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. Furthermore, the trend towards ultra-thin and lightweight designs in terminal devices makes electrostatic discharge (ESD) protection for radio frequency (RF) devices in the communication link particularly important. Current ESD protection technologies either involve adding transient voltage suppressors (TVS) or low-temperature co-fired ceramic (LTCC) filters, which present limitations in ESD protection design and increase material costs. Utility Model Content

[0003] To overcome the problems existing in related technologies, this disclosure provides an antenna structure and terminal device that can improve the flexibility of device layout on a circuit board.

[0004] According to a first aspect of the present disclosure, an antenna structure is provided, comprising:

[0005] Antenna radiator;

[0006] A suspended conductive element is spaced apart from the antenna radiator and is used to transmit and receive wireless signals after coupling with the antenna radiator;

[0008] Wherein, at least one of the tuning matching circuits has at least two grounding branches arranged in parallel;

[0009] The grounding branch, the floating conductive element, and the conductive spring assembly of each of the tuning matching circuits together constitute an electrostatic discharge path.

[0010] This embodiment of the disclosure achieves electrostatic discharge (ESD) protection to reduce ESD damage to the antenna structure without the need for expensive LTCC filters. This not only reduces material costs but also decreases the footprint of the LTCC filter, increasing the flexibility of component placement on the circuit board.

[0015] The second conductive spring is grounded through a second tuning matching circuit, which has at least two grounding branches.

[0016] This embodiment of the invention discharges electrostatic energy by setting at least four grounding branches, thereby reducing the electrostatic energy conducted to the antenna radiator through the suspended conductive parts by improving the discharge capability of the antenna structure, thus achieving electrostatic protection of the antenna structure.

[0017] In some embodiments, the impedance elements connected to different grounding branches in the tuning matching circuit connected to the same conductive spring are different;

[0018] The impedance elements connected to each of the grounding branches include: resistors, capacitors, and / or inductors.

[0019] The embodiments disclosed herein utilize different impedance elements connected to different grounding branches of the same conductive spring. This allows for more flexible layout of the impedance components and enables effective discharge of static electricity by utilizing the characteristics of different impedance elements, thereby better protecting the antenna structure from electrostatic damage.

[0020] In some embodiments, the antenna radiator operates in the Wi-Fi band, millimeter-wave antenna band, Bluetooth antenna band, satellite antenna band, and / or ultra-wideband antenna band.

[0022] In some embodiments, the suspended conductive element includes a suspended conductive ring or a suspended conductive spring.

[0023] The embodiments disclosed herein, by setting a suspended conductive component including a suspended conductive ring or a suspended conductive spring, enable the antenna structure to be applied to more flexible scenarios.

[0024] According to a second aspect of the present disclosure, a terminal device is provided, comprising:

[0025] Circuit board;

[0026] The antenna structure as described in the first aspect above;

[0027] Each grounding branch in the antenna structure is located on the circuit board and connected to the grounding layer of the circuit board.

[0028] In some embodiments, the conductive springs in the antenna structure are disposed in different areas on the circuit board;

[0029] Each of the grounding branches connected to the same conductive spring is arranged around the area where the same conductive spring is located.

[0030] In some embodiments, the first conductive spring of the antenna structure is disposed in a first region of the circuit board;

[0031] The second conductive spring of the antenna structure is disposed in a second region of the circuit board that is different from the first region.

[0032] Multiple grounding branches connected to the first conductive spring are arranged around the first area;

[0033] The plurality of grounding branches connected to the second conductive spring are arranged around the second region.

[0034] In some embodiments, the terminal device includes:

[0035] case;

[0036] The display module has a module decorative element exposed outside the housing;

[0037] The module decorative element has a decorative element barrel that protrudes from the module decorative element and is used to decorate the camera of the display module;

[0038] The decorative component cannon barrel is reused as a suspended conductive component of the antenna structure;

[0039] A portion of the conductive area in the module decorative component is spaced apart from the barrel of the decorative component and reused as the antenna radiator of the antenna structure.

[0040] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0041] In this embodiment, the conductive spring assembly connecting the suspended conductive element is grounded through at least two tuning matching circuits, and at least one tuning matching circuit has at least two grounding branches connected in parallel. That is, this embodiment can significantly increase the discharge capacity of the electrostatic discharge path by adding grounding branches, allowing more electrostatic energy to be conducted to the electrostatic discharge path, thereby reducing the electrostatic energy conducted from the suspended conductive element to the antenna radiator, and achieving electrostatic protection.

[0042] Thus, this embodiment of the present disclosure achieves electrostatic protection to reduce electrostatic damage to the antenna structure without the need for expensive LTCC filters. This not only reduces material costs but also decreases the footprint of the LTCC filter, improving the flexibility of device layout on the circuit board. Furthermore, this embodiment of the present disclosure does not require the addition of TVS devices, thereby reducing RF spurious emissions caused by TVS device nonlinearity and ensuring that the antenna structure's RSE complies with regulatory requirements.

[0054] 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.

[0055] This disclosure provides an antenna structure. Figure 1 This is a schematic diagram illustrating the antenna structure of the present disclosure according to an exemplary embodiment. Figure 1 As shown, the antenna structure includes:

[0056] Antenna radiator 101;

[0057] The suspended conductive element 102 is spaced apart from the antenna radiator 101 and is used to transmit and receive wireless signals after coupling with the antenna radiator 101.

[0058] The conductive spring assembly 103 is connected at one end to the suspended conductive element 102, and the other end is grounded through at least two tuning matching circuits.

[0059] At least one of the tuning matching circuits has at least two grounding branches 104 arranged in parallel;

[0060] The grounding branch 104, the floating conductive element 102, and the conductive spring assembly 103 of each of the tuning matching circuits together constitute an electrostatic discharge path.

[0061] In this embodiment, the antenna structure is applied in scenarios requiring electrostatic discharge (ESD) protection. For example, when the antenna structure is subjected to ESD, the ESD discharge path capability of the antenna structure can be improved by providing at least two grounding branches of the tuning matching circuits in the antenna structure, thereby eliminating the need for a TVS device.

[0062] The aforementioned antenna radiator is used for transmitting and receiving wireless signals. This antenna radiator can be installed inside or outside the terminal device; this disclosure does not impose any limitations on its placement.

[0063] It should be noted that the antenna radiator can operate in different antenna frequency bands.

[0064] In some embodiments, the antenna radiator may operate in the Wi-Fi band. Here, the Wi-Fi band may include the 2.4 GHz Wi-Fi band or the 5 GHz Wi-Fi band.

[0065] In other embodiments, the antenna radiator may also operate in the millimeter-wave antenna band, satellite antenna band, ultra-wideband antenna band, and / or Bluetooth antenna band.

[0066] It is understood that the embodiments disclosed herein can operate in different antenna frequency bands, thus expanding the applicable scenarios.

[0067] In this embodiment of the disclosure, the suspended conductive element can be understood as a device that does not directly contact the motherboard or housing of the terminal device, but is connected through a conductive spring assembly or other devices.

[0068] Here, the suspended conductive element is spaced apart from the antenna radiator. That is, the suspended conductive element does not contact the antenna radiator, thus allowing coupling to occur between the suspended conductive element and the antenna radiator.

[0069] In this embodiment of the disclosure, the suspended conductive element can operate in the same frequency band after being coupled with the antenna radiator.

[0070] Here, when the antenna radiator is operating in the WIFI frequency band, the suspended conductive component can also operate in the WIFI frequency band.

[0071] It should be noted that the shape of the suspended conductive element can be set according to actual needs. In some embodiments, the suspended conductive element includes a suspended conductive ring or a suspended conductive spring.

[0072] Here, the suspended conductive ring may include a suspended conductive circular ring, a suspended conductive square ring, etc.

[0073] It is understood that by providing a suspended conductive component, including a suspended conductive ring or a suspended conductive spring, the antenna structure can be applied to more flexible scenarios.

[0074] In this embodiment of the disclosure, the conductive spring assembly may be composed of at least one conductive spring. In some embodiments, the conductive spring assembly may include a single conductive spring that is grounded through at least two tuning matching circuits;

[0075] In other embodiments, the conductive spring assembly may include multiple conductive springs. If the number of conductive springs is equal to the number of tuning matching circuits, then each conductive spring is grounded through a tuning matching circuit. If the number of conductive springs is not equal to the number of tuning matching circuits, then one conductive spring may be grounded through multiple tuning matching circuits, or multiple conductive springs may be grounded through a single tuning matching circuit.

[0076] In this embodiment of the present disclosure, at least one tuning matching circuit has at least two ground branches connected in parallel. Each ground branch of the tuning matching circuit can form an electrostatic discharge path with the floating conductive element and the conductive spring assembly.

[0077] In other words, each grounding branch of the tuning matching circuit in the embodiments of this disclosure can be used not only for antenna tuning matching, but also for discharging static electricity to form a static discharge path.

[0078] It should be noted that the more grounding branches there are, the greater the discharge capacity of the corresponding electrostatic discharge path, thus enabling better effective electrostatic discharge.

[0079] Here, with two tuning matching circuits and each tuning matching circuit having two grounding branches, the electrostatic energy on the suspended conductive element is conducted to the conductive spring assembly and can be discharged through the four grounding branches.

[0080] With two tuning matching circuits, and each tuning matching circuit having three grounding branches, the electrostatic energy on the suspended conductive element can be discharged through the six grounding branches after passing through the conductive spring assembly.

[0081] In this embodiment of the disclosure, such as Figure 1 As shown, each grounding branch 104 is connected to an impedance element 105. Through the impedance characteristics of the impedance element 105 in each grounding branch 104, static electricity is effectively discharged, reducing the damage to antenna devices caused by static electricity accumulation.

[0082] Impedance elements include resistors, capacitors, and / or inductors.

[0083] For example, Figure 2 This is a circuit for electrostatic discharge protection design in the related art, illustrated according to an exemplary embodiment. Figure 1 .like Figure 2 As shown, a TVS device 203 is reserved in the connection line between the first RF matching 201 of the antenna and the RF test socket 202 to reduce electrostatic damage. However, due to the nonlinear characteristics of the TVS device, the radiated spurious emissions (RSE) of the antenna can easily exceed regulatory requirements, necessitating recalibration of the antenna matching circuit.

[0084] Figure 3 This is a circuit for electrostatic discharge protection design in the related art, illustrated according to an exemplary embodiment. Figure 2 .like Figure 3 As shown, a second radio frequency matching 302 is connected between the low noise amplifier 301 and the antenna radiator. A first LTCC filter 305 and a ground inductor 303 or resistor 304 need to be added to the connection line of the second radio frequency matching 302 to form an electrostatic discharge protection circuit to achieve electrostatic discharge protection.

[0085] Figure 4 Is Figure 3 The circuit diagram for electrostatic discharge protection using an LTCC filter is shown in the example. Figure 4 As shown, the decorative antenna includes an antenna radiator 101 and a suspended conductive element 102. Static electricity can be conducted to the antenna radiator through the suspended conductive element via spatial coupling, thereby causing electrostatic damage to the antenna device. Based on this, related technologies such as... Figure 4 The second LTCC filter 401 is connected to the antenna radiator 101 via the antenna connector 402 and the antenna matching 403, and is grounded on the side of the floating conductive element 102 via two grounding matching circuits 404. In this way, the electrostatic energy transmitted from the floating conductive element to the antenna radiator can be reduced by adding a second LTCC filter to minimize electrostatic damage. However, this not only increases material costs but also makes the circuit board layout more constrained due to the limited space required to place the second LTCC filter.

[0086] Based on this, embodiments of this disclosure propose that the conductive spring assembly connecting the suspended conductive element is grounded through at least two tuning matching circuits, and at least one tuning matching circuit has at least two grounding branches arranged in parallel. In other words, embodiments of this disclosure significantly increase the discharge capacity of the electrostatic discharge path by adding grounding branches, allowing more electrostatic energy to be conducted to the electrostatic discharge path, thereby reducing the electrostatic energy conducted from the suspended conductive element to the antenna radiator, and achieving electrostatic protection.

[0087] Thus, this embodiment of the present disclosure achieves electrostatic protection to reduce electrostatic damage to the antenna structure without the need for expensive LTCC filters. This not only reduces material costs but also decreases the footprint of the LTCC filter, improving the flexibility of device layout on the circuit board. Furthermore, this embodiment of the present disclosure does not require the addition of TVS devices, thereby reducing RF spurious emissions caused by TVS device nonlinearity and ensuring that the antenna structure's RSE complies with regulatory requirements.

[0088] For example, Figure 5 This is a circuit diagram illustrating the electrostatic protection of the antenna structure of this disclosure as a decorative antenna, as shown in an embodiment of this disclosure. Figure 5As shown, the antenna structure may also include a Wi-Fi Wireless Connectivity Network (WCN) chip 106, a front-end module (FEM) 107, an antenna connector 402, and an antenna matching 403.

[0089] Among them, the WCN chip 106 is connected to the antenna radiator 101 through the radio frequency front-end module 107, the antenna connector 402 and the antenna matching 403. The floating conductive component 102 is connected to four grounding branches 104 through the first conductive spring 103A and the second conductive spring 103B, thus realizing the discharge of electrostatic energy through the four grounding branches 104.

[0090] Compared to related technologies that use LTCC filters and two grounding branches for electrostatic protection, the embodiments of this disclosure increase the number of grounding branches connecting the conductive spring assembly, i.e., as... Figure 5 As shown, four grounding branches 104 are set up so that all four grounding branches 104 can discharge static electricity, thereby achieving effective discharge of static electricity to reduce static damage, and thus eliminating the need for an LTCC filter.

[0091] In some embodiments, such as Figure 1 and Figure 5 As shown, the conductive spring assembly 103 includes at least two conductive springs (such as...). Figure 5 The first conductive spring 103A and the second conductive spring 103B are respectively grounded through at least one of the tuning matching circuits.

[0092] In this embodiment of the disclosure, when the conductive spring assembly consists of at least two conductive springs, each conductive spring is grounded through at least one tuning matching circuit. That is, each conductive spring can be used to conduct electrostatic energy from the suspended conductive element.

[0093] It should be noted that the more conductive contacts an electric contact assembly includes, the more grounding branches it will have, and thus the greater the discharge capacity of the electrostatic discharge path.

[0094] For example, when there are two conductive springs, each of the two conductive springs is grounded through at least one tuning matching circuit. In this case, if each conductive spring is connected to a tuning matching circuit, and the tuning matching circuit includes two grounding branches, then the electrostatic energy of the suspended conductive component can be discharged through four grounding branches.

[0095] For example, when there are three conductive springs, each of the three conductive springs is grounded through at least one tuning matching circuit. In this case, if each conductive spring is connected to a tuning matching circuit, and the tuning matching circuit includes two grounding branches, then the electrostatic energy of the suspended conductive component can be discharged through six grounding branches.

[0096] Understandably, by setting at least one conductive spring, the design of the electrostatic discharge path can be made more flexible, and the discharge capacity of the electrostatic discharge path can be improved.

[0097] In some embodiments, such as Figure 5 As shown, at least two of the conductive springs include a first conductive spring 103A and a second conductive spring 103B;

[0098] The first conductive spring 103A is grounded through a first tuning matching circuit, which has at least two grounding branches 104.

[0099] The second conductive spring 103B is grounded through a second tuning matching circuit, which has at least two grounding branches 104.

[0100] In this embodiment, the first conductive spring and the second conductive spring are both connected to the suspended conductive element and can be used to conduct electrostatic energy. Here, the first conductive spring and the second conductive spring can be connected to any two positions of the suspended conductive element; for example, the first conductive spring and the second conductive spring can be connected to two opposite positions of the suspended conductive element.

[0101] It should be noted that the first conductive spring can be connected to at least two grounding branches, and the second conductive spring can also be connected to at least two grounding branches, so that electrostatic energy is discharged through at least four grounding branches.

[0102] It is understood that by setting at least four grounding branches to discharge electrostatic energy, the electrostatic energy conducted to the antenna radiator through the suspended conductive parts can be reduced by improving the discharge capability of the antenna structure, thereby achieving electrostatic protection of the antenna structure.

[0103] In some embodiments, such as Figure 5 As shown, connected to the same conductive spring (such as...) Figure 5 The impedance elements connected to different grounding branches 104 in the tuning matching circuit of the first conductive spring 103A or the second conductive spring 103B are different.

[0104] The impedance elements connected to each of the grounding branches include: resistors, capacitors, and / or inductors.

[0105] In this embodiment of the disclosure, when there are two grounding branches connected to the same conductive spring, the impedance components connected to the two grounding branches are different; when there are three grounding branches connected to the same conductive spring, the impedance components connected to the three grounding branches are different.

[0106] For example, such as Figure 5 As shown, the first conductive spring 103A is connected to two grounding branches 104, one grounding branch 104 is connected to a resistor R3, and the other grounding branch 104 is connected to an inductor L4.

[0107] The second conductive spring 103B is connected to two grounding branches 104, one of which is connected to a resistor R4, and the other is connected to an inductor L3.

[0108] It is understandable that by connecting different grounding branches to the same conductive spring with different impedance elements, on the one hand, the layout of the impedance components can be more flexible, and on the other hand, the characteristics of different impedance elements can be used to achieve effective discharge of static electricity, thereby better protecting the antenna structure from static damage.

[0109] This disclosure also proposes a terminal device. For example... Figure 6A As shown, the terminal device includes:

[0110] Circuit board 601;

[0111] Antenna structures as described in one or more of the above embodiments;

[0112] Each grounding branch 104 and conductive spring assembly 103 in the antenna structure are disposed on the circuit board 601 and connected to the ground layer 602 of the circuit board 601.

[0113] The aforementioned terminal devices may include smartphones, tablets, laptops, or wearable devices, including smartwatches or smart bracelets.

[0114] In this embodiment of the disclosure, the antenna structure can be grounded at a single point through each grounding branch, that is, each grounding branch is connected to the ground plane of the circuit board at a single point. In other words, by using each grounding branch to be connected to the ground plane at a single point, the electrostatic energy can be discharged to the ground plane of the circuit board, reducing electrostatic damage caused by the accumulation of a large amount of static electricity.

[0115] It is understandable that the terminal equipment includes an antenna structure. By adding a grounding branch to the antenna structure, the discharge capacity of the electrostatic discharge path is significantly increased, allowing more electrostatic energy to be conducted to the electrostatic discharge path. This reduces the electrostatic energy conducted from the suspended conductive parts to the antenna radiator, thus achieving electrostatic protection.

[0116] Thus, this embodiment of the present disclosure achieves electrostatic protection to reduce electrostatic damage to the antenna structure without the need for expensive LTCC filters. This not only reduces material costs but also decreases the footprint of the LTCC filter, improving the flexibility of device layout on the circuit board. Furthermore, this embodiment of the present disclosure does not require the addition of TVS devices, thereby reducing RF spurious emissions caused by TVS device nonlinearity and ensuring that the antenna structure's RSE complies with regulatory requirements.

[0117] In some embodiments, the conductive springs in the antenna structure are disposed in different areas on the circuit board;

[0118] Each of the grounding branches connected to the same conductive spring is arranged around the area where the same conductive spring is located.

[0119] In this embodiment of the disclosure, when there are multiple grounding branches connected to the same conductive spring, the multiple grounding branches may surround the same side or different sides of the area where the same conductive spring is located.

[0120] For example, when there are two grounding branches connected to the same conductive spring, the two grounding branches can surround different sides of the area where the same conductive spring is located.

[0121] In this embodiment, each conductive spring is disposed in a different area of ​​the circuit board. The distribution of these different areas can be set according to the actual situation, and this embodiment does not limit this.

[0122] For example, the terminal device also includes a display module mounted on a circuit board and occupying a third area of ​​the circuit board, around which different conductive springs can be mounted on the circuit board.

[0123] In this embodiment of the disclosure, when installing conductive springs on the circuit board, a clearance process is required, that is, a hollowing-out process is performed at the location of the conductive springs to reduce the low antenna RF performance caused by the parasitic coupling effect of the metal, thereby improving the antenna performance.

[0124] Understandably, setting up each grounding branch around the same area where the conductive spring is located allows the conductive spring to be grounded better through the grounding branch, and also makes static discharge more flexible.

[0125] In some embodiments, such as Figure 5 and Figure 7 As shown, the first conductive spring 103A of the antenna structure is disposed in the first region 603 of the circuit board 601;

[0126] The second conductive spring 103B of the antenna structure is disposed in a second region 604 of the circuit board 601, which is different from the first region 603.

[0127] A plurality of grounding branches 104 connected to the first conductive spring 103A are arranged around the first region 603;

[0128] A plurality of grounding branches 104 connected to the second conductive spring 103B are arranged around the second region 604.

[0129] In this embodiment of the present disclosure, a plurality of grounding branches connected to the first conductive spring are arranged around the first region. The plurality of grounding branches connected to the first conductive spring may be arranged at intervals on the same side of the first region, or at intervals on different sides of the first region (such as adjacent sides or opposite sides).

[0130] For example, such as Figure 5 and Figure 7 As shown, the resistor R3 and inductor L4 of the two grounded branches 104 connected to the first conductive spring 103A are distributed on opposite sides of the first region 603.

[0131] In this embodiment of the present disclosure, multiple grounding branches connected to the second conductive spring are arranged around the second region. These multiple grounding branches connected to the second conductive spring can be spaced out on the same side of the second region, or spaced out on different sides of the second region (such as adjacent sides or opposite sides).

[0132] For example, such as Figure 5 and Figure 7 As shown, the resistor R4 and inductor L3 of the two grounding branches 104 connected to the second conductive spring 103B are distributed on adjacent sides of the second region 604.

[0133] It is understandable that by setting two conductive springs on the upper part of the circuit board and connecting multiple grounding branches accordingly, not only can more effective static discharge be achieved, but also more flexible settings for different grounding branches can be made.

[0134] In some embodiments, such as Figure 5 and Figure 6B As shown, the terminal device includes:

[0135] case;

[0136] The display module has a module decorative element 605 exposed outside the housing;

[0137] The module decorative element 605 has a decorative element barrel 606 that protrudes from the module decorative element 605 and is used to decorate the camera of the display module;

[0138] The decorative component, the barrel 606, is reused as the suspended conductive component 102 of the antenna structure;

[0139] A portion of the conductive area 607 in the module decorative component 605 is spaced apart from the decorative component barrel 606 and reused as the antenna radiator 101 of the antenna structure.

[0140] In this embodiment of the disclosure, the housing may be the back cover of the terminal device, the circuit part of the display module is disposed on the circuit board, and the camera of the display module is exposed through the back cover.

[0141] Here, the display module may include not only a camera but also a flash. The camera and flash can be decorated together using module trim pieces. For example, Figure 6B As shown, the module decorative parts can be square, and the side length of the square can be set according to actual needs, for example, it can be set to 39 mm.

[0142] In this embodiment, the decorative element barrel is mounted outside the camera and surrounds the camera. Here, as... Figure 6B As shown, the decorative part, the barrel 606, can be ring-shaped.

[0143] It should be noted that, due to the coupling effect, the conductive areas of the decorative part barrel and the module decorative part do not contact each other, thus forming a decorative antenna.

[0144] It is understandable that the decorative barrel can both decorate the camera and, together with the conductive spring and grounding branch, form an electrostatic discharge path to discharge static electricity, thus achieving a dual function. Therefore, by reusing the decorative barrel, this embodiment of the present disclosure can enrich the functionality of the same device. Furthermore, by setting the decorative barrel to protrude from the pattern decoration, the aesthetics and technological feel of the terminal device can be enhanced.

[0147] Processing component 802 typically controls the overall operation of the terminal device, such as operations associated with at least one of display, telephone call, data communication, camera operation, and recording operation.

Furthermore, processing component 802 may include one or more modules to facilitate interaction between processing component 802 and other components.
