Description

调节智能天线校准板的方法及装置 技术领域
本发明通常涉及移动通信领域，尤其涉及一种调节智能天线阵校准板的方法及装置。
背景技术
智能天线的概念是在20世纪80年代末针对移动通信技术的需要提出来的，可以提高移动通信系统的信道复用率、基站覆盖面积，并克服共信道、多径衰落等日益严重的干扰问题。
在使用智能天线时，必须具有对智能天线阵进行校准的技术。在TDD系统中使用智能天线时是根据电磁场理论中的互易原理，直接利用上行波束成型系数来进行下行波束成型。但对实际的无线基站，每一条通路的无线收发机不可能全部相同的，而且，其性能将随时间、工作电平和环境条件等因素变化。如果不进行校准，则下行波束成型将受到严重影响。不仅得不到智能天线的优势，还有可能导致完全不能通信。因此，智能天线阵的校准是智能天线中的一项核心技术。
波束赋形是一种基于天线阵列的信号处理技术，通过调整天线阵列中的每个阵元的加权系数产生具有指向性的波束，从而能够获得明显的阵列增益。但是这种技术对相位和幅度的误差非常敏感，因此，通常使用智能天线校准板来校准工作天线。所以，智能天线校准板的自身的误差必须控制在一定的范围以内。
根据传统的方法，功率幅度的调节可以通过在耦合器上加焊接或胶来实现。但是焊接对无源互调性能是有影响的，加胶则非常难以控制所加胶的量。相位的调节通常是通过切割和焊接印刷电路板微带线的尽头线来实现，同样，这种方法对于无源互调性能也会有影响。此外，调节多路径的天线和检查调节结果会花费相当的时间。尤其是在过度调节或需要反复多次调节的情况下，花费的时间更为可观。

具体实施方式
在以下优选的实施例的具体描述中，将参考构成本发明一部分的所附的附图。所附的附图通过示例的方式示出了能够实现本发明的特定的实施例。示例的实施例并不旨在穷尽根据本发明的所有实施例。需要说明的是，尽管附图中以特定顺序描述了本发明中有关方法的步骤，但是这并非要求或者暗示必须按照该特定顺序来执行这些操作，或是必须执行全部所示的操作才能实现期望的结果，相反，本文中所描述的步骤可以改变执行顺序。附加地或备选地，可以省略某些步骤，将多个步骤合并为一个步骤执行，和/或将一个步骤分解维多个步骤执行。
附图1示出了一个智能天线校准板的印刷电路的示意图。附图1包含了一个校准口和8个天线端口。其中，每一路的天线端口通过微带线耦接到相应的天线列，并在其通路中设有一个微带耦合器，所耦合的信号通过功分器合成至校准口。
附图2示出了量化调节智能天线校准板的配置装置200的示意图。如图2所示，网分仪210是用来测量智能天线校准板的天线端口的功率幅值和相位的。所述网分仪210设置有和所述智能天线校准板的天线端口耦接的输出端口和所述智能天线校准板校准口耦接的输入端口；所述网分仪210还设置有向量化调节判定器220输出信号的端口。
量化调节判定器220设置有接收来自于网分仪210的信号的输 入端口；还包括能显示所述智能天线校准板示意图以及覆盖在所述智能天线校准板上的所述塑料薄膜的位置和数量的可视化用户界面。
网分仪210输出测试信号到智能天线校准板的天线端口，所述测试信号通过智能天线校准板的耦合器耦合到智能天线校准板的校准口输出。智能天线校准板的输出信号作为网分仪210的输入信号。网分仪210将相应天线端口的功率幅度值和相位值发送给量化调节判定器220。
附图3示出了量化调节智能天线校准板的流程图。
在步骤S301中，量化调节判定器220根据接收到的来自于网分仪210的信号和智能天线校准板的产品标准(例如中国移动通信企业标准)来判定所述天线端口之间的功率幅度差值和相位差值。
在步骤S302中，量化调节判定器220根据步骤S301中判定的功率幅度差值及相位差值和智能天线校准板的产品标准来确定所需要调节的功率幅度差值和相位差值。
在步骤S303中，量化调节判定器220根据需要调节的功率幅度差值来确定覆盖在所述智能天线校准板上的塑料薄膜的位置和数量。
附图4示出了一个根据本发明实施例的智能天线校准板功率幅度调节的示意图。根据现有的例如中国移动通信企标规定，在天线端口之间的功率幅度差值应该小于0.7dB。根据经验，故障天线校准板的最大幅度差值大约是0.9dB。在不同的位置放置各种形状(例如方型、圆形、菱形、梯形等)的塑料薄膜，可以调节智能天线校准板的天线端口之间的功率幅度差值。所述塑料薄膜须具有稳定的介电常数。如附图4所示，作为一个实施例，当塑料薄膜的尺寸为8mm(长度)x3mmx(宽度)0.6mm(厚度)，将所述塑料薄膜放在如图4所示的例如位置A和位置B可以使得功率幅度值分别增加0.2dB和0.4dB。塑料薄膜的尺寸不仅限于上述实施例中的大小，其可以是任意符合智能天线校准板要求的尺寸。位置A和位置B通常是微带耦合器的位置，也可以是在所述智能天线校准板上的任何其他适合于调节功率幅度 的位置。因此根据需要将具有稳定介电常数的一块或多块塑料薄膜放在不同的位置可以实现量化地调节各天线端口之间的功率幅度值。具体地，表1给出了将塑料薄膜放置在如图4所示的位置A或位置B的功率幅度调节值，根据表1就可以以单块塑料薄膜的调节值0.2dB为步幅来量化地调节各天线端口的功率幅度。所述功率幅度步幅可以根据塑料薄膜的尺寸，厚度，介电常数或校准板的容差要求等来设置和确定。

表1不同位置的功率幅度调节值
在步骤S304中，量化调节判定器220根据需要调节的相位差值来确定覆盖在智能天线校准板上的塑料薄膜的位置和数量。
附图5示出了根据本发明的实施例的智能天线校准板相位调节的示意图。根据现有的例如中国移动通信企标规定，两个天线端口之间的相位差应该小于5°。根据经验，故障天线校准板的天线端口之间的最大差值大约是8°(电缆的相位容差为±2°，印刷电路板的相位容差为±2°)。在不同的位置放置各种形状(例如方型、圆形、菱形、梯形等)的塑料薄膜，可以调节天线端口之间的相位差值。所述塑料薄膜具有稳定的介电常数。如图5所示，作为一个实施例，当塑料薄膜的尺寸为8mm(长度)x3mmx(宽度)0.6mm(厚度)，将塑料薄膜放在图5的位置A可以调节左右两侧的天线端口的相位值。塑料薄膜的尺寸不仅限于上述实施例中的大小，其可以是任意符合智能天线校准板要求的尺寸。将塑料薄膜放在图5的位置B可以调节如图5所示的左侧的天线端口的相位值。因此根据需要将具有一定尺寸和稳定介电常数的一块或多块塑料薄膜放在不同的位置可以实现量化地 调节各天线端口之间的相位值。具体地，表2给出了将一块或多块塑料薄膜放置在如图5所示的例如位置A和位置B的相位调节值。图5所示的位置A，B通常分别是智能天线板上的微带支路，功分器支路的位置(例如功分器第二支路)，也可以是在所述智能天线校准板上的任何其他适合于调节相位的位置。例如，将两块塑料薄膜放在如图5所示的位置B的左侧，左侧的天线端口的相位值可以调节2°。将一块塑料薄膜放在如图5所示的位置A，可以将如图5中的左侧和右侧的天线端口的相位值各自调节1°。根据表2就可以以单块塑料薄膜的相位调节值1°为步幅来量化地调节各天线端口的相位值。所述相位步幅可以根据塑料薄膜的尺寸，厚度，介电常数或校准板的容差要求等来设置和确定。
左侧端口调节值 右侧端口调节值 数量 位置

0 2° 2 位置B(右)
0 3° 3 位置B(右)
1° 1° 1 位置A
表2不同位置和不同塑料薄膜数量的相位调节值
根据例如表1和表2所列的塑料薄膜的功率幅度和相位调节值以及现有的一些对智能天线校准板产品的规定，量化调节判定器220可以判定在什么位置加多少数量的塑料薄膜。同时，量化调节判定器220还可以有一个可视化的界面来显示智能天线校准板印刷电路的示意图，覆盖塑料薄膜的位置和数量等。这样，用户只要根据如图6所示的可视化界面显示的信息就可以在智能化天线校准板的相应位置覆盖相应数量的塑料薄膜，进而实现量化调节各个天线端口的功率 幅度值和相位值的功能。
