[0029] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0030] Laptop products are becoming more and more beautiful in appearance design, and metal shell materials are increasingly widely used. Faced with increasingly challenging structural designs, the antenna window space is getting smaller and smaller. The biggest difficulty with such appearance design is that the coverage of the antenna pattern will be shielded by the structural metal material, which will affect the transmission and reception of wireless signals, and thus affect the user's experience. The appearance structure of the all-metal structure will cause the attenuation of wireless signals, limited transmission range, etc. In order to solve this problem, a radiation module has been developed to improve antenna performance, reduce the impact of metal shielding, greatly increase the breadth of the transmission range and reduce the attenuation of wireless signals by metal shells.

[0031] Combination Figure 1 and Figure 2 As shown, the antenna device provided in the embodiment of the present disclosure includes an antenna and a radiation module; the antenna includes a ground portion 1 and a first radiator 2, the first radiator 2 is electrically connected to the ground portion 1; the radiation module includes a second radiator 3 and a signal source, the second radiator 3 is electrically connected to the signal source, and the signal source is electrically connected to the first radiator 2 and the ground portion 1; wherein, after the radiation module is radiated by the first radiator 2, the second radiator 3 excites a current, and the radiation generated by the current is coupled with the radiation generated by the first radiator 2. In the embodiment of the present disclosure, the second radiator 3 in the radiation module can optimize the efficiency of the first radiator 2 in the antenna. This embodiment can optimize and enhance the first radiator 2 in the antenna.

[0032] The radiator of a traditional antenna is easily shielded in a metal casing, which results in limited signal propagation, dead spots in coverage or directionality problems, and uneven field patterns and dead spots in signal coverage. In the disclosed embodiment, by introducing a radiation module, the field pattern of the antenna device can be adjusted within a limited window space to make it more uniform, thereby reducing or eliminating dead spots in signal coverage.

[0033] In this embodiment, after the radiation module is radiated by the first radiator 2, the second radiator 3 excites a current, and the radiation generated by the current is coupled with the radiation generated by the first radiator 2, so that the propagation path of the electromagnetic wave can be redistributed. This redistribution can effectively offset the metal shielding effect, so that the radiator of the antenna device can still maintain efficient and stable radiation performance in a complex environment, effectively guide and distribute electromagnetic waves, and optimize the radiation efficiency of the antenna device.

[0034] Specifically, the first radiator 2 of the traditional antenna in the full metal shell may cause signal attenuation or complete shielding in certain directions due to the shielding effect. The radiation module is independent of the traditional antenna and works in conjunction with the traditional antenna. The radiation module serves as an auxiliary device to optimize and enhance the performance of the antenna device. The two work together to improve the radiation performance of the antenna device. On the basis of the first radiator 2 of the traditional antenna, the radiation module can provide additional radiation paths through the geometry and position of the second radiator 3 in the radiation module, reduce signal attenuation and reflection loss, correct these attenuation directions, and enable the signal to evenly cover the entire target area.

[0035] The radiation module can be directly integrated into the carrier or shell structure of the antenna, without significantly modifying the original antenna design, and has good compatibility and feasibility. Through actual testing, the antenna equipped with the radiation module is superior to the design using only traditional antennas in terms of gain, bandwidth, radiation efficiency, etc., proving its effectiveness. This optimization not only improves the overall performance of the antenna, but also significantly improves the user's reception experience at different locations.

[0036] In some specific implementations, the plane where the first radiator 2 is located is parallel to the plane where the second radiator 3 is located, so that the propagation path of the electromagnetic wave can be redistributed, so that the radiator of the antenna device can still maintain efficient and stable radiation performance in a complex environment, effectively guide and distribute electromagnetic waves, and optimize the radiation efficiency of the antenna device.

[0037] The plane where the first radiator 2 is located is parallel to the plane where the second radiator 3 is located to form a folding design. The main feature of the folding design is that it can maximize the field coverage of the antenna device in a limited space. Its structural design adopts a geometric shape and size optimized according to the resonant wavelength, so that the antenna device can achieve the best electromagnetic wave distribution in a small space. Specifically: the folding design enables the antenna device to achieve a complex electromagnetic wave propagation path in a relatively small physical space. Through multiple foldings, the effective length of the antenna device is increased, while the actual occupied physical space is greatly reduced. The folding design enables the antenna device to better cover the space in both vertical and horizontal dimensions and reduce the metal shielding effect. The folding structure enables the antenna device to maximize the radiation area of ​​electromagnetic waves in a limited space. This design is particularly suitable for space-constrained devices such as laptops, mobile phones, etc.

[0038] According to the resonant wavelengths of different frequency bands (such as 2.4GHz, 5GHz, and 6GHz), the lengths of the folded parts are designed to be 15.6mm, 7.5mm, and 6.25mm, respectively. By using the folded design, specific geometric dimensions, and waveguide slots 24, the propagation path of the electromagnetic wave is redistributed and the reflection of the frequency band is eliminated; this redistribution can effectively offset the metal shielding effect, so that the signals of these frequency bands in certain directions and spatial positions are superimposed and strengthened, so that the radiator of the antenna device can still maintain efficient and stable radiation performance in a complex environment, effectively guide and distribute electromagnetic waves, and optimize the radiation efficiency of the antenna device. By introducing a folded design, the radiation module redistributes the electromagnetic waves in the metal shell, making the pattern of the antenna device more uniform in these environments, thereby improving the overall performance. The size of each part is optimized to ensure the best match and minimum reflection loss.

[0039] The folded design not only optimizes the matching of the size and wavelength of the antenna device, but also enables the antenna device to maintain a high radiation efficiency in a complex metal environment. Through this design, the directivity problems and multipath effects of the antenna device can be significantly reduced, and the stability of the signal can be improved. The folded design can enhance the radiation field coverage of the antenna device while reducing the impact of metal shielding. Through the folded design, the antenna device can achieve better directivity control and wider signal coverage. Through precise geometric design, the antenna device can concentrate electromagnetic waves in the target direction, reduce unnecessary scattering and reflection, and reduce dead angles and directional deviations common in traditional designs.

[0040] In addition, the foldable design has mechanical stability and can resist external physical shocks and vibrations, ensuring the reliability of the equipment in various environments; it can be easily integrated with the device casing or internal structure without the need for additional installation space or complex support structures.

[0041] In some specific implementations, the second radiator 3 is formed with a waveguide channel.

[0042] In some specific embodiments, the waveguide channel includes a waveguide groove 24. The shape of the waveguide groove 24 can be any of a straight line, an I-shaped, a T-shaped, an F-shaped, and a C-shaped.

[0043] The shape design method of the second radiator 3 is as follows:

[0044] The length and width are designed according to the resonant wavelength. The resonant wavelengths of the antennas operating at 2.4 GHz and 5 GHz are 125 mm and 60 mm respectively, so the physical dimensions are adjusted to these wavelengths, with lengths of 15.6 mm (2.4 GHz), 7.5 mm (5 GHz) and 6.25 mm (6 GHz).

[0045] λ=c / f,c=3*10 8 m / s;

[0046]

[0047] A waveguide groove 24 is provided to guide and distribute electromagnetic waves. The design of the waveguide groove 24 refers to the waveguide theory to ensure that the signal can be transmitted smoothly without being affected by metal shielding.

[0048] Combining the above waveguide theory with the experimental study of antenna resonance wavelength, we can conclude that Figure 2 Radiator of the shape and size described.

[0049] like Figure 2 As shown, in the second radiator 3 of the radiation module, the length of LI can be 18.6mm, the length of L2 can be 9.5mm, and the lengths of L3, L4, L5, L6, L7, L8, L9, and L10 can all be 1mm. The first radiator 2 and the second radiator 3 of the radiation module can maximize the field coverage of the antenna device in a limited space, so that the antenna device can realize a complex electromagnetic wave propagation path in a relatively small physical space. Through multiple folding, the effective length of the antenna device is increased, while the actual occupied physical space is greatly reduced. The antenna device formed by the second radiator 3 of the radiation module can better cover the space in both vertical and horizontal dimensions, reduce the metal shielding effect, and enable the antenna device to maximize the radiation area of ​​electromagnetic waves in a limited space.

[0050] In some specific embodiments, the second radiator 3 is at least one of a strip conductor, a metal sheet, and a flexible printed circuit FPC formed or installed in a non-conductive area of ​​the PCB.

[0051] In some specific embodiments, the second radiator 3 includes radiation pattern parts for receiving or transmitting external signals, respectively.

[0052] In some specific implementations, the radiation pattern portion includes a first radiation portion 21 , and the first radiation portion 21 is in a straight line shape.

[0053] In some specific implementations, the radiation pattern portion includes a second radiation portion 22 and a third radiation portion 23 , the second radiation portion 22 is in a straight line shape, and the third radiation portion 23 is connected to the second radiation portion 22 .

[0054] In some specific implementations, the radiation pattern portion includes a first radiation portion 21 and a second radiation portion 22 , and a gap is provided between the first radiation portion 21 and the second radiation portion 22 .

[0055] The electronic device provided by the embodiment of the present disclosure includes the antenna device provided by the embodiment of the present disclosure. The electronic device provided by the embodiment of the present disclosure has the same advantages as the antenna device provided by the embodiment of the present disclosure.

[0056] like Figure 3 As shown, in the case of a metal shell structure, the radiation pattern of the antenna device provided by the embodiment of the present disclosure has no dead angles, thereby reducing the possibility that the electronic device product has extremely poor signal reception at a certain angle, thereby affecting the user experience.

[0057] Combination Figure 4 and Figure 5 As shown, the actual test verification:

[0058] Gain test: Under the same conditions, the antenna gain of the present invention is about 20% higher than that of the traditional linear antenna, and the signal coverage range is expanded by 15%.

[0059] Throughput test: In actual usage scenarios (such as office environment and home environment), the present invention shows more stable connection performance and lower drop rate.

[0060] The present invention achieves the expansion of the radiation pattern range of the antenna without increasing the physical size of the antenna by designing a folded radiation module. This method ensures uniform coverage of the signal in all directions by controlling the propagation path of electromagnetic waves without increasing the length of the antenna or adding additional antenna units. Therefore, the present invention is significantly different from the traditional enhancement method in terms of design ideas and implementation methods, so the same design will not appear, and it is more suitable for the needs of modern electronic devices.

[0061] Through actual tests, the antenna equipped with the radiation module is superior to the design using only the traditional antenna in terms of gain, bandwidth, radiation efficiency, etc., proving its effectiveness. This optimization not only improves the overall performance of the antenna, but also significantly improves the user's reception experience at different locations.

[0062] The present invention achieves the expansion of the radiation pattern range of the antenna without increasing the physical size of the antenna by designing a folded radiation module. This method ensures uniform coverage of the signal in all directions by controlling the propagation path of electromagnetic waves without increasing the length of the antenna or adding additional antenna units. Therefore, the present invention is significantly different from the traditional enhancement method in terms of design ideas and implementation methods, so the same design will not appear, and it is more suitable for the needs of modern electronic devices.

[0063] The antenna device and electronic device provided by the embodiments of the present disclosure have the following advantages:

[0064] Balance between volume and performance: Many existing antenna designs often require more equipment space when improving signal coverage. However, the present invention achieves the same or even better radiation performance as traditional solutions without increasing the volume of the equipment through the design of a folded radiation module. This makes the present invention particularly suitable for modern electronic devices with extremely high space requirements.

[0065] Space efficiency: Traditional antenna designs often require a larger window area in the metal casing. However, the present invention, through the design of a folded radiation module, can achieve effective electromagnetic wave distribution in a very small space, reducing the need for casing windows.

[0066] Better anti-interference ability: The traditional antenna in the metal shell has weak anti-interference ability and is easily affected by the external electromagnetic environment. However, the present invention has a stronger anti-interference ability in structural design through the folded radiation module, and can better adapt to the complex electromagnetic environment.

[0067] Optimized radiation design: Traditional solutions often require a larger window area in a metal shell environment to reduce signal shielding. The present invention, through the design of a folded radiation module, greatly optimizes the antenna's field coverage while maintaining the integrity of the metal appearance.

[0068] Signal uniformity: By precisely controlling the position and size of the radiation module, the present invention can achieve more uniform signal coverage in metal structures and reduce the dead spot problem common to traditional antennas in metal shell environments.
