在介绍本申请实施方式提供的天线组件10之前,先介绍天线组件10的两种结构,请一并参阅图1、图2及图3,图1为一实施方式提供的天线组件的结构示意图;图2为图1中提供的天线组件的方向图; 图3为图2中天线组件的3D方向图沿XOY截面的方向图。在本实施方式中,所述天线组件10包括辐射体120、地系统110及馈源130。所述辐射体120与所述地系统110间隔设置。所述馈电点1211电连接至所述馈源130,所述接地点1212电连接至所述地系统110,以使得所述辐射体120在所述地系统110上激励起第一电流(也称为第一模对应的电流,如图1中虚线所示)。
所述辐射体120具有接地端及自由端,所述接地端为具有所述接地点1212的端部,所述自由端为与所述接地端向背的端部。所述第一电流的方向为自所述接地端指向所述自由端的方向。在图示视角,所述第一电流的流向为纵向,换而言之,所述第一电流也称为纵向电流。
请一并参阅图4、图5及图6,图4为另一实施方式提供的天线组件的结构示意图;图5为图4中提供的天线组件的方向图;图6为图5中天线组件的3D方向图沿XOY截面的方向图。在本实施方式中,所述天线组件10包括辐射体120、地系统110及馈源130。所述辐射体120具有馈电点1211及接地点1212。所述辐射体120沿横向设置,且所述辐射体120与所述地系统110间隔设置。所述馈电点1211电连接至所述馈源130,所述接地点1212电连接至所述地系统110,以使得所述辐射体120在所述地系统110上激励起第二电流(也称为第二模对应的电流,如图4中虚线所示)。
所述辐射体120具有接地端及自由端,所述接地端为具有所述接地点1212的端部,所述自由端为与所述接地端向背的端部。所述第二电流的方向为自所述接地端指向所述自由端的方向。在图示视角,所述第二电流的方向为横向,换而言之,所述第二电流也称为横向电流。
结合图1至图3,以及图4至图6可见,这两个天线组件10激励起的模式不同,方向图差异较大。可以看出两个天线组件10的方向图中的最大辐射方向及零点均在不同方向。此外,由两个天线组件10的方向图可见,两个天线组件10的全向性较差。
请一并参阅图7、图8及图9,图7为本申请一实施方式提供的天线组件的示意图;图8为图7中提供的天线组件的3D方向图与图1及图4中提供的天线组件的3D方向图对比示意图;图9为图8中天线组件沿XOY截面的方向图。所述天线组件10包括地系统110、辐射体120及馈源130。所述辐射体120包括相连的第一辐射部121及第二辐射部122。所述第一辐射部121与所述地系统110相对且间隔设置,所述第二辐射部122与所述地系统110相对且间隔设置,所述第一辐射部121具有馈电点1211,所述第一辐射部121及所述第二辐射部122中的至少一者具有接地点1212,所述接地点1212电连接至所述地系统110。所述馈源130电连接至所述馈电点1211,以使得所述第一辐射部121收发第一电磁波信号,所述第二辐射部122收发第二电磁波信号,其中,所述第一电磁波信号与所述第二电磁波信号均支持预设频段,且所述第一电磁波信号与所述第二电磁波信号的方向图互补。
需要说明的是,本实施方式中,以第一辐射部121收发的电磁波信号命名为第一电磁波信号,所述第二辐射部122收发的电磁波信号命名为第二电磁波信号,只是为了方便理解而进行的命名,实际上,所述第一辐射部121及所述第二辐射部122相连,且电连接一个馈源130,因此,所述辐射体120形成的天线为一个天线,而并非两个天线。换而言之,所述一个天线收发所述预设频段的电磁波信号。
在本实施方式中,第一辐射部121及第二辐射部122弯折相连。所述第一辐射121与所述第二辐射部122之间的角度为90°,或者近似为90°(比如,80°至100°)。
在本实施方式的示意中,以所述地系统110为长方形且所述地系统110横向设置为例进行示意,可以理解地,不应当理解为对本申请实施方式提供的天线组件10的限定。在一实施方式中,所述地系统110为导电板材,比如,所述地系统110可以为但不仅限于为导电的金属板,比如,铝镁合金,或铜、或金、或银等。

所述馈源130用于产生激励信号,所述馈源130电连接至所述馈电点1211,以将所述激励信号经由所述馈电点1211传输至所述第一辐射部121。所述预设频段可以为但不仅限于为Wifi 2.4GHz频段,Wifi 5GHz频段,或者蓝牙频段,或者长期演进技术(Long Term Evolution,LTE)频段,或新空口(New Radio,NR)频段,在本实施方式中不做限定。其中,在本实施方式中,以所述预设频段为Wifi 2.4GHz频段为例进行说明,其中,所述Wifi 2.4GHz频段的中心频点为2.4GHz,频段范围为2.4GHz至2.5GHz。
所述激励信号经由所述馈电点1211传输至所述第一辐射部121,所述第一辐射部121预设频段的第一电磁波信号;所述第二辐射部122收发预设频段的第二电磁波信号,即,所述第一辐射部121于所述第二辐射部122均用于收发同一预设频段的电磁波信号。所述第一电磁波信号的方向图与所述第二电磁波信号的方向图互补,从而使得第一电磁波信号及第二电磁波信号形成的方向图为互补全向性方向图,即,所述天线组件10成为全向天线或类全向性天线。
请参阅图8,图8(a)为图1中提供的天线组件的3D方向图,图8(b)为图4中提供的天线组件的3D方向图,图8(c)为图7中提供的天线组件的3D方向图。由图8(a)至图8(c)可见,图7中的天线组件10对应的图8(c)中的3D方向图比图1中的天线组件10对应的图8(a)的3D方向图及图4中的天线组件10对应的图8(b)中3D方向图更趋向于全向天线的方向图,且天线零点数量明显的少于图1及图4及其实施方式对应的天线组件10的天线零点数量。
此外,请参阅图9,图9中曲线①为图8(a)中天线组件10的3D方向图沿着XOY界面的方向图,换而言之,曲线①对应图1的天线组件10的方向图;曲线②为图8(b)中天线组件10的3D方向图沿XOY截面的方向图,换而言之,曲线②为对应图4的天线组件10的方向图;曲线③为图8(c)中天线组件10的3D方向图沿XOY截面的方向图,换而言之,曲线③对应图7的天线组件的方向图。由图9中曲线①、曲线②及曲线③可见,曲线③中的方向图更趋向于全向天线的方向图,且天线零点数量明显的少于曲线①及曲线②的天线零点数量。
综上所述,本申请实施方式提供的天线组件10,通过将馈源130电连接至第一辐射部121的馈电点1211,使得第一辐射部121收发预设频段的第一电磁波信号,所述第二辐射部122收发所述预设频段的第二电磁波信号,所述第一电磁波信号的方向图与所述第二电磁波信号的方向图互补,从而使得所述天线组件10为全向性天线,或者为类全向性天线。当所述天线组件10与其天线组件10进行通信时的全向性较好。当所述天线组件10在应用时,无论所述天线组件10在任何角度,利用所述天线组件10与其他设备进行通信时,均具有较好的一致性。换而言之,本申请实施方提供的天线组件10与其他设备的天线组件进行通信时的通信效果较好。
此外,相关技术中为了使得天线组件10收发的电磁波信号较好的全性向,通常利用天线组件10的独立的两个天线来实现同一频段且不同方向图的电磁波信号的收发。对于两个独立的天线而言,每个天线均需要馈源130,每个馈源130均电连接一个辐射体120,且不同的馈源130电连接至不同的辐射体120,因此,导致天线组件10的较大。此外,当利用天线组件10的两个天线收发同一频段的电磁波信号时,还需要考虑两个天线的隔离度,比如,设计隔离结构使得两个天线之间具有较好的隔离度。由此可见,利用天线组件10中独立的两个天线实现同一频段且不同方向图的电磁波信号的收发时占用的空间较大。本申请实施方式提供的天线组件10,利用一个辐射体120的两个辐射部来实现预设频段的电磁波信号的收发,无需设置两个馈源130,且无需隔离结构,因此,本申请实施方式提供的天线组件10的结构较为紧凑。
请一并参阅图7及图10,图10为图7中提供的天线组件的中电流的分布示意图。由图10可见,所述第一辐射部121在所述地系统110上激励起第一模,所述第二辐射部122在所述地系统110上激励起第二模,其中,所述第一模与所述第二模为彼此正交的模式。在本实施方式中,所述第一模对应第一 电流,所述第二模对应第二电流。在本实施方式中,以所述第一模对应的第一电流为纵向电流,所述第二模对应的第二电流为横向电流为例进行说明。在其他实施方式中,所述第一电流及所述第二电流的流向和所述天线组件10的摆放角度相关。当所述天线组件10顺时针或逆时针旋转90°,那么,所述第一模对应的第一电流为横向电流,所第二模对应的第二电流为纵向电流。当所述天线组件10旋转其他度数时,所述第一模对应的第一电流的流向是倾斜的,所述第二模对应的第二电流是倾斜的,只要满足所述第一模与所述第二模为彼此正交的模式即可。相应地,所述第一电流的流向与所述第二电流的流向垂直。由于本申请实施方式提供的天线组件10具有彼此正交的第一模及第二模,因此,所述天线组件10的方向图为全向性天线的方向图,或者更趋向于全向天线的方向图。即,所述天线组件10成为全向天线或类全向性天线。此外,本申请实施方式提供的天线组件10的天线零点数量明显的少于传统天线组件10中的天线零点数量。
请进一步参阅图11,图11为图7提供的天线组件的S参数仿真示意图。在本示意图中,横轴为频率,单位为GHz,纵轴为S参数,单位为dB。所述第一电磁波信号具有第一谐振频点,所述第二电磁波信号具有第二谐振点,其中,所述第一谐振频点与所述第二谐振频点不同。
在本实施方式中,所述天线组件10在所述预设频段产生两个谐振,其中,曲线中的两个凹陷处为所述预设频段的两个谐振频点,其中一个为第一谐振频点(图11中位于点1右边的A点),另一个为第二谐振频点(图11中点3左边的B点)。在本实施方式中,所述第一谐振频点小于所第二谐振频点。换而言之,所述第一谐振频点为第一辐射部121产生,所述第二谐振频点为第二辐射部122产生。本仿真示意图中,S参数的曲线中位于所述第一谐振频点及所述第二谐振频点的频段,既有第一模又有第二模,因此,使得所述天线组件10收发的预设频段的电磁波信号时能够叠加形成全向性较好的方向图。在其他实施方式中,所述第一谐振频点大于所述第二谐振频点,只要满足所述第一谐振频点与所述第二谐振频点不同即可。
请进一步参阅图7至图11,所述第二辐射部122具有连接点1213,所述天线组件10还包括匹配电路140。所述匹配电路140电连接至所述连接点1213,所述匹配电路140用于调整所述第二谐振频点。
所述匹配电路140用于调整所述第二谐振频点,使得所述第二谐振频点靠近或背离所述第一谐振频点。具体地,所述匹配电路140用于调整所述第二谐振频点,使得所述第二谐振频点与所述第一谐振频点的距离适中,即,所述第一谐振频点及所述第二谐振频点不能离得太近,也不能离得太远,进而使得所述天线组件10具有较好的通信性能。
此外,请进一步参阅图12,图12为本申请另一实施方式提供的天线组件的示意图。所述天线组件10还包括匹配单元160,所述匹配单元160用于调整所述第一谐振频点,使得所述第一谐振频点靠近或背离所述第一谐振频点。具体地,所述匹配单元160用于调整所述第一谐振频点,使得所述第一谐振频点与所述第二谐振频点的距离适中,即,所述第一谐振频点及所述第二谐振频点不能离得太近,也不能离得太远,进而使得所述天线组件10具有较好的通信性能。
请进一步参阅图13,图13为图7中所示的天线组件中各个部件的尺寸示意图。所述第一辐射部121为第一长度,所述第二辐射部122的长度为第二长度,其中,第一长度与所述第二长度之差的绝对值L0满足:3mm≤L0≤5mm。
具体地,所述第一辐射部121的长度为第一长度L1,所述第二辐射部122的长度为第二长度L2,在一实施方式中,所述第一长度L1大于或等于所述第二长度L2;在另一实施方式中,所述第一长度L1小于所述第二长度L2。只要L1-L2的绝对值L0满足:3mm≤L0≤5mm即可。
当所述第一长度与所述第二长度之差的绝对值L0满足:3mm≤L0≤5mm时,可使得所述第一辐射部121的长度与所述第二辐射部122的长度相差较小,所述第一辐射部121收发的第一电磁波信号及所述第二辐射部122收发的第二电磁波信号具有相同的所述预设频段。此外,也无需设计复杂的匹配电路140就能够使得所述第一辐射部121及所述第二辐射部122均能够支持所述预设频段的电磁波信号。
请进一步参阅图7,在本实施方式中,所述地系统110具有第一边111及第二边112。所述第一边111与所述第一辐射部121相对且间隔设置。所述第二边112与所述第一边111弯折相连,且所述第二边112与所述第二辐射部122相对且间隔设置。
所述第一边111与所述第一辐射部121相对且间隔设置,所述第二边112与所述第一边111弯折相连,且所述第二边112与所述第一辐射部121相对且间隔设置,由此可见,所述第一辐射部121及所述第二辐射部122设置于所述第一边111与所述第二边112相连处。因此,当所述第一辐射部121激励起所述地系统110的第一电流时,可充分利用所述地系统110在所述第一边111的延伸方向上的长度;当所述第二辐射部122激励起所述地系统110的第二电流时,可充分利用所述地系统110在所述第二边112的延伸方向的长度,对于收发同样预设频段的电磁波信号的天线组件10而言,本申请实施方式提供的天线组件10能够充分利用地系统110的尺寸,便于所述地系统110的小型化。
在本实施方式中,所述第一边111的长度大于所述第二边112的长度。为了后续仿真图中在地系统110中第一辐射部121及第二辐射部122的清晰示意,在图7中所述第一边111的长度并未展示完整。
换而言之,第一辐射部121对应所述地系统110的长边设置,所述第二辐射部122对应所述地系统110的短边设置。在其他实施方式中,所述第一边111的长度小于所述第二边112的长度。或者,在其他实施方式中,所述第一边111的长度等于所述第二边112的长度。
在本实施方式中,所述第一边111直接与所述第二边112弯折相连,且所述第一边111垂直于或近似垂直于所述第二边112,所述第一辐射部121及所述第二辐射部122中的至少一者具有的所述接地点1212电连接至所述第一边111或第二边112。在其他实施方式中,所述第一边111与所述第二边112通过圆弧倒角相连,所述第一边111垂直于或近似垂直于所述第二边112,所述第一辐射部121及所述第二辐射部122中的至少一者具有的接地点1212电连接至所述第一边111或第二边112。
当所述第一边111垂直于所述第二边112时,可更有利于激励起彼此正交的第一模及第二模。
请参阅图7,在图7及相关描述中所示的实施方式中,所述第一辐射部121具有所述接地点1212,所述接地点1212设置于所述第一辐射部121与所述第二辐射部122连接的一端。
在本实施方式中,所述第二辐射部122通过连接件150电连接至所述地系统110。所述连接件150连接至所述第一辐射部121的接地点1212之外,还连接了所述第一辐射部121的较多的部位以及地系统110中较多的部位。所述连接件150与所述第一辐射部121之间可视为面连接,所述连接件150与所述地系统110之间可视为面连接。如此,一方面实现将第一辐射部121电连接,另外一方面可使得所述第一辐射部121与所述地系统110之间具有较好的连接强度。可以理解地,所述连接件150与所述第一辐射部121及所述地系统110之间也可以为点连接。
需要说明的是,在图7中的天线组件10中除了示意所述地系统110、所述辐射体120、所述馈源130、所述匹配电路140、及所述连接件150之外,还示意了其他结构(如顶部右侧,以及右侧的相应结构),可以理解地,所述其他结构的示意不应当构成对本申请实施方式提供的天线组件10的限定,在其他实施方式中,也可不包括所述其他结构。
请参阅图14,图14为本申请另一实施方式提供的天线组件的示意图。在本实施方式中,所述第二辐射部122具有所述接地点1212,所述接地点1212设置于所述第二辐射部122与所述第一辐射部121连接的一端。在本实施方式中,所述第二辐射部122通过连接件150连接至所述地系统110。
请参阅图15,图15为本申请又一实施方式提供的天线组件的示意图。在本实施方式中,所述第一辐射部121及所述第二辐射部122均具有所述接地点1212,所述第一辐射部121的接地点1212设置于所述第一辐射部121与所述第二辐射部122连接的一端,所述第二辐射部122的接地点1212位于所述第二辐射部122与所述第一辐射部121连接的一端。
由图7、图14及图15及其相关实施方式可见,所述第一辐射部121及所述第二辐射部122中的至少一者具有接地点1212,可使得所述辐射体120的接地的位置可灵活设计。
请一并参阅图16及图17,图16为本申请再一实施方式提供的天线组件的示意图;图17为图16中所示的天线组件的地系统的电流示意图。所述地系统110具有圆弧形周侧边113,所述第一辐射部121与所述第二辐射部122设置于所述周侧边113的周缘,且均与所述周侧边113间隔设置。
在本实施方式中,所述地系统110的形状为圆形、或类圆形、或椭圆形或类椭圆形。所述辐射体120的形状可以为弧形或类弧形。在本实施方式的示意图中,以所述辐射体120为半圆弧形为例进行示意,可以理解地,不应当理解为对本申请实施方式提供的天线组件10的限定。
本申请实施方式提供的天线组件10的上述形态可适用于圆形或类圆形、或椭圆形或类椭圆形的电子设备1(比如,手表,或手环),便于与电子设备1的外形结构相适应。
结合前面各个实施方式提供的天线组件10,所述第一辐射部121的各个部位与所述地系统110之间的间隙相等;所述第二辐射部122的各个部位与所述地系统110之间的间隙相等。
所述第一辐射部121的各个部位与所述地系统110之间的间隙相等,可使得所述第一辐射部121在所述地系统110在纵向上各个部分激励起的第一电流Ia的强度较为均匀;所述第二辐射部122的各个部位与所述地系统110之间的间隙相等,可使得所述第二辐射部122在所述地系统110在横向上各个部分激励起的第二电流Ib的强度较为均匀;进而使得所述天线组件10收发的预设频段的电磁波信号具有较好的全向性。
请参阅图13,在一实施方式中,所述第一辐射部121与所述地系统110之间的间隙d1满足:1mm≤d1≤10mm。所述第二辐射部122与所述地系统110之间的间隙d2满足:1mm≤d2≤10mm。
所述间隙d1可以为但不仅限于为1mm,或2mm,或3mm,或4mm,或5mm,或6mm,或7mm,或8mm,或9mm,或10mm。
所述间隙d2可以为但不仅限于为1mm,或2mm,或3mm,或4mm,或5mm,或6mm,或7mm,或8mm,或9mm,或10mm。所述间隙d1与所述间隙d2可以相等也可以不相等。
当所述第一辐射部121与所述地系统110之间的间隙d1满足:1mm≤d1≤10mm时,可使得所述第一辐射部121具有较大的净空,使得所述天线组件10能够更好的收发所述预设频段的第一电磁波信号;相应地,当所述第二辐射部122与所述地系统110之间的间隙d2满足:1mm≤d2≤10mm时,可使得所述第二辐射部122具有较大的净空,使得所述天线组件10能够更好的收发所述预设频段的第二电磁波信号进而具有较好的通信性能。
结合前面实施方式提供的天线组件10。所述天线组件10包括地系统110、辐射体120及馈源130。所述辐射体120包括相连的第一辐射部121及第二辐射部122。所述第一辐射部121及所述第二辐射部122分别与所述地系统110间隔设置,所述第一辐射部121及所述第二辐射部122中的至少一者具有接地点1212,所述接地点1212电连接至所述地系统110。所述馈源130电连接至所述第一辐射部121,以使得所述第一辐射部121在所述地系统110上激励起第一模,所述第二辐射部122在所述地系统110上激励起第二模,其中,所述第一模及所述第二模为彼此正交的模式,且所述第一模及所述第二模均支持预设频段的电磁波信号。
本申请实施方式提供的天线组件10,通过将馈源130电连接至第一辐射部121,使得第一辐射部121在所述地系统110上激励起第一模,所述第二辐射部122在地系统110上激励起第二模,其中,所述第一模及所述第二模为彼此正交的模式,且所述第一模及所述第二模均支持预设频段的电磁波信号,因此,所述第一模对应的第一电磁波信号的方向图与所述第二模对应的第二电磁波信号的方向图互补,从而使得所述天线组件10为全向性天线,或者为类全向性天线。当所述天线组件10与其天线组件10进行通信时的全向性较好,进而使得所述天线组件10与其他天线组件10进行通信时的通信效果较好。
此外,相关技术中为了使得天线组件10收发的电磁波信号较好的全性向,通常利用天线组件10的独立的两个天线来实现同一频段且不同方向图的电磁波信号的收发。对于两个独立的天线而言,每个天线均需要馈源130,每个馈源130均电连接一个辐射体120,且不同的馈源130电连接至不同的辐射体120,因此,导致天线组件10的较大。此外,当利用天线组件10的两个天线收发同一频段的电磁波信号时,还需要考虑两个天线的隔离度,比如,设计隔离结构使得两个天线之间具有较好的隔离度。由此可见,利用天线组件10中独立的两个天线实现同一频段且不同方向图的电磁波信号的收发时占用的空间较大。本申请实施方式提供的天线组件10,利用一个辐射体120的两个辐射部来实现预设频段的电磁波信号的收发,无需设置两个馈源130,且无需隔离结构,因此,本申请实施方式提供的天线组件10的结构较为紧凑。
进一步地,所述地系统110具有弯折相连的第一边111及第二边112,所述第一辐射部121对应所述第一边111设置,所述第二辐射部122对应所述地系统110的第二边112设置,所述第一辐射部121在所述地系统110上激励起第一模对应的第一电流,所述第二辐射部122在所述地系统110上激励起第 二模对应的第二电流,其中,所述第一电流的方向与所述第二电流的方向正交。在本实施方式中,所述第一模对应第一电流,所述第二模对应第二电流。在本实施方式中,以所述第一模对应的第一电流为纵向电流(图示视角),所述第二模对应的第二电流为横向电流(图示视角)为例进行说明。具体地,所述辐射体120具有接地端及自由端,所述接地端为具有所述接地点1212的端部,所述自由端为与所述接地端向背的端部。在本实施方式中,将所述自由端标记为120a,将所述接地端标记为120b。所述第一电流的方向为自所述接地端120b指向所述自由端120a的方向。所述第二电流的方向为垂直于所述第一电流的方向或大致垂直与所述第一电流的方向。在其他实施方式中,所述第一电流及所述第二电流的流向和所述天线组件10的摆放角度相关。当所述天线组件10顺时针或逆时针旋转90°,那么,所述第一模对应的第一电流为横向电流,所第二模对应的第二电流为纵向电流。当所述天线组件10旋转其他度数时,所述第一模对应的第一电流的流向是倾斜的,所述第二模对应的第二电流是倾斜的,只要满足所述第一模与所述第二模为彼此正交的模式即可。相应地,所述第一电流的流向与所述第二电流的流向垂直。
所述第一边111与所述第一辐射部121相对且间隔设置,所述第二边112与所述第一边111弯折相连,且所述第二边112与所述第一辐射部121相对且间隔设置,由此可见,所述第一辐射部121及所述第二辐射部122设置于所述第一边111与所述第二边112相连处。因此,当所述第一辐射部121激励起所述地系统110的第一电流时,可充分利用所述地系统110在所述第一边111的延伸方向上的长度;当所述第二辐射部122激励起所述地系统110的第二电流时,可充分利用所述地系统110在所述第二边112的延伸方向的长度,对于收发同样预设频段的电磁波信号的天线组件10而言,本申请实施方式提供的天线组件10能够充分利用地系统110的尺寸,便于所述地系统110的小型化。
进一步地,所述第一辐射部121具有馈电点1211。所述馈电点1211设置于所述接地点1212背离所述第二辐射部122的一端,所述纵向电流由所述接地点1212朝向所述馈电点1211的方向流动,所述横向电流由所述第二辐射部122邻近所述第一辐射部121的一端朝向所述第二辐射部122背离所述第一辐射部121的一端的方向流动。
所述馈电点1211设置于所述接地点1212背离所述第二辐射部122的一端,所述第一电流由所述接地点1212朝向所述馈电点1211的方向流动,所述第二电流由所述第二辐射部122邻近所述第一辐射部121的一端朝向所述第二辐射部122背离所述第一辐射部121的一端的方向流动,由此可见,所述第一辐射部121及所述第二辐射部122设置于所述第一边111与所述第二边112相连处。因此,当所述第一辐射部121激励起所述地系统110的第一电流时,可充分利用所述地系统110在所述第一边111的延伸方向上的长度;当所述第二辐射部122激励起所述地系统110的第二电流时,可充分利用所述地系统110在所述第二边112的延伸方向的长度,对于收发同样预设频段的电磁波信号的天线组件10而言,本申请实施方式提供的天线组件10能够充分利用地系统110的尺寸,便于所述地系统110的小型化。
所述第一电磁波信号具有第一谐振频点,所述第二电磁波信号具有第二谐振点,其中,所述第一谐振频点与所述第二谐振频点不同。

所述第二辐射部122具有连接点1213,所述天线组件10还包括匹配电路140。所述匹配电路140电连接至所述连接点1213,所述匹配电路140用于调整所述第二谐振频点。
所述匹配电路140用于调整所述第二谐振频点,使得所述第二谐振频点靠近或背离所述第一谐振频点,具体地,所述匹配电路140用于调整所述第二谐振频点,使得所述第二谐振频点与所述第一谐振 频点的距离适中,即,所述第一谐振频点及所述第二谐振频点不能离得太近,也不能离得太远,进而使得所述天线组件10具有较好的通信性能。
请一并参阅前面附图,所述第一辐射部121具有电连接至所述馈源130的馈电点1211,所述第二辐射部122具有电连接匹配电路140的连接点1213。所述地系统110具有圆弧形周侧边113,所述第一辐射部121及所述第二辐射部122均设置于所述周侧边113的周缘,所述第一辐射部121在所述地系统110上激励起第一模对应的第一电流,所述第二辐射部122在所述地系统110上激励起第二模对应的第二电流,所述第一电流的方向与所述第二电流的方向正交。
