背景技术
随着第五代移动通信(5-Generation，5G)系统的发展，以及终端设备的广泛应用，毫米波天线逐渐被应用在各种终端设备中，以满足用户日益增长的使用需求。
目前，终端设备中的毫米波天线主要通过天线封装(antenna in package，AIP)技术实现。例如，如图1所示，可以通过AIP技术，将工作波长为毫米波的阵列天线11、射频集成电路(radio frequency integrated circuit，RFIC)12、电源管理集成电路(power management integrated circuit，PMIC)13和连接器14封装成一个模块10，该模块10可以称为毫米波天线模组。其中，上述阵列天线中的天线可以为贴片天线、八木-宇田天线，或者偶极子天线等。
然而，由于上述阵列天线中的天线通常为窄带天线(例如上述列举的贴片天线等)，因此每个天线的覆盖频段有限，但是在5G系统中规划的毫米波频段通常比较多，例如以28GHz为主的n257(26.5-29.5GHz)频段和以39GHz为主的n260(37.0-40.0GHz)频段等，因此传统的毫米波天线模组可能无法覆盖5G系统中规划的主流的毫米波频段，从而导致终端设备的天线性能较差。
发明内容

为了解决上述技术问题，本公开实施例是这样实现的：

第二方面，本公开实施例提供了一种终端设备，该终端设备包括上述第一方面中的天线单元。
在本公开实施例中，天线单元可以包括目标金属凹槽，设置在目标金属凹槽底部M个馈电部，设置在目标金属凹槽内的M个馈电臂和第一绝缘体，以及该第一绝缘体承载的目标辐射体；其中，该M个馈电部中的每个馈电部分别与一个馈电臂电连接，且M个馈电部与目标金属凹槽绝缘，该M个馈电臂位于目标金属凹槽底部和第一绝缘体之间，且该M个馈电臂沿目标金属凹槽的对角线方向分布，以及该M个馈电臂中的每个馈电臂均与目标辐射体和目标金属凹槽耦合，目标辐射体的谐振频率与目标金属凹槽的谐振频率不同，M为正整数。通过该方案，一方面，由于馈电臂与目标辐射体和目标金属凹槽均耦合，因此在馈电臂接收到交流信号的情况下，馈电臂上可以与目标辐射体和目标金属凹槽进行耦合，从而可以使得目标辐射体和目标金属凹槽产生感应的交流信号，进而可以使得馈电臂、目标辐射体和目标金属凹槽产生一定频率的电磁波；并且，由于目标辐射体和目标金属凹槽产生感应电流的位置不同(电流流过的路径不同)，因此馈电臂上的电流经由目标辐射体和目标金属凹槽产生的电磁波的频率也不同，如此可以使得天线单元覆盖不同的频段，即可以增加天线单元覆盖的频段。另一方面，由于M个馈电臂位于目标金属凹槽底部与第一绝缘体之间，且M个馈电臂沿目标金属凹槽的对角线方向分布，因此可以在满足天线单元的性能的前提下，可以适当缩小天线单元的体积，从而可以使得天线单元的结构更加紧凑。如此，由于可以增加天线单元覆盖的频段，并且可以提高天线单元结构的紧凑程度，因此可以提高天线单元的性能。

本公开实施例提供的天线单元可以应用于终端设备，也可以应用于需要使用该天线单元的其它电子设备，具体可以根据实际使用需求确定，本公开实施例不作限定。下面以天线单元应用于终端设备为例，对本公开实施例提供的天线单元进行示例性的说明。
下面结合各个附图对本公开实施例提供的天线单元进行示例性的说明。
如图2所示，天线单元20可以包括目标金属凹槽201，设置在目标金属凹槽201底部M个馈电部202，设置在目标金属凹槽201内的M个馈电臂203和第一绝缘体(图2中未示出)，以及第一绝缘体承载的目标辐射体204。
其中，上述M个馈电部中的每个馈电部202可以分别与一个馈电臂203电连接，且M个馈电部202可以与目标金属凹槽201绝缘，M个馈电臂203可以位于目标金属凹槽201底部和第一绝缘体之间，且M个馈电臂可以沿目标金属凹槽201的对角线L1方向分布，以及M个馈电臂中的每个馈电臂203均可以与目标辐射体204和目标金属凹槽201耦合，目标辐射体204的谐振频率与目标金属凹槽201的谐振频率不同，M为正整数。
可以理解，上述目标金属凹槽也可以作为本公开实施例提供的天线单元中的一个辐射体。
本公开实施例中，上述M个馈电臂与目标金属凹槽耦合具体可以为：M个馈电臂与目标金属凹槽底部耦合。
需要说明的是，本公开实施例中，为了更加清楚地示意天线单元的结构，图2是以本公开实施例提供的天线单元的局部剖面图示意的。其中，图2是以去除第一绝缘体的方式，展示上述M个馈电臂和目标辐射体的(即图2中未示出第一绝缘体)。实际实现时，第一绝缘体是设置在目标金属凹槽内的，且上述目标辐射体可以承载在第一绝缘体上，以及馈电臂位于第一绝缘体和目标金属凹槽之间，即目标金属凹槽、馈电臂、馈电部、第一绝缘体，以及承载在第一绝缘体上的目标辐射体形成一个整体，组成本公开实施例提供的天线单元。
另外，由于馈电部设置在第一金属凹槽底部，因此为了清楚的示意天线单元中各个部件的关系，上述图2中的馈电部202是以虚线示意的。
可选的，本公开实施例中，上述目标金属凹槽的对角线可以为目标金属凹槽的、与目标金属凹槽的开口所在表面平行的截面的对角线。
为了更加清楚地描述本公开实施例提供的天线单元及其工作原理，下面具体以一个天线单元为例，对本公开实施例提供的天线单元发送信号和接收信号的工作原理进行示例性的说明。
示例性的，结合上述图2，本公开实施例中，当终端设备发送5G毫米波信号时，终端设备中的信号源会发出交流信号，该交流信号可以通过馈电部传输到馈电臂。然后，在馈 电臂接收到该交流信号之后，一方面，馈电臂可以与目标辐射体进行耦合，使得该目标辐射体上产生感应的交流信号，然后，目标辐射体可以向外辐射一定频率的电磁波；另一方面，馈电臂还可以与目标金属凹槽耦合，使得目标金属凹槽产生感应的交流信号，然后，目标金属凹槽可以向外辐射一定频率的电磁波(由于目标辐射体和目标金属凹槽产生感应的交流信号的位置不同(即交流信号流过的路径不同)，因此馈电臂上的交流信号经由目标辐射体和目标金属凹槽产生的电磁波的频率也不同)。如此，终端设备可以通过本公开实施例提供的天线单元发送信号。
又示例性的，本公开实施例中，当终端设备接收5G毫米波信号时，终端设备所处的空间中的电磁波可以激励上述目标辐射体和目标金属凹槽，使得该目标辐射体和目标金属凹槽产生感应的交流信号。在该目标辐射体和目标金属凹槽产生感应的交流信号之后，该目标辐射体和目标金属凹槽可以分别与馈电臂进行耦合，使得馈电臂产生感应的交流信号。然后，馈电臂可以通过馈电部向终端设备中的接收机输入该交流信号，如此可以使得终端设备接收到其它设备发送的5G毫米波信号。即终端设备可以通过本公开实施例提供的天线单元接收信号。
本公开实施例提供一种天线单元，一方面，由于馈电臂与目标辐射体和目标金属凹槽均耦合，因此在馈电臂接收到交流信号的情况下，馈电臂上可以与目标辐射体和目标金属凹槽进行耦合，从而可以使得目标辐射体和目标金属凹槽产生感应的交流信号，进而可以使得馈电臂、目标辐射体和目标金属凹槽产生一定频率的电磁波；并且，由于目标辐射体和目标金属凹槽产生感应电流的位置不同(电流流过的路径不同)，因此馈电臂上的电流经由目标辐射体和目标金属凹槽产生的电磁波的频率也不同，如此可以使得天线单元覆盖不同的频段，即可以增加天线单元覆盖的频段。另一方面，由于M个馈电臂位于目标金属凹槽底部与第一绝缘体之间，且M个馈电臂沿目标金属凹槽的对角线方向分布，因此可以在满足天线单元的性能的前提下，可以适当缩小天线单元的体积，从而可以使得天线单元的结构更加紧凑。如此，由于可以增加天线单元覆盖的频段，并且可以提高天线单元结构的紧凑程度，因此可以提高天线单元的性能。
可选的，本公开实施例中，结合图2，如图3所示，目标金属凹槽可以包括第一金属凹槽201a和设置在第一金属凹槽201a底部的第二金属凹槽201b。
其中，第一金属凹槽201a的第一侧壁S1与第二金属凹槽201b的第二侧壁S2不平行，M个馈电部202设置在第一金属凹槽201a底部，M个馈电臂203和第一绝缘体设置在第一金属凹槽201a内，M个馈电臂中的每个馈电臂203均与目标辐射体204和第二金属凹槽201b耦合。
本公开实施例中，上述第一金属凹槽的第一侧壁与第二金属凹槽的第二侧壁不平行，可以理解为：第二金属凹槽相对于第一金属凹槽旋转了预设角度，其中，第一侧壁与第二侧壁之间的夹角可以为该预设角度。
可选的，本公开实施例中，第一种可能的实现方式：上述第一侧壁可以为第一金属凹槽中的任意一个侧壁，上述第二侧壁可以为第二金属凹槽中的任意一个侧壁。第二种可能的实现方式：上述第一侧壁和第二侧壁可以为第一金属凹槽和第二金属凹槽中位于同一方向上的两个侧壁。具体可以根据实际使用需求确定，本公开实施例不作限定。
本公开实施例中，上述预设角度可以根据本公开实施例提供的天线单元的性能确定。
可选的，本公开实施例中，上述预设角度可以大于0度。具体可以根据实际使用需求确定，本公开实施例不作限定。
可选的，本公开实施例中，当上述第一金属凹槽与上述第二金属凹槽均为矩形凹槽时，上述预设角度可以大于0度，且小于或等于45度。
需要说明的是，本公开实施例中，当上述预设角度大于45度，且小于或等于90度时，上述第一侧壁与上述第二侧壁的位置关系与该预设角度大于0度，且小于或等于45度时上述第一侧壁与第二侧壁的位置关系相同。相应的，当上述预设角度大于90度，且小于或等于135度；或者预设角度大于135度，且小于或等于180度；或者预设角度大于180度，且小于或等于225度；或者预设角度大于225度，且小于或等于270度；或者预设角度大于270度，且小于或等于315度；又或者预设角度大于315度，且小于或等于360度时，上述第一侧壁与上述第二侧壁的位置关系均与预设角度大于0度，且小于或等于45度时上述第一侧壁与第二侧壁的位置关系相同。
示例性的，如图3所示，第一金属凹槽201a的第一侧壁S1与第二金属凹槽201b的第二侧壁S2的夹角为45度，即第二金属凹槽201b相对于第一金属凹槽201a旋转了45度。
本公开实施例中，通过将上述目标金属凹槽设置为两个金属凹槽，即上述第一金属凹槽和第二金属凹槽，并将上述M个馈电部设置在第一金属凹槽底部，以及将第一绝缘体和M个馈电臂设置在第一金属凹槽内，且M个馈电臂与第二金属凹槽耦合，可以使得这两个金属凹槽在天线单元中执行不同的功能，从而可以减小天线单元中的各个部件之间的干扰，例如可以减小在第二金属凹槽与M个馈电臂耦合过程中，设置在第一金属凹槽内的部件造成的干扰。
可选的，本公开实施例中，上述第一金属凹槽和第二金属凹槽均可以为矩形凹槽。
具体的，该第一金属凹槽和第二金属凹槽均可以为正方形凹槽。
可选的，本公开实施例中，第一金属凹槽的开口的形状可以与第二金属凹槽的开口的形状相同，也可以与第二金属凹槽的开口的形状不同。具体可以根据实际使用需求确定，本公开实施例不作限定。
示例性的，第一金属凹槽的开口形状可以为正方形，第二金属凹槽的开口形状也可以为正方形。
当然，实际实现时，上述第一金属凹槽的开口形状和第二金属凹槽的开口形状还可以为任意可能的形状，可以根据实际使用需求确定，本公开实施例不作限定。
本公开实施例中，由于目标辐射体与第二金属凹槽产生的电磁波的最大辐射方向均为第一金属凹槽的开口方向，因此当第一金属凹槽和第二金属凹槽为同一形状的凹槽时，可以使得目标辐射体与第二金属凹槽向外辐射电磁波的波束形状相同，如此可以便于进行波束赋形，从而可以便于控制终端设备的天线性能。
可选的，本公开实施例中，第一金属凹槽的开口可以大于第二金属凹槽的开口。即第一金属凹槽的开口面积可以大于第二金属凹槽的开口面积。
本公开实施例中，由于第二金属凹槽是在第一金属凹槽底部设置的，且第一金属凹槽的开口面积与第一金属凹槽底部面积相等，因此第一金属凹槽的开口大于第二金属凹槽的开口，可以使得第二金属凹槽不被第一金属凹槽遮挡。
当然，实际实现时，第一金属凹槽的开口还可以小于或等于第二金属凹槽的开口，具体可以根据实际使用需求确定，本公开实施例中不作限定。
本公开实施例中，由于第二金属凹槽设置在第一金属凹槽底部，且第一金属凹槽的开口大于第二金属凹槽的开口，因此可以简化天线单元的制造工艺。
可选的，本公开实施例中，上述M个馈电部可以设置在第一金属凹槽201a底部、且贯穿第一金属凹槽201a底部。
需要说明的是，实际实现时，如图3所示，本公开实施例中，馈电部202的第一端可以与馈电臂203电连接，馈电部202的第二端可以与终端设备中的一个信号源电连接。如此，终端设备中的信号源的电流可以通过馈电部传输到馈电臂上，然后通过馈电臂耦合到目标辐射体和第二金属凹槽，即可以使得目标辐射体和第二金属凹槽产生感应电流，从而可以使得目标辐射体和第二金属凹槽产生电磁波，如此，本公开实施例提供的天线单元可以将终端设备中的5G毫米波信号辐射出去。
本公开实施例中，由于终端设备可以通过馈电部将信号传输到馈电臂上，且馈电臂可以通过馈电部将信号传输到终端设备中，因此，可以通过将馈电部设置在第一金属凹槽底部，并贯穿第一金属凹槽底部，使得馈电部的一端与终端设备中的信号源电连接，馈电部的另一端与馈电臂电连接。
可选的，本公开实施例中，第一种可能的实现方式中，如图3所示，上述M个馈电臂中的每个馈电臂203可以包括两个部件，分别为第一部件203a和第二部件203b。其中，第一部件203a可以与馈电部202连接，第二部件203b可以与第一部件203a连接。
本公开实施例中，由于当馈电部向馈电臂传输毫米波信号时，毫米波信号的阻抗可能发生跳变，因此可以通过上述第一部件缓冲馈电部向馈电臂传输的毫米波信号，并在该第一部件缓冲毫米波信号后，再将缓冲后的毫米波信号传输给上述第二部件，如此可以防止馈电部向馈电臂传输的毫米波信号的阻抗发生跳变，从而可以确保本公开实施例提供的天线单元的工作性能。
可选的，本公开实施例中，第二种可能的实现方式中，上述M个馈电臂中的每个馈电臂可以为一个金属片。示例性的，该M个馈电臂中的每个馈电臂可以为一个铜片。
可选的，本公开实施例中，上述M个馈电臂的形状可以为矩形。
当然，实际实现时，上述M个馈电臂还可以包括其它任意可能的实现方式，具体可以根据实际使用需求确定，本公开实施例不作限定。
本公开实施例中，由于不同形状、材质和结构的馈电臂对天线单元的工作性能的影响可能不同，因此，可以根据实际使用需求选择合适的馈电臂，以使得天线单元工作在合适的频率范围内。
可选的，本公开实施例中，上述M个馈电臂可以为两个馈电臂，该两个馈电臂可以相对设置在上述目标金属凹槽内。
可选的，本公开实施例中，当上述目标金属凹槽包括第一金属凹槽和第二金属凹槽时，上述两个馈电臂可以相对设置在上述第一金属凹槽内。
示例性的，如图4所示，为本公开实施例提供的天线单元在Y轴反向(例如图3所示的坐标系)上的一种俯视图。由图4可见，第一绝缘体205设置在第一金属凹槽201a内，且第一绝缘体205承载有目标辐射体204，相对设置的馈电臂2030和馈电臂2031位于第 一绝缘体和第一金属凹槽201a之间。
需要说明的是，由于当俯视本公开实施例提供的天线单元时，第二金属凹槽和馈电臂均不可见，因此为了准确地示意各个部件之间的关系，上述图4中的馈电臂(包括馈电臂2030和馈电臂2031)和第二金属凹槽201b均是以虚线示意的。并且，由于图4为本公开实施例提供的天线单元在Y轴反向上的俯视图，因此图4示意的坐标系仅示意了X轴和Z轴。
另外，由于第一绝缘体设置在第一金属凹槽内，因此图4中的201a指示的是第一金属凹槽的开口边缘，以表示第一绝缘体205设置在第一金属凹槽201a的开口内。并且，由图4可见，馈电臂2030和馈电臂2031分布在第一金属凹槽201a的对角线L1上。
本公开实施例中，由于每个馈电部与一个馈电臂电连接，且上述两个馈电臂相对设置在目标金属凹槽内，因此，上述M个馈电部可以相对设置在目标金属凹槽底部。
可选的，本公开实施例中，与上述两个馈电臂电连接两个馈电部连接的信号源的幅值相等，相位相差180度。
需要说明的是，本公开实施例中，当上述两个馈电臂中的一个馈电臂处于工作状态时，另一个馈电臂也可以处于工作状态。
可选的，本公开实施例中，上述两个馈电臂的对称轴可以与目标辐射体的一条对角线平行。
当然，实际实现时，上述两个馈电臂还可以以其它分布方式分布在目标金属凹槽内。具体可以根据实际使用需求确定，本公开实施例不作限定。
可选的，本公开实施例中，上述M个馈电臂为四个馈电臂(即M＝4)，该四个馈电臂可以组成两个馈电臂组，每个馈电臂组分别可以包括两个馈电臂。
本公开实施例中，由于本公开实施例提供的天线单元包括两个馈电臂组，因此可以使得本公开实施例提供的天线单元满足MIMO技术的原理，从而可以提高天线单元的通信容量和通信速率。
本公开实施例中，如图5所示，一个馈电臂组可以包括馈电臂2032和馈电臂2033，另一个馈电臂组可以包括馈电臂2034和馈电臂2035。其中，馈电臂2032和馈电臂2033形成的馈电臂组可以为一个第一极化的馈电臂组；馈电臂2034和馈电臂2035形成的馈电臂组可以为一个第二极化的馈电臂组。
本公开实施例中，上述两个馈电臂组可以为两个不同极化的馈电臂组，即上述第一极化和第二极化可以为不同方向的极化。
需要说明的是，本公开实施例中，上述两个馈电臂组的极化形式可以为任意可能极化形式。具体可以根据实际使用需求确定，本公开实施例不作限定。
本公开实施例中，由于上述两个馈电臂组可以为两个不同极化的馈电臂组因此可以使得本公开实施例提供的天线单元可以形成一个双极化的天线单元，如此可以减小天线单元通信断线的概率，即可以提高天线单元的通信能力。
可选的，本公开实施例中，上述两个馈电臂组可以包括第一馈电臂组和第二馈电臂组，该第一馈电臂组中的馈电臂可以分布在目标金属凹槽的第一对角线上，该第二馈电臂组中的馈电臂分布在目标金属凹槽的第二对角线上。
可选的，本公开实施例中，上述第一对角线和上述第二对角线可以为目标金属凹槽的、 与目标金属凹槽开口所在表面平行的截面中的两条对角线。
可以理解，上述两个馈电臂组中的馈电臂可以位于同一平面上。
本公开实施例中，由于在上述M个馈电臂中的每个馈电臂均与辐射体(例如上述目标辐射体或目标金属凹槽)的距离均相等的情况下，可以便于控制该M个馈电臂与辐射体耦合的参数，例如耦合过程中产生的感应电流等，因此可以将上述两个馈电臂组均设置在同一平面上，从而可以便于控制本公开实施例提供的天线单元的工作状态。
可选的，本公开实施例中，上述第一对角线和第二对角线可以为目标金属凹槽中的两条正交的对角线。
可选的，本公开实施例中，当上述目标金属凹槽包括第一金属凹槽和第二金属凹槽时，上述第一馈电臂组中的馈电臂可以分布在第一金属凹槽的一条对角线上，上述第二馈电臂组中的馈电臂分布在第一金属凹槽的另一条对角线上。
示例性的，假设目标金属凹槽包括第一金属凹槽和第二金属凹槽，且第一金属凹槽的开口形状和第二金属凹槽的开口形状均为正方形，第一馈电臂组包括馈电臂2032和馈电臂2033，第二馈电臂组包括馈电臂2034和馈电臂2035，那么，如图5所示，馈电臂2032和馈电臂2033可以分布在第一金属凹槽201a的一条对角线L2上，馈电臂2034和馈电臂2035可以分布在第一金属凹槽201a的另一条对角线L3上。如此，第一馈电组包括的馈电臂与第二馈电臂组包括的馈电臂正交。
可选的，本公开实施例中，对于第一馈电臂组中的两个馈电臂，与这两个馈电臂电连接的两个馈电部连接的信号源(具体可以为5G毫米波信号源)的幅值可以相等，与这两个馈电臂电连接的两个馈电部连接的信号源的相位可以相差180度。
相应的，对于第二馈电臂中的两个馈电臂，与这两个馈电臂电连接的两个馈电部连接的信号源的幅值也可以相等，与这两个馈电臂电连接的两个馈电部连接的相位也可以相差180度。
本公开实施例中，当第一馈电臂组中的一个馈电臂处于工作状态时，第一馈电臂组中的另一个馈电臂也可以处于工作状态。相应的，当第二馈电臂组中的一个馈电臂处于工作状态时，第二馈电臂组中的另一个馈电臂也可以处于工作状态。即同一馈电臂组中的馈电臂是同时工作的。
可选的，本公开实施例中，第一馈电臂组中的馈电臂处于工作状态时，第二馈电臂组中的馈电臂可能处于工作状态，也可能不处于工作状态。具体可以根据实际使用需求确定，本公开实施例不作限定。
本公开实施例中，由于上述第一馈电臂组和上述第二馈电臂组正交分布，且与同一个馈电臂组中的两个馈电臂电连接两个馈电部连接的信号源的幅值相等，相位相差180度，因此可以提升第一馈电臂组和上述第二馈电臂组构成的天线路径之间的隔离度，从而可以提升天线单元性能。
可选的，本公开实施例中，上述第一绝缘体的形状可以与目标金属凹槽的开口形状相同，例如长方体或圆柱体等任意可能的形状。
需要说明的是，本公开实施例中，上述第一绝缘体的形状还可以为任意可以满足实际使用需求的形状。具体可以根据实际使用需求确定，本公开实施例不作限定。
可选的，本公开实施例中，上述第一绝缘体的材料可以为相对介电常数小于3的绝缘 材料。
可选的，本公开实施例中，上述第一绝缘体的材料可以塑胶或者泡沫等任意可能的材料。具体可以根据实际使用需求确定，本公开实施例不作限定。
示例性的，本公开实施例中，上述第一绝缘体的材料的相对介电常数可以为2.2的塑胶。
本公开实施例中，上述第一绝缘体不仅可以承载上述目标辐射体，还可以隔离目标辐射体和M个馈电臂，从而可以防止目标辐射体和M个馈电臂之间产生干扰。
需要说明的是，本公开实施例，在承载上述目标辐射体的前提下，第一绝缘体的材料的相对介电常数越小，该第一绝缘体对天线单元的辐射效果的影响越小。也就是说，上述第一绝缘体的材料的相对介电常数越小，第一绝缘体对天线单元的工作性能影响越小，天线单元的辐射效果越好。
可选的，本公开实施例中，上述目标辐射体可以为多边形辐射体。
可选的，本公开实施例中，上述目标辐射体可以为矩形辐射体、六边形辐射体或正方形辐射体等任意可能的多边形辐射体。具体可以根据实际使用需求确定，本公开实施例不作限定。
当然，实际实现时，上述目标辐射体的形状还可以为任意可能的形状，具体可以根据实际使用需求确定，本公开实施例不作限定。
可选的，本公开实施例中，如图4或图5所示，上述目标辐射体204的面积可以小于上述第二金属凹槽201b的开口面积。
本公开实施例中，由于上述目标辐射体与上述M个馈电臂耦合产生的电磁波的频率与目标辐射体的面积有关，具体的，目标辐射体的面积越小，目标辐射体与上述M个馈电臂耦合产生的电磁波的频率越高，因此将上述目标辐射体设置为多边形辐射体，可以使得目标辐射体与M个馈电臂耦合产生高频的电磁波，从而可以使得本公开实施例提供的天线单元工作在5G毫米波频段内。
可选的，本公开实施例中，目标辐射体的谐振频率可以为第一频率，目标金属凹槽的谐振频率可以为第二频率。
其中，上述第一频率可以大于上述第二频率。
本公开实施例中，由于不同辐射体的谐振频率不同，因此上述目标辐射体的谐振频率和目标金属凹槽的谐振频率可以为不同的频率，从而可以使得天线单元覆盖不同的频段。
示例性的，假设上述目标辐射体为正方形辐射体，如图6所示，为本公开实施例提供的天线单元工作时，天线单元的反射系数图。当回波损耗为-6dB(分贝)时，天线单元覆盖的频率范围可以为26.3GHz-43.1GHz，该频率范围可以包括多个毫米波频段(例如n257、n259、n261和n260等)；当回波损耗为-10dB时，天线单元覆盖的频率范围可以包括27.2GHz-29.7GHz和36.9GHz-41.7GHz，该两个频率范围包括多个主要的毫米波频段(例如n261和n260等)。如此，本公开实施例提供的天线单元可以覆盖大多数5G毫米波频段(例如n257、n259、n260、n261等主流的5G毫米波频段)，从而可以提高终端设备的天线性能。
需要说明的是，本公开实施例中，当一个天线单元的回波损耗小于-6dB时，该天线单元可以满足实际使用需求；当一个天线单元的回波损耗小于-10dB时，该天线单元的性能 更加优良。上述图6中的点a、点b、点c、点d、点e和点f用于标记回波损耗的数值，由图6可见，点a和点f标记的回波损耗的数值为-10，点b、点c、点d和点e标记的回波损耗的数值为-6。即本公开实施例提供的天线单元可以在满足实际使用需求的基础上，保证更加优良的性能。
可选的，本公开实施例中，上述目标辐射体可以与目标金属凹槽的开口所在表面齐平。
可选的，本公开实施例中，当上述目标金属凹槽包括第一金属凹槽和第二金属凹槽时，上述目标辐射体可以与第一金属凹槽的开口所在表面齐平。
示例性的，如图7所示，目标辐射体204与第一金属凹槽201a开口所在表面齐平。
需要说明的是，如图7所示，目标辐射体204承载在第一绝缘体205上；馈电部202设置在第一金属凹槽201a底部，且贯穿第一金属凹槽201a底部。
当然，实际实现时，上述目标辐射体还可以位于上述目标金属凹槽内的任意可能的位置，具体可以根据实际使用需求确定，本公开实施例不作限定。
本公开实施例中，由于目标辐射体所在的位置不同，天线单元的性能也可能不同，因此可以根据实际使用需求设置上述目标辐射体的位置，从而可以使得天线单元的设计更加灵活。
可选的，本公开实施例中，天线单元还可以包括设置在目标金属凹槽底部与上述第一绝缘体之间的第二绝缘体，上述M个馈电臂可以承载在该第二绝缘体上。
可选的，本公开实施例中，上述第二绝缘体的形状可以与目标金属凹槽的开口形状相同，例如长方体或圆柱体等任意可能的形状。
需要说明的是，本公开实施例中，上述第二绝缘体的形状可以为任意可以满足实际使用需求的形状，本公开实施例对此不作具体限定，具体可以根据实际使用需求确定。
可选的，本公开实施例中，上述第二绝缘体的材料可以为相对介电常数小于3的绝缘材料。
可选的，本公开实施例中，上述第二绝缘体的材料可以塑胶或者泡沫等任意可能的材料。具体可以根据实际使用需求确定，本公开实施例不作限定。
示例性的，本公开实施例中，上述第二绝缘体的材料的相对介电常数可以为2.5的塑胶。
需要说明的是，本公开实施例，在承载上述M个馈电臂的前提下，第二绝缘体的材料的相对介电常数越小，该第二绝缘体对天线单元的辐射效果的影响越小。也就是说，上述第二绝缘体的材料的相对介电常数越小，第二绝缘体对天线单元的工作性能影响越小，天线单元的辐射效果越好。
可选的，本公开实施例中，当目标金属凹槽包括第一金属凹槽和第二金属凹槽时，上述第二绝缘体可以设置在第一金属凹槽底部和上述第一绝缘体之间。
可选的，本公开实施例中，上述第二绝缘体的材料可以与上述第一绝缘体的材料相同。
本公开实施例中，当上述第二绝缘体的材料与上述第一绝缘体的材料相同，第二绝缘体可以看作第一绝缘体的一部分。如此，上述M个馈电臂也可以承载在第一绝缘体上。
示例性的，如图7所示，M个馈电部203承载在第一绝缘体205上。
本公开实施例中，上述第二绝缘体不仅可以承载上述M个馈电臂，还可以隔离该M个馈电臂和目标金属凹槽，从而可以方式该M个馈电臂与目标金属凹槽之间产生干扰。
可选的，本公开实施例中，如图7所示，第一金属凹槽201a底部还可以设置有贯穿第一金属凹槽201a底部的M个通孔207，上述M个馈电部中的每个馈电部202可以分别设置在一个通孔207中。
可选的，本公开实施例中，上述M个通孔可以为直径相同的通孔。
可选的，本公开实施例中，上述M个通孔可以分布在第一金属凹槽的对角线上。具体的分布方式可以根据上述M个馈电部在第一金属凹槽中分布的位置确定，本公开实施例不作限定。
本公开实施例中，通过在上述第一金属凹槽底部设置贯穿上述第一金属凹槽底部的通孔，并将上述M个馈电部设置在这些通孔中的方式，可以使得M个馈电部设置在第一金属凹槽的底部、且贯穿第一金属凹槽底部，如此可以简化馈电部贯穿第一金属凹槽的工艺。
可选的，本公开实施例中，上述每个通孔内可以设置有第三绝缘体，该第三绝缘体可以围绕上述馈电部设置。
本公开实施例中，上述第三绝缘体围绕上述馈电部设置，可以使得馈电部固定在通孔中。
示例性的，如图7所示，第一金属凹槽201a底部设置有通孔207，每个通孔207中设置有第三绝缘体208，馈电部202可以穿过通孔207中设置的第三绝缘体208，与馈电臂203电连接。
需要说明的是，图7中与馈电部202的一端连接的信号源30可以为终端设备中的毫米波信号源。
本公开实施例中，上述第三绝缘体的材料可以为相对介电常数比较小的绝缘材料。
示例性的，上述第三绝缘体的材料可以为泡沫材料或者塑胶材料等任意可能的材料。
可选的，本公开实施例中，上述第三绝缘体可以与上述第一绝缘体的材料为同一种绝缘材料，也可以为不同的绝缘材料。具体可以根据实际使用需求确定，本公开实施例不作限定。
本公开实施例中，一方面，由于通孔的直径可能大于馈电部的直径，因此当馈电部设置在通孔中时，该馈电部可能无法固定在该通孔中，因此通过在通孔中设置上述第三绝缘体，且该第三绝缘体围绕馈电部设置的方式，可以使得馈电部固定在通孔中。另一方面，由于第一金属凹槽和馈电部均为金属材质，在天线单元工作的过程中，两者之间可能会产生干扰，因此可以通过在通孔中增加上述第三绝缘体的方式隔离馈电部与第一金属凹槽，使得馈电部与第一金属凹槽绝缘，从而可以使得终端设备的天线性能更加稳定。
需要说明的是，本公开实施例中，上述各个附图所示的天线单元均是以结合本公开实施例中的一个附图为例示例性的说明的。具体实现时，上述各个附图所示的天线单元还可以结合上述实施例中示意的其它可以结合的任意附图实现，此处不再赘述。

本公开实施例中，可以通过在终端设备的壳体中设置上述至少一个第一凹槽，并将本公开实施例提供的天线单元设置在该第一凹槽内，实现在终端设备中集成至少一个本公开实施例提供的天线单元。
可选的，本公开实施例中，上述第一凹槽可以设置在终端设备的壳体的边框中。
本公开实施例中，如图8所示，终端设备4可以包括壳体40。壳体40可以包括第一金属边框41，与第一金属边框41连接的第二金属边框42，与第二金属边框42连接的第三金属边框43，与第三金属边框43和第一金属边框41均连接的第四金属边框44。终端设备4还可以包括与第二金属边框42和第四金属边框44均连接的地板45，以及设置在第三金属边框43、部分第二金属边框42和部分第四金属边框4所围成的区域的第一天线46(具体的，这些金属边框也可以为第一天线中的一部分)。其中，第二金属边框42上设置有第一凹槽47。如此，本公开实施例提供的天线单元可以设置该第一凹槽内，从而可以使得终端设备中包括本公开实施例提供的天线单元形成的阵列天线模组，进而可以实现在终端设备中集成本公开实施例提供的天线单元的设计。
本公开实施例中，上述地板可以为终端设备中的PCB或金属中框，或者为终端设备的显示屏等任意可以作为虚拟地的部分。
需要说明的是，本公开实施例中，上述第一天线可以为终端设备的第二代移动通信系统(即2G系统)、第三代移动通信系统(即3G系统)，以及第四代移动通信系统(即4G系统)等系统的通信天线。上述集成在终端设备中的天线单元(凹槽结构和位于该凹槽结构内的目标绝缘层形成的天线单元)可以为终端设备的5G系统的天线。
可选的，本公开实施例中，上述第一金属边框、第二金属边框、第三金属边框和第四金属边框可以依次首尾连接形成封闭式边框；或者，上述第一金属边框、第二金属边框、第三金属边框和第四金属边框中的部分边框可以连接形成半封闭式边框；或者，上述第一金属边框、第二金属边框、第三金属边框和第四金属边框可以互不连接形成开放式边框。具体可以根据实际使用需求确定，本公开实施例不作限定。
需要说明的是，上述图8所示的壳体40包括的边框是以第一金属边框41、第二金属边框42、第三金属边框43和第四金属边框44依次首尾连接形成的封闭式边框为例进行示例性的说明的，其并不对本公开实施例造成任何限定。对于上述第一金属边框、第二金属边框、第三金属边框和第四金属边框之间以其它连接方式(部分边框连接或各个边框互不连接)形成的边框，其实现方式与本公开实施例提供的实现方式类似，为避免重复，此处不再赘述。
可选的，本公开实施例中，上述至少一个第一凹槽可以设置壳体的同一边框中，也可以设置在不同的边框中。具体可以根据实际使用需求确定，本公开实施例不作限定。
可选的，本公开实施例中，终端设备的壳体上可以设置有多个第一凹槽，从而可以在终端设备中设置多个本公开实施例提供的天线单元，从而可以使得终端设备中包括多个天线单元，以提升终端设备的天线性能。
本公开实施例中，当终端设备中设置有多个天线单元时，根据天线单元的结构，可以缩小相邻两个第一凹槽之间的距离，即缩小相邻两个天线单元间隔的距离，如此可以在终端设备包括较少数量的天线单元情况下，增大天线单元中的目标辐射体和目标金属凹槽产生的电磁波的波束的扫描角度，从而可以增大终端设备的毫米波天线通信的覆盖范围。
本公开实施例中，可以通过在终端设备的壳体上设置至少一个第一凹槽，并在每个第一凹槽中设置一个本公开实施例提供的天线单元，以使得终端设备中可以集成至少一个本公开实施例提供的天线单元，以提高终端设备的天线性能。
可选的，本公开实施例中，上述目标金属凹槽可以为终端设备的壳体的一部分。可以理解，该目标金属凹槽可以为终端设备的壳体上设置的凹槽。
其中，终端设备的壳体可以为蜂窝天线的辐射体或非蜂窝天线的辐射体。

可选的，本公开实施例中，上述目标金属凹槽可以设置在终端设备的壳体的金属边框上。
示例性的，如图9所示，本公开实施例提供的终端设备4的壳体40中可以设置有至少一个目标金属凹槽201，天线单元中的第一绝缘体、M个馈电臂、M个馈电部以及承载在第一绝缘体上的目标辐射体均可以设置在该目标金属凹槽内(实际中，图9示意的终端设备的角度，目标金属凹槽不可见)。
可选的，本公开实施例中，一个目标金属凹槽可以设置在壳体的第一金属边框、第二金属边框、第三金属边框或第四金属边框中。具体可以根据实际使用需求确定，本公开实施例不作限定。

本公开实施例中，终端设备的壳体也可以为终端设备中非毫米波天线的辐射体，如此可以大幅缩小终端设备中的天线所占用的空间。
需要说明的是，本公开实施例中，上述图9均是以上述目标金属凹槽201设置在壳体40的第一金属边框41上，且目标金属凹槽201的开口方向为如图9所示的坐标系的Y轴正向为例进行示例性说明的。
可以理解，本公开实施例中，如图9所示，当上述目标金属凹槽设置在壳体的第二金属边框中时，目标金属凹槽的开口方向可以X轴正向；当上述目标金属凹槽设置在壳体的第三金属边框上时，目标金属凹槽的开口方向可以为Y轴反向；当上述目标金属凹槽结构设置在壳体的第四金属边框上时，目标金属凹槽的开口方向可以为X轴反向。
可选的，本公开实施例中，终端设备的壳体中可以设置目标金属凹槽，并在每个目标金属凹槽内设置第一绝缘体等部件，以使得终端设备中可以集成多个本公开实施例提供的天线单元，如此这些天线单元可以形成天线阵列，从而可以提高终端设备的天线性能。
可选的，本公开实施例中，在终端设备中集成多个本公开实施例提供的天线单元的情况下，相邻两个天线单元之间间隔的距离(即相邻两个目标金属凹槽之间间隔的距离)可 以根据天线单元的隔离度和该多个天线单元形成的天线阵列的扫描角度确定。具体可以根据实际使用需求确定，本公开实施例不作限定。
可选的，本公开实施例中，终端设备的壳体中设置的目标金属凹槽的数量可以根据目标金属凹槽结构的尺寸和终端设备的壳体的尺寸确定。本公开实施例对此不作限定。
示例性的，如图10所示，为本公开实施例提供的壳体上设置的多个天线单元在Y轴正向(如图9所示的坐标系)上的仰视图。如图10所示，第三金属边框43上设置有本公开实施例提供的多个天线单元(每个天线单元由壳体上的目标金属凹槽和位于该目标金属凹槽内的第一绝缘体等部件形成)。其中，第一绝缘体205设置在目标金属凹槽(未在图10中示出)中，目标辐射体204承载在第一绝缘体205中。
需要说明的是，本公开实施例中，上述图10中仅是以第三金属边框上设置的4个天线单元为例进行示例性说明的，其并不对本公开实施例形成任何限定。可以理解，具体实现时，第三金属边框上设置的天线单元的数量可以根据实际使用需求确定，本公开实施例不做任何限定。
本公开实施例提供一种终端设备，该终端设备包括天线单元。该天线单元可以包括目标金属凹槽，设置在目标金属凹槽底部M个馈电部，设置在目标金属凹槽内的M个馈电臂和第一绝缘体，以及该第一绝缘体承载的目标辐射体；其中，该M个馈电部中的每个馈电部分别与一个馈电臂电连接，且M个馈电部与目标金属凹槽绝缘，该M个馈电臂位于目标金属凹槽底部和第一绝缘体之间，且该M个馈电臂沿目标金属凹槽的对角线方向分布，以及该M个馈电臂中的每个馈电臂均与目标辐射体和目标金属凹槽耦合，目标辐射体的谐振频率与目标金属凹槽的谐振频率不同，M为正整数。通过该方案，一方面，由于馈电臂与目标辐射体和目标金属凹槽均耦合，因此在馈电臂接收到交流信号的情况下，馈电臂上可以与目标辐射体和目标金属凹槽进行耦合，从而可以使得目标辐射体和目标金属凹槽产生感应的交流信号，进而可以使得馈电臂、目标辐射体和目标金属凹槽产生一定频率的电磁波；并且，由于目标辐射体和目标金属凹槽产生感应电流的位置不同(电流流过的路径不同)，因此馈电臂上的电流经由目标辐射体和目标金属凹槽产生的电磁波的频率也不同，如此可以使得天线单元覆盖不同的频段，即可以增加天线单元覆盖的频段。另一方面，由于M个馈电臂位于目标金属凹槽底部与第一绝缘体之间，且M个馈电臂沿目标金属凹槽的对角线方向分布，因此可以在满足天线单元的性能的前提下，可以适当缩小天线单元的体积，从而可以使得天线单元的结构更加紧凑。如此，由于可以增加天线单元覆盖的频段，并且可以提高天线单元结构的紧凑程度，因此可以提高天线单元的性能。
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。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如 ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本公开各个实施例所述的方法。
上面结合附图对本公开的实施例进行了描述，但是本公开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公开的启示下，在不脱离本公开宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本公开的保护之内。
