随着当今社会的不断发展，移动通信系统中的终端用户数量急速增长，尤其是在城市地区，用户分布随时间变化大，使得大部分工业区和商业区的基站都负荷会随着每天上下班时间点或者节假日的因素而有着显著落差变化。这样使得基站系统的负荷时常出现利用率低的情况，进而造成通信资源的浪费。
为了能够根据移动通信系统网络的覆盖区域、干扰现象、话务量等状况调整天线的辐射状态，需要移相器对基站天线发射的方向图指向起调节作用，以满足灵活调节覆盖不同用户区域的要求。移相器是能够对波的相位进行调整的一种装置，它是天线的核心组成部分。移相器通过改变到达天线的信号的相位来改变天线的方向图，进而实现对网络覆盖区域进行远程控制的目的。

具体实施方式
以下结合附图和具体实施例对本发明作详细描述。注意，以下结合附图和具体实施例描述的诸方面仅是示例性的，而不应被理解为对本发明的保护范围进行任何限制。
如图1和图2所示，本实施例提供了一种双模式移相装置，包括耦合基板100和微带底板200，耦合基板100上设置有耦合微带线110，微带底板200上设置有第一微带线210和第二微带线220。耦合基板100平行放置于微带底板200上并且二者并不直接接触，耦合基板100和微带底板200之间设置有绝缘介质，使耦合微带线110与第一微带线210和第二微带线220通过电容耦合的方式实现线路连接。
通过耦合基板100与微带底板200之间的相对滑动，可以切换第一工作模式(参见图3)和第二工作模式(参见图4)。其中，第一工作模式为：第 一微带线210与耦合微带线110耦合连接，第二微带线220与耦合微带线110耦合连接；第二工作模式为：第一微带线210与耦合微带线110耦合连接，第二微带线220与耦合微带线110断开连接。
要实现上述功能，需要设计第一微带线210、第二微带线220和耦合微带线110的形状和位置。图1展示了一种实现方式，其中，第一微带线210与第二微带线220平行，第一微带线210和第二微带线220的一端错开，耦合微带线110包括平行设置的第一枝节111和第二枝节112，第一枝节111和第二枝节112的端头平齐，耦合基板100的滑动方向平行于第一微带线210和第二微带线220。
如图4所示，当耦合微带线110从右向左滑动时，存在一个位置，此时第二微带线220会与耦合微带线110断开连接，而第一微带线210仍保持和耦合微带线110的连接，此时就进入了第二工作模式。
需要说明的是，第一微带线210、第二微带线220和耦合微带线110也可以设计为其他形式。例如，第一微带线210和第二微带线220可以设计为两端都平齐，而耦合微带线110的第一枝节111和第二枝节112的端头错开，同样能够实现上述功能。再如，第一微带线210和第二微带线220可以设计为一端错开，耦合微带线110的第一枝节111和第二枝节112的端头也错开，也能够实现上述功能。
上述实施例能够实现第一微带线210与第二微带线220之间通断的切换，换言之，可以控制移相装置的输出口为0或1个。在此基础上，可以增加微带线，设置更多的输出口，从而通过上述结构，可以调节输出口的数量。
例如，在本实施例中，微带底板200上还设置有第三微带线230，第三 微带线230平行于第一微带线220设置。耦合微带线110包括第三枝节113，第三枝节113与第三微带线230始终保持耦合连接。相应地，当处于第一工作模式时，输出口数量为2，当处于第二工作模式时，只有第一微带线210和第三微带线230之间形成通路，输出口数量为1。
此外，本实施例中，耦合微带线110与第一微带线210、第二微带线220部分重叠。当处于第一工作模式时，随着耦合基板100与微带底板200之间的相对滑动，第一微带线210、第二微带线220与耦合微带线110之间的耦合路径发生变化，由此实现相位的改变，实现移相功能。如图3所示，当耦合微带线110从右向左滑动时，从第一微带线210到第二微带线220的总路径增加，输出相位发生滞后。
耦合基板与微带底板之间相对滑动实现移相为移相器中的常见功能，因此相关结构不再赘述。通常微带底板200固定设置于底板300上，所以一般是耦合基板100滑动。
从图3和图4中可以看出，由于第三微带线230与第一微带线210设置于耦合微带线110的两侧，当耦合微带线110滑动时，从第一微带线210到第三微带线230的总物理路径不会发生变化。因此在第一工作模式中，从第一微带线210到第三微带线230的高频信号输出相位保持不变。
在可能的实施例中，耦合微带线110还包括阻抗匹配段114，微带底板200上开设有阻抗匹配槽240。当处于第二工作模式时，阻抗匹配段114与阻抗匹配槽240重合，此时，阻抗匹配段114的基材为空气，其阻抗不同于其他位置，从而确保了切换到第二工作模式时第一微带线210到第三微带线230的信号相位不发生变化。
耦合基板100与微带底板200之间的绝缘介质可以为液态光致阻焊剂(俗称绿油)，也可以采用覆膜工艺实现二者之间的绝缘。耦合基板100可以为单面覆铜板材，微带底板200可以为双面覆铜板材。耦合微带线110、第一微带线210、第二微带线220均可以采用蚀刻方式制成，以利于实现生产自动化，提高生产效率。
综上，本申请实施例所提供的双模式移相装置，可以实现两种工作模式自由切换，一种模式实现一端口输入两端口输出，并且输出相位可调；另一种模式实现一端口输入另一端口输出。
第一工作模式如图3所示，信号从第一微带线210输入，通过耦合微带线110进行一分二信号分配，从第二微带线220和第三微带线230输出。在耦合微带线110由右向左移动的过程中，第一微带线210和第二微带线220与耦合微带线110的耦合路径减小，而第三微带线230与耦合微带线110的耦合路径增加。此时，第一微带线210到第二微带线220的总路径增加，输出相位滞后；第一微带线210到第三微带线230的总路径不变，输出相位同样保持不变。
第二工作模式如图4所示。此时，第二微带线220与耦合微带线110耦合路径消失，第二微带线220呈开路状态且不再作为输出口，仅有第三微带线230仍作为输出口工作，实现“一进一出”工作模式。同时，耦合微带线110中与阻抗匹配槽240同向的阻抗匹配段114与阻抗匹配槽240重合，第一微带线210到第三微带线220的总路径仍与第一工作模式一致，相位不发生变化。
本领域技术人员容易理解地，本申请的另一实施例还提供了一种天线， 包括上述双模式移相装置和天线单元，双模式移相装置与天线单元连接。
