Description

Technical Field

[0001] This utility model relates to the field of communication technology, and in particular to a high-gain antenna and a network communication device using the high-gain antenna. Background Technology

[0002] With the continuous development of 5G base station construction, the frequency bands supported by communication terminals are also constantly expanding. Nowadays, mobile phones are commonly used mobile terminal products. With the continuous development of technology, mobile phones inevitably use 5G communication technology, and indoor communication requires wireless communication through network equipment. If the number of antennas is increased further within the mobile phone terminal, the limited space and bandwidth of the antennas will restrict the frequency bands covered, making it difficult to achieve wide bandwidth radiation. However, improving the transmission through network equipment can achieve the same effective results.

[0003] The basic function of an antenna is to convert electrical signals into electromagnetic waves and radiate them, or to convert received electromagnetic waves into electrical signals. In the field of mobile communications, omnidirectional high-gain antennas have a wide range of applications, such as conventional antennas or Franklin antennas. However, existing conventional antennas have poor omnidirectionality and low gain efficiency.

[0004] In view of this, it is indeed necessary to propose a high-gain antenna and a network communication device that uses the high-gain antenna. Utility Model Content

Detailed Implementation

[0026] The high-gain antenna 100 proposed in this utility model 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, and are only used to facilitate and clarify the explanation of the embodiments of this utility model. 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.

[0027] This invention provides a high-gain antenna 100, which can be used in network devices such as routers or ceiling-mounted AR products. Ceiling-mounted AR is a wireless access point installed on the ceiling, primarily used to provide whole-house WiFi coverage. Compared to traditional methods, ceiling-mounted AR is more discreet and does not disrupt the aesthetics of the space. It is commonly used in homes, businesses, schools, and other settings to ensure stable network connectivity in every corner.

[0028] like Figure 1-6 As shown, the high-gain antenna 100 of this invention includes a substrate 10, and a first radiating array 20 and a second radiating array 30 located on both sides of the substrate 10. The first radiating array 20 includes a plurality of first radiators 3121, and a grounding assembly 40 electrically connected to the first radiators 3121. The grounding assembly 40 includes a feed element 41 and a grounding element 42. The first radiators 3121 and the grounding assembly 40 are both disposed on one side of the substrate 10.

[0029] The second radiation array 30 includes a plurality of second radiators, all of which are disposed on the other side of the substrate 10; a plurality of first radiators 3121 are arranged at intervals on the front side of the substrate 10, and a plurality of second radiators are arranged at intervals on the back side of the substrate 10. The plurality of first radiators 3121 and the plurality of second radiators are alternately connected, and adjacent first radiators 3121 and second radiators are interconnected, that is, adjacent first radiators 3121 and second radiators on opposite sides of the substrate 10 are interconnected.

[0030] Preferably, the substrate 10 is rectangular, and both the first radiator 3121 and the second radiator are configured as patch antennas, preferably PCB radiating antennas. Preferably, the distance between adjacent first radiators 3121 is equal to the length of the second radiator, and the distance between adjacent second radiators is equal to the length of the first radiator 3121; and adjacent first radiators 3121 and second radiators are interconnected.

[0031] Each of the first radiators 3121 and each of the second radiators has a slot 212 / 312 surrounding the radiating antenna at the central position. This widens the radiation bandwidth of a single radiator. That is, both the first radiator 3121 and the second radiator include a first radiating branch 210 / 310 and a second radiating branch 211 / 311, with the first radiating branch 210 / 310 surrounding the second radiating branch 211 / 311, and the first radiating branch 210 / 310 and the second radiating branch 211 / 311 forming the slot 212 / 312.

[0032] Furthermore, each of the first radiators 3121 and each of the second radiators is provided with a first connecting through hole 213 / 313 and a second connecting through hole 214 / 314. The first connecting through hole 213 / 313 is formed on the first radiating branch 210 / 310, and the second connecting through hole 214 / 314 is formed on the second radiating branch 211 / 311. Adjacent first radiators 3121 and second radiators are connected through the first connecting through hole 213 / 313 and the second connecting through hole 214 / 314. Specifically, the first connecting through hole 213 / 313 on the first radiating branch 210 / 310 is connected to the second connecting through hole 214 / 314 on the second radiating branch 211 / 311.

[0033] The grounding assembly 40 includes a power supply body 41 and a grounding body 42. The power supply body 41 has a power supply through-hole 410, and the grounding body 42 has a grounding through-hole 420. The grounding assembly 40 is disposed on the front side of the substrate 10, that is, both the power supply body 41 and the grounding body 42 are disposed on the front side of the substrate 10.

[0034] The power supply through-hole 410 of the power supply body 41 is electrically connected to the first connection through-hole 213 / 313 on the first radiating branch 210 / 310 of the second radiator on the reverse side of the substrate 10; the grounding through-hole 420 of the grounding body 42 is electrically connected to the second connection through-hole 214 / 314 on the second radiating branch 211 / 311 of the second radiator on the reverse side of the substrate 10. Preferably, the power supply through-hole 410 and the first connection through-hole 213 / 313 are electrically connected and fixed by screws. Of course, the power supply through-hole 410 and the first connection through-hole 213 / 313 can also be connected in other ways, as long as they can be electrically connected and fixed, and no further restrictions are imposed.

[0035] Of course, the grounding component 40 can also be disposed on the reverse side of the substrate 10, in which case the grounding component 40 is connected to the first radiator 3121 on the front side of the substrate 10. When the grounding component 40 is electrically connected to the first radiator 3121 or the second radiator on the opposite side, the radiators on the front and back sides of the substrate 10 are respectively cross-connected to each other, that is, after one end of the second radiator is connected to the grounding component 40, the other end of the second radiator is connected to one end of the first radiator 3121 on the opposite side, and so on, forming an integral high-gain antenna 100.

[0036] Furthermore, the high-gain antenna 100 also includes a parasitic coupling unit, which includes a first parasitic stub 60 and a second parasitic stub 61. The first parasitic stub 60 and the second parasitic stub 61 are spaced apart from each other, that is, the first parasitic stub 60 and the second parasitic stub 61 are located on the same plane. The first parasitic stub 60 and the second parasitic stub 61 are both located on the front side of the substrate 10, or both are located on the back side of the substrate 10. This can further widen the overall bandwidth of the antenna. Preferably, the first parasitic stub 60 and the second parasitic stub 61 of this invention are both located on the back side of the substrate 10, that is, on the same plane as the first radiating array 20. Specifically, the first parasitic branch 60 is T-shaped and located at the end of the substrate 10, and the first parasitic branch 60 is electrically connected to the first radiating branch 210 / 310 on the front side of the substrate 10; the second parasitic branch 61 is rectangular and located beside the second radiator and spaced apart from the first parasitic branch 60, that is, a second radiator is provided between the first parasitic branch 60 and the second parasitic branch 61, and the second parasitic branch 61 is coupled to the first radiator 3121 on the opposite side.

[0037] The high-gain antenna 100 of this invention utilizes the cross-connection of a first radiating array 20 and a second radiating array 30 on both sides of a substrate 10. Specifically, the first radiators 3121 of the first radiating array 20 and the second radiators of the second radiating array 30 are cross-connected, and adjacent first radiators 3121 and second radiators are electrically connected via connecting vias. This ensures that the voltage and current of each radiator are identical. Preferably, the PCB radiating antenna of this invention can be a high-performance version with a dielectric constant of approximately 2.65 and a DF value between 0.0005 and 0.0015. Preferably, the length of each radiator, i.e., the first radiator 3121 or the second radiator, is one-quarter of the operating wavelength. It should be noted that the operating wavelength of this invention is in the operating frequency band of 5.15-5.85 GHz.

[0038] In summary, this utility model provides a high-gain antenna 100, which is applied in network communication equipment, particularly routers. The high-gain antenna 100 includes a substrate 10, and a first radiating array 20 and a second radiating array 30 located on both sides of the substrate 10. The first radiating array 20 includes a plurality of first radiators 3121 and a grounding assembly 40 electrically connected to the first radiators 3121. The grounding assembly 40 includes a feed element 41 and a grounding element 42. Both the first radiators 3121 and the grounding assembly 40 are disposed on one side of the substrate 10. The second radiating array 30 includes a plurality of second radiators, all disposed on the other side of the substrate 10. The plurality of first radiators 3121 are spaced apart on the front side of the substrate 10, and the plurality of second radiators are spaced apart on the back side of the substrate 10. The plurality of first radiators 3121 and the plurality of second radiators are alternately arranged, and adjacent first radiators 3121 and second radiators are interconnected. The high-gain antenna 100 of this invention not only simplifies the complexity of traditional antenna wiring design, making matching easier and facilitating mass production, but also effectively improves the overall radiation gain and radiation efficiency of the antenna.
