天线阵列 技术领域
本发明涉及通信领域，尤其涉及天线阵列。
背景技术
随着新兴应用的发展，对无线接入网络的容量需求呈井喷式增长，传统低频无线通信频段(<6G)频谱资源已经耗竭，无法满足未来对无线接入大容量、高速需求，因此通信频率正在向更高频段方向发展。高频(>10G)通信特别是高频毫米波(>25G)段通信具有更宽的可用带宽，如典型区域的V波段具有57G～66G共9G的可用通信带宽，E波段这有71～76G/81～86G共10G的可用通信带宽，这是传统低频无法比拟的，更大的可用带宽意味着更大的通信容量和更高信号传输速率。毫米波频段通信的特性使得其成为未来无线接入通信领域的发展方向，其能够很好的满足高容量、高速率、多样化接入等需求。
同时，由于毫米波频段频率高，其空间传输的路径损耗较大，伴随频率的升高其路径损耗总体上呈上升趋势，为了实现同样的通信距离相比低频段通信其需求更高的天线增益。在当前的技术背景下，对于工作于E波段的系统，为了满足100米的通信距离至少需求30dBi的天线增益，此时对于典型的平板天线，波束宽度大约不到5°。同时为了满足多用户的接入需求，对于基站天线而言需要具备多波束特性以满足多用户同时接入需求，同时也需要多波束以实现具有一定角度宽度的扇区覆盖。
现有技术使用的传统的矩形栅格布阵的毫米波天线为单波束，覆盖范围有限，而在实现毫米波多波束天线方面存在成本高、实现难度大、增益不高、波束控制不灵活及系统复杂度高等缺点。

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的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创 造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
在本发明实施例中，下文中的所有方向图均为各向同性点源构成的阵列因子波束图，实际工作的阵列波束图为阵列因子波束图与单元天线辐射波束图的乘积。实际中阵列天线的波束图及性能包括增益及旁瓣主要由阵列自身排布方式决定，因此讨论阵列因子波束图即可很好的代表最终阵列天线的波束图及性能。
图1示出了传统的矩形栅格布阵的天线阵列，该传统天线阵列对应一个馈电口，以8*8维阵列为例，单元间距为0.8λ(0.8个波长)，其形成的三维波束图见图2，对应的二位波束图见图3，对应的一个切面的二维波束图见图4。从图2、3和4可见该天线阵列可以产生一个波瓣，即图中的峰值部分，该波瓣即为主瓣。从图4可知，一般以波瓣的峰值处向下3dB来确定该波瓣的波束宽度，即图4中A、B两点之间的距离，由图4可知该主瓣的波束宽度约为9°，主瓣所在的方向对应为系统的信号覆盖区域。也就是说，该传统的天线阵列为单波束，该单波束即主瓣产生的波束，对应波束宽度为9°。
在本发明实施例中，构建了一种新型的天线阵列，该天线阵列可以为毫米波天线阵列，该天线阵列可以产生多波束。具体地，该天线阵列可以是N*M维阵列，也就是该天线阵列包括N*M个天线单元，每个天线单元可以对应一个毫米波天线，M和N为大于1的整数，该天线阵列中的N*M个天线单元形成至少两个子阵列，也就是该天线阵列可以分为多个子阵列，即该天线阵列包括至少两个子阵列，且该天线阵列中的天线单元通过至少两个馈电口进行馈电，该天线阵列包括的同一子阵列中的天线单元与至少两个馈电口中的同一个馈电口相连接进行馈电。该天线阵列中一个天线单元只能通过该至少两个馈电口中的一个馈电口进行馈电，也就是该天线阵列中的一个天线单元只能属于一个子阵列，通过一个馈电口进行馈电。该天线阵列中每行相邻两个天线单元不共用一个馈电口进行馈电，也就是相邻的两个天线单元分别通过该至少两个馈电口中的不同的两个馈电口进行馈电，或者该天线阵列中每列相邻两个天线单元不共用一个馈电口进行馈电，又或者是每行与每列的相邻两个天线单元都满足不共用一个馈电口进行馈电。对于该天线阵列中的任意一个子阵列第一子阵列来说，该第一子阵列中每行相邻两个天线单元之间的距离大于或等于预设阈值和\或每列相邻两个天线单元之间的距离 大于或等于该预设阈值。
在本发明实施例中，根据阵列天线理论，当天线阵列中相邻的两个天线单元的间距大于1个工作波长时，必定会出现波瓣；当扫描阵列中相邻的两个天线单元间距大于0.5个工作波长时，扫描角度大于一定角度时，也会出现波瓣。
在本发明实施例中，由于新构建的天线阵列包括至少两个子阵列，且每个子阵列中相邻两个天线单元的距离大于或等于预设阈值，将该预设阈值设置为大于或等于1个工作波长时，根据上述天线理论，每个子阵列均可以产生多个波瓣，其中一个设置为主瓣，其余为副瓣，则新天线阵列可以产生多波束，扩大了覆盖范围。
在本发明实施例中，以图5为例进行说明，图5所示为本发明实施例的天线阵列示意图，该天线阵列为8*8维阵列，该阵列每个位置对应一个天线单元，即该阵列包括8*8＝64个天线单元。可选地，本发明的该天线阵列也可以不是方阵，可以为N*M维阵列，N和M可以相等或不相等，本发明并不限于此。图5中，该天线阵列中每行以及每列中相邻两个天线单元之间的间距为0.8λ，可选地，每行中相邻两个天线单元之间的间距可以相等，也可以不相等，同样地，每列中相邻两个天线单元之间的间距可以相等，也可以不相等，并且每行中相邻两个天线单元之间的距离与每列中相邻两个天线单元之间的距离可以相等，也可以不相等，本发明并不限于此。但考虑到该天线阵列的口径，口径相同的情况下，将该天线阵列设置为相邻天线单元之间的距离相等，可以提高利用效率，也可以简化设计，降低实现难度。并且为了进一步提高该天线阵列的效率，可以将每行相邻两个天线单元之间的间距设置为小于预设阈值，该预设阈值可以为小于1个工作波长的任意长度，例如0.7λ，同样地，每列相邻两个天线单元之间的间距设置也可以为小于预设阈值，本发明并不限于此。另外，考虑到天线之间的电磁互耦的作用，该天线阵列中相邻两个天线单元之间的间距一般要设置为大于或等于门限值，根据经验值，该门限值一般可以取0.5个工作波长，即天线阵列中相邻天线单元之间的间距设置不小于0.5个工作波长，但本发明并不限于此。
在本发明实施例中，图5中的天线阵列包括了四个子阵列，每个子阵列采用了不同的图形进行标识，每个子阵列均为4*4维阵列。可选地，天线阵列可以包括至少两个子阵列，即可以包括2个、3个或更多的子阵列；每个 子阵列可以为n*m维阵列，n和m可以相等也可以不相等，本发明并不限于此。
在本发明实施例中，将图5中的四个子阵列分别拆开，可以形成图6(a)至(d)的四个子阵列，以该天线阵列中包括的多个子阵列中任意一个子帧阵列为例，例如以图(a)为例，该子阵列中每行相邻的两个天线单元之间的距离为1.6λ，可选地，每行中相邻的两个天线单元之间的距离设置为大于或等于预设阈值的，根据天线阵列理论，该预设阈值可以设为大于1λ的任意数值，例如图(a)中的1.6λ，本发明并不限于此。同样地，每列之间的间距也可以设置为大于或等于预设阈值。可选地，每行的天线单元之间距离大于或等于预设阈值时，每列的天线单元之间的距离可以也大于或等于预设阈值，也可以小于预设阈值，同样地，将每列的天线单元之间的距离设置为大于或等于预设阈值时，每行的天线单元之间的距离可以也大于或等于预设阈值，也可以小于预设阈值。
在本发明实施例中，以图6(a)为例的子阵列，由于由图5可知，天线阵列中每行中天线单元之间的间距设置为相等，因此按照一定规律得到的图6(a)的子阵列中每行的天线单元之间的间距也相等。可选地，在设置子阵列时，可以设置为间距不相等，同样地，每列包括的每个天线单元之间的距离也可以设置为不相等，本发明并不限于此。例如，对于子阵列的每行来说，在设置为间距不相等时，对于该子阵列中每行包括的多个天线单元中，当存在两个相邻的天线单元之间的距离大于或等于预设阈值时，该天线阵列即可出现多波束。同样地，每列包括的天线单元可以进行相同的设置，并且当每行中已经存在两个相邻的天线单元之间的距离大于或等于预设阈值时，每列可以设置，也可以不设置两个相邻的天线单元之间的距离大于或等于预设阈值，本发明并不限于此。
在本发明实施例中，该天线阵列包括至少一个子阵列，对应的每个子阵列需要一个馈电口进行馈电，即该天线阵列对应至少两个馈电口。具体地，例如图5所示，天线阵列包括四个子阵列，则对应的包括四个馈电口，每个子阵列用一个馈电口，对于图6中任意一个子阵列来说，例如图6(a)的第一子阵列来说，该子阵列对应一个馈电口。可选地，对应一个馈电口的该子阵列中每个天线单元之间可以串馈，也可以并馈。例如图7所示，图中“Y”图形表示一个天线单元，该图中的多个天线单元构成一个子阵列，该子阵列 中包括的天线单元通过并馈连接到同一个馈电口，该子阵列通过该馈电口进行馈电。
在本发明实施例中，一个天线阵列包括至少两个子阵列，一个天线阵列对应了至少两个馈电口，一个子阵列用一个馈电口，可选地，可以对至少两个子阵列中至少一个进行馈电。具体地，为了获得更多的波束，可以通过调节每个子阵列的馈电相位，改变波束的指向，即可以获得更多波束，以图5为例，当该天线阵列包括四个子阵列时，该天线阵列也对应了四个馈电口，每个子阵列对应一个馈电口，可以分别通过四个馈电口给四个子阵列馈电，也可以只通过其中一个馈电口给对应的其中一个子阵列进行馈电。即可以对图6(a)中子阵列通过馈电口进行馈电，而其它三个子阵列(b)至(d)不馈电，同样地，也可以只对图6中任意两个子阵列进行馈电，也可以对四个阵列同时都馈电，本发明并不限于此。当对该天线阵列中的多个子阵列进行馈电时，每个子阵列的馈电相位差可以不同，不同的相位进行馈电，可以调节每个子阵列的波束的指向，尽量使得每个子阵列产生多个波束，并且使每个波束的指向不重合，以便于获得更多得波束。
具体地，在本发明实施例中，在对天线阵列包括的至少两个子阵列中的子阵列进行馈电时，针对每个子阵列中统一子阵列的天线单元可以采用等幅同相位馈电，可以采用等幅不同相位进行供电，每个子阵列之间相比，也可以采用不同相位进行馈电，以便于产生更多的波瓣。可选地，每个子阵列中同一个子阵列也可以采用不等幅进行馈电，每个子阵列之间也可以采用不等幅进行馈电，本发明并不限于此。
具体地，以图6(a)进行说明，若对于该子阵列通过馈电口进行馈电，首先，可以采用等幅同相位馈电。如图8所示，该子阵列出现了9个峰值接近的波瓣，其中可以选择8个为副瓣，1个为主瓣。如图9所示为二维方向图，其为图8中沿π＝0方向的切面，因此有3个波瓣。即采用如图6(a)的子阵列既可以产生多个波瓣，则对应的会出现多个波束。
在本发明实施例中，仍然以图6(a)进行说明，若对于该子阵列通过馈电口进行馈电，采用等幅不同相位馈电，例如在θ方向采用等幅60°相位差进行馈电。如图10所示，出现了8个波瓣，其中可以选择7个为副瓣，1个为主瓣。如图11所示为二维方向图，其为图10中沿π＝0方向的切面，因此有4个波瓣。即采用如图6(a)的子阵列进行等幅不同相位进行馈电，可 以产生多个波瓣，则对应的会出现多个波束。并且可以通过调节相位差，使得子阵列的波瓣产生的位置发生变化，即可以调节该子阵列的波束的指向。当多个子阵列进行馈电时，每个子阵列采用不同的相位进行馈电，就可以产生更多的波瓣，即调节相位进行馈电让每个子阵列的波束在空间中互不交叠，每个波束的指向不同，也就是产生了更多的波束，这样可以进一步扩大空间覆盖范围。例如，对两个子阵列进行馈电，每个子阵列调节相位馈电都可以产生8个波瓣，再通过调节相位，使得每个子阵列的每个波瓣都不重合，则两个子阵列即可以产生16个波瓣，则该天线阵列包括16个波束，进一步扩大了覆盖面积。
在本发明实施例中，仍然以图6(a)进行说明，若对于该子阵列通过馈电口进行馈电，采用等幅不同相位馈电，并且是在两个方向上的不同相位差进行馈电，例如在θ方向采用等幅50°相位差进行馈电，同时在π方向采用45°相位差进行馈电。如图12所示，出现了9个波瓣，其中可以选择8个为副瓣，1个为主瓣。即采用如图6(a)的子阵列进行等幅不同相位进行馈电，可以产生多个波瓣，则对应的会出现多个波束。同样地，可以通过调节每个方向的相位差，使得波瓣产生的位置发生变化，即可以调节该子阵列的波束的指向。当多个子阵列进行馈电时，每个子阵列采用不同的相位差进行馈电，就可以产生更多的波瓣，即调节相位进行馈电让每个子阵列的波束在空间中互不交叠，每个波束的指向不同，也就是产生了更多的波束，这样可以进一步扩大空间覆盖范围。
因此，本发明实施例的天线阵列，当每个子阵列通过不同的相位差进行馈电时，可以通过调节相位差，使得每个子阵列都产生多个位置不同的波瓣，即该天线阵列可以产生多波束，并且通过相位差调节波束的位置和个数，扩大覆盖面积。
应理解，本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
在本发明实施例中，由于每个子阵列的口径与天线阵列的口径相比几乎一致，基于天线基本理论，口径与波束宽度的关系，子阵列的波束宽度将与天线阵列的波束宽度保持一致。由于子阵列会出现多个波瓣，对多个子阵列 进行馈电时，通过调节馈电的相位，改变每个馈电的子阵列产生的波束的指向，即可获得具有多个波束的天线阵列，因此本发明实施例的天线阵列可以显著扩大通信范围，提升系统覆盖角度区域，对于高频毫米波窄波束场景具有重要意义。
在本发明实施例中，天线阵列可以拆分为多个子阵列，由于每个子阵列中的相邻天线单元间距较大，因此每个子阵均会形成多个波瓣，同时各个子阵列的波束宽度将与天线阵列的波束保持大致一致，均为窄波束，单个主瓣或副瓣能够直接通信的角度范围并未扩大。对于有遮挡的场景，受到主瓣或副瓣照射的物体可以构成一个散射体，散射体将会在散射体周围特定区域形成较强的散射信号，对应的区域称为散射可通信区域，此时系统将充分运用遮挡体散射作用构成的散射波束扩大角度覆盖范围从而扩大通信范围，此时的可通信区域为主瓣或副瓣直接照射区域与散射可通信区域共同构成。实际通信场景多为人口众多的城市区域，具有充分的散射场景，因此，在子阵列形成的主瓣以外，多个副瓣也同样可提供多个可通信散射区域，因此扩大了系统的可通信区域，如图13所示。而对应传统阵列架构的天线阵列则只有一个主瓣，可提供一个可通信散射区域，无法有副瓣提供可通信散射区域，因此本发明实施例可以进一步扩大系统的覆盖范围。
在本发明实施例中，天线阵列可以拆分为多个子阵列，每个子阵列均能够生成多个波瓣波束，从而扩大通信范围。同时为了从距离方向上扩大通信范围，可以在不同子阵列之间形成的波束上采用MIMO技术，基于MIMO技术在相同的接收信噪比和通信距离条件下可以获得更低的接收信号误码率改善通信质量，在相同接收信噪比和误码率条件下则可以成倍扩大系统的通信距离，在相同的接收信噪比、误码率及通信距离条件下则可获得更大的系统容量。
在本发明实施例中，对于接入点稀少的传播场景，如农村、郊外等场景，希望获得更远的通信距离并减少系统的部署数量；对于接入点密集的传播场景，如市区场景，希望获得更宽的角度覆盖范围。为了获得特定场景下的最优天线配置，可以通过切换馈电网络来实现主阵与拆分子阵列的切换，如图14所示，可以采用开关等器件实现馈电口之间的切换，从而实现各种应用场景的灵活配置，降低了复杂度和系统成本。
因此，本发明实施例的天线阵列，通过将天线阵列拆分为多个子阵列， 并通过不同的馈电口进行馈电，从而产生多个波束，显著扩大毫米波窄波束场景下的通信覆盖范围，避免传统毫米波多波束高增益天线角度覆盖能力不足的缺点，同时由多个大单元间距的子阵列相互交叠实现阵列口径高效利用并提升天线覆盖范围，在扩大波束的空间覆盖范围的同时满足多用户的通信需求，系统波束控制简单，结构简单且实现容易，相对于传统方案可以实现低复杂度，低成本化。
