Description

一种微波毫米波双频天线
本申请要求在2015年08月21日提交中国专利局、申请号为201510520920.0、发明名称为“一种微波毫米波双频天线”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及天线领域，尤其是涉及一种微波毫米波双频天线。
背景技术
微带天线由于厚度小、易于集成，且成本低，加工制作容易，在微波毫米波领域得到了大量应用。
随着通信技术的不断发展，对双频段微带天线的应用需求不断增大，特别是随着微波毫米波技术在无线通信高速数据回传业务中的应用，需要实现多个数据结点之间的点对点通信，希望天线波束能够在空间实现全向扫描，因此，需要设计毫米波与微波频段的双频全向扫描天线。
现有的一种采用圆周电扫描的全向微带天线，包括上安装盘、反射板、微带天线、支撑柱、天线罩、下安装盘、底封板、电子开关，反射板共8件，通过上安装盘、下安装盘和底封板围成正八面体，微带天线共8件，通过支撑柱安装在反射板围成的正八面体外侧，每块微带天线与对应的反射板间距为λ/4。反射板表面光洁度很高，可以将微带天线向内辐射的能量全部向外反射。天线罩设置在微带天线外侧，电子开关安装在下安装盘上，电子开关通过同轴电缆线与8个微带天线相连接，使8个微带天线中的每相邻两微带天线在3dB相交，形成8个双波束分时按序轮流工作，向外辐射发射能量，并接收目标回波信号能量，实现天线360°圆周扫描。
该技术方案中，8个微带天线中的每相邻两个微带天线在3dB相交，每个微带天线波束宽度达到45度，天线在单个方向上的增益低，不利于远距离 通信。同时，每个微带天线不带有扫描功能，微带天线在±22.5度范围内实现3dB覆盖，使天线抗干扰能力弱。另外，该天线工作在单一频段。
现有的另一种毫米波360°全向扫描介质柱透镜天线，包括三个介质柱透镜、三个扫描范围分别为120°的馈源天线阵列和四个金属圆盘；四个金属圆盘间分别同轴安装有一个介质柱透镜，相邻两个金属圆盘边缘中间处分别安装一个所述馈源天线阵列，所述三个馈源天线阵列在水平投影面上两两相差120°，所述每一个馈源天线阵列的相位中心平面与各自的介质柱透镜的焦平面重合。天线在水平方向实现了360°全向扫描；三个介质柱透镜天线之间有金属圆盘形平行板相隔，各个均匀介质柱透镜的扫描不受其它两个透镜的干扰，因此每层柱透镜天线的扫描波束完全一致；可以方便地与印刷集成电路连接。
该技术方案中，采用介质柱透镜作为天线主体，使天线重量大。同时，天线扫描时，每一个扫描波束对应着馈源天线阵列上的一个单元，当需要的扫描波束较多时，馈源天线阵列的单元数多，馈电网络复杂。另外，该天线也仅工作在毫米波频段。

在上述实施例中，通过采用毫米波辐射阵列13及微波辐射阵列11增强了天线的频段选择，扩大了微波毫米波双频天线的工作频段的选择。
为了方便对本发明实施例提供的天线的结构及工作原理，下面结合具体的附图以及实施例对其进行详细的说明。
如图1所示，为了本发明实施例提供的天线的设置，在本实施例中提供了一个支撑座4，如图1所示，所述多个双频子阵列天线1环绕设置在所述支撑座4的侧面并围成所述正多边形柱体形状，所述毫米波馈电网络3及微波馈电网络2分别设置在所述支撑座4的两个端面。在具体选择时，支撑座4 可以选择不同的形状，如：圆形柱、正多边形柱体等。
继续参考图1，本实施例提供的支撑座4为正多边形柱体，该正多变形柱体为直棱柱，且直棱柱的端面为正多边形，且该正多边形的边数可以根据需要而定，如8、16、64个等。为了方便描述，本实施例中的正多边形柱体的端面为正八边形，即该正多边形柱体为正八边形柱体。该天线包括设置在正八边形柱体的每个侧面的双频子阵列天线1、分别设置在两个端面的微波馈电网络2及毫米波馈电网络3，其中，双频子阵列天线1为五层结构，如图2所示，具体为三层金属与两层介质间隔放置，从外到内依次为微波辐射阵列11、第一介质层12、毫米波辐射阵列13、第二介质层14和金属板15，其中，微波辐射阵列11及毫米波辐射阵列13分别设置在双频子阵列天线1的金属层上，在具体制作时，采用印刷电路板的制作方式制作，且在双频子阵列天线1在固定在正八边形柱体的侧面时，微波辐射阵列11向外，金属板15向内。
如图3所示，图3示出了微波辐射阵列11的结构示意图。该微波辐射阵列11包括多个微波线性阵列111，每个微波线性阵列111中的微带馈线112上设置有微波移相器113，且每个微带馈线112的同侧等间距设置有多个微波辐射单元114，且多个微波线性阵列111呈阵列方式排列。具体的，微波辐射阵列11设置在双频子阵列天线1的顶层金属层(最外层金属层)上，微波辐射阵列11为多个垂直方向的串馈线阵(微波线性阵列111)组成，每个线阵的同侧排布有微波辐射单元114，每个线阵的微带馈电口设置于阵列顶部，以图2所示的方向为参考方向，即微带馈线112的馈电口位于正多边形柱体侧面上靠近顶面的一端，在每个线阵的微带馈线112上设置有微波移相器113。
其中，微波线性阵列111的个数为4个、8个或16个，具体数目由微波扫描波束在方位面的波束宽度和微波波束增益确定。继续参考图3，图3示出了微波线性阵列111采用4个的结构，4个微波线性阵列111沿水平方向(以图3所示的方向为参考方向)上排列，在其采用8个或16个时，在采用4个微波线性阵列111的结构上在水平方向继续排列。
如图5所示，图5示出了微波馈电网络2的结构示意图，其中，微波馈 电网络2位于正多边形柱体的顶面，且微波馈电网络2包括多个微波开关21以及与每个微波开关21对应的微带功分网络22，且微带功分网络22与微波辐射阵列11一一对应连接。其中，控制微波开关网络的微波开关21可以将微波开关网络与其中一路微带功分网络22连通，而与其余路微带功分网络22断开，实现微波信号在微带功分网络22之间切换，每个微带功分网络22均与对应侧面的微波辐射阵列11的微带馈电口连接。在本实施例中采用8个微波线性阵列111时，微波馈电网络2包括8个微波开关21和8个微带功分网络22，微波馈电网络2设置于正八边形柱体的顶面，每个微带功分网络22分别与位于正八边形柱体每个侧面的微波辐射阵列11相连。
如图4所示，图4示出了本发明实施例提供的毫米波辐射阵列13，该毫米波辐射阵列13包括：多个阵列排列的毫米波线性阵列131，且每个毫米波线性阵列131连接有毫米波波导微带转换132，毫米波波导微带转换132的输出微带线133上设置有毫米波移相器134，输出微带线133的同一侧还设置有多个四贴片毫米波辐射单元135；在输出微带线133的另一侧具有其他输出微带线133时，该输出微带线133的另一侧设置有多个两贴片毫米波辐射单元136，且每个两贴片毫米波辐射单元136位于与其相邻的一个输出微带线133上的两个相邻的四贴片毫米波辐射单元135之间。具体的，毫米波辐射阵列13设置在双频子阵列天线1的中间金属层，该毫米波辐射阵列13为多个垂直方向的毫米波串馈线阵(即毫米波线性阵列131)组成，每个毫米波串馈线阵的馈电微带线左右交错排布有毫米波辐射单元，相邻两个毫米波串馈线阵的毫米波辐射单元交指排列，每个毫米波串馈线阵由波导微带转换馈电口馈电，且设置于阵列底部，即如图4所示，以图4所示的毫米波辐射阵列13的放置方向为参考方向，毫米波波导微带转换132设置在正多边形柱体侧面上靠近底面的一端。此外，在每个线阵的微带馈线112上还设置有毫米波移相器134。
其中，毫米波辐射阵列13所包含的毫米波线性阵列131的数目可以是4、8、16等，具体数目由毫米波扫描波束在方位面的波束宽度和毫米波波束增益确定。如图4所示，图4示出了毫米波线性阵列131采用4个的结构，4个毫 米波线性阵列131沿水平方向(以图4所示的方向为参考方向)上排列，在其采用8个或16个时，在采用4个毫米波线性阵列131的结构上在水平方向继续排列。
如图6所示，图6示出了毫米波馈电网络3的结构示意图。该毫米波馈电网络3包括毫米波旋转关节31以及与每个毫米波旋转关节31连接的毫米波功分网络32，且毫米波功分网络31与毫米波辐射阵列13一一对应连接。具体的，毫米波馈电网络3设置在正多边形柱体底部，即毫米波馈电网络3位于正多边形柱体的底面。在具体使用时，转动毫米波旋转关节31可以将毫米波旋转关节31与其中一路毫米波功分网络32连通，而与其余路毫米波功分网络32断开，实现毫米波信号在毫米波功分网络32之间切换，每个毫米波功分网络32与对应侧面的毫米波辐射阵列13的波导微带转换馈电口连接。
通过上述描述可以看出，本实施例提供的微波毫米波双频天线中，微波毫米波双频段上下分层馈电，微波馈电网络2为微波开关21切换网络，位于多面柱体天线顶部，毫米波馈电网络3为毫米波旋转关节31切换网络，位于多面柱体天线底部，采用上述结构时，微波毫米波馈电网络3上下分离便于结构布局，微波开关21切换网络结构简单、技术成熟，毫米波旋转关节31切换网络损耗小；
此外，微波毫米波双频子阵列中的微波毫米波辐射阵列的分层串馈线阵布局，微波辐射阵列11位于顶层，垂直方向为串馈线阵，微波辐射单元114在馈电微带线同侧排布，从顶部由微带馈电网络馈电，毫米波辐射阵列13位于中间层，垂直方向为串馈线阵，毫米波辐射单元在馈电微带线左右交错排布，从底部由毫米波馈电网络3馈电，在采用上述结构时，微波毫米波辐射阵列13分层布局便于微波毫米波频段馈电网络设计，垂直方向串馈线阵可以利用较少的移相器实现水平方向的电扫描，毫米波辐射单元在馈线左右交错排布可以降低俯仰面副瓣电平。
