Description

Technical Field

[0001] This disclosure relates to the field of electronic equipment technology, and more particularly to an antenna assembly and an electronic device. Background Technology

[0002] With the continuous development of electronic design, more and more electronic devices are equipped with satellite communication capabilities. Because satellites are very far from the ground, the long transmission distance of electromagnetic waves leads to severe signal attenuation. Therefore, to achieve stable satellite communication, mobile phone antennas need to have better performance.

[0003] In related technologies, satellite signal transmission and reception can be achieved by installing a quadruple spiral antenna on an electronic device. Alternatively, the antenna can be mounted on the top bezel of the electronic device. However, while quadruple spiral antennas can achieve directional circularly polarized radiation, their large size makes them inconvenient for integration and installation. Antennas mounted on the top bezel, on the other hand, often only achieve linearly polarized radiation, resulting in poor circular polarization gain and reduced stability of satellite communication.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] To overcome the problems existing in the related technologies, this disclosure provides an antenna assembly and an electronic device.

[0006] According to a first aspect of the present disclosure, an antenna assembly is provided, comprising:

[0007] The radiating part includes at least a first radiator, a second radiator and a third radiator that are bent and connected in sequence, wherein the first radiator and the third radiator are arranged in parallel.

[0008] A frame antenna is coupled to the radiating element via spatial electromagnetic waves, and the current direction of the frame antenna and the current direction of the second radiating element have a first angle.

[0009] In some exemplary embodiments, the frame antenna is arranged parallel to the first radiator, the current direction of the first radiator is consistent with the current direction of the third radiator, and the current direction of the first radiator is the same as or opposite to the current direction of the frame antenna.

[0010] In some exemplary embodiments, the sum of the lengths of the first radiator, the second radiator, and the third radiator is proportional to the operating wavelength of the frame antenna.

[0011] In some exemplary embodiments, the radiating part is disposed on the upper part of the frame antenna, and the distance between the radiating part and the frame antenna is between 5 mm and 10 mm.

[0012] In some exemplary embodiments, the antenna assembly further includes:

[0013] A fixing part is provided for fixing the radiating part to the upper part of the frame antenna.

[0014] In some exemplary embodiments, the dielectric constant of the fixing part is inversely proportional to the sum of the lengths of the first radiator, the second radiator, and the third radiator.

[0015] In some exemplary embodiments, the first end of the third radiator is bent and connected to the second radiator, and the radiating portion further includes at least one radiator that is bent and connected sequentially along the second end of the third radiator. The at least one radiator includes a radiator that is spaced apart from the third radiator, and the spaced radiators are parallel to each other.

[0016] In some exemplary embodiments, the at least one radiator includes a fourth radiator that is bent and connected to the second end of the third radiator, and the fourth radiator includes a current in the same direction as the current in the second radiator.

[0017] In some exemplary embodiments, the first included angle is between 75 degrees and 105 degrees.

[0018] In some exemplary embodiments, the sum of the lengths of the first radiator, the second radiator, and the third radiator is equal to 0.4 to 0.5 times the operating wavelength of the frame antenna.

[0019] According to a second aspect of the present disclosure, an electronic device is provided, the electronic device including the antenna assembly described in any one of the preceding claims.

[0020] In some exemplary embodiments, the antenna assembly is disposed on top of the electronic device.

[0021] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0022] This embodiment of the invention allows for spatial electromagnetic wave coupling between the radiating element and the frame antenna. Since there is a first angle between the current direction of the frame antenna and the current direction of the second radiator, the radiating element can provide a current component perpendicular to the current direction of the frame antenna. This reduces the axial ratio of the antenna radiating towards the sky, increases the circular polarization radiation gain of the antenna, and improves communication stability. Furthermore, the design of the radiating element effectively controls the size of the antenna assembly, facilitating integration and installation.

[0036] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings.

Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure.

Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0037] The embodiments described in the following examples of this disclosure are not intended to represent all embodiments consistent with this disclosure. Rather, they are merely embodiments consistent with some aspects of this disclosure as detailed in the appended claims.

[0038] The specific implementation methods of the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0039] Figure 1 This is a schematic diagram illustrating the structure of an antenna assembly according to an exemplary embodiment of this disclosure. Figure 1 As shown, the antenna assembly 100 may include a radiating part 1 and a frame antenna 2.

[0040] The radiating section 1 includes at least a first radiator 11, a second radiator 12, and a third radiator 13 connected in sequence by bending, with the first radiator 11 and the third radiator 13 arranged in parallel. The frame antenna 2 and the radiating section 1 can be coupled by spatial electromagnetic waves, and there is a first angle between the current direction of the frame antenna 2 and the current direction of the second radiator 12.

[0041] This disclosure does not limit the type of the frame antenna 2. For example, the frame antenna 2 can be a half-wavelength antenna, a quarter-wavelength antenna, an eighth-wavelength antenna, etc. Exemplarily, the frame antenna 2 can be provided with a feed point and a return point, so that the frame antenna 2 can radiate signals based on the corresponding operating frequency band. Exemplarily, the frame antenna 2 can be a satellite antenna, therefore the operating frequency band of the frame antenna 2 can be equal to the corresponding satellite frequency band, such as 1.6 to 2.2 GHz.

[0042] In addition, the radiating part 1 can couple with the frame antenna 2 via spatial electromagnetic waves. Therefore, the radiating part 1 can couple with the energy radiated by the frame antenna 2, thereby generating current.

[0043] It should be noted that the current direction of the frame antenna 2 is parallel to the length direction of the frame antenna 2. The current direction of the first radiator 11 is parallel to the length direction of the first radiator 11. Similarly, the current direction of the second radiator 12 is parallel to the length direction of the second radiator 12, and the current direction of the third radiator 13 is parallel to the length direction of the third radiator 13.

[0044] In some possible embodiments, the radiating part 1 can be made of metal, for example, it can be a one-piece metal strip, which can be bent twice to obtain the first radiator 11, the second radiator 12 and the third radiator 13. Alternatively, the first radiator 11, the second radiator 12 and the third radiator 13 can be three metal strips, and the conductive connection between the first radiator 11 and the second radiator 12, and between the second radiator 12 and the third radiator 13 can be achieved by spot welding or other methods.

[0045] The first radiator 11 and the third radiator 13 are parallel to each other, and the lengths of the first radiator 11 and the third radiator 13 may be the same or different. It should be noted that, in a preferred embodiment, the first radiator 11 and the third radiator 13 have the same length, in which case the second radiator 12 can be located at the middle position in the length direction of the radiating part.

[0046] The antenna assembly 100 provided in this embodiment can be coupled to the frame antenna 2 via spatial electromagnetic waves through the radiating part 1. Since there is a first angle between the current direction of the frame antenna 2 and the current direction of the second radiator 12, the radiating part 1 can provide a current component perpendicular to the current direction of the frame antenna 2, thereby reducing the axial ratio of the antenna radiating towards the sky, improving the circular polarization radiation gain of the antenna, and improving communication stability. Furthermore, the design of the radiating part 1 can effectively control the size of the antenna assembly 100, facilitating integration and installation.

[0047] In some exemplary embodiments, the frame antenna 2 is arranged parallel to the first radiator 11, the current direction of the first radiator 11 is consistent with the current direction of the third radiator 13, and the current direction of the first radiator 11 is the same as or opposite to the current direction of the frame antenna 2.

[0048] It should be noted that the frame antenna 2 is arranged parallel to the first radiator 11, that is, the length direction of the frame antenna 2 is parallel to the length direction of the first radiator 11.

[0049] Figure 2 This is a schematic diagram of the structure of a frame antenna 2 shown in an embodiment of this disclosure. Figure 2As shown, the frame antenna 2 can be a cuboid, with its length parallel to the top edge of the electronic device 200, and the current direction of the frame antenna 2 can be parallel to the top edge of the electronic device 200. Furthermore, the first radiator 11 and the third radiator 13 can also be parallel to the top edge of the electronic device 200. Additionally, in this… Figure 2 In the middle, the frame antenna 2 can be fed through the feed point to form a current parallel to the top edge of the electronic device 200.

[0050] It should be noted that, Figure 2 The frame antenna 2 shown is viewed from a frontal angle, while Figure 1 The frame antenna 1 shown is the result of a top-down view, that is, for Figure 2 From the perspective of the antenna, the radiator 1 is positioned above the frame antenna 2.

[0051] Figure 3 This is a schematic diagram of the structure of an antenna assembly shown in an embodiment of this disclosure. Figure 3 A schematic diagram showing the antenna assembly 100 from a top view is provided. Figure 3 The Z-shaped part is the radiating part 1, and the gray part is the frame antenna 2.

[0052] For example, Figure 3 The arrows in the diagram indicate the current direction of the radiating element 1. The current directions of the first radiator 11 and the third radiator 13 can be parallel to the current direction of the frame antenna, and the current direction of the frame antenna 2 has a first angle with the current direction of the second radiator 12. For example... Figure 2 As shown, the first included angle is 90 degrees.

[0053] It should be noted that the current direction of the first radiator 11 can be the same as or opposite to the current direction of the frame antenna 2. The same current direction can improve the left-hand circular polarization performance of the frame antenna, while the opposite current direction can improve the right-hand circular polarization performance.

[0054] like Figure 1 As shown, the included angle between the first radiator 11 and the second radiator 12 can be a1.

[0055] This disclosure does not limit the angle of a1. For example, the included angle a1 between the first radiator 11 and the second radiator 12 can be in the range of 75 degrees to 105 degrees.

[0056] It should be noted that, in the preferred embodiment, the included angle α1 between the first radiator 11 and the second radiator 12 is 90 degrees, that is, the second radiator 12 is arranged perpendicularly to the first radiator 11 and the third radiator 13 respectively.

[0057] Figure 4 This is a schematic diagram of the structure of a radiating section 1 according to an embodiment of this disclosure. Figure 4 As shown, the included angle α1 between the first radiator 11 and the second radiator 12 is an acute angle.

[0058] Figure 5 This is a schematic diagram of another radiating section 1 shown in an embodiment of this disclosure. For example... Figure 5 As shown, the included angle a1 between the first radiator 11 and the second radiator 12 is an obtuse angle.

[0059] It should be noted that when the included angle α1 between the first radiator 11 and the second radiator 12 is acute or obtuse, the second radiator 12 may have a current component perpendicular to the first radiator 11. This current component can improve the circular polarization gain of the antenna and reduce the axial ratio. If the angle α1 is too large or too small, the current component perpendicular to the first radiator 11 will be small, thereby weakening the effect of improving the circular polarization gain and affecting the antenna performance.

[0060] Taking the radiating part 1 as a bent metal strip as an example, the width of the metal strip is not limited in this embodiment. It should be noted that, with the thickness of the metal strip remaining constant, a wider metal strip will result in less current on the second radiator 12 along the direction perpendicular to the first radiator 11, thereby reducing the circular polarization gain and affecting the antenna performance.

[0061] In some exemplary embodiments, the first included angle may be between 75 degrees and 105 degrees.

[0062] It should be noted that since the first radiator 11 is parallel to the frame antenna 2, the first angle between the frame antenna 2 and the second radiator 12 is equal to the angle between the first radiator 11 and the second radiator 12.

[0063] In some exemplary embodiments, the sum of the lengths of the first radiator 11, the second radiator 12, and the third radiator 13 is proportional to the operating wavelength of the frame antenna 2.

[0064] For example, the length of the first radiator 11 can be L1, the length of the second radiator 12 can be L2, and the length of the third radiator 13 can be L3. Therefore, the sum of L1, L2, and L3 can be proportional to the operating wavelength of the frame antenna 2.

[0065] It should be noted that, as Figure 1 As shown, when the first radiator 11 is perpendicular to the second radiator 12, the length L2 of the second radiator 12 can be approximately equal to the width of the frame antenna 2.

[0066] In some possible implementations, the sum of the lengths of the first radiator 11, the second radiator 12, and the third radiator 13 may be equal to 0.4 to 0.5 times the operating wavelength of the frame antenna 2.

[0067] It should be noted that, since the radiating part 1 needs to resonate near the corresponding satellite frequency band to ensure the circular polarization performance of the radiation, for example, the radiating part 1 can achieve current resonance based on a half-wavelength mode. Therefore, in order for the radiating part 1 to couple energy at the corresponding satellite frequency, the sum of the lengths of the first radiator 11, the second radiator 12 and the third radiator 13 needs to be close to 0.5 times the operating wavelength of the frame antenna 2.

[0068] Based on this, in order to adjust the phase difference between the current in the radiating section 1 and the current in the frame antenna 2 to improve circular polarization performance while ensuring that the radiation direction is towards the sky, the sum of the lengths of the first radiator 11, the second radiator 12, and the third radiator 13 can be correspondingly shortened based on 0.5 times the operating wavelength. Therefore, the sum of the lengths of the first radiator 11, the second radiator 12, and the third radiator 13 can be 0.4 to 0.5 times the operating wavelength of the frame antenna 2.

[0069] For example, if the sum of the lengths of the first radiator 11, the second radiator 12, and the third radiator 13 is greater than 0.5 times the operating wavelength of the frame antenna 2, the radiating section 1 may become a reflector relative to the frame antenna 2, preventing energy from radiating upwards and causing the maximum radiation direction to be towards the ground. Conversely, if the sum of the lengths of the first radiator 11, the second radiator 12, and the third radiator 13 is less than 0.4 times the operating wavelength of the frame antenna 2, the coupling energy of the radiating section 1 will decrease, making it difficult to ensure circular polarization gain.

[0070] It should be noted that the current-coordinated resonance of radiator 1 based on a half-wavelength mode is only one example. Radiator 1 can also achieve resonance based on other modes, and the length of the radiator can be set accordingly based on the corresponding mode. This disclosure does not limit this. In addition, the sum of the lengths of the first radiator 11, the second radiator 12, and the third radiator 13 can also be adjusted according to the corresponding satellite frequency to improve antenna performance.

[0071] In some exemplary embodiments, the radiating part 1 is disposed on the upper part of the frame antenna 2, and the distance between the radiating part 1 and the frame antenna 2 is between 5 mm and 10 mm.

[0072] In an exemplary embodiment, in order to improve the circular polarization performance, the radiating part 1 and the frame antenna 2 need to be spaced at a certain distance. If the distance between the radiating part 1 and the frame antenna 2 is too close, the guiding effect may be weak. In addition, if the distance between the radiating part 1 and the frame antenna 2 is too far, the coupling energy of the radiating part 1 will be reduced, resulting in a decrease in circular polarization gain.

[0073] In one possible implementation, the distance between the radiating part 1 and the frame antenna 2 can be set between 5 mm and 10 mm. In this case, the guiding effect of the radiating part 1 is ensured so that the circularly polarized radiation direction is towards the sky, and the circular polarization gain of the antenna can be maximized.

[0074] In some exemplary embodiments, the antenna assembly 100 provided in this disclosure may further include a fixing part 3, which is used to fix the radiating part to the upper part of the frame antenna.

[0075] For example, the radiating part can be disposed on the fixing part 3 in the form of LDS (Laser Direct Structuring), FPC (Flexible Printed Circuit) or silver paste.

[0076] In some embodiments, the fixing part 3 can be configured as a hollow structure. Additionally, the fixing part 3 can be made of a low-loss material, thereby reducing electromagnetic wave propagation loss and further improving the antenna's circular polarization gain.

[0077] In some exemplary embodiments, the dielectric constant of the fixing part 3 is inversely proportional to the sum of the lengths of the first radiator 11, the second radiator 12, and the third radiator 13.

[0078] For example, in order to achieve the same resonant frequency, the larger the dielectric constant of the fixed part 3, the smaller the sum of the lengths of the first radiator 11, the second radiator 12 and the third radiator 13 need to be.

[0079] In some exemplary embodiments, the first end of the third radiator 13 is bent and connected to the second radiator 12. The radiating part 1 also includes at least one radiator that is bent and connected sequentially along the second end of the third radiator 13. The at least one radiator includes a radiator that is spaced apart from the third radiator 13 and the spaced radiators are parallel to each other.

[0080] Figure 6 A schematic diagram of the structure of a radiating section 1 provided in an embodiment of this disclosure is shown. For example... Figure 6 As shown, the second end of the third radiator 13 can also be bent and connected to at least one radiator in sequence.

[0081] Taking a bent metal strip as an example, the metal strip can be bent twice to obtain a Z-shaped radiating section 1 composed of a first radiator 11, a second radiator 12, and a third radiator 13. In an exemplary embodiment, the metal strip can be bent n times to obtain... Figure 6 The radiating part 1 shown is an integer n greater than 2.

[0082] In some exemplary embodiments, at least one radiator includes a fourth radiator 14 that is bent and connected to the second end of the third radiator, and the fourth radiator 14 includes a current in the same direction as the current in the second radiator.

[0083] In an exemplary embodiment, for the radiating section 1 obtained by bending n times, the current direction on the second radiator 12 and each radiator spaced apart from the second radiator 12 can be adjusted so that the current direction on the second radiator 12 and each radiator spaced apart from the second radiator 12 is in the same direction or mostly in the same direction.

[0084] An exemplary embodiment of this disclosure also provides an electronic device that may include the antenna assembly described above.

[0085] Figure 7 This is a schematic diagram illustrating the structure of an electronic device according to some embodiments of the present disclosure. Figure 7 The left side shows a perspective view of the electronic device 200, the upper right side shows a top view of the electronic device 200, and the lower right side shows a front view of the electronic device 200.

[0086] For example, the antenna assembly 100 may be disposed on the top of the electronic device 200. In an exemplary embodiment, the frame antenna 2 in the antenna assembly 100 may be disposed on the top frame of the electronic device 200, and the radiating part 1 may be disposed on the upper part of the frame antenna 2 by means of the fixing part 3.

[0087] It should be noted that while the frame antenna 2 can radiate upwards towards the electronic device 200, due to the thinness of the electronic device and the small antenna clearance, the axial ratio of the upper half of the electronic device 200 is relatively high, resulting in a low circular polarization radiation gain. This embodiment, by providing the radiating part 1, can provide a current component perpendicular to the current direction of the frame antenna 2, thereby reducing the axial ratio of the antenna radiating towards the sky, effectively improving the circular polarization radiation gain of the antenna, and enhancing communication stability. Furthermore, the design of the radiating part 1 can effectively control the size of the antenna assembly 100, facilitating integration and installation.

[0088] For example, the fixing part 3 can be a protective case or clamp for an electronic device. For instance, such as... Figure 7 As shown, the fixing part 3 can be a protective shell for electronic devices.

[0089] In an exemplary embodiment, Figure 8 A schematic diagram of the structure of another electronic device provided in an embodiment of this disclosure is shown. For example... Figure 8 As shown, Figure 8 The left side shows the radiator 1 mounted on a fixture, while Figure 8The right side shows the radiator 1 being mounted on the electronic device 200 using a clamp.

[0090] It should be noted that the circular polarization gain enhancement effect of the radiator 1 mounted on the fixture is the same as that of the radiator mounted on the protective shell, but mounting the radiator 1 on the fixture can further reduce the size of the electronic device 200.

[0091] It should be noted that, by way of example, the electronic device can be a mobile phone, tablet computer, e-reader, MP3 player, MP4 player, laptop computer, in-vehicle system or desktop computer, portable terminal, laptop terminal, desktop terminal, action camera, drone, monitor camera, and similar products. Furthermore, the electronic device in this embodiment can be a foldable electronic device or a flat-screen electronic device (non-foldable electronic device), and this embodiment does not impose any limitations on this.

[0092] Of course, in practical applications, the position of the antenna assembly can be flexibly adjusted according to factors such as the specific shape, size, internal structure and antenna performance requirements of the electronic device, and this disclosure does not limit this.

[0093] In some exemplary embodiments, a schematic diagram of the circular polarization radiation direction of an electronic device can be as follows: Figure 9 As shown. In this Figure 9 In the image, the left side shows the circular polarization radiation effect without radiator 1, and the right side shows the circular polarization radiation effect with radiator 1. It can be seen that the circular polarization gain is significantly improved after adding radiator 1; the gain in the positive z-axis direction increases from -0.75 dBic (decibels relative to an isotropic radiator with circular polarization) to 3.50 dBic.

[0094] In some exemplary embodiments, the axial ratio direction diagram of an electronic device can be as follows: Figure 10 As shown. In this Figure 10 In the diagram, the left side shows the axial ratio direction without radiator 1, and the right side shows the axial ratio direction after radiator 1 is installed. It can be seen that the axial ratio of the upper half-space is significantly reduced after radiator 1 is installed, with the axial ratio in the positive z-axis direction decreasing from 32.72 dB to 15.58 dB.

For example, the electronic device may be a mobile phone, computer, digital broadcasting terminal, messaging device, game console, tablet device, medical device, fitness equipment, personal digital assistant, etc.

Electronic device 1100 can access wireless networks based on communication standards, such as WiFi, 3G, 4G, 5G, other communication standards, or combinations thereof. In some embodiments of this disclosure, communication component 1116 receives broadcast signals or broadcast-related information from an external broadcast management system via a broadcast channel. In some embodiments of this disclosure, communication component 1116 further includes a near-field communication (NFC) module to facilitate short-range communication. For example, the NFC module may be implemented based on radio frequency identification (RFID) technology, Infrared Data Association (IrDA) technology, ultra-wideband (UWB) technology, Bluetooth (BT) technology, and other technologies.

[0105] In some embodiments of this disclosure, the electronic device 1100 may be implemented by one or more application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors, or other electronic components to perform the methods described above.

[0106] In some embodiments of this disclosure, a non-transitory computer-readable storage medium including instructions is also provided, such as a memory 1104 including instructions, which can be executed by a processor 1120 of an electronic device 1100 to perform the above-described method. For example, the non-transitory computer-readable storage medium may be a ROM, random access memory (RAM), CD-ROM, magnetic tape, floppy disk, and optical data storage device, etc.

[0107] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the electronic device during use or operation. For example, if the electronic device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the electronic device, the term “above” encompasses both above and below orientations. Electronic devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0108] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0109] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
