Description

Technical Field

[0001] The present invention relates to an electronic device and an antenna module, and particularly to an electronic device applicable to three different frequency bands and an antenna module applicable to three different frequency bands. Background Art

[0002] In existing common electronic devices such as smart phones, tablet computers, and notebook computers, in order to perform wireless communication in different frequency bands, relevant manufacturers usually set multiple antennas in these electronic devices, so that the electronic devices can perform wireless communication in different frequency bands through different antennas.

[0003] In practical applications, when the space where antennas can be installed in smart phones, tablet computers, and notebook computers is relatively narrow, relevant manufacturers will face the problem that they cannot install multiple antennas at the same time. Therefore, for relevant manufacturers, how to design an antenna so that the antenna can be installed in an electronic device with a relatively narrow space has become an issue faced by relevant manufacturers.

[0004] Therefore, it is necessary to provide an electronic device and an antenna module to solve the above problems. Summary of the Invention

[0005] The present invention discloses an electronic device and an antenna module, which are mainly used to improve known electronic devices such as smart phones and notebook computers. In order to receive wireless signals in a variety of different frequency band ranges, multiple antennas need to be set. However, in the case where the overall appearance of devices such as smart phones and notebook computers tends to be thinner and lighter, it is not easy for relevant manufacturers to set multiple antennas for receiving different frequency band ranges in devices such as smart phones and notebook computers while maintaining the receiving efficiency of the antennas.

[0006] One embodiment of the present invention discloses an electronic device, which includes: a metal cover and an antenna module. The metal cover has two cover body slots, the two cover body slots are arranged side by side and penetrate the metal cover respectively, and the lengths of the two cover body slots are different. The antenna module includes: a substrate, an antenna structure, and a bottom surface structure. The substrate is disposed on one side of the metal cover, and the substrate has a first side surface and a second side surface opposite to each other. The antenna structure is a conductive structure, the antenna structure is formed on the first side surface, the antenna structure defines a feeding portion, and the antenna structure includes: a first excitation segment, a second excitation segment, and a connecting segment. At least a part of the orthographic projection of the first excitation segment on the metal cover overlaps with one of the cover body slots; at least a part of the orthographic projection of the second excitation segment on the metal cover overlaps with the other cover body slot; the connecting segment connects the first excitation segment and the second excitation segment; the bottom surface structure is conductive and disposed on the second side surface, the bottom surface structure is connected to the antenna structure, and the bottom surface structure is grounded through the substrate; the bottom surface structure has two antenna slots, and the lengths of the two antenna slots are different; wherein, when a signal source feeds the antenna structure through the feeding portion, the antenna structure, one of the antenna slots and one of the cover body slots can generate a first frequency band, the antenna structure, the other antenna slot and the other cover body slot can generate a second frequency band, the antenna structure can generate a third frequency band, and the frequency ranges corresponding to the first frequency band, the second frequency band and the third frequency band are not completely the same as each other.

[0007] One embodiment of the present invention discloses an antenna module for fixedly disposed on a metal cover. The metal cover includes a metal cortical structure and a non-metal inner structure. The metal cortical structure is the outer surface of the metal cover body and covers the non-metal inner structure. The metal cover has two cover body slots, which are arranged side by side and penetrate the metal cover respectively. The lengths of the two cover body slots are different. The antenna module includes a substrate, an antenna structure, and a bottom structure. The substrate is disposed on one side of the metal cover and has a first side and a second side opposite to each other. The antenna structure is a conductive structure formed on the first side. The antenna structure defines a feeding portion and includes a connecting segment, a first excitation segment, and a second excitation segment. The first excitation segment extends from one end of the connecting segment in an extending direction. The second excitation segment extends from the other end of the connecting segment in the extending direction. The bottom structure is conductive and disposed on the second side. The bottom structure is connected to the antenna structure and is grounded through the substrate. The bottom structure has two antenna slots, and the lengths of the two antenna slots are different. Wherein, when the antenna module is fixedly disposed on the metal cover, at least a part of the positive projection of the first excitation segment on the metal cover overlaps with one of the cover body slots, and at least a part of the positive projection of the second excitation segment on the metal cover overlaps with the other cover body slot. When a signal source feeds the antenna structure through the feeding portion, the antenna structure, one of the antenna slots, and one of the cover body slots can generate a first frequency band, the antenna structure, the other antenna slot, and the other cover body slot can generate a second frequency band, and the antenna structure can generate a third frequency band. The frequency ranges corresponding to the first frequency band, the second frequency band, and the third frequency band are not completely the same as each other.

[0008] In summary, for the electronic device and the antenna module of the present invention, through the design of the first excitation segment, the second excitation segment, and the connecting segment of the antenna structure, and in cooperation with the long slot and the short slot of the metal cover, when the signal source feeds the antenna structure through the feeding portion of the antenna structure, the antenna module can generate three frequency bands that are not completely the same. In addition, through the design of the bottom structure, relevant designers can easily adjust the frequency ranges of different frequency bands of the antenna according to the material composition of the metal cover (for example, the metal cover is made of pure metal, or in addition to the metal material, the metal cover is mixed with non-metal materials).

[0088] In the following description, if specific drawings are referred to or as shown in specific drawings, it is only used to emphasize that in the subsequent description, most of the related content mentioned appears in that specific drawing, but it does not limit that only that specific drawing can be referred to in the subsequent description. In the following specification, "coupled" means a connection method including non-direct contact but having direct or indirect conduction to form an electrical connection.

[0089] Please refer to Figures 1 to 4 , Figure 1 which is a partial schematic diagram of the first embodiment of the electronic device of the present invention, Figure 2 which is a partial exploded schematic diagram of the first embodiment of the electronic device of the present invention, Figure 3 which is another partial exploded schematic diagram of the first embodiment of the electronic device of the present invention, Figure 4 which is a cross-sectional schematic diagram of the electronic device of the present invention along the Figure 1 indicated IV-IV section line.

[0090] The electronic device 100 of the present invention includes: a metal cover 1 and an antenna module 2. The electronic device 100 referred to herein can be, for example, a smart phone, a tablet computer, a notebook computer, etc., which is not limited herein; correspondingly, the metal cover 1 can be the upper cover, the back cover, etc. of the electronic device 100, which is not limited herein.

[0091] The metal cover 1 has two cover body slot holes, which are respectively defined as a cover body short slot hole 11 and a cover body long slot hole 12. The cover body short slot hole 11 penetrates through the metal cover 1, and the cover body long slot hole 12 penetrates through the metal cover 1. In practical applications, both the cover body short slot hole 11 and the cover body long slot hole 12 can be closed rectangular through holes, but the outer shapes of the cover body short slot hole 11 and the cover body long slot hole 12 are not limited thereto. The length 11W of the cover body short slot hole 11 is less than the length 12W of the cover body long slot hole 12. The difference between the length of the cover body short slot hole 11 and the length of the cover body long slot hole 12 can vary according to requirements, which is not limited herein.

[0092] In this embodiment, the cover body short slot hole 11 and the cover body long slot hole 12 are arranged side by side, and the short side of the cover body short slot hole 11 and the short side of the cover body long slot hole 12 are arranged close to each other, but the cover body short slot hole 11 and the cover body long slot hole 12 are not limited to being arranged side by side.

[0093] The antenna module 2 includes: a substrate 21, an antenna structure 22, a grounding member 23, and a bottom surface structure 27. The substrate 21 is disposed on one side of the metal cover 1. The antenna structure 22 is a conductive structure, and the antenna structure 22 is formed on one side surface of the substrate 21. In practical applications, the substrate 21 can be, for example, an FR4 (Flame Retardant 4) substrate, a printed circuit board (PCB), a flexible circuit board (FCB), etc., which can be selected according to requirements and are not limited herein; the antenna structure 22 can be a conductive sheet-like structure (such as a copper foil) formed on one side surface of the substrate 21. The two opposite wide side surfaces of the substrate 21 are respectively a first side surface 211 and a second side surface 212. The antenna structure 22 is disposed on the first side surface 211, and the bottom surface structure 27 is disposed on the second side surface 212.

[0094] The antenna structure 22 defines a feeding portion 221, and the feeding portion 221 is used to connect to a signal source, and the signal transmitted by the signal source will be fed into the antenna structure 22 through the feeding portion 221. The antenna structure 22 includes a first excitation segment 222, a second excitation segment 223, and a connection segment 224. The two ends of the connection segment 224 are respectively connected to the first excitation segment 222 and the second excitation segment 223, and the first excitation segment 222, the second excitation segment 223, and the connection segment 224 are integrally formed on the substrate 21. Among them, the first excitation segment 222 can be formed by extending from one end of the connection segment 224 in an extending direction, and the second excitation segment 223 can be formed by extending from the other end of the connection segment 224 in the extending direction, and the first excitation segment 222, the second excitation segment 223, and the connection segment 224 can jointly form a structure similar to an inverted U shape, and the feeding portion 221 is located on the first excitation segment 222.

[0095] In a specific implementation, the grounding member 23 is a conductive structure, and the grounding member 23 is used for grounding. The grounding member 23 includes, for example, a first grounding structure 231, a grounding sheet body 232, and a second grounding structure 233. The first grounding structure 231 and the second grounding structure 233 are formed on the first side surface 211 of the substrate 21. The first grounding structure 231 and the second grounding structure 233 can be respectively disposed adjacent to the first excitation segment 222 and the second excitation segment 223. The first grounding structure 231 and the second grounding structure 233 can respectively present as rectangular sheet bodies. In one practical application, the second grounding structure 233 can be connected to the end of the second excitation segment 223, and the two can be integrally formed.

[0096] The ground plate 232 is coupled to the first ground structure 231 and the second excitation segment 223. In practical applications, the first ground structure 231 and the ground plate 232 may be integrally formed and connected, or the first ground structure 231 and the ground plate 232 may be fixed to each other by soldering with solder, but this is not limited thereto. In practical applications, a part of the ground plate 232 may be fixed to the metal cover 1 by various means.

[0097] As Figure 3 shown, the bottom surface structure 27 is a conductive structure, and the bottom surface structure 27 is connected to the antenna structure 22. The bottom surface structure 27 is grounded through the substrate 21. The bottom surface structure 27 includes two antenna slots. The lengths of the two antenna slots are different, and the two antenna slots are an antenna long slot 271 and an antenna short slot 272 respectively. The antenna long slot 271 and the antenna short slot 272 are independent closed holes respectively. The overall shape of the bottom surface structure 27 may be generally in the shape of an inverted 8, and two antenna slots are formed accordingly.

[0098] As Figure 4 shown, in one specific embodiment, the substrate 21 may include a plurality of through holes 213. Each through hole 213 penetrates the substrate 21, and a conductive structure 214 is filled in each through hole 213. The plurality of through holes 213 may be correspondingly located at the positions of the first ground structure 231 and the second ground structure 233, and the antenna structure 22 and the bottom surface structure 27 may be connected through the plurality of conductive structures 214. The through holes 213 and the conductive structures 214 may be formed together during the manufacturing process of the substrate 21, but this is not limited thereto. Of course, the connection manner between the bottom surface structure 27 and the antenna structure 22 is not limited thereto, and the two may also be connected to each other by other means.

[0099] Regarding the forming manner and the forming sequence of the first ground structure 231, the second ground structure 233, the antenna structure 22, the bottom surface structure 27, the through holes 213, and the conductive structure 214, they can all be designed according to actual needs and are not limited herein. For example, in one embodiment, it may also be that after the antenna structure 22, the bottom surface structure 27, and the grounding member 23 are formed on the substrate 21, the through holes 213 are formed on the first ground structure 231 and the second ground structure 233, and then the conductive structure 214 is formed in the through holes 213.

[0100] It should be noted that in different embodiments, the grounding member 23 may not include the first ground structure 231, and the ground plate 232 is directly connected to the end of the first excitation segment 222, and the ground plate 232 is directly connected to the bottom surface structure 27 through a plurality of conductive structures 214.

[0101] In practical applications, there is a middle cover structure 15 between the two cover body slots, and there is an antenna middle structure 275 between the two antenna slots in the bottom surface structure 27. In practical applications, a first length 15W of the middle cover structure 15 can be approximately the same as a second length 275W of the antenna middle structure 275. The length of the long cover slot 12 is greater than the length of the long antenna slot 271, and the length 11W of the short cover slot 11 is greater than the length 272W of the short antenna slot 272.

[0102] In addition, the height 271H of the long antenna slot 271 and the height 272H of the short antenna slot 272 can be approximately the same. The height 12H of the long cover slot 12 and the height 11H of the short cover slot 11 can be approximately the same. In practical applications, the height 271H of the long antenna slot 271, the height 272H of the short antenna slot 272, the height 12H of the long cover slot 12, and the height 11H of the short cover slot 11 can be approximately the same, but not limited thereto. In different embodiments, the height 271H of the long antenna slot 271 and the height 272H of the short antenna slot 272 can also be slightly higher than the height 12H of the long cover slot 12 and the height 11H of the short cover slot 11.

[0103] As Figure 1 and Figure 4 shown, it should be particularly noted that in one of the embodiments, the metal cover 1 can include a metal cortical structure 16 and a non-metal inner layer structure 17. The metal cortical structure 16 is the outer surface of the metal cover 1 and covers the non-metal inner layer structure 17. For example, the metal cortical structure 16 can be substantially composed of an aluminum-magnesium alloy material, and the non-metal inner layer structure 17 can be substantially composed of a plastic material. That is, the metal cover 1 can be a structure with an aluminum skin and a plastic core. In special embodiments, the non-metal inner layer structure 17 of the metal cover 1 can also not be completely covered by the metal cortical structure 16, and a part of the non-metal inner layer structure 17 can be exposed from the metal cortical structure 16, for example.

[0104] As Figures 1 to 5As shown, the antenna module 2 is fixed to one side of the metal cover 1 where the cover body short slot hole 11 and the cover body long slot hole 12 are formed. The bottom surface structure 27 is arranged facing the metal cover 1. The antenna long slot hole 271 is arranged approximately facing the cover body long slot hole 12, and the antenna short slot hole 272 is arranged approximately facing the cover body short slot hole 11. And the antenna middle structure 275 is arranged approximately corresponding to the cover body middle structure 15. At least a part of the positive projection of the first excitation segment 222 in the direction of the metal cover 1 overlaps with the cover body short slot hole 11. At least a part of the positive projection of the first excitation segment 222 in the direction of the metal cover 1 overlaps with the antenna short slot hole 272. And at least a part of the positive projection of the second excitation segment 223 in the direction of the metal cover 1 overlaps with the cover body long slot hole 12. At least a part of the positive projection of the second excitation segment 223 in the direction of the metal cover 1 overlaps with the antenna long slot hole 271. That is, in the side view as shown in Figure 4 , the first excitation segment 222 of the antenna structure 22 correspondingly straddles the cover body short slot hole 11, and the second excitation segment 223 correspondingly straddles the cover body long slot hole 12.

[0105] It should be noted that in the Figure 5 of this embodiment, the upper edge 224T of the connection segment 224 does not overlap with the upper edge 12T of the cover body long slot hole 12, the upper edge 11T of the cover body short slot hole 11, the upper edge 271T of the antenna long slot hole 271, and the upper edge 272T of the antenna short slot hole 272, but this is not the limit. In different embodiments, the upper edge 224T of the connection segment 224 may also overlap with the upper edge 12T of the cover body long slot hole 12, the upper edge 11T of the cover body short slot hole 11, the upper edge 271T of the antenna long slot hole 271, and the upper edge 272T of the antenna short slot hole 272.

[0106] As described above, when a signal source is fed into the antenna structure 22 through the feeding part 221, the antenna structure 22 can interact with the cover body short slot hole 11 and the antenna short slot hole 272 to generate a first frequency band. The antenna structure 22 can interact with the cover body long slot hole 12 and the antenna long slot hole 271 to generate a second frequency band. The whole antenna structure 22 can resonate to generate a third frequency band. Among them, the frequency ranges corresponding to the first frequency band, the second frequency band, and the third frequency band are not completely the same as each other. Among them, the frequency ranges corresponding to the first frequency band, the second frequency band, and the third frequency band may be completely different. Or, there is partial overlap between the frequency ranges corresponding to the first frequency band and the second frequency band, and there is partial overlap between the frequency ranges corresponding to the second frequency band and the third frequency band. In the embodiment where the cover body long slot hole 12 and the cover body short slot hole 11 are both rectangular closed through holes, the length 11W of the cover body short slot hole 11 may be between 1 / 2 and 4 times the wavelength of the center frequency of the first frequency band, and the length 12W of the cover body long slot hole 12 may be between 1 / 2 and 4 times the wavelength of the center frequency of the second frequency band.

[0107] The electronic device 100 of the present invention further includes a coaxial cable 3. The coaxial cable 3 includes an inner conductor 31 and an outer conductor 32. The inner conductor 31 and the outer conductor 32 are electrically isolated from each other through an insulating structure. The outer conductor 32 is coupled to the first grounding structure 231, and the inner conductor 31 is coupled to the feeding portion 221 of the antenna structure 22. The outer conductor 32 can be connected to the grounding plate 232 by welding with solder, and the outer conductor 32 is electrically conducted to the first grounding structure 231 through the grounding plate 232. The inner conductor 31 can be connected and fixed to the feeding portion 221 of the antenna structure 22 by welding with solder. However, the outer conductor 32 of the coaxial cable 3 can also be directly connected to the first grounding structure 231 without passing through the grounding plate 232, and the same connection effect can be achieved. It is worth mentioning that the grounding plate 232 can further include a notch 2321. The notch 2321 is disposed corresponding to the position of the feeding portion 221, and the notch 2321 is used to prevent the positive and negative poles of the coaxial cable 3 from being connected to each other. In practical applications, the width of the notch 2321 can be designed according to the position of the feeding portion 221 and the position of the first grounding structure 231, and is not limited herein. In a preferred case, the distance between the feeding portion 221 of the antenna structure 22 and the grounding member for connecting to the coaxial cable 3 is not less than 2 millimeters (mm).

[0108] Specifically, in the specific implementation of the electronic device 100 and the antenna module 2 of the present invention, relevant personnel can change the frequency ranges corresponding to the first frequency band, the second frequency band, and the third frequency band by adjusting the position of the first excitation segment 222 relative to the short slot 11 of the cover, adjusting the position of the second excitation segment 223 relative to the long slot 12 of the cover, adjusting the position of the first excitation segment 222 relative to the antenna short slot 272, adjusting the position of the second excitation segment 223 relative to the antenna long slot 271, changing the shape of the first excitation segment 222, changing the shape of the second excitation segment 223, or changing the overall size or shape of the antenna structure 22.

[0109] Please refer to Figure 6 , which shows the voltage standing wave ratio (VSWR) diagram of the antenna module 2 of the first embodiment of the electronic device 100 of the present invention. From Figure 4It can be seen that after the signal source is fed into the electronic device 100 of the present invention, the voltage standing wave ratio at 2.4 GHz is 1.8592, the voltage standing wave ratio at 2.5 GHz is 1.8921, the voltage standing wave ratio at 5.15 GHz is 1.2116, the voltage standing wave ratio at 5.85 GHz is 1.8933, the voltage standing wave ratio at 6.125 GHz is 1.8054, and the voltage standing wave ratio at 7.125 GHz is 1.3170. Therefore, the electronic device 100 and the antenna module 2 of the present invention can support the broadband operations of the commonly used Wi-Fi 6E, 2.4 GHz, and 5 GHz today.

[0110] Please refer to Figure 7 , which shows the radiation efficiency diagram of the antenna module 2 of the first embodiment of the electronic device 100 of the present invention. It can be seen from this diagram that in the three frequency ranges of 6000 - 7125 MHz, 2310 - 2600 MHz, and 5150 - 5850 MHz, the radiation efficiency of the antenna module 2 of the present invention is more than 20%. Therefore, the antenna module 2 of the present invention already meets the application requirements of the commonly used Wi-Fi 6E, 2.4 GHz, and 5 GHz today. It should be noted that in the Figure 6 and Figure 7 shown examples, the metal cover 1 includes a metal cortical structure 16 and a non-metal inner layer structure 17.

[0111] Please refer to again Figure 3 , to enable the antenna structure 22 of the electronic device 100 to better generate three different frequency bands of 6000 - 7125 MHz, 2310 - 2600 MHz, and 5150 - 5850 MHz in the application where the metal cover 1 includes a metal cortical structure 16 and a non-metal inner layer structure 17, the difference between the first length 15W of the cover body intermediate structure 15 and the second length 275W of the antenna intermediate structure 275 is less than 40%, and the length 271W of the antenna long slot hole 271 is not less than 80% of the length 12W of the cover body long slot hole 12, and the length 272W of the antenna short slot hole 272 is not less than 80% of the length 11W of the cover body short slot hole 11.

[0112] Please refer to again Figure 4, in order to enable the antenna structure 22 of the electronic device 100 to better generate three different frequency bands of 6000 - 7125 MHz, 2310 - 2600 MHz, and 5150 - 5850 MHz, in practical applications, the cover short slot hole 11 is a rectangular closed through-hole, and the shortest distance D1 between the first excitation section 222 and one side of the cover short slot hole 11 is not greater than 10 millimeters (mm). The cover long slot hole 12 is a rectangular closed through-hole, and the shortest distance D2 between the second excitation section 223 and one side of the cover long slot hole 12 is not greater than 10 millimeters (mm).

[0113] Please refer to again Figures 2 to 4 , it should be noted that in the drawings of this embodiment, the length 21W of the substrate 21 is greater than the sum of the first length 15W of the cover intermediate structure 15, the length 11W of the cover short slot hole 11, and the length 12W of the cover long slot hole 12 (i.e., 21W ≥ 15W + 11W + 12W). And when the substrate 21 is fixed to the metal cover 1, the substrate 21 will correspondingly shield the cover long slot hole 12 and the cover short slot hole 11 as an example. However, the present invention does not limit that when the substrate 21 is fixed to one side of the metal cover 1, the substrate 21 must completely shield the cover long slot hole 12 and the cover short slot hole 11. As long as the orthographic projection of the first excitation section 222 in the direction of the metal cover 1 overlaps with the cover short slot hole 11, the orthographic projection of the second excitation section 223 in the direction of the metal cover 1 overlaps with the cover long slot hole 12, the orthographic projection of the first excitation section 222 in the direction of the second side surface 212 of the substrate 21 overlaps with the antenna short slot hole 272, and the orthographic projection of the second excitation section 223 in the direction of the second side surface 212 of the substrate 21 overlaps with the antenna long slot hole 271.

[0114] It should be particularly emphasized that if the electronic device and the antenna module do not include the bottom surface structure 27, when the electronic device and the antenna module are applied to a metal cover mixed with non-metallic materials (such as the aforementioned aluminum skin and plastic bone metal cover), it will be difficult for the electronic device and the antenna module to meet the application requirements of Wi-Fi 6E, 2.4 GHz, and 5 GHz. That is, no matter how the relevant personnel modify the appearance or structure of the antenna module, it is difficult to achieve the frequency range of Wi-Fi 6E, 2.4 GHz, and 5 GHz. On the contrary, the electronic device 100 and the antenna module 2 of the present invention, through the designs of the antenna structure 22, the bottom surface structure 27, and the grounding member 23, etc., can effectively meet the current common application requirements of Wi-Fi 6E, 2.4 GHz, and 5 GHz. Even in the case where the metal cover 1 includes a metal cortical structure 16 and a non-metallic inner layer structure 17, the electronic device 100 and the antenna module 2 of the present invention can still meet the application requirements of Wi-Fi 6E, 2.4 GHz, and 5 GHz by simply adjusting the antenna structure 22 and the bottom surface structure 27.

[0115] More specifically, the dielectric constant of the entire metal cover composed only of metal materials (such as the metal cover with aluminum skin and magnesium frame) is completely different from that of the metal cover composed of a mixture of metal materials and non-metal materials (such as the metal cover with aluminum skin and plastic frame). Moreover, for the metal cover mixed with non-metal materials, the dielectric constant of the entire metal cover will also change according to the thickness of the non-metal material. Therefore, for an antenna module without a bottom structure, when applied to a metal cover composed only of metal materials, if it can achieve the frequency ranges that meet Wi-Fi 6E, 2.4 GHz, and 5 GHz, then when the same antenna module is directly applied to a metal cover mixed with non-metal materials (such as the metal cover with aluminum skin and plastic frame), the antenna module will not be able to generate the same frequency band due to the change in the dielectric constant of the metal cover. That is, the antenna module will have a frequency offset problem, resulting in the antenna module not being able to achieve the frequency ranges that meet Wi-Fi 6E, 2.4 GHz, and 5 GHz.

[0116] Please refer to Figure 8 and Figure 9 , Figure 8 which is a schematic diagram of the bottom structure of the antenna module of the second embodiment of the electronic device of the present invention. Figure 9 which is a partial side view of the second embodiment of the electronic device of the present invention. The biggest difference between this embodiment and the foregoing embodiment is that: the bottom structure 27 further includes two frequency modulation structures, which are a first bottom frequency modulation structure 273 and a second bottom frequency modulation structure 274 respectively. The first bottom frequency modulation structure 273 is formed by extending inward from an inner side edge of the antenna long slot hole 271, and the overall shape of the first bottom frequency modulation structure 273 is a rectangular structure protruding from the antenna long slot hole 271, and the height 273H of the first bottom frequency modulation structure 273 is not greater than the height 271H of the antenna long slot hole 271. The second bottom frequency modulation structure 274 is formed by recessing from an inner side edge of the antenna short slot hole 272 in a direction away from the antenna short slot hole 272, and the overall shape of the second bottom frequency modulation structure 274 is a notch concave into the antenna short slot hole 272.

[0117] As Figure 9 shown, after the antenna module 2 is fixed to the metal cover 1, the orthographic projection of the first bottom frequency modulation structure 273 on the metal cover 1 does not overlap with the cover body long slot hole 12, and the orthographic projection of the second bottom frequency modulation structure 274 does not overlap with the cover body short slot hole 11.

[0118] As described above, relevant personnel can adjust at least one of the shape of the first bottom frequency modulation structure 273, the length 273W of the first bottom frequency modulation structure 273, the position of the first bottom frequency modulation structure 273 in the antenna long slot hole 271, and the height 273H of the first bottom frequency modulation structure 273, so as to adjust the low-frequency band (2310 - 2600 MHz) generated by the antenna module 2 and the metal cover 1. Similarly, relevant personnel can adjust at least one of the shape of the second bottom frequency modulation structure 274, the length 274W of the second bottom frequency modulation structure 274, the position of the second bottom frequency modulation structure 274 in the antenna long slot hole 271, and the height 274H of the second bottom frequency modulation structure 274, so as to adjust the 5G frequency band (5150 - 5850 MHz) generated by the antenna module 2 and the metal cover 1. In other words, relevant technical personnel can adjust the first bottom frequency modulation structure 273 and the second bottom frequency modulation structure 274 to correspondingly adjust the frequency ranges of the antenna module 2 at 2.4 GHz and 5 GHz.

[0119] Please refer to Figure 10 , which shows a partial side view of the third embodiment of the electronic device of the present invention. The difference between this embodiment and the first embodiment is that: the antenna structure 22 may further include two frequency modulation bands, which are respectively defined as a first frequency modulation band 225 and a second frequency modulation band 226. The first frequency modulation band 225 connects the connection segment 224 and the first excitation segment 222, and at least a part of the positive projection of the first frequency modulation band 225 in the direction of the metal cover 1 overlaps with the cover body short slot hole 11, and relevant personnel can adjust the frequency range of the first frequency band generated by the antenna module 2 when the signal source is fed into the antenna module 2 by changing the shape, size, and position of the first frequency modulation band 225 relative to the cover body short slot hole 11. That is, the first frequency modulation band 225 is mainly used to adjust the frequency range of the antenna module 2 in Wi-Fi 6E.

[0120] The second frequency modulation band 226 connects the connection segment 224 and the second excitation segment 223, and at least a part of the positive projection of the second frequency modulation band 226 in the direction of the metal cover 1 overlaps with the cover body long slot hole 12, and relevant personnel can adjust the frequency range of the second frequency band generated by the antenna module 2 when the signal source is fed into the antenna module 2 by changing the shape, size, and position of the second frequency modulation band 226 relative to the cover body long slot hole 12. That is, the second frequency modulation band 226 is mainly used to adjust the frequency range of the antenna module 2 in the 2.4G frequency band. Regarding the shapes of the first frequency modulation band 225 and the second frequency modulation band 226 in the drawings of this embodiment, they can be designed according to requirements and are not limited herein.

[0121] Please refer to Figure 11 , which shows a side view of the fourth embodiment of the electronic device of the present invention. The difference between this embodiment and the first embodiment is that: the connection segment 224 of the antenna structure 22 faces the metal cover 1 (such asFigure 2 The positive projection in the direction (as shown) may not overlap with the cover body long slot hole 12, the cover body short slot hole 11, the antenna long slot hole 271, and the antenna short slot hole 272 at all, and the antenna structure 22 further includes a first frequency modulation band 225. For the description of the first frequency modulation band 225, please refer to the third embodiment and will not be elaborated here. Regarding the appearance and dimensions of the first frequency modulation band 225, they can be changed according to the frequency bands generated by the actual antenna module 2 and the metal cover 1, and are not limited to those shown in this embodiment or the third embodiment.

[0122] Please refer to Figure 12 , which shows a side view of the fourth embodiment of the electronic device of the present invention. The biggest difference between this embodiment and the foregoing embodiments is that the antenna structure 22 may further include two frequency modulation members, which are respectively defined as a first frequency modulation member 24 and a second frequency modulation member 25. The first frequency modulation member 24 is connected to the first grounding structure 231, and the first frequency modulation member 24 is coupled to the grounding plate 232. The second frequency modulation member 25 is connected to the second grounding structure 233, and the second frequency modulation member 25 is coupled to the grounding plate 232.

[0123] At least a part of the positive projection of the first frequency modulation member 24 on the metal cover 1 overlaps with the cover body short slot hole 11 and the antenna short slot hole 272, and at least a part of the positive projection of the second frequency modulation member 25 on the metal cover 1 overlaps with the cover body long slot hole 12 and the cover body long slot hole 12. In practical applications, the first frequency modulation member 24 and the first grounding structure 231 may be integrally formed, and the second frequency modulation member 25 and the second grounding structure 233 may be integrally formed. In different embodiments, the first grounding structure 231, the grounding plate 232, the second grounding structure 233, the first frequency modulation member 24, and the second frequency modulation member 25 may be integrally formed. In practical applications, relevant personnel can change the frequency range corresponding to the first frequency band generated by the mutual cooperation of the antenna structure 22 with the cover body short slot hole 11 and the antenna short slot hole 272 when the signal source feeds into the antenna structure 22 by changing the appearance, dimensions, and the position relative to the cover body short slot hole 11 and the antenna short slot hole 272 of the first frequency modulation member 24, and relevant personnel can change the frequency range corresponding to the second frequency band generated by the mutual cooperation of the antenna structure 22 with the cover body long slot hole 12 and the antenna long slot hole 271 when the signal source feeds into the antenna structure 22 by changing the appearance, dimensions, and the position relative to the cover body long slot hole 12 and the antenna long slot hole 271 of the second frequency modulation member 25.

[0124] Please refer to Figure 13, which shows a side view of the sixth embodiment of the electronic device of the present invention. The biggest difference between this embodiment and the foregoing embodiments is that the feeding part 221 can be located at one end of the second excitation segment 223 opposite to the end connected to the connection segment 224, and the feeding part 221 is correspondingly adjacent to the cover body long slot hole 12. Another difference between this embodiment and the foregoing embodiments is that the feeding part 221 is arranged on the first excitation segment 222.

[0125] In practical applications, if the feeding part 221 is arranged on the first excitation segment 222, it will help the performance of the antenna structure 22 in the second frequency band (for example, it can improve the efficiency of the antenna structure 22 in the second frequency band). On the contrary, if the feeding part 221 is arranged on the second excitation segment 223, it will help the performance of the antenna structure 22 in the first frequency band. More specifically, arranging the feeding part 221 on the first excitation segment 222 can improve the performance of the antenna module 2 in the 2.4G frequency band, and arranging the feeding part 221 on the second excitation segment 223 can improve the performance of the antenna module 2 in the Wi-Fi 6E frequency band.

[0126] Another difference between this embodiment and the foregoing embodiments is that the first tuning frequency band 225 is located at the connection position of the first excitation segment 222 and the connection segment 224. The second tuning frequency band 226 is connected to the second excitation segment 223, and the second tuning frequency band 226 is located at the connection position of the second excitation segment 223 and the connection segment 224. More specifically, the first tuning frequency band 225 can be a rectangular structure, and the short side of the first tuning frequency band 225 is connected to the connection segment 224, and the long side of the first tuning frequency band 225 is connected to the first excitation segment 222; the second tuning frequency band 226 can be a rectangular structure, and the short side of the second tuning frequency band 226 is connected to the connection segment 224.

[0127] As described above, in specific implementations, relevant personnel can slightly adjust the frequency ranges of the first frequency band, the second frequency band, and the third frequency band generated by the antenna module 2 by changing the shapes, sizes, installation positions, etc. of the first tuning frequency band 225 and the second tuning frequency band 226. That is to say, the shapes, sizes, and installation positions of the first tuning frequency band 225 and the second tuning frequency band 226 shown in the figures of this embodiment are only one implementation mode, and the actual application is not limited thereto.

[0128] Please also refer to Figure 14 and Figure 15 , Figure 14 , which is a partial schematic diagram of the seventh embodiment of the electronic device of the present invention, Figure 15A partial exploded view of the seventh embodiment of the electronic device of the present invention. The biggest difference between this embodiment and the first embodiment is that: the antenna module 2 may further include an auxiliary frequency modulation member 26. The auxiliary frequency modulation member 26 is disposed on the side surface of the substrate 21, and the antenna structure 22 is located between the auxiliary frequency modulation member 26 and the substrate 21. The auxiliary frequency modulation member 26 is a dielectric material. For example, the auxiliary frequency modulation member 26 may be a member composed of polymers, ceramics, or other composite materials, etc. Wherein, when the auxiliary frequency modulation member 26 is fixed to the substrate 21, the auxiliary frequency modulation member 26 correspondingly shields at least a part of the first excitation segment 222, at least a part of the second excitation segment 223, and at least a part of the connection segment 224.

[0129] In practical applications, relevant personnel can correspondingly adjust the frequency ranges corresponding to the first frequency band, the second frequency band, and the third frequency band generated by the antenna module 2 after the signal source is fed into the antenna module 2 by selecting auxiliary frequency modulation members 26 with different dielectric constants. Additionally, in practical applications, the substrate 21 can be fixed to the metal cover 1 by screws, and the auxiliary frequency modulation member 26 may include an avoidance hole to avoid the screws so that the screws do not need to be locked to the auxiliary frequency modulation member 26. It should be noted that the auxiliary frequency modulation member 26 described in this embodiment can also be combined with any one of the second to sixth embodiments described above to form a new embodiment.

[0130] Please refer to Figure 1 、 Figure 2 and Figure 16 , Figure 16 which is a schematic diagram of the eighth embodiment of the electronic device of the present invention. As shown in Figure 1 and Figure 2 In the foregoing embodiments, the cover short slot hole 11 and the cover long slot hole 12 are formed on the wide side wall 14 of the metal cover 1, and the substrate 21 is disposed on the wide side wall 14 of the metal cover 1. In this embodiment, the cover short slot hole 11 and the cover long slot hole 12 are formed on the narrow side wall 13 of the metal cover 1, and the substrate 21 is disposed on the narrow side wall 13, and a part of the grounding piece 232 of the grounding member 23 can be disposed on the wide side wall 14 of the metal cover 1. In other words, as long as the cover short slot hole 11 and the cover long slot hole 12 can cooperate with the antenna module 2 to generate Wi-Fi 6E, 2.4 GHz, and 5 GHz frequency bands, the cover short slot hole 11 and the cover long slot hole 12 can be disposed at any position on the metal cover 1.

[0131] In summary, the electronic device and antenna module of the present invention can generate three different frequency bands after the signal source is fed. Thus, it can be applied to electronic devices with a small volume or limited installation space. Moreover, through the design of the bottom surface structure, the electronic device and antenna module of the present invention can still generate Wi-Fi 6E, 2.4 GHz, and 5 GHz frequency bands even when the metal cover includes a metal cortical structure and a non-metal inner layer structure.

[0132] The above are only the preferred and feasible embodiments of the present invention, and do not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the content of the specification and drawings of the present invention are included in the protection scope of the present invention.
