随着通信技术的发展,5G电调天线的应用也呼之欲出,5G大规模电调天线阵对移相器的要求也是越来越高,诸如要求多通道移相器共同使用,所以要求移相器的尺寸小、厚度薄、重量轻,并且尽量简化馈电线路等。

为了使本发明的目的、技术方案及优点更加清楚明白,下面通过具体实施方式结合附图对本发明实施例作进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
实施例一:
为了避免侧滑式介质板的移相器存在的厚度大,强度低,可调节范围小的问题,本实施例提出了一种移相器,可参见图2和图3,图2为本发明实施例提供的一种移相器的结构图;图3为本发明实施例提供的一种移相器的***图。该移相器包括了屏蔽件(第一层和第五层),以及设置于屏蔽件所形成的屏蔽空间内的可调介质层;可调介质层包括线路层(第二层、第三层和第四层)和介质件61、62,线路层包括馈电电路301以及与馈电电路对应设置的用于形成空气带线的空槽211、411,介质件***相应的空槽内,并通过控制其***空槽内的深度(例如,沿空槽纵向的***长度)改变馈电电路的介电常数。本实施例提供的移相器的屏蔽件是一层覆盖在 移相器外层上的金属壳,通过该层金属壳将移相器内部的馈电电路与外部隔离开,避免产生干扰。在屏蔽件的中间或内部设有移相器的可调介质层,可调介质层可以通过改变介质件的***深度来调整介电常数,达到改变信号相位的目的。可调介质层中包括了线路层和介质件,线路层又由馈电电路和空槽组成,在空槽和屏蔽件之间会形成一层空气带线,其中介质件就插在该空槽内,当介质件***空槽内时,空槽内的介质由空气变为介质件材料,随着介质的改变,馈电电路的介电常数也就发生了改变。
在本实施例中,线路层可包括线路承载板,线路承载板包括至少一个线路设置面,馈电电路形成于线路设置面上;线路层还包括设置在线路承载板两个设置面的第一支撑板和第二支撑板,第一支撑板和/或第二支撑板上形成有与其对应的线路设置面上所形成的馈电电路形状相匹配的通槽,以在承载板与第一支撑板和/或第二支撑板贴合时供馈电电路嵌入通槽内。承载板上有两个设置面,每一个设置面均可以用于贴敷线路层,因此线路层设置在承载板的一个设专面或者两个设置面上。在承载板两个设置面上号设置有两块支撑板,分别是第一支撑板和第二支撑板,当承载的设置面上设置有馈电电路时,需要在设置有馈电电路对应设置面的支撑板上挖出一个与馈电电路相同形状的通槽以容纳馈电电路。
在本实施例中,第一支撑板上设置有用于形成第一空气带线的第一空槽,第二支撑板上设置有用于形成第二空气带线的第二空槽。在本实施例中,第一支撑板和/或第二支撑板上不但设置有与馈电电路相同形状的通槽外,还包括了用于形成空气带线的空槽,第一支撑板对应的是第一空槽,第二支撑板上对应的是第二空槽,第一空槽和第二空槽所形成的空气带线完全相同,第一空槽可以是完全贯通第一支撑板的条形槽,也可以是一边开孔,另外一边封闭的凹槽;第二空槽可以是完全贯通第二支撑板的条形槽,也可以是一边开孔,另外一边封闭的凹槽。
在本实施例中,介质件包括用于***第一空槽的第一介质拉杆,以及用于***第二空槽的第二介质拉杆;第一介质拉杆与第二介质拉杆形状相同,且形状与输出信号相位变化的差分比值相关。第一介质拉杆位于第一空槽外的第一操作端和第二介质拉杆位于第二空槽外的第二操作端位于同一端,且在***和取出时同步运动。在本实施例中,介质件为介质拉杆,由于同时存在第一空槽和第二空槽,因此介质拉杆也同时存在第一介质拉杆和第二介质拉杆,由于第一介质拉杆和第二介质拉杆***第一空槽和第二空槽内时,可以调整馈电电路的介电常数,因此,可以通过改变第一介质拉杆和第二介质拉杆的形状来实现不同的输出信号相位变化的差分比值。为了实现第一介质拉杆和第二介质拉杆更好的匹配关系,第一介质拉杆和第二介质拉杆可具有相同的形状。在本实施例中,第一介质拉杆和第二介质拉杆均包括前端的***段和后端的操作端,前端的***段***空槽内调整介电常数,后端的操作端从空槽内伸出。在需要调整介质拉杆的***深度时,可以通过操作端进行调整,例如可以通过电机实现电动调节,还可以通过手工进行调节等。同样为了实现第一介质拉杆和第二介质拉杆更好的匹配关系,第一介质拉杆和第二介质拉杆在***和取出的过程中可保持同步运动,在本实施例中可以将第一介质拉杆和第二介质拉杆的操作端固定在一起实现同步运动,在另外一些实例中还可以在第一介质拉杆和第二介质拉杆的操作端上设置第一开孔和第二开孔,在使用时通过螺栓将第一开孔和第二开孔固定在一起进行同步运动。
目前的移相器中,由于介质板设置在移相器的侧面,因此移相器的信号输入线和信号引出线均是在移相器的侧面引出,这或导致移相器的厚度和重量的增加。在本实施例中,屏蔽件为内部形成有屏蔽空间的屏蔽壳,屏蔽壳上与馈电电路所在平面所平行的壳体面上设置有引线通孔,通过引线通孔与馈电电路的引脚连接。本实施例中,由于馈电电路被完全包裹在 屏蔽件内,因此,馈电线路的输入引线和输出引线均通过屏蔽件上的引线通孔引出。由于在屏蔽件和馈电电路之间还设置有一层支撑板,并且在支撑板上设置有与馈电电路相同的通槽,因此,在一些实施例中,可以将引线通孔的设置位置设置在与馈电电路的输入引脚和输出引脚对应的位置,以减少引线通孔与馈电电路的引脚连接的引线的长度。
在本实施例中,为了降低制作工艺的复杂度和制作难度,屏蔽件包括第一屏蔽板和第二屏蔽板,第一屏蔽板和第二屏蔽板覆盖在介质层的上方和下方,在第一屏蔽板和第二屏蔽板之间的空间可以形成屏蔽空间。由于屏蔽件的主要目的是屏蔽电磁干扰,因此第一屏蔽板和第二屏蔽板可以直接由金属板制成,还可以由PCB板制成,其中在PCB板的至少一面上覆盖有金属层。
在本实施例中,为了更进一步的压缩移相器的厚度和重量,将线路承载板、第一支撑板和第二支撑板均制成PCB板;当第一屏蔽板和第二屏蔽板为PCB板时,线路承载板、第一支撑板、第二支撑板、第一屏蔽板和第二屏蔽板互相压合,组成移相器。此外,当第一屏蔽板和第二屏蔽板为金属板时,线路承载板、第一支撑板和第二支撑板互相压合,再将第一屏蔽板和第二屏蔽板分别固定在第一支撑板和第二支撑板上,组成移相器。
本实施例提供了一种移相器,该移相器包括屏蔽件,以及设置于屏蔽件所形成的屏蔽空间内的可调介质层;可调介质层包括线路层和介质件,线路层包括馈电电路以及与馈电电路对应设置的用于形成空气带线的空槽,介质件***空槽内,并通过控制其***空槽内的深度改变馈电电路的介电常数。通过在介质层内的空槽中***介质件来实现馈电电路的介电常数的调整,减小了移相器的厚度和重量。
进一步地,本实施例的移相器中屏蔽件和可调介质层均采用PCB板或金属板制成,并且引线的引出方式是从屏蔽件的引线通孔中引出;采用PCB 板制制作,以及如此改变引线的引出位置可以进一步的缩小移相器的厚度和重量。
实施例二:
本实施例提供了一种电调天线,该电调天线包括了至少一个辐射单元和实施例一所提供的一种移相器;辐射单元通过移相器的引线孔与移相器内部的馈电电路连接;移相器通过控制介质件***空槽内的深度改变输出信号的相位,并通过辐射单元将改变相位后的输出信号发送出去。辐射单元固定在移相器的屏蔽件上。可以理解的是,在本实施例中,辐射单元的作用是将输出信号发送出去,因此辐射单元的个数可以根据实际情况进行设置。同时电调天线设置有实施例一所提供的一种移相器,其最外层的屏蔽件为金属,因此可以将辐射单元直接固定在移相器的屏蔽件上。在另外一些实施例中,将辐射单元分散的设置在其他位置,通过引线与移相器连接也可是可行的。
本实施例还提供了一种网络设备,参见图4所示。该网络设备包括处理器、通信总线以及上述的电调天线。电调天线用于改变输出信号的相位并将改变相位后的所述输出信号发送出去;通信总线用于实现处理器和电调天线之间的连接通信;处理器用于控制电调天线以改变输出信号的相位。
实施例三:
本实施例提供了一种移相器制作方法,参见图5所示,该移相器制作方法包括步骤S501至S504:
S501、在PCB基板板刻蚀出馈电电路凹槽和容纳介质件的空槽。

将介质件分别***到PCB基板两个设置面上分别刻蚀出的空槽内。
本实施例还提供了另外一种移相器制作方法,参见图6所示,本实施例中的移相器包括第一支撑PCB板、第二支撑PCB板和线路承载PCB板,以及第一屏蔽板和第二屏蔽板,所述第一屏蔽板和第二屏蔽板为金属板或PCB板。该移相器制作方法包括以下步骤S601至S605:

实施例四:
本实施例以PCB板制成的移相器为例,提供一种基于PCB形式实现的超薄介质移相器。参见图3,该移相器使用5层低成本PCB一体压合成型,或者3层PCB一体压合成型,在上下两边使用金属片或者双面金属PCB焊接成一体。所述第3层是PCB线路层,线路的上下两侧第2层和第4层是介质支撑层,线路区域的上下第2层和第4层掏空,形成空气带线,可减少线路损耗。介质片61、62在掏空区域移动,形成相位变化。第1层和第5层PCB(或金属片)为移相器的屏蔽层。
本移相器介质板在移相器腔体内滑动,使腔体内PCB电路在介质和空气之间变化,形成介质带状线和空气带状线转换,从而得到相位的线性变化。介质移相器由于不改变传输线路本身,具有设计容差敏感度小,损耗小,性能优良等特点。
本发明一种多路移相器由多层PCB一体压合成实现,线路区域为类空气带线,可实现低损耗;线路周围用金属过孔屏蔽,形成带状线或者类同轴结构,线路之间匹配可采用微四分之一波长阻抗或者渐变传输线阻抗匹配等形式。线路上下层端介质开槽,使介质滑杆可从槽内移动,形成空气带状线和介质带状线模式相换转换。介质拉杆采用两端局部开槽的方式完成匹配。线路层可集成馈电线路,末端出口可直连辐射体,整个移相器不用组装。重要的是降低了移相器的厚度和重量,重量不到之前移相器的1/3,厚度可以小于3mm。
实施例五:
本实施例以PCB板制成的移相器为例,提供了另外一种移相器。参见图7,该移相器由5层PCB压合而成,其中第三层PCB 30附着有馈电线路301,馈电线路301包括输入端口31和分路输出端口32、33、34、35;第二层支撑PCB 20和第四层支撑PCB 40压合在PCB 30的上下两侧,其中, 将馈电线路301在PCB 20和40上的区域空间挖空介质形成挖空区域(空槽)211和411,介质拉杆61,62可以在挖空区域211和411内同步滑动,介质拉杆在滑动过程中使得线路上下空间空气介质和拉杆介质之间转变,从而起到相位变化的效果,其中移相器的驻波特性可参见图10。第一层PCB 10和第五层PCB 50起屏蔽作用,在第一层PCB 10中设有移相器的输入端口11和分路输出端口12、13、14、15,输入端口11通过金属过孔和输入端口31导通,分路输出端口12、13、14、15通过金属过孔和分路输出端口32、33、34、35导通。信号从输入端口11输入,从分路输出端口12、13、14、15输出。当介质拉杆61、62同步移动时,分路输出端口12、13、14、15输出的信号相位镜像变化,差分比值为1:1:0:0或者0:0:-1:-1。图11到图14分别示出了相位的变化值。
图7中移相器也可由3层PCB压合而成,即由PCB 20,30,40压合而成;层10和50为屏蔽层,可由PCB或者金属片组成,后期经过表贴焊接等工艺形成移相器整体。
实施例六:
图8中显示的是一分三路移相器的本体的俯视图,叠层形式和实例一相同,图示没有显示上下屏蔽层。该移相器的本体包括介质支撑层b-10,一进三出的馈电线路b-12,介质拉杆b-11。其中,馈电线路b-12设有信号的输入端口b-121,以及信号的输出端口b-122、b-123、b-124,馈电线路b-12映射在介质支撑层b-10的介质板区域被掏空,介质拉杆b-11在滑动过程中改变各输出端口的相位。信号从输入端口b-121进入,从输出端口b-122、b-123、b-124输出。介质拉杆b-11左右平移,随着介质变化,各输出端口的相位的差分比值为0:1:0:-1。
实施例七:
图9中显示的是应用了本移相器的电调天线的俯视立体图,其中,移相器c-10和实例一相同。图中示出了信号输入端口c-20和介质拉杆c-30,并且还示出了辐射单元c-41、c-42、c-43、c-44。由于与相关技术的移相器相比,本实施例的移相器的出口位置在移相器的表面,所以可直接将辐射单元表贴焊接于移相器c-10的表面。由于本移相器的补偿线路都集成屏蔽在移相器内部,所以天线表面没有线路,天线表面没有表面波对天线波束的干扰,降低了天线的耦合效应;由于本移相器是多层PCB叠压成型,自身强度大,所以该天线不用金属底板作为支撑,进一步减轻了天线的重量。随之介质拉杆c-30在滑动过程中改变各辐射单元的输入相位,辐射单元c-41、c-42、c-43、c-44形成固定的相位差分变化,从而实现波束扫描。本实例只展示了双通道电调天线,在5G电调天线的应用上,可平面复制多通道天线网络,完全满足5G电调天线的应用。
本实施例的移相器为移相器创新应用PCB的这种叠层方式,在这种方式下,形成移相器的馈电线路布局于移相器PCB叠层内部,避免了天线表面波对天线波束的干扰,减小了天线的耦合,增加了天线的性能。另外,本发明移相器的输出端在移相器表面,利用移相器表面金属,可以直接链接天线阵子单元,减去了馈电线路的应用。本移相器可以复制集成多路移相网络,完全满足5G电调天线的应用。最后,由于本移相器是多层PCB叠压成型,所以本身强度大,可以取代了金属底板的作用,进一步降低了天线的重量。
