Description

Technical Field

[0001] This disclosure relates to the field of antenna technology, and in particular to an antenna structure and terminal device. Background Technology

[0002] With the rapid development of communication technology, the number of antennas in terminal devices is constantly increasing. Due to the limited space for device layout in the pursuit of thinner and lighter terminal devices, the integration of antennas in terminal devices is becoming increasingly high, and the conductive frame of the terminal device is often used as the antenna. However, isolating the conductive frame with a partition strip will affect the antenna performance of the conductive frame. Therefore, how to improve antenna performance while isolating the conductive frame has become an urgent problem to be solved. Utility Model Content

[0003] To overcome the problems existing in related technologies, this disclosure provides an antenna structure and terminal device that can improve antenna performance.

[0004] According to a first aspect of the present disclosure, an antenna structure is provided, including: a conductive frame, an impedance component, a first connector, and a second connector;

[0005] The conductive frame is separated to form two frame regions;

[0006] The first connector is connected to one of the frame regions and the impedance component, respectively;

[0007] The second connector is connected to another of the said frame regions and the impedance component, respectively;

[0008] The impedance component is positioned near the partition of the conductive frame and is used to tune the antenna signal formed by the conductive frame.

[0009] In this embodiment of the disclosure, the two separated frame areas can be connected by two connecting posts and an impedance component, thereby enabling tuning through the impedance component to improve antenna performance and reduce the impact of the separation of the conductive frame on antenna performance.

[0010] In some embodiments, the antenna structure further includes an antenna board;

[0011] The impedance component is disposed on the antenna board;

[0012] The first connector has a first part and a second part, the first part being connected to the antenna board and the second part being connected to a frame area;

[0013] The second connector has a third part and a fourth part, the third part being connected to the antenna board and the fourth part being connected to another of the frame areas.

[0014] In this embodiment, by setting an antenna board, the first connector and the second connector can be connected to the impedance component respectively, thereby enabling tuning through the impedance component to improve antenna performance. Furthermore, by setting an antenna board to connect the two connectors and the impedance component, the antenna setup becomes more flexible and suitable for conductive frames that are isolated at different locations.

[0015] In some embodiments, the first part, the third part, and the impedance component are all soldered to different locations on the same side of the antenna board.

[0016] In this embodiment of the disclosure, by welding the first part, the third part, and the impedance component to the antenna board, it is possible to more easily assemble the first connector and the second connector onto the conductive frame.

[0017] In some embodiments, the impedance component is disposed at the center of the antenna board;

[0018] The first connector and the second connector are symmetrically arranged on both sides of the impedance component with the impedance component as the center of symmetry.

[0019] In this embodiment of the present disclosure, the first connector, the second connector, and the impedance component are symmetrically arranged on the antenna board, which enables the antenna board assembly formed based on the first connector, the second connector, the impedance component, and the antenna board to be a standard part. During installation, no specific assembly method is required, which makes the assembly method more flexible.

[0020] In some embodiments, both the second portion and the fourth portion are exposed outside the antenna board and connected to the conductive frame and the middle frame for supporting the antenna board.

[0021] In this embodiment, the first and third parts are connected to the antenna board, while the second and fourth parts are not in contact with the antenna board but are used to connect the conductive frame and the middle frame, which enables a more reliable installation of the antenna structure.

[0022] In some embodiments, a first welding position is formed on the inner side of one of the frame regions; a second welding position is formed on the inner side of the other frame region;

[0023] The second part is soldered to the first soldering position on the side facing the conductive frame;

[0024] The fourth part is welded to the second welding position on the side facing the conductive frame.

[0025] In this embodiment of the disclosure, by setting a first welding position and a second welding position, the first connector and the second connector can be better welded to the conductive frame.

[0026] In some embodiments, the side of the second portion facing away from the conductive frame and the side of the fourth portion facing away from the conductive frame are both adhered to the middle frame.

[0027] In this embodiment of the present disclosure, after the second part is welded to the first welding position and the fourth part is welded to the second welding position, the second part and the fourth part are respectively glued to the middle frame, which can further increase the assembly strength and improve the reliability of the antenna structure assembly.

[0028] In some embodiments, the difference between the area of ​​the second portion and the area of ​​the first portion is less than a first preset difference threshold.

[0029] And / or,

[0030] The difference between the area of ​​the fourth part and the area of ​​the third part is less than the second preset difference threshold.

[0031] In this embodiment of the disclosure, by setting the difference between the area of ​​the first part and the area of ​​the second part to be less than a first preset difference threshold, the first part and the second part can be kept in balance when welded separately, thereby making the first connector easier to assemble.

[0032] In some embodiments, both the first connector and the second connector include a metal sheet;

[0033] And / or, the impedance component includes at least a capacitive element.

[0034] In this embodiment, by setting two metal sheets and an impedance component, the two separated frame regions can be connected. This not only enables tuning via the impedance component to improve antenna performance but also reduces stacking space and improves the space utilization of the antenna structure. Furthermore, by changing the capacitance value of the capacitor element, the antenna structure can be tuned, thereby improving antenna performance.

[0035] In some embodiments, the impedance component is coated with a protective adhesive that surrounds the impedance component.

[0036] In this embodiment, coating the impedance component with protective adhesive can better protect the impedance component and extend its service life; it can also reduce the likelihood of the impedance component falling off the antenna board assembly, making transportation more convenient.

[0037] According to a second aspect of the present disclosure, a terminal device is provided, comprising: an antenna structure as described in the first aspect above.

[0038] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0039] In this embodiment, an impedance component is disposed at a partition position near the conductive frame. A first connector is provided to connect one partitioned frame area and the impedance component, and a second connector is provided to connect the other partitioned frame area and the impedance component. In other words, the two partitioned frame areas in this embodiment can be connected by two connecting posts and the impedance component, thereby enabling tuning via the impedance component to improve antenna performance and reduce the impact of the conductive frame partition on antenna performance.

[0050] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0051] This disclosure provides an antenna structure suitable for scenarios where the frame antenna is isolated. By incorporating this antenna structure into the terminal device, the impact of the isolated conductive frame on antenna performance can be reduced, thereby improving antenna performance.

[0052] like Figures 1 to 7 As shown, the antenna structure 10 includes: a conductive frame 11, a first connector 12, a second connector 13, and an impedance component 14;

[0053] The conductive frame 11 is separated to form two frame regions 110;

[0054] The first connector 12 is connected to one of the frame regions 110 and the impedance component 14 respectively;

[0055] The second connector 13 is connected to another of the frame regions 110 and the impedance component 14, respectively;

[0056] The impedance component 14 is positioned near the partition position A of the conductive frame 11 and is used to tune the antenna signal formed by the conductive frame 11.

[0057] In this embodiment of the disclosure, the antenna module is applied in a terminal device to transmit and receive radio waves to transmit and exchange wireless signals. The terminal device includes: smartphones, tablets, laptops, wearable devices, or personal digital assistants (PDAs), etc. Wearable devices include, but are not limited to, smartwatches or smart bracelets.

[0058] The aforementioned conductive frame can be the exposed edge frame of the terminal device. Here, the conductive frame of this embodiment can be reused as an antenna, thereby reducing the space occupied by the antenna structure and improving integration.

[0059] The aforementioned conductive frame can be divided into two frame regions by a partition strip. The conductive frame separated by the partition strip can be used as a radiator for transmitting and receiving wireless signals in an antenna structure.

[0060] It should be noted that the radiator of the antenna structure for transmitting and receiving wireless signals can operate in cellular mobile antenna bands, Wi-Fi bands, millimeter-wave antenna bands, Bluetooth antenna bands, satellite antenna bands, and / or ultra-wideband antenna bands, etc.

[0061] Here, the partition strip can divide the conductive frame in a direction perpendicular to the extension direction of the conductive frame. The partition strip can be an insulating component, which may include plastic or rubber components, etc., and the embodiments disclosed herein are not limited thereto.

[0062] The first connector is connected to one frame area and an impedance component, respectively. The second connector is connected to another frame area and an impedance component, respectively. In other words, the two separated frame areas can be connected through the first connector, the second connector, and the impedance component, thereby enabling tuning via the impedance component to improve antenna performance.

[0063] It should be noted that both the first and second connectors are conductive.

[0064] In some embodiments, both the first connector and the second connector may include conductive connecting posts. That is, the two separated frame areas can be connected by two conductive connecting posts and an impedance component.

[0065] In some embodiments, both the first connector 12 and the second connector 13 may include a metal sheet.

[0066] Here, the metal sheet can use its own sheet-like surface to connect the frame area and the impedance component, or it can use its two different ends to connect the frame area and the impedance component. This disclosure does not limit this.

[0067] It is understood that, in this embodiment of the present disclosure, by setting two metal sheets and an impedance component, the two separated frame areas can be connected. This not only enables tuning through the impedance component to improve antenna performance, but also reduces the stacking space and improves the space utilization of the antenna structure.

[0068] In this embodiment of the disclosure, the impedance component, the first connector, and the second connector can all be directly disposed on the motherboard, so that the impedance component is connected to the first connector and the second connector respectively through the motherboard; alternatively, an antenna board can be disposed, and the impedance component, the first connector, and the second connector can all be disposed on the antenna board, so that the impedance component is connected to the first connector and the second connector respectively through the antenna board.

[0069] It should be noted that the motherboard is used to integrate all key hardware components (such as communication components, processors, and power supply components) to achieve functions such as data transmission, signal processing, and power management. The antenna board is used as a circuit board responsible for wireless signal tuning to enable the transmission and reception of wireless signals through the antenna structure.

[0070] Here, both the main board and the antenna board are printed circuit boards, but the main board is smaller than the antenna board. The main board can be positioned in the center of the electronic device with the antenna structure or near the battery. The antenna board can be positioned on the side of the electronic device's frame facing the conductive border.

[0071] In this embodiment of the disclosure, an impedance component is disposed at a partition position near the conductive frame to tune the antenna signal formed by the conductive frame.

[0072] It should be noted that the partition position of the impedance component near the conductive frame may include: the impedance component being aligned with the partition position; or the impedance component being offset from the partition position. This disclosure does not limit this.

[0073] In this embodiment of the disclosure, different impedance values ​​of the impedance components will affect the antenna performance when the conductive frame is used as an antenna.

[0074] It should be noted that isolating the conductive frame affects the current path on the conductive frame. By adjusting the impedance component, the antenna signal formed by the conductive frame can be tuned, thereby changing the length of the antenna current path. Thus, by changing the impedance value of the impedance component, the length of the antenna current path can be lengthened or shortened, optimizing the antenna performance of the antenna structure.

[0075] In this embodiment of the disclosure, the impedance component may be composed of multiple electrical components or a single electrical component, and this embodiment of the disclosure does not limit this.

[0076] In some embodiments, such as Figure 2 As shown, impedance component 14 includes at least a capacitor element.

[0077] In this embodiment of the disclosure, the capacitor element may include an element with a fixed capacitance value, or an element with a variable capacitance value; this embodiment of the disclosure does not limit this.

[0078] It should be noted that when designing an antenna structure, appropriate impedance components with suitable capacitance values ​​can be selected based on factors such as the transmit and receive frequency bands and impedance matching of the antenna structure.

[0079] In this embodiment of the disclosure, the antenna structure can be tuned by changing the capacitance value of the capacitor element, thereby improving the antenna performance.

[0080] Here, the impedance component may further include inductive elements and / or resistive elements, that is, the impedance component is composed of capacitive elements, inductive elements, and / or resistive elements. Among them, the inductive element may be an element with a fixed inductance value or a variable inductance value, and the resistive element may be an element with a fixed resistance value or a variable resistance value; the embodiments disclosed herein do not impose any limitations on this.

[0081] In this embodiment, an impedance component is disposed at a partition position near the conductive frame. A first connector is provided to connect one partitioned frame area and the impedance component, and a second connector is provided to connect the other partitioned frame area and the impedance component. In other words, the two partitioned frame areas in this embodiment can be connected by two connecting posts and the impedance component, thereby enabling tuning via the impedance component to improve antenna performance and reduce the impact of the conductive frame partition on antenna performance.

[0082] In some embodiments, such as Figures 1 to 6 As shown, the antenna structure 10 also includes an antenna board 15;

[0083] The impedance component 14 is disposed on the antenna board 15;

[0084] The first connector 12 has a first part 121 and a second part 122, the first part 121 being connected to the antenna board 15, and the second part 122 being connected to a frame area 110;

[0085] The second connector 13 has a third part 131 and a fourth part 132, the third part 131 being connected to the antenna board 15, and the fourth part 132 being connected to another of the frame areas 110.

[0086] In this embodiment, the antenna board is a small board used to carry the impedance component, the first connector, and the second connector. The antenna board can be disposed at any position on the middle frame. The middle frame can be used to carry both the antenna board and the main board.

[0087] It should be noted that, in order to reduce the space occupied by the antenna structure, a groove can be formed by recessing the middle frame on the side facing the conductive frame, and the antenna board can be placed in this groove. Here, the groove can be aligned with the partition position. Of course, the groove can also be set on either side aligned with the partition position, and this embodiment of the present disclosure is not limited to this.

[0088] In this embodiment of the disclosure, the first part and the second part may be two surfaces of the first connector that are disposed opposite to each other. That is, the first connector can be connected to the antenna board and a frame area respectively through the two surfaces that are disposed opposite to each other.

[0089] Of course, the first connector can be divided into a first part and a second part, and the first part and the second part can be connected to form an integral first connector. That is to say, the first connector can be connected to an antenna board and a frame area respectively through different components.

[0090] For example, the first connector is a connecting piece, which can be folded in half on the sheet-like surface, with the folded half of the connector serving as the first part and the folded other half serving as the second part.

[0091] In this embodiment of the disclosure, the third and fourth portions may be two surfaces of the second connector that are disposed opposite to each other. That is, the second connector can be connected to the antenna board and another frame area respectively through the two surfaces that are disposed opposite to each other.

[0092] Of course, the second connector can be divided into a third part and a fourth part, and the connection of the third part and the fourth part can form an integral second connector. That is to say, the second connector can be connected to the antenna board and another frame area respectively through different components.

[0093] For example, the second connector is a connecting piece, which can be folded in half on its sheet-like surface. The folded half of the connector is used as the third part, and the folded other half is used as the fourth part.

[0094] In this embodiment of the disclosure, when the second part and the fourth part are connected to the conductive frame, they can be connected to the conductive frame by welding or abutting, and this embodiment of the disclosure does not limit this.

[0095] It is understood that, in this embodiment of the disclosure, by setting an antenna board, the first connector and the second connector can be connected to the impedance component respectively, thereby enabling tuning through the impedance component to improve antenna performance. Furthermore, by setting an antenna board to connect the two connectors and the impedance component, the application scenarios of the antenna can be made more flexible, suitable for conductive frames that are isolated at different locations.

[0096] It has been verified that by setting the first connector, the second connector, and the impedance component across the partition on the antenna board, the antenna performance can be improved by at least 2dB.

[0097] In some embodiments, such as Figures 1 to 6 As shown, the first part 121, the third part 131, and the impedance component 14 are all soldered to different positions on the same side of the antenna board 15.

[0098] In this embodiment of the disclosure, the first part, the third part, and the impedance component are soldered to different positions on the same side of the antenna board using surface mount technology to form an antenna board assembly.

[0099] It should be noted that in the process of forming the antenna board assembly, the impedance component can be first soldered onto the antenna board using surface mount technology, and then the first connector and the second connector can be soldered onto the antenna board simultaneously using surface mount technology, thereby assembling the antenna board assembly.

[0100] Here, to protect the impedance components on the antenna board, a protective adhesive can be applied to the antenna board. In some embodiments, such as... Figure 1 and Figure 2 As shown, the impedance component 14 is coated with a protective adhesive 16, which surrounds the impedance component 14.

[0101] In this embodiment of the disclosure, the protective adhesive includes, but is not limited to, epoxy resin adhesive, silicone adhesive, polyurethane adhesive, UV adhesive, thermally conductive silicone adhesive, silicone sealant, hot melt adhesive, etc.

[0102] It should be noted that before forming the antenna board assembly, after welding the first and second connectors, protective adhesive can be applied to the impedance components, thus completing the assembly of the antenna board assembly.

[0103] It is understood that, in this embodiment of the present disclosure, coating the impedance component with protective adhesive can not only better protect the impedance component and extend its service life, but also reduce the likelihood of the impedance component falling off the antenna board assembly, making transportation more convenient.

[0104] In this embodiment of the present disclosure, welding the first part, the third part, and the impedance component to different positions on the same side of the antenna board may include: the first part, the third part, and the impedance component being spaced apart along the length direction of the conductive frame on the same side of the antenna board; it may also include: the impedance component being welded to the center of the antenna board, and the first part and the third part being disposed on adjacent sides of the impedance component.

[0105] It is understood that, in this embodiment of the present disclosure, by welding the first part, the third part, and the impedance component to the antenna board, it is possible to more easily assemble the first connector and the second connector to the conductive frame.

[0106] In some embodiments, the impedance component 14 is disposed at the center of the antenna board 15; the first connector 12 and the second connector 13 are symmetrically disposed on both sides of the impedance component 14 with the impedance component 14 as the center of symmetry.

[0107] In this embodiment, the first connector and the second connector are identical. Here, the first connector and the second connector can be devices of the same size and material. For example, both the first connector and the second connector can be copper sheets.

[0108] In this embodiment of the disclosure, during assembly, the impedance component can be aligned with the partition position, that is, the center of the antenna board is aligned with the partition position.

[0109] It is understood that in the embodiments of this disclosure, the first connector, the second connector, and the impedance component are symmetrically arranged on the antenna board, which enables the antenna board assembly formed based on the first connector, the second connector, the impedance component, and the antenna board to be a standard part. During installation, it does not require a specific assembly method, which makes the assembly method more flexible.

[0110] In some embodiments, such as Figures 1 to 5 As shown, the second part 122 and the fourth part 132 are both exposed outside the antenna board 15 and are connected to the conductive frame 11 and the middle frame 20 for supporting the antenna board.

[0111] In this embodiment of the disclosure, both the second part and the fourth part are exposed outside the antenna board. This can be understood as follows: the first part of the first connector is connected to the antenna board, and the second part is not in contact with the antenna board; the third part of the second connector is connected to the antenna board, and the fourth part is not in contact with the antenna board.

[0112] In other words, neither the first connector nor the second connector in the embodiments of this disclosure are completely installed in the antenna board, but are partially installed in the antenna board.

[0113] In this embodiment of the disclosure, the first part and the second part may be two parts of the first connector with the same or different areas; the third part and the fourth part may be two parts of the second connector with the same or different areas, and this embodiment of the disclosure does not limit this.

[0114] For example, if the first connector is a metal sheet such as a copper sheet, three-quarters of the copper sheet can be set as the first part and one-quarter of the copper sheet as the second part, that is, the smaller copper sheet part is exposed outside the antenna board.

[0115] For example, if the second connector is a copper sheet, one-quarter of the copper sheet can be set as the third part, and three-quarters of the copper sheet can be set as the fourth part, that is, the larger copper sheet part is exposed outside the antenna board.

[0116] It is understood that in this embodiment of the present disclosure, the first part and the third part are connected to the antenna board, while the second part and the fourth part are not in contact with the antenna board, but are used to connect the conductive frame and the middle frame, which enables a more reliable installation of the antenna structure.

[0117] In some embodiments, such as Figures 1 to 5 As shown, a first welding position B is formed on the inner side of one of the frame regions 110; a second welding position C is formed on the inner side of the other frame region 110.

[0118] The second part 122 is welded to the first welding position B on the side facing the conductive frame 11;

[0119] The fourth part 132 is welded to the second welding position C on the side facing the conductive frame 11.

[0120] In this embodiment of the disclosure, the two separated frame regions each have an outer side facing outwards from the terminal device and an inner side facing inwards from the terminal device.

[0121] It should be noted that the aforementioned first welding position can be reserved at any location on the inner side of a frame area. Here, in order to achieve better welding of the two devices, the second part can be aligned with the first welding position after the antenna board assembly is installed.

[0122] The aforementioned second welding position can be reserved at any location on the inner side of another frame area. Here, to achieve better welding of the two devices, the fourth part can be aligned with the second welding position after the antenna board assembly is installed.

[0123] Here, the distance from the first welding position to the second welding position can be set to be equal to the distance from the second part to the fourth part, thereby achieving better welding.

[0124] In this embodiment of the present disclosure, a conductive frame having a first welding position and a second welding position and an antenna board assembly can be assembled together using a fixture. Then, the second part of the antenna board is connected to the first welding position and the fourth part of the antenna board is connected to the second welding position by laser spot welding.

[0125] For example, such as Figures 4 to 6 As shown, 3*3 solder joints 18 are provided in both the second part 122 and the fourth part 132 to enable the second part 122 to be soldered to the first soldering position B and the fourth part 132 to be soldered to the second soldering position C.

[0126] It is understood that, in the embodiments of this disclosure, by setting the first welding position and the second welding position, the first connector and the second connector can be better welded to the conductive frame.

[0127] In some embodiments, the second portion 122 on the side opposite to the conductive frame 11 and the fourth portion 132 on the side opposite to the conductive frame 11 are both adhered to the middle frame 20.

[0128] In this embodiment of the disclosure, the conductive border can be formed into a ring or a semi-ring and surround the middle frame.

[0129] It should be noted that, in addition to supporting the antenna board, the middle frame can also support other components such as the motherboard or battery, and this disclosure does not limit this.

[0130] Here, after connecting the second part of the antenna board to the first welding position and the fourth part of the antenna board to the second welding position by laser spot welding, the present embodiment can apply adhesive to both the side of the second part away from the conductive frame and the side of the fourth part away from the conductive frame, and then bond the second part and the fourth part to the middle frame.

[0131] Of course, in this embodiment of the present disclosure, adhesive can also be applied to the second part, the fourth part and the middle frame, and the second part and the fourth part can be bonded to the middle frame.

[0132] For example, such as Figure 3 As shown, the second part 122 and the fourth part 132 are bonded to the middle frame 20 with glue 17.

[0133] In this embodiment of the disclosure, when the antenna board is accommodated in the groove of the middle frame, the side of the second part away from the conductive frame and the side of the fourth part away from the conductive frame are both bonded to the bottom of the groove to achieve a more stable assembly of the antenna board assembly.

[0134] It is understood that, in this embodiment of the present disclosure, after the second part is welded to the first welding position and the fourth part is welded to the second welding position, the second part and the fourth part are respectively glued to the middle frame, which can further increase the assembly strength and improve the reliability of the antenna structure assembly.

[0135] In some embodiments, such as Figure 2 As shown, the difference between the area of ​​the second part 122 and the area of ​​the first part 121 is less than a first preset difference threshold.

[0136] And / or,

[0137] The difference between the area of ​​the fourth part 132 and the area of ​​the third part 131 is less than the second preset difference threshold.

[0138] In this embodiment of the disclosure, when the first connector is a metal sheet, the difference between the sheet-like area of ​​the first portion and the sheet-like area of ​​the second portion of the metal sheet is less than a first preset difference threshold. That is, the area difference between the first portion and the second portion should be reduced. For example, the sheet-like areas of the first portion and the second portion can be set to be equal.

[0139] It should be noted that when the difference between the two parts of the first connector is a differential value, the first preset difference threshold is a first preset difference threshold. When the difference between the two parts of the first connector is a ratio, the first preset difference threshold is a first preset ratio threshold.

[0140] In this embodiment of the disclosure, when the second connector is a metal sheet, the difference between the sheet-like area of ​​the third part and the sheet-like area of ​​the fourth part of the metal sheet is less than a second preset difference threshold. That is, the area difference between the third and fourth parts should be reduced. For example, the sheet-like areas of the third part and the fourth part can be set to be equal.

[0141] It should be noted that when the difference between the two parts of the second connector is a differential value, the second preset difference threshold is a second preset difference threshold. When the difference between the two parts of the second connector is a ratio, the second preset difference threshold is a second preset ratio threshold.

[0142] It is understood that, in this embodiment of the present disclosure, by setting the difference between the area of ​​the first part and the area of ​​the second part to be less than a first preset difference threshold, the first part and the second part can be kept in balance when welded separately, thereby making the first connector easier to assemble.

[0143] Furthermore, by setting the difference between the area of ​​the fourth part and the area of ​​the third part to be less than the second preset difference threshold, the third part and the fourth part can be kept in balance when welded separately, thereby making the second connector easier to assemble.
