液晶天线阵列包括控制线和多个阵列排布的液晶天线单元,液晶天线单元包括液晶层和位于液晶层两侧的电极,控制线用于向液晶层两侧的施加电压,并改变加载至液晶层的电场,以此改变液晶层的介电常数,进而改变电磁波的传输相位,再通过一定的算法对不同液晶天线单元上加载不同的电场,达到波束控制的目的。
相关技术中,每个液晶天线单元均需进行独立控制,因此,需在每个液晶天线单元上均连接控制线。为避免控制线对微波信号传输造成影响,控制线通常需尽可能地远离液晶天线单元。但随着液晶天线阵列规模的扩大,控制线不可避免地会靠近液晶天线单元,同时由于液晶天线单元间距有限(一般为半波长,也可为0.3~0.9倍波长的任意值),有限的间距也限制了控制线的数量,进而限制了液晶天线阵列的规模。

液晶天线单元A包括微波信号收发单元30和连接于微波信号收发单元30的至少一条信号传输线10。信号传输线10的数量可以为一条、两条或三条等,如图1、图2、图6和图7所示,液晶天线单元A包含一条信号传输线10,如图3、图4、图8和图9所示,液晶天线单元A包含两条信号传输线10,如差分线,具体本公开不做限定。信号传输线10包括移相区01。控制线L用于一一对应地向移相区01提供电压信号。
微波信号收发单元30用于接收或发射微波信号。如图5所示,液晶天线阵列还包括液晶层50和位于液晶层50两侧的两个基板40,两个基板40和液晶层50对盒形成液晶盒。信号传输线10和控制线L设于基板40靠近液晶层50的一侧,移相区01在基板40上的正投影和液晶层50在基板40上的正投影至少部分重叠;移相区01可位于信号传输线10的任意区域,可以是部分区域也可以是全部区域,具体可不做限定。微波信号收发单元30设于基板40远离液晶层50的一侧。微波信号收发单元30可以是收发一体单元,如反射式液晶天线单元,也可以包括独立的微波信号接收单元和微波信号发射单元,如透射式液晶天线单元,具体本公开不做限定。当微波信号收发单元30包括微波信号接收单元和微波信号发射单元时,两者可分别位于两个基板40远离液晶层50的一侧。
在本公开一些实施例中,控制线L靠近基板40的一侧与基板40之间的距离为第一距离,信号传输线10靠近基板40的一侧与基板40之间的距离为第二距离,第一距离和第二距离相等,第一距离和第二距离可以等于或大于0。在该实施例中,第一距离和第二距离相等即意味着控制线L靠近基板40的一侧和信号传输线10靠近基板40的一侧大致在同一水平面上,也即说明两者之间未设有其他膜层。该种结构设置工艺简单,有助于节约生产。举例而言,在实际生产过程中,可在基板40的某一区域形成信号传输线10,在基板40的另一区域形成控制线L,在形成控制线L时,只要控制线L与对应的信号传输线10具有移相区01的部分解除,即可完成控制线L与移相区01的连接,无需再额外通过其他导电层或设置通孔等方式进行转接,工艺过程简单,操作方便。当然,本公开中控制线L靠近基板40的一侧和信号传输线10靠近基板40的一侧也可不在同一水平面上,其中信号传输线10位于控制线L远离基板的一侧,具体本公开可不做限定。
本公开液晶阵列天线的工作原理简述如下:微波信号收发单元30接收微波信号,并通过信号传输线10进行传输,在传输过程中通过控制线L施加不同电压信号至信号传输线10,改变液晶层50的介电常数,等效于改变了信号传输线10的电长度,不同电压信号下液晶天线单元A对应不同相位延迟,通过控制相位延迟参数,使得电磁波在外空间相互耦合,在 目标方向形成主波束,通过微波信号收发单元30完成微波信号的发射。
如图1至图4所示,多个液晶天线单元A中至少有部分液晶天线单元A的信号传输线10包括间隔分布的一条第一子线11和至少一条第二子线12,第一子线11包括移相区01。即多个液晶天线单元A中至少有部分液晶天线单元A的信号传输线10被分割为一条第一子线11和至少一条第二子线12。举例而言,液晶天线阵列包括16个液晶天线单元A,其中有12个液晶天线单元A的信号传输线10被分割为一条第一子线11和至少一条第二子线12。在该内容中,被分割的液晶天线单元A的数量仅是举例说明,对本公开不构成限定。具体地,被分割的液晶天线单元A的数量可根据实际的液晶天线阵列的结构进行设定。此外,液晶天线单元A中信号传输线10被分割成的第二子线12的数量也可根据液晶天线阵列的结构进行设定。
控制线L用于一一对应地向移相区01提供电压信号,当液晶天线单元A的信号传输线10包括第一子线11和第二子线12时,该液晶天线单元A的移相区01对应的控制线L与第一子线11连接,以为第一子线11提供电压信号,进而为第一子线11上的移相区01提供电压信号。在此需说明的是,液晶天线阵列中控制线L的数量和移相区01的数量相等。举例而言,如图3和图4所示,液晶天线阵列包括16个液晶天线单元A,每一个液晶天线单元A具有两条信号传输线10,两条信号传输线10均具有移相区01,则液晶天线阵列中控制线L的数量为16×2=32条。且连接于每个液晶天线单元A并为该液晶天线单元A提供控制信号的控制线L为两条,且两条控制线L分别与两条信号传输线10的移相区01连接,以为对应的移相区01提供电压信号。在本公开一些实施例中,当液晶天线单元A包括至少两条信号传输线10,信号传输线10的移相区01至少部分重叠,具体地两者在基板40上的正投影至少部分重叠。

位于相邻两个控制子段20之间的液晶天线单元A的信号传输线10包括第一子线11和第二子线12,该液晶天线单元A两侧的控制子段20和该液晶天线单元A的同一条第二子线12连接,连接于相邻两个控制子段20之间的第二子线12复用为控制线L。举例而言,控制线L包括两段控制子段20,控制子段20和液晶天线单元A交替排列,即两个控制子段20之间具有一个液晶天线单元A,且该液晶天线单元A的信号传输线10被分割为一条第一子线11和至少一条第二子线12,则两个控制子段20与其中的第二子线12连接,且该第二子线12复用为控制线L,即两个控制子段20以及中间连接的第二子线12三者组合形成完整的控制线L。

控制线L沿第一方向X延伸,多条控制线L沿第二方向Y排列形成控制线组2,控制线组2内控制线L的数量与天线单元组1内移相区01的数量相等。如,当天线单元组1包含m个液晶天线单元A,每个液晶天线单元A包含x条信号传输线10,信号传输线10具有移相区01,则控制线组2内控制线L的数量为m×x条,m,x选自大于等于1的任意整数。同样,液晶天线阵列也可以包含多个控制线组2,多个控制线组2沿第二方向Y排列。
控制线L具有第一端和第二端,控制线L的第一端用于连接电压信号 端In,多条控制线L的第一端位于天线单元组1在第一方向X上的同一侧,控制线L的第二端用于连接对应的移相区01。控制线L第一端可连接至驱动芯片,驱动芯片向液晶天线单元A提供驱动信号。在该实施例中,控制线L的第一端可以为该控制线L的电压信号输入端,第二端可以为该控制线L的电压信号输出端。

在本公开一些实施例中,天线单元组1包含m个液晶天线单元A,每个液晶天线单元A包含x条信号传输线10,控制线组2内控制线L的数量为m×x条,m,x选自大于等于1的任意整数。
天线单元组1中液晶天线单元A的编号为Ai,i选自1,2,3,4......m-1,m;控制线组2中的用于向液晶天线单元Ai的移相区01提供电压信号的控制线L的编号为Lj,j=i。在此需说明的是,如图3和图4所示,当液晶天线单元Ai具有两条信号传输线10,即具有两个移相区01时,对应的控制线LLj的数量可以为两条。

多条控制线L沿第二方向Y排列形成控制线组2,控制线组2内控制线L的数量与天线单元组1内移相区01的数量相等。如,当天线单元组1包含m个液晶天线单元A,每个液晶天线单元A包含x条信号传输线10,信号传输线10具有移相区01,则控制线组2内控制线L的数量为m×x条,m,x选自大于等于1的任意整数。同样,液晶天线阵列也可以包含多个控制线组2,多个控制线组2沿第二方向Y排列。
控制线L具有第一端和第二端,控制线L的第一端用于连接电压信号端In,多条控制线L的第一端位于天线单元组1在第一方向X上的同一侧,控制线L的第二端沿第一方向X延伸至对应的移相区01并与该移相区01连接。控制线L第一端可连接至驱动芯片,驱动芯片向液晶天线单 元A提供驱动信号。在该实施例中,控制线L的第一端可以为该控制线L的电压信号输入端,第二端可以为该控制线L的电压信号输出端。
位于控制线L第一端和第二端之间液晶移相单元A的信号传输线10包括第一子线11和第二子线12,且第二子线12与部分控制线L的至少部分区域重叠且接触连接。
具体地,在图6至图9中,天线单元组1中液晶天线单元A的编号为Ai,i选自1,2,3,4......m-1,m;控制线组2中的用于向液晶天线单元Ai的移相区01提供电压信号的控制线L的编号为Lj,j=i,在此需说明的是,如图8和图9所示,当液晶天线单元Ai具有两条信号传输线10,即具有两个移相区01时,对应的控制线LLj的数量可以为两条。控制线L的第一端位于液晶天线单元A1远离液晶天线单元Am的一侧。控制线Lj的第二端沿第一方向X延伸至对应的液晶天线单元Ai的移相区01。位于控制线Lj第一端和第二端之间的液晶天线单元Ai-1、Ai-2、Ai-3......,A2、A1的信号传输线10的第二子线12与控制线Lj部分区域重叠且接触连接,该液晶天线单元Ai-1、Ai-2、Ai-3......,A2、A1的第二子线12复用为控制线Lj。

在此需说明的是,图6至图9的实施例对应图1至图4的实施例,区 别在于图1至图4的实施例中,部分控制线L做了分段分割,而图6至图9的实施例中控制线L未做分割,其他内容大致相同,可互作参考。
本公开中,控制线L在对液晶天线单元A进行控制时,控制信号一般为直流电或低频交流电,同时考虑工艺精度,至少需要在每两条控制线L之间存在几微米的间距,如相邻控制线L之间的间距大于等于5μm。在信号传输线10上,由于信号频率较高,波长较小,第一子线11、第二子线12之间数微米的间距对高频信号传输几乎无影响,依然可以保证信号传输线10的传输效果。而当控制线L与被分割后的信号传输线10连接时,由于信号传输线10的材料的电导率远高于控制线L的材料的电导率,如,信号传输线10的材料包括金属材料,控制线L的材料包括透明导电材料如氧化铟锡等,当然也可以包括金属材料,电压信号仍可沿信号传输线10传播。当控制线L传输直流或低频交流控制信号时,电压信号通过分割成较细的第一子线11或第一子线11进行传输,互不影响。在此需说明的是,控制线L的线宽和信号传输线10中分割成的第一子线11和第二子线12的线宽本公开不做限定,只要能满足对应的连接关系即可。
本公开还提供一种电子装置,包括上述任一实施例中的液晶天线阵列,该电子装置可以是显示装置可以是手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪、电子手表、智能手环等任何需要收发电磁波信号的产品或部件。
