如图1至图8所示,本申请实施例公开一种天线组件,该天线组件可以应用在电子设备中,电子设备具体可以包括框架400和显示屏500,框架400的至少一部分与显示屏500层叠设置,当然,为了保证显示屏500和框架400之间具备相互电连接的能力,显示屏500中需要设置具备导电能力的导电部分,具体可以为金属支架530,对应地,框架400中亦包括具备导电能力的导电部分,具体可以为与显示屏500层叠设置的部分,而框架400的外周则可以为金属结构,也可以为塑料等非导电材料形成的结构。另外,电子设备还可以包括如壳体、处理器和摄像模组等器件,考虑文本简洁,此处不再一一介绍。As shown in FIG. 1 to FIG. 8 , an embodiment of the present application discloses an antenna assembly, which can be applied to an electronic device. The electronic device may specifically include a
在电子设备的天线组件中,如图1所示,天线组件包括天线110和电连接件201。在组装天线组件的过程中,可以使天线110固定连接在框架400的外周,且通过使天线110与框架400的导电部分电性连接,以使天线110与框架400之间能够形成良好的电连接关系。天线110的具体结构和形式可以根据实际需求确定,此处不作限定。另外,天线110可以采用一体成型的方式随框架400一并形成,且通过在框架400的外周边缘处刻蚀槽结构,形成可用的天线形式,这种天线110实际上是金属边框天线,框架400的连筋处相当于天线110的接地部分。或者,天线110还可以是FPC天线,在这种情况下,框架400的外周可以为塑料结构件,且这种天线110可以通过导电件与框架400的导电部分形成电连接关系,使得天线110亦可以通过框架400实现接地的目的。为了便于描述,下文均以金属边框天线为例进行说明。另外,如图1所示,天线110可以包括多支不同频段的天线,且天线110之间可以通过断缝120相互隔开,每一天线110上均设有馈点130。In an antenna assembly of an electronic device, as shown in FIG. 1 , the antenna assembly includes an
电连接件201为具备导电能力的器件,其具体可以采用金属等材料制成,其结构形式有多种,此处不作限定。在本申请的具体实施例中,电连接件201可以为螺钉或弹片等结构。在本申请的另一实施例中,电连接件201可以为导电泡棉,从而防止夹设于框架400和显示屏500之间的电连接件201对显示屏500产生较大的挤压作用力,造成显示屏500出现水波纹,进而保证显示屏500具有较强的显示效果和较长的使用寿命。另外,在天线组件的工作过程中,电连接件201处亦会产生电流,为了保证电连接件201具备较强的导电性能,可以通过在电连接件201上镀金的方式,提升电连接件201的导电能力。另外,在布设电连接件201的过程中,可以使电连接件201设置在靠近框架400的边缘位置,且使电连接件201均靠近天线110的回地位置,更具体地,可以使电连接件201与设置在框架400的外周的天线110的外边缘的距离小于L1,L1具体可以为20mm,进一步提升天线110的整体性能。The
电连接件201设置在电子设备的显示屏500和框架400之间,且使框架400和显示屏500通过电连接件201电性连接,从而利用电连接件201作为天线110的接地点。同时,框架400、显示屏500和电连接件201会形成谐振腔,导致天线110的射频带可能会与谐振腔的固有频率重合,而对天线110的性能产生不利影响。The
基于此,如图2所示,可以通过在天线组件中增设导电结构件10,且使导电结构件10设置在谐振腔中的电场强区的方式,来改变谐振腔的结构,以利用导电结构件10来抑制谐振腔效应,进而改变谐振腔的固有频率,使天线110的射频频带位于谐振腔的固有频率之外,增强天线110的整体性能。Based on this, as shown in FIG. 2 , the structure of the resonant cavity can be changed by adding a conductive
但是,在上述方案中,首先需要增设导电结构件10,并且需要使导电结构件10的电连接性能良好,这可能需要采用为导电结构件10镀金等方式增强导电结构件10的导电性能,一方面会造成电子设备的成本上升,另一方面还会增大电子设备的组装难度,且由于电子设备中相互连接的部件增多,导致电子设备中部件失效的风险增大。However, in the above solution, the conductive
基于此,在本申请实施例中,如图3所示,除了上述天线110和电连接件201之外,天线组件还可以包括吸波结构件300,吸波结构件300为采用吸波材料制成的结构件,且具备吸收电磁波的能力,并且,如图3所示,吸波结构件300设置在谐振腔内,使得谐振腔内的介质发生变化,进而改变谐振腔内的介电性能和磁场分布情况,使得谐振腔的固有频率发生变化,确切地说,吸波结构件300能够降低谐振腔的固有频率,以使天线110的射频频带位于谐振腔的固有频率之外,从而无需在谐振腔中电场强区额外设置需要镀金的导电结构件10,亦可以保证谐振腔不会对天线110的性能产生不利影响,使天线110的整体性能较好。同时,吸波结构件300能够吸收至少一部分杂波,从而降低耦合在电连接件201上的电流,进而降低无源交调带来的风险。Based on this, in the embodiment of the present application, as shown in FIG. 3 , in addition to the above-mentioned
本申请实施例公开一种天线组件,该天线组件可以应用在电子设备中,天线组件中的天线110可以固定连接在电子设备的框架400的外周,且框架400可以通过天线组件中的电连接件201与电子设备的显示屏500形成电性连接关系,且框架400的导电部分、显示屏的导电部分和电连接件201能够形成谐振腔。并且,本申请实施例中的天线组件还包括吸波结构件300,且使吸波结构件300设置在谐振腔内,从而利用吸波结构件300改变谐振腔内的介电常数和/或磁导率,且利用吸波结构件300吸收至少一部分杂波,降低耦合至电连接件201上的电流,进而可以降低无源交调带来的风险;同时,吸波结构件300还可以改变谐振腔的固有频率,使天线110的射频频带位于谐振腔的固有频率之外,保证天线110的接收性能较好。The embodiment of the present application discloses an antenna assembly, which can be applied in an electronic device.

如上所述,在设置吸波结构件300的过程中,吸波结构件300可以为同种材料形成的单层结构件,这种吸波结构件300的介电常数和磁导率为固定值。在这种情况下,可以使吸波结构件300的介电常数和/或磁导率的模值大于10,以保证吸波结构件300对于谐振腔内的介电常数和/或磁导率的改变更为可观,进一步提升吸波结构件300对谐振腔的固有频率的偏移能力,保证谐振腔不会对天线110的性能产生不利影响。As described above, in the process of arranging the wave absorbing
或者,吸波结构件300可以为多种材料层叠形成的多层结构式的吸波结构件300,这种吸波结构件300的介电常数和磁导率可以等效为某一值。在这种情况下,可以使吸波结构件300的等效介电常数和/或等效磁导率的模值大于10,以保证吸波结构件300对于谐振腔内的介电常数和/或磁导率的改变更为可观,进一步提升吸波结构件300对谐振腔的固有频率的偏移能力,保证谐振腔不会对天线110的性能产生不利影响。Alternatively, the wave absorbing
在上述实施例中,无论吸波结构件300为单层结构件还是由多个吸波结构层310形成的多层结构件,吸波结构件300的数量均可以为一个,该吸波结构件300设置在谐振腔内,以使谐振腔的频率发生偏移。并且,通过使该吸波结构件300靠近多个电连接件201中的至少一者,能够使与吸波结构件300之间间距相对较小的电连接件201上的电流相对较小。In the above embodiment, no matter whether the wave absorbing
但是,在吸波结构件300的数量为一个的情况下,吸波结构件300的设置位置总归会受到一定的限制,基于此,在电连接件201的数量为多个的情况下,如图6所示,吸波结构件300的数量可以为多个,且各吸波结构件300均设置在谐振腔内,在组装天线组件的过程中,可以使各个吸波结构件300均设置于多个电连接件201之间,且使任一电连接件201与至少一个吸波结构件300之间的间距均小于20mm。更具体地,可以使某一电连接件201与某一吸波结构件300之间的间距为L3,且使L3为4mm。However, in the case where the number of the wave absorbing
也即,在本实施例中,可以通过增加吸波结构件300的数量,且使吸波结构件300与电连接件201相互配合布置的方式,利用多个吸波结构件300分别降低各自周围的磁场强度,从而使围绕多个吸波结构件300设置的多个电连接件201上的电流均得到减小;并且,在吸波结构件300的数量为多个的情况下,可以使任一吸波结构件300的形状相对规则,从而保证任一吸波结构件300的加工和组装难度均相对较小。That is, in this embodiment, by increasing the number of the wave absorbing
当然,在本申请的另一实施例中,亦可以针对多个电连接件201的具体位置,针对性地设计一个或多个特定形状的吸波结构件300,从而使多个电连接件201与该一个或多个吸波结构件300之间的间距均相对更小。采用这种技术方案,可以进一步保证多个电连接件201上的电流均相对较小,但是,相对而言,这类吸波结构件300的加工难度和组装难度相对较大,并且,这种吸波结构件300的适用局限性相对较大,在本申请的实施过程中,本领域技术人员可以根据实际需求,有针对性地选择不同的技术方案。Of course, in another embodiment of the present application, one or more wave-absorbing

需要说明的是,前述对于谐振腔的面积的定义并非为真正意义上谐振腔的面积,受谐振腔的形成条件的影响,谐振腔的面积的计算方式较为复杂,前述替代方式与谐振腔真正的面积之间可能会存在一定的差异,但是前述差异相较于谐振腔的面积而言数量级相对较小,因而,为了更为直观地表述本技术方案,利用上述计算方式所计算得到的面积作为谐振腔的理论面积。It should be noted that the above-mentioned definition of the area of the resonant cavity is not the area of the resonant cavity in the true sense. Affected by the formation conditions of the resonant cavity, the calculation method of the area of the resonant cavity is more complicated. There may be a certain difference between the areas, but the aforementioned difference is relatively small in magnitude compared to the area of the resonant cavity. Therefore, in order to express the technical solution more intuitively, the area calculated by the above calculation method is used as the resonance cavity. The theoretical area of the cavity.
进而,在实际应用中,可以在条件允许的情况下进一步增大吸波结构件300的面积,以保证吸波结构件300的面积与谐振腔的真实面积的比值大于五分之一,进而保证吸波结构件300具备良好的偏移谐振腔的频率的能力。更具体地,可以使吸波结构件300的面积与谐振腔的面积之间的比值大于二分之一,在这种情况下,吸波结构件300对谐振腔的偏移效果更为可观,能够大幅改善天线110的性能。Furthermore, in practical applications, the area of the wave absorbing
进一步地,可以使吸波结构件300与天线110之间具有间隔,且使吸波结构件300与天线110之间的间距大于10mm,在这种情况下,使得吸波结构件300的组装难度相对较小,且使得多个电连接件201各自的位置的设置范围相对较大,以降低整个天线组件的组装难度。Further, there can be a space between the

结合图9和图10的结果,是否设置导电结构件10对天线组件中Ant A的回波损耗和辐射效率虽然没有影响,但设置导电结构件10会略微降低激励Ant A时耦合到第一电连接件210和第二电连接件220在1850MHz至1990MHz发射频段的电流,电流的具体差值约为20-60mA,因此,如上所述,可以通过设置导电结构件10,以有效降低第一电连接件210和第二电连接件220上的电流,进而有助于实现降低PIM(Passive Inter-Modulatio,无源交调)和RSE(Radiated Spurious Emission,辐射杂散)风险的目的。Combining the results of FIG. 9 and FIG. 10 , whether or not the conductive
进一步地,图13至图16示出了Ant B工作在1850MHz-1990MHz频段的情况。图13和图14是天线组件中是否设置导电结构件10对Ant B的回波损耗曲线和辐射效率曲线对比。其中,圆实线对应图2中天线组件设置有导电结构件10的情况下,Ant B的回波损耗曲线和辐射效率曲线。菱形虚线对应图1中天线组件未设置有导电结构件10的情况下,Ant B的回波损耗曲线和辐射效率曲线。Further, FIG. 13 to FIG. 16 show the case where Ant B works in the frequency band of 1850MHz-1990MHz. FIG. 13 and FIG. 14 are the comparison between the return loss curve and the radiation efficiency curve of Ant B with or without the
基于图示可知,在天线组件未设置导电结构件10的情况下,Ant B在1850MHz附近有一个谐振,实际是由框架400、显示屏500和多个电连接件201构成的谐振腔的固有频率,落在了1850MHz-1990MHz这一发射频段中,且造成了效率损耗。而在天线组件设置有导电结构件10的情况下,上述谐振腔的谐振频率被移到带外,大体上移动到了2200MHz的位置,从而使谐振腔的频率位于非需求频段。并且,在1850MHz附近的工作发射频段,天线110的辐射效率提高了1.2dB。Based on the figure, it can be seen that in the case where the
图15和图16是天线组件中是否设置有导电结构件10对于激励Ant B时,经过第一电连接件210和第二电连接件220的电流值对比。圆实线对应图2中天线组件中设置有导电结构件10的情况下,激励Ant B时经过第一电连接件210和第二电连接件220的电流值曲线。菱形虚线对应图1中天线组件中未设置有导电结构件10的情况下,激励Ant B时经过第一电连接件210和第二电连接件220的电流值曲线。FIGS. 15 and 16 are comparisons of current values passing through the first
结合图13和图14的结果,在天线组件中设置有导电结构件10的情况下,Ant B辐射效率得到提高,且第一电连接件210和第二电连接件220上耦合的电流发生大幅下降。其中,第一电连接件210的电流下降了220mA,第二电连接件220的电流下降了110mA,从而可以大幅降低PIM和RSE风险。而天线组件中未设置导电结构件10的情况下,虽然第一电连接件210与Ant B的距离较大,但受谐振腔效应的影响,第一电连接件210仍然耦合到了极大的电流,电流峰值和谐振腔谐振频率基本对齐,导致天线组件的PIM和RSE风险很高。13 and 14 , in the case where the conductive
综上,为了抑制谐振腔现象,保证天线110效率较高,降低EMC的工作风险,可以采用增加导电结构件10的方式,且由于导电结构件10上的电流相对较大,如图17所示,实线对应激励Ant A的情况,虚线对应激励Ant B的情况,显然,在1850MHz附近导电结构件10的电流大于50Ma,从而需要通过为导电结构件10镀金等方式增强导电结构件10的导电性能,从而大幅增加天线组件的成本,且使得天线组件中部件间的连接关系更为复杂,天线组件的失效风险更高。To sum up, in order to suppress the resonance cavity phenomenon, ensure high efficiency of the
综上,为了保证天线110的性能,且保证天线组件的成本和失效风险仍均相对较低,本申请在天线组件中增设吸波结构件300,吸波结构件300可以使天线110的性能相对较好,且由于吸波结构件300与天线组件中的其他结构件不存在电性连接等较为精密的连接关系,使得天线组件的失效风险相对较低,且吸波结构件300自身的成本亦相对较低,从而不会导致天线组件的整体成本上升过多。To sum up, in order to ensure the performance of the

结合图18和图19的结果,天线组件中是否设置吸波结构件300对于Ant A的回波损耗和辐射效率虽然没有影响,但是在天线组件中设置有吸波结构件300的情况下,能够较大幅度地降低激励Ant A时耦合到第一电连接件210和第二电连接件220在1850MHz-1990MHz发射频段的电流,并且,吸波结构件300的面积越大,以及越靠近对应的电连接件201,该电连接件201的电流降幅越大。如图6所示的双吸波结构件300,在激励Ant A时,第一电连接件210和第二电连接件220在1850MHz附近电流值已经远小于50mA,天线组件的PIM和RSE风险大大降低。18 and FIG. 19 , it can be seen that whether or not the absorbing
图22至图25示出了Ant B工作在1850MHz-1990MHz频段的情况,图22和图23是天线组件中是否设置有吸波结构件300,以及所设置的吸波结构件300的结构形式不同的情况所对应的Ant B的回波损耗曲线和辐射效率曲线对比,并且,图22和图23示出的天线组件中均未设置导电结构件10。其中,三角实线对应图6示出的天线组件设置有双吸波结构件300且靠近第一电连接件210和第二电连接件220的情况下,Ant B的回波损耗曲线和辐射效率曲线。正方形虚线对应图3示出的天线组件设置有单片吸波结构件300,且相较于图6中的吸波结构件300与第一电连接件210和第二电连接件220,图3中的吸波结构件300与第一电连接件210和第二电连接件220相更远的情况下,Ant B的回波损耗曲线和辐射效率曲线。圆点线对应图2示出的天线组件未设置有吸波结构件300的情况下,Ant B的回波损耗曲线和辐射效率曲线,作为对比的基准。Fig. 22 to Fig. 25 show the situation of Ant B working in the frequency band of 1850MHz-1990MHz, Fig. 22 and Fig. 23 are whether the absorbing
基于图22和图23示出的情况可知,对于Ant B来说,吸波结构件300能够有效地抑制在1850MHz附近的谐振腔效应,且可以使天线组件的辐射效率提高0.9dB。Based on the situations shown in FIGS. 22 and 23 , for Ant B, the
综上所述,相比于上述利用导电结构件10抑制谐振腔效应的技术方案,虽然本申请上述增设吸波结构件300的方式对于天线组件的辐射效率的提升差值只有0.3dB,但是,在整体设计上,却可以减少增设一需要镀金的导电结构件10大幅降低了物料成本,而且也不存在因导电结构件10连接稳定性带来的EMC方面的风险。To sum up, compared with the above-mentioned technical solution of using the
图24和图25是是天线组件中是否设置有吸波结构件300,以及所设置的吸波结构件300的结构形式不同的情况下,激励Ant B时经过第一电连接件210和第二电连接件220的电流值对比。其中,三角实线对应图6示出的天线组件设置有双吸波结构件300且靠近第一电连接件210和第二电连接件220的情况下,激励Ant B时经过第一电连接件210和第二电连接件220的电流值对比。正方形虚线对应图3示出的天线组件设置有单片吸波结构件300,且相较于图6中的吸波结构件300与第一电连接件210和第二电连接件220,图3中的吸波结构件300与第一电连接件210和第二电连接件220相更远的情况下,,激励Ant B时经过第一电连接件210和第二电连接件220的电流值对比。圆点线对应图2示出的天线组件未设置有吸波结构件300的情况下,激励Ant B时经过第一电连接件210和第二电连接件220的电流值对比,作为对比的基准。FIG. 24 and FIG. 25 show whether there is a wave absorbing
结合图22和图23的结果,在天线组件中设置有吸波结构件300的情况下,不仅可以提高Ant B的辐射效率,而且可以使第一电连接件210和第二电连接件220上耦合的电流大幅下降。22 and 23, in the case where the wave absorbing
并且,在吸波结构件300为单层结构件,且该吸波结构件300距离第一电连接件210和第二电连接件220距离较远时,可以使第一电连接件210的电流下降190mA左右,使第二电连接件220的电流下降70mA。在吸波结构件300的数量为两个,且两个吸波结构件300分别距离第一电连接件210和第二电连接件220较近时,可以使第一电连接件210的电流下降280mA左右,且使第二电连接件220的电流下降70mA。In addition, when the wave absorbing
其中,对于第一电连接件210而言,激励Ant B时主要通过谐振腔效应,耦合能量到远端的第一电连接件210,吸波结构件300可以有效的抑制谐振腔效应,从而使第一电连接件210电流降幅较大,且吸波结构件300面积越大,越靠近第一电连接件210,对第一电连接件210上的电流的抑制效果越好。由于第一电连接件210上原本的电流相对较大,通常将近330mA,从而必须增加镀金片。而采用本申请实施例提供的技术方案之后,也即,在天线组件中增设吸波结构件300之后,可以使第一电连接件210的电流大幅下降,从而仅需使用常规的具备导电能力的电连接件201即可,而无需再为第一电连接件210增设镀金片或进行镀金操作,从而节省一处镀金片的使用。Among them, for the first
对于第二电连接件220,由于其距离Ant B较近,激励Ant B时耦合到第二电连接件220上的电流,主要可以被拆分为两个部分,一部分是第二电连接件220作为Ant B的射频回流点,有一些电流通过,符合天线110本体的电流模式特征。另一部分是第二电连接件220作为谐振腔的一部分会耦合Ant B的能量,这一部分电流是可以通过吸波结构件300进行抑制,达到降低该部分电流的大小的目的。对于Ant B来说,第二电连接件220主要的作用是作为射频回流点,谐振腔效应产生的电流相较于第一电连接件210的电流低很多,因此面积不同的吸波结构件300对第二电连接件220的电流抑制效果相差不大。但对于激励Ant A的情况,第二电连接件220的电流主要是谐振腔效应耦合产生,在这种情况下,吸波结构件300越靠近第二电连接件220,第二电连接件220的电流降幅就更大。For the second
