For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0029] Referring to Figures 1-4 The application provides a three-in-one antenna, comprising a substrate 1 and an antenna main body arranged on the substrate 1, the antenna main body comprising a first branch 2, a second branch 3, a third branch 4, a feeding point 5 and a ground point 6, the first branch 2 and the second branch 3 are connected with the third branch 4, the feeding point 5 and the ground point 6 are arranged at intervals on the first branch 2, a coupling groove 7 is arranged between the first branch 2 and the second branch 3, and the groove width of the coupling groove 7 is 0.90mm-1.50mm.

[0030] The three-in-one antenna of the application has simple wiring and is easy to implement and has strong practicability. Through the multiple branches, the antenna can support multiple working frequency bands, and can simultaneously meet the requirements of Bluetooth, 2.4G WiFi and 5G WiFi. Through the design of multiple antenna branches, multiple antenna functions can be integrated in a small space. Through optimization of the coupling between the parts of the antenna, the working efficiency of the antenna is improved, and energy loss is reduced. The antenna using the substrate and branch structure is relatively easy to manufacture, can be realized through printed circuit board technology, has low cost and high production efficiency. Due to the multi-band support capability and good design flexibility, the antenna of the application can be widely applied to various wireless communication devices, and has wide applicability from consumer electronic products to industrial applications.

[0031] Specifically, the groove width of the coupling groove 7 is 0.90mm-1.50mm. The width of the groove between the first branch 2 and the second branch 3 will affect the length of the 2.4G and 5G waveforms. When the groove width of the coupling groove 7 is narrow, the electromagnetic field coupling is strong, which may cause high mutual coupling effect, thereby affecting the isolation of the antenna. When the coupling is too strong, it may cause the performance of the antenna to decrease in some frequency bands. When the coupling groove 7 is wide, the coupling between the adjacent branches is weak, which helps to improve the isolation of the antenna and reduce the mutual interference between different frequency bands. However, if the coupling is too weak, it will affect the overall performance of the antenna.

[0032] Specifically, the first branch 2 and the second branch 3 are arranged at least partially in parallel. The parallel arrangement of the branches can enhance the electromagnetic coupling between them, and this enhanced coupling helps to improve the performance of the antenna, especially in multi-band operation, better interaction between frequency bands can be achieved, improving the overall efficiency and bandwidth of the antenna; reduces the complex design steps, making the antenna easier to understand and optimize, while also facilitating manufacturing and debugging; helps to optimize the input impedance of the antenna, making it easier to match with the feed line. This can reduce the reflection loss, improve the efficiency and transmission performance of the antenna; saves space, making the overall layout of the antenna more compact, which can improve the integration and portability of the device.

[0033] Further, the coupling slot 7 is a straight line type coupling slot. The width and length of the straight line type coupling slot can be accurately controlled, thereby accurately adjusting the coupling strength between adjacent branches. By adjusting the slot width and length, the coupling effect of the antenna can be optimized to ensure the desired performance at different frequency bands; the design is relatively simple and easy to understand and implement. This simple geometry makes the design and simulation process of the antenna more intuitive and efficient, reducing the complexity of the design and the possibility of errors; can reduce manufacturing difficulty and cost, improve production efficiency and yield.

[0034] In some embodiments, the first branch 2 covers the 5G WiFi frequency band; the second branch 3 covers the 2.4G WiFi frequency band; and the third branch 4 covers the 5G WiFi frequency band. When the current flows through the feed point 5 to the second branch 3 to produce a 2.4G resonance of 2400-2500MHz, through the first branch 2 to produce a 5G resonance of 5150-5850MHz, and through the third branch 4 to also produce a 5G resonance of 5150-5850MHz, the two 5G resonances of the first branch 2 and the third branch 4 work together to form a complete and efficient 5G resonance.

[0035] In some embodiments, the length of the first branch 2 is 10.77-11.37mm; the length of the second branch 3 is 10.40-11.00mm; and the length of the third branch 4 is 4.86-5.46mm. The length of the second branch 3 will affect the length of the 2.4G and 5G waveforms, and when the second branch 3 is too long, it will cause some interference to the adjacent antenna. The length of the third branch 4 will also affect the length of the 2.4G and 5G waveforms, and when the third branch 4 is too short, the 2.4G and 5G efficiency will be low, and when the third branch 4 is too long, the antenna will be coupled with the adjacent antenna, affecting the 5G of the antenna and reducing the performance of the antenna. The first branch 2 mainly functions to control the length of 5G and synthesize a higher efficiency 5G wave with the 5G wave of the third branch 4, and the first branch 2 has little effect on the 2.4G generated by the second branch 3.

[0036] In an embodiment, the back surface of the substrate 1 is provided with a back adhesive, thereby facilitating its connection and installation.

[0037] In an embodiment, the application also provides a wireless communication device, which comprises the three-in-one antenna provided in the above embodiments.

[0038] The above embodiments are only used to illustrate the technical solutions of the application, and not to limit the protection scope of the application.
