Description

Technical Field

[0002] As consumers' requirements for the appearance and texture of electronic products are getting higher and higher, the all-metal design of electronic consumer products such as laptops and mobile phones has become a development trend in the industry. However, the all-metal design of the electronic product housing greatly restricts the antenna placement position and compresses the antenna space. The low-profile space that can be reserved in the all-metal housing is extremely small and cannot accommodate a common PIFA (Planar Inverted-F Antenna), which poses a huge challenge to the efficiency and directivity design of the antenna.

[0003] For all-metal and low-profile all-metal housings, the existing antenna solutions for electronic devices adopt solutions such as T-shaped slot antennas and one-shaped slot antennas, and the slot antennas radiate electromagnetic waves by coupling special metal structures. However, these two slot antennas also have various disadvantages. For example, the T-shaped slot antenna needs to open a window in the metal housing, which affects the appearance of the metal housing and has a high cost; the one-shaped slot antenna needs to leave an antenna clearance inside the metal housing, but its directivity is very obvious and the antenna efficiency is poor.

[0049] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0050] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0051] Combined with Figure 1 and Figure 2 As shown, an embodiment of the present disclosure provides a waveguide cavity antenna that can be disposed in the heat dissipation channel of an electronic device, which includes an antenna bracket 1, an antenna branch 2, and a waveguide structure member 3; a plurality of through cavity channels 11 are provided in the antenna bracket 1 itself; the antenna branch 2 is disposed on an outer wall of the antenna bracket 1; the waveguide structure member 3 is respectively disposed on two opposite outer walls of the antenna bracket body 1; wherein, the waveguide structure member 3 can be electrically connected to an external metal part to form a waveguide structure; the antenna branch 2 is located between the two waveguide structure members 3 and can jointly form an unclosed waveguide cavity with the waveguide structure member 3.

[0052] The waveguide cavity antenna provided in the embodiments of the present disclosure is particularly suitable for electronic products with all-metal casings, and can be specifically but not limited to being applied to laptop computers, tablet computers, mobile phones, smart wearable devices, etc. The use process is specifically explained by taking the application in a laptop computer as an example.

[0053] When the waveguide cavity antenna is installed and used, the shape of the antenna bracket 1 can be conformally adapted to the shape of the heat dissipation channel in the laptop computer, and the installation and fixation of the waveguide cavity antenna can be achieved by specifically fixing the antenna bracket 1 to the heat dissipation channel.

[0054] Furthermore, the waveguide structural members 3 arranged on two opposite outer walls of the antenna bracket body 1 can be overlapped with the upper shell and the lower shell of the full metal shell in the laptop computer through conductive parts, thereby forming a more complete waveguide structure with the upper shell and the lower shell of the full metal shell respectively, thereby significantly improving the radiation efficiency of the waveguide cavity antenna through the coupling effect of the full metal shell; and the antenna branch 2 arranged in the other outer wall of the antenna bracket body 1 can be correspondingly located between the two waveguide structural members 3, so that the antenna branch 2 can form a non-closed waveguide cavity together with the two waveguide structural members 3, so that the cavity antenna can achieve better antenna efficiency and omnidirectionality.

[0055] In addition, a through cavity 11 is correspondingly opened in the antenna bracket 1. After the waveguide cavity antenna is plugged and fixed in the heat dissipation channel in the full metal shell, it will not affect the normal ventilation and heat dissipation function of the heat dissipation channel, and there is no need to make additional windows or slits in the full metal shell, thereby minimizing the impact of the waveguide cavity antenna on the external structure of the full metal shell.

[0056] To sum up, compared with the prior art method of using slot antennas in all-metal shell electronic devices, the waveguide cavity antenna provided by the embodiment of the present disclosure can be cleverly installed in the heat dissipation channel of the all-metal shell of the electronic device, without the need for additional window openings and slits in the all-metal shell, and the waveguide structure 3 can also be coupled with the upper shell and the lower shell of the all-metal shell respectively to form a more complete and larger waveguide structure, thereby significantly improving the radiation efficiency of the waveguide cavity antenna, and has the beneficial effects of high signal radiation efficiency, clever and compact installation method, and no influence on the appearance of the all-metal shell.

[0057] In one embodiment, the waveguide structure 3 includes a first waveguide component 31 and a second waveguide component 32; the first waveguide component 31 is arranged on the top wall of the antenna bracket 1, and the second waveguide component 32 is arranged on the bottom wall of the antenna bracket 1; the antenna branch 2 is arranged on a side wall of the antenna bracket 1 facing the cavity 11.

[0058] Specific, combined Figure 1 and Figure 2For further detailed description, the waveguide structure member 3 is specifically arranged to include a first waveguide member 31 and a second waveguide member 32. Moreover, the first waveguide member 31 is arranged on the top wall of the antenna bracket 1, and the second waveguide member 32 is arranged on the bottom wall of the antenna bracket 1. In this way, sufficient space can be formed between the first waveguide member 31 and the second waveguide member 32 for clamping the antenna stub 2. And the antenna stub 2 is arranged on a side peripheral wall of the antenna bracket 1 facing the cavity 11. In this way, the peripheral wall where the antenna stub 2 is located, the top wall where the first waveguide member 31 is located, and the bottom wall where the second waveguide member 32 is located can form an unclosed semi-frame-shaped waveguide cavity, and by forming a waveguide cavity with a larger area and a more complete shape, the antenna efficiency can be fully ensured.

[0059] The specific setting method of the positions of the above-mentioned first waveguide member 31, second waveguide member 32 and antenna stub 2 has the beneficial effects of simple structure and being able to form a larger and more complete waveguide cavity.

[0060] In an implementable embodiment, a conductive member 33 is further arranged in the first waveguide member 31 and the second waveguide member 32; the first waveguide member 31 can be electrically connected to the upper shell wall of the external metal part through the conductive member 33 to form a first waveguide structure; the second waveguide member 32 can be electrically connected to the lower shell wall of the external metal part through the conductive member 33 to form a second waveguide structure.

[0061] Specifically, in combination with Figure 1 For further detailed description, the conductive member 33 can be specifically but not limited to be arranged as conductive cloth, conductive cotton or copper foil, etc. In this way, the first waveguide member 31 can be stably electrically connected to the upper shell wall of the all-metal shell part to form a first waveguide structure, and the second waveguide member 32 can be stably electrically connected to the lower shell wall of the all-metal shell part and the heat dissipation module in the electronic device to form a second waveguide structure, fully ensuring the coupling effect between the first waveguide member 31 and the second waveguide member 32 and the all-metal shell part, and significantly improving the antenna radiation efficiency.

[0062] The specific setting method of the above-mentioned conductive member 33 has the beneficial effects of simple structure and being able to stably realize the electrical connection with the metal shell part.

[0063] In an implementable embodiment, an installation part 12 communicating with the cavity 11 is opened in the outer wall of the antenna bracket 1 where the waveguide structure member 3 is arranged; avoidance openings corresponding to the installation part 12 are respectively opened in the first waveguide member 31 and the second waveguide member 32.

[0064] Specifically, in combination with Figure 1 and Figure 2For further detailed description, an installation part 12 communicating with the cavity 11 is formed in the outer wall of the antenna bracket 1 where the waveguide structure member 3 is arranged. The installation part 12 can be specifically but not limited to be set as a threaded hole, a pin hole, etc. And avoidance openings corresponding to the installation part 12 are respectively formed in the first waveguide member 31 and the second waveguide member 32. In this way, when the antenna bracket 1 is fixedly installed on the heat dissipation channel in the all-metal shell through the installation part 12, the avoidance openings can be used for screws or pins to pass through, so as to prevent the first waveguide member 31 and the second waveguide member 32 from affecting the normal installation and fixation of the antenna bracket 1.

[0065] The specific setting manner of the installation part 12 and the avoidance openings has a simple structure and can realize the stable installation of the antenna bracket 1 in the heat dissipation channel.

[0066] In an implementable embodiment, the first waveguide member 31 and the second waveguide member 32 are arranged parallel to each other at intervals; along the length direction of the antenna bracket 1, the first waveguide member 31 and the second waveguide member 32 at least partially correspond.

[0067] Specifically, in combination with Figure 1 and Figure 2 For further detailed description, the first waveguide member 31 and the second waveguide member 32 are specifically set to be arranged parallel to each other at intervals along the length direction of the antenna bracket 1, and the first waveguide member 31 and the second waveguide member 32 at least partially correspond. In this way, it can be ensured that the first waveguide member 31 and the second waveguide member 32 can have a sufficiently large corresponding area in the length direction of the antenna bracket 1. And when the lengths of the first waveguide member 31 and the second waveguide member 32 are not equal, the first waveguide member 31 and the second waveguide member 32 can be respectively centered and arranged in the top wall and the bottom wall of the antenna bracket 1.

[0068] In an implementable embodiment, the antenna branch 2 includes a low-frequency branch 21 and a high-frequency branch 22; the low-frequency branch 21 includes a first branch and a second branch connected to each other; the first branch extends along the length direction of the antenna bracket 1, and the second branch extends along the height direction of the antenna bracket 1; the high-frequency branch 22 is coupled to the low-frequency branch 21 and includes a vertical branch perpendicular to the second branch and a parallel branch parallel to the second branch.

[0069] Specifically, in combination with Figure 1 and Figure 2For further detailed description, the antenna stub 2 is specifically configured to include a low-frequency stub 21 and a high-frequency stub 22. And the low-frequency stub 211 includes a first stub and a second stub that are connected to each other and extend along the length direction and height direction of the antenna bracket 1 respectively. In this way, the low-frequency stub 21 can stably generate low-frequency signals and can be coupled with the metal housing through the first waveguide member 31 and the second waveguide member 32, improving the radiation efficiency of the low-frequency signals; the high-frequency stub 22 is coupled to the low-frequency stub 21 and includes a vertical stub perpendicular to the second stub and a parallel stub parallel to the second stub. In this way, the high-frequency stub 22 generates high-frequency signals through coupling with the low-frequency stub 21, and moreover, the area of the high-frequency stub 22 is small, enabling flexible layout and being less affected by the installation environment.

[0070] The above specific setting method of the antenna stub 2 has a simple and ingenious structure, can efficiently generate low-frequency and high-frequency signals through the coupling effect, and can be flexibly arranged in a narrow environment.

[0071] In an implementable embodiment, the waveguide cavity antenna further includes an antenna feed 4, and the antenna feed 4 is electrically connected to the connection point where the low-frequency stub 21 and the high-frequency stub 22 meet.

[0072] Specifically, in combination with Figure 1 For further detailed description, the antenna feed 4 is electrically connected to the connection point where the low-frequency stub 21 and the high-frequency stub 22 meet. In this way, the antenna feed 4 can more stably provide an excitation signal to the antenna stub 2.

[0073] In an implementable embodiment, the length, width, and height dimensions of the antenna bracket 1 do not exceed 70mm×8mm×8mm; neither the antenna stub 2 nor the waveguide structure member 3 extends beyond the outer wall surface of the antenna bracket 1.

[0074] Specifically, in combination with Figure 1 For further detailed description, the length, width, and height dimensions of the antenna bracket 1 are limited to not exceeding 70mm×8mm×8mm, and neither the antenna stub 2 nor the waveguide structure member 3 extends beyond the outer wall surface of the antenna bracket 1. In this way, while ensuring the radiation efficiency of the waveguide cavity antenna, the overall size of the waveguide cavity antenna can be minimized as much as possible to better fit into the heat dissipation channel in the electronic device.

[0075] In addition, the embodiment of the present disclosure also provides an electronic device, which includes a device body 5 and the above-mentioned waveguide cavity antenna; the device body 5 has a metal housing, and a heat dissipation channel 51 is provided in the metal housing; the antenna bracket 1 is arranged in the heat dissipation channel 51, and the cavity 11 is correspondingly communicated with the heat dissipation channel 51; the waveguide structure member 3 is electrically connected to the metal housing to form a waveguide structure.

[0076] Specifically, in combination with Figure 3For further detailed description, the electronic device may be, but is not limited to, a laptop computer, a tablet computer, a mobile phone, a smart wearable device, etc. The electronic device includes a device body 5 and the above waveguide cavity antenna. The device body 5 has a metal shell, and a heat dissipation channel 51 is opened in the metal shell. In this way, the antenna support 1 of the waveguide cavity antenna can be correspondingly inserted into the heat dissipation channel 51, and the cavity 11 of the antenna support 1 is correspondingly communicated with the heat dissipation channel 51. Without affecting the normal ventilation and heat dissipation function of the heat dissipation channel 51, the waveguide structure member 3 is electrically connected to the metal shell to form a waveguide structure.

[0077] The electronic device includes the above waveguide cavity antenna and can achieve all the beneficial effects of the above waveguide cavity antenna, which will not be elaborated additionally here. Moreover, since the heat dissipation channel 51 of the electronic device is directly communicated with the external environment, the influence on the signal power of the above waveguide cavity antenna can be ignored regardless of whether the device body 5 is in an open or closed state.

[0078] In an implementable manner, the antenna support 1 is flush-mounted in the heat dissipation channel 51, and the antenna stub 2 is flush with the outer exhaust port of the heat dissipation channel 51.

[0079] Specifically, in combination with Figure 3 For further detailed description, the antenna support 1 is flush-mounted in the heat dissipation channel 51, and the antenna stub 2 is flush with the outer exhaust port of the heat dissipation channel 51. In this way, the antenna stub 2 can have more antenna clearance during actual use, thus ensuring its own signal radiation efficiency.
