Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present application, and as shown in fig. 1, the electronic device includes:
the feed source 10 is electrically connected to the first radiator 20 and the second radiator 30, the first end of the second radiator 30 is adjacent to the first end of the first radiator 20 and is arranged at an interval, the second end of the second radiator 30 is arranged in an insulating manner with the conductive part 40 of the electronic device, and currents of the first radiator 20 and the second radiator 30 are in the same direction.
The working principle of the embodiment of the application can be referred to as the following expression:
since the electronic device includes the first radiator 20 and the second radiator 30, the length of the radiator of the electronic device is extended, and the radiation performance of the electronic device is improved, so that the communication effect of the electronic device is better. Meanwhile, when the human body is close to the first radiator 20 or the second radiator 30, since the second radiator 30 is spaced apart from the first radiator 20, it can be ensured that the efficiency of one of the first radiator 20 and the second radiator 30 is not affected by the human body, thereby reducing the influence of the human body on the communication effect of the electronic device.
The feed source 10 may further be connected to a radio frequency front end circuit of the electronic device, and at least one of functional circuits such as an antenna matching circuit and a radio frequency tuning switch may be further included between the radio frequency front end circuit and the feed source 10.
Here, the mounting positions of the first radiator 20 and the second radiator 30 are not limited herein, and as an alternative embodiment, referring to fig. 3, the first radiator 20 and the second radiator 30 may be mounted at one end (i.e., a region a in fig. 3) of the electronic device. That is, the first radiator 20 and the second radiator 30 may be mounted on a case 70 of the electronic device, and the case 70 may also be referred to as a metal bezel or the like.
It should be noted that the type of the conductive member 40 of the electronic device is not limited herein, and when the first radiator 20 and the third radiator 30 are located on the housing 70, the conductive member 40 may be a member having a conductive property on the housing 70.
The first radiator 20 and the second radiator 30 may form part of a component of the electronic device, for example: the first radiator 20 and the second radiator 30 may be a part of a metal frame or a metal cover, so that there is no need to reserve a separate installation space for the first radiator 20 and the second radiator 30 on the electronic device, and thus, the arrangement space of components of the electronic device may be reduced, and the volume of the whole electronic device may be reduced.
In addition, the specific types of the first radiator 20 and the second radiator 30 are not limited herein, for example: the first radiator 20 and the second radiator 30 may be implemented in the form of conductor traces, such as Liquid Crystal Polymer (LCP), Modified Polyimide (MPI), Laser-Direct-structuring (LDS), Flexible Printed Circuit Board (FPC), and Printed Circuit Board (PCB).
The shapes of the first radiator 20 and the second radiator 30 are not limited herein, for example: the first radiator 20 and the second radiator 30 may be both linear structures, or the first radiator 20 and the second radiator 30 may be both curved structures. Of course, the first radiator 20 may have a straight structure, and the second radiator 30 may have an arc structure. It should be noted that, when the first radiator 20 and the second radiator 30 are both linear structures, the length of the first radiator 20 may be greater than the length of the second radiator 30.
Here, the connection position between the feed source 10 and the first radiator 20 is not limited, for example: the connection location between the feed 10 and the first radiator 20 (which may be referred to as a first connection point) may be a first end of the first radiator 20, a middle location of the first radiator 20, or a location on the first radiator 20 near the first end of the first radiator 20.
In addition, the connection position between the feed source 10 and the second radiator 30 is not limited here, for example: the connection location between the feed 10 and the first radiator 20 (which may be referred to as a third connection point) may be a second end of the second radiator 30, an intermediate location of the second radiator 30, or a location on the second radiator 30 near the second end of the second radiator 30.
It should be noted that when the currents on the first radiator 20 and the second radiator 30 are in the same direction, the radiation performance of the first radiator 20 and the second radiator 30 can be enhanced, for example: referring to fig. 4 and 5, arrows in fig. 4 and 5 indicate the flow direction of current on the first radiator 20 and the second radiator 30, wherein fig. 4 is a schematic diagram illustrating the distribution of current on the first radiator 20 and the second radiator 30 when a human body is not close to the electronic device, and the radiation performance of the whole electronic device is enhanced because the current on the first radiator 20 and the current on the second radiator 30 are in the same direction. Fig. 5 is a schematic diagram illustrating the distribution of current on the first radiator 20 and the second radiator 30 when the human body 60 is close to the second radiator 30, and it can be seen that when the human body 60 is close to the second radiator 30, the current on the second radiator 30 is reduced (i.e., the arrow corresponding to the current on the second radiator 30 in fig. 5 becomes smaller), but the current on the first radiator 20 is less affected, so that the radiation performance of the electronic device can be ensured.
In addition, the feed source 10 may be connected to the first radiator 20 through a first feed port, the feed source 10 may be connected to the second radiator 30 through a second feed port, and the first feed port and the second feed port may be conductors, so that the feeding effect of the feed source 10 to the first radiator 20 and the second radiator 30 may be further enhanced.
It should be noted that, in order to ensure that the currents on the first radiator 20 and the second radiator 30 are in the same direction, the connection point of the feed 10 and the first radiator 20 and the second radiator 30 may be arranged at the following position:
as an optional implementation manner, a connection point of the feed 10 and the first radiator 20 is a first connection point, a connection point of the feed 10 and the second radiator 30 is a second connection point, a distance between the first connection point and the first end of the first radiator 20 is smaller than a distance between the first connection point and the second end of the first radiator 20, and a distance between the second connection point and the first end of the second radiator 30 is larger than a distance between the second connection point and the second end of the second radiator 30.
The above scheme can also be understood as follows: the first connection point may be disposed near a first end of the first radiator 20, and the second connection point may be disposed near a second end of the second radiator 30.
Thus, through the above arrangement, the currents on the first radiator 20 and the second radiator 30 can be ensured to be in the same direction, and the radiation performance of the electronic device is ensured to be better.
As an alternative embodiment, the second connection point is located at the second end of the second radiator 30. In this way, since the second connection point is located at the second end of the second radiator 30, the current can flow from the second end of the second radiator 30 to the first end of the second radiator 30, so as to further ensure that the current on the second radiator 30 and the current on the first radiator 20 are in the same direction, thereby further enhancing the radiation performance of the electronic device.
As an alternative embodiment, the first connection point is located at the first end of the first radiator 20. In this way, since the first connection point is located at the first end of the first radiator 20, the current can flow from the first end of the first radiator 20 to the second end of the first radiator 20, and it is further ensured that the current on the first radiator 20 and the current on the second radiator 30 are in the same direction, thereby further enhancing the radiation performance of the electronic device.
As an alternative implementation, referring to fig. 1-2 and fig. 4-9, the electronic device further includes a first radio frequency switch 21, where the first radio frequency switch 21 is connected to the first radiator 20, and the first radio frequency switch 21 is configured to adjust a coverage frequency band of the first radiator 20. In this way, the coverage frequency band of the first radiator 20 can be adjusted by the first rf switch 21, thereby improving the degree of freedom of frequency modulation of the first radiator 20.
It should be noted that the first rf switch 21 may be connected to the first radiator 20 through an rf port, and the rf port may be referred to as a conductor, so that the signal transmission effect between the first rf switch 21 and the first radiator 20 may be enhanced.
As an alternative implementation, referring to fig. 1-2 and 4-9, a connection point of the feed 10 and the first radiator 20 is a first connection point, a connection point of the first radio frequency switch 21 and the first radiator 20 is a third connection point, and the first connection point is located between the third connection point and the first end of the first radiator 20. In this way, since the first connection point is closer to the first end of the first radiator 20 than the third connection point, the first rf switch 21 can better adjust the coverage frequency band of the first radiator 20, and compared with a mode in which the first rf switch 21 is closer to the second radiator 30, the influence of the first rf switch 21 on the second radiator 30 can be reduced.
In addition, when the second connection point of the feed source 10 and the second radiator 30 is close to the second end of the second radiator 30, it can be ensured that the current flows in the same direction on the first radiator 20 and the second radiator 30, see fig. 1-2 and fig. 4-9, so that the radiation signals generated by the first radiator 20 and the second radiator 30 can be enhanced by mutual coupling.
As an optional implementation manner, referring to fig. 2 and fig. 7, the electronic device further includes a second radio frequency switch 31, where the second radio frequency switch 31 is connected to the second radiator 30, and the second radio frequency switch 31 is configured to adjust a coverage frequency band of the second radiator 30. In this way, the coverage frequency band of the second radiator 30 can be adjusted by the second rf switch 31, so that the degree of freedom of frequency modulation of the second radiator 30 is improved.
As an alternative implementation, referring to fig. 1 and 2, and fig. 6 and 7, the feed 10 is electrically connected to the second radiator 30 through a conductor trace 32, and the second rf switch 31 is electrically connected to the conductor trace 32. In this way, the feed source 10 feeds the second radiator 30 through the conductor trace 32, so that the feeding effect of the feed source 10 on the second radiator 30 can be enhanced.
The conductor routing 32 can adopt conductors such as an FPC or a metal piece, so that the good conductive effect can be ensured, and meanwhile, the use cost of the conductor routing 32 can be reduced.
It should be noted that the second rf switch 31 may be electrically connected to the conductor trace 32 through an rf port, and the rf port may be a conductor, so that the signal transmission performance between the second rf switch 31 and the conductor trace 32 may be enhanced.
As an alternative implementation, referring to fig. 1-2 and 4-9, a connection point of the feed 10 and the second radiator 30 is a second connection point, and a distance between the second connection point and a first end of the second radiator 30 is greater than a distance between the second connection point and a second end of the second radiator 30. In this way, since the second connection point is closer to the second end of the second radiator 30 than to the first end of the second radiator 30, the feed 10 has less influence on the first radiator 20 when feeding the second radiator 30.
Meanwhile, when the first connection point is close to the first end of the first radiator 20, it may be ensured that the currents on the first radiator 20 and the second radiator 30 are in the same direction, so that the radiation signals generated by the first radiator 20 and the second radiator 30 may be enhanced by mutual coupling.
As an alternative implementation, referring to fig. 6 to 9, the electronic device further includes a third radiator 50, where the third radiator 50 is adjacent to and spaced apart from the second end of the first radiator 20, and the third radiator 50 is coupled to the second end of the first radiator 20. In this way, the first radiator 20 and the third radiator 50 can be coupled to each other, and the length of the radiator of the electronic device and the effective aperture of the radiator are further increased, so that the radiation performance of the electronic device is further enhanced.
In addition, when a user approaches one of the first radiator 20, the second radiator 30 and the third radiator 50, it is ensured that the radiation performance of the remaining two radiators is not affected, thereby ensuring that the radiation performance of the electronic device is good.
In addition, referring to fig. 8 and 9, arrows in fig. 8 and 9 indicate a flowing direction of current on the first radiator 20 and the second radiator 30, wherein fig. 8 illustrates a distribution of current on the first radiator 20 and the second radiator 30 when a human body is not close to the electronic device. Fig. 9 is a schematic diagram illustrating the distribution of current on the first radiator 20 and the second radiator 30 when the human body 60 is close to the second radiator 30 and the third radiator 50, and it can be seen that when the human body 60 is close to the second radiator 30 and the third radiator 50, the current on the second radiator 30 is reduced (i.e. the arrow corresponding to the current on the second radiator 30 in fig. 5 is reduced), but the current on the first radiator 20 is less affected, so that the radiation performance of the electronic device can be ensured.
Here, the third radiator 50 may be disposed to be insulated from the conductive member 40 included in the electronic device, for example: the third radiator 50 may be spaced apart from the second radiator 30, and the third radiator 50 may also be spaced apart from the other conductive members 40.
Of course, the positions of the first radiator 20, the second radiator 30, and the third radiator 50 are not limited herein. For example: the first radiator 20, the second radiator 30, and the third radiator 50 may be disposed at one end edge of a display screen or a case of the electronic device.
As an alternative embodiment, referring to fig. 6 to 9, the second radiator 30 and the third radiator 50 are both located at a corner of the housing of the electronic device.
When a user holds the electronic device, the second radiator 30 and the third radiator 50 are both located at the corners of the housing, so that the probability that the user's hand contacts the second radiator 30 and the third radiator 50 is reduced, and the phenomenon that the radiation performance of the electronic device is reduced due to the contact of the user's hand with the second radiator 30 and the third radiator 50 is reduced. Meanwhile, when the second radiator 30 and the third radiator 50 are both located at the corner of the housing, the radiator of the electronic device may have good radiation performance.
It should be noted that the gap between the first end of the first radiator 20 and the first end of the second radiator 30 may be referred to as a first break, and similarly, the gap between the second end of the first radiator 20 and the third radiator 50 may also be referred to as a second break.
As an optional implementation manner, a first insulating connector is disposed between the first end of the second radiator 30 and the first end of the first radiator 20, and the first insulating connector is fixedly connected to the first end of the second radiator 30 and the first end of the first radiator 20, respectively.
That is to say: the first break may be provided with a first insulating connector, so that since the first insulating connector is provided between the first end of the second radiator 30 and the first end of the first radiator 20, the connection strength between the second radiator 30 and the first radiator 20 may be enhanced, and the insulating property between the second radiator 30 and the first radiator 20 may also be enhanced.
As an optional implementation manner, a second insulating connector is disposed between the third radiator 50 and the second end of the first radiator 20, and the second insulating connector is fixedly connected to the third radiator 50 and the first end of the first radiator 20, respectively.
That is to say: a second insulating connector may be disposed at the second fracture, so that since the second insulating connector is disposed between the third radiator 50 and the second end of the first radiator 20, the connection strength between the third radiator 50 and the first radiator 20 may be enhanced, and the insulating property between the third radiator 50 and the first radiator 20 may also be enhanced.
