Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to an antenna device and an electronic equipment. Background Art

[0002] The antenna of an electronic device is usually arranged in the form of a metal side. During the operation of the antenna, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the feeding part of the antenna is arranged on the upper part of the electronic device, and a traveling wave current (such as Figure 2 As shown by the arrow in the middle, the main radiation pattern of the antenna will be in the direction of phase lag, that is, towards the bottom of the electronic device, resulting in a smaller proportion of radiation above the electronic device, affecting the reception effect of the antenna. That is, for the entire electronic device, the radiation on one side of the electronic device accounts for a smaller proportion than the radiation on the other side of the electronic device.

[0003] In the related art, the problem of the small proportion of radiation from the top of the electronic device can be solved by moving the antenna arrangement position toward the bottom of the electronic device. However, when the user holds the electronic device, the antenna will be blocked, resulting in a decrease in the efficiency of the antenna's signal reception. Alternatively, a resonant device is arranged under the original antenna to suppress the traveling wave current of the antenna toward the bottom. However, the resonant device will occupy the space of the electronic device, affecting the arrangement of other devices in the electronic device, thereby affecting the performance of the electronic device.

[0004] Therefore, how to increase the radiation proportion of the side of the antenna where the radiation proportion is relatively small in the electronic device without changing the existing antenna layout has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The present application aims to provide an antenna device and an electronic device, which can solve the problem in the related art of how to increase the radiation proportion of a side of the electronic device where the radiation proportion is relatively small without changing the existing antenna layout.

[0006] In a first aspect, an embodiment of the present application provides an antenna device for an electronic device, the electronic device comprising a housing and a mainboard disposed in the housing, the housing comprising a top side and a bottom side opposite to the top side, the antenna device comprising:

[0007] A radiator is arranged at the edge of the shell and is located between the top side and the bottom side, and a gap is formed between two ends of the radiator;

[0008] A first feeder is provided on the main board, the distance between the first feeder and the top side is smaller than the distance between the first feeder and the bottom side, and the first feeder is connected to the radiator;

[0009] A resonance component is disposed in the housing, a first end of the resonance component is connected to the mainboard, and a second end of the resonance component extends toward the bottom side;

[0010] Among them, along the direction from the top side to the bottom side, the first feeding part is located between the break and the top side, and the first end of the resonance component is located between the break and the bottom side. When the electronic device is running, the resonance component is used to couple the resonance of the mainboard to generate a resonance current toward the bottom side in the resonance component.

[0011] In a second aspect, an embodiment of the present application provides an electronic device, including a housing; a mainboard disposed in the housing; and an antenna device as in the first aspect.

[0012] The antenna device of the embodiment of the present application is provided with a resonant component, so that during the operation of the electronic device, the resonant component can generate a resonant current toward the bottom side of the shell of the electronic device under the resonance of the coupling mainboard of the electronic device, that is, under the excitation of the resonance generated by the mainboard, and the traveling wave current generated in the radiator toward the bottom side of the shell can be uniformly suppressed through the resonant current, thereby effectively increasing the radiation ratio of the antenna device on the top side of the shell and improving the receiving effect of the antenna device. At the same time, the resonant component utilizes the original mainboard and shell of the electronic device, so there is no need to separately set up a resonant source that can generate resonance, thereby reducing the space occupied by the electronic device and not affecting the arrangement of other devices in the electronic device, thereby achieving an increase in the radiation ratio of the antenna device on the top side of the shell without changing the layout of the existing antenna of the electronic device.

[0039] Combine the following Figures 6 to 19 An antenna device and an electronic device according to embodiments of the present application are described.

[0040] In some embodiments of the present application, an antenna device is provided. Figure 6One of the structural schematic diagrams of the antenna device according to the embodiment of the present application is shown. Figure 6 As shown, the antenna device 100 is used for an electronic device 200, and the electronic device 200 includes a housing 202 and a mainboard 204 arranged in the housing 202, the housing 202 includes a top side and a bottom side opposite to the top side, and the antenna device 100 includes: a radiator 102, the radiator 102 is arranged around the edge of the housing 202, and is located between the top side and the bottom side, and a break 108 is provided between the two ends of the radiator 102, and the break 108 is located between and; a first feeder 104, which is arranged on the mainboard 204, and the distance between the first feeder 104 and the top side is smaller than the distance between the first feeder 104 and the bottom side, and the first feeder 104 is provided on the mainboard 204. The electrical part 104 is connected to the radiator 102; the resonant component 106 is arranged in the shell 202, the first end of the resonant component 106 is connected to the mainboard 204, and the second end of the resonant component 106 extends toward the bottom side; wherein, along the direction from the top side to the bottom side, the first feeding part 104 is located between the break 108 and the top side, and the first end of the resonant component 106 is located between the break 108 and the bottom side. When the electronic device 200 is running, the resonant component 106 is used to couple the resonance of the mainboard 204, that is, the resonant component 106 can generate a resonant current toward the bottom side under the excitation of the resonance generated by the mainboard 204.

[0041] In the embodiment of the present application, the antenna device 100 can be used in an electronic device 200, and the electronic device 200 includes a housing 202 and a mainboard 204 disposed in the housing 202, and the housing 202 includes a top side and a bottom side opposite to the top side. It should be noted that the top side of the housing 202 may be the top of the electronic device 200, and correspondingly, the bottom side of the housing 202 is the bottom of the electronic device 200. That is, when the user holds the electronic device 200, the top side is the side facing upward, and the bottom side is the side facing the ground.

[0042] Further, the antenna device 100 includes a radiator 102, which is arranged at the edge of the housing 202 of the electronic device 200 and is located between the top side and the bottom side, that is, the radiator 102 can be located at the side edge of the electronic device 200. The radiator 102 can be used to receive and transmit signals. Specifically, there is a break 108 between the two ends of the radiator 102, that is, there is a certain distance between the two ends of the radiator 102. In this way, the electronic device 200 can receive and transmit signals through the two ends of the radiator 102 during operation. Among them, the break 108 is located between the top side of the housing 202 and the bottom side of the housing 202, that is, compared with the top and bottom of the electronic device 200, the break 108 can be located on one side of the electronic device 200.

[0043] Furthermore, the antenna device 100 further includes a first feeder 104, which is disposed on the mainboard 204 of the electronic device 200. At the same time, the first feeder 104 is also connected to the radiator 102, that is, the radiator 102 is connected to the feed source of the mainboard 204 through the first feeder 104, thereby realizing the signal transmission function of the radiator 102. At the same time, the distance between the first feeder 104 and the top side is smaller than the distance between the first feeder 104 and the bottom side, that is, the first feeder 104 is located at a position close to the top side of the electronic device 200, that is, located at the upper half of the electronic device 200.

[0044] Furthermore, the antenna device 100 further includes a resonant component 106, which is disposed in the housing 202, and a first end of the resonant component 106 is connected to the mainboard 204, and a second end of the resonant component 106 extends toward the bottom side of the housing 202. During the operation of the electronic device 200, the resonant component 106 can couple the resonance of the mainboard 204, thereby generating a resonant current on the resonant component 106, and the resonant current flows from the first end of the resonant component 106 to the second end of the resonant component 106, that is, the resonant current generated by the resonant component 106 moves toward the bottom side of the electronic device 200.

[0045] It can be understood that during the operation of the electronic device 200, the first power feeder 104 is arranged at a position close to the top side of the electronic device 200, and when the radiator 102 receives and transmits signals, a traveling wave current is generated in the direction of the bottom side of the housing 202, thereby causing the main radiation direction of the radiator 102 to be toward the bottom side of the housing 202. At this time, by providing the resonant component 106, a resonant current toward the bottom side of the electronic device 200 can be generated during the operation of the electronic device 200, and the resonant component 106 is arranged between the slit 108 and the bottom side, that is, arranged at a position close to the bottom side of the housing 202 of the first power feeder 104, so that the resonant current generated by the resonant component 106 can suppress the traveling wave current generated in the radiator 102, thereby causing the traveling wave current generated in the radiator 102 to move toward the top side of the housing 202, which can effectively increase the radiation proportion of the antenna device 100 on the top side of the housing 202 and improve the receiving effect of the antenna device 100. In addition, it should be noted that the frequency of the resonant current generated in the resonant component 106 can be greater than or equal to the frequency of the signal generated by the radiator 102, thereby improving the suppression effect of the resonant current on the traveling wave current, thereby effectively increasing the radiation ratio of the antenna device 100 on the top side of the shell 202.

[0046] Furthermore, one end of the resonant component 106 is connected to the mainboard 204 of the electronic device 200, and the resonant component 106 is disposed on the housing 202 of the electronic device 200. That is, the resonant component 106 can utilize the resonance generated by the mainboard 204 of the electronic device 200 during operation, that is, the resonance generated by coupling the mainboard 204, to generate a resonant current, thereby achieving an increase in the radiation ratio of the antenna device 100 on the top side of the housing 202. That is, the resonant component 106 utilizes the original structural components of the electronic device 200, and there is no need to separately set up a resonant source capable of generating resonance, thereby reducing the space occupied by the electronic device 200, and does not affect the arrangement of other components in the electronic device 200, and can achieve an increase in the radiation ratio of the antenna device 100 on the top side of the housing 202 without changing the layout of the existing antenna of the electronic device 200.

[0047] The antenna device 100 of the embodiment of the present application is provided with a resonant component 106, so that during the operation of the electronic device 200, the resonant component 106 can couple the resonance of the mainboard 204 of the electronic device 200, that is, under the excitation of the resonance generated by the mainboard 204, a resonant current toward the bottom side of the housing 202 of the electronic device 200 is generated on the resonant component 106, and the traveling wave current generated in the radiator 102 toward the bottom side of the housing 202 can be suppressed by the resonant current, thereby effectively improving the radiation ratio of the antenna device 100 on the top side of the housing 202 and improving the receiving effect of the antenna device 100. At the same time, the resonant component 106 utilizes the original mainboard 204 and housing 202 of the electronic device 200, so there is no need to separately set up a resonant source that can generate resonance, thereby reducing the space occupied by the electronic device 200 and not affecting the arrangement of other components in the electronic device 200. Therefore, it is possible to improve the radiation ratio of the antenna device 100 on the top side of the housing 202 without changing the layout of the existing antenna of the electronic device 200.

[0048] In addition, it should be noted that in the related art, in order to improve other performances of the antenna device 100, that is, in addition to improving the radiation ratio of the antenna device 100 on the top side of the shell 202, some electronic devices 200 are provided with parasitic devices. During the operation of the electronic device 200, the parasitic device can generate a parasitic current toward the top side of the shell 202. However, since the direction of the parasitic current is the top side of the shell 202, the parasitic current does not suppress the traveling wave current in the radiator 102 toward the bottom side of the shell 202, and thus cannot improve the radiation ratio of the antenna device 100 on the top side of the shell 202. However, the resonant current generated by the resonant component 106 in the present application is toward the bottom side of the shell 202, so it can suppress the traveling wave current generated in the radiator 102 toward the bottom side of the shell 202, thereby improving the radiation ratio of the antenna device 100 on the top side of the shell 202.

[0049] Specifically, the antenna device 100 may be a WIFI (Wireless Fidelity) antenna device.

[0050] In some embodiments of the present application, Figure 7 The second structural schematic diagram of the antenna device according to the embodiment of the present application is shown as follows: Figure 7 As shown, the resonance component 106 includes: a connector 110, which is arranged on the mainboard 204; a coupling component 112, one end of the coupling component 112 is connected to the connector 110, and the other end of the coupling component 112 is arranged on the shell 202 and extends toward the bottom side; wherein, when the electronic device 200 is running, the coupling component 112 is used to couple the resonance generated by the mainboard 204 to generate a resonance current toward the bottom side.

[0051] In the embodiment of the present application, the resonance component 106 includes a connector 110 , which can be disposed on a mainboard 204 of the electronic device 200 , so as to transmit the resonance generated by the mainboard 204 during the operation of the electronic device 200 .

[0052] Further, the resonant component 106 further includes a coupling component 112, wherein one end of the coupling component 112 is connected to the connector 110, and the other end of the coupling component 112 is disposed on the housing 202, and the other end of the coupling component 112 extends toward the bottom side of the housing 202. It should be noted that the housing 202 may include a frame and a back cover, and the coupling component 112 may be disposed on the frame or on the back cover.

[0053] By providing the coupling component 112, during the operation of the electronic device 200, the resonance generated by the mainboard 204 can be coupled to the second end of the coupling component 112 through the coupling connection between the first end of the coupling component 112 and the second end of the coupling component 112. That is, under the excitation of the resonance generated by the mainboard 204, a resonant current is generated in the coupling component 112, and the second end of the coupling component 112 extends toward the bottom side of the housing 202, so that a resonant current toward the bottom side of the housing 202 can be generated on the second end of the coupling component 112, and then the traveling wave current generated in the radiator 102 toward the second end of the housing 202 is suppressed through the resonant current, thereby increasing the radiation ratio of the antenna device 100 on the top side of the housing 202 and improving the receiving effect of the antenna device 100.

[0054] In some embodiments of the present application, Figure 8 The third structural diagram of the antenna device according to the embodiment of the present application is shown as follows: Figure 8 As shown, the coupling assembly 112 includes: a first conductive plate 114 connected to the connector 110; a second conductive plate 116 disposed in the housing 202 and coupled to the first conductive plate 114, and the second conductive plate 116 extends toward the bottom side.

[0055] In the embodiment of the present application, the coupling component 112 includes a first conductive plate 114 and a second conductive plate 116, and the first conductive plate 114 and the second conductive plate 116 are coupled to each other. The first conductive plate can generate a resonant current under the excitation of the resonance generated by the main board 204, and then, through the coupling connection between the first conductive plate 114 and the second conductive plate 116, the resonant current can be coupled to the second conductive plate 116.

[0056] Furthermore, the second conductive plate 116 extends toward the bottom side of the housing 202, so that a resonant current flowing toward the bottom side of the housing 202 can be generated on the second conductive plate 116. This suppresses the traveling wave current generated in the radiator 102 and flowing toward the bottom side of the housing 202, thereby increasing the radiation ratio of the antenna device 100 at the top side of the housing 202.

[0057] In addition, the shell 202 may include a frame and a back cover, and the second conductive plate 116 is arranged on the back cover of the shell 202, so that the second conductive plate 116 only needs to occupy a very small space in the shell 202 and does not affect the arrangement of other components in the electronic device 200. Therefore, it is possible to increase the radiation ratio of the antenna device 100 on the top side of the shell 202 without changing the layout of the existing antenna of the electronic device 200.

[0058] It should be noted that, in the direction from the top side to the bottom side, the length of the second conductive plate 116 is set according to the frequency of the electromagnetic waves emitted by the radiator 102 so that the frequency of the resonant current generated by the second conductive plate 116 is greater than or equal to the frequency of the electromagnetic waves emitted by the radiator 102 .

[0059] Specifically, in the direction from the top side of the housing 202 to the bottom side of the housing 202, the length of the second conductive plate 116 can be set according to the frequency of the electromagnetic wave emitted by the radiator 102, so as to ensure that the resonant current generated on the second conductive plate 116 toward the bottom side of the housing 202 can effectively suppress the traveling wave current in the radiator 102 toward the bottom side of the housing 202.

[0060] Specifically, by setting the length of the second conductive plate 116, during the operation of the electronic device 200, the frequency of the resonant current generated in the second conductive plate 116 is greater than or equal to the frequency of the electromagnetic wave generated by the radiator 102, thereby ensuring that the resonant current generated by the second conductive plate 116 toward the bottom side of the shell 202 can effectively suppress the traveling wave current in the radiator 102 toward the bottom side of the shell 202, thereby achieving an increase in the radiation ratio of the antenna device 100 on the top side of the shell 202.

[0061] Specifically, taking WIFI2.4G as an example, by setting the length of the second conductive plate 116 so that the frequency of the harmonic current generated in the second conductive plate 116 reaches the frequency of the electromagnetic waves generated by WIFI2.4G, or is slightly higher than the frequency of the electromagnetic waves generated by WIFI2.4G, the traveling wave current in the radiator 102 toward the bottom side of the shell 202 can be suppressed.

[0062] In some embodiments of the present application, along a direction perpendicular to the top side to the bottom side, an area of ​​an overlapping portion of the first conductive plate 114 and the second conductive plate 116 is larger than the first area.

[0063] In the embodiment of the present application, the area of ​​the overlapping portion of the first conductive plate 114 and the second conductive plate 116 can be set to ensure the resonance amount generated by the mainboard 204 of the electronic device 200 to which the second conductive plate 116 can be coupled, and then to ensure the size of the resonant current generated by the second conductive plate 116, so as to ensure that the resonant current generated on the second conductive plate 116 toward the bottom side of the shell 202 can effectively suppress the traveling wave current in the radiator 102 toward the bottom side of the shell 202.

[0064] Specifically, in the direction perpendicular to the top side to the bottom side, the area of ​​the overlapped portion of the first conductive plate 114 and the second conductive plate 116 is larger than the first area. The first area can be specifically set according to the frequency of the electromagnetic waves emitted by the electronic device 200 and the antenna device 100.

[0065] For example, for WIFI 2.4G, the size of the first conductive plate 114 can be set to 2mm×2mm, and the entire area of ​​the first conductive plate 114 overlaps with the second conductive plate 116. In this case, the size of the second conductive plate 116 can be set to 2mm×14mm, that is, the area of ​​the overlapped portion of the first conductive plate 114 and the second conductive plate 116, that is, the first area is 4mm 2 Specifically, the first area can be set according to the frequency of the electromagnetic wave radiated by the antenna device. For example, the value range of the first area can be 1mm 2 Up to 10mm 2 By setting the size of the first conductive plate 114 and the second conductive plate 116, it is possible to ensure the resonance amount coupled to the second conductive plate 116, and it is also possible to ensure that the frequency of the harmonic current generated on the second conductive plate 116 can reach the frequency of the electromagnetic wave generated by WIFI2.4G, so as to suppress the traveling wave current in the radiator 102 toward the bottom side of the housing 202.

[0066] In some embodiments of the present application, Figure 8 As shown, the connecting member 110 includes a metal spring 118 , the metal spring 118 is disposed on the mainboard 204 , and the coupling component 112 is electrically connected to the metal spring 118 .

[0067] In the embodiment of the present application, the connecting member 110 may be a metal spring 118. By setting the metal spring 118 on the mainboard 204 and connecting the coupling component 112 to the metal spring 118, a resonant current can be generated on the coupling component 112 under the excitation of the resonance generated by the mainboard 204, so as to couple the resonance generated by the mainboard 204.

[0068] Specifically, the metal spring 118 is set on the mainboard 204, the first conductive plate 114 of the coupling component 112 is connected to the metal spring 118, and the second conductive plate 116 of the coupling component 112 is set on the shell 202 of the electronic device 200, thereby coupling the resonance generated by the mainboard 204 to the second conductive plate 116 to generate a resonant current on the second conductive plate 116.

[0069] By configuring the connector 110 as a metal spring 118 , the cost of the resonant component 106 can be effectively reduced, thereby effectively reducing the cost of the electronic device 200 while increasing the radiation ratio of the antenna device 100 on the top side of the housing 202 .

[0070] For example, Fig. 9 Shows Figure 8 Distribution diagram of traveling wave current during operation of the antenna device; Fig.10Shows Figure 8 A scattering parameter curve diagram of the antenna device during operation of the antenna device; Fig.11 Shows Figure 8 The antenna efficiency curve diagram of the antenna device during the operation of the antenna device; Fig.12 Shows Figure 8 Schematic diagram of the radiation ratio of the antenna device during the operation of the antenna device; Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, Figure 2 , Figure 3 , Figure 4 and Figure 5 By comparison, it can be seen that compared with the electronic device in the related art, the antenna device 100 provided in the embodiment of the present application, the traveling wave current (such as Fig. 9 The traveling wave current (indicated by the arrow in the middle) is effectively suppressed, and most of the traveling wave current no longer flows toward the bottom side of the housing 202, thereby effectively improving the radiation ratio of the antenna device 100 in the direction of the top side.
