Description

Technical Field

[0001] This application relates to the field of antenna technology, and in particular to an antenna assembly, antenna system and terminal. Background Technology

[0002] MIMO (Multiple-Input Multiple-Output) antenna technology represents a major breakthrough in antenna technology for wireless mobile communications. This technology can significantly increase the capacity and spectral efficiency of a communication system without increasing bandwidth, making it a crucial technology for next-generation mobile communication systems. MIMO technology allows multiple antennas to simultaneously transmit and receive multiple spatial streams, and can distinguish signals originating from or destined for different spatial locations. The application of multi-antenna systems enables the simultaneous transmission of parallel data streams. Furthermore, using multiple antennas at the transmitting or receiving end can significantly overcome channel fading and reduce the bit error rate.

[0003] To achieve a better signal experience, terminal devices are increasingly using more antennas, making antenna coupling a significant concern. Traditional decoupling layouts increase antenna spacing to ensure sufficient isolation between adjacent antennas. While this approach can mitigate antenna coupling to some extent, for small devices like mobile terminals, the limited distance between antennas makes ideal placement impossible. The close physical proximity of antennas inevitably leads to interference, and increasing antenna spacing cannot simultaneously meet the requirements of both small device size and interference resistance.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0044] Please see Figure 1 This application provides an antenna system, including one or more antenna components 1, which are used to transmit signals.

[0045] In some embodiments, multiple antenna assemblies 1 are provided to improve signal transmission capability. The multiple antenna assemblies 1 are spaced apart, and the distance between adjacent antenna assemblies 1 is greater than the distance between two antennas 11 within a single antenna assembly 1, so that the distance between adjacent antenna assemblies 1 is as large as possible within the limited space of the terminal device, avoiding mutual interference between adjacent antenna assemblies 1. The distance between two antennas 11 within an antenna assembly 1 is as small as possible to save space.

[0046] Furthermore, the antenna system also includes a grounding terminal 2 and multiple signal sources 3. The antenna 11 is electrically connected to the signal sources 3, and the conductive element 12 is connected to the grounding terminal 2 so that the antenna 11 can transmit signals according to the signal sources 3. The conductive element 12 is grounded so that the conductive element 12 can isolate the antenna 11 and avoid mutual interference between adjacent antennas 11.

[0047] It should be noted that this antenna system can be applied to mobile terminals as well as some fixed terminals, and to both large and small devices, as long as the device requires signal transmission. If the antenna system is applied to a mobile terminal, such as a mobile phone, then ground terminal 2 can be the metal frame or the entire metal casing of the phone, without limitation, as long as it can serve as a ground wire.

[0048] It should also be noted that the conductive element 12 can be rod-shaped, plate-shaped, or other irregular shapes, without limitation. The shape of the antenna 11 is also not limited; it can be cylindrical, prismatic, or other non-prismatic structures, without limitation. In this embodiment, for ease of subsequent structural description, the conductive element 12 is rod-shaped, and the antenna 11 is prismatic, specifically cuboid, which are common shapes for the conductive element 12 and the antenna 11.

[0049] Please see Figure 2 In some embodiments, the antenna assembly 1 includes a conductive element 12 and two antennas 11 spaced apart from each other. The conductive element 12 is disposed between the two antennas 11, and its two ends are respectively inserted into the receiving cavities 111 of the two antennas 11 and insulated from the antennas 11. The conductive element 12 is grounded.

[0050] The technical solution provided in this application inserts the conductive element 12 into two adjacent antennas 11 on both sides, thereby utilizing the internal space of the antenna 11 to accommodate part of the conductive element 12, improving the space utilization of the antenna assembly 1, and enabling the conductive element 12 to adapt to situations where the spacing between the two antennas 11 is limited. Furthermore, by insulating the conductive element 12 from the antennas 11 and grounding the conductive element 12, the conductive element 12 can isolate the two adjacent antennas 11, thereby improving the isolation between the two adjacent antennas 11 and reducing mutual interference between them.

[0051] It should be noted that the shape of the conductive element 12 is not limited, as long as it can be disposed between the two antennas 11 and inserted into the corresponding receiving cavity 111. The material of the conductive element 12 is also not limited, as long as it has good conductivity, it can be a metal with good conductivity, such as copper or silver.

[0052] In some embodiments, the conductive element 12 is spaced apart from the inner wall of the receiving cavity 111 to avoid the conductive element 12 from contacting the inner wall of the receiving cavity 111, i.e. the physical part of the antenna 11, which would cause the two antennas 11 to be connected due to the conductive element 12, resulting in a circuit failure and inability to work.

[0053] Further, please see Figure 2 The antenna assembly 1 also includes an insulating member 114 located within the receiving cavity 111 to isolate the conductive member 12 from the antenna 11. The insulating member 114 can be first fitted onto both ends of the conductive member 12, and then inserted into the receiving cavity 111 through the conductive member 12, thereby entering the receiving cavity 111 together with the insulating member 114 to achieve an insulated connection between the conductive member 12 and the antenna 11. Alternatively, the insulating member 114 can be pre-installed in the receiving cavity 111, with corresponding holes for the conductive member 12 to be inserted. The conductive member 12 is then inserted into the receiving cavity 111 and into the holes of the insulating member 114, achieving insulation between the conductive member 12 and the antenna 11. The insulating component 114 can also be achieved by first inserting the conductive component 12 into the receiving cavity 111, with the conductive component 12 and the inner wall of the receiving cavity 111 kept at a distance and not in contact, and then performing injection molding to fill the receiving cavity 111 with insulating injection molding material and fix it, thus finally completing the fixation of the conductive component 12 and the antenna 11 and the insulation isolation between the conductive component 12 and the antenna 11.

[0054] In some embodiments, see Figures 2 to 3 Each antenna 11 has a first opening 112 that connects to the receiving cavity 111. The first openings 112 of the two antennas 11 are arranged opposite each other so that the distance between the two first openings 112 is minimized, thereby making the length of the conductive element 12 that needs to be inserted into the two first openings 112 as short as possible and reducing the space occupied by the conductive element 12.

[0055] In other embodiments, each antenna 11 has a first opening 112 that connects to the receiving cavity 111, and the first openings 112 of the two antennas 11 are staggered. This type of case is mainly applicable to conductive elements 12 with a non-linear rod shape, ensuring that the two ends of the conductive adhesive can be inserted into the receiving cavities 111 of the two antennas 11 respectively.

[0056] Please see Figure 10In some embodiments, each antenna 11 has a second opening 113 communicating with a receiving cavity 111. The outline of the second opening 113 extends along the length direction of the antenna 11 to the first opening 112, so that the conductive element 12 can be placed into the receiving cavity 111 through the second opening 113. Exemplarily, the antenna 11 is cuboid in shape, and the first opening 112 is opened on one side of the antenna 11 along its length direction, i.e., the bottom side or the top side. The second opening 113 is opened on one of the side sides between the bottom side and the top side, and the second opening 113 extends to the first opening 112, so as to avoid the existence of a side of the antenna 11 coplanar with the second opening 113 between the second opening 113 and the first opening 112, which would cause the conductive element 12 to interfere with the side of the antenna 11 when it is directly placed into the receiving cavity 111 through the second opening 113.

[0057] In some embodiments, see Figure 4 The two antennas 11 are symmetrically arranged about one axis. In other embodiments, the two antennas 11 may also be asymmetrically arranged, such as having unequal lengths. Detailed experimental descriptions of the symmetrical and asymmetrical antenna configurations will follow, and will not be repeated here.

[0058] In some embodiments, see Figure 1 and Figure 2 The antenna assembly 1 also includes a first matching module 15, which is electrically connected to at least one antenna 11 and is used to adjust the resonant frequency of the antenna 11. The first matching module 15 can be a circuit composed of capacitors and inductors. The resonant frequency of the antenna 11 is adjusted using capacitors and inductors. How the first matching module 15 adjusts the resonant frequency of the antenna 11 is prior art. Besides capacitors and inductors, the first matching module 15 can also have other structures, as long as it can achieve the adjustment of the resonant frequency of the antenna 11. Further details will not be elaborated here.

[0059] Furthermore, there are multiple first matching modules 15, each of which is electrically connected to an antenna 11 to achieve independent adjustment of the resonant frequency of each antenna 11, which facilitates independent control of multiple antennas 11 and makes the process more flexible.

[0060] In some embodiments, the antenna assembly 1 further includes a second matching module 16, with the conductive element 12 electrically connected to the second matching module 16, for adjusting the parasitic capacitive reactance and inductive reactance of the conductive element 12, so that the decoupling frequency is aligned with the resonant frequency of the antenna 11, thereby improving the isolation between the two antennas 11.

[0061] It should be noted that the conductive component 12 is connected to the second matching module 16, and the two antennas 11 are respectively connected to the two first matching modules 15, so that the conductive component 12 and the two antennas 11 form a parallel structure. This parallel structure can effectively reduce the inductance per unit length of the conductive component 12, thereby optimizing the overall length of the conductive component 12 and making it more conducive to improving space utilization.

[0062] In some embodiments, the antenna system further includes multiple signal sources 3, and the antenna assembly 1 further includes multiple first signal connectors 13 and second signal connectors 14. Each signal source 3 is connected to an antenna 11 through a first signal connector 13, and the first signal connector 13 is electrically connected to a first matching module 15. Each conductive element 12 is connected to a second signal connector 14, with the end of the second signal connector 14 away from the conductive element 12 grounded, and the connection path of the second signal connector 14 passes through a second matching module 16 and is electrically connected to the second matching module 16. It should be noted that the structures of the first signal connectors 13 and the second signal connectors 14 can be the same, both serving the function of electrical connection. They can be in the form of wires, or other metal media, conductive springs, etc., without limitation.

[0063] In some embodiments, the spacing between two mutually spaced antennas 11 ranges from 1 mm to 2.5 mm. For example, the spacing between two adjacent antennas 11 can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, etc., without limitation. In subsequent experiments, the spacing between two adjacent antennas was set to 1.5 mm.

[0064] Please see Figure 14 and Figure 15 In related technologies, no conductive element 12 is provided between the two antennas 11, and there are obvious common ground current coupling and space wave coupling phenomena between the two antennas 11.

[0065] Please see Figure 12 and Figure 13 In this embodiment, after the conductive element 12 is introduced, the portions of the two antennas 11 used to accommodate the conductive element 12 together form a resonator. When the resonator is in a resonant state, the conductive element 12 can effectively suppress the common-ground wave coupling between the two antennas 11. Furthermore, from the perspective of the radiation field, the secondary resonance generated by the resonator can cancel the spatial wave coupling between the two antennas 11. Therefore, by adjusting the resonant frequency of the resonant cavity, the isolation of the target frequencies of the two antennas 11 can be significantly improved.

[0066] In some embodiments, see Figures 4 to 7 The two antennas 11 are symmetrically arranged about one axis. Based on this structural relationship, the following experiment is conducted to verify it:

[0067] Performance verification was performed using electromagnetic simulation tools in the 2.4 GHz to 2.5 GHz Wi-Fi band. Please refer to [link / reference]. Figure 5 The spacing between the two antennas 11 is 1.5 mm. A conductive element 12 is disposed between two adjacent antennas 11, with both ends of the conductive element 12 embedded in the receiving cavity 111 of each antenna 11, and the conductive element 12 is kept in a non-contact state with the inner wall of the receiving cavity 111. The electrical length of both antennas 11 is λ / 4. Due to the large thickness of the antennas 11, the physical length of the antennas 11 is shortened to λ / 8. Due to the embedded structure of the conductive element 12 and the antennas 11, as well as the shortening effect of the parallel second matching module 16, the length of the conductive element 12 is approximately 1 / 2 of the physical length of the antennas 11, i.e., λ / 16. By adjusting the first matching module 15, the resonant frequency of the two antennas 11 is adjusted to the mid-frequency of 2.45 GHz in the 2.4 GHz to 2.5 GHz band. At the same time, by optimizing the length of the second matching module 16 and the conductive element 12, the isolation between the two antennas 11 is optimized.

[0068] like Figure 5 As shown, line A represents the isolation trend between the two antennas 11 of a conventional antenna assembly 1 without the conductive element 12, while line B represents the isolation trend between the two antennas 11 of an antenna assembly 1 in this embodiment, which has the conductive element 12 and whose two antennas 11 are symmetrical about an axis. Comparing lines A and B, it can be seen that with the addition of the conductive element 12 and at a frequency around 2.5 GHz, the isolation between the two antennas 11 increases from -3 dB to approximately -20 dB, indicating a very significant decoupling effect.

[0069] Please see Figure 6 Line a represents the radiation efficiency trend of one antenna 11 in a conventional antenna assembly 1 without the conductive element 12. Line b represents the overall system efficiency trend of one antenna 11 in a conventional antenna assembly 1 without the conductive element 12. Line c represents the radiation efficiency trend of one antenna 11 in an antenna assembly 1 with the conductive element 12 and two antennas 11 symmetrical about an axis in this embodiment. Line d represents the overall system efficiency trend of one antenna 11 in an antenna assembly 1 with the conductive element 12 and two antennas 11 symmetrical about an axis in this embodiment. Comparing lines a and c, and lines b and d, it can be seen that after adding the conductive element 12, at a frequency of approximately 2.5 GHz, the radiation efficiency and overall system efficiency of antenna 11, i.e., the overall performance of antenna 11, are improved by up to approximately 2.7 dB. In this embodiment, since the two antennas 11 are symmetrical, their performance is consistent, so the comparison results of the other antenna 11 will not be described again.

[0070] In practical applications, 2.4G Wi-Fi and 5G Wi-Fi typically share a single antenna 11. By adjusting the first matching module 15, resonant coverage of both the 2.4G Wi-Fi and 5G Wi-Fi frequency bands can be achieved. Figure 7 As shown, line C represents the overall system efficiency trend of one antenna 11 of the antenna assembly 1 provided in this embodiment that is not compatible with 5G Wi-Fi, while line D represents the overall system efficiency trend of one antenna 11 of the antenna assembly 1 provided in this embodiment that is compatible with 5G Wi-Fi. Comparing lines C and D, it can be seen that the performance of the antenna 11 compatible with 5G Wi-Fi is slightly reduced, by approximately 0.3 dB, which is within an acceptable range. Therefore, adding the conductive element 12 will not affect the multi-band tuning performance of the antenna 11.

[0071] In some embodiments, see Figure 8 The two antennas 11 have unequal lengths. Based on this structural relationship, the following experiment will verify this:

[0072] Performance verification was performed using electromagnetic simulation tools in the 2.4 GHz to 2.5 GHz Wi-Fi band. Please refer to [link / reference]. Figure 8 One antenna 11 is configured as a GPS and 2.4GHz Wi-Fi multi-band antenna 11, and the other antenna 11 is configured as a 2.4GHz single-band antenna 11, which is used to verify the decoupling performance of different types of antennas 11 in the 2.4GHz Wi-Fi band.

[0073] Please see Figure 9 Line E represents the isolation trend of antenna assembly 1 with one antenna 11 serving as a multi-band antenna for GPS and 2.4GHz Wi-Fi, and the other antenna 11 serving as a single-band 2.4GHz antenna. Line F represents the isolation trend of antenna assembly 1 with one antenna 11 serving as a multi-band antenna for GPS and 2.4GHz Wi-Fi, and the other antenna 11 serving as a single-band 2.4GHz antenna. Comparing lines E and F, it can be seen that for different types of antennas 11 operating at the same or different frequencies, the isolation of antenna 11 with conductive element 12 is improved from -4dB to -14dB compared to antenna 11 without conductive element 12. The conductive element 12 consistently exhibits excellent decoupling performance, verifying the versatility and effectiveness of conductive element 12.

[0074] In some embodiments, see Figure 10Each antenna 11 has a first opening 112 communicating with the receiving cavity 111, with two first openings 112 arranged opposite to each other. Each antenna 11 also has a second opening 113 communicating with the receiving cavity 111, the outline of which extends along the length of the antenna 11 to the first opening 112, allowing the conductive element 12 to be inserted into the receiving cavity 111 through the second opening 113. Based on this structure, the following experimental verification is performed:

[0075] Please see Figure 13 A cuboid antenna 11 and a rod-shaped conductive element 12 are used. A portion of one side surface and one bottom or top surface of the antenna 11 are removed to form a second opening 113 and a first opening 112, facilitating the insertion of the rod-shaped conductive element 12 into the receiving cavity 111 through the second opening 113. When the conductive element 12 is located within the receiving cavity 111, it is only surrounded by three sides of the antenna 11. Isolation experiments were conducted for three-sided and four-sided enclosures, and the results are as follows:

[0076] Please see Figure 11 Line e represents the isolation trend line of the antenna 11 in the antenna assembly 1 provided in this embodiment, where only the first opening 112 is provided. Line f represents the isolation trend line of the antenna 11 in the antenna assembly 1 provided in this embodiment, where the first opening 112 and the second opening 113 are provided. Comparing lines e and f, it can be seen that the isolation of the structure in which the conductive element 12 is wrapped on three sides of the antenna 11 is almost the same as that in the structure in which the conductive element 12 is wrapped on four sides of the antenna 11. It can be almost concluded that whether the antenna 11 with only the first opening 112 or the antenna 11 with the second opening 113 and the first opening 112 is used, the isolation of the conductive element 12 inserted into the receiving cavity 111 is basically the same. In other words, in order to facilitate the installation of the conductive element 12, a second opening 113 can be opened on the antenna 11.

[0077] The following is an explanation of the terms used in the above embodiments:

[0078] Isolation refers to the degree of attenuation of the signal transmitted by one antenna 11 and received by another antenna 11. It is usually expressed in dB. The higher the isolation (the larger the negative value), the less interference.

[0079] Radiation efficiency refers to the efficiency with which antenna 11 converts input power into radiated power, reflecting the ability of antenna 11 to effectively convert input power into electromagnetic wave radiation.

[0080] The overall system efficiency refers to the overall efficiency of the antenna system in converting input power into radiation efficiency, taking into account both the radiation efficiency of antenna 11 itself and the impedance matching efficiency between antenna 11 and the signal line.

[0081] The electrical length of antenna 11 refers to the relative length of the signal propagating on antenna 11 at a specific operating frequency. It is usually expressed as a fraction of wavelength (λ) and is used to describe the equivalent length of antenna 11 in the direction of electromagnetic wave propagation.

[0082] The physical length of antenna 11 refers to the actual length of antenna 11.

[0083] This application also provides a terminal that includes the antenna system described in any of the foregoing embodiments. This terminal possesses all the beneficial effects of the aforementioned antenna system, which will not be elaborated upon here. The terminal can be a large, inconveniently movable fixed terminal, or a small mobile terminal, such as a mobile phone or tablet computer. As long as the terminal needs to receive and transmit signals using antenna 11, the antenna system provided in this application can be used, and there is no specific limitation on the type of terminal.
