本申请涉及电子技术领域，尤其涉及一种天线模组及电子设备。
背景技术
毫米波具有高载频、大带宽的特性，是实现5G超高数据传输速率的主要手段。由于毫米波频段的电磁波剧烈的空间损耗，利用毫米波频段的无线通信系统需要采用相控阵的架构。通过移相器使得各个阵元的相位按一定规律分布，从而形成高增益波束，并且通过相移的改变使得波束在一定空间范围内扫描。为了满足带宽需求，模组的天线层部分需要较厚的介质层，由于高密度互连(High Density Interconnector，HDI)工艺需要保证叠层的对称性，从而导致总的天线模组厚度较大。

请参阅图1、图2、图3和图4，为了便于清楚的观察到天线模组的内部结构，图2、图3和图4中仅以一个天线模组为例进行示例，且将介质基板100省略。本申请实施例提供的天线模组10包括介质基板100、贴片阵列200、馈地层300、馈地部400和馈电部500，所述贴片阵列200承载于所述介质基板100；所述馈地层300承载于所述介质基板100，且所述馈地层300与所述贴片阵列200间隔设置；所述馈地部400电连接于所述贴片阵列200和所述馈地层300之间，所述馈地部400包括第一部分401、第二部分402、第三部分403、第四部分404和第五部分405，所述第一部分401、所述第二部分402和所述第三部分403依次弯折相连，所述第一部分401、所述第四部分404和所述第五部分405依次弯折相连，所述第一部分401电连接于所述贴片阵列200，所述第三部分403电连接于所述馈地层300，所述第五部分405电连接于所述馈地层300；所述馈电部500用于馈入电流信号，所述电流信号耦合至所述贴片阵列200，以激发所述贴片阵列200谐振于第一频段，所述电流信号耦合至所述馈地部400，以激发所述馈地部400谐振于第二频段。
其中，所述第一频段可以不同于所述第二频段，从而可以实现双频段信号的收发，使得天线模组10可以应用于不同场景。所述第一频段和所述第二频段也可以相同，此时，可以实现单频段信号的收发，有助于增强天线模组10收发射频信号的强度。
其中，天线模组10可以为毫米波模组。天线模组10用于收发预设频段的毫米波射频信号。所述天线模组10可以采用高密度互连(High Density Interconnector,HDI)工艺或者是IC载板工艺加工形成。所述介质基板100采用多层介质板压合形成，贴片阵列200、馈地层300、馈地部400和馈电部500均承载于介质基板100上，所述馈地层300和所述贴片阵列200间隔设置，所述馈地部400连接于馈地层300和贴片阵列200之间，所述馈地部400为弯折结构，可以延长电流传输路径，进而提升射频信号的带宽。同时，可以减小天线模组10的厚度。
当馈电部500馈入电流信号时，电流信号耦合至贴片阵列200，可以使得贴片阵列200谐振于第一频段，即使得贴片阵列200产生第一频段的射频信号。电流信号耦合至馈地部400，可以使得馈地部400谐振于第二频段，即使得馈地部400产生第二频段的射频信号。其中，当所述第一频段不同于所述第二频段时，第一频段可以为高频信号，第二频段可以为低频信号。进一步的，所述第一频段的最小值大于所述第二频段的最大值，所述第一频段和所述第二频段共同构成预设频段，所述预设频段至少包括3GPP毫米波全频段。
根据3GPP TS 38.101协议的规定，5G主要使用两段频率：FR1频段和FR2频段。FR1频段的频率范围是450MHz～6GHz，又叫sub-6GHz频段；FR2频段的频率范围是24.25GHz～52.6GHz，通常叫它毫米波(mm Wave)。3GPP 15版本规范了目前5G毫米波频段如下：n257(26.5～29.5GHz)，n258(24.25～27.5GHz)，n261(27.5～28.35GHz)和n260(37～40GHz)。当所述第一频段不同于所述第二频段时，第一频段可以为毫米波频段，此时，第二频段可以为sub-6GHz频段。第一频段和第二频段也可以均为毫米波频段，第一频段为高频毫米波频段，第二频段为低频毫米波频段。
在一种实施方式中，所述贴片阵列200构成电偶极子天线，所述馈地部400构成磁偶极子天线，所述贴片阵列200的辐射方向与所述馈地部400的辐射方向保持正交。
其中，贴片阵列200包括多个贴片单元200a，每个贴片单元200a构成一个天线辐射体。所述馈电部500延伸至邻近贴片阵列200的位置，且馈电部500延伸至邻近馈地部400的位置，从而便于使得馈电部500上的电流信号耦合至贴片阵列200和馈地部400上。具体的，当馈电部500的电流信号分别耦合至贴片阵列200和馈地部400时，由于耦合产生的电流信号在贴片阵列200和馈地部400上传输的方向保持正交，可以使得贴片阵列200和馈地部400辐射射频信号的方向保持正交。贴片阵列200可以构成2×2的天线阵列，可以构成2×4的天线阵列，也可以构成4×4的天线阵列。当多个所述天线辐射体构成天线阵列时，多个天线辐射体可以工作于同一频段。多个天线辐射体也可以工作于不同的频段，有助于扩大天线模组10的频段范围。
在另一种实施方式中，所述贴片阵列200在所述介质基板100上的投影位于所述馈地层300在所述介质基板100上的投影的范围内。所述馈地层300的尺寸为λ×λ，所述贴片阵列200与所述馈地层300之间的距离为λ/4，其中，所述λ为所述第一频段的中心频率与所述第二频段的中心频率的中间值对应的波长。
具体的，所述λ为固定频率的波长，所述固定频率为所述第一频率的中心频率和所述第二频率的中心频率的中间值。当馈地层300的尺寸满足λ×λ，贴片阵列200与馈地层300之间的距离满足λ/4时，天线模组10可以达到较高的辐射性能。也就是说，天线模组10的工作频率与天线模组10的结构尺寸紧密相关，不同结构尺寸的天线模组10可以影响到天线模组10的工作频率，还可以影响天线模组10的辐射性能。
在一种实施方式中，所述第二部分402与所述第四部分404保持正交，所述第三部分403和所述第五部分405保持平行，所述第二部分402与所述馈电部500保持正交或平行，可以使得天线模组10的结构强度更加稳定，且有助于实现天线极化。
请继续参阅图5、图6和图7，在另一种实施方式中，所述第二部分402和所述第四部分404均为长条状贴片，所述第二部分402包括相对设置的第一电连接端402a和第二电连接端402b，所述第四部分404包括相对设置的第三电连接端404a和第四电连接端404b，所述第一电连接端402a和所述第三电连接端404a均电连接于所述第一部分401，所述第二电连接端402b电连接于所述第三部分403，所述第四电连接端404b电连接于所述第五部分405。所述馈地部400形成立体的弯折结构，可以降低天线模组10的厚度，实现低剖面特性。且可以在贴片阵列200和馈地层500之间形成至少两条回路，当一条回路断开时，另一条回路可以继续馈电，有助于提升天线模组10的稳定性。此时，可以增强单位面积上耦合电流的强度，以便于对馈地部400收发的射频信号的频段进行调节，使得馈地部400谐振于预设频段。
在又一种实施方式中，所述第二部分402和所述第四部分404均为正方形贴片或者圆形贴片，所述第二部分402包括间隔设置的第一电连接端402a和第二电连接端402b，所述第四部分404包括间隔设置的第三电连接端404a和第四电连接端404b，且所述第一电连接端402a和所述第三电连接端404a均电连接于所述第一部分401，所述第二电连接端402b电连接于所述第三部分403，所述第四电连接端404b电连接于所述第五部分405。此时，第一电连接端402a和第三电连接端404a重叠，且各个第一电连接端402a与第一部分401之间的连接，第二电连接端402b与第三部分403之间的连接，第四电连接端404b与第五部分405之间的连接均可看作是点连接，有助于提升天线模组10馈电的灵敏度。
进一步的，所述第二部分402具有第一通孔402A，所述第四部分404具有第二通孔404A，所述第一通孔402A避开所述第一电连接端402a和所述第二电连接端402b，所述第二通孔404A避开所述第三电连接端404a和所述第四电连接端404b。具体的，在本实施方式中，第一通孔402A的数量可以为一个，也可以为多个，第二通孔404A的数量可以为一个，也可以为多个，当馈电部500上的电流信号耦合至馈地部400上时，耦合电流在馈地部400上可以沿多个传输路径传输，从而可以延长耦合电流的传 输路径，进而提升天线模组10收发射频信号的带宽。所述第一电连接端402a和所述第二电连接端402b避开所述第一通孔402A设置，所述第三电连接端404a和所述第四电连接端404b避开所述第二通孔404A设置，可以使得馈地部400与贴片阵列200以及馈地层500之间维持稳定的电连接关系。
在又一种实施方式中，所述第一部分401垂直于所述贴片阵列200所在的平面，所述第三部分403垂直于所述馈地层500所在的平面，所述第五部分405垂直于所述馈地层500所在的平面，所述第一部分401和所述第二部分402之间形成第一预设夹角，且所述第二部分402和所述第三部分403之间形成第二预设夹角，所述第一部分401和所述第四部分404之间形成第三预设夹角，且所述第四部分404和所述第五部分405之间形成第四预设夹角，所述第一预设角度的取值范围为80°～100°，所述第二预设角度的取值范围为80°～100°，所述第三预设角度的取值范围为80°～100°，所述第四预设角度的取值范围为80°～100°。可以使得馈地部400的各个部分之间保持近似的垂直弯折，有助于提升天线模组10的结构强度。
所述第一部分401、所述第二部分402和所述第三部分403弯折呈“□”形，所述第一部分401、所述第四部分404和所述第五部分405弯折呈“□”形。其中，第一部分401和第三部分403的延伸方向保持一致。具体的，所述第一部分401垂直于所述贴片阵列200所在的平面，所述第三部分403垂直于所述馈地层300所在的平面，所述第五部分405垂直于所述馈地层300所在的平面，所述第一预设角度的取值范围为80°～100°，所述第二预设角度的取值范围为80°～100°。其中，第一预设夹角可以与第二预设夹角相等，也可以不相等。在一种实施方式中，第一预设夹角为90度角，第二预设夹角为90度角。此时，贴片阵列200、第一部分401、第二部分402、第三部分403和馈地层300依次保持垂直，可以将贴片阵列200、第一部分401、第二部分402、第三部分403和馈地层300较为稳定的固定于介质基板100，且有助于提高制备天线模组10的良率。
进一步的，所述第二部分402为长条状贴片，所述第二部分402包括相对的第一电连接端402a和第二电连接端402b，所述第一部分401电连接于所述第一电连接端402a，所述第三部分403电连接于所述第二电连接端402b，所述第四部分404为长条状贴片，所述第四部分404包括相对的第三电连接端404a和第四电连接端404b，所述第一部分401电连接于所述第三电连接端404a，所述第五部分405电连接于所述第四电连接端404b。此时，馈地部400在贴片阵列200和馈地层500之间形成了两条回路，一条为第一部分401、第二部分402和第三部分403，另一条为第一部分401、第四部分404和第五部分405，可以使得贴片阵列200和馈地层500之间形成稳定的电连接关系。
本申请实施例提供的天线模组10，将电连接于贴片阵列200和馈地层300之间的馈地部400设置为立体弯折结构，可以在延长电流传输路径的同时，减小天线模组10的厚度，使得厚度达到0.85mm，具有低剖面的特性。且第一部分401、第二部分402和第三部分403依次弯折，第一部分401、第四部分404和第五部分405依次弯折，第一部分401电连接于贴片阵列200，第三部分403电连接于馈地层300，第五部分405电连接于馈地层300，在贴片阵列200和馈地层300之间形成了至少两条回路，有助于提升天线模组10工作的稳定性。且通过馈电部500向天线阵列和馈地部400耦合馈电，可以使得天线模组10工作于相同或者不同的频段，有助于实现单频或者双频段射频信号的收发。
