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

[0020] Full-band antenna 100, first radiating antenna 10, first radiating stub 11, second radiating stub 12, first slot 13, second slot 14, second radiating antenna 20, feed point 30, first grounding point 40, second grounding point 41. Detailed Implementation

[0021] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates the full-band antenna 100 and the mobile terminal using this antenna according to the present invention. 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 the present invention. 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.

[0022] The primary antenna in a wireless communication system is mainly used for transmitting and receiving signals. The NFC antenna exchanges data with other NFC devices over short distances via electromagnetic induction. In smartphones, the primary antenna can be used for long-distance communication, while the NFC shared antenna enables near-field communication applications such as mobile payments and data transfer. Together, they provide different communication functions for the device, such as mobile payments and data transfer.

[0023] This invention provides a full-band antenna 100, which can be used in various mobile terminals, such as mobile phones, tablets, and laptops. The full-band antenna 100 includes a first radiating antenna 10, a second radiating antenna 20, a feed point 30, and a grounding component. The first radiating antenna 10 and the second radiating antenna 20 are interconnected. The first radiating antenna 10 includes a first radiating stub 11 and a second radiating stub 12 connected to the first radiating stub 11. A first gap 13 is formed between the second radiating stub 12 and the first radiating stub 11. The second radiating stub 12 is located beside and connected to the first radiating stub 11. The second radiating antenna 20 extends in the opposite direction to the first gap 13. That is, the second radiating antenna 20 extends towards the right side of the first radiating antenna 10.

[0024] With this design, the full-band antenna 100 of this invention not only saves space for the overall antenna wiring, but also effectively improves the overall radiation performance of the antenna. Furthermore, the integrated design effectively reduces the number of antennas and the complexity of manufacturing, thereby reducing production costs.

[0025] Preferably, the first radiating stub 11 and the second radiating stub 12 form a U-shape, and the first gap 13 is aligned with the U-shaped groove formed by the first radiating stub 11 and the second radiating stub 12. Preferably, the first radiating antenna 10 is configured as a master antenna, and the second radiating antenna 20 is configured as an NCF antenna. This configuration integrates the two antenna functions, saving internal space in the mobile terminal and providing more layout possibilities for other components. This is especially important for modern mobile terminals that prioritize thinness and lightness, particularly the commonly used mobile phones. Furthermore, in terms of performance optimization, careful design and optimization can achieve good collaborative operation of the master and NFC functions without affecting their respective functional performance. In addition, costs can be reduced; the integrated design reduces the number of antennas and manufacturing complexity, not only lowering production costs but also broadening the overall antenna frequency band.

[0026] Further, the extension directions of the first radiating stub 11 and the second radiating stub 12 are opposite to the extension direction of the second radiating antenna 20. The first radiating stub 11 is located above the second radiating stub 12. The end of the second radiating stub 12 extends in a direction perpendicular to the first slot 13, and the second radiating stub 12 and the first radiating stub 11 form an angled region, which is connected to the first slot 13. Further, the grounding assembly includes a first grounding point 40 and a second grounding point 41. The feed point 30 is located between the first grounding point 40 and the second grounding point 41, and a second slot 14 is formed between the first grounding point 40 and the feed point 30. The feed point 30 is electrically connected to the first radiating antenna 10, the first grounding point 40 is electrically connected to the first radiating antenna 10, and the second grounding point 41 is electrically connected to the second radiating antenna 20.

[0027] In this invention, the length of the full-band antenna 100 ranges from 55.06 mm ± 0.01 mm, and the width ranges from 14.38 mm ± 0.01 mm. The width of the first slot 13 ranges from 0.40 mm ± 0.01 mm, and the width of the second slot 14 ranges from 0.65 mm ± 0.01 mm. Specifically, traditional wiring and debugging methods are often limited and struggle to meet all performance requirements. In this invention, the radiator between the feed point 30 and the second grounding point 41 is defined as the common antenna. By adding the common antenna, the far leg of the added second grounding point 41 has its impact on the overall antenna design reduced through matching design. This effectively adds an adjustable form to the main antenna design, moving away from the single-performance limitations of traditional wiring. Utilizing the added grounding point in the wiring design, any connection formed on the antenna can be modified by changing the connection point position, length, line width, and spacing to achieve different performance requirements. This, combined with antenna debugging, effectively improves the performance of the main antenna. Furthermore, the full-band antenna 100 of this invention, along with its matching circuit design, ensures that signals do not interfere with each other, while maintaining high efficiency and sensitivity, as well as low SAR performance.

[0028] In summary, this utility model provides a full-band antenna 100 and a mobile terminal. The full-band antenna 100 includes a first radiating antenna 10, a second radiating antenna 20, a feed point 30, and a grounding component. The first radiating antenna 10 and the second radiating antenna 20 are interconnected. The first radiating antenna 10 includes a first radiating stub 11 and a second radiating stub 12 connected to the first radiating stub 11. A first gap 13 is formed between the second radiating stub 12 and the first radiating stub 11. The second radiating stub 12 is located beside the first radiating stub 11 and is connected to the first radiating stub 11. The second radiating antenna 20 extends in the opposite direction to the first gap 13. The full-band antenna 100 of this invention not only saves space in the overall antenna wiring, that is, it can integrate two functional antennas together, saving internal space in the mobile terminal and providing more layout possibilities for other components; it also effectively improves the overall radiation performance and radiation frequency band of the antenna, that is, it can achieve good collaborative work between the main unit and NFC functions without affecting their respective functional performance, thus broadening the overall radiation frequency band of the antenna. Moreover, the integrated design can effectively reduce the number of antennas and the complexity of manufacturing, thereby reducing production costs.
