具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
如图4～11所示，本申请实施例提供了一种天线组件，包括：第一磁偶极子天线11；第一电偶极子天线21，第一电偶极子天线21的辐射体与第一磁偶极子天线11的辐射体焊接于第一馈电点A1，第一磁偶极子天线11的辐射体和第一电偶极子天线21的辐射体为片状的辐射体，第一磁偶极子天线11的辐射体垂直于第一电偶极子天线21的辐射体；第一电偶极子天线21的辐射体上具有第二馈电点A2，在第一电偶极子天线21的辐射体上，第一馈电点A1和第二馈电点A2之间连通。
具体地，第一磁偶极子天线11在水平方向上形成环形电流，类似磁流环。第一磁偶极子天线11的辐射体和第一电偶极子天线21的辐射体通过焊接的方式结合为一体，一方面实现了两者之间的固定，另一方面使两者之间电连接，即实现了两个天线的共地设计，共地设计可以使两个天线具有较小的净空，同时配合使第一馈电点A1和第二馈电点A2之间连通，从而保证了两个天线具有较佳的平衡度，另外，第一磁 偶极子天线11的辐射体垂直于第一电偶极子天线21的辐射体，即利用了天线极化相互垂直的特性，提高了天线的性能。
本申请实施例中的天线组件，将磁偶极子天线和电偶极子天线垂直交叉设置，且通过焊接的方式使两个天线的辐射体在第一馈电点焊接，形成共地结构，同时配合使第一馈电点和第二馈电点之间连通，从而在提高隔离度的前提下改善了不平衡度，提高了天线性能。
在一种可能的实施方式中，如图4～7所示，第一馈电点A1包括第一端F和第二端G，第二馈电点A2包括第一端F和第二端G；第一电偶极子天线21的辐射体包括第一辐射片31，第一辐射片31包括：第一枝节41，第一枝节41具有第一馈电点A1的第一端F；第二枝节42，第二枝节42具有第一馈电点A1的第二端G；第三枝节43，第三枝节43具有第二馈电点A2的第一端F；第四枝节44，第四枝节44具有第二馈电点A2的第二端G；巴伦结构5，巴伦结构5连接于第二枝节42、第三枝节43和第四枝节44；短路枝节6，第一枝节41通过短路枝节6连接于巴伦结构5。

具体地，第三点B3和第五点B5可以重合，也可以间隔一端距离，第一直线延伸部81的延伸方向可以垂直于第一条状部71。第二介质层302上可以设置有第二插接槽320，第二插接槽320的延伸方向可以为垂直于第一直线延伸部81的延伸方向，第二插接槽320从第二介质层302的边缘向内延伸至第一直线延伸部81和第二直线延伸部82的中间部分，第一磁偶极子天线11和第一电偶极子天线21可以通过第一插接槽310和第二插接槽320相互插接，插接后第一电偶极子天线21中第一枝节41的第一馈电点A1的第一端F与第一磁偶极子天线11中第一直线延伸部81的中间部分相邻，以便于两者被焊接在一起，插接后第一电偶极子天线21中第二枝节42的第一馈电点A1的第二端G与第一磁偶极子天线11中第二直线延伸部82的中间部分相邻，以便于两者被焊接在一起。
以下通过模拟仿真的结果对上述天线组件结构的效果进行说明，如图12～17所示，图12为图4～11中第一磁偶极子天线在2.45GHz下的电流仿真示意图，图13为图4～11中第一电偶极子天线在5GHz下的电流仿真示意图，图14为图4～11中第一磁偶极子天线在5.6GHz下的电流仿真示意图，图15为图4～11中第一电偶极子天线在2.45GHz下的电流仿真示意图，图16为图4～11中第一电偶极子天线在5.5GHz下的电流仿真示意图，图17为图4～11中第一电偶极子天线在6GHz下的电流仿真示意图，在图12～17中，箭头表示电流方向，符号“×”表示电流的反向点，即电流在“×”处反向，根据各电流仿真示意图，可以看出，第一磁偶极子天线的大部分电流流向为水平方向，第一电偶极子天线的大部分电流流向为竖直方向，即保证了两个天线的垂直极化。如图18～21所示，图18为图4～11中第一磁偶极子在2.45GHz下的方向图，图19为图4～11中第一磁偶极子在5GHz下的方向图，图20为图4～11中第一电偶极子在2.45GHz下的方向图，图21为图4～11中第一电偶极子在5GHz下的方向图。如图22和图23所示，图22为图4～11中天线组件在2.4GHz下的组合方向图，图23为图4～11中天线组件的S参数曲线示意图，在图22中，实线和虚线分别为两个天线的方向图曲线，其中频点1和频点2为两条曲线具有最大距离的位置，两者的差值即为天线的不平衡度，达到3.6dB，另外从图22中同一个天线的方向图曲线中，可以看出天线水平面不圆度较好，不圆度是指天线的水平面方向中最大值和最小值之差；从图23中可以看出，两个天线可以覆盖2.4GHz和5GHz双频谐振，实现双频覆盖。
在一种可能的实施方式中，如图24～26所示，天线组件还包括：第二电偶极子天线22，第一电偶极子天线21的辐射体垂直于第二电偶极子天线22的辐射体。例如可以两个电偶极子天线交叉放置，在与磁偶极子天线交叉放置，三个天线中的任意两者之间相互垂直，实现三天线之间的高隔离度。其中，第一电偶极子天线21的具体结构可以与上述实施例类似，第一磁偶极子天线11的具体结构可以与上述实施例类似，在此不再赘述。例如，图25中的第一电偶极子天线21具有第一焊接点C1和第二焊接点C2，第一电偶极子天线21在第一焊接点C1和第二焊接点C2焊接于第一磁偶极子天线11，其中第一焊接点C1和第二焊接点C2中的一者为第一馈电点，通过焊接可以使第一电偶极子天线21和第一磁偶极子天线11形成共地结构；图26中第二电偶极子天线22具有第三焊接点C3和第四焊接点C4，第二电偶极子天线22在 第三焊接点C3和第四焊接点C4焊接于第一磁偶极子天线11，其中第三焊接点C3和第四焊接点C4中的一者为馈电点，通过焊接可以使第二电偶极子天线22和第一磁偶极子天线11形成共地结构。
在一种可能的实施方式中，如图27～31所示，第一磁偶极子天线11的辐射体包括相互平行的第三辐射片和第四辐射片，第三辐射片和所述第四辐射片之间设置有第二介质层，在垂直于第三辐射片所在平面的方向上，第三辐射片和第四辐射片的边缘的正投影形成第一圆形O1的至少部分边缘，第一磁偶极子天线11的具体结构可以参见图8～11所示的结构和相关描述；第二磁偶极子天线12的辐射体包括相互平行的第五辐射片35和第六辐射片36，第五辐射片35和第六辐射片36之间设置有第三介质层，第五辐射片35和第六辐射片36均包括弧线延伸部，在垂直于第五辐射片35的方向上，第五辐射片35和第六辐射片36的弧线延伸部的正投影形成第二圆形O2的至少部分边缘，第二圆形O2的直径小于第一圆形O1的直径。
在一种可能的实施方式中，如图27～31所示，第二磁偶极子天线12的辐射体上具有第三馈电点A3，第三馈电点A3位于第二圆形O2的中间部分；第一电偶极子天线21的辐射体包括第一辐射片31和平行于第一辐射片31的第二辐射片32，第一辐射片31和第二辐射片32之间设置有第一介质层301，第二辐射片32包括焊接部，焊接部从第一馈电点A1延伸至第三馈电点A3，第二磁偶极子天线12与焊接部焊接于第三馈电点A3。即第一电偶极子天线21与第一磁偶极子天线11焊接于第一馈电点A1，以形成两者的共地结构，第一电偶极子天线21与第二磁偶极子天线12焊接于第三馈电点A3，以形成两者的共地结构。对于第一电偶极子天线21的具体结构，可以与上述实施例中的结构相同，也可以略有差异。在如图27～31所示结构中，例如可以通过第一电偶极子天线21实现5G单频垂直极化，覆盖水平面，通过第一磁偶极子天线11实现2.4G单频水平极化，通过第二磁偶极子天线12实现5G单频水平极化，三者错位共体设计，实现高隔离度。
本申请实施例还提供一种电子设备，包括上述各实施例中的天线组件，天线组件的具体结构和原理不再赘述，该电子设备具体可以为无线路由器等。
本申请实施例中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示单独存在A、同时存在A和B、单独存在B的情况。其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项”及其类似表达，是指的这些项中的任意组合，包括单项或复数项的任意组合。例如，a，b和c中的至少一项可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。
