[0028] Exemplary embodiments of this disclosure will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. 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.

[0029] The embodiments described below, which are examples of some of the embodiments of this disclosure, do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0030] The specific implementation methods of the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0031] Figure 1 This is a structure of an electronic device according to an exemplary embodiment of the present disclosure. Figure 1 For example, electronic devices can be tablets, mobile phones, 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. Figure 1 As shown, the electronic device includes a metal housing 100 and a conductive cover 200. The conductive cover 200 and the metal housing 100 enclose a resonant cavity with an opening 300.

[0032] In this embodiment of the disclosure, the metal housing 100 can be understood as the metal back cover of an electronic device, or as the back cover housing of an electronic device, wherein the back cover housing is formed by combining the back cover plate and the side frame of the electronic device.

[0033] In this embodiment, the conductive cover 200 can be made of a metallic material such as copper, aluminum, or steel, which possesses both electrical conductivity and a certain supporting strength. The conductive cover 200 has a recess or protrusion on the side away from the metal housing 100. This structural design of the recess or protrusion enhances the deformation resistance of the conductive cover 200.

[0034] The conductive cover 200 and the metal housing 100 enclose a resonant cavity with an opening 300. The conductive cover 200 includes a power supply section 210 and an opening edge 310, wherein the opening edge 310 constitutes the opening 300 of the resonant cavity.

[0035] Figure 2 This is a structure of a conductive shield shown according to an exemplary embodiment of the present disclosure. Figure 1 .like Figure 2 As shown, the opening edge 310 includes at least a first edge 311, a second edge 312, and a third edge 313 that are bent and connected in sequence. The feeding part 210 is disposed on the second edge 312 and is used to feed the conductive cover 200 to excite electromagnetic resonance in the resonant cavity to form a shielded antenna, which can also be called a cavity antenna.

[0036] The power supply unit 210 can be understood as a conductive structure that transmits radio frequency signals from the signal source to the conductive cover 200. The signal source can be located between the circuit board and the conductive cover 200 to generate or process radio frequency signals, and is coupled to the conductive cover 200 through the power supply unit 210 to excite antenna radiation.

[0037] In this embodiment, the first edge 311, the second edge 312, and the third edge 313 are sequentially bent and connected to form a non-linear opening boundary, such as a stepped structure or a Z-shaped structure. The extension directions of the first edge 311 and the third edge 313 are consistent with or approximately parallel to the overall orientation of the opening edge 310, and the second edge 312 is the intermediate bent section between the first edge 311 and the third edge 313.

[0038] For example, the first edge 311 and the third edge 313 can be the two ends of the opening edge 310, and the second edge 312 can be the middle turning segment. The length and angle of the three edges can be adjusted according to the requirements of resonant frequency and radiation direction.

[0039] In this embodiment, the extension directions of the first edge 311 and the third edge 313 are consistent with or approximately parallel to the overall orientation of the opening edge 310. The second edge 312, as the intermediate bend between the first edge 311 and the third edge 313, can be considered to be vertical or inclined relative to the overall orientation of the opening edge 310. The power supply unit 210 is disposed on the second edge 312, and the excitation direction of the power supply signal is approximately perpendicular to the overall orientation of the opening edge 310; this configuration can be defined as a vertical power supply method. Under this power supply method, the current naturally flows upward or downward along the second edge 312, and flows along a broken path to the first edge 311 and the third edge 313 respectively, making the current more concentrated in the opening edge region.

[0040] In related technologies, shielded antennas employ a lateral feeding method, meaning the feed section is positioned parallel to the overall orientation of the opening edge. This method results in a uniform electric field distribution across the shield, leading to a large current inside the shield. Consequently, a significant amount of electromagnetic waves fail to radiate effectively outward, reducing the antenna's radiation efficiency.

[0041] In this embodiment of the electronic device, a conductive cover 200 and a metal housing 100 enclose a resonant cavity with an opening 300. The opening edge 310 of the opening 300 includes at least a first edge 311, a second edge 312, and a third edge 313 that are sequentially bent and connected. The feed section 210 is disposed on the second edge 312, realizing a vertical feed method, which concentrates the current distribution in the opening edge region, thereby efficiently exciting electromagnetic resonance within a limited clearance and improving the radiation efficiency of the antenna. This shielded antenna structure changes the feed method by placing the feed section 210 on the second edge 312, enhancing the directional radiation capability of electromagnetic waves and achieving high-directivity radiation characteristics. It solves the problem of weak directivity and limited performance of shielded antennas in complex electromagnetic environments, and improves communication stability and anti-interference capability.

[0042] In an exemplary embodiment of this disclosure, a first included angle a is formed between the first edge 311 and the second edge 312, and a second included angle b is formed between the second edge 312 and the third edge 313.

[0043] In this embodiment, the values ​​of the first included angle α and the second included angle b are both in the range of 75 degrees to 105 degrees. In a preferred embodiment, the first included angle α can be set to 90 degrees and the second included angle b can also be set to 90 degrees. This ensures that the orientation of the second edge 312 is perpendicular or approximately perpendicular to the overall orientation of the opening edge 310, thereby achieving an efficient vertical power supply method.

[0044] The electronic device of this disclosure, by limiting the first included angle a and the second included angle b to a range of 75 degrees to 105 degrees, especially by selecting an angle close to 90 degrees, can make the direction of the second edge 312 perpendicular or approximately perpendicular to the overall direction of the opening edge 310, thereby realizing a vertical power supply mode, so that the current can flow to the first edge 311 and the third edge 313.

[0045] In an exemplary embodiment of this disclosure, the first length from the power supply section 210 to the first end of the opening edge 310 ranges from 16 mm to 18 mm.

[0046] The first end from the feed section 210 to the opening edge 310 is defined as the feed length section. The first length L1 of the feed length section is limited to a range of 16mm to 18mm, which can effectively excite the 1 / 4λ resonant mode within the operating frequency band, where λ is the wavelength corresponding to the operating frequency band of the shielded antenna.

[0047] In an exemplary embodiment of this disclosure, the second length from the power supply section 210 to the second end of the opening edge 310 ranges from 4 mm to 6 mm.

[0048] The second end from the feed section 210 to the opening edge 310 is defined as the feed short section. The second length L2 of the feed long section is limited to a range of 4mm to 6mm. By setting the feed section 210 at the second edge 312 to achieve vertical feeding, the current is concentrated in the feed short section area. Combined with the overall electromagnetic field distribution characteristics of the shielded antenna, the 1 / 4λ resonant mode of the feed short section can be effectively excited, where λ is the wavelength corresponding to the operating frequency band of the shielded antenna.

[0049] In the electronic device of this disclosure, the feed section 210 is disposed at the second edge 312, and the length of the feed section 210 to both ends of the opening edge 310 is limited, so that both the long feed section and the short feed section are excited to the 1 / 4λ resonant mode, avoiding the situation of reverse cancellation of current, reducing the space occupied by the antenna, and improving the antenna radiation efficiency.

[0050] Figure 3 This is a structure of a conductive shield shown according to an exemplary embodiment of the present disclosure. Figure 2 .like Figure 3 As shown, the opening edge 310 may include a first edge 311, a second edge 312, and a third edge 313, as well as a fourth edge 314 and a fifth edge 315. The fourth edge 314 is connected to the third edge 313, forming a third angle c between them, and a fourth angle d between them.

[0051] In this embodiment, the opening edge 310 includes a first edge 311, a second edge 312, a third edge 313, a fourth edge 314, and a fifth edge 315 that are sequentially bent and connected. By introducing the fourth edge 314 and the fifth edge 315, the opening edge 310 is extended into a more complex bent structure, such as a U-shaped structure. The extending directions of the first edge 311, the third edge 313, and the fifth edge 315 are consistent with or parallel to the overall direction of the opening edge 310, while the second edge 312 and the fourth edge 314 are intermediate bent sections.

[0052] The power supply unit 210 is located at the second edge 312. The excitation direction of the power supply signal is approximately perpendicular to the overall direction of the opening edge 310. This configuration can be defined as a vertical power supply method. After excitation, the current flows along the broken line path to the first edge 311 and the third edge 313, and further flows to the newly added fourth edge 314 and fifth edge 315.

[0053] In this embodiment, the values ​​of the third included angle c between the fourth edge 314 and the third edge 313, and the fourth included angle d between the fourth edge and the fifth edge, are both in the range of 75 degrees to 105 degrees. In a preferred embodiment, the third included angle c can be set to 90 degrees, and the fourth included angle d can also be set to 90 degrees.

[0054] In the electronic device of this disclosure, the opening edge 310 includes a first edge 311, a second edge 312, and a third edge 313, and can also be extended to include a fourth edge 314 and a fifth edge 315 to form a multi-segment bent structure. By adjusting the length and angle of each segment edge, the opening edge 310 can be flexibly set to optimize the current path and electromagnetic wave radiation direction, and efficient radiation can be achieved in a limited space.

[0055] Figure 4 This is illustrated according to an exemplary embodiment of the present disclosure. Figure 2 The diagram shows a three-dimensional structure of the conductive shield. Figure 4 As shown, the conductive cover 200 includes a main body 220 and a bent portion 230. The main body 220 includes an opening edge 310 and a connecting edge 221.

[0056] The bent portion 230 can be formed by bending the connecting edge 221 toward the metal housing 100, and the bent portion 230 is connected to the metal housing 100. The main body 220, the bent portion 230 and the metal housing 100 together form a resonant cavity, and an opening 300 is formed between the opening edge 310 and the metal housing 100.

[0057] In this embodiment of the disclosure, the opening edge 310 of the main body 200 can be understood as the edge of the opening 300 forming the resonant cavity, and the connecting edge 221 of the main body 200 refers to the edges other than the opening edge 310. The connecting edge 221 of the main body 200 is bent toward the metal housing 100 to form a bent portion 230 and is connected to the metal housing 10. The opening edge 310 of the main body 200 has an opening, so that the main body 220, the bent portion 230 and the metal housing 100 are enclosed to form a resonant cavity, and the opening edge 310 and the metal housing 100 form an opening 300.

[0058] For example, such as Figure 4 As shown, the bending portion 230 may include a first bending segment 231 and a second bending segment 232. The first bending segment 231 bends from the main body 220 toward the metal housing 100, and the second bending segment 232 bends from the first bending segment 231 along a direction parallel to the metal housing 100. The second bending segment 232 is connected to the metal housing 100. Thus, the connection between the main body 200 and the metal housing 100 is achieved through the structure of the bending portion 230, and the design of the bending portion increases the flexibility of adjustment. It should be noted that... Figure 4 The bending direction of the second bending segment 232 shown is towards the outside of the cavity. The bending direction of the second bending segment 232 can also be towards the inside of the cavity. This disclosure does not limit this.

[0059] The electronic device of this disclosure includes a conductive cover 200 comprising a main body 220 and a bent portion 230. The bent portion 230 can be integrally formed from the main body 220 by bending, without the need for additional welding or mechanical bending processes. Since the bent portion 230 and the main body 220 are integrally formed, a more complete and continuous conductive path can be achieved, thereby improving the overall electromagnetic enclosure performance of the resonant cavity. This helps reduce electromagnetic energy leakage on the non-radiating opening side and improves the directivity of electromagnetic wave output on the radiating opening side, thus optimizing antenna radiation performance.

[0060] Of course, in other possible implementations, the bending portion 230 can also be implemented using an independent metal bending component, a conductive spring, a riveting structure, or other suitable conductive bending components, as long as the requirements for good electrical conduction and mechanical fixation between the bending portion 230 and the main body portion 220 are met.

[0061] In exemplary embodiments of this disclosure, such as Figure 4 As shown, the power supply section 210 is an extension structure of the main body section 230 formed by bending.

[0062] In this embodiment, the power supply section 210 can be formed by bending and extending the conductive cover 200, forming a continuous conductor with the conductive cover 200 without the need for additional connection processes. This integrated design, by directly bending a specific area of ​​the conductive cover 200 (i.e., the power supply area), achieves signal transmission function while reducing the number of independent parts, lowering assembly costs, and improving structural reliability.

[0063] Of course, in other possible implementations, the power supply unit 210 can also be implemented by means of springs, soldered pins or other power supply connectors, as long as the electrical connection requirements for effectively transmitting the radio frequency signal from the signal source to the conductive cover 200 are met.

[0064] Figure 5 This is a structure of an electronic device according to an exemplary embodiment of the present disclosure. Figure 2 .like Figure 5 As shown, the electronic device may include a metal housing 100, a conductive cover 200, and a circuit board 400. The circuit board 400 is electrically connected to the metal housing 100, and the conductive cover 200 is connected to the side of the circuit board 400 away from the metal housing 100.

[0065] In this embodiment of the disclosure, the metal housing 100 and the circuit board 400 can be connected by welding, or by spring contacts or conductive foam; and the conductive cover 200 and the circuit board 400 can be connected by welding, or by spring contacts or conductive foam. For example, with... Figure 4 Taking the conductive cover 200 shown as an example, the second bent section 232 is connected to the circuit board 400.

[0066] Figure 6 This is a structural diagram of a circuit board according to an exemplary embodiment of the present disclosure. Figure 6 As shown, the circuit board 400 has a cutout area 410, and the conductive cover 200 is connected to the circuit board 400 corresponding to the cutout area 410. The size of the cutout area 410 can be flexibly set according to actual needs.

[0067] For example, the size of the cutout area 410 may be smaller than the size of the conductive cover 200, or the size of the cutout area 410 may be the same as the size of the conductive cover 200. The conductive cover 200 is directly placed over the cutout area 410 and connected to the circuit board 400.

[0068] For example, the size of the cutout area 410 can be larger than the size of the conductive cover 200. The contact point between the conductive cover 200 and the circuit board 400 can be bent outward. A conductive component, such as conductive foam, can be further provided at the contact point between the conductive cover 200 and the circuit board 400 to achieve the connection between the conductive cover 200 and the circuit board 400.

[0069] The electronic device of this embodiment further includes a circuit board 400 electrically connected to a metal housing 100, and a conductive cover 200 connected to the side of the circuit board 400 away from the metal housing 100. The circuit board 400 has a cutout area 410, and the conductive cover 200 is connected to the circuit board 400 corresponding to this area. This design ensures a tight connection between the conductive cover 200 and the circuit board 400, and also allows the conductive cover 200 and the metal housing 100 to enclose a resonant cavity with an opening.

[0070] In exemplary embodiments of this disclosure, such as Figure 6 As shown, the circuit board 400 includes a support plate 420 that extends into the cutout area 410 for electrical connection with the power supply section 210.

[0071] The circuit board 400 also includes a support plate 420 extending into the cutout area 410, which is used to make an electrical connection with the feed section 210 on the conductive cover 200, thereby providing a feed signal to the antenna.

[0072] The electronic device of this disclosure provides a stable and reliable feed signal path for the antenna by providing a support plate 420 extending into the cutout area 410 on the circuit board 400 and electrically connecting the support plate 420 to the feed section 210 on the conductive cover 200.

[0073] In an exemplary embodiment of this disclosure, the electronic device further includes a screen mounted on a metal housing 100, with a conductive shield 200 located between the screen and the metal housing 100. A gap is formed between the screen and the metal housing 100, through which the shielded antenna radiates electromagnetic radiation.

[0074] The electronic device of this disclosure uses the gap between the screen and the metal housing 100 as an antenna radiation channel, without the need for additional openings or changes to the housing structure.

[0075] Figure 7 This is a schematic diagram of the antenna simulation current in an electronic device in related technologies. In these technologies, the shielded antenna uses a lateral feeding method, meaning the feed section is positioned parallel to the overall orientation of the opening edge. From Figure 7 The simulation results show that this lateral feeding method results in a uniform electric field distribution on the shield, which leads to a large current inside the shield. Consequently, many electromagnetic waves fail to radiate effectively outward, reducing the antenna's radiation efficiency.

[0076] Figure 8 This is a schematic diagram illustrating the antenna current simulation of an electronic device according to an exemplary embodiment of the present disclosure. In this embodiment, a conductive cover 200 and a metal housing 100 enclose a resonant cavity with an opening 300. The opening edge 310 of the opening 300 includes at least a first edge 311, a second edge 312, and a third edge 313 that are sequentially bent and connected. A feed section 210 is disposed on the second edge 312, realizing a vertical feed method. Figure 8 The simulation results show that the current is concentrated in the opening edge region A, while the current in the inner region B of the shield is significantly reduced. This indicates that more electromagnetic energy is concentrated in the opening region and radiated outward, thereby improving the antenna's radiation efficiency.

[0077] Figure 9 This is a comparison chart of antenna performance between related technologies and the electronic device implemented in this disclosure. In the related technologies, the shielded antenna uses a horizontal feeding method, while the shielded antenna in the embodiments of this disclosure uses a vertical feeding method. Figure 9 The effect of different feeding methods on radiation efficiency is shown. The horizontal axis represents frequency in GHz, and the vertical axis represents radiation efficiency in dB. From Figure 9 As can be seen, in the frequency range of 5.16GHz to 5.80GHz, the vertical feeding method exhibits higher radiation efficiency at most frequency points, especially near 5.2GHz and 5.8GHz, where its radiation efficiency is significantly better than that of the horizontal feeding method. This indicates that the vertical feeding method can more effectively improve the radiation performance of the antenna, especially in key communication frequency bands.

[0078] In this embodiment of the electronic device, a conductive cover 200 and a metal housing 100 enclose a resonant cavity with an opening 300. The opening edge 310 of the opening 300 includes at least a first edge 311, a second edge 312, and a third edge 313 that are sequentially bent and connected. The feed section 210 is disposed on the second edge 312, realizing a vertical feed method, which concentrates the current distribution in the opening edge region, thereby efficiently exciting electromagnetic resonance within a limited clearance and improving the radiation efficiency of the antenna. This shielded antenna structure changes the feed method by placing the feed section 210 on the second edge 312, enhancing the directional radiation capability of electromagnetic waves and achieving high-directivity radiation characteristics. It solves the problem of weak directivity and limited performance of shielded antennas in complex electromagnetic environments, and improves communication stability and anti-interference capability.

[0079] Furthermore, by limiting the first included angle α between the first edge 311 and the second edge 312, and the second included angle b between the second edge 312 and the third edge 313 to a range of 75 degrees to 105 degrees, especially by selecting an angle close to 90 degrees, the orientation of the second edge 312 can be made perpendicular or approximately perpendicular to the overall orientation of the opening edge 310, thereby enabling a vertical power supply mode, allowing current to flow to the first edge 311 and the third edge 313.

[0080] Furthermore, the feed section 210 is disposed at the second edge 312, and the lengths of the feed section 210 to both ends of the opening edge 310 are limited to between 16mm and 18mm and between 4mm and 6mm, respectively, so that both the long and short feed sections are excited to the 1 / 4λ resonant mode, avoiding the situation of reverse cancellation of current, reducing the space occupied by the antenna, and improving the antenna radiation efficiency.

[0081] 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 practical applications, the position of the conductive components 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 embodiment does not limit this.

[0082] Figure 10 This is a block diagram illustrating an electronic device according to an exemplary embodiment of the present disclosure. (Refer to...) Figure 10 The electronic device 1000 may also include one or more of the following components: a processing component 1002, a memory 1004, a power supply component 1006, a multimedia component 1008, an audio component 1010, an input / output (I / O) interface 1012, a sensor component 1014, and a communication component 1016.

[0083] Processing component 1002 typically controls the overall operation of electronic device 1000, such as operations associated with display, telephone calls, data communication, camera operation, and recording operations.
