优选地，在依据本公开内容的一个实施例之中，所述辐射元件上设置有四个固定部，并且其中，所述支撑构件的四个端部处分别构造有与所述 固定部相匹配的固定卡合部。
可选地或者替代地，在依据本公开内容的一个实施例之中，在第二组装状态下，所述支撑构件的端平面处于所述辐射元件所在的平面之中或者超出所述辐射元件所在的平面。优选地，在依据本公开内容的一个实施例之中，所述支撑构件在其远离所述辐射元件的一侧被焊接至功分板。
此外，本公开内容的第二方面提出了一种天线，所述天线包括：根据本公开内容的第一方面所述的辐射振子；以及反射板，其中，所述辐射振子安装在所述反射板上。
综上所述，由于辐射元件和支撑构件之间的固定能够借助于其分别包括的固定部和固定卡合部之间的配合得以实现，而不需要焊接，所以其组装方式与传统的辐射振子有较大区别，进而使得依据本公开内容所公开的辐射振子能够有利于提升产品组装效率。此外，由于依据本公开内容所提出的辐射振子采用的组合一体化的结构形式，从而能够有效地增强辐射振子的强度。再者，由于该固定方式是可拆卸的，所以依据本公开内容所公开的辐射振子的维修成本也能够大为降低。

具体实施方式
在以下优选的实施例的具体描述中，将参考构成本公开内容一部分的所附的附图。所附的附图通过示例的方式示出了能够实现本公开内容的特定的实施例。示例的实施例并不旨在穷尽根据本公开内容的所有实施例。可以理解，在不偏离本公开内容的范围的前提下，可以利用其他实施例，也可以进行结构性或者逻辑性的修改。因此，以下的具体描述仅仅是示例性的而非限制性的，并且本公开内容的范围由所附的权利要求所限定。
现有技术中存在的如下技术问题，即现有的固定方式操作起来不方便而且效率低，而且在需要更换掉其中出现故障的诸如辐射元件的某个零件时的不够经济的维修成本。
针对上述技术问题，本公开内容的发明人想到设计一种改变固定方式的辐射振子，其能够显著地提高辐射振子的组装效率并降低维护成本。
以下将结合附图对本公开内容所提出的辐射振子进行详细说明。
为了改变传统的辐射振子的辐射元件和支撑构件之间通常通过焊接连接的方式进行固定所带来的技术问题，本公开内容采用借助于固定部和固定卡合部之间的配合来实现辐射元件和支撑构件之间的固定，从而能够不使用焊接的固定方式，进而能够显著地提高辐射振子的组装效率并降低维护成本。
具体而言，图1A示出了依据本公开内容的一个实施例的辐射元件110的示意图，图1B示出了依据本公开内容的一个实施例的支撑构件120的示意图，而且图1C示出了依据本公开内容的一个实施例的辐射振子100的立体图。从图1A之中可以看出，在辐射振子100的辐射元件110上设置有四个固定部111，每个固定部111分别包括悬臂1111、接合部1112和限位部1113。具体而言，如图1A所示，这四个固定部111的结构类似，故仅以右 下角的固定部111作为示例来描述依据本公开内容所提出的辐射元件110的结构。此外，应当理解，在此示出的四个固定部111仅仅是示例性的而非限制性的，其他数量的固定部111也是可能的，例如仅具有两个用于固定目的的固定部111，当然，其他数量的即多个固定部111的设置情况也是可行的，只要能够通过可拆卸的方式将辐射元件110和支撑构件120进行固定或者拆卸即可。
在此，本领域的技术人员应当了解，本公开内容的主要发明构思在于：由于辐射元件和支撑构件之间的固定能够借助于其分别包括的固定部和固定卡合部之间的配合得以实现，而不需要焊接，所以其组装方式与传统的辐射振子有较大区别，进而使得依据本公开内容所公开的辐射振子能够有利于提升产品组装效率。因此，只要固定部和固定卡合部之间的制造公差配合得当，其固定方式既能够非常灵活，也可以固定的相对可靠。换句话说，此处的悬臂1111和限位部1113是为了进一步优化固定效果而设置的，并非是必须具备的，其属于进一步的改进。
可选地或者附加地，所述辐射元件110的中间部分被构造为设置有十字槽。以这样的方式能够有利于辐射振子100的阻抗匹配和频段调整。此外，所述辐射元件110的中心位置被构造为设置有用于组装定位的圆形孔112。基于该定位的圆形孔112的位置，例如能够辅助于用于安装目的的工件，借助于该工件和圆形孔112之间的配合，以便实现辐射元件110和支撑构件120的快速定位，进而提高依据本公开内容所公开的辐射振子100的组装效率。在此，每个固定部111例如均呈圆弧状，而且例如具有围绕圆形孔112旋转对称的结构，优选地，四个固定部111的对应部分分别相差90度的旋转角度。
图1B示出了依据本公开内容所公开的辐射振子100所使用的支撑构件120。具体而言，从图1B之中可以看出，依据本公开内容所公开的支撑构件120包括两块相互正交的支撑子构件121和支撑子构件122。在此，支撑子构件121在其中间部分具有一个朝向下的槽1213(图1B所示方向向下)，并且支撑子构件122在其中间部分也具有一个另一朝向上的槽1223(图1B所示方向向上)。在组装时，将支撑子构件121上的槽朝着支撑子构件122 上的槽插过去，即能够将两个支撑子构件121和122进行对插，形成一个十字形状的支撑构件120。从图1B之中还可以看出，每个支撑子构件121或者支撑子构件122上都可以蚀刻有近似倒U形的金属薄膜1212，所述近似倒U形的金属薄膜1212被构造用于以耦合的方式为所述辐射元件110(在图1A中予以示出)馈电。以这样的方式在对插的两块板材121和122上面蚀刻有近似倒U形的金属铜箔，从而有利于为诸如水平方形片的辐射元件110做耦合馈电。
此外，从图1B之中还可以看出，每个支撑子构件121或者支撑子构件122可以在其端部分别具有一个与上述固定部111相匹配的固定卡合部1211，而且该固定卡合部1211例如能够包括上下设置的两个子部分，即固定卡合部1211的固定卡合子部分1211a和固定卡合子部分1211b。在此，应当理解，此处示出的示例中每个支撑子构件121或者支撑子构件122的两侧上端部均设置有一个与上述固定部111相匹配的固定卡合部1211仅仅是示例性的而非限制性的，也能够例如仅仅在其中一个支撑子构件121或者支撑子构件122的端部设置两个与上述固定部111相匹配的固定卡合部1211，或者在每个支撑子构件121或者支撑子构件122上分别仅设置一个与上述固定部111相匹配的固定卡合部1211，只要能够将辐射元件110借助于十字状的支撑构件120稳定地固定至与支撑构件120例如通过焊接等方式固定在一起的结构(例如印刷电路板PCB)即可。，换句话说，支撑构件120例如可以先通过焊接等方式稳定地固定在印刷电路板PCB板上，然后辐射元件110再在支撑构件120的另一端上安装，进而确保辐射单元110的稳定安装得以实现。
在具体组装过程中，可以先将两个支撑子构件121和122进行对插，形成一个十字形状的支撑构件120，然后将辐射元件110放置在十字形状的支撑构件120上方，以便将固定部111与固定卡合部1211对准，此时，固定卡合子部分1211a将会把悬臂1111向上顶起发生形变。此时，如果从图1A所示的图示从上往下俯视，此时，固定卡合部1211在悬臂1111下方，但是接合部1112并不位于固定卡合子部分1211a和固定卡合子部分1211b之间，而且固定卡合部1211也并非抵接在悬臂1111和所述限位部1113之 间。
此时，在俯视的情况下，如果将辐射元件110相对于支撑构件120进行逆时针方向的旋转，则能够将所述辐射振子100从所述第一组装状态切换至如图1C所示的第二组装状态。在所述第二组装状态下，即在如图1C所示的组装状态下，所述接合部1112位于所述固定卡合部1211的两个固定卡合子部分1211a和固定卡合子部分1211b之间、所述悬臂1111恢复自然状态并且所述固定卡合部1211抵接在所述悬臂1111和所述限位部1113之间。在图1A、图1B和图1C所示出的示例之中，所述悬臂1111被构造为弹舌片，在所述第二组装状态下，所述弹舌片和所述限位部1113位于所述固定卡合部1211的两侧。此时，由于固定卡合部1211抵接在所述悬臂1111和所述限位部1113之间，所以辐射元件110不会相对于支撑构件120在顺时针或者逆时针的方向上转动；而在另一个方向上即上下方向上，由于接合部1112位于所述固定卡合部1211的两个固定卡合子部分1211a和固定卡合子部分1211b之间，所以辐射元件110不会相对于支撑构件120上下移动。同时在顺时针或者逆时针的方向上而且在上下方向上将辐射元件110相对于支撑构件120进行了固定，所以便能够将辐射元件110相对于支撑构件120进行稳定的固定了。
在此，优选地，所述固定卡合部1211的两个子部分1211a和1211b之间的间距与所述接合部1112的厚度或者所述辐射元件110的厚度相关联，如果间距和后两者的厚度恰好一样，则能够实现更为稳定的固定。进一步优选地，所述悬臂1111和所述限位部1113之间的间距与所述支撑构件120的支撑子构件121或者支撑子构件122的厚度相关联，如果该间距和后者的厚度恰好一样，则能够实现更为稳定的固定。
在需要更换某个部件的情况下，能够例如借助于工具将悬臂1111向上吸起或者顶起，与此同时将辐射元件110相对于支撑构件120顺时针旋转，此时便能够将辐射元件110与支撑构件120分离了。概括地讲，通过将所述辐射元件111相对于所述支撑构件120转动，以将所述第一组装状态切换至所述第二组装状态或者相反地将所述第二组装状态切换至所述第一组装状态。为了实现以转动方式进行所述第一组装状态和所述第二组装状态 之间的切换，所述至少两个固定部111被构造在一个圆周结构上，以使得能够通过将所述支撑构件120相对于所述辐射元件110进行旋转运动在所述第一组装状态和所述第二组装状态之间切换。本领域的技术人员应当了解，在其他非转动方式进行的所述第一组装状态和所述第二组装状态之间的切换的情况下，固定部也可以不在同一圆周结构上，此时也能够实现所述第一组装状态和所述第二组组装状态之间的切换。
此外，从图1C之中可以看出，所述辐射振子100还包括一个功分板130，所述支撑构120在其远离所述辐射元件110的一侧被焊接至功分板130，以便能够经由支撑构件120上的近似倒U形的金属薄膜1212将功分板130上的信号耦合馈电至辐射元件110。
以下将结合图2至图5来描述依据本公开内容所公开的辐射振子的其他实现形式。
图2示出了依据本公开内容的另一个实施例的辐射振子200的分解视图。在图2所示的辐射振子200之中可以看出，辐射振子200包括辐射元件210、支撑构件220和功分板230。从图2之中可以看出，在辐射振子200的辐射元件210上设置有四个固定部211，每个固定部211分别包括悬臂2111、接合部2112和限位部2113。具体而言，如图2所示，这四个固定部211的结构类似，故仅以右下角的固定部211作为示例来描述依据本公开内容所提出的辐射元件210的结构。此外，应当理解，在此示出的四个固定部211仅仅是示例性的而非限制性的，其他数量的固定部211也是可能的，例如仅具有两个用于固定目的的固定部211，当然，其他数量的即多个四个固定部211的设置情况也是可行的，只要能够通过可拆卸的方式将辐射元件210和支撑构件220进行固定或者拆卸即可。
从图2之中可以看出，与图1C所示出的辐射振子100的不同之处在于：图2所示出的辐射振子200的固定部211的形状与辐射振子100的固定部111的形状不同。图2中的悬臂2111、接合部2112和限位部2113所处于的平面低于辐射元件210所在的平面，即辐射元件210上具有凹陷的结构。可选地，悬臂2111可以是处于低于辐射元件210的平面之中，也可以稍微有些上翘的结构。依据本公开内容的图2所示出的辐射振子200的组装方 式以及固定原理和图1C所示出的结构类似，故在此不再赘述。
图3示出了依据本公开内容的又一个实施例的辐射振子300的组装视图。在图3所示的辐射振子300之中可以看出，辐射振子300包括辐射元件310和支撑构件320。从图3之中可以看出，在辐射振子300的辐射元件310上设置有四个固定部311，每个固定部311分别包括悬臂3111、接合部3112和限位部3113。具体而言，如图3所示，这四个固定部311的结构类似，故仅以右下角的固定部311作为示例来描述依据本公开内容所提出的辐射元件310的结构。此外，应当理解，在此示出的四个固定部311仅仅是示例性的而非限制性的，其他数量的固定部311也是可能的，例如仅具有两个用于固定目的的固定部311，当然，其他数量的即多个四个固定部311的设置情况也是可行的，只要能够通过可拆卸的方式将辐射元件310和支撑构件320进行固定或者拆卸即可。
从图3之中可以看出，与图1C所示出的辐射振子100的不同之处在于：图3所示出的辐射振子300的固定部311的形状与辐射振子100的固定部111的形状不同。图3中的接合部3112和限位部3113所处于的平面低于辐射元件310所在的平面，即辐射元件310上具有凹陷的结构。可选地，悬臂3111的固定端可以是处于辐射元件310的平面之中，而悬臂3111的自由端可以是处于低于辐射元件310的平面之中。换句话说，悬臂3111可以使下弯式弹舌片结构。依据本公开内容的图3所示出的辐射振子300的组装方式以及固定原理和图1C所示出的结构类似，故在此不再赘述。
图4示出了依据本公开内容的再一个实施例的辐射振子400的分解视图。在图4所示的辐射振子400之中可以看出，辐射振子400包括辐射元件410、支撑构件420和功分板430。从图4之中可以看出，在辐射振子400的辐射元件410上设置有四个固定部411，每个固定部411分别包括悬臂、接合部和限位部。具体而言，如图4所示，这四个固定部411的结构类似，故仅以右下角的固定部411作为示例来描述依据本公开内容所提出的辐射元件410的结构。此外，应当理解，在此示出的四个固定部411仅仅是示例性的而非限制性的，其他数量的固定部411也是可能的，例如仅具有两个用于固定目的的固定部411，当然，其他数量的即多个四个固定部411 的设置情况也是可行的，只要能够通过可拆卸的方式将辐射元件410和支撑构件420进行固定或者拆卸即可。
从图4之中可以看出，与图1C所示出的辐射振子100的不同之处在于：图4所示出的辐射振子400的辐射元件410上还冲切有四组双圆环槽415，这四组双圆环槽415的设置能够便于调节辐射振子400的射频性能、瓣宽、增益以及辐射方向图。依据本公开内容的图4所示出的辐射振子400的组装方式以及固定原理和图1C所示出的结构类似，故在此不再赘述。
图5示出了依据本公开内容的又一个实施例的辐射振子500的分解视图。在图5所示的辐射振子500之中可以看出，辐射振子500包括辐射元件510、支撑构件520和功分板530。从图5之中可以看出，在辐射振子500的辐射元件510上设置有四个固定部511，每个固定部511分别包括悬臂、接合部和限位部。具体而言，如图5所示，这四个固定部511的结构类似，故仅以右下角的固定部511作为示例来描述依据本公开内容所提出的辐射元件510的结构。此外，应当理解，在此示出的四个固定部511仅仅是示例性的而非限制性的，其他数量的固定部511也是可能的，例如仅具有两个用于固定目的的固定部511，当然，其他数量的即多个四个固定部511的设置情况也是可行的，只要能够通过可拆卸的方式将辐射元件510和支撑构件520进行固定或者拆卸即可。
从图5之中可以看出，与图4所示出的辐射振子400的不同之处在于：图5所示出的辐射振子500的固定部511的形状与辐射振子400的固定部411的形状不同。图5中的接合部和限位部所处于的平面高于辐射元件510所在的平面，即辐射元件510上具有凸包的结构。可选地，悬臂的自由端可以是处于辐射元件510的平面之中，而接合部和限位部所处于的平面高于辐射元件510所在的平面。与此同时，支撑构件520的固定卡合部也将相应地延伸超过辐射元件510所处的平面，从而实现与上述的凸包结构的配合，进而实现辐射元件510和支撑构件520之间的固定。依据本公开内容的图5所示出的辐射振子500的组装方式以及固定原理和图4所示出的结构类似，故在此不再赘述。
此外，本公开内容的第二方面提出了一种天线，所述天线包括根据本 公开内容的上述方面所述的辐射振子以及与反射板，其中，所述辐射振子安装在所述反射板上。
以上所设计的辐射振子的优点在于如下方面：
首先，采用的耦合馈电结构能够扩展包括该辐射振子的天线的工作带宽，并且因为馈电结构和引向结构能够耦合在一起，所以这样所形成的辐射振子易于无源互调的稳定。
此外，采用耦合的馈电方式，使得所形成的辐射振子以及进而形成的天线容易获得较高的隔离度。而且采用的印刷电路板结构易于灵活调整辐射振子以及所形成的天线的工作频段和工作阻抗等S参数和方向图电性能，省去了开模的时间。在依据本公开内容所公开的辐射振子之中采用了四点馈电的结构，从而易于获得较高的交叉极化和阻抗匹配等电特性。本公开内容所提出的支撑构件通过直插方式组合成型的结构，其包括了垂直部分的四点耦合馈电和支撑结构，而在水平部分有一块钣金件组成。
概括地讲，在依据本公开内容的辐射振子之中，由于辐射元件和支撑构件之间的固定能够借助于其分别包括的固定部和固定卡合部之间的配合得以实现，而不需要焊接，所以其组装方式与传统的辐射振子有较大区别，进而使得依据本公开内容所公开的辐射振子能够有利于提升产品组装效率。此外，由于依据本公开内容所提出的辐射振子采用的组合一体化的结构形式，从而能够有效地增强辐射振子的强度。再者，由于该固定方式是可拆卸的，所以依据本公开内容所公开的辐射振子的维修成本也能够大为降低。
尽管已经描述了本公开内容的不同示例性的实施例，但对于本领域技术人员而言显而易见的是，能够进行不同的改变和修改，其能够在并未背离本公开内容的精神和范畴的情况下实现本公开内容的优点中的一个或一些优点。对于那些在本领域技术中相当熟练的技术人员来说，执行相同功能的其他部件可以适当地被替换。应当了解，在此参考特定的附图解释的特征可以与其他附图的特征组合，即使是在那些没有明确提及此的情况中。此外，可以或者在所有使用恰当的处理器指令的软件实现方式中或者在利用硬件逻辑和软件逻辑组合来获得同样结果的混合实现方式中实现本公开 内容的方法。这样的对根据本公开内容的方案的修改旨在被所附权利要求所覆盖。
