Description

Technical Field

[0001] This application relates to the technical field of antennas, and particularly to an electronic device. Background Art

[0002] With the wide application of the fifth-generation mobile communication technology (5G) and satellite communication technology in mobile terminals, mobile terminals need to be equipped with more and more antennas. Generally, antennas need to be arranged in areas with relatively open field patterns such as the frame. However, in order to meet the appearance requirements such as a large display screen and an extremely narrow frame, the structural form of mobile terminals will become more and more complex and changeable, such as a foldable structure. The available space for antenna layout is getting smaller and smaller, which poses a great challenge to the design of the overall antenna scheme of the mobile terminal. It can be seen that there is a problem of insufficient antenna layout space in mobile terminals in the related art. Summary of the Invention

[0003] This application provides an electronic device, which is beneficial to alleviating the problem of insufficient antenna layout space in the electronic device.

[0004] In a first aspect, this application provides an antenna, which includes a metal decorative ring, a non-metal decorative ring, and a circuit board. The metal decorative ring is installed on the non-metal decorative ring. One end face of the non-metal decorative ring facing the metal decorative ring includes a first region. There is a gap between the first region and the metal decorative ring. An antenna radiation component is provided in the first region, and the antenna radiation component is spaced apart from the metal decorative ring, and the antenna radiation component is coupled to the metal decorative ring;

[0005] The circuit board is electrically connected to the antenna radiation component, and the operating frequency band of the antenna radiation component is different from that of the metal decorative ring.

[0006] In the embodiments of this application, by arranging the antenna radiation component in the non-metal decorative ring, and making the antenna radiation component coupled to the metal decorative ring, and the circuit board is electrically connected to the antenna radiation component. In this way, by deploying the antenna in the decorative ring of the electronic device, it is beneficial to improve the space utilization rate. At the same time, the decorative ring antenna can radiate both through the antenna radiation component and through the metal decorative ring. And because the operating frequency band of the antenna radiation component is different from that of the metal decorative ring, in this way, the decorative ring antenna can cover different operating frequency bands, which is beneficial to reducing the number of antennas required to be deployed in the electronic device, and thus is beneficial to alleviating the problem of insufficient antenna layout space in the electronic device.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application belong to the scope of protection of the present application.

[0018] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same category, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0019] The following will combine the accompanying drawings to provide a detailed description of an electronic device provided by an embodiment of this application through specific embodiments and their application scenarios.

[0020] Please refer to Figures 1 to 3 , an embodiment of this application provides an electronic device, including: a metal decorative ring 100, a non-metal decorative ring 200, and a circuit board 300. The metal decorative ring 100 is installed on the non-metal decorative ring 200. One end face of the non-metal decorative ring 200 facing the metal decorative ring 100 includes a first region 201. There is a gap between the first region 201 and the metal decorative ring 100. An antenna radiation component 400 is provided in the first region 201, and the antenna radiation component 400 is spaced from the metal decorative ring 100, and the antenna radiation component 400 is coupled to the metal decorative ring 100;

[0021] The circuit board 300 is electrically connected to the antenna radiation component 400, and the operating frequency band of the antenna radiation component 400 is different from that of the metal decorative ring 100.

[0022] The above antenna radiation component 400 can be used as the radiation structure of the decorative ring antenna. The metal decorative ring 100 and the non-metal decorative ring 200 can jointly form various types of decorative rings in the electronic device. For example, they can be used as the camera decorative ring, etc. Please refer to Figure 1 , when the metal decorative ring 100 and the non-metal decorative ring 200 jointly form a camera decorative ring, a camera lens 500 can be provided in the metal decorative ring 100. At the same time, the non-metal decorative ring 200 can be stacked with the battery cover 600 in the electronic device.

[0023] Among them, the electronic device can be various types of mobile terminals such as mobile phones and tablet computers.

[0024] Please refer to Figure 2, in some embodiments of the present application, the above-mentioned first region 201 may be a recessed region in one of the non-metal decorative ring 200 and the metal decorative ring 100. By providing a recessed first region 201 on the end face of the non-metal decorative ring 200 facing the metal decorative ring 100, in this way, a gap can be formed between the first region 201 and the metal decorative ring 100, and further, the antenna radiation component 400 disposed in the first region 201 can be spaced apart from the metal decorative ring 100.

[0025] In addition, in some other embodiments of the present application, in order to form a gap between the first region 201 and the metal decorative ring 100, the region of the metal decorative ring 100 opposite to the first region 201 may also be set as a recessed region. In this way, a gap can also be formed between the first region 201 and the metal decorative ring 100.

[0026] In some other embodiments of the present application, while setting the first region 201 as a recessed region, the region of the metal decorative ring 100 opposite to the first region 201 may also be set as a recessed region. In this way, the gap between the first region 201 and the metal decorative ring 100 can be further increased, thereby facilitating the setting of the above-mentioned antenna radiation component 400 in the first region 201.

[0027] The above-mentioned circuit board 300 may be the main board of the electronic device, or may also be a circuit board 300 specially matched with the antenna. Please refer to Figure 5 , in some embodiments of the present application, the circuit board 300 reuses the main board in the electronic device, and the circuit board 300, the non-metal decorative ring 200 and the metal decorative ring 100 are stacked in sequence.

[0028] The above-mentioned antenna radiation component 400 may include antenna traces processed in the non-metal decorative ring 200 through processing techniques such as etching, printing, laser engraving electroplating, etc. Or, the antenna radiation component 400 may also include antenna traces manufactured using the flexible printed circuit (FPC) process. Or, the antenna radiation component 400 processed by other processes capable of designing antenna traces on the decorative ring or the main board bracket may also be adopted.

[0029] The electrical connection between the above-mentioned circuit board 300 and the antenna radiation component 400 may include: the feeding circuit in the circuit board 300 is electrically connected to the antenna radiation component 400. In this way, the antenna radiation component 400 can access the antenna signal through the feeding circuit.

[0030] During the operation of the above-described decorative ring antenna, the antenna radiation component 400 can be used as the main radiator, or the metal decorative ring 100 can be used as the main radiator to achieve the switching of the operating frequency band. When the antenna radiation component 400 is used as the main radiator, after receiving the feeding signal fed from the circuit board 300, the antenna radiation component 400 radiates. Correspondingly, when the metal decorative ring 100 is used as the main radiator, after receiving the feeding signal fed from the circuit board 300, the received antenna signal is coupled to the metal decorative ring 100, and the metal decorative ring 100 radiates.

[0031] It can be understood that the operating frequency band of the above-described antenna radiation component 400 and the operating frequency band of the metal decorative ring 100 can be set as needed. For example, in some embodiments of the present application, the operating frequency band of the antenna radiation component 400 and the operating frequency band of the metal decorative ring 100 can include the frequency bands in the following frequency bands: 2G / 3G / 4G / 5G and other cellular communications defined by the 3rd Generation Partnership Project (3GPP), Wireless Fidelity (WIFI), and Global Positioning System (GPS) operating frequency bands.

[0032] In this embodiment, by arranging the antenna radiation component 400 in the non-metal decorative ring 200 and coupling the antenna radiation component 400 with the metal decorative ring 100, and electrically connecting the circuit board 300 with the antenna radiation component 400. In this way, by deploying the antenna in the decorative ring of the electronic device, it is beneficial to improve the space utilization rate. At the same time, the decorative ring antenna can radiate either through the antenna radiation component 400 or through the metal decorative ring 100. And because the operating frequency band of the antenna radiation component 400 is different from the operating frequency band of the metal decorative ring 100, in this way, the decorative ring antenna can cover different operating frequency bands, which is beneficial to reducing the number of antennas required to be deployed in the electronic device, and further beneficial to alleviating the problem of insufficient antenna layout space in the electronic device.

[0033] Optionally, the first region is an annular region, and the orthographic projection of the first region 201 in the metal decorative ring 100 is located within the metal decorative ring 100.

[0034] It can be understood that the antenna radiation component 400 can be disposed on the side of the non-metal decorative ring 200 facing the metal decorative ring 100, and the antenna radiation component 400 is disposed opposite to the non-metal decorative ring 200.

[0035] In this embodiment, since the first region is an annular region, and the orthographic projection of the first region 201 in the metal decorative ring 100 is located within the metal decorative ring 100, the facing area between the antenna radiation component 400 located in the first region 201 and the metal decorative ring 100 can be increased, thereby improving the coupling effect between the antenna radiation component 400 and the metal decorative ring 100. In this way, during the operation with the metal decorative ring 100 as the main radiator, the transmission loss of the antenna signal between the antenna radiation component 400 and the metal decorative ring 100 can be reduced.

[0036] Optionally, the antenna radiation component 400 includes a first radiator 410 in an arc shape. The first radiator 410 faces the metal decorative ring 100, and the first radiator 410 is coupled to the metal decorative ring 100.

[0037] The first radiator 410 includes a first feeding point 411. The circuit board 300 includes a first feeding circuit. The first feeding circuit is electrically connected to the first feeding point 411. The operating frequency band of the first radiator 410 is a first frequency band, and the operating frequency band of the metal decorative ring 100 is a second frequency band. The first frequency band and the second frequency band are different frequency bands.

[0038] Please refer to Figure 3 , the antenna may further include a first feeding elastic sheet 480. The first feeding circuit may be electrically connected to the first feeding point 411 through the first feeding elastic sheet 480. Please refer to Figure 3 , when the first radiator 410 and the first feeding circuit are arranged at intervals, an extension trace 470 may extend from the first feeding point 411 to the side of the first feeding circuit. The first feeding circuit is electrically connected to the first feeding point 411 through the first feeding elastic sheet 480 and the extension trace 470 in sequence. Among them, the first feeding circuit may be various radio frequency circuits in the antenna.

[0039] Among them, the frequency ranges of the first frequency band and the second frequency band can be set as needed. For example, the first frequency band and the second frequency band may include frequency bands in the following frequency bands: cellular communications such as 2G / 3G / 4G / 5G defined by 3GPP, and operating frequency bands of wireless fidelity WIFI / global positioning system GPS.

[0040] In this embodiment, by making the antenna radiation component 400 include a first radiator 410 in an arc shape, the first radiator 410 faces the metal decorative ring 100, and the first radiator 410 is coupled to the metal decorative ring 100. In this way, it is beneficial to improve the coupling effect between the first radiator 410 and the metal decorative ring 100. At the same time, since the operating frequency band of the first radiator 410 is the first frequency band and the operating frequency band of the metal decorative ring 100 is the second frequency band, and the first frequency band and the second frequency band are different frequency bands, in this way, the antenna can cover different operating frequency bands, which is beneficial to reducing the number of antennas required to be deployed in the mobile terminal, and further beneficial to alleviating the problem of insufficient antenna layout space in the mobile terminal.

[0041] Optionally, the antenna radiation component 400 further includes a second radiator 420 in an arc shape. The second radiator 420 faces the metal decorative ring 100, and the second radiator 420 is coupled to the metal decorative ring 100;

[0042] The second radiator 420 includes a tuning point 421. The circuit board 300 further includes a tuning circuit, and the tuning circuit is electrically connected to the tuning point 421.

[0043] Please refer to Figure 4 and Figure 5 , the antenna may further include an antenna tuning shrapnel 490, and the tuning point 421 may be electrically connected to the tuning circuit through the antenna tuning shrapnel 490. Among them, the tuning circuit may be a tuning circuit composed of various tuning devices, and among them, the tuning devices may include components such as an antenna switch and a tunable capacitor.

[0044] As Figure 9 shown, the resonance frequency point of the first radiator 410 is a, the resonance frequency point of the metal decorative ring 100 excited by the coupling of the first radiator 410 is b, and the resonance frequency point of the third radiator 430 is c. By software controlling the parameters of the tuning devices in the tuning circuit, the resonance frequency points a and b can be changed, so that the antenna can cover more operating frequency bands. As Figure 10 shown, by changing the parameters of the tuning devices, the resonance frequency point a is offset to a1, a2, and a3 respectively, so that the problem of narrow bandwidth caused by poor clearance in the decorative ring area can be solved, and more operating frequency bands can be covered.

[0045] In this embodiment, since the second radiator 420 is coupled to the metal decorative ring 100 and the second radiator 420 is electrically connected to the tuning circuit, the resonant frequency point of the metal decorative ring 100 can be controlled by software based on the second radiator 420 and the tuning circuit, so that the metal decorative ring 100 can cover more operating frequency bands other than the second frequency band, thereby further increasing the number of operating frequency bands that the antenna can cover. In this way, when the antenna is used as a decorative ring of a mobile terminal, it is beneficial to further reduce the number of antennas to be deployed in the mobile terminal, and thus beneficial to further alleviate the problem of insufficient antenna layout space in the mobile terminal.

[0046] Optionally, a first gap 440 is provided between the first radiator 410 and the second radiator 420, and the first radiator 410 and the second radiator 420 are coupled through the first gap 440.

[0047] Please refer to Figure 3 , the first radiator 410 and the second radiator 420 can be arranged at intervals along the above-mentioned circular region, that is, the first radiator 410 and the second radiator 420 are located in different circular arc segments in the same circular arc region.

[0048] In this embodiment, since a first gap 440 is provided between the first radiator 410 and the second radiator 420, and the first radiator 410 and the second radiator 420 are coupled through the first gap 440, the resonant frequency point of the first radiator 410 can be controlled by software based on the second radiator 420 and the tuning circuit, so that the first radiator 410 can cover more operating frequency bands other than the first frequency band, thereby further increasing the number of operating frequency bands that the antenna can cover. In this way, when the antenna is used as a decorative ring of a mobile terminal, it is beneficial to further reduce the number of antennas to be deployed in the mobile terminal, and thus beneficial to further alleviate the problem of insufficient antenna layout space in the mobile terminal.

[0049] Optionally, the first radiator 410 is connected to the second radiator 420.

[0050] Please refer to Figure 8 , in some embodiments of the present application, the first radiator 410 and the second radiator 420 are located in different circular arc segments in the same circular arc region, and the first radiator 410 and the second radiator 420 can be directly connected.

[0051] In this embodiment, in order to meet some tuning requirements, such as tuning multiple resonant points in the Ultra High Frequency (UHF) band at the same time, by connecting the first radiator 410 and the second radiator 420, thus, relative toFigure 6 In the illustrated embodiment, by coupling through the first break 440, the tunable range is relatively wider, and the resonant frequencies of the low, medium, and high frequency bands within the UHF band can be tuned, thereby improving the tuning effect in specific scenarios such as UHF.

[0052] Optionally, the antenna radiation component 400 further includes a third radiator 430 in an arc shape. The third radiator 430 faces the metal decorative ring 100, and the third radiator 430 is coupled to the metal decorative ring 100.

[0053] The third radiator 430 is located between the first radiator 410 and the second radiator 420, and there is a second break 450 between the third radiator 430 and the second radiator 420, and a third break 460 between the third radiator 430 and the first radiator 410. The third radiator 430 is coupled to the second radiator 420 through the second break 450, and the third radiator 430 is coupled to the first radiator 410 through the third break 460.

[0054] The third radiator 430 includes a grounding point 431. The third radiator 430 is grounded through the grounding point 431. The third radiator 430 operates in a third frequency band, which is other frequency bands outside the first frequency band and the second frequency band.

[0055] Please refer to Figure 4 and Figure 5 , the antenna may further include an antenna ground spring piece 4110, and the grounding point 431 may be electrically connected to the motherboard reference ground through the antenna ground spring piece 4110.

[0056] Among them, the third radiator 430 can be used as an auxiliary coupling stub of the first radiator 410.

[0057] Please refer to Figure 3 , the first radiator 410, the second radiator 420, and the third radiator 430 can be arranged at intervals along the above-mentioned circular region, that is, the first radiator 410, the second radiator 420, and the third radiator 430 are located in different circular arc segments in the same circular arc region.

[0058] It can be understood that when the third radiator 430 is used as the main radiator, after the first radiator 410 receives the feeding signal fed from the circuit board 300, the received antenna signal is coupled to the third radiator 430, and the third radiator 430 radiates it.

[0059] In addition, in some embodiments of the present application, a first switching circuit may be further added between the tuning point 421 and the circuit board 300. In this way, by controlling the conduction state of the first switching circuit, the length of the radiator actually participating in radiation in the third radiator 430 can be adjusted, so that more antenna frequency bands can be constructed. For example, in some working states, the first switching circuit can be controlled to conduct. At this time, the length of the radiator actually participating in radiation in the third radiator 430 is the segment between the grounding point 431 and the third break 460. In other working states, the first switching circuit can be controlled to be disconnected. At this time, the third radiator 430 is in a suspended state, that is, the grounding point 431 is not grounded. Therefore, the length of the radiator actually participating in radiation in the third radiator 430 is the whole of the third radiator 430.

[0060] In this embodiment, by making the antenna radiation assembly 400 further include an arc-shaped third radiator 430, the third radiator 430 is coupled to the first radiator 410 through the third break 460. In this way, the antenna can cover a third frequency band in addition to the first frequency band and the second frequency band. In addition, since the third radiator 430 is coupled to the second radiator 420 through the second break 450, the resonant frequency point of the third radiator 430 can be controlled by software based on the second radiator 420 and the tuning circuit, so that the third radiator 430 can cover more working frequency bands in addition to the third frequency band, thereby further increasing the number of working frequency bands that the antenna can cover. In this way, when the antenna is used as a decorative ring of a mobile terminal, it is beneficial to further reduce the number of antennas to be deployed in the mobile terminal, and further beneficial to alleviate the problem of insufficient antenna layout space in the mobile terminal.

[0061] In some embodiments of the present application, for Figure 6 the third radiator 430 in the illustrated embodiment, it can also be removed when the number of working frequency bands of the third radiator 430 is small.

[0062] Optionally, the antenna radiation assembly 400 further includes an arc-shaped third radiator 430, the third radiator 430 faces the metal decorative ring 100, and the third radiator 430 is coupled to the metal decorative ring 100;

[0063] The third radiator 430 is located between the first radiator 410 and the second radiator 420, and there is a second break 450 between the third radiator 430 and the second radiator 420. The third radiator 430 is coupled to the second radiator 420 through the second break 450, and the third radiator 430 is spaced apart from the first radiator 410;

[0064] The third radiator 430 includes a second feeding point 432. The circuit board 300 includes a second feeding circuit, and the second feeding circuit is electrically connected to the second feeding point 432. The third radiator 430 operates in a fourth frequency band, and the fourth frequency band is other frequency bands outside the first frequency band and the second frequency band.

[0065] Please refer to Figure 7 , the antenna may further include a second feeding elastic sheet 4120, and the second feeding circuit may be electrically connected to the second feeding point 432 through the second feeding elastic sheet 4120.

[0066] Figure 7 The shown embodiment and Figure 6 The main difference from the shown one is that two antennas are designed using a decorative ring, that is, the first radiator 410 and the third radiator 430 are respectively used as two independent antennas. Among them, the second radiator 420 can be used to tune two antennas or one of them. In addition, since both the first radiator 410 and the third radiator 430 have strong coupling with the metal decorative ring 100, it is necessary to improve the isolation between the two antennas through reasonable design.

[0067] It can be understood that the fourth frequency band in this embodiment may be the same as or different from the third frequency band in the above embodiment, and can be specifically set according to needs.

[0068] In this embodiment, by making the antenna radiation assembly 400 further include an arc-shaped third radiator 430, the third radiator 430 includes a second feeding point 432, and the circuit board 300 includes a second feeding circuit, and the second feeding circuit is electrically connected to the second feeding point 432. In this way, the antenna can cover a fourth frequency band outside the first frequency band and the second frequency band. In addition, since the third radiator 430 is coupled to the second radiator 420 through the second break 450, the resonant frequency point of the third radiator 430 can be controlled by software based on the second radiator 420 and the tuning circuit, so that the third radiator 430 can cover more operating frequency bands outside the fourth frequency band, thereby further increasing the number of operating frequency bands that the antenna can cover. In this way, when the antenna is used as the decorative ring of the mobile terminal, it is beneficial to further reduce the number of antennas required to be deployed in the mobile terminal, and further beneficial to alleviate the problem of insufficient antenna layout space in the mobile terminal.

[0069] Optionally, the second feeding point 432 is opposite to the position of the current zero point of the metal decorative ring 100 during operation.

[0070] Wherein, the position of the current zero point is the high impedance area of the metal decorative ring 100.

[0071] In this embodiment, by making the second feeding point 432 opposite to the position of the current zero point of the metal decorative ring 100 during operation, that is, feeding another antenna at the current zero point position of the metal decorative ring 100, the isolation between the two antennas can be effectively improved.

[0072] Optionally, the metal decorative ring 100 and the non-metal decorative ring 200 are different components of the camera decorative ring.

[0073] In this embodiment, since the metal decorative ring 100 and the non-metal decorative ring 200 are different components of the camera decorative ring, antenna structures with different operating frequency bands can be deployed in the camera decorative ring, thereby realizing the reuse of the camera decorative ring, which is beneficial to improving the space utilization rate of the electronic device.
