具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通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，都属于本发明保护的范围。
参见图1，图1是本发明实施例提供的天线的结构示意图，如图1所示，包括金属凹槽；四个金属片1，所述四个金属片1间隔设于金属凹槽，且与所述金属凹槽的槽底电连接；耦合金属片2，所述耦合金属片2设于所述四个金属片1之间，且与所述四个金属片1馈电耦合。
本实施例中，上述金属凹槽可以是正方形的凹槽，上述天线可以设置在电子设备上，若电子设备的金属框体有弧度，四个金属片1可以与金属框体弧度共形设计。四个金属片1可以对称放置在金属凹槽的居中位置，即四个金属片1的每个金属片与金属凹槽距离最近的相邻侧边与金属凹槽的距离相等。耦合金属片2可以放置在凹槽的正中位置，耦合金属片2四个端部可以与馈电探针(即导电件)直接相连，馈电探针连接到信号源。
为了更好的理解上述天线的结构，请在参阅图2至图4，图2至图4均为本发明实施例提供的天线的结构示意图。首先如图2所示，此时天线上设置有4个天线单元。每个金属凹槽内设置有四个金属片1和1个耦合金属片2，金属凹槽被绝缘介质3填充。
请参阅图3和图4，图3可以理解为图1的立体图，图4可以理解为图2的立体图，通过图3和图4可以更好的理解上述结构。
请再参阅图5，图5为本发明实施例提供的天线的结构示意图。金属凹槽的底部开设有四个圆孔4，四个馈电探针5可以分别穿过四个圆孔4与耦合金属片2连接。
请再参阅图6，图6为本发明实施例天线提供的反射系数图。如图6所示，-10dB带宽可以覆盖24GHz-44GHz，相对带宽达到58.8％，可以覆盖全球主流的5G毫米波频段，从而提升漫游的体验。
本实施例中，上述天线可以设置在电子设备上。请参阅图7至图9，图7至图9均为本发明实施例提供的电子设备的结构示意图。
首先如图7所示，电子设备的金属框体6上可以有多个断缝，例如可以有四个断缝，其断缝的数量和位置可以根据实际情况如天线数量和频段要求做调整，对此本发明实施例不作限定。这四个断缝可以把金属框体6分为四个部分，即第一侧边61、第二侧边62、第三侧边63和第四侧边64。在这些侧边上可以设计非毫米波天线，例如用第一侧边61可以设计2G/3G/LTE/5G/GNSS/WIFI等非毫米波天线。本实施例也可以在第一侧边61上设置毫米波天线(虚线方框位置)，即毫米波天线集成在非毫米波天线内，从而节省了空间，提升了产品的竞争力。
再如图8和图9所示，虚线框的位置表示设置有天线阵列，从而金属框 体上设置有至少两个天线阵列。当然这些天线阵列的位置可以根据实际的情况进行调整，对此本实施例不作限定。在电子设备金属边框的其它位置设计毫米波阵列天线，使得各部分的毫米波阵列天线协同工作，可以降低手持状态对毫米波阵列天线性能的影响，提升毫米波天线的覆盖范围，如CDF指标。
本实施例中，在天线的金属凹槽中设计毫米波阵列天线，毫米波阵列天线的周围除了辐射方向均有屏蔽功能，从而免受周围环境或金属器件的干扰，而且辐射方向上无其它的介质，使得毫米波阵列天线的性能大幅提升，包括波束扫描的性能也大幅提升，从而提升用户的无线通信体验。并可以基于电子设备的金属边框设计，而不影响电子设备的金属质感，提升全球漫游时用户的多个毫米波频段的无线体验，使用金属边框本身作为天线的反射器，以获得较高增益。
可选的，所述耦合金属片2接入两对差分信号。
该实施方式中，上述耦合金属片2接入两对差分信号，便于差分馈电。
可选的，所述四个金属片1均包括与所述槽底不相交的水平金属片11和与所述槽底电连接的垂直金属片12，所述水平金属片11与所述垂直金属片12垂直连接。
为了更好的理解上述结构，请参阅图10和图11，图10和图11均为本发明实施例提供的天线的结构示意图。如图10和图11所示，所述四个金属片1均包括与所述槽底不相交的水平金属片11和与所述槽底电连接的垂直金属片12，所述水平金属片11与所述垂直金属片12连接。由于上述水平金属片11与垂直金属片12连接，从而便于四个金属片1与耦合金属片2进行耦合。
可选的，所述金属凹槽、所述四个金属片1和所述耦合金属片2之间通过绝缘介质3填充。绝缘介质为非金属介质。通过非金属介质填充金属凹槽，金属片和耦合金属片均可以固定在金属凹槽内。
该实施方式中，所述金属凹槽、所述四个金属片1和所述耦合金属片2之间通过绝缘介质3填充，从而可以对四个金属片1和耦合金属片2起到保护及固定的作用，并且可以保持较好的外观。
可选的，所述耦合金属片2包括呈十字形的第一部分和四个第二部分，每个第二部分呈矩形结构，所述第一部分与所述槽底平行，所述第二部分与 所述槽底垂直，所述四个第二部分分别连接所述第一部分的四个自由端，且向所述槽底延伸。每个第二部分均与槽底绝缘。
为了更好的理解上述结构，请参阅图12，图12为本发明实施例提供的耦合金属片的结构示意图。如图12所示，所述耦合金属片2包括呈十字形的第一部分和四个第二部分，每个第二部分呈矩形结构，所述第一部分与所述槽底平行，所述第二部分与所述槽底垂直，所述四个第二部分分别连接所述第一部分的四个自由端，且向所述槽底延伸。每个第二部分呈矩形结构，上述第一部分与上述金属凹槽的槽底平行，上述第二部分与上述金属凹槽的槽底垂直。
可选的，每个第二部分靠近所述槽底的一侧设置有馈电点，相对的两个馈电点中不同馈电点接收的馈电信号大小相等且相位相反。
为了更好的理解上述结构，亦可以参阅图10进行理解。馈电探针51可以是探针V-，馈电探针52可以是探针H+，馈电探针53可以是探针V+，馈电探针54可以是探针H-。
如图10所示，探针V-和探针V+可以为金属圆柱，连接到信号源给本实施方式的天线单元差分馈电，即连接到探针V-和探针V+的信号幅度相等，相位相差180°。由于采用差分馈电，可以提升共模抑制的能力，抗干扰的能力，且可以提升差分的端到端的隔离度以及提升极化的纯度。同理，探针H-和探针H+也连接到差分馈源，当探针V-和探针V+连接的信号源同时工作，可以激励垂直极化的辐射波，当探针H-和探针H+同时工作时，可以激励水平极化的辐射波，可以达到双极化的辐射，从而减小断线的几率，提升无线通信的稳定性和信号质量，进而提升用户的无线通信体验。
进一步地，当探针V-和探针V+与探针H-和探针H+连接的信号源同时工作时，可形成MIMO，可以提升数据的传输速率。馈电探针从金属腔体的所挖的孔洞穿过，使得馈电探针与金属腔体的金属绝缘，孔洞里可以填充绝缘介质材料，馈电探针连接到信号源。
一般来讲，十字形的耦合金属片比水平的金属片矮，耦合金属片与垂直金属片有空隙，信号源的信号通过耦合金属片的垂直部分(上述第二部分)传递到水平部分，由水平部分耦合能量到水平金属片和垂直金属片，由于该 天线单元结构为对称的结构，构成自补天线，从而使得天线的阻抗在很宽的频率范围内变化很小，从而天线的带宽很宽。
该实施方式中，引入一种新的对称的自补天线结构，可以使得天线的带宽大幅增加，-10dB带宽可以覆盖从24GHz-44GHz，相对带宽达到58.8％，可以覆盖全球主流的5G毫米波频段。并使用差分馈电方式，可以提升共模抑制的能力，抗干扰的能力，且可以提升差分的端到端的隔离度以及提升极化的纯度。对同一个天线单元使用两对差分正交馈电方式，实现了双极化的设计，一可形成MIMO功能，以提升数据的传输速率，二可构成双极化，可以增加天线的无线连接能力，减少通信断线的机率，提升通信效果和用户体验。

本发明实施例还提供一种电子设备，包括上述天线。
本实施例中，上述电子设备可以应用于无线城际网路、无线广域网路、 无线区域网路、无线个人网路、多输入多输出、射频识别，甚至是近场通信、无线充电或FM等无线通信设计与使用上，亦可以应用于对人体安全、健康与佩戴的电子器件(如助听器或心率调整器等)相容性的法规测试与实际设计与使用上。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
上面结合附图对本发明的实施例进行了描述，但是本发明并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本发明的启示下，在不脱离本发明宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本发明的保护之内。
