在实际应用中，短路枝节201与馈电传输线202的材质可选为铜，短路枝节201与馈电传输线202可以通过电路印刷工艺印刷在电路板20的表面上，在一个示例中，短路枝节201与馈电传输线202可以印刷在电路板20背向金属型材10的一面。
本申请实施例中，短路枝节201设置有第一横向枝节2011，电路板20与金属型材10连接，示例性地，电子设备包括显示屏和设置在显示屏周围的金属边框，金属型材10可以是电子设备的金属边框，电子设备的金属边框包括朝外的外观面和朝向电子设备内部的背面，电路板20可拆卸式地连接在金属边框的背面，例如，电路板20可以通过螺丝、卡扣等方式固定在金属边框的背面上，使得电路板20上的短路枝节201的第一横向枝节2011与金属边框上的缝隙101正对设置，馈电传输线202在缝隙101的宽度方向上横跨缝隙101，示例性地，正对设置为：当缝隙101垂直于电路板20投影到电路板20上时，在电路板20上具有一矩形投影区域，短路枝节201的第一横向枝节2011位于该矩形投影区域内。
本申请实施例的缝隙天线包括金属型材和电路板，金属型材设置有缝隙，电路板的一面设置有与电路板电连接的短路枝节和馈电传输线，电路板与金属型材连接，以使得短路枝节的横向枝节与缝隙正对设置，馈电传输线在缝隙的宽度方向上横跨缝隙。本申请实施例的缝隙天线可以将电子设备的金属边框作为金属型材，通过在金属型材上设置天线缝隙作为辐射源，电路板可以直接层叠于电子设备的边框上，无需为天线设置净空区域，有利于电子设备在厚度外观方面的设计。
如图4所示，在本申请的可选实施例中，在缝隙101的长度方向上，缝隙101的中心线与短路枝节201的第一横向枝节2011的中心线重合，即第一横向枝节2011在长度方向上的中心线到缝隙101的两条边的距离相等，从而使得第缝隙101上激励的电磁场最强，能够提高缝隙天线向空间辐射电磁波的能力。
如图4所示，在本申请的可选实施例中，短路枝节201还包括与短路枝节201的第一横向枝节2011垂直连接的竖向枝节2012，短路枝节201的竖向枝节2012接地，具体地，竖向枝节2012未与第一横向枝节2011连接的一端通过接地点与电路板20的接地面连接。如图4所示，在一个示例中，短路枝节201的竖向枝节2012与短路枝节201的第一横向枝节2011的中点连接以构成T型短路枝节，在另一个示例中，短路枝节201的竖向枝节2012与短路枝节201的第一横向枝节2011的一个端点连接以构成L型短路枝节，当然，在实际应用中，本领域技术人员还可以根据实际需要将短路枝节201的竖向枝节2012与短路枝节201的第一横向枝节2011设置为“十”字型短路枝节等其他形状，本申请实 施例对短路枝节201的形状不加以限制，以能够保证短路枝节201的第一横向枝节2011与缝隙101正对设置即可。
如图5所示，在本申请的可选实施例中，馈电传输线202还设置有与馈电传输线202垂直连接的第二横向枝节2021，馈电传输线202的第二横向枝节2021与缝隙101正对设置，即当缝隙101垂直于电路板20投影到电路板20上时，在电路板20上具有一矩形投影区域，馈电传输线202的第二横向枝节2021位于该矩形投影区域内。可选地，在缝隙101的长度方向上，缝隙101的中心线与馈电传输线202的第二横向枝节2021的中心线重合。通过在馈电传输线202上增添第二横向枝节2021，可以引入新的高频谐振，提高了缝隙天线在5G频段的带宽。
如图14所示为图5中馈电传输线202增加第二横向枝节2021后的反射损耗率的示意图，如图15所示为图4中馈电传输线202未添加第二横向枝节2021的反射损耗率的示意图，如图14和图15所示，两种缝隙天线在谐振频率f1和谐振频率f2处的反射损耗均比较低，但图14中添加了第二横向枝节2021后，缝隙天线在低频f1的5dB辐射频段为2.3～2.5GHz，高频f2的3dB辐射频段为5.15～6.05GHz，图15中未添加第二横向枝节2021时，缝隙天线在低频f1的5dB辐射频段为2.3～2.5GHz；高频f2的3dB辐射频段为5.15～5.7GHz，由此可见，增加第二横向枝节2021和未增加第二横向枝节2021在低频的辐射频段均为2.3～2.5GHz，而增加了第二横向枝节2021后，高频f2的5G带宽增加约320M。
如图5所示，在本申请的可选实施例中，电路板20的尺寸为63×15.8mm(长×宽)，厚度为1.7mm，则可以设置缝隙101的尺寸为50.2×2.8mm(长×宽)，馈电传输线202距离缝隙101右边末端6.5mm，馈电传输线202的宽度为1mm；短路枝节201的中心距离缝隙101左端24.8mm，距离缝隙101右端25.4mm，在缝隙101的长度方向上，缝隙101的中心线与短路枝节201的第一横向枝节2011的中心线重合，短路枝节201的第一横向枝节2011长为13.4mm，宽度为0.5mm。
当然，在实际应用中，本领域技术人员可以根据实际情况设置电路板、缝隙、短路枝节、馈电传输线的结构尺寸以及与缝隙的相对位置，本申请实施例对此不加以限制。
如图6-图9所示，在本申请的可选实施例中，缝隙天线100还包括一个固定件40，固定件40可以是用于将电路板20固定在金属型材10上，并且使得电路板20上的短路枝节201和馈电传输线202相对于缝隙101的位置相对固定的部件。固定件40可以是非金属件，例如可以是塑胶件或者绝缘陶瓷等非导电部件，该固定件40与金属型材10相对的一面设置有与缝隙101适配的凸台401， 背向凸台401的一面设置有固定部402，当固定件40与金属型材10连接时，凸台401嵌入缝隙101中，可选地，凸台401的外轮廓可以与缝隙101的轮廓相同以起到定位作业，例如，缝隙101为细长形的方孔，凸台401可以是细长形的方形凸台，使得凸台401可以嵌入缝隙101中，其中，凸台401与缝隙101的配合间隙本领域技术人员可以根据实际情况设置，使得凸台401与缝隙101适配且起到定位作用即可，电路板20设置于固定部402中后，短路枝节201的第一横向枝节2011与缝隙101正对设置，可选地，在缝隙101的长度方向上，使得缝隙101的中心线与短路枝节201的第一横向枝节2011的中心线重合。
在本申请的一个示例中，装配时，将固定件40的凸台401嵌入金属型材10的缝隙101中，然后用胶水、螺丝等方式将固定件40与金属型材10固定，然后将电路板20放置在固定件40的固定部402上通过螺丝锁紧电路板20，通过该固定部402可以使电路板20上的短路枝节201的第一横向枝节2011位于缝隙101在电路板20的投影区域内与缝隙101正对设置，馈电传输线202在缝隙101的宽度方向上横跨缝隙101。当然，也可以先将电路板20先放置于固定部402，然后将固定件40放置于金属型材10上，通过螺丝同时将电路板20固定在固定件40上，以及将固定件40固定在金属型材10上。
如图8和图9所示，在本申请的一个示例中，固定件40可以包括一个方形底板以及设置于方形底板三条边上的围栏405，围栏405上设置有压紧电路板20的卡扣404，底板和围栏405构成一放置电路板20固定部402，背向固定部402的一面设置有凸台401，凸台401的位置可以设置为：当电路板20放置于固定部402，且电路板20的三条边与围栏405接触时，固定件40的凸台401嵌入缝隙101中后，电路板20上的短路枝节201的第一横向枝节2011位于缝隙101在电路板20的投影区域内与缝隙101正对设置，馈电传输线202在缝隙101的宽度方向上横跨缝隙101，可选地，在缝隙101长度方向上，短路枝节201的第一横向枝节2011的中心线与缝隙101的中心线重合。
本申请实施例的缝隙天线，金属型材设置有缝隙，固定件设置有固定电路板的固定部以及与缝隙适配的凸台，电路板固定在固定部后，当固定件与金属型材连接时，凸台嵌入到缝隙中起到定位作用，使得电路板上的短路枝节的横向枝节与缝隙正对设置，馈电传输线在缝隙的宽度方向上横跨缝隙，即在电路板固定后能够保证短路枝节的横向枝节相对于缝隙的相对位置，从而保证了缝隙天线具有准确的辐射频率和良好的辐射性能。
如图10-图13所示，在本申请的可选实施例中，缝隙天线100还包括金属背腔30，金属背腔30可以为不锈钢等导电金属形成的腔体，金属背腔30盖设于金属型材10与电路板20连接的一面且与地端连接，电路板20位于金属背腔 30的腔体301中，馈电传输线202的一端与金属背腔30电连接。可选地，金属背腔30与电路板20可拆卸式连接，或者金属背腔30与金属型材10可拆卸式连接，其中，可拆卸式连接可以为螺钉、卡扣、胶水粘合等连接方式中的一种，以方便对缝隙天线100进行检修、维护等。
在本申请的一个实施例中，馈电传输线202通过导电件与金属背腔30的侧壁电连接，例如，馈电传输线202的一端可以通过金属弹片或导电布与金属背腔30的侧壁电连接。示例性地，围栏405上还设置有一缺口403，以使得馈电传输线202可以与金属背腔30电连接，例如，馈电传输线202通过缺口403延伸到金属背腔30的侧壁上，或者金属背腔30上的弹片、导电布等通过缺口403连接到馈电传输线202等。
图11和图12为图10中剖面A和剖面B的示意图，如图11和图12所示，金属型材10设置有缝隙101，固定件40的凸台401嵌入到缝隙101中，电路板20固定在固定件40上，短路枝节201和馈电传输线202在电路板20的表面，金属背腔30覆盖固定件40和电路板20。在图11中，短路枝节201的第一横向枝节2011的中心线与缝隙101的中心线重合，在图12中，馈电传输线202的一端与金属背腔30接触以实现电连接。
在实际应用中，金属背腔30盖设于金属型材10与电路板20连接的一面且与地端连接，例如与电子设备的主板的地端连接，或者与金属型材10连接后通过金属型材10连接至地端等。金属背腔30盖设于金属型材10后，使得电路板20、固定件40被金属背腔30所覆盖，容纳在金属背腔30的腔体301中，金属背腔30可以屏蔽电子设备内部其他电路模块对短路枝节201与馈电传输线202造成电磁干扰。
图16和图17分别为频率为2.4GHz和5.4GHz时的辐射方向的示意图，从图16和图17可知，增加了金属背腔30后，缝隙天线辐射呈单向性，缝隙天线在Z方向上的辐射强度相对于其他方向的强度大。
本申请实施例中，在电路板20上印刷短路枝节201，通过不同尺寸的短路枝节201，以及通过短路枝节201相对缝隙101的位置对缝隙天线100的工作模式进行扰动，从而可以根据不同工作频段设计不同的缝隙101和短路枝节201，提高了设计的自由度。同时，通过跨接在缝隙101宽度方向上的馈电传输线202进行馈电，并且馈电传输线202的一端通过金属背腔30短接至地端，通过设置馈电传输线202相对于缝隙101的不同位置以调整缝隙天线100的输入阻抗，以达到阻抗匹配，从而实现对缝隙天线100反射损耗的优化。
可选地，馈电传输线202增加横向枝节，引入新的高频谐振，提高了缝隙天线在5G频段的带宽。
可选地，在缝隙101和电路板20的后方安装金属背腔30，使得缝隙天线100辐射呈现单向性，降低了缝隙天线100的反射损耗，避免了电子设备内部电路对缝隙天线100的影响，从而提高了缝隙天线的辐射效率。
可选地，通过设置固定件40来将电路板20固定到金属型材10上，电路板20上的短路枝节201和馈电传输线202相对于缝隙101的位置得到保障，实现短路枝节201和馈电传输线202相对于缝隙101准确配合，提高了缝隙天线的辐射性能。
如图18所示，本申请实施例提供了一种电子设备50，电子设备50包括显示屏、位于显示屏周围的金属边框、以及本申请任一实施例的缝隙天线100，缝隙天线100中的金属型材为电子设备50的下边框501。
当然，缝隙天线100可以设置在电子设备50的任意一个金属边框上而不限于下边框501，即可以将缝隙天线100可以设置在电子设备50上边框、下边框、左边框、右边框中的至少一个边框上。
可选地，电子设备50包括一个或者一个以上的缝隙天线100，如图18所示的电子设备可以为显示设备，例如可以是电子交互白板，该电子交互白板包括显示屏502和位于显示屏502底部的下边框501，下边框501可以是固定显示屏502的金属框体，当缝隙天线100的数量为一个时，缝隙天线100可以设置在下边框501的中间位置，如图19所示，当缝隙天线的数量为2个时，2个缝隙天线100设置在下边框501且间隔设置，可选地，2个缝隙天线100可以对称地设置在下边框501上，当然还可以包括其他数量的缝隙天线，本申请实施例对此不加以限制。
由于本申请实施例的缝隙天线100具有良好的辐射方向，相对于装配在电子设备边框底部的天线使得天线辐射方向朝向地面方向的情况，本申请实施例的电子设备中缝隙天线100可以设置在朝向信号源的方向，从而可以提高天线的下行吞吐量，以下为本申请实施例的缝隙天线100与传统天线的吞吐量的测试数据对比：
Figure PCTCN2020139273-appb-000001
Figure PCTCN2020139273-appb-000002
从上表可知，装配了本申请实施例的缝隙天线100的电子设备的天线的下行吞吐量高于传统天线的下行吞吐量。
本申请实施例的电子设备中，缝隙天线可以将电子设备的金属边框作为金属型材，通过在金属边框上设置缝隙作为辐射源，电路板可以直接层叠于电子设备的金属边框上，无需为天线设置净空区域，有利于电子设备在厚度外观方面的设计。
可选地，通过固定件将电路板固定在电子设备的金属边框上，使得电路板上的短路枝节的横向枝节位于缝隙在电路板的投影区域内，馈电传输线在缝隙的宽度方向上横跨缝隙，即在电路板固定后能够保证短路枝节的横向枝节相对于缝隙的相对位置，从而保证了缝隙天线具有准确的辐射频率和良好的辐射性能。
可选地，相对于装配在电子设备边框底部的天线，本申请实施例中缝隙天线的装配方式使得辐射方向更加契合使用场景，可以大大提高缝隙天线的下行吞吐量。
在本说明书的描述中，参考术语“一实施例”、“示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚器件，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以适当组合，形成本领域技术人员可以理解的其他实施方式。
