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 frame 400 and a display screen 500 , and at least a part of the frame 400 is connected to the display screen 500 . Laminated arrangement, of course, in order to ensure that the display screen 500 and the frame 400 have the ability to be electrically connected to each other, the display screen 500 needs to be provided with a conductive part with electrical conductivity, which can be a metal bracket 530. Correspondingly, the frame 400 also includes The conductive portion with electrical conductivity may be a portion stacked with the display screen 500 , and the outer periphery of the frame 400 may be a metal structure or a structure formed of non-conductive materials such as plastic. In addition, the electronic device may also include components such as a casing, a processor, and a camera module, which are not described here for brevity.

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 antenna 110 and an electrical connector 201 . In the process of assembling the antenna assembly, the antenna 110 can be fixedly connected to the outer periphery of the frame 400, and by electrically connecting the antenna 110 and the conductive part of the frame 400, a good electrical connection can be formed between the antenna 110 and the frame 400 relation. The specific structure and form of the antenna 110 can be determined according to actual requirements, which are not limited here. In addition, the antenna 110 can be integrally formed with the frame 400, and a usable antenna form is formed by etching a groove structure at the outer peripheral edge of the frame 400. This antenna 110 is actually a metal frame antenna, and the frame 400 The connecting rib is equivalent to the grounding part of the antenna 110 . Alternatively, the antenna 110 can also be an FPC antenna. In this case, the outer periphery of the frame 400 can be a plastic structural member, and the antenna 110 can be electrically connected to the conductive part of the frame 400 through a conductive member, so that the antenna 110 can also be The purpose of grounding can be achieved by the frame 400 . For ease of description, a metal frame antenna is used as an example for description below. In addition, as shown in FIG. 1 , the antennas 110 may include multiple antennas of different frequency bands, and the antennas 110 may be separated from each other by slits 120 , and each antenna 110 is provided with a feed point 130 .

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 electrical connector 201 is a device with electrical conductivity, which can be specifically made of materials such as metal, and has various structural forms, which are not limited here. In the specific embodiment of the present application, the electrical connector 201 may be a structure such as a screw or an elastic sheet. In another embodiment of the present application, the electrical connector 201 may be a conductive foam, so as to prevent the electrical connector 201 sandwiched between the frame 400 and the display screen 500 from producing a large pressing force on the display screen 500 , causing water ripples to appear on the display screen 500 , thereby ensuring that the display screen 500 has a strong display effect and a long service life. In addition, during the working process of the antenna assembly, current will also be generated at the electrical connector 201. In order to ensure that the electrical connector 201 has strong electrical conductivity, the electrical connector 201 can be raised by plating gold on the electrical connector 201. conductivity. In addition, in the process of arranging the electrical connectors 201 , the electrical connectors 201 can be arranged near the edge of the frame 400 , and the electrical connectors 201 are all close to the grounding position of the antenna 110 . The distance between the component 201 and the outer edge of the antenna 110 disposed on the outer periphery of the frame 400 is less than L1 , and L1 may be 20 mm, which further improves the overall performance of the antenna 110 .

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 electrical connector 201 is disposed between the display screen 500 and the frame 400 of the electronic device, and the frame 400 and the display screen 500 are electrically connected through the electrical connector 201 , so that the electrical connector 201 is used as the grounding point of the antenna 110 . At the same time, the frame 400 , the display screen 500 and the electrical connector 201 will form a resonant cavity, so that the radio frequency band of the antenna 110 may coincide with the natural frequency of the resonant cavity, thereby adversely affecting the performance of the antenna 110 .

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 structural member 10 in the antenna assembly and setting the conductive structural member 10 in the electric field strong region in the resonant cavity, so as to utilize the conductive structure. The component 10 is used to suppress the effect of the resonant cavity, and then the natural frequency of the resonant cavity is changed, so that the radio frequency band of the antenna 110 is located outside the natural frequency of the resonant cavity, and the overall performance of the antenna 110 is enhanced.

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 structural member 10 needs to be added first, and the electrical connection performance of the conductive structural member 10 needs to be good, which may require the conductive structural member 10 to be plated with gold to enhance the conductive performance. On the one hand, the cost of the electronic device will increase, and on the other hand, the assembly difficulty of the electronic device will be increased, and since the number of interconnected components in the electronic device increases, the risk of failure of the components in the electronic device increases.

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 antenna 110 and the electrical connector 201 , the antenna assembly may further include a wave absorbing structural member 300 , and the wave absorbing structural member 300 is made of a wave absorbing material. and has the ability to absorb electromagnetic waves, and, as shown in FIG. 3 , the wave absorbing structural member 300 is arranged in the resonant cavity, so that the medium in the resonant cavity changes, thereby changing the dielectric properties and properties of the resonant cavity. The distribution of the magnetic field causes the natural frequency of the resonant cavity to change. Specifically, the wave absorbing structure 300 can reduce the natural frequency of the resonant cavity, so that the radio frequency band of the antenna 110 is located outside the natural frequency of the resonant cavity, so that there is no need to resonate The additional conductive structure 10 that needs to be plated with gold is provided in the strong electric field region in the cavity, which can also ensure that the resonant cavity will not adversely affect the performance of the antenna 110 , so that the overall performance of the antenna 110 is better. At the same time, the wave absorbing structural member 300 can absorb at least a part of the clutter, thereby reducing the current coupled to the electrical connecting member 201, thereby reducing the risk of passive intermodulation.

The antenna 110 in the antenna assembly can be fixedly connected to the outer periphery of a frame 400 of the electronic device, and the frame 400 can pass through the electrical connector in the antenna assembly. 201 forms an electrical connection relationship with the display screen 500 of the electronic device, and the conductive portion of the frame 400, the conductive portion of the display screen and the electrical connection member 201 can form a resonant cavity. In addition, the antenna assembly in the embodiment of the present application further includes a wave absorbing structural member 300, and the wave absorbing structural member 300 is arranged in the resonant cavity, so that the dielectric constant and/or magnetic field in the resonant cavity can be changed by using the wave absorbing structural member 300 and absorb at least a part of the clutter by using the absorbing structure 300 to reduce the current coupled to the electrical connector 201, thereby reducing the risk of passive intermodulation; at the same time, the absorbing structure 300 can also change the resonance The natural frequency of the cavity is such that the radio frequency band of the antenna 110 is located outside the natural frequency of the resonant cavity, so as to ensure better reception performance of the antenna 110 .

为了进一步保证天线110具有较好的射频回流效果,且更好地抑制谐振腔杂波,可选地,天线组件中包括多个电连接件201。如上所述,在上述天线组件的工作过程中,电连接件201上仍可能会产生电流,这使得多个电连接件201亦需要具备较强的导电性能,从而使得多个电连接件201亦可能需要采用镀金等方式提升各自的导电性能。基于此,在本实施例中,如图3所示,可以使多个电连接件201中的至少一者与吸波结构件300之间的间距小于L2,L2具体可以取20mm。In order to further ensure that the antenna 110 has a better effect of RF backflow and better suppress the clutter of the resonant cavity, optionally, the antenna assembly includes a plurality of electrical connectors 201 . As mentioned above, during the working process of the above-mentioned antenna assembly, current may still be generated on the electrical connectors 201 , which makes the plurality of electrical connectors 201 also need to have strong electrical conductivity, so that the plurality of electrical connectors 201 also have strong electrical conductivity. It may be necessary to improve the respective conductivity by means of gold plating, etc. Based on this, in this embodiment, as shown in FIG. 3 , the distance between at least one of the plurality of electrical connectors 201 and the wave absorbing structure 300 may be smaller than L2 , which may specifically be 20 mm.

在采用上述技术方案的情况下,可以利用吸波结构件300改变其自身周围的磁场,具体来说,可以减小吸波结构件300周围的磁场,基于磁场环路积分理论,使得吸波结构件300周围的电场强度降低,从而使临近于吸波结构件300上的电流进一步减小,基于此,通过使多个电连接件201中的至少一者与吸波结构件300之间距离相对较小,具体可以使电连接件201与吸波结构件300之间的间距小于20mm的方式,利用吸波结构件300进一步减小该电连接件201上的电流大小,从而使得该电连接件201对于导电能力的需求下限降低,进而可以使该电连接件201无需再采用镀金的方式提升其导电能力,达到降低成本和减小加工和组装难度的作用。In the case of adopting the above technical solution, the wave absorbing structure 300 can be used to change the magnetic field around itself, specifically, the magnetic field around the wave absorbing structure 300 can be reduced. Based on the magnetic field loop integral theory, the wave absorbing structure can be The electric field strength around the component 300 is reduced, so that the current adjacent to the wave absorbing structure 300 is further reduced. Based on this, the distance between at least one of the plurality of electrical connecting components 201 and the wave absorbing structure 300 is opposite. Specifically, the distance between the electrical connector 201 and the wave absorbing structural member 300 can be made smaller than 20 mm, and the wave absorbing structural member 300 can be used to further reduce the current on the electrical connecting member 201, so that the electrical connecting member The lower limit of the requirement for the electrical conductivity of the electrical connector 201 is reduced, so that the electrical connector 201 does not need to be gold-plated to improve its electrical conductivity, thereby reducing the cost and the difficulty of processing and assembling.

另外,考虑到部件的装配过程,可以使任一电连接件201均与吸波结构件300相互间隔,也即,使任一电连接件201均与吸波结构件300之间具有大于零的间隙,从而是部件间存在组装公差,降低部件的组装难度。更具体地,任一电连接件201与吸波结构件300之间的间距均可以大于3mm。In addition, considering the assembly process of the components, any electrical connector 201 can be spaced from the wave absorbing structural member 300, that is, any electrical connecting member 201 and the wave absorbing structural member 300 have a distance greater than zero between them. There is a gap between the components, so there is an assembly tolerance between the components, which reduces the assembly difficulty of the components. More specifically, the distance between any electrical connection member 201 and the wave absorbing structural member 300 may be greater than 3 mm.

进一步地,吸波结构件300的具体形状可以根据实际需求选定,此处不作限定,例如,吸波结构件300可以为三角形、圆形、椭圆形或多边形等。并且,吸波结构件300可以为闭合环状结构件,还可以为具有开口的环状结构件。在本申请的一个具体实施例中,吸波结构件300可以为矩形结构件,这可以降低吸波结构件300的加工难度,且可以提升吸波结构件300的适应性,扩大其应用场景。Further, the specific shape of the wave absorbing structural member 300 can be selected according to actual requirements, which is not limited here. For example, the wave absorbing structural member 300 can be a triangle, a circle, an ellipse, or a polygon. Moreover, the wave absorbing structural member 300 may be a closed annular structural member, and may also be an annular structural member having an opening. In a specific embodiment of the present application, the wave absorbing structural member 300 can be a rectangular structural member, which can reduce the processing difficulty of the wave absorbing structural member 300, and can improve the adaptability of the wave absorbing structural member 300 and expand its application scenarios.

可选地,如图4所示,吸波结构件300可以为单层结构件,也即,吸波结构件300为采用同种材料形成的一体式结构件,这种吸波结构件300的加工难度和组装难度均相对较低。Optionally, as shown in FIG. 4 , the wave absorbing structural member 300 may be a single-layer structural member, that is, the wave absorbing structural member 300 is an integrated structural member formed of the same material. The processing difficulty and assembly difficulty are relatively low.

在本申请的另一实施例中,如图5所示,吸波结构件300可以包括多个吸波结构层310,多个吸波结构层310沿显示屏500和框架400的层叠方向层叠设置,并且,各吸波结构层310的电参数均相异。其中,显示屏500和框架400的层叠方向也可以被认为是天线110的厚度方向,即图4中的方向Y。并且,在本实施例中,各吸波结构层310的电参数均相异,在采用这种技术方案的情况下,各吸波结构层310的材质可以分别选择,扩大了吸波结构层310的选型范围,从而可以根据实际需求灵活地选定各吸波结构层310各自的介电常数和/或磁导率,以及各吸波结构层310的尺寸等,从而利用多个吸波结构层310形成的吸波结构件300这一整体结构件为谐振腔的频率提供偏移作用,提升天线110的性能。In another embodiment of the present application, as shown in FIG. 5 , the wave absorbing structure member 300 may include a plurality of wave absorbing structure layers 310 , and the plurality of wave absorbing structure layers 310 are stacked along the stacking direction of the display screen 500 and the frame 400 . , and the electrical parameters of each wave absorbing structure layer 310 are different. The stacking direction of the display screen 500 and the frame 400 may also be regarded as the thickness direction of the antenna 110 , that is, the direction Y in FIG. 4 . In addition, in this embodiment, the electrical parameters of each wave absorbing structure layer 310 are different. In the case of adopting this technical solution, the material of each wave absorbing structure layer 310 can be selected separately, which enlarges the wave absorbing structure layer 310 Therefore, the dielectric constant and/or magnetic permeability of each wave-absorbing structure layer 310 and the size of each wave-absorbing structure layer 310 can be flexibly selected according to actual needs, so as to utilize multiple wave-absorbing structures The overall structure of the wave absorbing structure 300 formed by the layer 310 provides a shift effect for the frequency of the resonant cavity, thereby improving the performance of the antenna 110 .

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 structural member 300, the wave absorbing structural member 300 may be a single-layer structural member formed of the same material, and the dielectric constant and magnetic permeability of the wave absorbing structural member 300 are fixed values . In this case, the mode value of the dielectric constant and/or the magnetic permeability of the wave absorbing structure 300 can be set to be greater than 10, so as to ensure the dielectric constant and/or the magnetic permeability of the wave absorbing structure 300 in the resonant cavity. The change is more considerable, further improving the ability of the wave absorbing structure 300 to shift the natural frequency of the resonant cavity, and ensuring that the resonant cavity will not adversely affect the performance of the antenna 110 .

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 structural member 300 may be a multi-layered structural wave absorbing structural member 300 formed by stacking multiple materials, and the dielectric constant and magnetic permeability of the wave absorbing structural member 300 may be equivalent to a certain value. In this case, the mode value of the equivalent permittivity and/or the equivalent permeability of the wave absorbing structure 300 can be set to be greater than 10, so as to ensure that the wave absorbing structure 300 has no effect on the permittivity and/or the equivalent magnetic permeability in the resonant cavity. Or the change of the magnetic permeability is more considerable, which further improves the ability of the wave absorbing structure 300 to shift the natural frequency of the resonant cavity, and ensures that the resonant cavity does not adversely affect the performance of the antenna 110 .

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 structural member 300 is a single-layer structural member or a multi-layer structural member formed by a plurality of wave absorbing structural layers 310 , the number of the wave absorbing structural member 300 can be one. 300 is arranged in the resonant cavity to shift the frequency of the resonant cavity. In addition, by placing the wave absorbing structural member 300 close to at least one of the plurality of electrical connecting members 201 , the current on the electrical connecting member 201 with a relatively small distance from the wave absorbing structural member 300 can be made relatively small.

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 structural member 300 is one, the installation position of the wave absorbing structural member 300 will always be limited to a certain extent. Based on this, in the case where the number of the electrical connecting members 201 is multiple, as shown in FIG. As shown in Fig. 6, the number of the wave absorbing structural members 300 can be multiple, and each wave absorbing structural member 300 is arranged in the resonant cavity. In the process of assembling the antenna assembly, each wave absorbing structural member 300 can be arranged in multiple Between each of the electrical connectors 201, and the distance between any electrical connector 201 and the at least one wave absorbing structure 300 is less than 20 mm. More specifically, the distance between a certain electrical connection member 201 and a certain wave absorbing structural member 300 may be L3, and L3 may be 4 mm.

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 structural members 300 and arranging the wave absorbing structural members 300 and the electrical connecting member 201 to cooperate with each other, the plurality of wave absorbing structural members 300 can be used to reduce the surrounding area respectively Therefore, the currents on the plurality of electrical connectors 201 arranged around the plurality of wave absorbing structural members 300 are reduced; and, in the case that the number of the wave absorbing structural members 300 is multiple, any The shape of a wave absorbing structure 300 is relatively regular, so as to ensure that the processing and assembly difficulty of any wave absorbing structure 300 is relatively small.

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 structural members 300 with a specific shape can also be specifically designed for the specific positions of the plurality of electrical connectors 201 , so that the plurality of electrical connectors 201 The distance from the one or more wave absorbing structural members 300 is relatively smaller. With this technical solution, the currents on the plurality of electrical connectors 201 can be further guaranteed to be relatively small. However, relatively speaking, the processing difficulty and assembly difficulty of this type of wave absorbing structure 300 are relatively high, and this kind of wave absorbing structure is relatively difficult to assemble. The applicable limitations of the wave absorbing structural member 300 are relatively large. During the implementation of the present application, those skilled in the art can select different technical solutions in a targeted manner according to actual needs.

为了进一步确保吸波结构件300具备较好的偏移谐振腔频率的能力,进一步地,可以使吸波结构件300在框架400和显示屏500的层叠方向上的投影的面积与谐振腔在前述层叠方向上的投影的面积的比值大于五分之一。其中,吸波结构件300通常可以为规则的柱状结构件,进而吸波结构件300的顶面或底面,也即,图3中吸波结构件300展示的面的面积即为吸波结构件300在层叠方向上的投影的面积。谐振腔的在前述层叠方向上的投影的面积亦可以被简化为多个电连接件201之间的连线围成图形的面积。In order to further ensure that the wave absorbing structural member 300 has a better ability to shift the frequency of the resonant cavity, further, the projected area of the wave absorbing structural member 300 in the stacking direction of the frame 400 and the display screen 500 can be the same as the resonant cavity in the aforementioned The ratio of the projected areas in the stacking direction is greater than one fifth. Wherein, the wave absorbing structural member 300 can generally be a regular columnar structural member, and then the top surface or the bottom surface of the wave absorbing structural member 300, that is, the area of the surface shown by the wave absorbing structural member 300 in FIG. 3 is the wave absorbing structural member 300 The projected area in the stacking direction. The projected area of the resonant cavity in the aforementioned stacking direction can also be simplified as the area of the pattern formed by the connecting lines between the plurality of electrical connectors 201 .

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 structural member 300 can be further increased if conditions permit, to ensure that the ratio of the area of the wave absorbing structural member 300 to the real area of the resonant cavity is greater than one-fifth, thereby ensuring that The wave absorbing structure 300 has a good ability to shift the frequency of the resonant cavity. More specifically, the ratio between the area of the wave absorbing structural member 300 and the area of the resonant cavity can be made greater than one-half. The performance of the antenna 110 can be greatly improved.

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 wave absorbing structure 300 and the antenna 110 , and the distance between the wave absorbing structure 300 and the antenna 110 can be set to be greater than 10 mm. In this case, it is difficult to assemble the wave absorbing structure 300 It is relatively small, and the setting range of the respective positions of the plurality of electrical connectors 201 is relatively large, so as to reduce the assembly difficulty of the entire antenna assembly.

进一步地,本申请实施例公开的天线组件中,天线110包括GPS天线、WIFI天线、2G天线、3G天线、4G天线、5G天线和毫米波天线中的至少一者。更具体地,天线110可以包括上述不同类型的天线110中的任一者,从而扩大天线110的射频频段,提升天线110的适用范围。Further, in the antenna assembly disclosed in the embodiments of the present application, the antenna 110 includes at least one of a GPS antenna, a WIFI antenna, a 2G antenna, a 3G antenna, a 4G antenna, a 5G antenna, and a millimeter-wave antenna. More specifically, the antenna 110 may include any one of the above-mentioned different types of antennas 110 , thereby expanding the radio frequency band of the antenna 110 and increasing the applicable range of the antenna 110 .

如图1至图3所示,天线110中均可以包括Ant(antenna,天线)A和Ant B,Ant A和Ant B分别位于天线110的相背两端,其中,Ant A位于谐振腔的腔底所在一侧,Ant B位于谐振腔的腔口所在一侧,Ant A和Ant B均可以工作在1850MHz至1990MHz频段。并且,天线组件中的多个电连接件201可以包括第一电连接件210和第二电连接件220,第一电连接件210位于谐振腔的腔底所在处,第二电连接件220设置在谐振腔的腔口所在处。另外,如上所述,导电结构件10和各电连接件201均可以为导电泡棉,进而,导电结构件10、第一电连接件210和第二电连接件220可以分别被称为泡棉a、泡棉b和泡棉c。As shown in FIG. 1 to FIG. 3 , the antenna 110 may include Ant (antenna) A and Ant B. Ant A and Ant B are respectively located at opposite ends of the antenna 110 , wherein Ant A is located in the cavity of the resonant cavity. On the side where the bottom is located, Ant B is located on the side where the cavity mouth of the resonator is located, and both Ant A and Ant B can work in the frequency band of 1850MHz to 1990MHz. In addition, the plurality of electrical connectors 201 in the antenna assembly may include a first electrical connector 210 and a second electrical connector 220, the first electrical connector 210 is located at the bottom of the resonant cavity, and the second electrical connector 220 is provided at the mouth of the resonant cavity. In addition, as described above, the conductive structural member 10 and each electrical connection member 201 may be conductive foam, and further, the conductive structural member 10, the first electrical connection member 210 and the second electrical connection member 220 may be referred to as foam, respectively a, foam b and foam c.

图9和图10是天线组件中是否设置有导电结构件10对Ant A的回波损耗曲线和辐射效率曲线对比。其中,三角实线对应图2示出的天线组件设置有导电结构件10的情况下,Ant A的回波损耗曲线和辐射效率曲线。圆虚线对应图1中天线组件未设置有导电结构件10的情况下,Ant A的回波损耗曲线和辐射效率曲线。如图可知,是否在天线组件中设置导电结构件10,对于天线110Ant A的回波损耗和辐射效率几乎无影响。FIG. 9 and FIG. 10 are the comparison between the return loss curve and the radiation efficiency curve of Ant A with or without the conductive structural member 10 in the antenna assembly. The solid triangle line corresponds to the return loss curve and radiation efficiency curve of Ant A when the antenna assembly shown in FIG. 2 is provided with the conductive structural member 10 . The dotted circle line corresponds to the return loss curve and radiation efficiency curve of Ant A when the antenna assembly in FIG. 1 is not provided with the conductive structural member 10 . As can be seen from the figure, whether or not the conductive structural member 10 is provided in the antenna assembly has little effect on the return loss and radiation efficiency of the antenna 110Ant A.

图11和图12是天线组件中是否设置有导电结构件10对激励Ant A时,第一电连接件210和第二电连接件220上的电流值对比。其中,三角实线对应天线组件中设有导电结构件10的情况下,激励Ant A时,第一电连接件210和第二电连接件220上的电流值曲线。圆虚线对应天线组件中未设有导电结构件10的情况下,激励Ant A时第一电连接件210和第二电连接件220上的电流值曲线。11 and 12 are comparisons of current values on the first electrical connector 210 and the second electrical connector 220 when the antenna assembly is provided with the conductive structure 10 to excite Ant A. The solid triangle line corresponds to the current value curve on the first electrical connector 210 and the second electrical connector 220 when the antenna assembly is provided with the conductive structure 10 when Ant A is excited. The dotted circle line corresponds to the current value curve on the first electrical connector 210 and the second electrical connector 220 when the antenna assembly is not provided with the conductive structure 10 when Ant A is excited.

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 structural member 10 is provided has no effect on the return loss and radiation efficiency of Ant A in the antenna assembly, but the provision of the conductive structural member 10 will slightly reduce the coupling to the first electric current when Ant A is excited. The current of the connecting member 210 and the second electrical connecting member 220 in the emission frequency band of 1850MHz to 1990MHz, the specific difference of the current is about 20-60mA. Therefore, as described above, the conductive structural member 10 can be provided to effectively reduce the first electrical current. The currents on the connection member 210 and the second electrical connection member 220 further help to achieve the purpose of reducing the risk of PIM (Passive Inter-Modulatio, passive intermodulation) and RSE (Radiated Spurious Emission, radiation spurious).

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 conductive structure 10 in the antenna assembly. Wherein, the solid circle line corresponds to the return loss curve and radiation efficiency curve of Ant B when the antenna assembly is provided with the conductive structural member 10 in FIG. 2 . The dashed diamond line corresponds to the return loss curve and radiation efficiency curve of Ant B when the antenna assembly in FIG. 1 is not provided with the conductive structural member 10 .

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 conductive structure 10 is not provided in the antenna assembly, Ant B has a resonance near 1850 MHz, which is actually the natural frequency of the resonant cavity formed by the frame 400 , the display screen 500 and the plurality of electrical connectors 201 . , falls in the transmission frequency band of 1850MHz-1990MHz, and causes efficiency loss. In the case where the antenna assembly is provided with the conductive structural member 10, the resonant frequency of the resonant cavity is moved out of band, generally to a position of 2200 MHz, so that the frequency of the resonant cavity is located in an undesired frequency band. Moreover, in the working emission frequency band around 1850MHz, the radiation efficiency of the antenna 110 is improved by 1.2dB.

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 electrical connector 210 and the second electrical connector 220 when the antenna assembly is provided with or without the conductive structure 10 to excite Ant B. The solid circle line corresponds to the curve of the current value passing through the first electrical connector 210 and the second electrical connector 220 when the antenna assembly 10 is provided in FIG. 2 when the Ant B is excited. The dashed diamond line corresponds to the curve of the current value passing through the first electrical connector 210 and the second electrical connector 220 when the Ant B is excited when the conductive structure 10 is not provided in the antenna assembly in FIG. 1 .

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 structural member 10 is provided in the antenna assembly, the Ant B radiation efficiency is improved, and the current coupled to the first electrical connection member 210 and the second electrical connection member 220 is greatly increased. decline. The current of the first electrical connector 210 is reduced by 220 mA, and the current of the second electrical connector 220 is decreased by 110 mA, thereby greatly reducing the risk of PIM and RSE. In the case where the conductive structural member 10 is not provided in the antenna assembly, although the distance between the first electrical connection member 210 and Ant B is relatively large, due to the effect of the resonant cavity, the first electrical connection member 210 is still coupled to a great current , the current peak and the cavity resonant frequency are substantially aligned, resulting in a high risk of PIM and RSE for the antenna assembly.

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 antenna 110, and reduce the working risk of EMC, the method of increasing the conductive structure 10 can be adopted, and since the current on the conductive structure 10 is relatively large, as shown in FIG. 17 , the solid line corresponds to the excitation of Ant A, and the dashed line corresponds to the excitation of Ant B. Obviously, the current of the conductive structure 10 is greater than 50Ma near 1850MHz, so it is necessary to enhance the conduction of the conductive structure 10 by plating the conductive structure 10 with gold or other means. Therefore, the cost of the antenna assembly is greatly increased, the connection relationship between the components in the antenna assembly is more complicated, and the failure risk of the antenna assembly is higher.

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 antenna 110, and to ensure that the cost and failure risk of the antenna assembly are still relatively low, the present application adds a wave absorbing structural member 300 to the antenna assembly, and the wave absorbing structural member 300 can make the performance of the antenna 110 relatively low. It is better, and because the wave absorbing structural member 300 does not have a relatively precise connection relationship such as electrical connection with other structural members in the antenna assembly, the failure risk of the antenna assembly is relatively low, and the cost of the wave absorbing structural member 300 itself is also low. Relatively low, so that the overall cost of the antenna assembly does not rise too much.

图18至图21示出了天线110Ant A工作在1850MHz-1990MHz频段的情况,其中,图18和图19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 A的回波损耗曲线和辐射效率曲线对比,并且,图18和图19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中双吸波结构件300且靠近第一电连接件210和第二电连接件220的情况下,Ant A的回波损耗曲线和辐射效率曲线。正方形虚线对应图3中单个吸波结构件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 A的回波损耗曲线和辐射效率曲线。圆点线对应图2示出的天线组件中未设置吸波结构件300的情况下,Ant A的回波损耗曲线和辐射效率曲线,作为对比的基准。显然,基于图18和图19可知,对于Ant A而言,天线组件中是否设置吸波结构件300对其回波损耗和辐射效率几乎无影响。FIGS. 18 to 21 show the situation that the antenna 110Ant A operates in the frequency band of 1850MHz-1990MHz, wherein FIGS. 18 and 19 are whether the wave absorbing structural member 300 is provided in the antenna assembly, and whether the wave absorbing structural member 300 is provided. The return loss curve and radiation efficiency curve of Ant A corresponding to different structural forms are compared, and the conductive structural member 10 is not provided in the antenna assemblies shown in FIG. 18 and FIG. 19 . The solid triangle line corresponds to the return loss curve and radiation efficiency curve of Ant A when the double wave absorbing structure 300 in FIG. 6 is close to the first electrical connector 210 and the second electrical connector 220 . The dashed square line corresponds to the single wave absorbing structure 300 in FIG. 3 , and compared with the wave absorbing structure 300 and the first electrical connecting member 210 and the second electrical connecting member 220 in FIG. 6 , the wave absorbing structural member 300 in FIG. 3 Return loss curve and radiation efficiency curve of Ant A at a farther distance from the first electrical connector 210 and the second electrical connector 220 . The dotted line corresponds to the return loss curve and the radiation efficiency curve of Ant A in the case where the wave absorbing structural member 300 is not provided in the antenna assembly shown in FIG. 2 , as a reference for comparison. Obviously, based on FIG. 18 and FIG. 19 , for Ant A, whether or not the wave absorbing structure 300 is provided in the antenna assembly has little effect on its return loss and radiation efficiency.

图20和图21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,对应于激励Ant A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中双吸波结构件300且靠近第一电连接件210和第二电连接件220的情况下,Ant A激励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中单个吸波结构件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 A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中天线组件中未设置有吸波结构件300的情况下,激励Ant A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. 20 and FIG. 21 show whether the wave absorbing structural member 300 is provided in the antenna assembly, and the structure of the set wave absorbing structural member 300 is different, which corresponds to the first electrical connecting member 210 and the second electrical connecting member 210 when the Ant A is excited. The current value of the electrical connector 220 is compared. Wherein, the solid triangle line corresponds to the case where the double wave absorbing structure 300 in FIG. 6 is close to the first electrical connector 210 and the second electrical connector 220 , Ant A passes through the first electrical connector 210 and the second electrical connection when excited. The current value of the device 220 is compared. The dashed square line corresponds to the single wave absorbing structure 300 in FIG. 3 , and compared with the wave absorbing structure 300 and the first electrical connecting member 210 and the second electrical connecting member 220 in FIG. 6 , the wave absorbing structural member 300 in FIG. 3 Compared with the case where the first electrical connector 210 and the second electrical connector 220 are farther away, the current values passing through the first electrical connector 210 and the second electrical connector 220 when Ant A is excited are compared. The dotted line corresponds to the comparison of current values passing through the first electrical connector 210 and the second electrical connector 220 when Ant A is excited when the antenna assembly in FIG.

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 structure 300 is provided in the antenna assembly has no effect on the return loss and radiation efficiency of Ant A, but in the case where the absorbing structure 300 is provided in the antenna assembly, it can be The current coupled to the first electrical connector 210 and the second electrical connector 220 in the emission frequency band of 1850MHz-1990MHz is greatly reduced when Ant A is excited, and the larger the area of the wave absorbing structure 300, the closer to the corresponding For the electrical connector 201, the greater the current drop of the electrical connector 201 is. As shown in FIG. 6 , when Ant A is excited, the current value of the first electrical connector 210 and the second electrical connector 220 is much less than 50 mA near 1850 MHz, and the PIM and RSE risks of the antenna assembly are great. reduce.

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 structure 300 is provided in the antenna assembly, and the structure of the absorbing structure 300 is different The return loss curve and radiation efficiency curve of Ant B corresponding to the case of , are compared, and the conductive structural member 10 is not provided in the antenna assembly shown in FIG. 22 and FIG. 23 . The solid triangle line corresponds to the return loss curve and radiation efficiency of Ant B when the antenna assembly shown in FIG. curve. The square dotted line corresponds to the antenna assembly shown in FIG. 3 is provided with a single-piece wave absorbing structure 300 , and compared with the wave absorbing structure 300 and the first electrical connector 210 and the second electrical connector 220 in FIG. 6 , FIG. 3 The return loss curve and radiation efficiency curve of Ant B in the case where the wave absorbing structural member 300 is farther away from the first electrical connection member 210 and the second electrical connection member 220 . The dotted line corresponds to the return loss curve and the radiation efficiency curve of Ant B in the case where the antenna assembly shown in FIG. 2 is not provided with the wave absorbing structural member 300 , as a reference for comparison.

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 wave absorbing structure 300 can effectively suppress the cavity effect near 1850 MHz, and can increase the radiation efficiency of the antenna assembly by 0.9 dB.

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 conductive structure 10 to suppress the effect of the resonant cavity, although the method of adding the wave absorbing structure 300 in the present application can only improve the radiation efficiency of the antenna assembly by 0.3dB, however, In the overall design, it is possible to reduce the addition of a conductive structure 10 requiring gold plating, which greatly reduces the material cost, and there is no risk of EMC due to the connection stability of the conductive structure 10 .

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 structural member 300 in the antenna assembly, and when the structure of the wave absorbing structural member 300 is different, when Ant B is excited, it passes through the first electrical connection member 210 and the second electrical connection member 210. The current value of the electrical connector 220 is compared. Wherein, the solid triangle line corresponds to the case where the antenna assembly shown in FIG. 6 is provided with double wave absorbing structural members 300 and is close to the first electrical connector 210 and the second electrical connector 220 , and when Ant B is excited, it passes through the first electrical connector The current values of 210 and the second electrical connector 220 are compared. The square dotted line corresponds to the antenna assembly shown in FIG. 3 is provided with a single-piece wave absorbing structure 300 , and compared with the wave absorbing structure 300 and the first electrical connector 210 and the second electrical connector 220 in FIG. 6 , FIG. 3 In the case where the wave absorbing structure 300 is farther away from the first electrical connector 210 and the second electrical connector 220, the current value passing through the first electrical connector 210 and the second electrical connector 220 when the Ant B is excited Compared. The dotted line corresponds to the comparison of the current values passing through the first electrical connector 210 and the second electrical connector 220 when the antenna assembly shown in FIG. 2 is not provided with the wave absorbing structural member 300 when the Ant B is excited, as a reference for comparison .

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 structural member 300 is provided in the antenna assembly, not only the radiation efficiency of Ant B can be improved, but also the first electrical connection member 210 and the second electrical connection member 220 can be The coupled current drops significantly.

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 structural member 300 is a single-layer structural member, and the wave absorbing structural member 300 is far away from the first electrical connecting member 210 and the second electrical connecting member 220 , the current of the first electrical connecting member 210 can be reduced. The current of the second electrical connection member 220 is reduced by about 190 mA by 70 mA. When the number of wave absorbing structural members 300 is two and the two wave absorbing structural members 300 are respectively close to the first electrical connecting member 210 and the second electrical connecting member 220 , the current of the first electrical connecting member 210 can be reduced 280mA, and the current of the second electrical connector 220 is reduced by 70mA.

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 electrical connector 210, when the Ant B is excited, the resonant cavity effect is mainly used to couple the energy to the first electrical connector 210 at the far end, and the wave absorbing structure 300 can effectively suppress the resonant cavity effect, so that the The current of the first electrical connection member 210 has a larger drop, and the larger the area of the wave absorbing structural member 300 is, the closer it is to the first electrical connection member 210 , the better the current suppression effect on the first electrical connection member 210 is. Since the original current on the first electrical connector 210 is relatively large, usually close to 330 mA, a gold-plated sheet must be added. However, after adopting the technical solutions provided by the embodiments of the present application, that is, after adding the wave absorbing structural member 300 to the antenna assembly, the current of the first electrical connection member 210 can be greatly reduced, so that only a conventional electrical connection member 210 needs to be used. The electrical connector 201 is sufficient, and there is no need to add a gold-plated sheet or perform a gold-plating operation for the first electrical connector 210 , thereby saving the use of one gold-plated sheet.

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 electrical connector 220, since it is relatively close to Ant B, the current coupled to the second electrical connector 220 when Ant B is excited can be divided into two parts, one of which is the second electrical connector 220 As the RF return point of Ant B, some current flows through, which conforms to the current mode characteristics of the antenna 110 body. The other part is that the second electrical connector 220, as a part of the resonant cavity, will couple the energy of Ant B, and this part of the current can be suppressed by the wave absorbing structure 300, so as to reduce the size of this part of the current. For Ant B, the main function of the second electrical connector 220 is to serve as the RF reflow point, and the current generated by the resonant cavity effect is much lower than the current of the first electrical connector 210 , so the absorbing structures 300 with different areas are The current suppression effect on the second electrical connection member 220 is not much different. But for the case of exciting Ant A, the current of the second electrical connector 220 is mainly generated by the resonator effect coupling. In this case, the closer the wave absorbing structure 300 is to the second electrical connector 220, the more The current drops even more.

基于上述任一实施例,本申请还公开一种电子设备,电子设备包括显示屏500、框架400和上述任一实施例公开的天线组件,当然,电子设备还可以包括壳体、处理器和摄像模组等其他器件,考虑文本简洁,此处不再详细介绍。Based on any of the above embodiments, the present application further discloses an electronic device, the electronic device includes a display screen 500, a frame 400 and the antenna assembly disclosed in any of the above embodiments, of course, the electronic device may also include a casing, a processor and a camera Modules and other devices, considering the brevity of the text, will not be described in detail here.

其中,天线组件中的天线110连接在框架400的外周,天线110与框架400的导电部分电性连接,天线组件中的电连接件201位于框架400和显示屏500之间,且显示屏500与框架400通过电连接件201电性连接,从而使天线110通过电连接件201接地。The antenna 110 in the antenna assembly is connected to the outer circumference of the frame 400, the antenna 110 is electrically connected to the conductive part of the frame 400, the electrical connector 201 in the antenna assembly is located between the frame 400 and the display screen 500, and the display screen 500 is connected to the conductive part of the frame 400. The frame 400 is electrically connected through the electrical connector 201 , so that the antenna 110 is grounded through the electrical connector 201 .

更具体地,如图8所示,显示屏500可以包括触控面板510、触控模组520和金属支架530,触控模组520可以包括基板玻璃、偏光片、控制电极和液晶等部分。触控面板510设置在触控模组520的一侧,金属支架530设置在触控模组520的另一侧,金属支架530可以采用铜箔或不锈钢等材料制成,利用金属支架530可以降低整个显示屏500和天线组件之间的相互干扰,且可以降低对天线组件的效率的损耗。在连接显示屏500和框架400的过程中,电连接件201具体连接在框架400和显示屏500的金属支架530之间。More specifically, as shown in FIG. 8 , the display screen 500 may include a touch panel 510 , a touch module 520 and a metal bracket 530 , and the touch module 520 may include a substrate glass, a polarizer, a control electrode and a liquid crystal. The touch panel 510 is arranged on one side of the touch module 520, and the metal bracket 530 is arranged on the other side of the touch module 520. The metal bracket 530 can be made of copper foil or stainless steel. Mutual interference between the entire display screen 500 and the antenna assembly can reduce the loss of efficiency of the antenna assembly. In the process of connecting the display screen 500 and the frame 400 , the electrical connector 201 is specifically connected between the frame 400 and the metal bracket 530 of the display screen 500 .

更具体地,在设计吸波结构件300的过程中,可以使吸波结构件300的厚度等于金属支架530和框架400之间的间距。在本申请的另一实施例中,可以使吸波结构件300安装在框架400上,且使吸波结构件300与显示屏500间隔设置,也即,吸波结构件300的厚度小于框架400和与金属支架530之间的间距,从而使吸波结构件300与金属支架530相互间隔,进而降低天线组件的组装难度,防止因部件的公差或组装误差等因素造成吸波结构件300挤压显示屏500,保证显示屏500的显示效果较好,且保证显示屏500的使用寿命相对较高。More specifically, in the process of designing the wave absorbing structural member 300 , the thickness of the wave absorbing structural member 300 can be made equal to the distance between the metal bracket 530 and the frame 400 . In another embodiment of the present application, the wave absorbing structural member 300 can be installed on the frame 400 , and the wave absorbing structural member 300 and the display screen 500 can be arranged at intervals, that is, the thickness of the wave absorbing structural member 300 is smaller than that of the frame 400 and the distance between the absorbing structure 300 and the metal support 530, thereby reducing the difficulty of assembling the antenna assembly and preventing the absorbing structure 300 from being squeezed due to component tolerances or assembly errors. The display screen 500 ensures that the display effect of the display screen 500 is good, and the service life of the display screen 500 is relatively high.
