[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] 5G antennas and WiFi antennas are both important components of 5G mobile communication. 5G mobile communication features ultra-high data transmission rates, ultra-low latency, ultra-high bandwidth, ultra-high capacity, multi-antenna technology, and backward compatibility.

[0028] With this configuration, the high-efficiency full-band antenna of this invention can not only simplify the overall structural design of the antenna, but also achieve miniaturization, high radiation efficiency, and broaden the overall radiation frequency band of the antenna.

[0029] In practical implementation, a substrate 10 is first prepared. This substrate 10 is made of FR4 material, which has stable electrical performance and good mechanical strength. Then, a first radiating unit 21, a second radiating unit 22, and a third radiating unit 23 are sequentially arranged on the front side of the substrate 10. The radiating units are connected by microstrip lines to ensure smooth signal transmission. The first radiating unit 21 is composed of a first stub antenna 210, a second stub antenna 211, and a third stub antenna 212 connected sequentially. The third stub antenna 212 is electrically connected to the feed point 40 and is used for receiving and transmitting signals. The second radiating unit 22 is composed of a fourth stub antenna 220 and a fifth stub antenna 221 connected to each other. The fourth stub antenna 220 is electrically connected to the ground point 41 and is used to provide a return path for the signal.

[0030] Specifically, the first radiating element 21 includes a first stub antenna 210, a second stub antenna 211, and a third stub antenna 212 connected in sequence, with the third stub antenna 212 electrically connected to the feed point 40. Further, the second radiating element 22 includes a fourth stub antenna 220 and a fifth stub antenna 221 connected to each other, with the fourth stub antenna 220 electrically connected to the ground point 41. This configuration further enhances the antenna's stability and signal transmission efficiency. In a specific embodiment, the first stub antenna 210, second stub antenna 211, third stub antenna 212, fourth stub antenna 220, fifth stub antenna 221, and sixth stub antenna 320 are all made of copper, possessing good conductivity and mechanical strength. Furthermore, the length and width of each stub antenna are precisely calculated to ensure good matching and radiation performance of the antenna within the required frequency band.

[0031] Preferably, the first stub antenna 210 is M-shaped, the second stub antenna 211 is U-shaped, and the third stub antenna 212 is connected to the second stub antenna and extends from the U-shaped opening of the second stub antenna 211. The fourth stub antenna 220 is rectangular and is coupled to the third stub antenna 212. This configuration further enhances the antenna's coupling effect and frequency band coverage. In practical applications, the M-shaped and U-shaped designs of the first and second stub antennas 210 and 211, and the structure of the third stub antenna 212 extending from the U-shaped opening of the second stub antenna 211, give the antenna good radiation performance in the low-frequency band. Simultaneously, the rectangular design of the fourth stub antenna 220 and its coupling with the third stub antenna 212 provide excellent radiation efficiency and stability in the high-frequency band, especially in the dual-band WiFi. This design not only meets various communication needs but also improves communication stability and reliability. Furthermore, during the manufacturing process of this high-efficiency full-band antenna, the length and width of each stub antenna are rigorously calculated and precisely processed to ensure good matching and radiation performance within the required frequency band. Simultaneously, the stub antennas made of copper possess excellent conductivity and mechanical strength, further improving the antenna's stability and service life.

[0032] Applying this high-efficiency full-band antenna to mobile terminals can significantly improve their communication performance. Using this antenna not only enables high-speed data transmission but also enhances signal reception sensitivity and stability, providing users with a better communication experience.

Further, the first stub antenna 210 and the fourth stub antenna 220 are coupled and configured to control the frequency band as 690-960 / 1710-2170 / 2496-2690 / 3300-4200 / 5000-6000MHz, i.e., 690MHz-960MHz or 1710MHz-2170MHz or 2496MHz-2690MHz or 3300MHz-4200MHz or 5000MHz-6000 MHz. The second stub antenna 211 and the sixth stub antenna 320 are coupled and configured to control the dual-band WiFi signal, with a frequency range of 2400-2500 / 5100-5900MHz, i.e., 2400MHz-2500MHz or 5100MHz-5900MHz. This configuration further optimizes the antenna's impedance matching and frequency band coverage performance. In a specific embodiment, the grounding component effectively adjusts the antenna's impedance, ensuring good matching across different frequency bands, thereby improving the antenna's radiation efficiency and signal transmission quality. Simultaneously, the M-shaped design of the sixth radiating element 33 enhances the antenna's radiation performance at higher frequencies, resulting in higher gain and more stable signal transmission within the dual-band WiFi signal. Furthermore, the high-efficiency full-band antenna of this invention exhibits high structural flexibility and adjustability. By adjusting the length, width, and coupling method of each stub antenna, precise control of the antenna's frequency band coverage can be achieved, thus meeting the communication needs of different application scenarios. This flexibility and adjustability make the antenna of this invention widely applicable in various communication devices and systems.
