Description

Technical Field

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

[0002] With the development of electronic device technology, the internal structure of electronic devices is becoming increasingly complex and the layout of components is becoming more compact due to the ever-increasing functions they carry. This leads to a continuous reduction in the clearance area available to the antenna, thus affecting antenna performance. Therefore, there is an urgent need for an electronic device that can miniaturize the antenna to reduce its footprint within the device's internal space while maintaining antenna performance, thereby ensuring the communication capabilities of the electronic device and improving the user experience.

[0003] 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

[0004] To overcome the problems existing in the related technologies, this disclosure provides an electronic device.

[0005] According to a first aspect of the present disclosure, an electronic device is provided, comprising:

[0006] case;

[0007] A metal sheet, comprising a first side, a second side, a third side, and a fourth side connected in sequence, wherein the first side and the second side are electrically connected to the housing so that the housing and the metal sheet constitute a cavity antenna, the third side is configured as the first cavity opening of the cavity antenna, and the fourth side is configured as the second cavity opening of the cavity antenna.

[0008] In some exemplary embodiments, a power supply section is provided on the third side near the fourth side; or, a power supply section is provided on the fourth side near the third side.

[0009] The embodiments disclosed herein further ensure bilateral radiation of the cavity antenna by placing the feed section near the angle between the third and fourth sides of the metal sheet, rather than placing it in the middle of the third or fourth side, thereby ensuring antenna performance.

[0010] In some exemplary embodiments, grounding portions are provided on the first side and the second side.

[0011] The embodiments disclosed herein utilize grounding based on the closed edges of the two cavity antennas, the first and second sides, to effectively control the boundary conditions of the electric field, thereby improving antenna performance.

[0012] In some exemplary embodiments, the length of the third side is positively correlated with the operating wavelength of the cavity antenna.

[0013] The embodiments of this disclosure determine the operating wavelength based on the first operating frequency band, and then determine the length of the third side based on the operating wavelength. Therefore, the first operating frequency band of the cavity antenna can be adjusted by changing the length of the third side, that is, changing the electrical length. Thus, this disclosure can improve the adaptability and adjustability of the cavity antenna.

[0014] In some exemplary embodiments, the length of the third side is equal to the operating wavelength of the cavity antenna.

[0015] The embodiments disclosed herein can minimize the space occupied by the cavity antenna within the electronic device while ensuring antenna performance.

[0016] In some exemplary embodiments, the length of the fourth side is not less than the current amplitude of the cavity antenna.

[0017] The embodiments disclosed herein take current amplitude into account when determining the length of the fourth side, thereby ensuring that the cavity antenna supports the required modes and ensures antenna performance.

[0018] In some exemplary embodiments, both the first side and the second side are electrically connected to a circuit board, the circuit board is electrically connected to the housing, and the circuit board has an opening at the relative position of the metal sheet.

[0019] The embodiments disclosed herein achieve electrical connection between the metal sheet and the housing based on the original circuit board structure in the electronic device, which can avoid occupying more internal area.

[0020] In some exemplary embodiments, the space between the housing and the metal sheet is filled with a target medium, which includes air.

[0021] This disclosure allows the use of air to fill the space between the housing and the metal sheet without the need for other high dielectric constant media. Based on this, the antenna's radiation performance is improved by using a double-sided opening design. Therefore, the embodiments of this disclosure can effectively reduce the design cost of cavity antennas while ensuring antenna performance.

[0022] In some exemplary embodiments, the cavity antenna radiates electromagnetic signals of a first operating frequency band in the direction of the first cavity opening and the direction of the second cavity opening.

[0023] According to the principle of vector superposition, the electromagnetic signal radiated in the direction of the opening of the first cavity and the electromagnetic signal radiated in the direction of the opening of the second cavity in this embodiment can further improve the antenna performance in the oblique upward direction.

[0024] In some exemplary embodiments, the first operating frequency band includes at least one of the following: WIFI (Wireless Fidelity) band, UWB (Ultra-Wideband) band, and millimeter wave band.

[0025] In some exemplary embodiments, the third side and / or the fourth side are positioned near the frame of the electronic device.

[0026] The embodiments disclosed herein further ensure the antenna's outward radiation performance by placing the cavity antenna near the frame.

[0027] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0028] The embodiments disclosed herein can form a cavity antenna with openings on both sides by using a housing and a metal sheet. The antenna design is based on the original housing structure of the electronic device as part of the cavity antenna, which can effectively reduce the space occupied inside the electronic device. Furthermore, the present application forms a two-dimensional radiation aperture by setting two cavity openings and optimizes the electric field distribution. Therefore, the embodiments disclosed herein can ensure antenna performance, thereby ensuring the communication capability of the electronic device and improving the user experience.

[0037] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0038] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples consistent with some aspects of this disclosure as detailed in the appended claims.

[0039] The specific implementation methods of the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0040] Figure 1 This is a schematic diagram illustrating the structure of an electronic device according to an exemplary embodiment of this disclosure. Figure 1 As shown, the electronic device may include: a housing 1 and a metal sheet 2.

[0041] The metal sheet 2 may include a first side 21, a second side 22, a third side 23 and a fourth side 24 connected in sequence. The first side 21 and the second side 22 are electrically connected to the housing 1 so that the housing 1 and the metal sheet 2 form a cavity antenna. The third side 23 is set as the first cavity opening of the cavity antenna, and the fourth side 24 is set as the second cavity opening of the cavity antenna.

[0042] In some embodiments of this disclosure, the housing 1 can be the rear shell of an electronic device. In this case, the rear shell of the electronic device can be made conductive by embedding a metal layer within a plastic rear shell. Alternatively, the housing 1 can be any conductive housing included in the electronic device. This disclosure does not limit the scope of the embodiments.

[0043] It should be noted that, Figure 1 The housing 1 and metal sheet 2 shown are exemplary. Figure 1 It is not used to limit the size of the housing 1 or the ratio between the housing 1 and the metal sheet 2.

[0044] In some embodiments of this disclosure, the metal sheet 2 has a quadrilateral structure, such as a rectangle. The first side 21 and the second side 22 of the metal sheet 2 are two connected sides, and the first side 21 and the second side 22 can be electrically connected to the housing, so that the metal sheet 2 and the housing 1 constitute the resonant cavity structure of the cavity antenna.

[0045] It should be noted that a resonant cavity is a structure capable of storing electromagnetic energy and amplifying the amplitude of electromagnetic waves at a specific frequency. In antenna design, resonant cavities can be used to enhance signal strength at specific frequencies, thereby improving antenna efficiency and gain.

[0046] In addition, the third side 23 and the fourth side 24 of the metal sheet 2 are also two connected sides, and the third side 23 and the fourth side 24 can be set as the cavity opening of the cavity antenna.

[0047] It should be noted that the embodiments of this disclosure construct a cavity antenna with openings on both sides by using a housing and a metal sheet. The antenna design is based on the original housing structure of the electronic device as part of the cavity antenna, which can effectively reduce the space occupied inside the electronic device. Furthermore, this application forms a two-dimensional radiation aperture by setting two cavity openings and optimizes the electric field distribution. Therefore, the embodiments of this disclosure can ensure antenna performance, thereby ensuring the communication capability of the electronic device and improving the user experience.

[0048] In some exemplary embodiments, the cavity antenna radiates electromagnetic signals of a first operating frequency band in the direction of the opening of the first cavity and the direction of the opening of the second cavity.

[0049] In an exemplary embodiment, the cavity antenna, having two cavity openings, can simultaneously radiate signals in the directions of both the first and second cavity openings. Compared to a cavity antenna with only one cavity opening, the embodiments of this disclosure effectively improve the utilization rate of antenna radiation, thereby enhancing antenna performance.

[0050] It should be noted that, according to the principle of vector superposition, the electromagnetic signal radiated in the direction of the opening of the first cavity and the electromagnetic signal radiated in the direction of the opening of the second cavity in this embodiment of the present disclosure can have an enhanced radiation performance in the direction of diagonally upward to the left at 45°. Therefore, by setting two radiation openings, this embodiment of the present disclosure can further improve the antenna performance in the diagonally upward direction.

[0051] For example, Figure 2 A schematic diagram of the radiation direction of a cavity antenna provided in an embodiment of this disclosure is shown. Figure 2As shown, a first cavity opening is provided at the third side 23, which can radiate electromagnetic signals of the first operating frequency band in the direction indicated by arrow a. A second cavity opening is provided at the fourth side 24, which can radiate electromagnetic signals of the first operating frequency band in the direction indicated by arrow b. Furthermore, the radiation performance in the direction indicated by arrow c can have a vector superposition effect.

[0052] In some exemplary embodiments, a power supply section 3 is provided on the side of the third side 23 near the fourth side 24; or, a power supply section 3 is provided on the side of the fourth side 24 near the third side 23.

[0053] In an exemplary embodiment, the power supply unit 3 may be disposed near the angle between the third side 23 and the fourth side 24 of the metal sheet 2. For example, the power supply unit 3 may be disposed on the third side 23 near the fourth side 24. Alternatively, the power supply unit 3 may be disposed on the fourth side 24 near the third side 23.

[0054] It should be noted that, Figure 1 The power supply section 3 is located on the fourth side 24 near the third side 23. This is merely an example and is not intended to limit the scope of this disclosure.

[0055] This embodiment of the present disclosure further ensures the bilateral radiation of the cavity antenna by placing the feed part 3 near the angle between the third side 23 and the fourth side 24 of the metal sheet 2, rather than placing it in the middle part of the third side 23 or the fourth side 24, thereby ensuring the antenna performance.

[0056] In some exemplary embodiments, grounding portions 4 are provided on the first side 21 and the second side 22.

[0057] In some possible implementations, since both the first side 21 and the second side 22 are electrically connected to the housing 1, and the housing 1 can be electrically connected to the ground plane layer of the motherboard, the cavity antenna can be grounded through the first side 21 and the second side 22.

[0058] It should be noted that, in this embodiment of the present disclosure, grounding is achieved by using the closed sides of the cavity antenna, namely the first side 21 and the second side 22, which can effectively control the boundary conditions of the electric field and thus improve the antenna performance.

[0059] In some exemplary embodiments, the length of the third side 23 is positively correlated with the operating wavelength of the cavity antenna.

[0060] In an exemplary embodiment, the length of the third side 23 may be equal to the operating wavelength of the cavity antenna, or it may be equal to half the operating wavelength of the cavity antenna.

[0061] It should be noted that, in order to achieve the miniaturization of the antenna design, the size of the metal piece needs to be kept as small as possible. For example... Figure 1 As shown, if the length of the third side 23 is small, it will affect the radiation aperture of the cavity antenna in the direction of the first cavity opening. Therefore, this embodiment of the present disclosure provides a second cavity opening, so that the cavity antenna can radiate simultaneously based on the first cavity opening and the second cavity opening, effectively increasing the radiation performance of the antenna.

[0062] In an exemplary embodiment, the operating wavelength of the cavity antenna can be determined based on the median frequency of the first operating frequency band. The formula for calculating the operating wavelength is shown in formula (1) below.

[0063] λ=c / f (1)

[0064] In formula (1), f can represent the median frequency of the first working frequency band, c can represent the speed of light, and λ can represent the working wavelength.

[0065] In an exemplary embodiment, taking the first operating frequency band as the WIFI frequency band as an example, its frequency band range can be 5.15GHz to 5.85GHz. The median frequency point, i.e. 5.5GHz, is taken to calculate the operating wavelength, thereby obtaining the operating wavelength of the cavity antenna.

[0066] This disclosure does not limit the first operating frequency band. In some exemplary embodiments, the first operating frequency band includes at least one of the WIFI band, UWB band, and millimeter wave band.

[0067] It should be noted that, in this embodiment, the operating wavelength is determined based on the first operating frequency band, and then the length of the third side 23 is determined according to the operating wavelength. Therefore, the first operating frequency band of the cavity antenna can be adjusted by changing the length of the third side 23, that is, by changing the electrical length. Thus, this disclosure can improve the adaptability and adjustability of the cavity antenna.

[0068] In some exemplary embodiments, the length of the third side 23 may be equal to the operating wavelength of the cavity antenna.

[0069] For example, Figure 3 This diagram illustrates the current distribution of a cavity antenna according to an embodiment of the present disclosure. This cavity antenna can be used as... Figure 1 The cavity antenna shown includes two cavity openings, one in the positive y-axis direction and the other in the negative x-axis direction. Figure 4 A current distribution diagram for another cavity antenna is shown. Figure 4 The cavity antenna shown is a resonant cavity structure with one open side and three closed sides, and the cavity opening direction is the positive y-axis direction.

[0070] like Figure 3 , Figure 4 As shown, the horizontal axis of the current distribution graph represents the period, and the vertical axis represents the amplitude. It can be seen that the current amplitude is largest in the y-direction (A), and smallest at y=0. In the positive x-axis direction, the current follows a normal distribution with a period of T. Figure 3 The cavity antenna shown is Figure 4 A comparison with the cavity antennas shown reveals that... Figure 3 The lateral dimension of the cavity antenna, that is, the length of the third side 23, is less than... Figure 4 The lateral dimensions of the cavity antenna are shown. Additionally, Figure 3 The longitudinal dimension of the cavity antenna, that is, the length of the fourth side 24, is equal to Figure 4 The longitudinal dimension of the cavity antenna is shown.

[0071] It should be noted that, according to the characteristics of electromagnetic field distribution, within one period T, the antenna performance of the cavity antenna is the same as the radiation capability formed by a multi-period current distribution. For example, this period T can be inversely proportional to the median frequency of the first operating frequency band mentioned above, and the operating wavelength can be calculated based on the median frequency of the first operating frequency band, and this operating wavelength can be directly used as the lateral length of the cavity antenna.

[0072] Therefore, due to Figure 3 The lateral dimension of the cavity antenna shown can satisfy one period, therefore this disclosure can minimize the cavity antenna's footprint within the electronic device's internal space while ensuring antenna performance. Figure 3 , Figure 4 Taking the two cavity antennas shown as examples, Figure 3 The lateral dimension of the cavity antenna shown is compared to Figure 4 The cavity antenna shown has its lateral dimension reduced at the position where the current amplitude is 0, and the lateral dimension can be reduced by about 50% in the end.

[0073] In some exemplary embodiments, the length of the fourth side 24 is not less than the current amplitude of the cavity antenna.

[0074] In an exemplary embodiment, the length of the fourth side 24 can be determined based on the current distribution diagram of the cavity antenna. For example, Figure 3 A current distribution diagram of a cavity antenna provided in an embodiment of this disclosure is shown. Figure 3 In the diagram, the vertical axis of the current distribution represents the amplitude. It can be seen that the maximum amplitude of the current in the y-direction is A, and the length of the fourth side 24 of the cavity antenna is greater than the current amplitude of the cavity antenna.

[0075] It should be noted that the embodiments of this disclosure take into account the current amplitude when determining the length of the fourth side 24, thereby ensuring that the cavity antenna supports the required modes and ensures antenna performance.

[0076] In some exemplary embodiments, the first side 21 and the second side 22 are both electrically connected to a circuit board, which is electrically connected to the housing 1, and the circuit board has an opening at the relative position of the metal sheet 2.

[0077] In an exemplary embodiment, the metal sheet 2 can be disposed above the circuit board and fixed to the circuit board by the first side 21 and the second side 22. The metal sheet can be bent downward by the first side 21 and the second side 22 to achieve connection with the circuit board. In addition, the circuit board can be disposed above the housing 1 and connected to the housing 1, so the metal sheet 2 can achieve electrical connection with the housing 1.

[0078] In an exemplary embodiment, the circuit board has an opening at a relative position to the metal sheet 2, which can also be understood as the projection area of ​​the metal sheet 2 on the circuit board. This opening is the interior of the resonant cavity, and the circuit board opens at this position, allowing the interior of the cavity to be filled by a target medium.

[0079] It should be noted that the embodiments disclosed herein achieve electrical connection between the metal sheet and the housing based on the original circuit board structure in the electronic device, which can avoid occupying more internal area.

[0080] In some exemplary embodiments, the space between the housing 1 and the metal sheet 2 is filled with a target medium, which includes air.

[0081] In an exemplary embodiment, the target medium inside the resonant cavity is primarily used to adjust the resonant frequency, optimize the electromagnetic field distribution, and control energy loss. Depending on the specific application requirements, different materials can be selected as the target medium, such as air, ceramics, plastics, or other composite materials.

[0082] In one embodiment, the present disclosure can use air to fill the space between the housing 1 and the metal sheet 2 without using other high dielectric constant media. Based on this, the radiation performance of the antenna is improved by the design of double-sided openings. Therefore, the embodiments of the present disclosure can effectively reduce the design cost of cavity antennas and ensure antenna performance.

[0083] In some exemplary embodiments, the third side 23 and / or the fourth side 24 are positioned near the edge of the electronic device.

[0084] Figure 5 A schematic diagram of the structure of an electronic device provided in an embodiment of this disclosure is shown, such as... Figure 5 As shown, the cavity antenna can be located slightly to the left of the top center of the electronic device, with the third side 23 close to the top frame 5 of the electronic device, thus enabling the cavity antenna to... Figure 5The electronic device shown radiates signals from its top and left side. It should be noted that... Figure 5 This is just an example and is not intended to limit the location of the cavity antenna.

[0085] In other embodiments, the cavity antenna may be located on the left side of the electronic device, with the fourth side 24 close to the left edge of the electronic device. Alternatively, the cavity antenna may be positioned at the upper left corner of the electronic device, such that the third side 23 is close to the upper edge of the electronic device and the fourth side 24 is close to the left edge of the electronic device.

[0086] In some embodiments, the metal piece 2 in the cavity antenna can be electrically connected to the housing 1 via a circuit board, so the position of the cavity antenna can be set with reference to the position of the circuit board.

[0087] It should be noted that, in this embodiment of the invention, placing the cavity antenna near the frame can further ensure the antenna's outward radiation performance.

[0088] It should be noted that, for example, electronic devices can be mobile phones, tablets, e-readers, MP3 players, MP4 players, laptops, in-vehicle systems or desktop computers, portable terminals, laptop terminals, desktop terminals, action cameras, drones, monitor cameras and similar products.

[0089] It should be noted that the electronic device in this embodiment can be a foldable electronic device or a flat-screen electronic device (non-foldable electronic device). In one possible implementation, the electronic device is a foldable electronic device, and the cavity antenna can be arranged on either the first body or the second body connected by a hinge, for example, on the top of the first body. In another possible implementation, the electronic device is a flat-screen electronic device, and the cavity antenna is located on the top of the electronic device.

[0090] It should be noted that the structure of the metal sheet 2 can be similar to that of the shielding cover. This shielding cover can be installed on the circuit board of an electronic device to surround sensitive circuits or interference-generating components, thereby reducing electromagnetic interference between different components. Furthermore, the shielding cover can be provided with protrusions and / or recesses to improve its structural stability.

[0106] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[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 device in use or operation. For example, if the 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 device, the term “above” encompasses both above and below orientations. 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] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0109] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding the specification and drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term “including.”

[0110] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the solutions 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.

[0111] 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.
