现不同方向的辐射波束扫描。
其中，所述切换开关188可以控制所述信号源186依次接通一个所述辐射体16，以控制所述多个辐射体16依次辐射波束，使得所述天线阵列100实现不同方向的辐射波束扫描。也即，每一时刻所述切换开关188只控制一个辐射体16接通所述信号源186，并控制其它的辐射体16与所述信号源186之间断开，从而可以只控制一个辐射体16辐射波束，并控制其它的辐射体16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，曲面透镜12和超材料透镜14可以对辐射体16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。
