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

[0021] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed account of the dual-band WiFi antenna proposed in this utility model and the mobile terminal electronic device using this 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.

[0022] Currently, mobile terminal devices are favored by users for their intelligent and slim designs. However, with the iterative development of intelligence and slimness, the antenna design within these devices has become more complex, leading to poor overall antenna communication performance. In particular, complex antenna wiring weakens the anti-interference capabilities of individual antennas. Antenna anti-interference capability is mainly reflected in its design and technological applications to reduce the impact of external interference on signal reception and transmission. Typically, additional electronic components are added to the design, such as anti-interference sensors. Built-in sensors can effectively suppress electromagnetic interference from the ground and surrounding environment, improving signal reception stability and reliability. For example, by setting up an array antenna to allocate different amplitudes and phases, the desired radiation pattern can be synthesized, achieving effects such as low sidelobes and high gain. Each element in the anti-interference antenna array corresponds to a radio frequency channel, working independently and processing the received signal. Furthermore, setting antenna polarization methods or adding impedance matching, etc., all increase the overall antenna design complexity and correspondingly increase production costs.

[0023] like Figure 1As shown, this utility model provides a dual-band WiFi antenna that can be applied to mobile terminal electronic devices, such as mobile phones, tablets, and VR smart glasses. The dual-band WiFi antenna includes a feed point 80, a ground point 90, a first radiating stub 10, a second radiating stub 20, and a third radiating stub 30. The first radiating stub 10, the second radiating stub 20, and the third radiating stub 30 are connected sequentially. A first gap 50 is formed between the first radiating stub 10 and the second radiating stub 20, and a second gap 60 is formed between the second radiating stub 20 and the third radiating stub 30. The feed point 80 is electrically connected to the second radiating stub 20, and the ground point is electrically connected to the first radiating stub 10. The dual-band WiFi antenna of this utility model is fed via a cable connecting the feed point 80 and the ground point 90. Of course, other forms of feeding can also be used, and this utility model does not impose any limitations.

[0024] This configuration effectively improves the overall anti-interference capability of the dual-band WiFi antenna and broadens its overall bandwidth, thereby enhancing the user experience of mobile terminal electronic devices. In other words, compared to existing technologies, utilizing a slotted coupling method improves the anti-interference capability of the dual-band WiFi antenna and effectively broadens its overall radiation bandwidth, solving the problem of weak anti-interference capability in mobile terminal electronic devices and significantly improving the user experience.

[0025] Furthermore, the dual-band WiFi antenna also includes a fourth radiating stub 40, which is connected to the third radiating stub 30, and forms a third gap 70 with the second radiating stub 20. The third gap 70 communicates with the second gap 60. Preferably, the width of the first gap 50 is smaller than the width of the second gap 60, and the width of the second gap 60 is smaller than the width of the third gap 70. Preferably, the first radiating stub 10, the second radiating stub 20, and the third radiating stub 30 are all configured as patch antennas. Of course, the above-mentioned radiating stubs can also be configured as LDS antennas, PDS antennas, etc., and this utility model does not impose any limitations.

[0026] Preferably, the first radiating stub 10 has a U-shaped groove at its end near the first gap 50, and the U-shaped groove communicates with the first gap 50. The first gap 50 is configured to control a radiation frequency band of 5150MHz-5850MHz. The fourth radiating stub 40 and the third radiating stub 30 are configured to control a radiation frequency band of 2400MHz-2500MHz. The first radiating stub 10 is configured to control a radiation frequency band of 2400MHz, and the second radiating stub 20 is coupled to the fourth radiating stub 40.

[0027] Combination Figure 2 As shown, the first slot 50 can control the bandwidth and resonance within the 5100MHz-5850MHz frequency band. A 1mm sealed slot will result in a slightly higher antenna resonance, while an open slot will result in a lower resonance. The fourth radiating stub 40 can control the 2400MHz-2500MHz frequency band, specifically the resonance generated through coupling between the fourth radiating stub 40 and either the second radiating stub 20 or the first radiating stub 10. The first radiating stub 10 is highly sensitive to the 2400MHz band and also controls the depth of the 5G S11. Shortening the fourth radiating stub 40 by 1mm will result in a higher overall 2.4G antenna resonance; conversely, lengthening it by 1mm will result in a lower overall antenna resonance and a significant change in Smith impedance. Depending on the requirements, the size of the radiating stubs and the spacing between them can be adjusted to change the coupling resonance.

[0028] In summary, this utility model provides a dual-band WiFi antenna and a mobile terminal electronic device. The dual-band WiFi antenna includes a feed point 80, a ground point 90, a first radiating stub 10, a second radiating stub 20, and a third radiating stub 30. The first radiating stub 10, the second radiating stub 20, and the third radiating stub 30 are connected sequentially. A first gap 50 is formed between the first radiating stub 10 and the second radiating stub 20, and a second gap 60 is formed between the second radiating stub 20 and the third radiating stub 30. The feed point 80 is electrically connected to the second radiating stub 20, and the ground point is electrically connected to the first radiating stub 10. This dual-band WiFi antenna effectively improves the overall anti-interference capability of the antenna and also effectively widens the overall bandwidth of the antenna, thereby enhancing the user experience of the mobile terminal electronic device. In other words, compared with existing technologies, the anti-interference capability of WiFi dual-band antennas can be improved by using the slotted coupling method. In addition, it can effectively broaden the overall radiation bandwidth of the antenna, solve the problem of weak anti-interference capability on mobile terminal electronic devices, and effectively improve the customer experience.
