技术领域Technical field
本公开涉及无线通信技术领域，尤其涉及一种天线模组及电子设备。The present disclosure relates to the field of wireless communication technology, and in particular to an antenna module and electronic equipment.
背景技术Background technique
随着电子技术的飞速发展，智能手机以及平板电脑等电子设备已越来越普及，并逐渐成为人们日常生活不可缺少的工具。人们在使用电子设备过程中，对于电子设备的要求也越来高，尤其是电子设备的通信性能，因此多输入多输出(Multiple-Input Multiple-Output，MIMO)技术被广泛应用于电子设备中，通过电子设备设置多个天线产生多个谐振模态，以提升电子设备在不同频段上的信号收发性能。With the rapid development of electronic technology, electronic devices such as smart phones and tablet computers have become more and more popular, and have gradually become indispensable tools in people's daily life. In the process of using electronic equipment, people have higher and higher requirements for electronic equipment, especially the communication performance of electronic equipment. Therefore, Multiple-Input Multiple-Output (MIMO) technology is widely used in electronic equipment. Multiple antennas are provided by the electronic device to generate multiple resonance modes, so as to improve the signal transmission and reception performance of the electronic device on different frequency bands.
在MIMO技术中，为满足不断增加的电子设备的数据的需求量，要求电子设备的天线模组产生的谐振模态也越来越多。其中，相关技术中的天线模组通常是在金属体上开设断口，以使断口两侧的金属臂形成天线辐射体，且每一天线辐射体提供覆盖一个频段的谐振模态。这样，当要求天线模组产生较多的谐振模态时，会导致天线模组中开设的断口过多，而断口过多将会引起天线模组的天线模组的通信性能降低。例如，断口过多时可能会导致两个断口之间的距离变小，从而使得形成的天线辐射体之间的隔离度变差，等等。In MIMO technology, in order to meet the ever-increasing data demand of electronic devices, more and more resonance modes are required to be generated by antenna modules of electronic devices. Among them, the antenna module in the related art usually has a fracture on the metal body, so that the metal arms on both sides of the fracture form an antenna radiator, and each antenna radiator provides a resonance mode covering a frequency band. In this way, when the antenna module is required to generate more resonance modes, it will cause too many breaks in the antenna module, and too many breaks will cause the communication performance of the antenna module of the antenna module to decrease. For example, if there are too many fractures, the distance between the two fractures may become smaller, and the isolation between the formed antenna radiators will deteriorate, and so on.

本实施例中，上述第一馈电点F位于开口10和第一金属体的第一馈地点 C之间，使得第一金属体11的开口端A(即第一金属体11位于开口10的一端)至第一馈地点C形成上述第一天线辐射体。In this embodiment, the above-mentioned first feeding point F is located between the opening 10 and the first feeding point C of the first metal body, so that the opening end A of the first metal body 11 (that is, the first metal body 11 is located at the opening 10 One end) to the first feeding point C forms the first antenna radiator.
其中，上述第一金属体11可以产生第一谐振模态，且第一金属体11的长度可以根据第一谐振模态覆盖的频段设置，即第一金属体11的长度适配第一谐振模态覆盖的频段的电长度。The above-mentioned first metal body 11 can generate a first resonance mode, and the length of the first metal body 11 can be set according to the frequency band covered by the first resonance mode, that is, the length of the first metal body 11 is adapted to the first resonance mode.

Specifically, it may be as shown in FIG. 2 The distance from the opening 10 to the first feeding point C is set at about 10 mm.
另外，上述第二金属体12形成第二天线辐射体，即第二金属体12的开口端B(即第二金属体12位于开口10的一端)至第二馈地点D的全部金属体可以作为第二天线辐射体；第二天线辐射体可以覆盖第二谐振模态，且第二金属体的长度可以根据第二谐振模态覆盖的频段设置，即第二金属体12的长度适配第二谐振模态覆盖的频段的电长度。In addition, the above-mentioned second metal body 12 forms a second antenna radiator, that is, all the metal bodies from the opening end B of the second metal body 12 (that is, the end of the second metal body 12 at the opening 10) to the second feeding point D can be used as The second antenna radiator; the second antenna radiator can cover the second resonance mode, and the length of the second metal body can be set according to the frequency band covered by the second resonance mode, that is, the length of the second metal body 12 is adapted to the second The electrical length of the frequency band covered by the resonant mode.
示例性地，上述第二谐振模态覆盖的频段可以为B1、B3、B5、B8、B12、B17、B20或者B41，且上述第二金属体的长度适配第二谐振模态覆盖的频段的电长度，具体地，可以是开口10至第二馈地点D的距离的取值范围为50毫米至60毫米。Exemplarily, the frequency band covered by the second resonance mode may be B1, B3, B5, B8, B12, B17, B20, or B41, and the length of the second metal body is adapted to the frequency band covered by the second resonance mode. The electrical length, specifically, the distance from the opening 10 to the second feed point D may range from 50 mm to 60 mm.
本实施例中，上述第三金属体13与上述第二金属体12间隔设置，且第三金属体13与第二金属体12之间形成耦合缝隙120，使得第三金属体13与第二金属体12形成电容耦合，从而第三金属体13和第二金属体12形成第三天线辐射体。In this embodiment, the third metal body 13 and the second metal body 12 are spaced apart, and a coupling gap 120 is formed between the third metal body 13 and the second metal body 12, so that the third metal body 13 and the second metal body 12 The body 12 forms a capacitive coupling, so that the third metal body 13 and the second metal body 12 form a third antenna radiator.
其中，上述第三天线辐射体可以产生第三谐振模态，且上述第三金属体13可以根据第三谐振模态覆盖的频段调节长度，在一些实施方式中，第三金属体13的长度可以适配第三谐振模态所覆盖的频段的电长度。例如，在上述第三谐振模态覆盖频段N41的情况下，上述第三金属体13的长度适配N41的电长度，且第三金属体13的长度的取值范围可以为10毫米至25毫米。Wherein, the third antenna radiator can generate a third resonance mode, and the third metal body 13 can adjust the length according to the frequency band covered by the third resonance mode. In some embodiments, the length of the third metal body 13 can be Adapt the electrical length of the frequency band covered by the third resonance mode.

另外，上述耦合缝隙120的宽度即第三金属体12与第二金属体12的距离，会影响到第三金属体12与第二金属体12之间的耦合量，耦合缝隙120的宽度越小，第三金属体13与第二金属体12之间的耦合量越大，反之则越 小；而耦合量过大，会导致第一馈源21的辐射性能变差，耦合量过小，会导致第二馈源22的辐射性能提升不明显，故可以根据实际需要设定耦合缝隙120的宽度。In addition, the width of the coupling gap 120, that is, the distance between the third metal body 12 and the second metal body 12, will affect the coupling amount between the third metal body 12 and the second metal body 12. The smaller the width of the coupling gap 120 is , The greater the amount of coupling between the third metal body 13 and the second metal body 12, the smaller the other way around. If the amount of coupling is too large, the radiation performance of the first feed 21 will deteriorate, and if the amount of coupling is too small, As a result, the radiation performance of the second feed source 22 is not significantly improved, so the width of the coupling slot 120 can be set according to actual needs.
在一些实施方式中，第三金属体13与第二金属体12的距离的取值范围为0.3毫米至0.8毫米，从而第二金属体12与第三金属体13之间的耦合量合适，提升第一馈源21和第二馈源22的辐射性能，进而提高天线模组的通信性能。In some embodiments, the distance between the third metal body 13 and the second metal body 12 ranges from 0.3 mm to 0.8 mm, so that the coupling amount between the second metal body 12 and the third metal body 13 is appropriate, which improves The radiation performance of the first feed source 21 and the second feed source 22 further improves the communication performance of the antenna module.
需要说明的是，上述第三金属体13与上述第二金属体12之间各位置的距离可以是不同。例如，上述第三金属体13为球面型的金属体，而第二金属体12为平面型的金属体，从而使得第三金属体13与第二金属体12上各位置的距离可能存在不同。It should be noted that the distance between the positions of the third metal body 13 and the second metal body 12 may be different. For example, the third metal body 13 is a spherical metal body, and the second metal body 12 is a flat metal body, so that the distance between the third metal body 13 and the positions on the second metal body 12 may be different.
在一些实施方式中，第三金属体13可以与第二金属体12平行设置，即第三金属体13与第二金属体12之间各位置的距离相同，从而可以增强第三金属体13与第二金属体12的耦合性能，进而提升天线模组的通信性能。In some embodiments, the third metal body 13 may be arranged in parallel with the second metal body 12, that is, the distance between the third metal body 13 and the second metal body 12 is the same, so that the third metal body 13 and the second metal body 12 can be strengthened. The coupling performance of the second metal body 12 further improves the communication performance of the antenna module.
本实施例中，上述第三金属体13可以是通过柔性电路板(Flexible Printed Circuit Board，FPC)技术或者激光直接成型(Laser-Direct-structuring，LDS)技术等形成的金属，在此并不进行限定。In this embodiment, the third metal body 13 may be a metal formed by flexible printed circuit board (FPC) technology or laser-direct-structuring (LDS) technology. limited.
另外，上述第三金属体13的厚度可以根据实际需要进行设定，具体地，上述第三金属体13的厚度的取值范围为0.05毫米至0.5mm毫米，从而可以保证第三金属体13的可靠性。In addition, the thickness of the third metal body 13 can be set according to actual needs. Specifically, the thickness of the third metal body 13 ranges from 0.05 mm to 0.5 mm, so as to ensure the thickness of the third metal body 13 reliability.
本实施例中，上述第三金属体13与第二金属体12间隔设置，可以是第三金属体13的部分金属体与第二金属体12相对且间隔设置，且第三金属体13的其他部分与上述开口10相对且间隔设置，甚至还可以是第三金属体13的部分金属体与第一金属体11相对且间隔设置。In this embodiment, the third metal body 13 and the second metal body 12 are spaced apart. It may be that part of the metal body of the third metal body 13 is opposite to the second metal body 12 and spaced apart, and other parts of the third metal body 13 Part of the metal body of the third metal body 13 is opposite to the above-mentioned opening 10 and arranged at intervals, and even part of the metal body of the third metal body 13 is opposite to the first metal body 11 and arranged at intervals.
在一些实施方式中，第二金属体12在第三金属体13所在平面的投影覆盖第三金属体13，且第三金属体13与第二金属体12的开口端B的距离d的取值范围为2毫米至10毫米，这样，通过设置第三金属体12与第二金属体12的开口端B的距离d在合适范围内，即设置第三金属体13与开口10的距离在合适范围内，可以提高第一天线辐射体与第三天线辐射体之间的隔离度， 提升天线模组的通信性能，进而提升天线模组的通信性能。In some embodiments, the projection of the second metal body 12 on the plane where the third metal body 13 is located covers the third metal body 13, and the value of the distance d between the third metal body 13 and the open end B of the second metal body 12 The range is 2 mm to 10 mm. In this way, by setting the distance d between the third metal body 12 and the opening end B of the second metal body 12 in a suitable range, that is, setting the distance between the third metal body 13 and the opening 10 in a suitable range Inside, the isolation between the first antenna radiator and the third antenna radiator can be improved, and the communication performance of the antenna module can be improved, thereby improving the communication performance of the antenna module.
本实施例中，上述天线模组可以是仅设置有上述第一金属体11、第二金属体12、第三金属体13、第一馈源21以及第二馈源22，或者，上述天线模组还可以包括其他组件，在此并不进行限定。In this embodiment, the antenna module may be provided with only the first metal body 11, the second metal body 12, the third metal body 13, the first feed 21, and the second feed 22, or the antenna module may The group may also include other components, which are not limited here.
在一些实施方式中，如图2所示，上述天线模组还包括调谐电路31，调谐电路31的第一端与第二金属体12的第一连接点E电连接，调谐电路31的第二端接地，第一连接点E位于第二金属体的开口端B与第二馈地点D之间；In some embodiments, as shown in FIG. 2, the above-mentioned antenna module further includes a tuning circuit 31. The first end of the tuning circuit 31 is electrically connected to the first connection point E of the second metal body 12, and the second connection point E of the tuning circuit 31 is electrically connected. The terminal is grounded, and the first connection point E is located between the open end B of the second metal body and the second feed point D;
调谐电路31用于对第二天线辐射体的低频以及中高频的电容调谐。The tuning circuit 31 is used to tune the low-frequency and mid- and high-frequency capacitances of the second antenna radiator.
这里，调谐电路31可以实现对第二天线辐射体的低频的电感电容调谐以及中高频的电感电容调谐，从而提升第二天线辐射体在低频以及中高频的辐射性能，提升天线模组的通信性能，进而提升电子设备的通信质量。Here, the tuning circuit 31 can realize the low-frequency inductance and capacitance tuning and the middle and high frequency inductance and capacitance tuning of the second antenna radiator, thereby improving the radiation performance of the second antenna radiator at low and medium and high frequencies, and improving the communication performance of the antenna module , And then improve the communication quality of electronic equipment.
其中，上述调谐电路31可以是任何实现对第二天线辐射体的低频的电感电容调谐以及中高频的电容调谐的电路。Wherein, the above-mentioned tuning circuit 31 may be any circuit that realizes low-frequency inductance and capacitance tuning and medium and high-frequency capacitance tuning of the second antenna radiator.
在一些实施方式中，调谐电路31包括开关311，开关311的一端与第二金属体12电连接，开关311的第二端接地。In some embodiments, the tuning circuit 31 includes a switch 311, one end of the switch 311 is electrically connected to the second metal body 12, and the second end of the switch 311 is grounded.
这里，通过设置上述开关311，可以实现在开关311断开的情况下，上述第二金属体12的第一端至第二端之间的金属体形成上述第二天线辐射体；而在开关导通的情况下，上述第二金属体的第一端至开关与第二金属体的连接点之间的金属体形成第四天线辐射体，从而可以增加在同一开口布局的天线辐射体的数量，进一步提升电子设备的通信性能。Here, by providing the switch 311, when the switch 311 is off, the metal body between the first end and the second end of the second metal body 12 forms the second antenna radiator; In the case of communication, the metal body between the first end of the second metal body and the connection point of the switch and the second metal body forms a fourth antenna radiator, so that the number of antenna radiators in the same opening can be increased. Further improve the communication performance of electronic equipment.
当然，上述调谐电路31还可以包括除上述开关311之外的其他部分。例如，上述电容调谐电路31还可以包括与开关311连接的LC电路，通过切换开关可以匹配不同电容电感参数，使第二天线辐射体可以产生覆盖低频、中频以及高频的谐振模态，从而在参数匹配中可以实现低频、中频与高频的载波聚合，尤其是，在第二谐振模态覆盖N41的情况下，可以实现低频、中频与N41的双连接，即E-UTRA为MCG，NR为SCG的双连接(E-UTRA NR dual connectivity with MCG using E-UTRA and SCG using NR，EN-DC)。Of course, the above-mentioned tuning circuit 31 may also include other parts besides the above-mentioned switch 311. For example, the above-mentioned capacitance tuning circuit 31 may also include an LC circuit connected to the switch 311. By switching the switch, different capacitance and inductance parameters can be matched, so that the second antenna radiator can generate resonant modes covering low, intermediate, and high frequencies. Carrier aggregation of low frequency, intermediate frequency and high frequency can be realized in parameter matching, especially when the second resonance mode covers N41, dual connection of low frequency, intermediate frequency and N41 can be realized, that is, E-UTRA is MCG and NR is SCG dual connectivity (E-UTRA NR dual connectivity with MCG using E-UTRA and SCG using NR, EN-DC).
需要说明的是，在上述天线模组设置有上述开关311的情况下，由于第 二馈源在第三天线辐射体上形成固有的频段谐振，如固有的N41频段谐振，在开关切换过程中，固有的频段谐振一直存在，即开关切换对于第二馈源22在第三天线辐射体上形成固有的频段谐振不存在影响。It should be noted that when the antenna module is provided with the switch 311, since the second feed source forms an inherent frequency band resonance on the third antenna radiator, such as an inherent N41 frequency band resonance, during the switching process, The inherent frequency band resonance always exists, that is, switching has no effect on the formation of inherent frequency band resonance by the second feed source 22 on the third antenna radiator.

The first metal body and the second metal body are spaced apart to form an opening. The first metal body has a first feed point and a third metal body. A feeding point, and the first feeding point is located between the opening and the first feeding point; the second metal body has a second feeding point; the third metal body and the second metal body are located between the opening and the second feeding point The metal bodies are arranged at intervals, and the third metal body has a second feeding point, wherein: the first metal body forms the first antenna radiator, the second metal body forms the second antenna radiator, and the third metal body and the second The metal body is coupled to form a third antenna radiator. In this way, the antenna module can realize the layout of at least three antenna radiators in one fracture, which reduces the number of fractures in the antenna module, thereby improving the integrity of the electronic device.

需要说明的是，在上述电子设备还包括金属中框的情况下，上述第一金属体11和第二金属体12可以是电子设备的金属中框上的部分金属体，即电子设备的金属中框上开设有上述开口10，且第一金属体11和第二金属体12为分布于开口10两侧的部分金属体，这样，在金属中框上开设一个开口10即可实现多个谐振模态，在天线模组产生较多的谐振模态时，可以减少金属中框上开设的开口10的数量，从而提升电子设备的整机一体性；另外，上述开口10可以是开设于电子设备的长边或者短边。It should be noted that in the case where the above-mentioned electronic device further includes a metal middle frame, the above-mentioned first metal body 11 and the second metal body 12 may be part of the metal body on the metal middle frame of the electronic device, that is, the metal middle frame of the electronic device The frame is provided with the above-mentioned opening 10, and the first metal body 11 and the second metal body 12 are partial metal bodies distributed on both sides of the opening 10. In this way, opening an opening 10 in the metal middle frame can realize multiple resonance modes. When the antenna module produces more resonant modes, the number of openings 10 opened on the metal middle frame can be reduced, thereby improving the integrity of the electronic device; in addition, the opening 10 may be opened in the electronic device Long side or short side.
当然，在上述电子设备的中框为塑胶材料的结构的情况下，上述第一金属体11和第二金属体12可以是贴设于该电子设备的中框上，等等，在此并不进行限定。Of course, in the case where the middle frame of the electronic device is made of plastic material, the first metal body 11 and the second metal body 12 may be attached to the middle frame of the electronic device, etc., which are not here.
