Detailed Implementation

[0055] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this application more complete and comprehensive, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0056] The terms used in this application to express position and direction are illustrated with the accompanying drawings, but may be changed as needed, and all such changes are included within the scope of protection of this application.

[0057] like Figure 1 , Figure 2 and Figure 3 As shown, this application provides a WiFi 6E antenna, including: a substrate 100 and a radiating part, and may further include an IPEX connector 300 and an RF line 200.

[0058] Specifically, the substrate 100 has a first side and a second side along the X-axis direction, a first end and a second end along the Y-axis direction, and a first surface and a second surface opposite each other along the thickness direction. The first surface is the front surface of the substrate 100, and the second surface is the back surface of the substrate 100. The direction from the first side to the second side of the substrate 100 is the width direction of the substrate 100, the direction from the first end to the second end of the substrate 100 is the length direction of the substrate 100, and the direction from the first surface to the second surface of the substrate 100 is the thickness direction of the substrate 100. The substrate 100 can be a flexible printed circuit board (FPC), and the material can be a known insulating material.

[0059] A grounding portion 60 is provided on the first surface of the antenna 100. The grounding portion 60 is close to the first end of the substrate 100. In a preferred embodiment of this application, the grounding portion 60 is a rectangular structure. One side of the grounding portion 60 coincides with the first end of the substrate 100, and the two sides of the grounding portion 60 perpendicular to this side coincide with the first and second sides of the substrate 100. The fourth side of the grounding portion 60 extends along the Y-axis. A radiating portion is provided at a distance of 0.5-2mm from the grounding portion 60. In a preferred embodiment of this application, the distance between the grounding portion 60 and the radiating portion is 1mm.

[0060] The radiating portion of this application is disposed on the first surface of the substrate 100. The radiating portion includes a first radiating plate 10, a second radiating plate 20 and a third radiating plate 30. The first radiating plate 10, the second radiating plate 20 and the third radiating plate 30 are spaced apart in sequence along the Y-axis direction and disposed between the grounding portion 60 and the second end of the substrate 100.

[0061] Specifically, the first radiating plate 10 is spaced 0.5-2 mm from the grounding portion 60. In a preferred embodiment, the first radiating plate 10 is spaced 1 mm from the grounding portion 60. Both the first radiating plate 10 and the grounding portion 60 are electrically connected to a conductor, but they are mutually insulated. In another preferred embodiment, the conductor is a radio frequency (RF) wire 200, 13 mm in length, with different insulated wire bodies. The first radiating plate 10 is electrically connected to one of these wire bodies, and the grounding portion 60 is electrically connected to the other. The first radiating plate 10 and the second radiating plate 20 are electrically connected via a first connecting portion 40, and the second radiating plate 20 and the third radiating plate 30 are electrically connected via a second connecting portion 50.

[0062] As an example, the grounding portion 60, the first radiating plate 10, the second radiating plate 20, the third radiating plate 30, the first connecting portion 40, and the second connecting portion 50 of this application are all copper layers. They can be formed on the substrate 100 by metal coating, firstly by forming a copper film covering the entire first surface, and then by etching or physical removal to form each functional part. By adopting the above structure and method, the structure of the grounding portion 60, the first radiating plate 10, the second radiating plate 20, the third radiating plate 30, the first connecting portion 40, and the second connecting portion 50 is simplified and easy to process. Therefore, the production cost of this application is low. The copper layer thickness of this application is 0.02-0.03 mm. As a preferred embodiment of this application, the copper layer thickness of this application is 0.0254 mm, that is, 25.4 μm.

[0063] In some embodiments, by employing the grounding portion 60, the first radiating plate 10, the second radiating plate 20, the third radiating plate 30, the first connecting portion 40, and the second connecting portion 50 of the above-described structure, the WiFi 6E antenna not only has better performance but also significantly reduces its size. The length of the substrate 100 in this application, i.e., the distance along the Y-axis, is 40-50 mm, the width, i.e., the distance along the X-axis, is 10-20 mm, and the thickness is 0.1-0.2 mm. As a preferred embodiment of this application, the substrate 100 has a length of 45 mm, a width of 15 mm, and a thickness of 0.14 mm, thereby forming a small-sized, high-performance WiFi 6E antenna.

[0064] In some embodiments, a power feeding pad 70 is provided on the first radiating plate 10, and a grounding pad 80 is provided on the grounding portion 60. The conductor is a radio frequency (RF) line 200. The power feeding pad 70 and the grounding pad 80 are respectively electrically connected to one end of the RF line 200. Specifically, the RF line 200 may include mutually insulated wire cores and a shielding layer. The power feeding pad 70 is electrically connected to the wire core, and / or the grounding pad 80 is electrically connected to the shielding layer. The shielding layer is conductive. The RF line 200 is prior art, and its specific structure is not illustrated in this application. The other end of the RF line 200 is electrically connected to an IPEX connector 300.

[0065] In some embodiments, the first radiating sheet 10 includes a first radiating body 11 and two first branches 12. The first radiating body 11 has a first branch 12 extending towards the Y-axis at each end along the X-axis. The two first branches 12 are symmetrical about the center of the first radiating body 11. In a preferred embodiment, the two first branches 12 are symmetrical about the central axis of the first radiating body 11, i.e., the Y-axis, and form a resonance in the 6GHz band (5925-7125MHz) of the antenna through the two symmetrical first branches 12. Specifically, the length (along the X-axis) of the first radiating body 11 is 10-20mm and the width (along the Y-axis) is 1-2mm, and the length (along the Y-axis) of the first branch 12 is 2-4mm and the width (along the X-axis) is 1-2mm. In a preferred embodiment of this application, the length (along the X-axis) of the first radiating body 11 is 15 mm and the width (along the Y-axis) is 1.5 mm. The two ends of the first radiating body 11 are flush with the two sides of the substrate 100. The length (along the Y-axis) of the first branch 12 is 3 mm and the width (along the X-axis) is 1.5 mm. The first radiating plate 10 of this application adopts a dipole form. By adjusting the length (along the Y-axis) and width (along the X-axis) of the symmetrical first branch 12, the resonant frequency and bandwidth can be adjusted. That is, the longer the first branch 12, the lower the resonant frequency. This design allows for quantitative adjustment of the resonance frequency in the 5925-7125 MHz range, reducing the antenna size.

[0066] In some embodiments, the first connecting portion 40 is a rectangular structure, with a length (along the X-axis) of 6-8 mm and a width (along the Y-axis) of 4-6 mm. The length of the first connecting portion 40 can be used to adjust the resonance in the 5150-5850 MHz frequency band, and the width of the first connecting portion (40) can be used to adjust the resonance in the 5925-7125 MHz frequency band. Figure 25As shown, when the length of the first connecting portion 40 is reduced, the resonance in the 5150-5850MHz range shifts to higher frequencies; conversely, when the length of the first connecting portion 40 is increased, the resonance shifts to lower frequencies. Similarly, when the width of the first connecting portion 40 is increased, the resonance shifts to lower frequencies; when the width of the first connecting portion 40 is decreased, the resonance in the 5925-7125MHz range shifts to higher frequencies. In a preferred embodiment of this application, the length (along the X-axis) of the first connecting portion 40 is 7mm, and the width (along the Y-axis) is 5mm. In a preferred embodiment of this application, the central axis (along the Y-axis) of the first connecting portion 40 coincides with the central axis (along the Y-axis) of the first radiating body 11.

[0067] In some embodiments, the second radiating sheet 20 includes a second radiating body 21 and two second branches 22. The second radiating body 21 has a second branch 22 extending towards a second end (Y-axis direction) of the substrate 100 at each end along the width direction (X-axis direction) of the substrate 100. The two second branches 22 are symmetrical about the center of the second radiating body 21, that is, the two second branches 22 are symmetrical about the central axis (Y-axis direction) of the second radiating body 21, and the resonance of the antenna in the 5150-5850MHz frequency band is adjusted by the two symmetrical second branches 22. Figure 26 The resonance frequency of 5150-5850MHz can be shifted to a higher frequency by reducing the length of the second stub 22. The second radiating plate 20 in this application is in dipole form, and the resonant frequency and bandwidth of the antenna can be adjusted by adjusting the length (along the Y-axis) and width (along the X-axis) of the second stub 22. Figure 26 Increasing the length or width of the second stub 22 will shift the corresponding resonant frequency band of the antenna to a lower frequency, thereby reducing the antenna size.

[0068] In some embodiments, such as Figure 3 As shown, both the second radiating body 21 and the second branch 22 of this application have a rectangular structure. Both the second radiating body 21 and the second branch 22 include multiple corners. As a preferred embodiment of this application, the two right-angled corners of the second radiating body 21 near the first radiating sheet 10 are beveled, and one corner of the second branch 22 near the third radiating sheet 30 is beveled. The beveled second radiating sheet 20 has a decagonal structure, and the decagonal structure is symmetrical about the center line (along the Y-axis) of the substrate 100. (Refer to...) Figure 2The second radiating plate 20 is shown in the figure. In a preferred embodiment of this application, the length (along the X-axis) of the side of the second radiating plate 20 near the first end of the substrate 100 after beveling is equal to the length (along the X-axis) of the first connecting portion 40, both being 7 mm. After beveling the right-angle corner, the second radiating plate 20 can further widen the resonant width of the antenna. Figure 27 Compared to before the slant cut, the bandwidth of the antenna in the 5150-5850MHz band was significantly widened after the slant cut.

[0069] In some embodiments, the third radiating element 30 of this application is a pentagonal monopole antenna structure with two adjacent right angles, used to adjust the resonance in the 2400-2500MHz frequency band. The two right angles of the third radiating element 30 coincide with the two right angles at the second end of the substrate 100. The apex of the third radiating element 30 (along the negative Y-axis direction) is connected to the second connecting portion 50, and the entire third radiating element 30 is an axisymmetric structure (along the Y-axis direction). This design of the pentagonal monopole antenna structure can improve the bandwidth of the antenna.

[0070] In some embodiments, the second connection portion 50 is a microstrip line, wherein the length (along the Y-axis) and width (along the X-axis) of the microstrip line can be used to adjust the resonant frequency in the 2400-2500MHz frequency band. Figure 28 When the length or width of the microstrip line decreases, the resonance of the antenna in the 2400-2500MHz band shifts significantly to higher frequencies. Conversely, when the length or width increases, the resonance shifts to lower frequencies.

[0071] In some embodiments, the antenna structure of this application can be used in communication terminals, such as audio, video, multimedia or data terminals, specifically, in the form of vehicle antennas.

[0072] like Figures 4 to 14 As shown in the test results of this application, the WiFi 6E antenna has a VSWR of less than 1.5, an efficiency of more than 70%, a gain of more than 2dBi, and good omnidirectionality.

[0073] like Figures 15 to 24 As shown in the test results of this application, when the substrate 100 of this application uses ABS (a graft copolymer of acrylonitrile, 1,3-butadiene, and styrene) material, the WiFi 6E antenna still has good performance.

[0074] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the invention without departing from the principles and spirit of this application, and all such changes should fall within the protection scope of the claims of this application.
