Detailed Implementation

[0023] The dual-band high-gain antenna proposed in this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and use non-precise scales, used only to facilitate and clarify the illustration of the embodiments of this invention. Furthermore, the structures shown in the drawings are often part of the actual structure. In particular, different figures may emphasize different aspects and sometimes use different scales.

[0024] With the continuous development of 5G base station construction, the frequency bands supported by communication terminals are also constantly expanding. Nowadays, network communication devices are commonly used terminal products. With the continuous development of technology, devices such as routers inevitably use 5G communication technology. This requires increasing the number of antennas in routers. However, router space is limited, and antenna bandwidth is also limited by space, resulting in limited frequency band coverage and making it difficult to achieve wide bandwidth radiation, thus affecting antenna radiation performance. Dual-band WiFi antennas refer to antennas that can operate simultaneously on both 2.4GHz and 5.8GHz frequency bands. This antenna design allows it to provide stable signal transmission at different frequencies, adapting to different network environments and needs. Dual-band antennas offer the advantages of stronger and more stable models. However, while current dual-band antennas can operate on both 2.4GHz and 5.8GHz frequency bands, they are less able to avoid interference and attenuation problems. Therefore, they need to provide stronger signal coverage and more stable connections, as well as higher transmission rates.

[0025] Therefore, the present invention provides a dual-band high-gain antenna, which includes a substrate, a first radiating component 10, a second radiating component 20, a power divider assembly 30, and a grounding assembly 40; the first radiating component 10 and the second radiating component 20 are respectively disposed on two sides of the substrate, the power divider assembly 30 is electrically connected to the first radiating component 10, and the grounding assembly 40 is electrically connected to the first radiating component 10 and the second radiating component 20; the first radiating component 10 includes a plurality of first dipole antennas 11, and every two groups of first dipole antennas 11 are connected in series to form a first dipole antenna pair 12, and the power divider assembly 30 connects a plurality of first dipole antenna pairs 12 in parallel.

[0026] This configuration simplifies the overall circuit structure of the dual-band high-gain antenna of the present invention and effectively improves its overall radiation performance, mitigating interference and attenuation issues, thereby enhancing radiation gain and efficiency. Specifically, by placing the first radiating component 10 and the second radiating component 20 on opposite sides of the substrate, space is fully utilized, effectively reducing the overall size of the antenna and making it more suitable for space-constrained networking devices such as routers. The first radiating component 10 uses several sets of first dipole antennas 11 connected in series to form a first dipole antenna pair 12, which is then connected in parallel by a power divider circuit component 30. This optimizes the antenna's radiation structure, enabling more effective concentration and radiation of electromagnetic waves, thus improving its radiation performance.

[0027] Furthermore, the first dipole antenna 11 includes a first antenna stub 110, a second antenna stub, and a first grounding element 41. Both the first antenna stub 110 and the second antenna stub are U-shaped, with the notches of the first antenna stub 110 and the second antenna stub facing away from each other. This configuration, with its U-shaped antenna stubs, helps enhance the antenna's radiation efficiency and directivity, giving it stronger radiation capability in a specific direction. The facing away arrangement of the notches of the first antenna stub 110 and the second antenna stub helps reduce mutual interference between antennas and improves the overall performance of the antenna.

[0028] Preferably, the first grounding unit 41 is located at the center of the first dipole antenna 11, and the first grounding unit 41 is electrically connected to the first antenna stub 110 and / or the second antenna stub. This helps to stabilize the electrical performance of the antenna and ensures that the antenna has stable radiation characteristics during operation.

[0029] Furthermore, the second radiating component 20 includes several sets of second dipole antennas 21, which are connected in series. This arrangement, where the second radiating component 20 uses several sets of second dipole antennas 21 connected in series, corresponds to the structure of the first radiating component 10, together forming the radiation system of a dual-band high-gain antenna. This series structure helps to enhance the overall radiation intensity of the antenna, improving signal coverage and stability. Figure 1 and 2 As shown, the number of second dipole antennas 21 in the second radiating component 20 of the present invention can be two or three. Of course, the number of second dipole antennas 21 can also be other values, which are not limited here.

[0030] Specifically, the second dipole antenna 21 includes a third antenna stub 210, a fourth antenna stub 211, and a second grounding element 42. Both the third antenna stub 210 and the fourth antenna stub 211 are U-shaped, with the notches of the third antenna stub 210 and the fourth antenna stub 211 facing away from each other. This arrangement ensures that the U-shaped antenna stubs are equally important for the second dipole antenna 21, improving its radiation efficiency and directivity, resulting in superior radiation performance in specific frequency bands and directions. The facing-away notches of the third antenna stub 210 and the fourth antenna stub 211 further reduce mutual interference between antennas and optimize the antenna's radiation characteristics.

[0031] Preferably, the second grounding unit 42 is located at the center of the second dipole antenna 21, and the first grounding unit 41 is electrically connected to the third antenna stub 210 and / or the fourth antenna stub 211. This configuration ensures that the second dipole antenna 21 has stable electrical performance during operation, effectively avoiding fluctuations in radiation characteristics caused by unstable electrical performance, thereby further guaranteeing stable transmission of antenna signals.

[0032] Furthermore, the power divider assembly 30 includes a first power divider line 31 and a second power divider line 32, which are sequentially connected and then connected in parallel to the first dipole antenna pair 12. Preferably, the lengths of both the first power divider line 31 and the second power divider line 32 are configured to be one-quarter wavelengths. This configuration ensures that the signal maintains low loss during transmission and achieves good impedance matching, thereby improving the antenna's radiation efficiency and signal coverage. This length configuration also helps simplify the circuit structure, reduce unnecessary line losses and interference, and make the overall antenna performance more stable and reliable.

[0033] Furthermore, the power divider assembly 30 also includes a small substrate 33, which is electrically connected to the first power divider line 31 and the second power divider line 32. The introduction of the small substrate 33 in this invention not only provides stable support and electrical connection for the power divider lines but also facilitates the overall layout and installation of the antenna. By rationally designing the size and shape of the small substrate 33 according to user requirements, the space utilization of the antenna can be further optimized, making it more adaptable to the application needs of various network communication devices. In addition, the tight connection between the small substrate 33 and the power divider lines ensures the stability and reliability of signal transmission, thereby improving the overall performance of the antenna.

[0034] In summary, this invention provides a dual-band high-gain antenna and a networking electronic device. The dual-band high-gain antenna includes a substrate, a first radiating component 10, a second radiating component 20, a power divider assembly 30, and a grounding assembly 40. The first radiating component 10 and the second radiating component 20 are respectively disposed on opposite sides of the substrate. The power divider assembly 30 is electrically connected to the first radiating component 10, and the grounding assembly 40 is electrically connected to both the first radiating component 10 and the second radiating component 20. The first radiating component 10 includes several sets of first dipole antennas 11, with each pair of first dipole antennas 11 connected in series to form a first dipole antenna pair 12. The power divider assembly 30 connects several first dipole antenna pairs 12 in parallel. This dual-band high-gain antenna not only simplifies the overall antenna circuitry but also effectively improves the overall antenna radiation performance, effectively mitigating interference and attenuation issues, thereby increasing the antenna's radiation gain and radiation efficiency.

[0035] This invention's dual-band high-gain antenna demonstrates significant advantages in practical applications. Due to its unique structural design, the antenna achieves efficient radiation in both the 2.4GHz and 5.8GHz frequency bands, effectively meeting the multi-band operation requirements of modern network communication equipment. Particularly in space-constrained devices such as routers, this antenna achieves miniaturization while maintaining excellent radiation performance through optimized circuit structure and radiating component layout.

[0036] Furthermore, the design and connection of the dipole antenna pair and power divider circuit assembly 30 in this antenna effectively improves the overall radiation gain and efficiency of the antenna. By configuring the length of the power divider circuit to be a quarter wavelength, low-loss signal transmission and good impedance matching are achieved, further enhancing the stability and reliability of the antenna. Simultaneously, the introduction of the small substrate 33 not only provides stable support for the power divider circuit but also facilitates the overall layout and installation of the antenna, improving space utilization. In actual tests, this dual-band high-gain antenna demonstrated strong anti-interference capability and attenuation suppression effect. Even in complex electromagnetic environments, the antenna can maintain stable signal transmission, effectively avoiding signal quality degradation caused by interference and attenuation. This characteristic makes this antenna widely applicable in rapidly developing fields such as 5G base station construction, smart homes, and the Internet of Things.

[0037] In summary, the dual-band high-gain antenna and network communication electronic equipment proposed in this invention successfully address the shortcomings of existing antennas in terms of radiation performance, space utilization, and anti-interference capabilities through innovative structural design and optimized layout. This antenna not only simplifies the circuit structure and improves radiation efficiency but also enhances anti-interference and attenuation suppression capabilities, providing strong technical support for the development of modern network communication equipment.
