Description
Technical Field
[0001] This disclosure relates to the field of antenna technology, and in particular to an antenna structure and an electronic product having the antenna structure. Background Technology
[0002] As computers / laptops become more powerful, their power consumption also increases. Traditional antennas require additional materials on the motherboard or battery to suppress the impact of noise on antenna performance, which increases the overall cost of the product. Furthermore, the application of these materials requires additional manpower, thus increasing labor costs and reducing the automation rate of the production line.
[0003] To address the above issues, current solutions include: placing the antenna in an open environment, which can reduce the impact of noise on the antenna; however, modern computer screens typically use narrow bezel designs, limiting space; alternatively, redesigning the antenna, such as using RF switches and multi-antenna systems, which requires both hardware and software support and is too costly; or attaching absorbing materials to the motherboard to shield noise sources, which also increases costs and affects the automation rate of the production line. Summary of the Invention
[0004] To address at least the above-mentioned technical problems in the prior art, this disclosure provides an antenna structure and an electronic product having the antenna structure.
[0005] This disclosure provides an antenna structure, including a radiating pattern and a shielding component made of metal. The shielding component includes a shielding wall, a reference ground sheet, and a conductive component. One side of the bottom end of the shielding wall is connected to the reference ground sheet, and the top end of the shielding wall is connected to the conductive component. The reference ground sheet is used to connect to the grounding electrode of a first housing, and the conductive component is used to connect to the grounding electrode of a second housing. The radiating pattern is connected to the bottom end of the shielding wall and is located on one side of the shielding wall. The vertical projection of the radiating pattern toward the shielding wall is located within the area of the shielding wall. The shielding component isolates the side where the radiating pattern is located into a shielded quiet zone.
[0006] In some embodiments, the two ends of the shielding wall each include a side end plate that can be used to form a resonant unit; the side end plate and the shielding wall are an integral structure, and the two side end plates and the radiation pattern are located on the same side of the shielding wall.
[0007] In some embodiments, the radiation pattern includes a planar portion and a bent portion, the planar portion being connected to the shielding wall, and the bent portion being located on the side of the planar portion away from the shielding wall; the plane containing the bent portion is parallel to or forms an angle with the plane containing the shielding wall, and the plane containing the planar portion is perpendicular to or forms an angle with the plane containing the bent portion.
[0008] In some embodiments, a feed line is further included, the first end of which is fixedly connected to the junction of the radiation pattern and the shielding wall; the feed line extends along the bottom of the shielding wall and exits the shielded quiet zone from the side end of the shielding wall.

[0027] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0028] like Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides an antenna structure, which mainly includes a metal part (including a radiating pattern 10 and a shielding component 20), a feed line 30, and a substrate 40.
[0029] The shielding component 20 includes a shielding wall 21, a reference ground sheet 22, and a conductive component 23. One side of the bottom end of the shielding wall 21 is connected to the reference ground sheet 22, and the top end of the shielding wall 21 is connected to the conductive component 23. The reference ground sheet 22 is used to connect to the grounding electrode of the first housing 50, and the conductive component 23 is used to connect to the grounding electrode of the second housing.
[0030] The radiation pattern 10 is connected to the bottom of the shielding wall 21 and is located on one side of the shielding wall 21. For example, the shielding wall 21 and the radiation pattern 10 are arranged perpendicularly to each other. The vertical projection of the radiation pattern 10 toward the shielding wall 21 is located within the area of the shielding wall 21. The shielding member 20 isolates the side where the radiation pattern 10 is located into a shielded quiet zone.
[0031] The shielded quiet zone can be explained as follows: After the antenna structure is installed, a region is isolated by the shielding component 20. Due to the function of the shielding component 20, the high-frequency noise of the motherboard is effectively shielded in this region, thereby reducing the impact of noise on the antenna components in this region, hence the name shielded quiet zone.
[0032] Compared to existing designs that involve attaching conductive foam to batteries or overly complex antenna designs, the shielding component 20 has a simpler structure and can reduce the amount of auxiliary materials used in the entire machine, reduce the number of workers required to apply auxiliary materials on the production line, and improve the automation rate of the production line.
[0033] Continue to refer to Figure 1 and Figure 2 As shown, for example, the reference ground sheet 22 is a copper foil or aluminum foil, which is welded to the shielding wall 21 or connected with conductive adhesive. The copper foil or aluminum foil has a certain unfolded area and is connected to the grounding electrode of the first housing 50, which can enhance the radiation performance of the antenna.
[0034] For example, the first end of the feed line 30 is fixedly connected to the junction of the radiating pattern 10 and the shielding wall 21; the feed line 30 extends along the bottom of the shielding wall 21 and exits the shielded quiet zone from the side end of the shielding wall 21. For example, the feed line 30 is provided along the junction of the bottom of the shielding wall 21 and the radiating pattern 10, welded to the shielding wall 21 or the radiating pattern 10, and exits from the side. This method can reduce the space occupied by the feed line 30 and maximize the space utilization of the antenna structure.
[0035] For example, the conductive component 23 includes conductive foam, and the end of the shielding wall 21 away from the radiation pattern 10 is connected to the grounding component of the second housing through the conductive foam. The conductive foam has good conductivity, and also has the properties of being lightweight, corrosion-resistant, and oxidation-resistant.
[0036] For example, a platform 25 for supporting the conductive element 23 is provided at the end of the shielding wall 21, and the conductive element 23 is disposed on the platform 25, wherein the width of the platform 25 is greater than the width of the shielding wall 21.
[0037] Continue to refer to Figure 1 and Figure 2As shown, the antenna structure also includes a substrate 40; the radiating pattern 10 is superimposed on the substrate 40. For example, the substrate 40 is a 0.3 to 0.8 mm thick adhesive-backed substrate 40, which is connected to the radiating pattern 10 to further protect the antenna structure and prevent deformation caused by external forces during transportation.
[0038] In some embodiments, the two ends of the shielding wall 21 each include a side end plate 24 that can be used to form a resonant unit; the side end plate 24 and the shielding wall 21 are an integral structure, and the two side end plates 24 and the radiation pattern 10 are located on the same side of the shielding wall 21.
[0039] For example, the length of the two side end plates 24 is less than the length of the shielding wall 21. These two side end plates 24 can form a parasitic frequency band (high frequency band) to participate in the radiation of the antenna signal and enhance the antenna performance.
[0040] In addition, the side end plate 24 can also serve as a snap-fit structure for the antenna structure. That is, a downwardly extending protrusion is provided at the bottom of the side end plate 24. This protrusion is a snap-fit structure, which snaps into the outer shell to achieve a stable connection between the two.
[0041] In some embodiments, the radiation pattern 10 includes a planar portion 11 and a bent portion 12. The planar portion 11 is connected to the shielding wall 21, and the bent portion 12 is disposed on the side of the planar portion 11 away from the shielding wall 21. The surface where the bent portion 12 is located is parallel to the surface where the shielding wall 21 is located or forms an angle with a set angle, and the surface where the planar portion 11 is located and the surface where the bent portion 12 is located form an angle with a set angle.
[0042] For example, the angle between the planar portion 11 and the bent portion 12 is set to 90°. During installation, the radiating pattern 10 is mounted on a mounting structure including a right angle. Using this method, double-sided radiation of the antenna can be achieved, the radiating area can be further increased when the installation area is limited, and the antenna structure can be miniaturized. At the same time, the antenna structure can be positioned by the included angle.
[0043] For example, the bent portion 12 can also serve as a snap-fit structure to snap into the outer casing, achieving a stable connection between the two.
[0044] In this embodiment of the disclosure, the radiation pattern 10 includes metal lines arranged in a serpentine pattern. It employs meandering technology, which increases the current path and reduces the resonant frequency. This allows for a low-frequency design within a smaller size, while the meandering technology also has the ability to suppress noise at specific frequencies.
[0045] In a given space, the serpentine radiation pattern 10 of the antenna can take many forms. Among them, the pattern corresponding to the required performance can be determined by simulation and physical prototyping tests. For example, the required operating frequency band resonance can be obtained by parameter scanning in simulation software. This method can save a lot of manpower and obtain the required radiation pattern 10 more quickly.
[0046] For example, the radiating pattern 10 includes bent and / or straight metal lines, and the pattern of appropriate shape can be selected according to the performance of the radiating pattern 10 or the requirements of installation space.
[0047] like Figure 3 and Figure 4 As shown, this embodiment of the present disclosure provides an electronic product, including a housing and the antenna structure described above; the housing includes a first housing 50 and a second housing (not shown), the first housing 50 is provided with an antenna support 51, the antenna structure is connected to the antenna support 51, and a reference ground sheet 22 is connected to the grounding electrode of the first housing 50, and a conductive element 23 is connected to the grounding element of the second housing.
[0048] In some embodiments, the antenna support 51 includes a slot 52, and the radiating pattern 10 and / or the shielding wall 21 are provided with protruding snap-fit structures. When the antenna structure is connected to the antenna support 51, the snap-fit structures snap into the slot 52. The snap-fit between the antenna structure and the support can achieve a stable connection between the two, and the slot 52 protects the antenna structure from damage by external forces.
[0049] In some embodiments, the antenna support 51 includes a thermoplastic column 53, and the radiation pattern 10 and / or shielding wall 21 are provided with a connection hole 13. When the antenna structure is connected to the antenna support 51, the thermoplastic column 53 is connected to the connection hole 13.
[0050] For example, the location for heat fusion is selected based on the placement of the antenna structure, and the heat fusion process must not damage surrounding components. Using heat fusion allows for a stable connection of the antenna structure, meeting the requirements of drop or vibration tests.
[0051] The present disclosure provides an antenna structure and an electronic product having the antenna structure. The shielding component 20 can form a shielded quiet zone around the radiation pattern 10, thereby shielding high-frequency noise on the motherboard. The antenna structure is simple in structure and can reduce the amount of auxiliary materials used in the whole machine. This can not only reduce the production cost of the whole machine, but also reduce the number of workers who apply auxiliary materials on the production line, reduce labor costs, and improve the automation rate of the production line.
