多个所述天线单元711的基板7111可以为一体成型设置，也可以为分体设置，在本发明中，并不做限定。所述微带馈线7113和接地板7115分别腐刻在所述基板711的表面上，均为铜材料制成。
请结合参阅图4，在本实施方式中，所述辐射缝隙7117为矩形状缝隙。所述微带馈线7113包括与所述辐射缝隙7117的长度方向垂直的第一部分701、自所述第一部分701两端分别垂直弯折延伸的第二部分702和第三部分703及自所述第三部分703远离所述第一部分701的一端弯折延伸的第四部分704。所述第一部分701向所述接地板7115的正投影与所述辐射缝隙7117相交，所述第二部分702和所述第三部分703向所述接地板7115的正投影位于所述辐射缝隙7117的两侧且与所述辐射缝隙7117间隔，所述第三部分703的长度大于所述第二部分702，所述第四部分704与所述第一部分701相互平行，且所述第四部分704的长度小于所述第一部分701的长度。
请再次参阅图2，所述金属边框30对应所述辐射缝隙7117的位置处开设有所述辐射窗口80，所述辐射窗口80贯穿所述金属边框30的外侧表面和内侧表面。
优选地，所述辐射窗口80的形状与所述辐射缝隙7115的形状相匹配。在本实施例中，所述辐射缝隙7117的形状为矩形，所述辐射窗口80的形状也为矩形，辐射缝隙7117和辐射窗口80的具体形状本发明并不作限定。
在本实施例中，所述第一长边框、第一短边框、第二长边框、第二短边框均开设有分别与所述辐射缝隙7117位置对应的四个所述辐射窗口80。
参阅图5至图8所示，图5至图8为本发明天线系统的四个毫米波天线阵列在其天线单元相移为0的情况下的方向图。
请参阅图9，图9为本发明天线系统的覆盖效率曲线图，从图9可知，本发明提供的天线系统的总的覆盖效率好。
本发明提供的一种天线系统具有如下有益效果：在金属边框的呈对角设置的两个拐角处分别设置两个相互垂直的毫米波天线阵列，且四个毫米波天线阵列分别贴附于金属边框的内侧表面，并在所述金属边框对应四个所述毫米波天线阵列的位置处均开设有辐射窗口，所有天线的设计均邻近金属边框，节约了移动终端内部空间；所述毫米波天线阵列设计为线性阵列，不仅占用空间小，而且只需要扫描一个角度，设计难度、测试难度和波束管理的复杂度降低，能更灵活地管理天线系统的空间覆盖，实现全频段覆盖，稳定性好；四个毫米波天线阵列密集地分布在移动终端的上端和下端的拐角边框上，减小了射频前端（RFFE）到天线单元的线损，提高了接收效率。采用该天线系统的移动终端通讯信号强且稳定，频段覆盖范围全且收发效率高。
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。
