Technical Field

[0001] This utility model relates to the field of communication technology, and in particular to a WIFI antenna and a mobile terminal. Background Technology

[0002] With the continuous development of 5G base station construction, the frequency bands supported by communication terminals are also constantly expanding. Today, mobile phones are commonly used mobile terminal products. With the continuous development of technology, mobile phones inevitably use 5G communication technology, which requires increasing the number of antennas in the phone. However, the space in a mobile phone is limited, and the bandwidth of the antenna is also limited by space, resulting in a limited frequency band coverage and making it difficult to achieve wide bandwidth radiation. In the current context of integrated electronic product structures, antennas face significant environmental challenges. In some harsh environments, higher antenna performance is required, leading to the emergence of new solutions for Wi-Fi antennas.

[0003] In view of this, the present invention provides a novel WIFI antenna and a mobile terminal using the antenna. Utility Model Content

Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the structure of the WIFI antenna of this utility model.

[0018] The labels in the accompanying drawings are explained as follows:

[0019] WIFI antenna 100, first radiating branch 10, second radiating branch 20, antenna branch

[0020] 21, third radiating branch 30, through hole 40, feed point 50, grounding point 60, first gap

[0021] 70, second gap 80. Detailed Implementation

[0022] The WIFI antenna 100 and mobile terminal 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 proportions, 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 have different emphases and sometimes use different proportions.

[0023] This invention provides a WIFI antenna 100, which can be used in mobile phones, tablets, or other types of mobile terminals. The WIFI antenna 100 includes a first radiating stub 10, a second radiating stub 20, and a third radiating stub 30 coupled to the first and second radiating stubs 10 and 20 respectively. The first radiating stub 10 is connected to the second radiating stub 20, and a feed point 50 is electrically connected to the first radiating stub 10. A ground point 60 is electrically connected to the second radiating stub 20. The first radiating stub 10 and the second radiating stub 20 extend to opposite sides of the feed point 50 and the ground point 60, respectively. The third radiating stub 30 is coupled to the second radiating stub 20 to form a coupling gap.

[0024] With this configuration, the WIFI antenna 100 of this invention not only simplifies the overall antenna design and wiring structure, but also enables the antenna to achieve a relatively wide resonance range even in harsh environments, and effectively improves the overall performance of the antenna.

[0025] Further, the first radiating stub 10 is quarter-circle shaped, the second radiating stub 20 is configured as an FIA antenna, and the third radiating stub 30 is configured as a C-shaped antenna. The first radiating stub 10, the second radiating stub 20, and the third radiating stub 30 are interconnected to form a third-circle shaped WIFI antenna 100. A first gap 70 and a second gap 80 are formed between the first radiating stub 10 and the second radiating stub 20, with the width of the first gap 70 being larger than the width of the second gap 80. A through-hole 40 is provided on the first radiating stub 10, and the feed point 50 and the ground point 60 are respectively provided between the second gaps 80. The second radiating stub 20 includes an antenna stub 21, which is half-circle shaped. Both the second gap 80 and the antenna stub 21 are configured to control the 5G WIFI frequency band. The antenna stub 21 is located to the right of the grounding point 60. The longer the antenna stub 21, the narrower the bandwidth of the 5G WIFI. The third radiating stub 30 is attached to the same horizontal plane as the first radiating stub 10 and the second radiating stub 20. The length of the WIFI antenna 100 is 50mm ± 0.01.

[0026] In other words, the second slot 80 and the antenna stub 21 mainly control the bandwidth and length of the 5G frequency band; if the length of the second slot 80 between the ground feeders and the length of the 5G trace are too long, the efficiency of 5.8G will be worse; if the slot length of the ground feeder diameter is too small, it will lead to a narrower 5G bandwidth and a decrease in overall performance; the length of the 5G antenna is adjusted by adjusting the position and length of the antenna stub 21. The longer the stub, the longer the 5G WIFI, but as the length increases, the bandwidth of 5G will become narrower.

[0027] The third radiating stub 30 is configured as a floating antenna. The resonant length resulting from coupling with the original wiring is controlled by adjusting the length of the floating antenna, thereby improving the performance and bandwidth of 5G Wi-Fi. The floating antenna and the antenna body are on the same horizontal plane and are attached to the decorative parts of the mobile terminal. The first radiating stub 10 mainly controls the length of the 2.4G Wi-Fi; the length of the 2.4G Wi-Fi is adjusted by changing the length of the antenna at this point. From the wiring design of this invention, this antenna occupies a relatively large area and is longer than conventional 2.4G antennas. In terms of antenna layout, antenna performance is improved by utilizing the remaining available antenna space to add floating stubs.

[0028] In summary, this utility model provides a WIFI antenna 100 and a mobile terminal. The WIFI antenna 100 includes a first radiating stub 10, a second radiating stub 20, and a third radiating stub 30 coupled to the first radiating stub 10 and the second radiating stub 20. The first radiating stub 10 is connected to the second radiating stub 20, and a feed point 50 is electrically connected to the first radiating stub 10. The second radiating stub 20 is electrically connected to a ground point 60. The first radiating stub 10 and the second radiating stub 20 extend to opposite sides of the feed point 50 and the ground point 60, respectively. The third radiating stub 30 is coupled to the second radiating stub 20 to form a coupling gap. The WIFI antenna 100 of this utility model not only simplifies the overall antenna design and wiring structure but also enables the antenna to achieve a relatively wide resonance range even in harsh antenna environments, effectively improving the overall performance of the antenna.
