[0002] With the continuous development of 5G base station construction, the frequency bands supported by communication terminals are also constantly expanding. Nowadays, 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 mobile phones. However, the space in mobile phones is limited, and the bandwidth of antennas is also limited by space, so the frequency bands covered by the antennas are limited, making it difficult to achieve the wide bandwidth radiation of the antennas.

[0003] With the rapid development of mobile communication technology, mobile communication technology, as a key component of wireless communication, has evolved from simple to complex. In the 5G era, mobile phone antenna technology has faced unprecedented challenges. 5G networks, with their high speed, large capacity, and low latency, have brought revolutionary changes to mobile communication. 5G mobile phones not only need to support higher frequency bands to meet the communication needs of different operators and regions, but also face the challenges of miniaturization, integration, and multi-band support. Although mobile phone antenna technology has made rapid progress in the 5G era, it still has shortcomings. First, 5G mobile phones are very sensitive to surrounding metal. Mobile phones pursue miniaturization and thinness, but miniaturization often leads to a decrease in antenna performance. How to achieve miniaturization while maintaining antenna performance is a difficult technical problem.

[0004] In view of this, it is indeed necessary to propose a high-performance terminal antenna and a mobile terminal using the high-performance terminal antenna. Utility Model Content

[0018] Figure 1 This is a schematic diagram of the structure of the high-performance terminal antenna of this utility model.

[0019] The labels in the accompanying drawings are explained as follows:

[0020] First radiating branch 10, first gap 11, second radiating branch 20, second gap 21, third radiating branch 30, third gap 31, first support 310, second support 311, first slot 312, second slot 313, feed point 40, grounding point 50. Detailed Implementation

[0021] The high-performance terminal antenna proposed in this utility model and the mobile terminal using this terminal antenna 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 proportions may be used in different drawings to illustrate different aspects.

[0022] This invention provides a high-performance terminal antenna that can be used in mobile terminals, such as mobile phones, tablets, or laptops.

[0023] This utility model provides a high-performance terminal antenna, which includes a feed point 40, a ground point 50, a first radiating stub 10, a second radiating stub 20, and a third radiating stub 30. The feed point 40 is electrically connected to the first radiating stub 10, and the ground point 50 is electrically connected to the third radiating stub 30. The second radiating stub 20 and the first radiating stub 10 extend in the same direction, while the third radiating stub 30 extends in the opposite direction. The first radiating stub 10 has a first slot 11, the second radiating stub 20 has a second slot 21, and the third radiating stub 30 has a third slot 31. The first slot 11, the second slot 21, and the third slot 31 are independent of each other.

[0024] With this configuration, the high-performance terminal antenna of this invention not only effectively improves the overall anti-interference capability of the antenna, but also effectively widens the overall bandwidth of the antenna, enhancing the user experience. In other words, compared with existing technologies, it achieves improved anti-interference capability across the entire frequency band and effectively widens the overall bandwidth of the antenna, thereby greatly enhancing the customer experience.

[0025] Specifically, the first radiating stub 10 is connected to the second radiating stub 20, and the connection between the first radiating stub 10 and the second radiating stub 20 forms a V-shape. The first radiating stub 10 and the second radiating stub 20 are arranged in a V-shape or V-shape, with the opening angle controlled between 60° and 120°. This angle parameter, after simulation optimization, can achieve optimal impedance matching in both the 2.4GHz and 5.8GHz dual-band frequencies, thereby effectively widening the operating bandwidth.

[0026] Furthermore, the third slot 31 on the third radiating stub 30 includes a first slot 312 and a second slot 313, which are arranged perpendicularly. This arrangement effectively enhances the dual-polarization characteristics, as the vertically arranged slots can support both horizontal and vertical polarization respectively, achieving polarization diversity. This design can effectively reduce signal attenuation caused by polarization mismatch, especially improving communication stability in multipath environments.

[0027] The third radiating branch 30 is configured in an L-shape. The third radiating branch 30 includes a first leg 310 and a second leg 311, with the first leg 310 and the second leg 311 being perpendicular to each other. A first slot 11 is formed on the first radiating branch 10, the first slot 11 being annular, and one end of the first slot 11 being connected to the feed point 40.

[0028] The first support 310 has several small holes spaced apart. The second support 311 has a second slot 313, and the grounding point 50 is electrically connected to the second support 311. The second radiating stub 20 has a second slot 21 extending along its length. Specifically, the third radiating stub 30 is configured to control the resonance in the 617MHz-960MHz and 1710MHz-2690MHz frequency bands. The third slot 31 controls the low-frequency resonance. The first radiating stub 10 has a significant impact on the high-frequency radiation, controlling the high-frequency resonance and bandwidth. If the planar length of the third radiating stub 30 is shortened by 0.5mm, the overall intermediate frequency resonance of the antenna will be higher, and the overall low-frequency resonance will be lower. In addition, the third slot 31 on the third radiating stub 30 also greatly helps to improve the intermediate frequency bandwidth. Thus, adjusting the length of each branch and the spacing of the slots on the branches according to actual needs will also produce changes in coupling resonance.

[0029] In summary, this utility model provides a high-performance terminal antenna and a mobile terminal using the antenna. The high-performance terminal antenna includes a feed point 40, a ground point 50, a first radiating stub 10, a second radiating stub 20, and a third radiating stub 30. The feed point 40 is electrically connected to the first radiating stub 10, and the ground point 50 is electrically connected to the third radiating stub 30. The second radiating stub 20 extends in the same direction as the first radiating stub 10, while the third radiating stub 30 extends in the opposite direction. The first radiating stub 10 has a first slot 11, the second radiating stub 20 has a second slot 21, and the third radiating stub 30 has a third slot 31. The first slot 11, the second slot 21, and the third slot 31 are independent of each other. This high-performance terminal antenna not only effectively improves the overall anti-interference capability of the antenna but also effectively widens the overall bandwidth, enhancing the user experience.
