Description

Technical Field

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

[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] Throughout history, humanity's pursuit of beauty has never ceased, flowing like a never-ending river. From the flowing ribbons of the Dunhuang flying apsaras to the solitary light of the space station, transcendence has always been the most moving narrative. Mobile phone designs are constantly evolving, and antenna designs are becoming increasingly complex, while the performance indicators of antenna signal transmission and reception remain consistently high. The exploration of even better mobile phone antenna designs continues. Today, with the segmentation of complex mobile phone antenna frequency bands, the evolution of mobile phone antenna design has, in a rich and diverse manner, completed a silent dialogue of civilization within modern technology.

[0004] However, mobile phone antenna radiation is significantly affected by height, clearance, and area. Optimizing multi-band antennas often compromises these factors, resulting in more harm than good. Previous designs similar to this proposal often resulted in excessive antenna contact, or even complete contact, leading to high isolation between antennas and consequently, severe mutual interference that reduced antenna performance. Such adjustments often involved adding parallel or series LC circuits to filter out noise, but the effect of reducing mutual interference was often imperfect, and the circuits often introduced self-oscillation, leading to a decline in antenna performance.

[0005] In view of this, it is indeed necessary to propose a full-band antenna and a mobile terminal using the antenna. Utility Model Content

[0022] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the full-band antenna proposed in this utility model and the mobile terminal using this full-band antenna. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, intended only 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 emphasize different aspects and sometimes use different proportions.

[0023] Users' pursuit of beauty has never ceased, flowing like a never-ending river. From the flowing ribbons of the Dunhuang flying apsaras to the arc of light on the space station, transcendence remains the most moving narrative. As the most popular timekeeping device of the new era, the mobile phone marks the spiritual agricultural season for modern people with push notifications, recalculates the ecliptic plane of interpersonal relationships with location coordinates, and predicts the tides of urban desires with algorithms. The exquisite designs of mobile phones are constantly evolving, and the antenna designs on them are becoming increasingly complex, while the performance indicators of antenna signal transmission and reception remain consistently high. Even better mobile phone antenna design solutions are constantly being explored, such as splitting the complex frequency bands of mobile phone antennas. The evolution of mobile phone antenna design, in its rich and varied forms, has completed a silent dialogue of civilization within modern technology.

[0024] However, mobile phone antenna radiation is significantly affected by height, clearance, and area. Optimizing multi-band antennas often results in trade-offs and is ultimately counterproductive. To improve antenna performance, it is necessary to split the antenna frequency band. This splitting does not mean abandoning the band, but rather dividing it into several sub-bands for tuning. This undoubtedly achieves better tuning results. This proposal presents a new design concept for single-band antennas. Previous designs similar to this one often resulted in large contact areas between the two antennas, or even complete contact, leading to high isolation between the antennas and severe mutual interference, which reduced antenna performance. Such tuning often involves adding parallel or series LC circuits to filter clutter, but the mutual interference reduction effect is often imperfect. LC circuits also often introduce "self-oscillation" phenomena, leading to a decrease in antenna performance. This proposal abandons the drawbacks of traditional tuning schemes and develops a new design approach. The full-band antenna of this utility model is significantly different from the original design and also has certain advantages.

[0025] This utility model provides a full-band antenna, which includes a first radiating element, a second radiating element, a ground point b, a first feed point a, and a second feed point c. The first radiating element and the second radiating element are electrically connected to the ground point b, the first feed point a, and the second feed point c. The first radiating element and the second radiating element are connected by a connector d, one end of which is connected to the first radiating element and the other end of which is connected to the second radiating element. A gap region is formed between the first radiating element and the second radiating element.

[0026] With this configuration, the full-band antenna of this invention not only effectively improves the overall radiation efficiency of the antenna, but also broadens the overall radiation bandwidth. In other words, compared to traditional solutions, it increases the overall bandwidth of the antenna band for 2.4G WiFi, effectively improving the overall radiation efficiency of the antenna and resulting in a 1dB improvement in the overall signal transmission and reception performance.

[0027] Furthermore, the spacing of the gap region in the horizontal direction ranges from [1.7, 1.8] mm. This setting further optimizes the performance of the full-band antenna, ensuring its stability and efficiency across different frequency bands. Precise control of the gap region reduces mutual interference between antennas, improves antenna isolation, and thus enhances the overall performance of the antenna.

[0028] In practical implementation, precise control of the gap region can be achieved by adjusting the length and shape of the connector d, as well as the structure of the first and second radiating elements. Simultaneously, factors such as the selection of antenna materials and processing precision must be considered to ensure that the actual performance of the antenna matches the theoretical design.

[0029] Furthermore, the full-band antenna of this invention can be optimized in other ways. For example, more slots or gaps can be provided on the first and second radiating elements to further broaden the antenna's radiation bandwidth. Alternatively, more advanced manufacturing processes and materials can be used to improve the antenna's radiation efficiency and stability. The full-band antenna of this invention and the mobile terminal using this antenna achieve a significant improvement in antenna performance through a novel design concept and optimized structure. This antenna not only has a wide radiation bandwidth and high radiation efficiency but also high stability and reliability, and can be widely used in various mobile terminal devices to meet people's needs for high-speed and stable communication.

[0030] Specifically, the first radiating element includes a first antenna stub g, a second antenna stub g1, and a third antenna stub g2 connected to each other. The second antenna stub g1 and the third antenna stub g2 are both located on one side of the first antenna stub g. The second antenna stub g1 and the third antenna stub g2 are both located to the left of the first feed point a, and are parallel to each other. The first antenna stub g is electrically connected to the first feed point a, and has several slots located above the first feed point a.

[0031] Furthermore, the second radiating element includes a fourth antenna stub f1, a fifth antenna stub f, and a sixth antenna stub f2 connected in sequence. The fourth antenna stub f1 is electrically connected to the grounding point b and the second feed point c. One end of the fifth antenna stub f is connected to the fourth antenna stub f1, and the other end of the fifth antenna stub f is connected to the sixth antenna stub f2. Positioning holes are provided on the fifth antenna stub f, all located above the fourth antenna stub f1. A first slot h is provided on the sixth antenna stub f2. A second slot p is formed by sequentially connecting the fifth antenna stub f, the fourth antenna stub f1, and the sixth antenna stub f2. The first slot h and the second slot p are connected. The first slot h is rectangular, and the second slot p is L-shaped. This configuration further optimizes the performance of the full-band antenna, enabling better matching and radiation effects in different frequency bands. Specifically, the connection between the first slot h and the second slot p helps adjust the current distribution of the antenna, thereby improving its radiation characteristics. The rectangular first slit h and the L-shaped second slit p work together to achieve precise control over the antenna's radiation direction, thereby improving the antenna's directivity and gain.

[0032] Furthermore, the design of the positioning holes plays a crucial role. These holes not only secure and mount the antenna but also influence its electromagnetic field distribution. By rationally setting the position and number of positioning holes, antenna performance can be further optimized, ensuring good communication performance in various environments. In practical implementation, the antenna structure can be adjusted and optimized according to actual needs. For example, the length, width, and shape of antenna stubs can be changed to adjust the antenna's resonant frequency and radiation bandwidth. Alternatively, the size, shape, and position of slots and gaps can be adjusted to modify the antenna's radiation characteristics and directivity. Simultaneously, factors such as the selection of antenna materials, processing precision, and installation methods must be considered to ensure that the actual performance of the antenna matches the theoretical design.

[0033] In summary, the full-band antenna and mobile terminal using this antenna provided by this utility model achieve a significant improvement in antenna performance through a novel design concept and optimized structure. This antenna not only has a wide radiation bandwidth and high radiation efficiency, but also high stability and reliability, making it widely applicable in various mobile terminal devices to meet people's needs for high-speed and stable communication. This utility model provides a full-band antenna comprising a first radiating element, a second radiating element, a ground point b, a first feed point a, and a second feed point c. Both the first and second radiating elements are electrically connected to the ground point b, the first feed point a, and the second feed point c. The first and second radiating elements are connected via a connector d, with one end of the connector d connected to the first radiating element and the other end connected to the second radiating element. A gap region is formed between the first and second radiating elements. This full-band antenna not only effectively improves the overall radiation efficiency of the antenna but also widens the overall radiation bandwidth.
