Various modifications and changes can be made thereto by those skilled in the art which fall within the scope and spirit of the disclosure.

[0032] The implementations described in some embodiments of the present disclosure below do not represent all implementations consistent with the present disclosure. Instead, they are merely examples consistent with some aspects of the present disclosure as detailed in the appended claims.

[0033] The specific embodiments of the present disclosure will be described below in connection with the drawings.

[0034] Figure 1 is a structural schematic diagram of an electronic device according to an exemplary embodiment of the present disclosure. As shown in Figure 1 , the electronic device can include a first steel sheet group 1, a cavity antenna 2.

[0035] The first steel sheet group 1 is a resonant cavity structure; the cavity antenna 2 is provided with a cavity opening, and the cavity antenna 2 radiates towards the cavity opening; the distance between the cavity antenna 2 and the first steel sheet group 1 is less than a first distance threshold.

[0036] In some possible implementation manners, the first steel sheet group 1 can be a component originally included in the electronic device, and the first steel sheet group 1 can interact with the cavity antenna 2 to improve the antenna performance in addition to performing the original function.

[0037] In an example embodiment, the first steel sheet group 1 can be combined by two steel sheets to form a resonant cavity structure. For example, the two steel sheets forming the first steel sheet group 1 can be steel sheets of the same shape and size. For example, the first steel sheet group 1 can be composed of two rectangular steel sheets, or can also be composed of polygonal, circular or elliptical steel sheets, which are not limited in the embodiments of the present disclosure.

[0038] In addition, the shape and size of the first steel sheet group 1 and the cavity antenna 2 can also be the same or different, which are not limited in the embodiments of the present disclosure.

[0039] It should be noted that the resonant cavity is a structure capable of storing electromagnetic energy and enhancing the amplitude of electromagnetic waves at a specific frequency. In antenna design, the resonant cavity can be used to enhance the signal strength at a specific frequency and improve the efficiency and gain of the antenna.

[0040] The electronic device provided by the embodiments of the present disclosure can form a resonant cavity structure based on the first steel sheet group 1, and can interact with the cavity antenna 2 within the range of the first distance threshold, thereby improving the performance of the cavity antenna 2.

[0041] In some example embodiments of the present disclosure, taking the first steel sheet group 1 as a rectangular shape as an example, the first steel sheet group 1 is combined by two rectangular steel sheets arranged in front of and behind the thickness direction of the electronic device. The two steel sheets are arranged as a resonant cavity structure with three closed sides and one open side, and the three edges of any steel sheet are connected to the corresponding three edges of the other steel sheet to realize closure.

[0042] In some possible implementation manners, a structural schematic diagram of the first steel sheet group 1 provided by the embodiments of the present disclosure can be as shown in Figure 2 .

[0043] The first steel sheet group 1 is combined by two steel sheets overlapping in front and back, and the lengths of the two steel sheets can be equal, and the widths of the two steel sheets can also be equal.

[0044] As shown in Figure 2As shown, the upper side 11 of the first steel sheet group 1 is an open side, and the other three sides 12, 13, and 14 are closed sides. The length of the open side of the first steel sheet group 1 is greater than or equal to the length of the cavity opening of the resonant cavity.

[0045] In some possible embodiments, the first steel sheet group 1 can be provided with extensions at corresponding positions of two steel sheets, respectively, and the three sides can be closed by the corresponding extensions. For example, the first steel sheet group 1 can be closed by means of foam, screws, elastic sheets, grids, or the like.

[0046] In some example embodiments of the present disclosure, the length of the first steel sheet group 1 can be set based on the resonant frequency of the antenna, for example, the resonant frequency of the first steel sheet group 1 can be inversely related to the length of the first steel sheet group 1. In addition, the resonant cavity of the first steel sheet group 1 is configured to support electromagnetic wave radiation of a TE10 mode.

[0047] In example embodiments, the cavity inside the first steel sheet group 1 can be hollow or filled with a target medium, for example, plastic or the like.

[0048] It should be noted that, in the present disclosure, the first steel sheet group 1 is obtained by combining two rectangular steel sheets, without adding extra internal structures of the electronic device, so that the performance of the cavity antenna 2 can be improved by reasonably utilizing the internal metal of the electronic device.

[0049] In some example embodiments of the present disclosure, the cavity antenna 2 is a resonant cavity structure with three closed sides and one open side, wherein the three closed sides of the cavity antenna 2 are grounded.

[0050] In example embodiments, as shown, the open side of the cavity antenna 2 is the upper side 21, and the other three sides 22, 23, and 24 are closed sides. Figure 1

[0051] In example embodiments, the cavity antenna 2 can also be a resonant cavity structure composed of two steel sheets.

[0052] It should be noted that, in other possible embodiments, the cavity antenna 2 can also be a resonant cavity structure with multiple open sides, in which case the radiation direction of the cavity antenna 2 can be determined according to the directions of the multiple cavity openings. The present disclosure does not limit this. In addition, the three closed sides of the first steel sheet group 1 can be grounded or not grounded, and both can achieve the present disclosure.

[0053] In the present disclosure, the cavity antenna 2 is configured as a resonant cavity structure with three closed sides and one open side, so that the radiation direction of the cavity antenna 2 can be determined, and the performance of the cavity antenna 2 can be optimized by the first steel sheet group 1. ​

[0054] In some exemplary embodiments of this disclosure, the distance between the cavity antenna 2 and the first steel sheet group 1 is the distance between the vertex of one side of the opening of the first steel sheet group 1 that is closer to the cavity antenna 2 and the vertex of one side of the opening of the cavity antenna 2 that is closer to the first steel sheet group 1; the first distance threshold is equal to one-quarter of the wavelength of the electromagnetic wave propagating in the medium at the resonant frequency of the first steel sheet group 1.

[0055] In an exemplary embodiment, such as Figure 1 As shown, the distance between the cavity antenna 2 and the first steel sheet group 1 can be the distance between the left vertex of the upper side edge 11 of the first steel sheet group 1 and the right vertex of the upper side edge 21 of the cavity antenna 2. Furthermore, the distance between the cavity antenna 2 and the first steel sheet group 1 can be less than or equal to one-quarter of the wavelength of the electromagnetic wave propagating in the medium at the resonant frequency of the first steel sheet group 1.

[0056] It should be noted that setting the first distance threshold to one-quarter of the wavelength of electromagnetic waves propagating in the medium at the resonant frequency of the first steel sheet group 1 can further improve the resonant superposition effect between the cavity antenna 2 and the first steel sheet group 1, thereby minimizing the performance loss of the cavity antenna 2.

[0057] In an exemplary embodiment, the first distance threshold can be set based on experience or application scenario. The first distance threshold being equal to one-quarter of the wavelength of the electromagnetic wave propagating in the medium at the resonant frequency of the first steel sheet group 1 is a preferred embodiment and is not intended to limit this disclosure.

[0058] It should be noted that when the first distance threshold is greater than one-quarter of the wavelength of electromagnetic waves propagating in the medium at the resonant frequency of the first steel sheet group 1, the cavity antenna 2 and the first steel sheet group 1 can also have a superposition effect, but the effect will be relatively reduced.

[0059] In some exemplary embodiments of this disclosure, the cavity opening direction of the first steel sheet group 1 is the same as or perpendicular to the cavity opening direction of the cavity antenna 2.

[0060] In an exemplary embodiment, Figure 1 The diagram shows a schematic of an electronic device in which the cavity opening direction of the first steel sheet group 1 is the same as the cavity opening direction of the cavity antenna 2.

[0061] according to Figure 1 It can be seen that the cavity openings of both the first steel sheet group 1 and the cavity antenna 2 are upward, that is, pointing outward along the length of the electronic device. Therefore, Figure 1 The cavity opening direction of the first steel sheet group 1 shown is the same as that of the cavity antenna 2, both pointing outward along the length of the electronic device.

[0062] In some possible implementations, the structural schematic diagram of an electronic device provided in this disclosure can be as follows: Figure 3 As shown.

[0063] Among them, the Figure 3 The cavity opening direction of the first steel sheet group 1 shown is perpendicular to the cavity opening direction of the cavity antenna 2. According to... Figure 3 It can be seen that the cavity opening of the first steel plate group 1 faces upwards, that is, it points outwards along the length of the electronic device. The cavity opening of the cavity antenna 2 faces to the right, that is, it points outwards along the width of the electronic device. Therefore, Figure 3 The cavity opening direction of the first steel sheet group 1 shown is perpendicular to the cavity opening direction of the cavity antenna 2.

[0064] In some exemplary embodiments of this disclosure, the cavity opening direction of the first steel sheet group 1 is the same as the cavity opening direction of the cavity antenna 2, and the resonant frequency of the first steel sheet group 1 is the same as the resonant frequency of the cavity antenna 2.

[0065] In one exemplary embodiment, the present disclosure does not limit the values ​​of the resonant frequency of the first steel sheet group 1 and the resonant frequency of the cavity antenna 2. The resonant frequency of the first steel sheet group 1 and the resonant frequency of the cavity antenna 2 can be set based on experience or application scenarios.

[0066] It should be noted that when the cavity opening direction of the first steel plate group 1 is the same as the opening direction of the cavity antenna 2, if the resonant frequency of the first steel plate group 1 is set to be the same as the resonant frequency of the cavity antenna 2, a new resonance can be superimposed on the original resonance of the cavity antenna 2, thereby improving the efficiency of the original resonant position of the cavity antenna 2 and realizing the performance improvement of the cavity antenna 2 in the same frequency band.

[0067] In some exemplary embodiments of this disclosure, the cavity opening direction of the first steel sheet group 1 is the same as the cavity opening direction of the cavity antenna 2, and the resonant frequency of the first steel sheet group 1 is different from the resonant frequency of the cavity antenna 2.

[0068] In an exemplary embodiment, the resonant frequency of the first steel sheet group 1 may be greater than the resonant frequency of the cavity antenna 2, or the resonant frequency of the first steel sheet group 1 may be less than the resonant frequency of the cavity antenna 2. This embodiment does not limit the resonant frequency in this respect.

[0069] It should be noted that when the cavity opening direction of the first steel sheet group 1 is the same as the cavity opening direction of the cavity antenna 2, the resonant frequency of the first steel sheet group 1 is set to be different from the resonant frequency of the cavity antenna 2, and a new resonance can be generated at different frequencies, thereby widening the original resonant bandwidth of the cavity antenna 2 to form a wideband resonance or a double resonance.

[0070] In some possible embodiments, when the difference between the resonant frequency of the first steel sheet group 1 and the resonant frequency of the cavity antenna 2 is less than a preset frequency threshold, a wideband resonance can be formed. When the difference between the resonant frequency of the first steel sheet group 1 and the resonant frequency of the cavity antenna 2 is greater than the preset frequency threshold, a double resonance can be formed. The present disclosure does not limit the value of the preset frequency threshold.

[0071] In some example embodiments of the present disclosure, when the cavity opening direction of the first steel sheet group 1 is perpendicular to the cavity opening direction of the cavity antenna 2, the first steel sheet group 1 can generate a current perpendicular to the cavity opening direction based on the radiation direction of the cavity antenna 2, so as to realize circular polarization of the cavity antenna 2 without additional cost, and the directivity pattern of the cavity antenna 2 can be optimized.

[0072] In addition, the circularly polarized antenna provided by the present disclosure has a simple implementation manner and is more easily applied to a mobile terminal. According to different resonant frequencies, the use experience of Bluetooth and GPS (Global Positioning System) of a user can be improved.

[0073] It should be noted that when the cavity opening direction of the first steel sheet group 1 is perpendicular to the cavity opening direction of the cavity antenna 2, the resonant frequency of the first steel sheet group 1 is set to be the same as the resonant frequency of the cavity antenna 2, and the directivity pattern of the cavity antenna 2 is more circular. When the resonant frequency of the first steel sheet group 1 is set to be different from the resonant frequency of the cavity antenna 2, the directivity pattern of the cavity antenna 2 is more elliptical.

[0074] In some example embodiments of the present disclosure, the electronic device can further include a second steel sheet group.

[0075] For example, the second steel sheet group can be a resonant cavity structure composed of two steel sheets and having three closed sides and one open side, and the distance between the cavity antenna 2 and the second steel sheet group is less than a second distance threshold.

[0076] In example embodiments, the second steel sheet group can have the same shape and size as the first steel sheet group 1. The cavity opening direction of the second steel sheet group can be the same as or perpendicular to the cavity opening direction of the cavity antenna 2. In addition, the resonant frequency of the second steel sheet group can be the same as or different from the resonant frequency of the cavity antenna 2.

[0077] In the example embodiment, when the cavity opening direction of the first steel sheet group 1 is the same as the cavity opening direction of the cavity antenna 2, the cavity opening direction of the second steel sheet group can be the same as or perpendicular to the cavity opening direction of the cavity antenna 2. When the cavity opening direction of the first steel sheet group 1 is perpendicular to the cavity opening direction of the cavity antenna 2, the cavity opening direction of the second steel sheet group can also be the same as or perpendicular to the cavity opening direction of the cavity antenna 2.

[0078] The second distance threshold is not limited in the embodiments of the present disclosure, and can be calculated according to the resonant frequency of the second steel sheet group. For example, when the shape and size of the second steel sheet group are the same as those of the first steel sheet group 1, the second distance threshold can be the same as the first distance threshold.

[0079] It should be noted that, by arranging two steel sheet groups around the cavity antenna 2, the performance of the cavity antenna 2 can be further improved on the basis of the first steel sheet group 1.

[0080] In some possible implementation manners, a structural schematic diagram of an electronic device provided by the embodiments of the present disclosure can be as shown in Figure 4 .

[0081] In this Figure 4 , the electronic device can include a first steel sheet group 1, a cavity antenna 2, and a second steel sheet group 3. The cavity opening direction of the first steel sheet group 1 is the same as the cavity opening direction of the cavity antenna 2. The cavity opening direction of the second steel sheet group 3 is perpendicular to the cavity opening direction of the cavity antenna 2.

[0082] In some example embodiments of the present disclosure, the length of the first steel sheet group 1 is equal to the wavelength of the electromagnetic wave propagating in the medium at the resonant frequency of the first steel sheet group 1, and the length of the first steel sheet group 1 is negatively related to the resonant frequency of the first steel sheet group 1.

[0083] In the example embodiment, the cavity resonance of the first steel sheet group 1 can be in the TE10 mode, and the resonant frequency of the cavity structure can be determined according to the length of the first steel sheet group 1. For example, the relationship between the length of the first steel sheet group 1 and the resonant frequency f0 can be shown in the following formula (1).

[0084]

[0085] In the formula (1), λ ε may represent the length of the first steel sheet group 1, c may represent the speed of light, f0 may represent the resonant frequency, and ε r may represent the dielectric constant of the medium filled in the cavity.

[0086] It should be noted that the embodiment of the present disclosure can achieve the control of the resonant frequency of the first steel sheet group 1 by setting the length of the first steel sheet group 1 based on the wavelength of the electromagnetic wave propagating in the medium at the resonant frequency, thereby achieving the enhancement of the performance of the cavity antenna 2 by the first steel sheet group 1.

[0087] In some example embodiments of the present disclosure, the first steel sheet group 1 is an audio steel sheet group, which is arranged to generate a tone by resonance.

[0088] It should be noted that the audio steel sheet is a thin metal sheet for generating a specific audio frequency, which is commonly used in electronic devices, music boxes, mechanical clocks and some acoustic devices. The audio steel sheet can generate sound by vibration.

[0089] In some example embodiments, a plurality of audio steel sheet groups can be included in the electronic device, for example, by arranging a group of audio steel sheet groups at each R corner inside the electronic device, surround sound of the electronic device can be achieved.

[0090] It should be noted that since the electronic device originally includes a plurality of audio steel sheet groups inside, the embodiment of the present disclosure can utilize the existing audio steel sheet groups inside the electronic device to improve the performance of the cavity antenna 2. Moreover, by limiting the shape, size and position of the audio steel sheet, a new cavity can be constructed without affecting the original function of the audio steel sheet and without adding additional structures to the electronic device, and the resonance mode of the cavity antenna 2 itself is superimposed, thereby effectively improving the antenna performance.

[0091] It should be noted that the electronic device can be a mobile phone, a tablet computer, an e-reader, an MP3 player, an MP4 player, a notebook computer, a car machine or a desktop computer, a portable terminal, a laptop terminal, a desktop terminal, a sports camera, a drone, a monitor camera and the like.

[0092] It should be noted that the electronic device in the embodiment of the present disclosure can be a foldable electronic device, and can be a straight-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 any one of the first body and the second body connected by the rotating shaft, such as being arranged on the top of the first body. In another possible implementation, the electronic device is a straight-screen electronic device, and the cavity antenna is arranged on the top of the electronic device.

[0106] It should be understood that, unless specifically stated and limited otherwise, the terms “joined”, “attached”, “mounted”, “connected”, “linked”, “fixed” and the like used in the embodiments of the present disclosure should be interpreted broadly, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection or communication with each other; can be directly connected, can also be indirectly connected through an intermediate medium, can be internal connection of two elements or interaction relationship between two elements, unless otherwise specifically limited. The specific meaning of the above terms in this document can be understood according to the specific circumstances by those skilled in the art.

[0107] Further, the word "over" used in the context of a component, an element, or a material layer "over" a surface is used herein to mean that the component, element, or material layer is positioned "indirectly" on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the word "over" used in the context of a component, an element, or a material layer "over" a surface can also optionally have a specific meaning: that the component, element, or material layer is positioned "directly" on the surface, e.g., in direct contact with the surface.

[0108] Although terms such as "first", "second", and "third" can be used herein to describe various elements, components, regions, layers or sections, these elements, components, regions, layers or sections are not limited by these terms. Rather, these terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, the first element, component, region, layer or section mentioned in the examples described herein can also be referred to as a second element, component, region, layer or section without departing from the teachings of the examples. In addition, the terms "first", "second" are used for descriptive purposes only and cannot be understood to indicate or imply relative importance or to implicitly specify the number of the technical features indicated. Thus, the features defined with "first", "second" can explicitly or implicitly include at least one of the features. In the description herein, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise explicitly specified.

[0109] It will be understood that the spatially relative terms herein, such as "above", "upper", "below", and "lower", are intended to be interpreted as the relative position of one element to another element as shown in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientations depicted in the figures. For example, if a device in the figures is turned over, elements described as above other element would then be oriented below the other element. Accordingly, the term "above" encompasses both an orientation of above and below. The device can be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative terms used herein interpreted accordingly.

[0110] Furthermore, the word "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 preferred or advantageous over other aspects or designs. Rather, use of the word exemplary is intended to present concepts in a concrete manner. As used in this application, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or". That is, unless specified otherwise, or clear from context, "X employs A or B" is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then "X employs A or B" is satisfied under any of the foregoing instances. In addition, the articles "a" and "an" as used in this application and the appended claims should generally be construed to mean "one or more" unless specified otherwise or clear from context to be directed to a singular form. Thus, use of the articles in this application and the following claims is not limiting.

[0111] Also, although the disclosure has been described with respect to only one or more implementations thereof, those skilled in the art will readily appreciate that other alternatives can be used. It is contemplated that the disclosure can be carried out in other specific ways than those expressly disclosed herein. Any and all such changes, modifications, variations, and improvements that have been or can be made to the present disclosure are intended to be captured by the following claims.

[0112] Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the features of the disclosure disclosed herein. It is intended that the present disclosure be considered as including any and all such variations, modifications, and improvements that have been or can be made to the present disclosure within the scope of the disclosure. The specification and examples given herein are to be considered illustrative and not restrictive. The scope of the disclosure is to be determined by the appended claims.

[0113] It should be understood that the present disclosure is not limited to the precise structures herein described and illustrated and that various modifications and changes can be made without departing from the scope of the present disclosure. The scope of the present disclosure is limited only by the claims that follow.
