Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
The embodiment of the present disclosure provides an antenna assembly, and fig. 1 is a schematic structural diagram of an antenna assembly shown according to an exemplary embodiment. As shown in fig. 1, an antenna assembly 10, comprising:
a first metal radiator 11, a second metal radiator 12 and a connecting rib 13;
the first end 11a of the first metal radiator 11 is close to the first end 12a of the second metal radiator 12;
the connecting rib 13 is disposed between the first end portion 11a of the first metal radiator 11 and the first end portion 12a of the second metal radiator 12, and connects the first metal radiator 11 and the second metal radiator 12;
the frequency band range of the first radio frequency signal generated by the first metal radiator 11 is the same as the frequency band range of the second radio frequency signal generated by the second metal radiator 12.
It should be noted that the antenna assembly provided by the embodiments of the present disclosure may be configured in a terminal device, and the antenna assembly is used for radiating and/or receiving a radio frequency signal to implement a communication function of the terminal device. Here, the terminal device may be a mobile terminal or a wearable electronic device, the mobile terminal includes a mobile phone, a notebook, and a tablet computer, and the wearable electronic device includes a smart watch, and the embodiments of the present disclosure are not limited thereto.
The antenna assembly may include a first metal radiator and a second metal radiator, wherein a frequency band range of a first radio frequency signal generated by the first metal radiator is the same as or similar to a frequency band range of a second radio frequency signal generated by the second metal radiator. For example, the first metal radiator and the second metal radiator may receive or transmit signals of a 6G band.
In the embodiment of the present disclosure, any one of the first metal radiator and the second metal radiator may be selected for signal transmission.
Here, different metal radiators can be selected for signal transmission according to different attitudes of the antenna assembly.
For example, if the antenna assembly is disposed in a terminal device, and the first metal radiator and the second metal radiator are located at different positions of the terminal device; the attitude of the antenna assembly can be determined according to the screen display attitude of the terminal device, and then one of the first metal radiator and the second metal radiator is selected for signal transmission.
It can be understood that, in consideration of different postures of the antenna assembly, there may be a case where the first metal radiator or the second metal radiator is shielded and cannot normally operate; according to the attitude of the antenna assembly, the metal radiator which is possibly shielded can be determined, and another metal radiator is selected for signal transmission, so that the stability of the signal transmission of the antenna assembly is improved.
In other embodiments, the first rf signal and the second rf signal in the same frequency band range may be transmitted simultaneously through the first metal radiator and the second metal radiator.
It can be understood that, the first metal radiator and the second metal radiator transmit the radio frequency signals in the same frequency band range together, so that the radiation efficiency of the antenna assembly in the frequency band range can be effectively improved.
Because the frequency band range of the first radio frequency signal generated by the first metal radiator is the same as the frequency band range of the second radio frequency signal generated by the second metal radiator, when the first metal radiator and the second metal radiator receive and transmit signals of the same frequency band at the same time, the first metal radiator and the second metal radiator need to be decoupled.
In an embodiment of the present disclosure, the first metal radiator and the second metal radiator may be a metal sheet or a metal bezel. The metal radiator may be rectangular, regular polygonal, L-shaped, or the like.
It should be noted that the dual antenna structure in the related art generally adopts a combination of a metal radiator and a non-metal radiator, for example, a frame antenna and an antenna formed by a Laser Direct Structuring (LDS) process constitute the dual antenna structure. On one hand, the antenna performance of the nonmetal radiator, such as bandwidth characteristic, radiation characteristic and the like, is inferior to that of the metal radiator; on the other hand, the decoupling between the non-metallic radiator and the metallic radiator is complex.
Based on this, the first metal radiator and the second metal radiator are adopted to form the antenna assembly in the form of the double antenna, so that on one hand, the antenna performance of the antenna assembly, such as bandwidth characteristics and radiation characteristics, can be improved, and on the other hand, the decoupling complexity between the two radiators can be reduced.
The first metal radiator and the second metal radiator each include: a first end and a second end; the first end of the first metal radiator is close to the first end of the second metal radiator; the second end part of the first metal radiator is one end, far away from the second metal radiator, in the first metal radiator; the second end of the second metal radiator is the end of the second metal radiator far away from the first metal radiator.
And connecting the first end part of the first metal radiator and the second end part of the second metal radiator through the connecting rib.
Here, the connection rib may be made of a metal material. In some embodiments, the first metal radiator, the second metal radiator, and the connection rib may be formed by a metal bezel of a terminal device.
Considering that the distance between the first end of the first metal radiator and the first end of the second metal radiator is relatively short, there may be signal interference between the first radio frequency signal generated by the first metal radiator and the second radio frequency signal generated by the second metal radiator.
The connection rib may be connected to a ground terminal, and is configured to return a current of the first end of the first metal radiator and a current of the first end of the second metal radiator to the ground, so that the first metal radiator and the second metal radiator do not interfere with each other, and isolation between the first metal radiator and the second metal radiator is improved.
According to the embodiment of the disclosure, the connection rib is arranged between the first end of the first metal radiator and the first end of the second metal radiator, and the first metal radiator and the second metal radiator are connected through the connection rib, so that signal interference between a first radio frequency signal and a second radio frequency signal is reduced; on the basis of reducing the distribution space of the antenna assembly, the mutual influence among different metal radiators in the antenna assembly is reduced.
Optionally, as shown in fig. 2, fig. 2 is a schematic structural diagram two of an antenna assembly shown according to an exemplary embodiment. The antenna assembly 10, comprising:
a first feeding point 14 and a second feeding point 15;
the first feeding point 14 is located on the first metal radiator 11 and located at the second end 11b of the first metal radiator 11;
the second feeding point 15 is located on the second metal radiator 12 and located at the second end 12b of the second metal radiator 12.
In an embodiment of the present disclosure, the first metal radiator includes a first feeding point; the first feed point can be electrically connected with a feed source, and the feed source feeds an electric signal into the first feed point to excite the first metal radiator to radiate a first radio frequency signal.
The second metal radiator comprises a second feed point, the second feed point can be electrically connected with the feed source, and the feed source feeds an electric signal into the second feed point to excite the second metal radiator to radiate a second radio frequency signal.
The first feed point may be located at a second end portion of the first metal radiator away from the second metal radiator; the second feeding point may be located at a second end portion of the second metal radiator distant from the first metal radiator.
It should be noted that, by disposing the feeding point at the end of the branch of the metal radiator, the operating bandwidth of the metal radiator can be effectively increased.
Optionally, as shown in fig. 3-4, fig. 3 is a schematic structural diagram three of an antenna assembly shown according to an exemplary embodiment; fig. 4 is a fourth structural schematic diagram illustrating an antenna assembly in accordance with an exemplary embodiment.
The antenna assembly 10, comprising: a third feeding point 16;
the third feeding point 16 is disposed on the first metal radiator 11 adjacent to the first feeding point 14;
alternatively, the third feeding point 16 is disposed on the second metal radiator 12 adjacent to the second feeding point 15.
In the embodiment of the present disclosure, the number of feeding points on a metal radiator is related to an antenna scheme corresponding to the metal radiator.
In order to simultaneously consider the antenna performance of the antenna assembly and the layout condition of the antenna assembly, the first metal radiator or the second metal radiator can adopt an antenna scheme in a double-feed-point mode.
It can be understood that the dual-feed antenna can generate radio frequency signals in two different frequency band ranges, thereby improving the bandwidth characteristics of the antenna. For example, radio frequency signals of a high band range and a low band range may be generated simultaneously.
The setting position of the third feeding point may be determined according to the branch distribution of the first metal radiator and the second metal radiator, and/or the priority of the first metal radiator and the second metal radiator.
For example, if the first metal radiator has a longer branch and the second metal radiator has a shorter branch, the third feeding point may be disposed on the first metal radiator, and the third feeding point is adjacent to the first feeding point.
For another example, if the priority of the first metal radiator is higher than that of the second metal radiator, that is, the first metal radiator is a main radiator, the third feeding point may be disposed on the first metal radiator, and the third feeding point is adjacent to the first feeding point.
In some embodiments, the first feeding point and the third feeding point are disposed on the first metal radiator at an interval, and the first feeding point is located at the second end of the first metal radiator; the second feeding point is arranged on the second metal radiator, and the second feeding point is located at the second end of the second metal radiator.
The first metal radiator can be excited to generate electromagnetic wave signals of a WIFI 5G frequency band and a WIFI 6E frequency band by feeding a first excitation current to a first feed point of the first metal radiator; a second excitation current may be fed to a third feeding point of the first metal radiator to excite the first metal radiator to generate an electromagnetic wave signal of a WIFI 2.4G frequency band.
And feeding a third excitation current to a second feed point of the second radiator to excite the second metal radiator to generate electromagnetic wave signals of a WIFI 2.4G frequency band, a WIFI 5G frequency band and a WIFI 6E frequency band.
In order to verify the change of the feeding point setting position on the antenna assembly performance, antenna performance parameters of the antenna assemblies at different feeding point positions can be compared. For convenience of description, an antenna assembly in which a feeding point is disposed at an end of a branch of the metal radiator is referred to as a first antenna assembly, and an antenna assembly in which a feeding point is not disposed at an end of a branch of the metal radiator (a distance between the feeding point and the end of the branch is 1 mm) is referred to as a second antenna assembly. The working frequency bands of the first antenna assembly and the second antenna assembly are both a WIFI 2.4G frequency band, a WIFI 5G frequency band and a WIFI 6E frequency band.
As shown in fig. 5, fig. 5 is a comparative schematic diagram of the Smith circles of antenna assemblies shown at different feed point locations in accordance with an exemplary embodiment. Wherein, with the same matching topology, the 3/4 wavelength mode of the current is close to the half-wave mode when the feeding point is located at the end, so that the Smith chart of the first antenna assembly converges more at 5.2GHz-7GHz and is located closer to the middle point of 50 Ω (i.e., the intrinsic impedance value).
As shown in fig. 6, fig. 6 is a comparative schematic diagram illustrating S-parameters of antenna assemblies at different feed point locations according to an exemplary embodiment. As can be seen from FIG. 6, the first antenna assembly has a depth of resonance less than-10 dB at 5.2GHz-7GHz, whereas the stacked antenna assembly has a depth of resonance less than-10 dB only after 6.5 GHz.
In other embodiments, the antenna assembly includes:
a third feeding point and a fourth feeding point;
the third feeding point and the first feeding point are arranged on the first metal radiator in an adjacent mode; the fourth feeding point and the second feeding point are adjacently arranged on the second metal radiator.
In the embodiment of the present disclosure, the first metal radiator and the second metal radiator may both adopt an antenna scheme in a dual feed point form, so that the antenna performance of the antenna assembly is effectively improved.
Optionally, as shown in fig. 7, fig. 7 is a schematic structural diagram five of an antenna assembly shown according to an exemplary embodiment. The first metal radiator 11 includes:
a first radiating branch 111 and a second radiating branch 112;
the second radiation branch 112 is bent relative to the first radiation branch 111, and is connected to the first radiation branch 111.
In an embodiment of the present disclosure, the first metal radiator includes: the radiation device comprises a first radiation branch and a second radiation branch connected with the first radiation branch; and the second radiating branch may be bent with respect to the first radiating branch.
Through setting up first metal radiator for the first radiation minor matters and the second radiation minor matters that link to each other to the second radiation minor matters is buckled for first radiation minor matters, so when disposing the antenna module in terminal equipment, can utilize terminal equipment's apex angle region to carry out the overall arrangement, improves terminal equipment's space utilization.
Optionally, as shown in fig. 7, the second radiation branch 112 forms a first end 11a of the first metal radiator 11, and the first radiation branch 111 forms a second end 11b of the first metal radiator 11;
the second metal radiator 12 and the second radiation branch 112 extend in the same direction.
In an embodiment of the present disclosure, the first radiating branch forms a second end of the first metal radiator, and the first feeding point is disposed on the first radiating branch;
the second radiation branch forms a first end of the first metal radiator, and the second metal radiator and the second radiation branch extend in the same direction, that is, the second radiation branch and the second metal radiator may be located on the same straight line, for example, the second radiation branch and the second metal radiator may be located at a side edge of a metal frame of a terminal device.
The second radiation branch is connected with the first end part of the second metal radiation body through the connecting rib, and the second feed point of the second metal radiation body is arranged at the second end part of the second metal radiation body.
Therefore, the lengths of the first metal radiating body and the second metal radiating body in the antenna assembly can be increased, and the working frequency band of the antenna assembly can be widened.
Alternatively, as shown in fig. 8, fig. 8 is a schematic structural diagram six of an antenna assembly shown according to an exemplary embodiment.
The antenna assembly 10, comprising:
an elastic conductive member 17 disposed on the connecting rib 13;
wherein, the connecting rib 13 is connected with the metal plate of the display screen through the elastic conductive piece 17.
In the embodiment of the present disclosure, the connecting rib is provided with an elastic conductive member; after the antenna assembly is configured in a terminal device, the elastic conductive piece is arranged between the connecting rib and the display screen, and one side of the elastic conductive piece elastically abuts against the connecting rib; the other side elastically butts against the metal plate of the display screen, so that the first metal radiator and the second metal radiator connected by the connecting ribs can respectively form a signal loop, and the isolation between the first metal radiator and the second metal radiator is improved.
Here, the elastic conductive member may be a conductive foam, a conductive silicone gasket, a conductive film, or the like. The elastic conductive piece has conductive performance and can generate elastic deformation compression under the action of pressure, so that the elastic conductive piece can urgently abut against the connecting rib and the metal plate tightly abutting against the display screen.
Considering that the frequency band ranges of the first radio frequency signal generated by the first metal radiator and the second radio frequency signal generated by the second metal radiator are the same, there may be signal interference between the first metal radiator and the second metal radiator.
Therefore, the elastic conductive part is arranged at the connecting rib, and the connecting rib is connected with the metal plate of the display screen through the elastic conductive part, so that the first metal radiator and the second metal radiator can respectively form a signal loop, the first metal radiator and the second metal radiator do not interfere with each other, and the isolation between the first metal radiator and the second metal radiator is improved.
For example, in order to verify the influence of the position of a feed point and the elastic conductive member on the isolation between metal radiators in an antenna assembly, isolation contrast can be performed on the antenna assembly in different situations. For convenience of description, the feeding point may be disposed at the end of the branch of the metal radiator, and the antenna assembly where the elastic conductive member is not disposed at the connection rib is referred to as a first antenna assembly, and the feeding point is not disposed at the end of the branch of the metal radiator (the distance between the feeding point and the end of the branch is 1 mm), and the antenna assembly where the elastic conductive member is not disposed at the connection rib is referred to as a second antenna assembly; the feed point is arranged at the tail end of the branch of the metal radiator, and the antenna component with the elastic conductive piece arranged at the connecting rib is the third antenna component. The working frequency bands of the first antenna assembly, the second antenna assembly and the third antenna assembly are all WIFI 2.4G frequency bands, WIFI 5G frequency bands and WIFI 6E frequency bands.
As shown in fig. 9, fig. 9 is an isolation contrast diagram of an antenna assembly illustrating a plurality of different scenarios in accordance with an exemplary embodiment. As can be seen from fig. 9, the isolation of the first antenna element is slightly better than that of the second antenna element, and the difference in isolation between the first antenna element and the second antenna element is determined by the distance between the feed point and the end of the branch of the metal radiator.
Compared with the first antenna component and the second antenna component, the isolation of the third antenna component is greatly improved; and the isolation of the third antenna assembly in the frequency range of WIFI 5G and WIFI 6E is less than-20 dB. It can be understood that, because the elastic conductive piece at the joint rib is connected with the grounding end, a zero potential is introduced at the joint rib to interfere the current trend at the joint rib originally, so that the current of the two metal radiators in the third antenna assembly flows to the zero potential, and the mutual influence between the two metal radiators is avoided.
Further illustratively, in order to verify the influence of the position of a feed point and the elastic conductive member on the radiation efficiency between the metal radiators in the antenna assembly, antenna radiation efficiency comparison can be performed on the antenna assemblies in different situations. For convenience of description, the feeding point may be disposed at the end of the branch of the metal radiator, and the antenna assembly where the elastic conductive member is not disposed at the connection rib is denoted as a first antenna assembly; the feed point is arranged at the tail end of the branch of the metal radiator, and the antenna component with the elastic conductive piece arranged at the connecting rib is the third antenna component; the feed point is not arranged at the tail end of the branch of the metal radiator (the distance between the feed point and the tail end of the branch is 1 mm), and the antenna component with the elastic conductive piece arranged at the connecting rib is the fourth antenna component.
As shown in fig. 10, fig. 10 is a radiation efficiency comparison schematic diagram illustrating antenna assemblies for a plurality of different situations according to an exemplary embodiment. As can be seen from fig. 10, the radiation efficiency of the third antenna assembly is optimal, the peak value of the radiation efficiency is about-4.3 dB in the frequency band range of 5GHz-7GHz, and the valley value is not less than-7.5 dB.
As can be seen from a comparison between the radiation efficiency curve of the third antenna element and the radiation efficiency curve of the fourth antenna element, when the feeding point is far away from the end of the branch of the metal radiator, the radiation efficiency of the antenna assembly is gradually decreased, and the difference between the radiation efficiency of the third antenna element and the radiation efficiency of the fourth antenna element is determined by the distance between the feeding point and the end of the branch of the metal radiator.
According to the comparison between the radiation efficiency curve of the first antenna component and the radiation efficiency curve of the third antenna component, compared with the radiation efficiency of the first antenna component, the radiation efficiency of the third antenna component is improved by about 1.5 dB; it can be seen that the elastic conductive elements at the connection ribs have a significant influence on the two metal radiating elements in the antenna assembly.
Optionally, the first metal radiator and the second metal radiator are any one of radiators of a WIFI antenna, a LTE antenna, a millimeter wave antenna, a GPS antenna, a GSM antenna, and a bluetooth antenna.
In the embodiment of the present disclosure, the first metal radiator and the second metal radiator may be any one of a radiator of a WIFI antenna, a radiator of an LTE antenna, a radiator of a millimeter wave antenna, a radiator of a GPS antenna, a radiator of a GSM antenna, and a radiator of a bluetooth antenna; the first metal radiator and the second metal radiator can be used for radiating any one of WIFI signals, LTE signals, millimeter wave signals, GPS signals, GSM signals and Bluetooth signals.
In some embodiments, the first metal radiator and the second metal radiator are one or more of a radiator of a WIFI antenna and a radiator of a bluetooth antenna.
It can be understood that, since the frequency band range of the bluetooth signal is the same as the frequency band range of the WIFI signal, both the first metal radiator and the second metal radiator are used for radiating the WIFI signal, or both the first metal radiator and the second metal radiator are used for radiating the bluetooth signal; still alternatively, the first metal radiator and the second metal radiator are respectively used for radiating bluetooth signals and WIFI signals.
An embodiment of the present disclosure provides a terminal device, including:
the antenna assembly shown in one or more of the above claims;
a metal bezel to form the first metal radiator and the second metal radiator.
In this disclosure, the terminal device may be a mobile terminal or a wearable electronic device, where the mobile terminal includes a mobile phone, a notebook, and a tablet computer, and the wearable electronic device includes a smart watch, and the disclosure is not limited in this disclosure.
It can be understood that the first metal radiator, the second metal radiator and the connecting rib are all part of a metal frame of the terminal device, and radiation is performed through the metal frame to achieve communication of the terminal device.
According to the wireless signal receiving requirement of the terminal device and the design requirement of the shell of the terminal device, the first feed point and/or the third feed point of the first metal radiator and the second feed point of the second metal radiator can be arranged at the upper end of the metal frame.
Here, the upper end position may be a position of the metal bezel near an edge of the bezel.
In some embodiments, the first metal radiator is disposed on the top of the metal bezel; the second metal radiator is disposed on one side of the metal bezel.
Illustratively, fig. 11 is a schematic diagram illustrating current patterns of an antenna assembly within a terminal device according to an exemplary embodiment. As shown in fig. 11 (the second metallic radiator is not shown in fig. 11), the arrows indicate the flow of current in the antenna assembly.
According to the terminal equipment, the metal middle frame of the terminal equipment is directly used as the first metal radiator and the second metal radiator, so that on one hand, the influence of an antenna assembly on the screen occupation ratio of the terminal equipment can be reduced, and the display area and the whole display effect of the screen of the terminal equipment are improved; on the other hand, the antenna performance of the antenna assembly, such as bandwidth characteristics, radiation characteristics and the like, can be effectively improved, and the decoupling complexity between two radiators in the antenna assembly is reduced.
And the first metal radiator and the second metal radiator are connected through the connecting rib, and the radio frequency signal is received and reflected by the connecting rib, so that the mutual influence between the first metal radiator and the second metal radiator is reduced.
Optionally, the apparatus, comprises:
the display screen is arranged on the metal frame, and the metal plate of the display screen is connected with the elastic conductive piece on the connecting rib.
As shown in fig. 12, fig. 12 is a schematic partial structure diagram of a metal bezel of a terminal device according to an exemplary embodiment. The apparatus further comprises: a display screen (not shown in fig. 12) carried on the metal bezel 110. And the display screen is located at one side of the metal frame 110. The elastic conductive piece 17 is arranged between the connecting rib 13 and the display screen, and one side of the elastic conductive piece 17 elastically abuts against the connecting rib 13; the other side elastically abuts against a metal plate of the display screen, so that the first metal radiator 11 and the second metal radiator 12 can respectively form a signal loop, thereby increasing the isolation between the first metal radiator 11 and the second metal radiator 12.
Here, the elastic conductive member may be a conductive foam, a conductive silicone gasket, a conductive film, or the like.
