本公开实施例涉及通信技术领域，尤其涉及一种毫米波天线阵列及移动终端。The embodiments of the present disclosure relate to the field of communications technologies, and in particular, to a millimeter wave antenna array and a mobile terminal.
随着移动通信技术的发展，智能手机和平板电脑等移动终端成为了人们日常生活中不可或缺的工具。天线作为实现移动终端的信号收发的组件，从而满足人们对于移动终端的通信功能以及数据传输等功能的需求。且由于5G(第五代移动通信)的脚步日益接近，故5G相关的天线需求便日益旺盛与受到瞩目，其中，对终端天线设计最具挑战性与新颖性的便是毫米波的天线阵列设计。毫米波天线阵列的主要无线性能要求包含有较高的增益(以克服毫米波高频的路径损耗)与较广的空间覆盖(以减小无线通信的盲区)，而毫米波天线阵列的尺寸大小当然也是整体设计考量的参数之一。With the development of mobile communication technologies, mobile terminals such as smartphones and tablets have become indispensable tools in people's daily lives. The antenna serves as a component for realizing signal transmission and reception of the mobile terminal, thereby satisfying people's requirements for communication functions of the mobile terminal and functions such as data transmission. And because the pace of 5G (fifth generation mobile communication) is getting closer, the demand for 5G-related antennas is growing and attracting attention. Among them, the most challenging and novel design for terminal antennas is the millimeter-wave antenna array design. . The main wireless performance requirements of millimeter-wave antenna arrays include higher gain (to overcome the path loss of millimeter-wave high-frequency) and wider spatial coverage (to reduce the dead zone of wireless communication), while the size of the millimeter-wave antenna array Of course, it is also one of the parameters of the overall design considerations.
而5G毫米波天线阵列目前主流方案为透过***封装SiP(system in package)的方式，形成AiP(Antenna in Package)天线(可为多层版的堆叠结构)，即毫米波天线阵列与射频芯片封装成一模块。为了达到上述的无线性能目的，现今阵列中常用的天线单元往往包含了贴片天线(patch antenna)，而多个贴片天线间，为了减少相互的耦合(coupling)造成性能的劣化，一般贴片天线间的距离需间隔半个导波波长(half guided wavelength,即λ
g/2)或以上，如图1所示，其中四个灰块即为贴片天线。但这样的间距造成毫米波天线阵列的尺寸较大，对整合入移动终端设备，尤其是手机，往往会造成设备整体尺寸较大，或造成既有天线(如：LTE天线，GPS天线，或WiFi天线)有效辐射空间的减少，进而使得产品竞争力下降或既有天线性能下降，而使得用户无线体验的劣化。
The mainstream solution of the 5G millimeter wave antenna array is to form an AiP (Antenna in Package) antenna (which can be a multi-layer stack structure) by means of a system package (SiP), that is, a millimeter wave antenna array and a radio frequency chip. Packaged into a module. In order to achieve the above wireless performance, the antenna units commonly used in arrays today often include patch antennas, and between the plurality of patch antennas, in order to reduce the mutual coupling performance degradation, the general patch The distance between the antennas needs to be separated by a half guided wavelength (λ g /2) or more, as shown in FIG. 1 , where four gray blocks are patch antennas. However, such a spacing causes the size of the millimeter wave antenna array to be large, and integration into mobile terminal devices, especially mobile phones, often results in a large overall size of the device or an existing antenna (eg, LTE antenna, GPS antenna, or WiFi). The antenna) reduces the effective radiation space, which in turn leads to a decrease in product competitiveness or a decrease in the performance of the existing antenna, which degrades the user's wireless experience.

下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。The technical solutions in the embodiments of the present disclosure are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present disclosure.

本公开实施例中，上述第一隔离结构30可以增加第一贴片天线10和第二贴片天线20之间的隔离度，从而可以减少第一贴片天线10和第二贴片天线20之间的相互耦合，故可使第一贴片天线10和第二贴片天线20之间的间距减小，实现第一贴片天线10和第二贴片天线20之间的间距小于半个导波波长，以缩小毫米波天线阵列的尺寸，减小毫米波天线阵列在移动终端中占 据的内部空间。In the embodiment of the present disclosure, the first isolation structure 30 can increase the isolation between the first patch antenna 10 and the second patch antenna 20, so that the first patch antenna 10 and the second patch antenna 20 can be reduced. The mutual coupling between the first patch antenna 10 and the second patch antenna 20 is reduced, and the spacing between the first patch antenna 10 and the second patch antenna 20 is less than half a guide. The wave wavelength reduces the size of the millimeter wave antenna array and reduces the internal space occupied by the millimeter wave antenna array in the mobile terminal.
应当说明的是，上述毫米波天线阵列包括至少两个贴片天线，且上述第一贴片天线10和第二贴片天线20为上述至少两个贴片天线中任意相邻的两个贴片天线，且上述毫米波天线阵列中，存在至少一组相邻的两个贴片天线中可以设置有上述第一隔离结构30，例如：上述毫米波天线阵列中，任意相邻的两个贴片天线之间的间隙内均可以设置有上述第一隔离结构30，从而缩小毫米波天线阵列的尺寸。It should be noted that the millimeter wave antenna array includes at least two patch antennas, and the first patch antenna 10 and the second patch antenna 20 are any two adjacent patches of the at least two patch antennas. In the above-mentioned millimeter wave antenna array, at least one set of two adjacent patch antennas may be disposed with the first isolation structure 30, for example, any two adjacent patches in the millimeter wave antenna array. The first isolation structure 30 described above may be disposed in the gap between the antennas, thereby reducing the size of the millimeter wave antenna array.
本公开实例中，上述第一隔离结构30可以是任何用于增加第一贴片天线10和第二贴片天线20之间的隔离度的结构，且该第一隔离结构30部分或者全部设置于第一贴片天线10和第二贴片天线20之间，以实现减小第一贴片天线10和第二贴片天线20之间的相互耦合。In the example of the present disclosure, the first isolation structure 30 may be any structure for increasing the isolation between the first patch antenna 10 and the second patch antenna 20, and the first isolation structure 30 is partially or completely disposed on Between the first patch antenna 10 and the second patch antenna 20, the mutual coupling between the first patch antenna 10 and the second patch antenna 20 is reduced.
其中，上述第一隔离结构30可以是仅设置有一个接地点的接地结构；或者，也可以是仅设置有一个馈电点的天线，如单极天线或者“T”形天线；或者，还可以是设置有一个接地点以及一个馈电点的天线，如偶极天线、倒“F”(Inverted-F)天线或者环形(Loop)天线等，由于上述接地结构以及各天线的结构为本领域技术人员所熟知，在此并不进行赘述。The first isolation structure 30 may be a ground structure provided only with one grounding point; or, may be an antenna provided only with one feeding point, such as a monopole antenna or a “T” antenna; or, An antenna provided with a grounding point and a feeding point, such as a dipole antenna, an inverted "F" (Inverted-F) antenna, or a loop antenna, etc., because the above-mentioned grounding structure and the structure of each antenna are technical in the art. It is well known to the person and will not be described here.
上述第一隔离结构30可以是部分设置于一相邻的两个贴片天线之间的间隙内，可选的，如图3和图4所示，上述毫米波天线阵列还可以包括第三贴片天线40和第四贴片天线50，所述第一贴片天线10、所述第二贴片天线20、所述第三贴片天线40以及所述第四贴片天线50之间两两相邻且间隔设置；所述第一隔离结构30为包括第一天线臂31和第二天线臂32的偶极天线，所述第一天线臂31与所述第二天线臂32位于同一直线上且间隔设置，所述第一天线臂31上设置有馈电点(以黑色实心点表示)，且所述第一天线臂31位于所述第一间隙内；所述第二天线臂32上设置有接地点(以空心圆点表示)，且所述第二天线臂32位于所述第三贴片天线40与所述第四贴片天线50之间的第二间隙内。The first isolation structure 30 may be partially disposed in a gap between two adjacent patch antennas. Optionally, as shown in FIG. 3 and FIG. 4, the millimeter wave antenna array may further include a third sticker. a patch antenna 40 and a fourth patch antenna 50, and between the first patch antenna 10, the second patch antenna 20, the third patch antenna 40, and the fourth patch antenna 50 Adjacent and spaced apart; the first isolation structure 30 is a dipole antenna including a first antenna arm 31 and a second antenna arm 32, and the first antenna arm 31 and the second antenna arm 32 are in the same line And spaced apart, the first antenna arm 31 is provided with a feeding point (indicated by a black solid point), and the first antenna arm 31 is located in the first gap; the second antenna arm 32 is disposed There is a grounding point (indicated by a hollow dot), and the second antenna arm 32 is located in a second gap between the third patch antenna 40 and the fourth patch antenna 50.
本实施方式中，一偶极天线的两个天线臂可以分别设置于一相邻的两个贴片天线之间的间隙内，即第一天线臂31设置于第一间隙内，且第二天线臂32设置于第二间隙内，从而可以同时缩小第一贴片天线10和第二贴片天线 20的间距以及第三贴片天线40和第四贴片天线50之间的间距，使毫米波天线阵列的尺寸缩小，且结构简单，同时因加入偶极子天线(作为隔离结构)，故可助增强毫米波天线阵列宽边(broadside)(即朝向+z方向)辐射的增益与垂直及水平双极化(dual-polarization)性能。In this embodiment, the two antenna arms of a dipole antenna can be respectively disposed in a gap between two adjacent patch antennas, that is, the first antenna arm 31 is disposed in the first gap, and the second antenna is disposed. The arm 32 is disposed in the second gap so that the pitch of the first patch antenna 10 and the second patch antenna 20 and the spacing between the third patch antenna 40 and the fourth patch antenna 50 can be simultaneously reduced, so that the millimeter wave The size of the antenna array is reduced and the structure is simple, and the addition of a dipole antenna (as an isolation structure) can enhance the gain and vertical and horizontal radiation of the broadside (ie, toward the +z direction) of the millimeter wave antenna array. Dual-polarization performance.
另外，上述第一贴片天线10与第三贴片天线40之间的间隙，以及第二贴片天线20和第四贴片天线50之间的间隙内也可以设置一偶极天线，该偶极天线的一个天线臂设置于第一贴片天线10与第三贴片天线40之间的间隙，另一个天线臂设置于第二贴片天线20和第四贴片天线50之间的间隙内，且该偶极天线的两条天线臂所在的直线，与上述位于第一间隙和第二间隙内的偶极天线的两条天线臂所在的直线垂直，从而可助增强毫米波天线阵列宽边(即朝向+z方向)辐射的增益与垂直及水平双极化性能。In addition, a gap between the first patch antenna 10 and the third patch antenna 40, and a gap between the second patch antenna 20 and the fourth patch antenna 50 may also be provided with a dipole antenna. One antenna arm of the pole antenna is disposed in a gap between the first patch antenna 10 and the third patch antenna 40, and the other antenna arm is disposed in a gap between the second patch antenna 20 and the fourth patch antenna 50. And the straight line of the two antenna arms of the dipole antenna is perpendicular to the line of the two antenna arms of the dipole antenna located in the first gap and the second gap, thereby helping to enhance the wide side of the millimeter wave antenna array (ie towards the +z direction) the gain of the radiation and the vertical and horizontal dual polarization performance.
上述第一隔离结构30也可以是全部设置于一相邻的两个贴片天线之间的间隙内，如图5所示，上述所述第一隔离结构30可以为包括第三天线臂33和第四天线臂34的偶极天线，所述第三天线臂33和所述第四天线臂34位于同一直线上且间隔设置，所述第三天线臂33上设置有馈电点，以及所述第四天线臂34上设置有接地点；所述第三天线臂33和所述第四天线臂34位于所述第一间隙内，从而可以进一步增强第一贴片天线10和第二贴片天线20之间的隔离度，使第一贴片天线10和第二贴片天线20之间的间距更小，以缩小毫米波天线阵列的尺寸，同时因加入偶极子天线(作为隔离结构)，故可助增强毫米波天线阵列宽边(即朝向+z方向)辐射的增益与垂直及水平双极化性能。The first isolation structure 30 may also be disposed in a gap between two adjacent patch antennas. As shown in FIG. 5, the first isolation structure 30 may include a third antenna arm 33 and a dipole antenna of the fourth antenna arm 34, the third antenna arm 33 and the fourth antenna arm 34 are located on the same line and spaced apart, the third antenna arm 33 is provided with a feeding point, and the The fourth antenna arm 34 is provided with a grounding point; the third antenna arm 33 and the fourth antenna arm 34 are located in the first gap, so that the first patch antenna 10 and the second patch antenna can be further enhanced The isolation between 20 causes the spacing between the first patch antenna 10 and the second patch antenna 20 to be smaller to reduce the size of the millimeter wave antenna array, and at the same time, by adding a dipole antenna (as an isolation structure), Therefore, it can enhance the gain and vertical and horizontal dual polarization performance of the wide side of the millimeter wave antenna array (ie, toward the +z direction).
或者，以上述第一隔离结构30为单极天线为例，如图6所示，上述第一隔离结构30也可以为包括第五天线臂35的单极天线，所述第五天线臂35位于所述第一间隙内，且所述第五天线臂35上设置有馈电点，通过在第一间隙内设置单极天线，从而可以减小第一贴片天线10和第二贴片天线20之间的相互耦合，使第一贴片天线10与第二贴片天线20之间的间距缩小，同时因加入单极子天线(作为隔离结构)，故可助增强毫米波天线阵列宽边(即朝向+z方向)辐射的增益与垂直及水平双极化性能。Alternatively, the first isolation structure 30 is a monopole antenna. As shown in FIG. 6, the first isolation structure 30 may also be a monopole antenna including a fifth antenna arm 35, and the fifth antenna arm 35 is located. In the first gap, and the fifth antenna arm 35 is provided with a feeding point, by providing a monopole antenna in the first gap, the first patch antenna 10 and the second patch antenna 20 can be reduced. The mutual coupling between the first patch antenna 10 and the second patch antenna 20 is reduced, and the wide side of the millimeter wave antenna array can be enhanced by adding a monopole antenna (as an isolation structure) ( That is, toward the +z direction, the gain of the radiation and the vertical and horizontal dual polarization performance.
当然，为了可助毫米波天线阵列达到垂直与水平的双极化的性能，毫米 波天线阵列中两两相邻的四个贴片天线，每相邻的两个贴片天线之间的间隙内均可以设置一个单极天线或者偶极天线，即如图5和图6所示的第一贴片天线10、第二贴片天线20、第三贴片天线40和第四贴片天线50中，任意两相邻的贴片天线之间的间隙内可以设置一个单极天线或者偶极天线。Of course, in order to help the millimeter wave antenna array achieve the vertical and horizontal dual polarization performance, two adjacent two patch antennas in the millimeter wave antenna array are in the gap between each adjacent two patch antennas. A monopole antenna or a dipole antenna may be provided, that is, in the first patch antenna 10, the second patch antenna 20, the third patch antenna 40, and the fourth patch antenna 50 as shown in FIGS. 5 and 6. A monopole antenna or a dipole antenna may be disposed in the gap between any two adjacent patch antennas.
应当说明的是，当上述第一隔离结构30为天线(如单极天线或者偶极天线等)时，第一隔离结构30的天线臂的形状以及尺寸等不同，第一贴片天线10和第二贴片天线20之间增加的隔离度不同，故设置第一隔离结构的天线臂的形状以及尺寸合适，可以进一步增加第一贴片天线10和第二贴片天线20之间的隔离度，从而进一步缩小毫米波天线阵列的尺寸。It should be noted that when the first isolation structure 30 is an antenna (such as a monopole antenna or a dipole antenna, etc.), the shape and size of the antenna arm of the first isolation structure 30 are different, and the first patch antenna 10 and the first The increased isolation between the two patch antennas 20 is different, so that the shape and size of the antenna arm of the first isolation structure are appropriate, and the isolation between the first patch antenna 10 and the second patch antenna 20 can be further increased. Thereby the size of the millimeter wave antenna array is further reduced.
另外，上述第一隔离结构30可以为包括设置有馈电点以及接地点的天线(如偶极天线、倒“F”天线或者环形天线)，且各天线中馈电点和接地点的设置位置固定，例如：如图3所示，第一隔离结构30为偶极天线，偶极天线中的馈电点和接地点，分别位于偶极天线中两个天线臂相对设置的臂端等。由于各天线中馈电点和接地点的设置位置为本领域技术人员熟知，在此并不进行赘述。In addition, the first isolation structure 30 may be an antenna including a feeding point and a grounding point (such as a dipole antenna, an inverted "F" antenna or a loop antenna), and a feeding position of the feeding point and the grounding point in each antenna.
