理论上，当PCB板120两面设有完全不相干扰的移相导体121时，该移相器1相当于，以所述PCB板120为分界，所述容置空间11、介质元件13和移相电路12均被分成相对独立的两部分，形成两个能各自独立对流经其中的信号移相的移相器单体。
在其他实施方式中，所述移相导体也可以是金属导体，例如金属条或金属板。所述金属导体根据移相电路的原理组合成所述移相导体，并由介质支撑件固定于所述腔体的容置空间中，参见实施例二。
众所周知，任何传输介质对在其中传导的波动都会引入相移。本发明的移相器1的腔体11内设有可受力沿腔体11纵长方向做直线运动的介质元件13。通过移动该介质元件13，可以改变腔体11内的等效介电常数，从而，改变信号在移相器1中的传播速率，进而，可使流经移相器1的信号形成连续的线性相位差，实现移相的目的。
本发明的介质元件13优选为长条状，其所选用的材料可以是一种或多种，并且该介质元件13的介电常数 ＞1.0。所述介质元件13的材料，除了要求有高介电常数，优选还具有低损耗正切角特性。此外，为了使该移相器1具有较高的等效介电常数，所述容置空间内应尽可能多地由所述介质元件13填充。
如果所述介质元件13与所述移相电路12直接接触，例如所述介质元件13直接置于所述移相电路12上时，除了会使移相电路12受力，还会在操纵介质元件13移动过程中对移相电路12和/或介质元件13造成磨损。
参见图2和图3，为了避免如上问题的出现，本发明的介质移相器1在腔体11内设有至少一个用于在所述介质元件13与所述移相电路12之间形成间隙的导轨14，以避免所述介质元件13和所述移相电路12的直接接触。
所述导轨14呈长条状，设于沿所述腔体11纵长方向的封装壁110内壁上，并沿腔体11的纵长方向延伸。所述导轨14既可以与所述腔体11的封装壁110一体成型，也可在所述腔体11成型后，加工生成于所述腔体11的封装壁110内壁上。
所述介质元件13设有单条时，该条导轨14设于与介质元件13相对的封装壁110内壁上。此处所称与介质元件13相对的封装壁110，是指介质元件13较宽端面所对的封装壁110，也即介质元件13正上方或正下方的封装壁110。所述介质元件13在与所述导轨14相应的位置处设有滑槽139，所述介质元件13以其滑槽139中嵌入所述导轨14的方式与所述导轨14相安装，以供所述介质元件13沿该导轨14做直线运动，并避免所述介质元件13在移动的过程中触碰到所述移相电路12，从而增强该移相器1的可靠性。所述导轨14的截面形状可以为圆形、三角形、矩形、梯形或其他多边形，可由本领域技术人员根据需要设置，下同。
参见图2，所述导轨14设有两个时，所述两个导轨14可以是形状完全相同的一对导轨，该对导轨14分别设于腔体11位于介质元件13两侧的封装壁110的内壁上，并且该对导轨14中的两个导轨被设于两个封装壁110的大致等同的高度处。之所以说两个导轨14被设于两个封装壁110的大致等同的高度处，是由于所述腔体11可能不是严格意义上的长方体，或者由于加工误差导致两个导轨14在腔体11的封装壁110上的高度不能严格相等。然而，应当注意的是，尽管该对导轨14不能做到严格等高设置，还是可以实现本发明的导轨14具有的功能。另外，应当注意的是，此处所称介质元件13两侧的封装壁110，是指该对封装壁与所述介质元件13的厚度方向大体平行，与前述的“与介质元件13相对的封装壁”为相对概念。
为了使容置空间内尽量多地填充介质元件13，所述移相电路12优选安装于该对导轨14之间。如此，则可以在所述移相电路12的上方和下方均设置介质元件13（如上层介质元件130和下层介质元件131），以使本发明的移相器1获得尽量大的等效介电常数。
为了适于所述移相电路12的安装，该对导轨14的每个导轨的厚度应大于所述移相电路12的厚度，以避免被支撑于所述导轨14上的所述介质元件13与所述移相电路12相接触。
所述两个导轨14还可以分别设在移相电路12正上方和移相电路12正下方的封装壁110内壁上。此时，所述导轨14可以参照上述一个导轨的设置方式设置，即，使介质元件13与导轨14通过导轨14嵌于介质元件13的滑槽139相安装。
当所述导轨14在腔体11内设有两个，并且所述两个导轨14分别设于移相电路12正上方和正下方时，它们也可以设为不同的两个。至于在所述腔体11内如何设置所述两个导轨14及所述两个导轨14的形状，具体可参照腔体内只设一个导轨14时的设置，恕不赘述。
参见图3，所述腔体11内可以设置更多导轨14，例如所述导轨14在所述腔体11内设有两对。所述两对导轨14在介质元件13两侧的一对相对的侧壁封装壁110上大致平行设置，并且两对导轨14之间形成一对沿腔体11纵长方向延伸的、用于装设所述移相电路12的卡槽111。所述移相电路12被承载于PCB板之类的基板，所述卡槽111用于夹设移相电路12的基板（即上述介质支撑件120）。如此，则在移相电路12上方和下方各形成一对导轨（如上导轨141和下导轨142）。
与此相应地，所述介质元件13包括设于上导轨141上的上层介质元件130和设于下导轨142下方的下层介质元件131。由于所述两对导轨14的设置，所述介质元件13的活动空间受到了限制，从而避免在介质元件13移动的过程中碰触到所述移相电路12，达到改善交调和提高可靠性的目的。
请结合图1，为了使上层介质元件130和下层介质元件131同步移动，所述介质元件13还包括介质连接元件132。此外，为了使所述介质元件13能受电机（未图示）等外部设备驱动，本发明的移相器1还可以设有与所述介质元件13连接并设于所述腔体11开口端的外力致动元件15。
本领域的技术人员可以推导并将本实施例中的移相电路、介质元件及导轨的相关结构的设置手段应用于后文的其他实施例中。因此，如果下文对本实施例中的个别结构不做具体描述，也并不能说本发明的其他实施方式中的移相器不能具有该结构，应该由本领域技术人员根据需要设置，以能够实现本发明的目的为准。
实施例二
参见图5至图7，本实施例中，所述介质移相器为合成的移相器2，由多个例如两个移相器单体201，202共用一个腔体21组成。
所述腔体21内形成上下并排的两个容置空间，所述容置空间用于安装移相电路22、介质元件23和其他组件，及供所述介质元件23沿腔体21纵长方向做直线运动。两个容置空间中安装相同的移相电路22时，该合成的移相器2工作于同一个频段，适用于单频双极化天线；两个容置空间中装设不同的移相电路22时，该合成的移相器2可工作于不同频段，适用于多频天线。
类似于实施例一，本实施例中，每个所述移相器单体201或202的腔体由多个封装壁210和所述多个封装壁210限定的容置空间构成，所述容置空间内设有移相电路22，所述移相电路22与所述封装壁210之间设有介质元件23。
所述移相电路22包括金属导体220根据移相电路原理组成的移相导体220，和用于将所述金属导体220固定于所述腔体21内的介质支撑件221。所述金属导体220折弯出大致呈U型的形状，包括两个直臂2201和连接两个所述的直臂的基部2202，所述两个直臂2201远离基部2202的端部用于连接传输线缆（未标号），如图5所示。
参见图6，为了防止移相电路22和所述介质元件23直接接触，所述移相电路22与所述介质元件23之间设有用于使移相电路22与介质元件23保持非接触的导轨24。
每个移相器单体201或202的容置空间内均相应设有一对导轨24，所述导轨24以一个大致相等的高度设在所述封装壁210内壁上。所述导轨24的高度大于所述移相电路22的厚度，所述移相电路22设于该对导轨之间，并且所述移相电路22正上方和正下方均设有介质元件23，例如上层介质元件230和下层介质元件231。
为了便于操纵所述介质元件23沿腔体纵长方向做直线运动，所述移相器2还包括与所述介质元件23连接的外力致动元件25。另外，为了保持上层介质元件230和下层介质元件231同步移动，所述介质元件23还设有介质连接元件232。
参见图7，图7为实施例二的另一种移相器的腔体的横截面图。所述介质移相器2由四个移相器单体201、202、203、204通过上下、左右的并排关系组合而成。
所述导轨24在每个移相器单体（如204）内均设有一对，并且该对导轨24设于一对相对的封装壁210内壁大致相同的高度的位置上。
此外，所述的介质元件23和所述的导轨24在每个移相单体中的设置方式，例如所述介质元件和所述导轨的数量、形状、结构和所在位置，可以参照实施例一，此处恕不赘述。
综上所述，本发明通过在移相器的腔体内设置若干导轨，介质元件沿所述导轨相对于腔体和移相电路移动，从而实现对移相器内的信号的调相，由于避免了介质元件与移相电路的直接接触，从而使移相器的电气特性和物理特性均得以大大优化。
虽然上面已经示出了本发明的一些示例性实施例，但是本领域的技术人员将理解，在不脱离本发明的原理或精神的情况下，可以对这些示例性实施例做出改变，本发明的范围由权利要求及其等同物限定。
