本实施例中，上述金属边框1可以包括第一侧边11、第二侧边12、第三侧边13和第四侧边14，该金属边框1可以是一个首尾相连或者不相连的边框。上述至少两个缝隙15可以开设在金属边框1的一侧，或者也可以在金属边框1相对的两侧上均开设有至少两个缝隙15等等。缝隙15的内部可以是空气，或者也可以是使用非导电材料进行填充等等。
本实施例中，上述缝隙15为“工”字型缝隙，所述“工”字型缝隙包括相互平行的第一子缝隙151和第二子缝隙152，以及与所述第一子缝隙151垂直的第三子缝隙153。为了更好的理解“工”字型缝隙，可以参阅图2，图2为本公开的一些实施例提供的缝隙的结构示意图。如图2所示，上述缝隙15为“工”字型缝隙，且该缝隙15包括相互平行的第一子缝隙151和第二子缝隙152，以及与所述第一子缝隙151垂直的第三子缝隙153。一个“工”字型缝隙就相当于毫米波阵列天线中的一个天线单元，从而多个“工”字型缝隙就可以组成毫米波阵列天线。
本实施例中，上述金属边框1的内侧壁设置有至少两个天线馈电点2，所述至少两个天线馈电点2中不同的天线馈电点2位于不同缝隙15的第三子缝隙153的侧边，从而可以保证金属边框1的一侧至少有两个缝隙15均存在天线馈电点2，从而至少两个缝隙15可以形成毫米波阵列天线。该毫米波阵 列天线的天线馈电点2均位于第三子缝隙153上，从而可以将毫米波信号引至毫米波阵列天线的天线馈电点2处，通过金属边框1进行辐射。除此之外，金属边框1亦可以接收毫米波信号。
本实施例中，金属边框1的一侧开设有至少两个缝隙15，从而这至少两个缝隙15相当于形成毫米波阵列天线，用于辐射毫米波信号。当第三侧边13上开设有至少两个缝隙15时，通信天线可以如图1中的虚线所示，通信天线由第三侧边13、部分第二侧边12和部分第四侧边14组成。并且，由至少两个缝隙15组成的毫米波阵列天线可以在通信天线的辐射体内侧开有微小的缝隙，从而不影响通信天线的电气参数。上述地板3可以是电路板或者金属中壳等等。上述金属边框1与所述终端设备内的地板3电连接，从而可以对金属边框1进行接地。
这样，通过在终端设备的边框的一侧开设有至少两个缝隙15，相当于形成毫米波阵列天线，从而节省了毫米波阵列天线的容置空间，不占用其他天线的天线空间，可以减小终端设备的体积，提高终端设备整体的竞争力。充分利用终端设备的结构作为天线，提升了通讯效果，且不影响终端设备的金属质感。并且可以在终端设备背面被金属桌遮挡，或者用户手握终端设备时，避免毫米波天线性能大幅下降，使用户有更好的体验。
并且，将毫米波阵列天线融入到相关技术中的通信天线中，如2G、3G、4G或者sub 6G，而不影响通信天线的通信质量，不影响终端设备的功能。同时本身毫米波阵列天线可以获得较好的宽频宽度，由于“工”字形缝隙的存在，可以覆盖5G毫米波多个频段，便于全面屏的天线设计。并且通过基于终端设备的金属边框设计，而不影响终端设备的金属质感，并可提升跨国甚至全球漫游时用户的无线体验。
目前的主流毫米波天线设计，往往较难在金属外观的设计下展现较优的天线性能，亦即较难地支持金属外观的设计，而造成品竞争力下降。本实施例的这种设计方式，可以更好地支持金属外观的设计，且可与外观金属作为其他天线的方案进行兼容设计，以提升产品的总体竞争力。在解决了终端设备内需要为毫米波天线设置容置空间，使整个终端设备的体积尺寸比较大的问题的同时，还可以解决终端设备比较难地支持金属外观的设计的问题。
本公开的一些实施例中，上述终端设备可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等等。
可选的，所述第一子缝隙151与所述第二子缝隙152的长度不同。
本实施方式中，上述第一子缝隙151与所述第二子缝隙152的长度不同，从而可以匹配不同频段的毫米波信号。
可选的，所述第一子缝隙151的长度小于所述第二子缝隙152的长度，所述第一子缝隙151的长度根据天线第一工作频段中心频率对应的半波长确定，所述第二子缝隙152的长度根据天线第二工作频段中心频率对应的半波长确定。
本实施方式中，上述第一子缝隙151的长度小于所述第二子缝隙152的长度，所述第一子缝隙151的长度近似为天线工作第一频段中心频率的半波长，所述第二子缝隙152的长度近似为天线工作第二频段中心频率的半波长，从而可以更好的匹配不同频段的毫米波信号进行工作。
可选的，所述至少两个缝隙15中的任意相邻两缝隙15的排布方式相同；
或者，所述至少两个缝隙15中的任意相邻两缝隙15的排布方式不同。
本实施方式中，为了更好的理解上述排布方式相同的设置，可以参阅图3，图3为本公开的一些实施例提供的金属边框一侧边的结构示意图。如图3所示，第三侧边13上存在至少四个缝隙15，且任意相邻两缝隙15的排布方式相同。
本实施方式中，为了更好的理解上述排布方式不同的设置，可以参阅图4至图6，图4至图6均为本公开的一些实施例提供的金属边框一侧边的结构示意图。图4和图5中，相邻的两个缝隙15相当于垂直90度放置，这样可以提升毫米波阵列天线的水平极化和垂直极化分量，以提升毫米波阵列天线的无线连接能力与天线单元(缝隙15)间的隔离度，进一步提升毫米波阵列天线的波束覆盖范围。
图6中，由于第一子缝隙151的长度小于第二子缝隙152的长度，将相邻的缝隙15如图6所示设置，可以缩短缝隙15之间的间隔且提升天线单元 (缝隙15)间的隔离度，从而使得毫米波阵列天线总体占用空间变小及电气性能更好。
可选的，每个缝隙15均相对于所述缝隙15所在的金属边框1倾斜设置，且倾斜角度一致。
本实施方式中，为了更好的理解上述设置方式，可以参阅图7，图7为本公开的一些实施例提供的金属边框一侧边的结构示意图。图7中可以看到，第三侧边13上存在至少四个倾斜的缝隙15。当终端设备平放在桌面时，每个缝隙15的第三子缝隙与水平面之间的夹角可以为45度。当然，除此之外还可以为缝隙15设置一些其他的倾斜角度等等，对此本实施方式不作限定。
本实施方式中，可以缩短缝隙15之间的间隔且提升缝隙15之间的隔离度，从而使得毫米波阵列天线总体占用空间变小及电气性能更好。毫米波阵列天线总体占用空间变小，提升相邻缝隙15之间的隔离度，进而提升阵列天线扫描覆盖范围。
可选的，所述天线馈电点2位于所述第三子缝隙153边缘的中心位置。
本实施方式中，为了更好的理解上述设置方式，可以参阅图8，图8为本公开的一些实施例提供的天线馈电点的设置位置示意图。如图8所示，第三侧边13上存在至少四个缝隙15，每个缝隙均设置有一个天线馈电点2，且天线馈电点2位于第三子缝隙边缘的中心位置，从而可以使毫米波阵列天线具有更好的性能。
可选的，所述至少两个缝隙15沿所述金属边框1的长度方向排布。
本实施方式中，上述至少两个缝隙15可以组成一个缝隙族，缝隙族中包含至少两个缝隙15。并且，金属边框上还可以存在至少两个缝隙族，例如第一缝隙族和第二缝隙族。第一缝隙族和第二缝隙族分别包括至少两个缝隙，并且第一缝隙族可以位于第二侧边12，第二缝隙族可以位于第四侧边14。这样，通过在不同侧边设置有缝隙族，可以进一步提升毫米波阵列天线的波束覆盖范围。
请参阅图9，图9为本公开的一些实施例提供的缝隙族阵列天线的参数示意图。图9中表示了多个缝隙15的回波损耗。每一个缝隙能够覆盖24-44GHz带宽，即多个5G毫米波频段。馈电信号的接入能够激励第一子缝 隙151和第二子缝隙152，形成毫米波阵列天线的第一谐振M和第二谐振N。
可选的，所述终端设备内还设有信号反射壁4，所述信号反射壁4与所述至少两个缝隙15之间存在间隔，所述信号反射壁4与所述地板3电连接。
本实施方式中，上述信号反射壁4与所述至少两个缝隙15之间存在间隔，该间隔内可以是空气，或者也可以是由一些非导电材料进行填充等等。上述信号反射壁4与所述地板3电连接，从而可以使信号反射壁4接地。由于信号反射壁4的存在，可以优化毫米波阵列天线的增益方向图，提升毫米波阵列天线的主波束覆盖，进而提升毫米波阵列天线的通信效果。
可选的，所述信号反射壁4的上边缘不低于所述缝隙15的上边缘，所述信号反射壁4的下边缘不高于所述缝隙15的下边缘。
本实施方式中，上述信号反射壁4的上边缘不低于所述缝隙15的上边缘，所述信号反射壁4的下边缘不高于所述缝隙15的下边缘，从而信号反射壁4可以很好的覆盖这些缝隙15，便于更好的对信号进行反射。
为了更好的理解上述设置方式，可以参阅图10和图11。图10为本公开的一些实施例提供的金属边框一侧边的结构示意图，图11为本公开的一些实施例提供的信号反射壁与金属边框一侧边的相对位置示意图。
图10中可以看到，金属边框1的第四侧边14上存在至少四个缝隙15，每个缝隙15的第一子缝隙151的长度为L1，第二子缝隙152的长度为L2，第三子缝隙153的长度为L3。L1近似为毫米波天线工作的第一频段的中心频率的所对应的波长的一半，L2近似为毫米波天线工作的第二频段的中心频率的所对应的波长的一半，子缝隙的宽度不作限制，L1<L2。相邻缝隙15的第一子缝隙151之间的间隔为W1，相邻缝隙15的第二子缝隙152之间的间隔为W2，间隔W2由相邻的两缝隙15的隔离度和毫米波阵列天线的最大扫描角度来决定。多个缝隙15的第一子缝隙151、第二子缝隙152和第三子缝隙153组成缝隙族。
图10中，缝隙15上边缘与下边缘之间的距离为H1，多个缝隙15组成的缝隙族的长度为L4。图11中，信号反射壁4上边缘与下边缘之间的距离为H2，信号反射壁4的长度为L5，信号反射壁4与该缝隙族在地板3的同一侧，且H2≥H1。这样，信号反射壁4的上边缘不低于所述缝隙15的上边 缘，所述信号反射壁4的下边缘不高于所述缝隙15的下边缘。从而，可以很好的覆盖这些缝隙15，便于更好的对信号进行反射。当然，为了更好的覆盖这些缝隙15，可选的可以设置L5≥L4，从而可以使缝隙族不超出信号反射壁4长度的范围。
可选的，所述信号反射壁4由所述终端设备的电池的金属外壁形成；或者，所述信号反射壁4由所述终端设备的电池仓的金属壁形成，其中，所述电池仓为容纳所述终端设备的电池的结构。
本实施方式中，上述信号反射壁4由所述终端设备的电池的金属外壁形成；或者，所述信号反射壁4由所述终端设备的电池仓的金属壁形成，从而不需要增加额外的材料，节省终端设备的成本。并且可以优化毫米波阵列天线的增益方向图，提升毫米波阵列天线的主波束覆盖，进而提升毫米波阵列天线的通信效果。
为了更好的理解上述设置方式，可以参阅图12和图13，阅图12和图13均为本公开的一些实施例提供的终端设备的结构示意图。图12中的信号反射壁4为终端设备的电池的金属外壁形成，信号反射壁4与第四侧边14之间的距离为W3，W3>0。图13中的信号反射壁4为终端设备的电池仓的金属壁形成，信号反射壁4与第四侧边14之间的距离为W4，W4>0。
可选的，所述信号反射壁4为内凹的反射曲面；或者，所述信号反射壁4为外凸的反射曲面。
本实施方式中，上述信号反射壁4为内凹的反射曲面；或者，所述信号反射壁4为外凸的反射曲面，可以优化毫米波阵列天线的增益方向图。
