技术领域Technical field
本发明实施例涉及通信技术领域,尤其涉及一种天线单元及电子设备。The embodiments of the present invention relate to the field of communication technology, and in particular to an antenna unit and electronic equipment.
背景技术Background technique
随着第五代移动通信(5th-Generation,5G)系统的发展,以及电子设备的广泛应用,毫米波天线逐渐被应用在各种电子设备中,以满足用户日益增长的使用需求。With the development of the fifth-generation mobile communication (5th-Generation, 5G) system and the widespread application of electronic devices, millimeter-wave antennas are gradually being used in various electronic devices to meet the increasing use demands of users.
目前,电子设备中的毫米波天线主要通过封装天线(antenna in package,AiP)技术实现。例如,如图1所示,可以通过AiP技术,将工作波长为毫米波的阵列天线11、射频集成电路(radio frequency integrated circuit,RFIC)12、电源管理集成电路(power management integrated circuit,PMIC)13和连接器14封装成一个模块10,该模块10可以称为毫米波天线模组。其中,上述阵列天线中的天线可以为贴片天线、八木-宇田天线,或者偶极子天线等。At present, millimeter wave antennas in electronic devices are mainly implemented through antenna in package (AiP) technology. For example, as shown in Figure 1, AiP technology can be used to integrate the array antenna 11, the radio frequency integrated circuit (RFIC) 12, and the power management integrated circuit (PMIC) 13 with a working wavelength of millimeter wave. And the connector 14 are packaged into a module 10, and the module 10 may be called a millimeter wave antenna module. Wherein, the antenna in the above-mentioned array antenna may be a patch antenna, a Yagi-Uda antenna, or a dipole antenna.
然而,由于上述阵列天线中的天线通常为窄带天线(例如上述列举的贴片天线等),因此每个天线的覆盖频段有限,但是在5G系统中规划的毫米波频段通常比较多,例如以28GHz为主的n257(26.5-29.5GHz)频段和以39GHz为主的n260(37.0-40.0GHz)频段等,因此传统的毫米波天线模组可能无法覆盖5G系统中规划的主流的毫米波频段,从而导致电子设备的天线性能较差。However, because the antennas in the above-mentioned array antennas are usually narrowband antennas (such as the patch antennas listed above), the coverage frequency band of each antenna is limited, but the millimeter wave frequency bands planned in the 5G system are usually more, for example, 28GHz The main n257 (26.5-29.5GHz) frequency band and the 39GHz main n260 (37.0-40.0GHz) frequency band, etc. Therefore, the traditional millimeter wave antenna module may not be able to cover the mainstream millimeter wave frequency band planned in the 5G system. As a result, the antenna performance of the electronic device is poor.
发明内容Summary of the invention
本发明实施例提供一种天线单元及电子设备,以解决现有的电子设备的毫米波天线覆盖的频段较少,导致电子设备的天线性能较差的问题。The embodiments of the present invention provide an antenna unit and an electronic device to solve the problem that the millimeter wave antenna of the existing electronic device covers less frequency bands, resulting in poor antenna performance of the electronic device.
为了解决上述技术问题,本申请是这样实现的:In order to solve the above technical problems, this application is implemented as follows:
第一方面,本发明实施例提供了一种天线单元,该天线单元包括第一金属凹槽,设置在第一金属凹槽底部的第二金属凹槽,设置在第一金属凹槽底部的M个馈电部,以及设置在第一金属凹槽内的M个馈电臂;其中,该M个馈电部中的每个馈电部分别与一个馈电臂的第一端电连接、且与第一金属凹槽和第二金属凹槽均绝缘,且该M个馈电臂按照第一顺序环绕设置在第一金属凹槽内,以及该M个馈电臂中的每个馈电臂均与第二金属凹槽耦合,M为大于1的整数。In the first aspect, an embodiment of the present invention provides an antenna unit. The antenna unit includes a first metal groove, a second metal groove provided at the bottom of the first metal groove, and M provided at the bottom of the first metal groove. Power feeders, and M power feed arms arranged in the first metal groove; wherein each of the M power feeders is electrically connected to the first end of one power feed arm, and It is insulated from the first metal groove and the second metal groove, and the M feed arms are arranged in the first metal groove in a first order, and each of the M feed arms Both are coupled with the second metal groove, and M is an integer greater than 1.
第二方面,本发明实施例提供了一种电子设备,该电子设备包括上述第一方面中的天线单元。In a second aspect, an embodiment of the present invention provides an electronic device, which includes the antenna unit in the above-mentioned first aspect.
在本发明实施例中,天线单元可以包括第一金属凹槽,设置在第一金属凹槽底部的第二金属凹槽,设置在第一金属凹槽底部的M个馈电部,以及设置在第一金属凹槽内的M 个馈电臂;其中,该M个馈电部中的每个馈电部分别与一个馈电臂的第一端电连接、且与第一金属凹槽和第二金属凹槽均绝缘,且该M个馈电臂按照第一顺序环绕设置在第一金属凹槽内,以及该M个馈电臂中的每个馈电臂均与第二金属凹槽耦合,M为大于1的整数。通过该方案,由于馈电臂可以与第二金属凹槽(可以作为天线单元的辐射体)耦合,因此在馈电臂接收到交流信号的情况下,馈电臂可以与第二金属凹槽耦合,从而可以使得第二金属凹槽产生感应电流,进而可以使得馈电臂和第二金属凹槽均辐射一定频率的电磁波;并且由于馈电臂与第二金属凹槽耦合产生的感应电流的电流路径可以有多个(例如从馈电臂到第二金属凹槽再到馈电臂的电流路径,第二金属凹槽上形成的电流路径等电流路径),因此馈电臂上的电流经由第二金属凹槽产生的电磁波的频率也可以有多个,如此可以使得天线单元获得更宽的带宽,从而可以增加天线单元覆盖的频段。以及由于M个馈电臂按照第一顺序环绕设置在第一金属凹槽内,因此可以使得该M个馈电臂中的各个馈电臂之间的距离较大,如此可以减小该M个馈电臂之间的干扰,从而可以提高天线单元的端口的隔离度,进而可以进一步提高天线单元的性能。In the embodiment of the present invention, the antenna unit may include a first metal groove, a second metal groove arranged at the bottom of the first metal groove, M power feeding parts arranged at the bottom of the first metal groove, and M feeding arms in the first metal groove; wherein, each feeding part of the M feeding parts is electrically connected to the first end of one feeding arm, and is connected to the first metal groove and the first end of the feeding arm. The two metal grooves are insulated, and the M feed arms are arranged in the first metal groove in a first order, and each of the M feed arms is coupled with the second metal groove , M is an integer greater than 1. With this solution, since the feeding arm can be coupled with the second metal groove (which can be used as the radiator of the antenna unit), the feeding arm can be coupled with the second metal groove when the feeding arm receives an AC signal , So that the second metal groove can generate an induced current, so that both the feeding arm and the second metal groove can radiate electromagnetic waves of a certain frequency; and the current of the induced current generated by the coupling of the feeding arm and the second metal groove There can be multiple paths (for example, the current path from the feeding arm to the second metal groove to the feeding arm, the current path formed on the second metal groove, etc.), so the current on the feeding arm passes through the first The electromagnetic waves generated by the two metal grooves can also have multiple frequencies, so that the antenna unit can obtain a wider bandwidth, thereby increasing the frequency band covered by the antenna unit. And because the M feed arms are arranged in the first metal groove in the first order, the distance between each of the M feed arms can be made larger, so that the M feed arms can be reduced. The interference between the feeding arms can improve the isolation of the ports of the antenna unit, and further improve the performance of the antenna unit.

Two metal grooves are coupled, and M is an integer greater than 1. With this solution, since the feeding arm can be coupled with the second metal groove (which can be used as the radiator of the antenna unit), the feeding arm can be coupled with the second metal groove when the feeding arm receives an AC signal , So that the second metal groove can generate an induced current, so that both the feeding arm and the second metal groove can radiate electromagnetic waves of a certain frequency; and the current of the induced current generated by the coupling of the feeding arm and the second metal groove There can be multiple paths (for example, the current path from the feeding arm to the second metal groove to the feeding arm, the current path formed on the second metal groove, etc.), so the current on the feeding arm passes through the first The electromagnetic waves generated by the two metal grooves can also have multiple frequencies, so that the antenna unit can obtain a wider bandwidth, thereby increasing the frequency band covered by the antenna unit. And because the M feed arms are arranged in the first metal groove in the first order, the distance between each of the M feed arms can be made larger, so that the M feed arms can be reduced. The interference between the feeding arms can improve the isolation of the ports of the antenna unit, and further improve the performance of the antenna unit.

为了更加清楚地描述本发明实施例提供的天线单元及其工作原理,下面具体以一个天线单元为例,对本发明实施例提供的天线单元发送信号和接收信号的工作原理进行示例性的说明。In order to more clearly describe the antenna unit provided by the embodiment of the present invention and its working principle, the following specifically takes an antenna unit as an example to exemplarily describe the working principle of the antenna unit provided in the embodiment of the present invention for transmitting and receiving signals.
当电子设备发送5G毫米波信号时,电子设备中的信号源会发出交流信号,交流信号可以通过馈电部传输到馈电臂。然后,在馈电臂接收到该交流信号之后,馈电臂可以与第二金属凹槽耦合,使得第二金属凹槽产生感应电流,然后,第二金属凹槽可以向外辐射多个频率的电磁波(由于馈电臂与第二金属凹槽耦合产生的感应电流的电流路径有可以有多 个,例如从馈电臂到第二金属凹槽再到馈电臂的电流路径、第二金属凹槽上形成的电流路径等电流路径等,因此馈电臂上的电流经由第二金属凹槽辐射的电磁波的频率也可以有多个)。如此,电子设备可以通过本发明实施例提供的天线单元发送不同频率的信号。When an electronic device sends a 5G millimeter wave signal, the signal source in the electronic device sends out an AC signal, and the AC signal can be transmitted to the feeding arm through the feeding part. Then, after the feeding arm receives the AC signal, the feeding arm can be coupled with the second metal groove, so that the second metal groove generates an induced current, and then the second metal groove can radiate multiple frequencies outward Electromagnetic waves (the current path of the induced current generated by the coupling between the feeding arm and the second metal groove can be multiple, for example, the current path from the feeding arm to the second metal groove to the feeding arm, the second metal groove The current path and other current paths formed on the groove, so the current on the feeding arm radiates the electromagnetic wave through the second metal groove with multiple frequencies). In this way, the electronic device can transmit signals of different frequencies through the antenna unit provided in the embodiment of the present invention.
又示例性的,本发明实施例中,当电子设备接收5G毫米波信号时,电子设备所处的空间中的电磁波可以激励第二金属凹槽,从而可以使得第二金属凹槽产生感应电流。在第二金属凹槽产生感应电流之后,第二金属凹槽可以与馈电臂耦合,使得馈电臂产生感应电流(即感应的交流信号)。然后,馈电臂可以通过馈电部向电子设备中的接收机输入该交流信号,如此可以使得电子设备接收到其它设备发送的5G毫米波信号。即电子设备可以通过本发明实施例提供的天线单元接收信号。As another example, in the embodiment of the present invention, when the electronic device receives a 5G millimeter wave signal, electromagnetic waves in the space where the electronic device is located can excite the second metal groove, so that the second metal groove can generate an induced current. After the induced current is generated in the second metal groove, the second metal groove may be coupled with the feeding arm, so that the feeding arm generates an induced current (ie, an induced AC signal). Then, the power feeding arm can input the AC signal to the receiver in the electronic device through the power feeding part, so that the electronic device can receive the 5G millimeter wave signal sent by other devices. That is, the electronic device can receive signals through the antenna unit provided in the embodiment of the present invention.

When the return loss is less than -10dB (decibel), the frequency range covered by the antenna unit can be 26.249GHz-40.054GHz, and this frequency range can also include multiple main millimeter wave frequency bands (for example, n257, n260, and n261). In this way, the antenna unit provided by the embodiment of the present invention can cover most of the 5G millimeter wave frequency band, thereby improving the antenna performance of the electronic device.
需要说明的是,本发明实施例中,上述图3中的点a和点b用于标记回波损耗的数值,由图3可见,点a标记的回波损耗的数值为-9.8622dB,点b标记的回波损耗的数值为-10.014dB。It should be noted that in the embodiment of the present invention, the points a and b in Figure 3 above are used to mark the value of return loss. It can be seen from Figure 3 that the value of return loss marked by point a is -9.8622dB. The value of return loss marked b is -10.014dB.
另外,当一个天线单元的回波损耗小于-10dB时,该天线单元不仅可以满足实际使用需求,而且其天线性能也比较优良。即本发明实施例提供的天线单元可以在满足实际使用需求的基础上,保证更加优良的性能。In addition, when the return loss of an antenna unit is less than -10dB, the antenna unit can not only meet actual use requirements, but also its antenna performance is relatively good. That is, the antenna unit provided by the embodiment of the present invention can ensure better performance on the basis of meeting actual use requirements.

Since the feeding arm can be coupled with the second metal groove (which can be used as the radiator of the antenna unit), when the feeding arm receives an AC signal, the feeding arm can be connected with The second metal groove is coupled, so that the second metal groove can generate an induced current, so that both the feeding arm and the second metal groove can radiate electromagnetic waves of a certain frequency; and because the feeding arm is coupled with the second metal groove There can be multiple current paths for the induced current generated (for example, the current path from the feeding arm to the second metal groove to the feeding arm, the current path formed on the second metal groove, etc.), so the feeding The frequency of the electromagnetic wave generated by the current on the arm through the second metal groove can also be multiple, so that the antenna unit can obtain a wider bandwidth, thereby increasing the frequency band covered by the antenna unit. And because the M feed arms are arranged in the first metal groove in the first order, the distance between each of the M feed arms can be made larger, so that the M feed arms can be reduced.

本发明实施例中,由于一个馈电臂组中的馈电臂之间的距离越大,该馈电臂组对其它馈电臂组的影响越小,因此可以通过将上述第一馈电臂、第二馈电臂、第三馈电臂和第四馈电臂沿第一金属凹槽的内侧壁顺序设置在第一金属凹槽内的方式,增大上述两个馈电臂组(第一馈电臂组和第二馈电臂组)中的馈电臂之间的距离,从而在天线单元工作过程中,可以减小这些馈电臂组之间的相互影响,进而可以减小不同极化间的干扰。In the embodiment of the present invention, since the greater the distance between the feeding arms in one feeding arm group, the smaller the influence of the feeding arm group on other feeding arm groups. Therefore, the above-mentioned first feeding arm can be , The second feeding arm, the third feeding arm and the fourth feeding arm are arranged in the first metal groove in sequence along the inner side wall of the first metal groove, increasing the above-mentioned two feeding arm groups (the first The distance between the feeding arms in the one feeding arm group and the second feeding arm group), so that during the working process of the antenna unit, the mutual influence between these feeding arm groups can be reduced, and the difference can be reduced.

需要说明的是,本发明实施例中,当从Z轴反向俯视本发明实施例提供的天线单元时,馈电部是不可见的,因此图5中的馈电部用虚线示意。It should be noted that, in the embodiment of the present invention, when the antenna unit provided in the embodiment of the present invention is viewed from the Z-axis reversely, the feeding part is not visible. Therefore, the feeding part in FIG. 5 is indicated by a dotted line.
当然,实际实现时,上述第一极化和第二极化还可以为其它任意可能的极化形式。具体可以根据实际使用需求确定,本发明实施例不作限定。Of course, in actual implementation, the foregoing first polarization and second polarization may also be any other possible polarization forms. Specifically, it can be determined according to actual use requirements, and the embodiment of the present invention does not limit it.
本发明实施例中,由于上述第一馈电臂组和上述第二馈电臂组可以为两个不同极化(第一极化和第二极化)的馈电臂组,因此可以使得本发明实施例提供的天线单元可以形成一个双极化的天线单元,如此可以提高天线单元的无线连接能力,从而可以减小天线单元通信断线的概率,即可以提高天线单元的通信能力。In the embodiment of the present invention, since the first feed arm group and the second feed arm group may be two feed arm groups with different polarizations (first polarization and second polarization), the current The antenna unit provided by the embodiment of the invention can form a dual-polarized antenna unit, which can improve the wireless connection capability of the antenna unit, thereby reducing the probability of communication disconnection of the antenna unit, that is, improving the communication capability of the antenna unit.

That is, when one feeding arm in the first feeding arm group is in the working state, the other feeding arm in the first feeding arm group may also be in the working state. Correspondingly, when one feeding arm in the second feeding arm group is in the working state, the other feeding arm in the second feeding arm group may also be in the working state.
可选的,本发明实施例中,当第一馈电臂组中的馈电臂处于工作状态时,第二馈电臂组中的馈电臂可能处于工作状态,也可能不处于工作状态。具体可以根据实际使用需求确定,本发明实施例不作限定。Optionally, in the embodiment of the present invention, when the feeding arms in the first feeding arm group are in a working state, the feeding arms in the second feeding arm group may or may not be in a working state. Specifically, it can be determined according to actual use requirements, and the embodiment of the present invention does not limit it.
本发明实施例中,由于天线单元中可以包括两个馈电臂组,因此电子设备可以通过天线单元中的该两个馈电臂组发送信号和接收信号,即可以通过本发明实施例提供的天线单元实现MIMO技术,如此可以提高天线单元的通信容量和通信速率,即可以提高天线单元的数据传输速率。In the embodiment of the present invention, since the antenna unit may include two feeder arm groups, the electronic device can transmit and receive signals through the two feeder arm groups in the antenna unit, that is, it can be provided by the embodiment of the present invention.

可以理解,本发明实施例中,在上述M个馈电臂均位于同一平面上的情况下,该M个馈电臂与设置在上述第一金属凹槽底部的第二金属凹槽之间的距离均相等。It can be understood that, in the embodiment of the present invention, in the case where the foregoing M feeding arms are all located on the same plane, the distance between the M feeding arms and the second metal groove provided at the bottom of the first metal groove is The distances are all equal.
本发明实施例中,由于上述M个馈电臂与第二金属凹槽之间的距离不同,上述M个馈电臂与第二金属凹槽耦合时的耦合参数可能不同,例如上述M个馈电臂与第二金属凹槽耦合产生的感应电流可能不同,因此可以根据天线单元的实际使用需求(例如天线单元覆盖的频率范围),灵活的设置上述M个馈电臂与第二金属凹槽之间的距离。In the embodiment of the present invention, due to the different distances between the M feeding arms and the second metal groove, the coupling parameters when the M feeding arms are coupled to the second metal groove may be different, for example, the M feeding arms may be different from each other. The induced current generated by the coupling between the electric arm and the second metal groove may be different, so the above M feed arms and the second metal groove can be flexibly set according to the actual use requirements of the antenna unit (for example, the frequency range covered by the antenna unit) the distance between.
另外,由于在上述M个馈电臂与第二金属凹槽之间的距离均相等的情况下,可以便于控制该M个馈电臂与第二金属凹槽耦合的参数,例如耦合产生的感应电流等,因此可以通过将该M个馈电臂均设置在同一平面上的方式,使得不同馈电臂与第二金属凹槽之间的距离均相等,如此可以便于控制本发明实施例提供的天线单元的工作状态。In addition, since the distances between the M feeding arms and the second metal groove are all equal, it is convenient to control the coupling parameters of the M feeding arms and the second metal groove, such as the induction caused by the coupling. Therefore, the distances between the different feeding arms and the second metal groove can be equalized by arranging the M feeding arms on the same plane, which can facilitate the control of the method provided by the embodiment of the present invention.

The two feeding parts electrically connected to the electric arm and the fourth feeding arm may be located on the other diagonal line of the first metal groove.
示例性的,如图5所示,与第一馈电臂2040(具体可以为第一馈电臂的第一端)电连接的馈电部2030和与第三馈电臂2041(具体可以为第三馈电臂的第一端)电连接的馈电部2031可以位于第一金属凹槽的第一对角线L1上,与第二馈电臂2042(具体可以为第二馈电臂的第一端)电连接的馈电部2032和与第四馈电臂2043(具体可以为第四馈电臂的第一端)电连接的馈电部2033可以位于第一金属凹槽的第二对角线L2上。如此可以进一步增大第一馈电臂与第三馈电臂之间的距离、第二馈电臂与第四馈电臂之间的距离,从而可以进一步提高天线单元的端口的隔离度。Exemplarily, as shown in FIG. 5, the feeder 2030 electrically connected to the first feeder arm 2040 (specifically the first end of the first feeder arm) and the third feeder arm 2041 (specifically may be The feeding portion 2031 electrically connected to the first end of the third feeding arm may be located on the first diagonal line L1 of the first metal groove, and is connected to the second feeding arm 2042 (specifically, the feeding part 2031 of the second feeding arm). The first end) electrically connected to the feeder 2032 and the fourth feeder arm 2043 (specifically, the first end of the fourth feeder arm) can be located at the second end of the first metal groove. On the diagonal L2. In this way, the distance between the first feeding arm and the third feeding arm, and the distance between the second feeding arm and the fourth feeding arm can be further increased, so that the isolation of the port of the antenna unit can be further improved.
下面再结合图6,对本发明实施例提供的天线单元的隔离度进行示例性的说明。In the following, with reference to FIG. 6, the isolation of the antenna unit provided by the embodiment of the present invention will be exemplarily described.
示例性的,如图6所示,为本发明实施例提供的天线单元工作时,天线单元的极化隔离度示意图。假设第一金属凹槽为矩形凹槽;且第一馈电臂与第三馈电臂组成的馈电臂组为水平极化的馈电臂组,第二馈电臂和第四馈电臂组成的馈电臂组为垂直极化的馈电臂组,以及与第一馈电臂和第三馈电臂电连接的馈电部分布在第一金属凹槽的一条对角线上,与第二馈电臂和第四馈电臂电连接的馈电臂分布在第一金属凹槽的另一条对角线上。那么,如图6所示,在天线单元工作的全频段(即天线单元能够覆盖的所有频段)内,天线单元的端口的隔离度均小于-20dB。然而,通常天线单元的端口隔离度为-10dB即可满足实际使用需求,且天线单元的端口的隔离度越小,天线单元的端口间的相互影响越小,从而可以进一步优化天线单元的极化性能。Exemplarily, as shown in FIG. 6, it is a schematic diagram of the polarization isolation of the antenna unit when the antenna unit provided by the embodiment of the present invention works. Assume that the first metal groove is a rectangular groove; and the feed arm group composed of the first feed arm and the third feed arm is a horizontally polarized feed arm group, the second feed arm and the fourth feed arm The formed feeder arm group is a vertically polarized feeder arm group, and the feeder part electrically connected with the first feeder arm and the third feeder arm is arranged on a diagonal line of the first metal groove, and The feeding arms electrically connected to the second feeding arm and the fourth feeding arm are distributed on the other diagonal line of the first metal groove.

Wherein, the specific distribution mode of the M through holes in the first metal groove may be determined according to the distribution positions of the M power feeding parts in the first metal groove.

可选的,本发明实施例中,上述M个通孔中的每个通孔内可以设置有第三绝缘体,该第三绝缘体可以包裹设置在通孔中的馈电部。Optionally, in the embodiment of the present invention, a third insulator may be provided in each of the above-mentioned M through holes, and the third insulator may wrap the feeder provided in the through hole.

本发明实施例中,第三绝缘体、馈电部以及第一金属凹槽中设置通孔共同构成了特征阻抗为50欧的同轴传输结构,一方面,由于通孔的直径可能大于馈电部的直径,因此当馈电部设置在通孔中时,馈电部可能无法固定在该通孔中,因此通过在通孔中设置上述第三绝缘体,且该第三绝缘体包裹馈电部设置的方式,可以使得馈电部固定在通孔中。另一方面,由于第一金属凹槽和馈电部均为金属材质,在天线单元工作的过程中,两者之间可能会产生接触,因此可以通过在通孔中增加上述第三绝缘体的方式隔离馈电部与第一金属凹槽,使得馈电部与第一金属凹槽绝缘,从而可以使得电子设备的天线性能更加稳定。In the embodiment of the present invention, the third insulator, the feeding part, and the through holes provided in the first metal groove together form a coaxial transmission structure with a characteristic impedance of 50 ohms. On the one hand, the diameter of the through hole may be larger than the feeding part. Therefore, when the power feeder is provided in the through hole, the power feeder may not be fixed in the through hole. Therefore, the third insulator is provided in the through hole, and the third insulator wraps the power feeder. In this way, the power feeding part can be fixed in the through hole. On the other hand, since the first metal groove and the feeding part are made of metal, there may be contact between the two during the operation of the antenna unit. Therefore, the above-mentioned third insulator can be added to the through hole. Isolate the power feeding part and the first metal groove, so that the power feeding part is insulated from the first metal groove, so that the antenna performance of the electronic device can be more stable.
