具体实施方式Detailed ways
阵列天线是多个辐射单元按一定规律排列组成的天线。多频阵列天线是由支持不同工作频段的多个阵列天线共同组成的一个天线集合。多频阵列天线的尺寸通常是由反射板的大小决定的，而反射板的大小又是由该多频阵列天线中所有辐射单元在反射板上所占的区域的大小决定的。如图1所示，其为一种传统的多频阵列天线的结构示意图，该多频阵列天线包括空气基板(空气基板是由空气层构成的一种介质基板，介电常数为1)、反射板101、工作频段为2.4吉赫兹(英文：gigahertz)频段的微带天线102和工作频段为5GHz频段的微带天线103。这两种微带天线分别包括各自的辐射单元及各自的馈电网络，其中，馈电网络与辐射单元之间的连接点为馈电口。反射板101上的多个辐射单元可以通过绝缘支架架在反射板101上方，这多个辐射单元和反射板101之间为空气基板。微带天线102的辐射单元以及微带天线103的辐射单元在反射板101上均单独分离排布。由图1可以看出，微带天线102的辐射单元以及微带天线103的辐射单元在反射板101上占用了较大的区域，这致使反射板101的尺寸较大，因而多频阵列天线的尺寸较大。其中，微带天线(英文：microstripantenna)是在介质基板一侧贴加辐射单元，另一侧设置反射板而形成的天线。反射板为导体接地板(英文：ground plane)。介质基板使辐射单元和反射板之间开路。辐射单元和反射板之间的开路产生电磁波。辐射单元为微带天线的基本结构单元，它能有效地辐射或接收电磁波。工作频段为微带天线工作的频率范围。馈电网络为多个辐射单元的天线馈电线(英文：antenna feed line)构成的线路网络。An array antenna is an antenna composed of multiple radiating elements arranged according to a certain rule. A multi-frequency array antenna is an antenna set composed of multiple array antennas supporting different operating frequency bands. The size of the multi-frequency array antenna is usually determined by the size of the reflector, and the size of the reflector is determined by the size of the area occupied by all the radiating elements in the multi-frequency array antenna on the reflector. As shown in FIG. 1, it is a schematic diagram of the structure of a traditional multi-frequency array antenna. The multi-frequency array antenna includes an air substrate (an air substrate is a dielectric substrate composed of an air layer with a dielectric constant of 1), a reflection The
多频天线可以由一个辐射组件或者多个辐射组件呈阵列排布构成。其中，每一辐射组件包括至少两个具有不同工作频段的辐射单元。当多频天线由多个辐射组件呈阵列排布构成时，所述多频天线为多频阵列天线。本申请以由一个辐射组件构成的多频天线为例进行说明。The multi-frequency antenna can be composed of one radiating element or a plurality of radiating elements arranged in an array. Wherein, each radiation component includes at least two radiation units with different working frequency bands. When the multi-frequency antenna is composed of a plurality of radiating components arranged in an array, the multi-frequency antenna is a multi-frequency array antenna. In this application, a multi-frequency antenna composed of one radiating element is used as an example for description.

进一步地，所述第二导线可以从所述第一辐射单元111的内部区域的中心穿过所述第一辐射单元111。由于所述第一辐射单元111的辐射能量由其内部区域靠近周边的位置向内部区域的中心逐渐递减。因此，所述第二导线穿过所述第一辐射单元111的内部区域的中心，则所述第二辐射单元211的信号与所述第一辐射单元111之间更加没有干扰。Further, the second wire may pass through the
进一步地，所述第二导线包括第三段及第四段，所述第三段平行于所述第一辐射单元111，所述第四连接段垂直于所述第一辐射单元111。所述第三段的一端连接所述第二辐射单元211的另一馈电口2112，所述第三段的另一端连接所述第四段的一端，所述第四段的另一端连接所述收发器件，所述第四段从所述第一辐射单元111的内部区域穿过所述第一辐射单元111。所述第一导线341及第二导线的线路网络为馈电网络。Further, the second wire includes a third segment and a fourth segment, the third segment is parallel to the
在本实施例中，所述线路板包括第一子板351及第二子板352。所述第一子板351与所述第二子板352垂直，且所述第一子板351与所述第二子板352的相交线与所述第一辐射单元111。所述第一导线341位于所述第一子板351内，所述第二导线位于所述第二子板352内。In this embodiment, the circuit board includes a
所述第一子板351与所述第二子板352垂直设置，所述第一导线341设置于所述第一子板351。所述第二导线设置于所述第二子板352内，使得所述第一导线341与所述第二导线更便于垂直，进而使得所述馈电口2111与所述另一馈电口2112的信号可以垂直正交极化，这样设置的目的是方便后续对所述馈电口2111与所述另一馈电口2112的信号进行质量分析时简化计算分析过程。其中，所述第一子板351与所述第二子板352的相交线为所述第一子板351及所述第二子板352之间的公共线。The
其中，由于第一辐射单元111直接设置于所述反射板30上方，不需经过任何辐射单元，无需考虑第一辐射单元111的馈电口2111的信号对其他辐射单元性能的影响，故所述第一辐射单元111的馈电口2111与收发器件的连接可以采用传统的连接方式即可。故在此不再赘述。Wherein, since the
请参阅图5，本发明第二方案实施例还提供一种通信系统400。所述通信系统400包括基站410及多频天线。所述基站410用所述多频天线收发信号。所述多频天线可以为上述第一方案第一实施例提供的所述多频天线100。由于所述多频天线100已经在上述第一方案中进行了详细的描述，故在此不再赘述。在其他实施例中，所述多频天线也可以为上述第一方案第二实施例中提供的多频天线200。Referring to FIG. 5 , an embodiment of the second solution of the present invention further provides a
需要说明的是，所述基站410可以指无线电收发机，例如蜂窝网络中的蜂窝设置点(英文：cell site)，无线局域网(英文：wireless local area network；简称：WLAN)中的无线接入点(英文：wireless access point；简称：WAP)。It should be noted that the
在本实施例中，所述通信系统400包括所述多频天线100。所述多频天线100包括反射板30及设置于所述反射板上方的辐射组件1001，所述辐射组件1001包括第一辐射单元111及第二辐射单元211，所述第一辐射单元111及所述第二辐射单元211的工作频段不同。其中，所述第一辐射单元111的尺寸大于所述第二辐射单元211的尺寸，所述第二辐射单元211在所述第一辐射单元111的上方，所述第二辐射单元211在所述第一辐射单元111上的投影完全在所述第一辐射单元111之内。因此，所述第一辐射单元111与所述第二辐射单元211重叠。反射板30上的第一及第二辐射单元111及211在反射板21上所占的区域的面积小于传统的多频天线中辐射单元在反射板上所占的面积，进而本发明实施例中的反射板30的尺寸也可以缩小，多频天线100的尺寸缩小。另外，所述第二辐射单元211在所述第一辐射单元111上的投影完全在所述第一辐射单元111之内，由于所述第一辐射单元111的周边较大的辐射能量，所述第一辐射单元111除了周边之外的内部区域内几乎没有辐射能量，因此，所述第二辐射单元211对所述第一辐射单元111的信号辐射几乎没有影响，或者影响甚微。所述第一辐射单元111及所述第二辐射单元211的性能得以维持。综上所述，本申请实施例提供的多频天线100在缩小其尺寸的同时仍然可以维持各自性能。In this embodiment, the
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。What is disclosed above is only the preferred embodiment of the present invention, of course, it cannot limit the scope of the right of the present invention.
