具体实施方式
为了方便理解本申请实施例提供的天线及通信系统，下面介绍一下其应用场景。图1示例性示出了本申请实施例适用的一种通信系统架构示意图，如图1所示，该通信系统可以为基站天馈系统。该应用场景可以包括基站和终端。基站和终端之间可以实现无线通信。该基站可以位于基站子系统(base station subsystem，BBS)、陆地无线接入网(UMTS terrestrial radio access network，UTRAN)或者演进的陆地无线接入网(evolved universal terrestrial radio access，E-UTRAN)中，用于进行无线信号的小区覆盖以实现终端设备与无线网络之间的通信。具体来说，基站可以是全球移动通信系统(global system for mobile communication，GSM)或(code division multiple access，CDMA)系统中的基地收发台(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的节点B(NodeB，NB)，还可以是长期演进(long term evolution，LTE)系统中的演进型节点B(evolutional NodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器。或者该基站也可以为中继站、接入点、车载设备、可穿戴设备以及新无线(new radio，NR)系统中的g节点(gNodeB或者gNB)或者未来演进的网络中的基站等，本申请实施例并不限定。
图2示出了基站的一种可能的结构示意图。基站通常可以包括天线1、安装架2、天线调整支架3等结构。天线1可通过天线调整支架3安装于安装架2，以便于天线1信号的接收或者发射。当然，图2所示的实施例仅仅作为一种可选的实现方式，具体实施时，本申请实施例中的天线及基站可能与图2所示的实施例不同，本申请不做限制。
另外，基站还可以包括射频处理单元4和基带处理单元5。例如，射频处理单元4可用于对天线1接收到的信号进行选频、放大以及下变频处理，并将其转换成中频信号或基带信号发送给基带处理单元5，或者射频处理单元4用于将基带处理单元5或中频信号经过上变频以及放大处理通过天线1转换成电磁波发送出去。基带处理单元5可通过射频处理单元4与天线1的馈电网络连接。在一些实施方式中，射频处理单元4又可称为射频拉远单元(remote radio unit，RRU)，或者，还可能是有源天线单元(Active Antenna Unit，AAU)中的射频模块，基带处理单元5又可称为基带单元(baseband unit，BBU)。
在一种可能的实施例中，如图2所示，射频处理单元4可与天线1一体设置，基带处理单元5位于天线1的远端。在另外一些实施例中，还可以使射频处理单元4和基带处理单元5同时位于天线1的远端。射频处理单元4与基带处理单元5可以通过电缆线6连接。
图3为本申请实施例中天线的一种可能的组成示意图，图4为本申请实施例中天线的一种侧向结构示意图。如图2、图3和图4所示，该天线1包括功分器11和辐射单元12。上述辐射单元12也可以称为天线振子、振子等，它能有效地发送或接收天线信号。在天线1中，不同辐射单元12的频率可以相同或者不同。上述功分器11包括腔体111和馈电网络112，上述馈电网络112上设置于腔体111内，从而腔体111可以保护馈电网络。辐射单元12与馈电网络112相连接，馈电网络112用于为辐射单元12馈电。具体的，上述馈电网络112通常由受控的阻抗传输线构成，馈电网络112可把信号按照一定的幅度、相位馈送到辐射单元12，或者将辐射单元12接收到的信号按照一定的幅度、相位发送到基站的基带处理单元。具体地，在一些实施方式中，馈电网络112可以用于实现不同辐射波束方向，或者与校准网络连接以获取系统所需的校准信号。在馈电网络112中还可能设置一些用于扩展性能的模块，例如合路器，可用于把不同频率的信号合成一路，通过辐射单元12发射；或者反向使用时，可以用于将辐射单元12接收到的信号，根据不同的频率分成多路传输到基带处理单元进行处理，又例如滤波器，用于滤除干扰信号。具体的实施例中，多个辐射单元12可以形成辐射单元阵列，以阵列的形式工作。
图5为本申请实施例中辐射单元的一种结构示意图，如图4和图5所示，本申请实施例中，天线1的辐射单元12包括辐射体121、馈电部件122和保护罩123。上述馈电部件122连接于馈电网络112与辐射体121之间，具体的，可以使上述馈电部件122的一端与馈电网络112连接，另一端与辐射体121连接。上述馈电部件122具体可以为导线的形式。上述辐射体121与保护罩123固定设置，形成一个整体，馈电部件122位于保护罩123内部。具体的，上述保护罩123与腔体111固定连接，使得辐射单元12固定于腔体111，且上述保护罩123与腔体111的表面形成容置腔，从而馈电部件122位于容置腔内。该实施例中，辐射单元12的馈电部件122直接与位于腔体111内的馈电网络112连接，因此，可以减少天线1中同轴线级联，有利于实现高效率辐射。进一步的，该天线1在同等覆盖信号强度的要求时需要的输入功率就减小，从而实现电能源的节省，进一步使得碳排放减少。
天线1中进行电连接的线路或者电路接口等对于防尘防水的需求较高，因此需要进行保护。该方案 中，每个辐射单元12的馈电部件122可以被容置腔保护，馈电网络112可以被腔体保护，则馈电部件122以及馈电网络112都可以得到独立的保护，从而，可以使得辐射单元12不包括天线罩。如此，该方案简化了天线1的结构，有利于减小天线1的风载，从而可以使得天线1不易受天面空间的限制。同等条件下，可以根据需求相对地增大天线1的尺寸，也即增加天线1的辐射单元12数量，从而增强天线1的性能收益。特别对于海域等空间较大且风力较大的区域，本申请的技术方案具有更加重要的意义。此外，本申请实施例的天线没有天线罩，还可以实现减重和降低成本的目的。
具体形成上述容置腔时，上述容置腔满足预设防护等级，使得容置腔能够进行一定程度的防尘和防水，则使得馈电部件122在上述容置腔内可以得到保护。
具体的实施例中，上述容置腔满足预设防护等级具体可以为IP(Ingress Protection)等级，IP等级是针对电气设备外壳对异物侵入的防护等级，来源是国际电工委员会的标准IEC 60529。在这个标准中，针对电气设备外壳对异物的防护，IP等级的格式为IPXX，其中XX为两个阿拉伯数字，第一标记数字表示接触保护和外来物保护等级。具体的，第一个标记数字为0表示“无防护，无特殊的防护”；第一个标记数字为1表示“防止大于50mm之物体侵入，防止人体因不慎碰到电气设备内部零件”；第一个标记数字为2表示“防止大于12mm之物体侵入，防止手指碰到电气设备内部零件”；第一个标记数字为3表示“防止大于2.5mm之物全侵入，防止直径大于2.5mm的工具，电线或物体侵入”；第一个标记数字为4表示“防止大于1.0mm之物体侵入，防止直径大于1.0mm的蚊蝇、昆虫或物体侵入”；第一个标记数字为5表示“防尘，无法完全防止灰尘侵入，但侵入灰尘量不会影响电气正常运作”；第一个标记数字为6表示“尘密，完全防止灰尘侵入”。第二标记数字表示防水保护等级，具体的，第二个标记数字为0表示“无防护，无特殊的防护”；第二个标记数字为1表示“防止滴水侵入，防止垂直滴下之水滴”；第二个标记数字为2表示“倾斜15度时仍防止滴水侵入，当电气设备倾斜15度时，仍可防止滴水”；第二个标记数字为3表示“防止喷射的水侵入，防止雨水、或垂直入夹角小于50度方向所喷射之水”；第二个标记数字为4表示“防止飞溅的水侵入，防止各方向飞溅而来的水侵入”；第二个标记数字为5表示“防止大浪的水侵入，防止大浪或喷水孔急速喷出的水侵入”；第二个标记数字为6表示“防止大浪的水侵入，电气设备浸入水中在一定时间或水压的条件下，仍可确保设备正常运作”；第二个标记数字为7表示“防止侵水的水侵入电气设备无期限的沉没水中在一定水压的条件下，仍可确保设备正常运作”；第二个标记数字为8表示“防止沉没的影响”。
可以使上述保护罩123与腔体111的表面形成的容置腔的防护等级高于或者等于IP24，从而向天线的馈电部件122提供较好的保护。以利于在没有天线罩的保护下，仍然可以较为有效的保护内部线路。具体的实施例中，上述容置腔的防护等级可以为IP34、IP44、IP45、IP46、IP55、IP56、IP57、IP64、IP66或者IP67等等。
在一些实施例中，如图4所示，上述天线1还包括巴伦124，该巴伦124连接于辐射体121与地之间，用于实现辐射体121的接地。具体的，该巴伦124可以一端与辐射体121连接，另一端与腔体111表面连接，也就是说，可以利用腔体111作为该天线的地，本申请不做具体限制。可选的，巴伦124也可以位于容置腔内，从而容置腔也可以保护巴伦124以及巴伦124与其它线路连接的接口。
在一些实施例中，上述功分器11还可以包括移相装置，该移相装置用来改变天线信号辐射的相位。移相装置具体设置于腔体111内，则腔体111可以保护移相装置。
具体实现上述辐射体121与保护罩123固定时，可以使上述辐射体121与保护罩123为一体成型结构。从而使得辐射体121与保护罩123之间的固定结构较为可靠，且密封性较好。具体的，上述辐射体121为金属材质，保护罩123为塑料等绝缘材质，则可以采用注塑成型的工艺制备形成上述辐射体121与保护罩123。当然，在其它实施例中还可以采用粘接、热熔连接或者可拆卸连接等工艺实现辐射体121与保护罩123的固定设置，本申请对此不做限制。
上述辐射体121至少部分结构位于保护罩123的外部，辐射体121位于保护罩123外部的区域的表面包裹有保护层，从而可以对辐射体121进行防腐蚀和防水等保护。具体的实施例中，上述保护层可以在辐射体121表面涂布形成，例如涂布聚酯漆等涂层。或者，其它实施例中，还可以在辐射体121的表面粘贴保护层或者套设保护层等，本申请对此不做限制。
本申请对上述辐射体121的具体结构不做限制。例如，辐射体121可以为贴片式辐射体，也可以为振子式辐射体，都可以采用本申请的技术方案。
在一些实现方式中，实现保护罩123与腔体111固定连接时，可以使保护罩123具有连接部1231， 该连接部1231与腔体111固定连接。该方案中，保护罩123具有连接部1231有利于简化保护罩123与腔体111的连接方式。此外，上述连接部1231与腔体111之间可以通过设置密封件，进一步提升保护罩123与腔体111表面形成的容置腔的密封等级。具体的，上述密封件可以为密封圈或者密封胶条等，本申请不做具体限制。
图6为本申请实施例中天线的一种爆炸结构示意图，请参考图4和图6，在一些实现方式中，上述连接部1231为保护罩123的第一凸沿，也就是说，保护罩123具有第一凸沿，该第一凸沿作为连接部1231，用于与腔体111固定连接。相应的，上述腔体111具有第二凸沿1111，上述第一凸沿和第二凸沿1111固定连接。该方案有利于简化保护罩123与腔体111之间的连接方式。例如，可以在第一凸沿制备通孔，在第二凸沿1111也制备通孔，利用螺栓穿过上述第一凸沿的通孔和第二凸沿1111的通孔以连接第一凸沿和第二凸沿1111。或者，还可以在上述第一凸沿制备通孔，而在第二凸沿1111制备螺纹孔，利用螺钉穿过上述第一凸沿的通孔并旋进螺纹孔，从而简化天线1的结构，减小天线1的体积。当然，还可以采用其它的连接方式实现保护罩123与腔体111的连接，例如卡接等，本申请对此不做限制。
请继续参考图4，在一些实现方式中，上述腔体111包括第一通孔1112和第二通孔1113，该第一通孔1112和第二通孔1113间隔预设距离，也就是说第一通孔1112和第二通孔1113不相连通。对于辐射单元12为双极化辐射单元的情况，上述馈电网络112可以包括第一馈电线和第二馈电线，辐射单元12的馈电部件122包括第一馈电部和第二馈电。上述第一馈电线与第一馈电部通过第一通孔1112连接，第二馈电线与第二馈电部通过第二通孔1113连接。具体的实施例中，上述第一馈电部和第二馈电部也可以为线状结构，上述第一馈电线与第一馈电部的连接点可以位于容置腔也可以位于腔体111，同样，第二馈电线与第二馈电部的连接点也可以位于容置腔或者位于腔体111，本申请对此不做限制。该方案中，第一通孔1112和第二通孔1113间隔预设距离，则可以认为上述第一通孔1112和第二通孔1113之间具有地层，使得辐射单元12在两个极化方向的信号的传输路径实现高隔离，减少相互串扰。
进一步的，图7为本申请实施例中天线的另一种侧向结构示意图，如图7所示，在一些实施例中，上述天线1还包括反射板13，该反射板13安装于腔体111与辐射单元12之间。反射板13也可以称为底板、天线面板或者反射面等，其可以是金属材质。天线1接收信号时，反射板13可以把天线信号反射到目标覆盖区域。天线1发射信号时，反射板13可以将射至反射板13的信号反射并发射出去。辐射单元12通常放置于反射板13一侧表面，这不但可以大大增强天线信号的接收或发射能力，还能够起到阻挡、屏蔽来自反射板13背面(本申请中反射板13的背面是指与反射板13用于设置辐射单元12相背的一侧)的其它电波对天线信号接收的干扰作用。
图8为本申请实施例中天线的一种俯向结构示意图，如图8所示，上述反射板13具体可以具有镂空结构131，从而减小反射板13产生的风载，减小整个天线1的风载，有利于增大天线1的尺寸，增多天线1的辐射单元12数量，以增强天线1的性能收益。
具体设置上述反射板时，可以利用绝缘连接件实现反射板13与腔体111的连接，从而减少对天线信号的干扰。具体的，上述绝缘连接件可以为柔性件，利用该柔性件将反射板13绑缚于腔体111上，以简化安装结构。且无需破坏腔体111本身的结构。变了便于实现上述柔性件的绑缚，可以在腔体111的外壁设置挂钩，使得柔性件挂于上述挂钩。
具体的实施例中，上述反射板还可以具有孔位，振子的巴伦124等结构可以穿过该孔位与功分器11连接。
以上实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在也包括例如“一个或多个”这种表达形式，除非其上下文中明确地有相反指示。
本申请中出现的“具体的”、“具体设置”和“具体设计”等涉及到“具体”字样的实施例，均指代可选的实施例，也就是说，该实施例是在本申请发明构思下一种可能的具体实施例，但是还包括其它可能的实施例。
在本申请中描述的参考“一个实施例”或“具体的实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
上述各个实施例可以为单独的实施例，也可以进行结合。例如将各个实施例中至少两个实施例中的技术特征结合形成新的实施例，本申请对此不做限制。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的保护范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
