Description

Technical Field

[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.

In many project debugging processes, the performance of free-space calls is easily met, but the performance of simulated handheld calls is difficult to satisfy. Currently available traditional antennas have poor low-frequency head-and-hand performance. Therefore, this invention is necessary to propose a high-performance terminal antenna and a mobile terminal using this antenna. Utility Model Content

Detailed Implementation

[0020] The high-performance terminal antenna and mobile terminal 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 figures may emphasize different aspects and sometimes use different proportions.

[0021] Currently, mobile communication operators have standards for mobile terminals, with defined ranges for free space and simulated handheld calls. In many project debugging processes, the performance of free space is easy to meet, but the performance of simulated handheld calls is difficult to meet. Existing traditional antennas have poor low-frequency head-and-hand performance. In view of this, it is indeed necessary to propose a high-performance terminal antenna and a mobile terminal using the terminal antenna.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a high-performance terminal antenna, which includes interconnected radiating antenna units 100 and brackets 80. The radiating antenna unit 100 includes a first radiating antenna 10, a second radiating antenna 20, a third radiating antenna 30, a fourth radiating antenna 40, a grounding point 11, and a feed point 12. The first radiating antenna 10 is connected to the second radiating antenna 20 and the third radiating antenna 30, and the first radiating antenna 10 is connected to the fourth radiating antenna 40. A first gap 50 is formed between the first radiating antenna 10 and the third radiating antenna 30, a second gap 60 is formed between the first radiating antenna 10 and the fourth radiating antenna 40, and a third gap 70 is formed between the third radiating antenna 30 and the fourth radiating antenna.

[0023] This design simplifies the overall antenna structure and reduces the influence of human heads and hands, effectively improving the head and hand radiation performance of the smart terminal. In practical applications, the performance of this high-performance terminal antenna can be further optimized by adjusting the gaps between the radiating antennas, as well as their shape and length. For example, by adjusting the widths of the first gap 50, the second gap 60, and the third gap 70, the resonant frequency and bandwidth of the antenna can be changed to adapt to different communication frequency band requirements. Simultaneously, the shape and length of the first radiating antenna 10, the second radiating antenna 20, the third radiating antenna 30, and the fourth radiating antenna 40 can also be fine-tuned to further improve the antenna's radiation efficiency and directivity.

[0024] In mobile terminals, this high-performance terminal antenna can be installed inside mobile phones or other smart terminal devices, and connected to the device's circuit board or other structural components via a bracket 80. In practical use, when the antenna receives signals from a base station or other communication equipment, the signals are received and transmitted through the radiating antenna element 100, thereby realizing the communication function. Simultaneously, due to its simplified structure and reduced interference from human heads and hands, this high-performance terminal antenna can effectively improve the communication performance and user experience of mobile terminals.

[0025] Furthermore, the first radiating antenna 10 is rectangular in shape, with one end connected to the second radiating antenna 20 and the other end connected to the fourth radiating antenna 40. The feed point 12 is electrically connected to the second radiating antenna 20, and the ground point 11 is electrically connected to the fourth radiating antenna 40. This configuration ensures effective signal transmission and reception. In practical applications, the feed point 12 serves as the signal input terminal, electrically connected to the second radiating antenna 20 to transmit the received signal. Simultaneously, the ground point 11 serves as the signal return path, electrically connected to the fourth radiating antenna 40 to ensure signal stability and integrity. This electrical connection method not only simplifies the antenna structure but also improves its performance.

[0026] Preferably, one end of the second radiating antenna 20 is connected to the first radiating antenna 10, and one end of the second radiating antenna 20 is a free end, with the feed point 12 electrically connected to the free end of the second radiating antenna 20. The third radiating antenna is L-shaped, and one end of the third radiating antenna is connected to one side segment of the first radiating antenna. This arrangement further increases the flexibility and adaptability of the antenna. The L-shaped design of the third radiating antenna allows the antenna to better adapt to different spatial environments and angles when receiving and transmitting signals, thereby improving the stability and quality of communication. Simultaneously, the third radiating antenna is located above the fourth radiating antenna and is longer than the fourth radiating antenna; this layout helps optimize the antenna's radiation direction and efficiency, reducing signal interference and loss. In practical applications, the performance of this high-performance terminal antenna can be further optimized by adjusting parameters such as the size, shape, and length of the gaps between the radiating antennas. For example, by adjusting the widths of the first gap 50, the second gap 60, and the third gap 70, the resonant frequency and bandwidth of the antenna can be changed to adapt to different communication frequency band requirements. Meanwhile, the shape and length of each radiating antenna can be fine-tuned to further improve the antenna's radiation efficiency and directivity, thereby enhancing the stability and quality of communication.

[0027] Furthermore, the third radiating antenna is located above the fourth radiating antenna, and the length of the third radiating antenna is greater than that of the fourth radiating antenna. The fourth radiating antenna is connected to one end of the first radiating antenna and is L-shaped. This configuration further optimizes the antenna's radiation efficiency and directivity. In practical applications, the L-shaped fourth radiating antenna design helps the antenna better adapt to different spatial environments and angles when receiving and transmitting signals, thereby improving communication stability and quality. Simultaneously, the connection method between the fourth and first radiating antennas, as well as the size of the gap between them, can be fine-tuned to adapt to different communication frequency band requirements, further improving antenna performance. This refined design and adjustment enable the high-performance terminal antenna of this invention to have excellent communication performance and user experience in practical applications.

[0028] Specifically, the width of the second gap formed between the first and fourth radiating antennas is greater than the width of the third gap, and the width of the second gap is greater than the width of the first gap. The second gap and the third gap are connected, and the first gap and the third gap are also interconnected. This configuration further optimizes the electromagnetic performance of the antenna. In practical applications, by adjusting the width and connectivity of these gaps, the resonant mode, frequency response, and bandwidth characteristics of the antenna can be altered, thereby better adapting it to different communication environments and frequency band requirements. For example, increasing the width of the second gap can enhance the antenna's radiation efficiency in a specific frequency band, while maintaining the connectivity of the first and third gaps helps improve the antenna's matching performance and signal stability. This fine-tuning and optimization enables the high-performance terminal antenna of this invention to perform excellently in various communication scenarios, providing users with a stable and efficient communication experience.

[0029] In summary, this utility model provides a high-performance terminal antenna and a mobile terminal. The high-performance terminal antenna includes interconnected radiating antenna units 100 and a support 80. Each radiating antenna unit includes a first radiating antenna 10, a second radiating antenna 20, a third radiating antenna 30, a fourth radiating antenna 40, a grounding point 11, and a feed point 12. The first radiating antenna 10 is connected to the second radiating antenna 20 and the third radiating antenna 30, and the first radiating antenna 10 is connected to the fourth radiating antenna 40. A first gap 50 is formed between the first radiating antenna 10 and the third radiating antenna 30, a second gap 60 is formed between the first radiating antenna 10 and the fourth radiating antenna 40, and a third gap 70 is formed between the third radiating antenna 30 and the fourth radiating antenna.
