当然，第一子基板121和第二子基板122也可以呈其他的夹角，例如锐角或钝角，本申请实施例对第一子基板121和第二子基板122的具体连接方式不进行限定。
第一子基板121可以承载第一天线阵列130，第一天线阵列130可以设置于第一子基板121。例如，第一天线阵列130可以设置于第一子基板121的上表面。第一天线阵列130上可以设有馈电点150，该馈电点150可以与馈源110电连接，从而第一天线阵列130可以通过该馈电点150与馈源110电连接，以传输第一无线信号。

上述毫米波对应的波长范围为1mm～10mm。由于毫米波的波长较短，传输过程中容易受到阻碍，因此，第一天线阵列130和第二天线阵列140均可以包括阵列排布的多个毫米波天线单元。
可以理解的是，当第一天线阵列130包括阵列排布的多个毫米波天线单元时，该馈电点150可以包括多个，以便于与第一天线阵列130的多个毫米波天线单元一一对应，使得一个毫米波天线单元连接于一个馈电点150。
可以理解的是，当第二天线阵列140通过第一馈线网络160连接于馈电点150时，第二天线阵列140上的每一个毫米波天线单元可以通过第一馈线网络160上对应的馈线连接于一个馈电点150。当然，第二天线阵列140上的每一个毫米波天线单元也可以通过第一馈线网络160上对应的馈线连接于一个第一天线阵列130上的一个毫米波天线单元，以通过第一天线阵列130上的一个毫米波天线单元与一个馈电点150间接连接。
本申请实施例的天线装置100，通过将多个毫米波天线单元间隔排布，有效地增强了第一天线阵列130和第二天线阵列140的传输性能，通过在介质基板120上设置矩阵排列的多个毫米波天线单元，可以满足第一天线阵列130、第二天线阵列140的5G毫米波频段传输的需求。需要说明的是，上述用于传输无线信号中的“传输”包含接收无线信号、发射无线信号，以及同时接收和发射无线信号。
请结合图2并请参考图5，图5为图2所示的天线装置的一种辐射方向示意图。当第一天线阵列130与馈源110电连接并传输第一无线信号时，第一天 线阵列130可以具有第一辐射方向A1，该第一辐射方向A1可以由主介质基板120的第一子基板121向外延伸并形成第一辐射区域。同理，当第二天线阵列140与馈源110电连接并传输第二无线信号时，第二天线阵列140可以具有第二辐射方向A2，该第二辐射方向A2可以由介质基板120的第二子基板122向外延伸并形成第二辐射区域。
可以理解的是，第一辐射方向A1可以是第一天线阵列130的主辐射方向，第二辐射方向A2可以是第二天线阵列140的主辐射方向。
可以理解的是，由于第一子基板121的延伸方向与第二子基板122的延伸方向相交，进而，第一辐射区域的大部分区域与第二辐射区域的大部分区域不重叠，第一天线阵列130的第一辐射方向A1不同于第二天线阵列140的第二辐射方向A2。
本申请实施例的电子设备10及天线装置100，第一天线阵列130设置于介质基板120的第一子基板121，第二天线阵列140设置于介质基板120的第二子基板122，第一天线阵列130和第二天线阵列140电连接于馈源110，使得第一天线阵列130具有第一辐射方向A1，第二天线阵列140具有第二辐射方向A2，第二辐射方向A2不同于与第一辐射方向A1。基于此，本申请实施例的天线装置100，一方面，天线装置100具有两个不同的辐射方向，天线装置100覆盖的信号方向更广，天线装置100的辐射性能更优；另一方面，第一子基板121的延伸方向与第二子基板122的延伸方向相交，介质基板120、第一天线阵列130和第二天线阵列140可形成一异型天线，该异型天线可根据电子设备10的电路板400的形状进行设计，从而该异型天线对电子设备10的电路板400没有改进需求，异形天线的适应性更好；并且，由于第二天线阵列140设置在与第一子基板121相互连接的第二子基板122上，第二天线阵列140可以通过第二子基板122和第一子基板121固定于安装物体上，可以降低第二天线阵列140的安装难度。
其中，请参考图6和图7，图6为本申请实施例提供的天线装置的第二种结构示意图，图7为本申请实施例提供的天线装置的第三种结构示意图。介质基板120除了包括第一子基板121、第二子基板122外还可以包括一个或多个第三子基板123，相应的，天线装置100除了包括第一天线阵列130和第二天线阵列140外还可以包括第三天线阵列170。
可以理解的是，每一个第三子基板123的延伸方向可以与第一子基板121 的延伸方向相交，也可与第二子基板122的延伸方向相交，从而，任意一个第三子基板123与第一子基板121、第二子基板122不共面。
可以理解的是，如图6、图7所示，当第三子基板123垂直于或近似垂直第一子基板121和第二子基板122时，第一子基板121、第二子基板122和第三子基板123可以形成X-Y-Z坐标系。
当然，第三子基板123也可以不垂直于第一子基板121、第二子基板122，例如，第三子基板123与第一子基板121、第二子基板122之间的夹角可为锐角或钝角。本申请实施例对第三子基板123、第一子基板121、第二子基板122的具体位置关系不进行限定，凡是满足第三子基板123的延伸方向与第一子基板121的延伸方向相交的方案均在本申请的保护范围内。
可以理解的是，介质基板120的第一子基板121、第二子基板122可以为一体成型结构。第一子基板121、第二子基板122、一个或多个第三子基板123也可以为一体成型结构。
其中，第三天线阵列170的数量可以不大于一个或多个第三子基板123的数量，每一个第三天线阵列170可以设置于一个第三子基板123上。
可以理解的是，如图6所示，当第三天线阵列170的数量为一个或多个且等于第三子基板123的数量时，一个第三天线阵列170可与一个第三子基板123对应，每一个第三子基板123上均可以设置一个第三天线阵列170。
再例如，如图7所示，当第三子基板123的数量为一个时，第三天线阵列170的数量可以少于第三子基板123的数量而为零，此时，天线装置100可不包括第三天线阵列170，此时，第三子基板123上可不设置第三天线阵列170，第三子基板123可作为走线软板实现馈电点150与馈源110的电连接。
本申请实施例的天线装置100，当介质基板120包括的子基板的数量多于天线阵列的数量时，介质基板120存在部分子基板可以不设置天线阵列。介质基板120上未设置天线阵列的子基板可以起到装配作用、设置馈线网络作用等。
需要说明的是，本申请实施例的第三天线阵列170和第三子基板123的具体数量可不局限于上述举例，本申请实施例对此不进行具体限定。
请结合图6并请参考图8，图8为图6所述的天线装置的一种辐射方向示意图。当天线装置100的第三天线阵列170设置于第三子基板123时，第三天线阵列170可以与馈源110直接或间接电连接，第三天线阵列170也可以与馈源110通过耦合连接的方式实现馈电，或者，第三天线阵列170也可以与第一 天线阵列130或第二天线阵列140耦合连接实现馈电，以使得第三天线阵列170可以传输第三无线信号并具有第三辐射方向A3。
可以理解的是，第三辐射方向A3可以由介质基板120的第三子基板123向外延伸并形成第三辐射区域。第三辐射方向A3可以是第三天线阵列170的主辐射方向。
可以理解的是，由于第三子基板123的延伸方向与第一子基板121、第二子基板122的延伸方向相交，进而，第三辐射区域的大部分区域与第一辐射区域、第二辐射区域的大部分区域不重叠，第三天线阵列170的第三辐射方向A3不同于第一天线阵列130的第一辐射方向A1、也不同于第二天线阵列140的第二辐射方向A2。
本申请实施例的天线装置100，天线装置100包括具有第一辐射方向A1的第一天线阵列130、具有第二辐射方向A2的第二天线阵列140和具有第三辐射方向A3的第三天线阵列170，天线装置100包括三个不同的辐射方向，天线装置100覆盖的信号方向更广，可以提高天线装置100的辐射性能。
其中，请参考图9和图10，图9为本申请实施例提供的天线装置的第四种结构示意图，图10为图9所示的主板的一种结构示意图。天线装置100还可以包括主板180。
如图10所示，主板180可以包括相对设置的第一面181和第三面183，以及设置于第一面181、第三面183之间的第二面182、第四面184、第五面185和第六面186。第二面182、第四面184、第五面185和第六面186的延伸方向可与第一面181、第三面183的延伸方向均相交，以使得第二面182、第四面184、第五面185和第六面186与第一面181、第三面183不共面。
可以理解的是，第二面182、第四面184、第五面185和第六面186可以与第一面181、第三面183直接或间接连接，此时，主板180可为矩形的薄板结构。
可以理解的是，主板180也可以为其他形状的结构，例如但不限于棱柱、五边体、六边体、多边体等，主板180还可以包括更多的面，例如第七面、第八面……。本申请对主板180的具体结构不进行限定。
可以理解的是，主板180可以承载介质基板120及天线阵列，主板180可以但不限于是电子设备10的中框300的承载板的至少一部分、电子设备10的天线支架的至少一部分、电子设备10的电路板400的至少一部分。例如， 电子设备10的电路板400可以包括天线装置100的主板180。
需要说明的是，本申请实施例对主板180的具体结构不进行限定，凡是能承载介质基板120及天线阵列的结构均可在本申请实施例的保护范围内。
其中，如图9所示，主板180的第一面181与第二面182相互连接，且第二面182的延伸方向可与第一面181的延伸方向相交，此时，介质基板120的第一子基板121可以连接于主板180的第一面181，例如，第一子基板121的下表面可贴合并连接于第一面181；介质基板120的第二子基板122可以连接于主板180的第二面182，例如第二子基板122的内表面可贴合并连接于第二面182上。
可以理解的是，当介质基板120还包括一个或多个第三子基板123时，每一个第三子基板123可以连接于主板180的区别于第一面181、第二面182的其他适宜的面上，例如第三子基板123可以连接于第四面184、第五面185、第六面186……。
可以理解的是，主板180上与第三子基板123连接的面的延伸方向可以与第一面181、第二面182的延伸方向相交，以使得当第三阵列天线170设置于该第三子基板123时，第三天线阵列170的辐射方向不同于第一天线阵列130、第二天线阵列140的辐射方向。
本申请实施例的天线装置100，第一天线阵列130通过第一子基板121连接于主板180的第一面181，第二天线阵列140通过第二子基板122连接于主板180的第二面182上，第一天线阵列130和第二天线阵列140在主板180的厚度方向上的尺寸较小，可以减少天线装置100的剖面高度，实现天线装置100的小型化；并且，由于主板180的第二面182在主板180厚度方向上的尺寸较小，第二面182上较难以固定天线辐射体，而本申请实施例中由于第二子基板122与第一子基板121相互连接，从而，第二天线阵列140可以通过第二子基板122和第一子基板121连接于主板180的第二面182，可以降低第二天线阵列140的安装难度。
基于上述天线装置100的结构，请参考图11，图11本申请实施例提供的天线装置的第五种结构示意图。第一天线阵列130、馈电点150可通过第一子基板121连接于主板180的第一面181，馈源110可以设置于主板180的第三面183，馈源110可以与第一天线阵列130设置于主板180的异面。
如图10所示，主板180上还可以设置有贯穿第一面181和第三面183的 金属镀孔187，该金属镀孔187的孔壁上可以进行金属镀操作，以使得连接于第一面的馈电点150可以通过金属镀孔187的孔壁与第三面183的馈源110电连接，从而实现馈源110与第一天线阵列130、第二天线阵列140的电连接。

本申请实施例的天线装置100，馈源110与第一天线阵列130设置于主板180的异面，第一天线阵列130可以与馈源110正对设置并可通过金属镀孔187实现直接或间接连接，从而，可以降低第一天线阵列130与馈源110的电连接难度，减少二者电连接的布线数量。
其中，请参考图12，图12为本申请实施例提供的天线装置的第六种结构示意图，第一天线阵列130、馈电点150和馈源110可以均连接于主板180的第一面181，馈源110与第一天线阵列130可以设置于主板180的同一面。
可以理解的是，第一天线阵列130与馈源110可以间隔设置，以使得第一天线阵列130与馈源110可以连接于主板180的第一面181的不同区域。

其中，介质基板120也可以同时包括柔性材料与刚性材料。示例性的，请参考图14，图14为本申请实施例提供的天线装置的第八种结构示意图。介质基板120的第一子基板121可以包括层叠设置的基底层1212和第一柔性层1211，第二子基板122可以包括第二柔性层1221。
