[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] To reduce the harm to human health and safety caused by electromagnetic radiation from mobile phones, most countries and regions have established mandatory safety standards for the SAR (Specific Absorption Rate) of mobile phones. However, different regions have different requirements for SAR values. Currently available solutions are relatively more complex than traditional antenna designs, and the concentrated current in traditional antennas leads to SAR exceeding the standard.

[0004] In view of this, it is indeed necessary to propose a terminal antenna that reduces SAR values ​​and a mobile terminal device that uses the antenna. Utility Model Content

[0021] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates the terminal antenna and mobile terminal device for reducing SAR values ​​proposed in this utility model. It should be noted that the drawings are all in a very simplified form and use non-precise scales, 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 scales.

[0022] With the continuous development of 5G base station construction, the frequency bands supported by communication terminals are constantly expanding. Today, 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 the phone. However, the space in a mobile phone is limited, and the bandwidth of the antenna is also limited by space, resulting in a limited frequency band coverage and making it difficult to achieve wide-band radiation. To reduce the harm to human health and safety caused by electromagnetic radiation from mobile phones, most countries and regions have established mandatory safety standards for the SAR value of mobile phones, and different regions have different requirements for SAR values. Currently, existing solutions are relatively complex compared to traditional antenna designs, and the concentrated current in traditional antennas leads to excessive SAR. Therefore, a new type of antenna is needed to solve the problem of high radiation from the head and hands.

[0023] This invention provides a terminal antenna that reduces SAR values. This terminal antenna can be used in mobile terminal devices, such as smartphones, tablets, and laptops. In other words, this terminal antenna that reduces SAR values ​​can be easily integrated into various mobile terminal devices, such as smartphones, tablets, and laptops, to meet the needs of different users.

[0024] Specifically, the terminal antenna for reducing SAR values ​​includes a ground plane 10, a feed assembly 20, and a radiating assembly. The radiating assembly is electrically connected to the feed assembly 20. The radiating assembly includes a first radiating element 30, a second radiating element 40, and a third radiating element 50. The first radiating element 30 is coupled to the second radiating element 40 and the third radiating element 50. The second radiating element 40 is coupled to the third radiating element 50 and surrounds the second radiating element 40.

[0025] This configuration, through the coupling connection of the first radiating element 30, the second radiating element 40, and the third radiating element 50, especially the structure where the first radiating element 30 and the third radiating element 50 are coupled together and surround the second radiating element 40, effectively disperses the electromagnetic radiation generated by the antenna during operation, thereby reducing the SAR value. Furthermore, this surrounding structure also helps improve the antenna's bandwidth radiation performance, enabling the antenna to operate efficiently over a wider frequency band. This invention's SAR-reducing terminal antenna not only simplifies the design of traditional antennas and reduces production costs, but also effectively reduces the SAR value.

[0026] Furthermore, the first radiating element 30, the second radiating element 40, and the third radiating element 50 are all configured symmetrically. This configuration further enhances the antenna's performance stability, resulting in a more uniform radiation characteristic in different directions.

[0027] Specifically, the first radiating element 30 includes a first end 31 and a second end 32. The first end 31 is coupled to one side of the third radiating element 50, and the second end 32 is coupled to the other side of the third radiating element 50. This configuration further enhances the coupling effect between the first radiating element 30 and the third radiating element 50, thereby reducing the antenna SAR value and effectively improving the overall performance of the antenna. Furthermore, this coupling connection method helps optimize the antenna's radiation pattern, giving the antenna stronger radiation capability in specific directions, thus meeting different communication needs.

[0028] Furthermore, the first radiating element 30 includes a first end 31 and a second end 32, both of which are arranged in a comb-like configuration. This comb-like configuration of the first and second ends 31 and the third radiating element 50, coupled with them, not only simplifies the antenna structure but also helps improve its operating efficiency. The two ends of the third radiating element 50 are respectively arranged in a comb-like configuration, coupled with the first end 31 and the second end 32. This configuration further enhances the coupling tightness between the first radiating element 30 and the third radiating element 50, thereby improving the overall performance of the antenna while ensuring a reduction in SAR values. In addition, this comb-like coupling structure also helps reduce the size of the antenna, making it more adaptable to the miniaturization trend of mobile terminal devices.

[0029] Furthermore, the first radiating element 30 and the third radiating element 50 are coupled together to form a rectangular ring, and the second radiating element 40 is located within this rectangular ring. The second radiating element 40 is symmetrically placed within the rectangular ring and coupled to the first radiating element 30 and the third radiating element 50. This configuration further improves the performance stability of the antenna, enabling it to maintain good operating conditions in different environments.

[0030] Preferably, the first radiating element 30 and the third radiating element 50 are coupled together to form a rectangular ring, and the second radiating element 40 is located within this rectangular ring. This rectangular ring structure not only enhances the structural stability of the antenna but also helps to optimize the antenna's radiation characteristics, resulting in a more uniform radiation capability across a wider frequency band.

[0031] The second radiating element 40 is symmetrically positioned within the rectangular ring and coupled to the first radiating element 30 and the third radiating element 50. This arrangement further enhances the uniformity of the electromagnetic field distribution within the antenna, thereby further reducing the SAR value. Simultaneously, this symmetrical coupling structure also helps improve the antenna's polarization purity, resulting in higher efficiency in both signal reception and transmission.

[0032] Furthermore, the axes of symmetry of the first radiating element 30, the second radiating element 40, and the third radiating element 50 are all located on the same straight line. This symmetrical arrangement not only simplifies the antenna structure but also helps improve the antenna's directivity, giving it stronger radiation capability in a specific direction to meet different communication needs. The feeding assembly 20 is configured with coaxial feeding. This coaxial feeding method ensures a stable electrical connection between the antenna and the mobile terminal device, and also helps improve the antenna's signal transmission quality. The coaxial feeding method has advantages such as simple structure and stable performance, effectively ensuring the normal operation of the antenna. In addition, the coaxial feeding method also helps reduce the size and weight of the antenna, making it more suitable for the trend of lightweight mobile terminal devices.

[0033] In summary, this invention provides a terminal antenna and mobile terminal device that reduce SAR values. The SAR-reducing terminal antenna includes a ground plane 10, a feed assembly 20, and a radiating assembly, with the radiating assembly electrically connected to the feed assembly 20. The radiating assembly includes a first radiating element 30, a second radiating element 40, and a third radiating element 50. The first radiating element 30 is coupled to the second radiating element 40 and the third radiating element 50, and the second radiating element 40 is coupled to the third radiating element 50. The first radiating element 30 surrounds the second radiating element 40 after being coupled to the third radiating element 50. This SAR-reducing terminal antenna not only simplifies the design of traditional antennas and reduces production costs but also effectively reduces SAR values.
