Description

移相器、天线和无线通信设备 技术领域
本发明实施例涉及通信领域，尤其涉及移相器、天线和无线通信设备。
背景技术
随着移动通信应用日益广泛，人们对通信容量和质量都提出了更高的要求。下倾角可调的电调天线可以实现良好的覆盖，并且减少小区之间的干扰。移相器作为电调天线的一个重要部件，其相位调节范围对驻波匹配的效果有着较大的影响。另一方面，随着基站射频系统中天线端口数不断增加，移相器的小型化需求也越来越迫切。
移相器通过调节输入端口到输出端口的信号传递长度改变输出端口的输出相位。在现有技术中，为了提高移相器的电性能，扩大相位调节范围，往往需要使得输入端口到输出端口的信号传递长度可以在较大范围内进行增加或减少，从而增加移相器的尺寸。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，可以理解的是，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1为本发明一实施例提供的移相器的结构纵向剖面示意图，如图1所示，移相器包括：腔体101，转轴102，主印刷电路板(printed circuit board，PCB)103，第一滑动件104A以及第二滑动件104B。其中，腔体101用于组成移相器的带状线的上下地层。在腔体101中，第一滑动件104A和第二滑动件104B分别位于主PCB 103的正面和背面，与主PCB 103耦合连接。例如，如图1所示，主PCB103 向上的一面为正面，则相应地向下的一面为背面，则第一滑动件104A在主PCB 103的上面，第二滑动件104B在主PCB 103的下面。主PCB 103可以采用多种方式与第一滑动件104A、第二滑动件104B形成耦合连接，例如，采用绝缘膜，涂覆料等，第一滑动件104A以及第二滑动件104B可以是PCB或者金属件，本发明实施例并不限于此。主PCB 103、第一滑动PCB 104A以及第二滑动PCB 104B均居于腔体101中，使得移相器的信号带线与腔体101之间无接触点，形成带状线分布。
转轴102插入腔体101，与第一滑动件104A、第二滑动件104B分别连接，以带动第一滑动件104A、第二滑动件104B相对于主PCB 103转动。在一种实现方式中，转轴102通过穿孔插入腔体101，从上至下依次穿过第一滑动件104A，主PCB 103以及第二滑动件104B，第一滑动件104A和第二滑动件104B分别紧固在转轴102上，从而转轴102转动时，带动第一滑动件104A和第二滑动件104B相对于主PCB 103转动。需要说明的是，此处仅是举例，本发明实施例并不限于此。
参见图2，为本发明另一实施例提供的移相器的结构内部分解示意图，如图所示：主PCB 103包括主信号线103-1，主中心耦合段103-3，第一圆弧状相位延迟线103-4以及第二圆弧状相位延迟线103-5。
其中，主信号线103-1具有输入端口Pin，用于接收输入信号，并与主中心耦合段103-3连接，主中心耦合段103-3靠近转轴102，部署于主PCB 103的基材的两侧，主中心耦合段103-3在主PCB 103的基材的两侧的电路是相互连通的，如图4所示。主中心耦合段103-3可以是以转轴102的中心为圆心部署，这里主中心耦合段103-3可以是圆环状，环绕转轴102，也可以是以转轴102为圆心的一段圆弧。主中心耦合段103-3也可以是在转轴102附近的其他形状的耦合段。需要说明的是，此处仅为举例，本发明不限于此。
第一圆弧状相位延迟线103-4和第二圆弧状相位延迟线103-5以转轴102的中心为圆心分布，并且位于主中心耦合段103-3的外侧。第一圆弧状相位延迟线103-4具有两个输出端口P2和P4，第二圆弧状相位延迟线103-5 具有两个输出端口P1和P5。
第一滑动件104A，具有第一副中心耦合段104A-1、第一传输段104A-2和第一延迟线耦合段104A-3。
第一副中心耦合段104A-1靠近转轴102，与主中心耦合段103-3耦合连接，例如，第一副中心耦合段104A-1可以是以转轴102的中心为圆心部署，这里第一副中心耦合段104A-1可以是圆环状，环绕转轴102，也可以是以转轴102为圆心的一段圆弧。第一副中心耦合段104A-1也可以是在转轴102附近的其他形状的耦合段。需要说明的是，此处仅为举例说明，本发明实施例并不限于此。由于主PCB 103和第一滑动件104A耦合连接，主中心耦合段103-3和第一副中心耦合段104A-1均靠近转轴，其部署的位置保证两者也能耦合连接。第一副中心耦合段104A-1和第一延迟线耦合段104A-3之间通过第一传输段104A-2连接，以使得第一延迟线耦合段104A-3和第一圆弧状相位延迟线103-4耦合连接，从而保证信号可以通过第一延迟线耦合段104A-3耦合传递到第一圆弧状相位延迟线103-4。例如，第一副中心耦合段104A-1和第一延迟线耦合段104A-3分别位于第一传输段104A-2的两端，第一传输段104A-2可以是直线段形状，也可以是其他折线段或者曲线段形状，两端之间的直线距离使得第一延迟线耦合段104A-3和第一圆弧状相位延迟线103-4耦合连接即可，在本发明的一个实施例中，第一圆弧状相位延迟线103-4和第一副中心耦合段104A-1之间的半径差与第一传输段104A-2的两端之间的直线距离相匹配。需要说明的是，此处均为举例，并不限于此。从而第一滑动件104A可以用于将信号耦合传递到第一圆弧状相位延迟线103-4。
第二滑动件104B，具有第二副中心耦合段104B-1、第二传输段104B-2和第二延迟线耦合段104B-3。
第二副中心耦合段104B-1靠近转轴102，与主中心耦合段103-3耦合连接，其实现方式与第一副中心耦合段104A-1类似，此处不再赘述。由于主PCB 103和第二滑动件104B耦合连接，主中心耦合段103-3和第二副中心耦合段104B-1 均靠近转轴，其部署的位置保证两者也能耦合连接。第二副中心耦合段104B-1和第二延迟线耦合段104B-3之间通过第二传输段104B-2连接，以使得第二延迟线耦合段104B-3和第二圆弧状相位延迟线103-5耦合连接，从而保证信号可以通过第二延迟线耦合段104B-3耦合传递到第二圆弧状相位延迟线103-5。第二滑动件104B与第一滑动件104A的实现方式类似，可参见前述对第一滑动件104A各部件的描述，此处不再赘述，所不同的是第二滑动件104B中的第二延迟线耦合段104B-3是与第二圆弧状相位延迟线103-5耦合连接，第二滑动件104B用于将信号耦合传递到第二圆弧状相位延迟线103-5。
信号从输入端口Pin输入，经由主信号线103-1传递到主耦合段103-3，信号一分为二，分别通过第一滑动件104A和第二滑动件104B耦合传递到第一圆弧状相位延迟线103-4和第二圆弧状相位延迟线103-5。以第一滑动件104A为例，一分为二的其中一路信号耦合传递到与主耦合段103-3耦合连接的第一副中心耦合段104A-1，并经由第一传输段104A-2传递到第一延迟线耦合段104A-3，再耦合传递到与第一延迟线耦合段104A-3耦合连接的第一圆弧状相位延迟线103-4。通过第二滑动件104B传递的另一路信号的传递方式与之类似，此处不再赘述。
当转轴102带动第一滑动件104A和第二滑动件104B相对主PCB 103转动时，输入端口Pin到各输出端口的信号传递长度发生改变，从而各输出端口输出信号的相位相应增加或减小。以第一圆弧状相位延迟线的两个输出口为例说明，如图3所示，当第一滑动件104A从左往右，如角度1转动到角度2时，Pin到P1的信号传递长度增加，Pin到P5的信号传递长度减小，从而P1输出信号的相位减少，P5输出信号的相位增加。
本发明实施例提供的移相器，相比于现有移相器，在相同尺寸，相同输出端口的条件下，由于两个滑动件都是从圆心将信号分别耦合传递到两个圆弧状相位延迟线，两个圆弧状相位延迟线分别有各自对应的传输段，各传输段的长度相比于现有移相器更长，从而更容易进行驻波匹配；此外移相器的输入端口到输出端口的信号传递长度的调节范围也得以增加，扩大了移相器的相 位调节范围，提高了移相器的电性能。
可选地，主PCB 103还可以包括零相位线103-2，零相位线103-2与主信号线连接，其输出端口P3的相位输出恒定，用于输出零相位，可以和其他各输出端口的输出相位形成等差相位。例如，P3相位为0，通过转动转轴102调节，使得P1、P2、P3、P4和P5输出的相位分别为-2Φ，-1Φ，0，1Φ，2Φ，其中Φ为相位角。
图4为本发明另一实施例提供的采用超慢波结构的圆弧状相位延迟线的结构示意图，图5为本发明另一实施例中提供的采用常规结构的圆弧状相位延迟线的结构示意图。如图4、图5所示，以转轴202的中心为圆心，圆弧状相位延迟线以转轴202的中心为圆心分布。参见图4，采用超慢波结构的圆弧状相位延迟线203-4呈蛇形，蛇形缝隙的深度为l1，其相对于转轴202的轴心的半径为r1，该圆弧状相位延迟线内径和外径的差值，也就是宽度为d1。参见图5，采用常规结构的圆弧状相位延迟线203-5，其相对于转轴202的轴心的半径为r2，该圆弧状相位延迟线内径和外径的差值，也就是圆弧状相位延迟线的宽度为d2。采用超慢波结构的相位延迟线总体上呈蛇形，在相同阻抗下，采用超慢波结构的圆弧状相位线的宽度d1一般大于采用常规结构的圆弧状相位延迟线d2，例如，d1大于两倍的d2，蛇形缝隙的深度l1可以取值为0.6～0.9倍的d1。需要说明的是，此处仅为举例，本发明实施例并不限于此。
在图4和图5中，滑动件204具有副中心耦合段204-1，传输段204-2以及延迟线耦合段204-3，将信号从转轴202附近的主耦合段203-3耦合到圆弧状相位延迟线输出到输出口。当r1＝r2时，图4和图5中角度1是相同的，图4和图5中角度2也是相同的，滑动件204沿着轴心从角度1摆动到角度2时，采用超慢波结构的圆弧状相位延迟线203-4的输出口P1的相位变化如图6所示，采用常规结构的圆弧状相位延迟线203-5的输出口P2的相位变化如图7所示。其中，纵轴均为相位，单位为度，横轴均为频率，单位为GHz。例如，在频率为2.2GHz时，采用超慢波结构的圆弧状相位延迟线203-4在角度1的输出相位为 -64.3344度，在角度2的输出相位为-296.0942度，而采用常规结构的圆弧状相位延迟线203-5在角度1的输出相位为-45.6899度，在角度2的输出相位为-145.1370。从图6和图7的数据可以看出，在相同频率，相同角度下，采用超慢波结构的圆弧状相位延迟线的输出的相位小于采用常规结构的圆弧状相位延迟线的输出相位。在滑动件204从角度1摆动到角度2时，对比两个圆弧状相位延迟线的移相量，这里的移相量也就是角度1和角度2的输出相位之差的绝对值，其含义可以表示相位的调节范围，则采用超慢波结构的圆弧状相位延迟线203-4的移相量为231.6487度，采用常规结构的圆弧状相位延迟线203-5的移相量为99.4471度。可见采用超慢波结构的圆弧状相位延迟线的相位的调节范围要远大于采用常规结构的圆弧状相位延迟线。需要说明的是，此处各数据均只是举例，本发明实施例并不限于此。
在本发明一个实施例中，第一圆弧状相位延迟线和第二圆弧状相位延迟线中至少有一个为采用超慢波结构的圆弧状相位延迟线。如图2所示，第一圆弧状相位延迟线103-4为采用常规结构的圆弧状相位延迟线，第二圆弧状相位延迟线103-5为采用超慢波结构的圆弧状相位延迟线。也可以是，第一圆弧状相位延迟线103-4为采用超慢波结构的圆弧状状相位延迟线，第二圆弧状相位延迟线为采用常规结构的圆弧状相位延迟线，或者两者皆为采用超慢波结构的圆弧状相位延迟线。需要说明的是，这里只是举例说明，本发明实施例并不限于此。由于在相同半径下，也就是相同尺寸的条件下，采用超慢波结构的相位延迟线的移相量相比采用常规结构的相位延迟线的移相量可以提升一倍以上，从而可以进一步将移相器的相位调节范围提升一倍以上。
图8为本发明另一实施例提供的移相器的外部结构图，该移相器为集总式6端口移相器，图9为该实施例提供的移相器的主PCB正面一侧内部结构的平面示意图，图10为该实施例提供的移相器的位于主PCB背面一侧内部结构的平面示意图。参见图9～10，该移相器40包括：腔体401，转轴402，主PCB403，第一滑动件404A和第二滑动件404B。
主PCB403其正面和背面分别与第一滑动件404A和第二滑动件404B耦合连接，被卡入腔体401的槽孔中，使得移相器的信号带线与腔体401之间无接触点，形成带状线分布。
转轴402插入腔体401，与第一滑动件404A、第二滑动件404B分别连接，以带动第一滑动件404A、第二滑动件404B相对于主PCB403转动。
主PCB 403包括主信号线403-1，零相位线403-2，主中心耦合段，第一圆弧状相位延迟线403-4以及第二圆弧状相位延迟线403-5。主信号线403-1具有输入端口Pin，用于接收输入信号，并与主中心耦合段连接。第一圆弧状相位延迟线403-4和第二圆弧状相位延迟线403-5以转轴402的中心为圆心分布，位于主中心耦合段的外侧，且位于转轴402的同一侧。第一圆弧状相位延迟线403-4具有两个输出端口P1和P5，第二圆弧状相位延迟线403-5具有两个输出端口P2和P4。零相位线403-2与主信号线403-1连接，具有输出端口P3。
第一滑动件404A包括第一副中心耦合段404A-1、第一传输段404A-2和第一延迟线耦合段404A-3。第一滑动件404A用于将信号耦合传递到第一圆弧状相位延迟线403-4。
第二滑动件404B包括第二副中心耦合段404B-1、第二传输段404B-2和第二延迟线耦合段404B-3。第二滑动件404B用于将信号耦合传递到第二圆弧状相位延迟线403-5。
该移相器40还可以包括同轴线412，用于与各输入端口和输出端口电连接输出信号，以便连接辐射单元，使得信号能有效输出产生方向图。
当信号从Pin输入，一部分能量经由零相位线403-2的输出口P3输出，形成零相位，另一部分能量通过主中心耦合段一分为二，分别通过第一滑动件404A和第二滑动件404B耦合传递到第一圆弧状相位延迟线403-4和第二圆弧状相位延迟线403-5，从各输出端口P1、P2、P4和P5输出。
第一滑动件404A和第二滑动件404B被转轴402带动绕转轴402中心转动时，从输入端口Pin到达不同输出端口P1，P2，P4和P5的信号传递长度发生变 化，改变了上述输出端口的相位值，从而产生移相作用。
需要说明的是，本发明实施例的结构和连接方式可参见前述实施例的相关记载，其实现原理和技术效果类似，在此不再赘述。
本发明实施例提供的移相器，相比于现有移相器，在相同尺寸，相同输出端口的条件下，由于两个滑动件都是从圆心将信号分别耦合传递到两个圆弧状相位延迟线，两个圆弧状相位延迟线分别有各自对应的传输段，各传输段的长度相比于现有移相器更长，从而更容易进行驻波匹配；此外移相器的输入端口到输出端口的信号传递长度的调节范围也得以增加，扩大了移相器的相位调节范围，提高了移相器的电性能。
进一步地，为了增加输出端口，基于上述实施例，移相器的主PCB上还可以增加部署圆弧状相位延迟线，每个圆弧状相位延迟线均具有两个输出端口。为了使信号从转轴的中心耦合传递到各圆弧状相位延迟线，各圆弧状相位延迟线可以转轴的中心为圆心分布在同侧或者两侧。相应地在第一滑动件或者第二滑动件上需要增加副中心耦合段，传输段以及延迟线耦合段，用于将信号从圆心耦合传递到新增加的圆弧状相位延迟线输出。
图11为本发明另一实施例提供的移相器的外部结构图，该移相器具有8端口，图12为该实施例提供的移相器的主PCB正面一侧的内部结构的平面示意图。该移相器的主PCB背面一侧的内部结构的平面示意图可以参考前述实施例，此处不赘述。参见图11～12，该移相器50包括：腔体501，转轴502，主PCB503，第一滑动件504A和第二滑动件504B。主PCB503包括主信号线503-1，零相位线503-2，主中心耦合段，第一圆弧状相位延迟线503-4以及第二圆弧状相位延迟线503-5。第一滑动件504A包括第一副中心耦合段504A-1、第一传输段504A-2和第一延迟线耦合段504A-3。第一滑动件504A用于将信号耦合传递到第一圆弧状相位延迟线503-4。第二滑动件504B包括第二副中心耦合段、第二传输段和第二延迟线耦合段。第二滑动件504B用于将信号耦合传递到第二圆弧状相位延迟线503-5。其中第二圆弧状相位延迟线503-5和第二滑动件504B位于主PCB背 面，其结构和部署可以参见前述实施例，此处不再赘述。
主PCB503还包括了第三圆弧状相位延迟线503-6，第三圆弧状相位延迟线503-6以转轴502的中心为圆心分布，位于主中心耦合段的外侧，且相对于第一圆弧状相位延迟线503-3分布在转轴502的另一侧，其半径可以与第一圆弧状相位延迟线503-4的半径相同，也可以与第一圆弧状相位延迟线503-4的半径不同。第三圆弧状相位延迟线503-6可以采用超慢波结构，也可以采用常规结构。需要说明的是，此处仅为举例，本发明实施例并不限于此。第三圆弧状相位延迟线503-6具有两个输出端口。
相应地，第一滑动件504A还包括第三副中心耦合段504A-4，第三传输段504A-5和第三延迟线耦合段504A-6。第三副中心耦合段504A-4靠近转轴502，与主中心耦合段耦合连接，可以是圆环状环绕转轴502，也可以是以转轴502为圆心的一段圆弧。第三副中心耦合段504A-4也可以是在转轴502附近的其他形状的耦合段。进一步地，第三副中心耦合段504A-4可以和第一副中心耦合段504A-1连接成为一个副中心耦合段，也可以和第一副中心耦合段504A-1分离开来。需要说明的是，此处仅为举例说明，本发明实施例并不限于此。
第三副中心耦合段504A-4和第三延迟线耦合段504A-6之间通过第三传输段504A-5连接，以使得第三延迟线耦合段504A-6和第三圆弧状相位延迟线503-6耦合连接，从而保证信号可以通过第三延迟线耦合段504A-6耦合传递到第三圆弧状相位延迟线503-6。
该移相器50还可以包括同轴线512，用于与各输入端口和输出端口电连接输出信号，以便连接辐射单元，使得信号能有效输出产生方向图。
需要说明的是，本发明实施例的结构和连接方式可参见前述实施例的相关记载，其实现原理和技术效果类似，在此不再赘述。
本发明实施例提供的移相器，不仅具有前述实施例移相器的优点，并且由于在转轴的另一侧增加部署圆弧状相位延迟线，从而移相器的输出端口在前述实施例的基础上也得到了增加。
本发明实施例还提供了一种天线，本实施例所示的天线所包括的移相器请参见上述所示，具体在本实施例中不做赘述。该天线可以用于无线通信设备。
相应地，本发明实施例还提供了一种无线通信设备，本实施例所述的无线通信设备所包括的天线参见上述实施例。
本发明实施例还提供了一种无线通信设备，本实施例所述的无线通信设备所包括的移相器参见上述所示，具体在本实施例中不做赘述。
这里的无线通信设备可以是基站，也可以是终端设备。本发明实施例并不限于此。
在本申请所提供的几个实施例中，应该理解到，所揭露的设备和方法，可以通过其它的方式实现。例如，以上所描述的设备实施例仅仅是示意性的。
通过以上的实施方式的描述，所属领域的技术人员可以清楚地了解到本发明可以用硬件实现，或固件实现，或它们的组合方式来实现。
总之，以上所述仅为本发明技术方案的较佳实施例而已，并非用于限定本发明的保护范围。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
