请参阅图2及图3，所述移相器100包括腔体10、金属带线20、滑动介质30及固定件40。所述移相器100还包括信号输入端子21及一个或多个间隔设置的信号输出端子22，所述信号输入端子21及所述信号输出端子22设于所述金属带线20延伸方向上的不同位置，并与所述金属带线20电连接。所述金属带线20、所述滑动介质30以及信号输入端子21及信号输出端子22均收容于所述腔体10内。所述金属带线20包括固定部以及与所述固定部连接的传输部，所述固定件40与所述金属带线20的固定部连接，并将金属带线20固定于腔体10内，并使金属带线20的传输部悬置于所述腔体10内，实现金属带线20在腔体10内的稳定的定位，保证移相器100的品质。本实施例中，金属带线20上设有固定件40的区域为所述固定部，所述金属带线20除所述固定部外的其它部分为传输部。所述滑动介质30设于所述金属带线20的表面并可相对所述金属带线20移动，以改变所述信号输入端子21与信号输出端子22之间的传输段上所述滑动介质30覆盖的所述金属带线20的面积，从而使得所述信号输入端子21至所述信号输出端子22之间的传输段内介质的等效介电常数发生改变，从而改变从该所述信号输出端子22输出的信号的功率及相位。其中，“所述信号输入端子21与信号输出端子22之间的传输段”是指信号从所述信号输入端子21传输至信号输出端子22的信号传输路径。
具体的，需要辐射出去的信号通过所述信号输入端子21传输至所述腔体10中，并通过所述腔体10内的介质进行沿所述金属带线20方向传输至所述信号输出端子22。其中，所述腔体10内的介质包括层叠于所述金属带线20表面的滑动介质30以及位于所述金属带线20周围的空气。当所述滑动介质30沿所述金属带线20进行移动时，所述信号输入端子21至所述信号输出端子22之间的传输段内的介质的等效介电常数发生变化，从而使得该信号从所述信号输出端子22传输出来的信号的相位发生变化。例如，所述滑动介质30移动前，所述传输段内的介质仅有金属带线20与腔体10之间的的空气；而当所述滑动介质30移动一定距离后，所述滑动介质30移动至该传输段内，从而使得所述传输段内的介质包括滑动介质30以及该传输段内的所述金属带线20与腔体10之间的空气，从而使得所述传输段内的介质的等效介电常数发生变化，，所述信号输出端子22输出的信号的相位即会发生变化。并且，连续的移动所述滑动介质30时，所述传输段内的滑动介质30的面积不断的变化，即使得所述传输段内的介质的等效介电常数发生变化，最终使得所述信号输出端子22输出的信号的相位能够进行连续的变化。因此，本申请中，能够根据实际需要，移动所述滑动介质30一定的距离，从而使得辐射出去的信号具有所需的相位。
本实施例中，所述移相器具有一个信号输入端子21及五个信号输出端子22，所述信号输入端口21及所述信号输出端口22均位于所述金属带线20的一侧。所述信号输入端子21位于所述金属带线20的中间区域，五个所述信号输出端子22分置于所述 信号输入端子21的两侧。并且，所述信号输入端子21至每个所述信号输出端子22之间的距离均不相同，从而使得从每个所述信号输出端子22输出的信号的相位均不相同。具体的，五个所述信号输出端子22分别为沿所述金属带线20延伸方向依次排列的第一信号输出端子221、第二信号输出端子222、第三信号输出端子223、第四信号输出端子224以及第五信号输出端子225。其中，第一信号输出端子221、第二信号输出端子222、第三信号输出端子223位于所述信号输出端21的一侧，所述第四信号输出端子224以及第五信号输出端子225位于信号输出端21的另一侧。
本申请中，所述金属带线20为金属线或者金属板等金属件加工形成的金属带状结构，金属。通过固定件40将金属带线20固定于腔体10内，使得所述金属带线20的传输部悬置于腔体内，不需要将金属带线设置于基板上，减少了基板对于信号能量的损耗，增大所述电调天线1000的增益。并且，能够减少由于所述信号能量损耗而产生的热量，从而降低所述移相器100对于散热及内部结构件耐热性能的要求，增强所述电调天线1000内各结构的耐温可靠性。本实施例中，所述金属带线20为一体成型结构。可以理解的是，在本申请的其它实施例中，所述金属带线20可以包括沿多个子金属带线20，多个子金属带线20之间射频连接形成所述金属带线20。
进一步的，本申请的一些实施方式中，所述金属带线20的传输部包括一个或者多个间隔设置的波浪线区段23，所述波浪线区段23为金属线或金属板加工形成的波浪形结构。通过将波浪形结构，使得形成所述金属带线20的金属线的长度一定时，尽量缩短移相器100的长度，使得能够实现精细的移相控制的同时，尽量减小移相器100的体积，便于移相器100与其它结构进行集成。

其中，所述第二固定件42的第一部分411及所述第二部分412可以为一体成型结构；或者，所述第二固定件42的第一部分411及所述第二部分412也可以为分开的两个部分，所述第一部分411与所述第二部分412之间固定连接以将所述金属带线20夹紧于所述第一部分411与所述第二部分412之间。

所述滑动介质30的长度小于所述金属带线20的长度，当相对所述金属带线20移动所述滑动介质30时，使得位于金属导线20两端的输出信号端子22的相位同时发生改变。例如，当向所述第一信号输出端子221方向移动所述滑动介质30时，所述信号输入端子21与所述第一信号输出端子221之间的传输段，所述滑动介质30覆盖所述金属带线20的面积增加，从而使得该传输段内的介质的等效介电常数增加；此时，所述信号输入端子21至所述第五信号输出端子225之间的传输段，所述滑动介质30覆盖所述金属带线20的面积会减小，从而使得该传输段内的介质的等效介电常数降低，从而使得所述第一信号输出端子221与第五信号输出端子225的相位同时发生变化。
请再次参阅图3及图6，本申请一种实施方式中，所述滑动介质30包括第一区段30a、第二区段30b及连接所述第一区段30a及所述第二区段30b的连接区段30c，所述第一区段30a与第二区段30b在垂直于金属带线20的延伸方向上错开。本实施例中，所述第一区段30a与第二区段30b及所述连接区段30c连接形成Z字型结构。所述金属带线20包括第一区段20a、第二区段20b及连接所述第一区段20a及所述第二区段20b的连接区段20c，所述第一区段20a与第二区段20b在垂直于金属带线20的延伸方向上错开。本实施例中，所述第一区段20a、第二区段20b及所述连接区段20c连接形成Z字型结构。所述滑动介质30的第一区段30a层叠于所述金属带线20的第一区段20a上并相对所述第一区段30a移动，所述滑动介质30的第二区段30b层叠于所述金属带线的第二区段20b上并相对所述滑动介质的第二区段30b移动。
所述第二固定件42为两个或两个以上，在垂直于所述金属带线20延伸方向上，其中一个所述第二固定件42与所述滑动介质的第一区段30a位于所述滑动介质的第二区段30b的同侧，所述第二固定件42设置在所述滑动介质的第一区段30a的滑动方向上，以限定所述滑动介质相对所述金属带线20的行程。具体的，所述第二固定件42可以位于所述第一区段30a的行程方向上远离所述第二区段30b的一侧，或者，位于所述第一区段30a的行程方向上靠近所述第二区段30b的一侧。同样的，另一个所述第二固定件42与所述滑动介质30的第二区段30b位于所述滑动介质30的第一区段30a的同侧，所述第二固定件42设置在所述滑动介质30的第二区段30b的滑动方向上，以限定所述滑动介质30相对所述金属带线20的行程。具体的，所述第二固定件42可以位于所述第二区段30b的行程方向上远离所述第一区段30a的一侧，或者，位于所述第二区段30b的行程方向上靠近所述第一区段30a的一侧。
具体的，本实施例中，所述滑动介质30的第一区段30a包括上端面31及与上端面31相平行的下端面32，所述第二区段30b均包括上端面33及与所述上端面33平行的下端面34。所述第一区段30a及所述第二区段30b的上端面均位于所述下端面的同一侧。换句话说，所述上端面31位于所述下端面32的上方时，所述上端面33也同样位于所述下端面34的上方。其中一个所述第二固定件42设于所述金属带线20的第一区段20a，且该所述第二固定件42的外表面与所述滑动介质30的第一区段30a的下表面32接触。并且，该所述第二固定件42沿所述第一区段30a的下表面32移动，其移动区间为所述连接区段30c至所述第一区段30a的远离所述第二区段30b的一端；另一个所述第二固定件42设于所述金属带线20的第二区段20b，且该所述第二固定 件42的外表面与所述滑动介质30的第二区段30b的上表面33接触，该所述第二固定件42沿所述第二区段30b的上表面33移动，其移动区间为所述连接区段30c至所述第二区段30b远离所述第一区段30a的一端。
本实施方式的所述移相器100，所述滑动介质30相对所述金属带线20时，其相对于所述金属带线20的移动距离会受到所述第二固定件42的限制，从而防止所述滑动介质30从所述金属带线20表面脱离而不能调节相位，即保证所述金属带线20与所述滑动介质30在垂直于所述金属带线20方向至少有部分重合，并能够改变所述滑动介质30在所述金属带线20上的覆盖面积，以改变输出信号的相位。例如，当所述滑动介质30向所述第一信号输出端口221方向移动时，移动至一定位置后，沿所述第一区段30a的下表面32相对移动的第二固定件42移动至所述连接区段30c而被所述连接区段30c挡住，从而避免所述滑动介质30进一步的向所述第一信号输出端口221方向移动而与金属导线20脱离；同样的，当所述滑动介质30向所述第五信号输出端口225方向移动时，移动至一定位置后，沿所述第二区段30b的上表面33相对移动的第二固定件42移动至所述连接区段30c而被所述连接区段30c挡住，从而避免所述滑动介质30进一步的向所述第五信号输出端口225方向移动而与金属导线20脱离。
