Description

Technical Field

[0001] This utility model relates to the field of communication technology, and in particular to a novel dual-band WiFi antenna and 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. 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] In addition, the demand for smart products is increasing, with higher requirements for network speed, stability, high throughput, and directionality. Currently, traditional WiFi antennas have poor directionality, resulting in insufficient throughput. They are usually designed with a large number of antennas, which cannot simultaneously cover WiFi 2.4G and 5G, and there are also problems such as poor consistency.

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

[0018] Figure 1 This is a schematic diagram of the structure of the novel dual-band WiFi antenna of this utility model.

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

[0020] Dual-band WiFi antenna 100, first radiating branch 10, second radiating branch 20, feed point 30, grounding point 40, groove 50. Detailed Implementation

[0021] The novel dual-band WiFi antenna 100 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 proportions may be used in different drawings to illustrate different aspects.

[0022] This utility model provides a novel dual-band WiFi antenna 100, which can be applied to mobile terminals, such as smartphones, tablets, or other smart mobile terminals.

[0023] Specifically, the novel dual-band WiFi antenna 100 includes a feed point 30, a ground point 40, a first radiating stub 10, and a second radiating stub 20. A groove 50 is formed between the first radiating stub 10 and the second radiating stub 20. The first radiating stub 10 and the second radiating stub 20 are located on both sides of the groove 50. The feed point 30 and the ground point 40 are both electrically connected to the first radiating stub 10. The first radiating stub 10 is located directly above the feed point 30, and the second radiating stub 20 is located obliquely above the feed point 30. The groove 50 is located obliquely above the feed point 30.

[0024] This design not only simplifies the overall antenna design but also effectively expands the overall antenna bandwidth. In other words, the dual-band WiFi antenna 100 of this invention not only solves the overall antenna bandwidth problem but also simplifies the overall antenna wiring design, eliminating the need for multiple WiFi antennas to cover different frequency bands on mobile terminals.

[0025] Furthermore, the novel dual-band WiFi antenna 100 also includes a substrate, on which both the first radiating stub 10 and the second radiating stub 20 are disposed. Furthermore, both the first radiating stub 10 and the second radiating stub 20 are configured as FPC antenna stubs. Of course, the first radiating stub 10 and the second radiating stub 20 can also be configured as other antenna types, such as LDS antennas.

[0026] Furthermore, the first radiating stub 10 is located directly above the feed point 30 to form an IFA stub antenna, and the first radiating stub 10 is T-shaped. Further, the first end of the first radiating stub 10 is a free end, the second end of the first radiating stub 10 is electrically connected to the feed point 30 and the ground point 40, and the third end of the first radiating stub 10 is connected to the second radiating stub 20. That is, the first radiating stub 10 is located directly above the feed point 30, forming an IFA mode, which can excite WiFi 5G resonance with a relatively wide bandwidth according to the principle of antenna electrical length. The second radiating stub 20 is located diagonally above the feed point 30, also forming an IFA mode, which can select a reasonable physical length to excite WiFi 2.4G resonance according to the quarter-wavelength principle of 2.4G electrically small antennas. Simultaneously, depending on the debugging situation, a gap can be opened between the feed point 30 and the ground point 40 to expand the antenna width.

[0027] Furthermore, the second radiating stub 20 is L-shaped, and one end of the second radiating stub 20 is connected to the third end of the first radiating stub 10 to form the groove 50. Furthermore, a gap is formed between the feed point 30 and the ground point 40 to extend the antenna bandwidth. Furthermore, a through-hole is formed on the substrate, and the through-hole is located within the groove 50. Furthermore, positioning holes are also formed on the substrate, and some of the positioning holes are located on the first radiating stub 10 and the second radiating stub 20.

[0028] The groove 50 formed between the first radiating stub 10 and the second radiating stub 20 of the dual-band WiFi antenna 100 of this invention can further widen the antenna bandwidth, enabling the antenna to simultaneously cover WiFi 2.4G and WiFi 5G. A gap is formed between the feed point 30 and the ground point 40, allowing for wider bandwidth expansion according to customer customization needs. Positioning holes are formed on the substrate, with some of these holes located on the first radiating stub 10 and the second radiating stub 20. This effectively adjusts the antenna frequency offset and improves the antenna's radiation efficiency. Furthermore, the dual-band WiFi antenna 100 of this invention can adjust the traditional antenna wiring, simplifying the complex antenna design, reducing the number of antennas, and also making the antenna radiation modes clearer and the radiation performance more stable.

[0029] In summary, this utility model provides a novel dual-band WiFi antenna 100 and a mobile terminal. The novel dual-band WiFi antenna 100 includes a feed point 30, a ground point 40, a first radiating stub 10, and a second radiating stub 20. A groove 50 is formed between the first radiating stub 10 and the second radiating stub 20, located on both sides of the groove 50. The feed point 30 and the ground point 40 are both electrically connected to the first radiating stub 10. The first radiating stub 10 is located directly above the feed point 30, and the second radiating stub 20 is located diagonally above the feed point 30. The groove 50 is also located diagonally above the feed point 30. This utility model not only simplifies the overall antenna design but also effectively widens the overall bandwidth of the antenna.
