The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Reference below Figure 1-Figure 5 Description The WIFI antenna 100 according to the embodiment of the present utility model may be a WIFI 5G antenna, a WIFI 2.4G antenna, or other types of WIFI antennas, which are not specifically limited herein.

[0028] like Figure 1-Figure 5As shown, the WIFI antenna 100 includes: an antenna body 10, the antenna body 10 has a first surface 11 and a second surface 12 relative to each other, the first surface 11 is formed with a first connecting line portion 13, and the second surface 12 is formed with a second connecting line portion 14; a plurality of first radiating arrays 15, the plurality of first radiating arrays 15 are formed on the first surface 11, and the plurality of first radiating arrays 15 are connected in series through the first connecting line portion 13; a plurality of second radiating arrays 16, the plurality of second radiating arrays 16 are formed on the second surface 12, and the plurality of second radiating arrays 16 are connected in series through the second connecting line portion 14, and the plurality of first radiating arrays 15 and the plurality of second radiating arrays 16 correspond to each other one by one.

[0029] The antenna body 10 may be a plate having a first surface 11 and a second surface 12 opposite to each other. Specifically, the thickness of the antenna body 10 may be set to 0.7 mm-0.9 mm, for example, the thickness of the antenna body 10 may be set to 0.8 mm. A first connecting line portion 13 is formed on the first surface 11, and the first connecting line portion 13 may be formed by etching the first surface 11, and there may be at least one first connecting line portion 13, for example, there may be two, three, four, etc. first connecting line portions 13, but the utility model is not limited thereto, and the antenna body 10 may also have other numbers of first connecting line portions 13, as long as there are multiple first connecting line portions 13. A second connecting line portion 14 may be formed on the second surface 12, and the second connecting line portion 14 may be formed by etching the second surface 12, and there may be at least one second connecting line portion 14, for example, there may be two, three, four, etc. second connecting line portions 14, but the utility model is not limited thereto, and the antenna body 10 may also have other numbers of second connecting line portions 14, as long as there are multiple second connecting line portions 14.

[0030] The antenna body 10 may have a plurality of first radiation arrays 15, for example, the antenna body 10 may have two, three, or four first radiation arrays 15, but the present invention is not limited thereto, and the antenna body 10 may also have other numbers of first radiation arrays 15, as long as there are multiple first radiation arrays 15. It can be explained that the number of first radiation arrays 15 can be set and adjusted according to the gain requirements. A plurality of first radiation arrays 15 may be formed on the first surface 11, for example, a plurality of first radiation arrays 15 may be etched on the first surface 11, and the plurality of first radiation arrays 15 are connected in series through the first connecting line portion 13, so that the plurality of first radiation arrays 15 can perform energy extrusion at the same time, thereby improving the gain effect of the WIFI antenna 100.

[0031] The antenna body 10 may have a plurality of second radiation arrays 16, for example, the antenna body 10 may have two, three, or four second radiation arrays 16, but the present invention is not limited thereto, and the antenna body 10 may also have other numbers of second radiation arrays 16, as long as there are multiple second radiation arrays 16. It can be explained that the number of second radiation arrays 16 can be set and adjusted according to the gain requirements. A plurality of second radiation arrays 16 are formed on the second surface 12, for example, a plurality of second radiation arrays 16 can be etched on the second surface 12, and the plurality of second radiation arrays 16 are connected in series through the second connecting line portion 14, so that the plurality of second radiation arrays 16 can perform energy extrusion at the same time, thereby improving the gain effect of the WIFI antenna 100.

[0032] A plurality of first radiation arrays 15 and a plurality of second radiation arrays 16 are matched one by one, a first radiation array 15 and a second radiation array 16 are overlapped and matched along the thickness direction of the antenna body 10, a first radiation array 15 and a second radiation array 16 form a group of radiation arrays, a first radiation array 15 and a second radiation array 16 perform energy compression, and squeeze all energy between the first surface 11 and the second surface 12 of the antenna body 10 as much as possible, so as to achieve a higher gain effect, thereby meeting the high gain project requirements of the WIFI antenna 100, and can also reduce the manufacturing cost of the WIFI antenna 100. For example: the gain of superimposed three groups of radiation arrays can basically stably reach 6dbi, and the gain of superimposed four groups of radiation arrays can basically stably reach 8dbi.

[0033] It can be explained that the number of superimposed arrays can be reasonably selected according to the gain requirement, thereby improving the gain effect of the WIFI antenna 100.

[0034] According to the WIFI antenna 100 of the embodiment of the utility model, a plurality of first radiating arrays 15 connected in series through a first connecting line portion 13 are arranged on the first surface 11 of the antenna body 10, and a plurality of second radiating arrays 16 connected in series through a second connecting line portion 14 are arranged on the second surface 12 of the antenna body 10, and the plurality of first radiating arrays 15 and the plurality of second radiating arrays 16 are matched one by one to form a double-sided reverse superposition array unit, which can improve the upper limit of the gain of the WIFI antenna 100, thereby improving the gain effect of the WIFI antenna 100, thereby meeting the high gain requirement of the WIFI antenna 100, and can also reduce the manufacturing cost of the WIFI antenna 100.

[0035] According to some embodiments of the present invention, Figure 1As shown, the current flow direction of the first connecting wire portion 13 and the current flow direction of the second connecting wire portion 14 can be opposite. After the current is passed through the first connecting wire portion 13 and the second connecting wire portion 14, such a configuration can enable the multiple first radiation arrays 15 on the first surface 11 and the multiple second radiation arrays 16 on the second surface 12 to perform energy compression, thereby squeezing all the energy between the first surface 11 and the second surface 12 of the antenna body 10 as much as possible, achieving a higher gain effect, thereby meeting the high gain project requirements of the WIFI antenna 100, and can also reduce the manufacturing cost of the WIFI antenna 100.

[0036] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, a plurality of first radiation arrays 15 are arranged in sequence along the first direction, and a plurality of second radiation arrays 16 are arranged in sequence along the first direction. In addition, along the second direction, the first radiation arrays 15 and the corresponding second radiation arrays 16 are arranged correspondingly, and the first direction is perpendicular to the second direction.

[0037] The first direction can be Figure 1-Figure 3 The X direction in the second direction can be Figure 3 The Y direction of the antenna is perpendicular to the first direction. A plurality of first radiation arrays 15 can be arranged in sequence along the first direction, and a plurality of second radiation arrays 16 can be arranged in sequence along the first direction, and along the second direction, the first radiation arrays 15 and the corresponding second radiation arrays 16 are correspondingly arranged, so that the plurality of first radiation arrays 15 and the plurality of second radiation arrays 16 are matched one by one, so that the first radiation arrays 15 and the corresponding second radiation arrays 16 perform energy compression, and squeeze all the energy between the first surface 11 and the second surface 12 of the antenna body 10 as much as possible, so as to achieve a higher gain effect, thereby meeting the high gain project requirements of the WIFI antenna 100, and can also reduce the manufacturing cost of the WIFI antenna 100.

[0038] Specifically, the first radiation array 15 may be U-shaped, and its opening direction is open toward one side along a first direction. The second radiation array 16 may also be U-shaped, and its opening direction is opposite to that of the first radiation array 15.

[0039] It can be explained that the arrangement distance between the plurality of first radiation arrays 15 and the arrangement distance between the plurality of second radiation arrays 16 can be set and adjusted according to actual conditions, and can be combined with the dielectric constant of the substrate, that is, the dielectric constant of the antenna body 10. The dielectric constant of the antenna body 10 can be 0.8C2 / (N·M 2 )-1C2 / (N·M 2 ), find the optimal array spacing, thereby improving the gain effect of the WIFI antenna 100.

[0040] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, along the second direction, the orthographic projection of the first radiating array 15 and the orthographic projection of the corresponding second radiating array 16 may have an overlapping area, so that the first radiating array 15 and the corresponding second radiating array 16 are arranged one-to-one, so that a plurality of first radiating arrays 15 and a plurality of second radiating arrays 16 are matched one-to-one to form a double-sided reverse superposition array unit, which can improve the gain upper limit of the WIFI antenna 100, thereby improving the gain effect of the WIFI antenna 100, thereby meeting the high gain project requirements of the WIFI antenna 100, and can also reduce the manufacturing cost of the WIFI antenna 100.

[0041] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, along the first direction, the first radiation array 15 and the corresponding second radiation array 16 are staggered so that the multiple first radiation arrays 15 on the first surface 11 and the multiple second radiation arrays 16 on the second surface 12 can all perform energy compression, thereby squeezing all energy into the thickness surface of the antenna body 10 as much as possible to achieve a higher gain effect, thereby meeting the high gain project requirements of the WIFI antenna 100 and reducing the manufacturing cost of the WIFI antenna 100.

[0042] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, along the first direction, the offset dimension D of the first radiation array 15 and the corresponding second radiation array 16 satisfies the relationship: 0.3mm≤D≤0.5mm, that is, D can be any value between 0.3mm-0.5mm, for example: D can be 0.3mm, 0.31mm, 0.4mm, 0.42mm, 0.5mm and other values, but the utility model is not limited thereto, and the offset dimension D of the first radiation array 15 and the corresponding second radiation array 16 can also be other values, as long as the offset dimension D is any value between 0.3mm-0.5mm. Thus, the first radiation array 15 and the corresponding second radiation array 16 are arranged in an offset manner, which can facilitate the energy compression of the multiple first radiation arrays 15 on the first surface 11 and the multiple second radiation arrays 16 on the second surface 12, so as to squeeze all the energy into the thickness surface of the antenna body 10 as much as possible, to achieve a higher gain effect, thereby meeting the high gain project requirements of the WIFI antenna 100, and can also reduce the manufacturing cost of the WIFI antenna 100.

[0043] According to some embodiments of the present invention, Figure 1 and Figure 2As shown, a first connecting line portion 13 is connected between two adjacent first radiating arrays 15, and a second connecting line portion 14 is connected between two adjacent second radiating arrays 16, so as to achieve an effect that multiple first radiating arrays 15 are connected in series through the first connecting line portion 13 and multiple second radiating arrays 16 are connected in series through the second connecting line portion 14, so that the multiple first radiating arrays 15 and the multiple second radiating arrays 16 are all subjected to energy compression, and all energy is squeezed as much as possible on the thickness surface of the antenna body 10, so as to achieve a higher gain effect, thereby meeting the high gain project requirements of the WIFI antenna 100, and can also reduce the manufacturing cost of the WIFI antenna 100.

[0044] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the first connecting line portion 13 connected between the two first radiating arrays 15 at the end may have a feeding area 17, and the second connecting line portion 14 connected between the two second radiating arrays 16 at the end may have a feeding area 18. The first connecting line portion 13 provided with the feeding area 17 and the second connecting line portion 14 provided with the feeding area 18 may be arranged correspondingly along the second direction. Along the first direction, the feeding area 17 may be arranged close to the feeding area 18, and the feeding area 18 and the feeding area 17 are connected. For example, the feeding area 18 and the feeding area 17 are connected by a wire, so that the current of the WIFI antenna 100 can flow back simultaneously on the first surface 11 and the second surface 12 of the antenna body 10, thereby causing the multiple first radiating arrays 15 and the multiple second radiating arrays 16 to perform energy compression, thereby squeezing all energy on the thickness surface of the antenna body 10 as much as possible, thereby achieving a higher gain effect.

[0045] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the WIFI antenna 100 may further include: a third connecting line portion 19, the antenna body 10 may have a through hole 20, the third connecting line portion 19 is penetrated through the through hole 20, and the third connecting line portion 19 is connected between the feeding area 17 and the feeding area 18. Such a configuration can further enable the current of the WIFI antenna 100 to flow back simultaneously on the first surface 11 and the second surface 12 of the antenna body 10, thereby further enabling the multiple first radiation arrays 15 and the multiple second radiation arrays 16 to perform energy compression, thereby squeezing all energy on the thickness surface of the antenna body 10 as much as possible, achieving a higher gain effect, thereby meeting the high gain project requirements of the WIFI antenna 100, and reducing the manufacturing cost of the WIFI antenna 100.

[0046] According to some embodiments of the present invention, Figure 2 and Figure 5As shown, the second surface 12 may also be formed with a frequency adjustment circuit 21, and the shape of the frequency adjustment circuit 21 may be various, for example, the shape of the frequency adjustment circuit 21 may be a straight line segment, a T-shape, etc., but the utility model is not limited thereto, and the frequency adjustment circuit 21 may also be other shapes, as long as the frequency adjustment circuit 21 can play a regulating role. The frequency adjustment circuit 21 is connected to the second radiating array 16 at the end, for example, the frequency adjustment circuit 21 and the second radiating array 16 at the end may be integrally formed, or the frequency adjustment circuit 21 and the second radiating array 16 at the end may also be connected by a wire, but the utility model is not limited thereto, as long as the frequency adjustment circuit 21 is connected to the second radiating array 16 at the end. Thus, the frequency adjustment circuit 21 is connected to the second radiating array 16 at the end, which can ensure that the frequency of the WIFI antenna 100 can be adjusted.

[0047] According to some embodiments of the utility model, the antenna body 10 can be a PCB board, and the PCB board is a high-frequency board, so that the WIFI antenna 100 can work normally, and the gain effect of the WIFI antenna 100 can be improved, thereby meeting the high-gain project requirements of the WIFI antenna 100, and the manufacturing cost of the WIFI antenna 100 can be reduced.
