[0019] Among them, each figure mark is as follows:

[0021] The utility model discloses high radiating efficiency's antenna makes further detailed explanation below combining with the drawings and specific embodiment. It is explained that, the drawings all adopt very simplified form and all use non-precise scale, only use to facilitate, clear and brightly assist the purpose of the explanation of the utility model embodiment. Besides, the structure that the drawing shows is often a part of actual structure. Especially, the emphasis of each drawing needs to show is different, sometimes uses different scale.

[0022] At present, the popularity of 5G mobile phone makes the number of antennas increase, and one or two antenna branches will be added near the battery compartment. The increased antenna form generally increases the parasitic in single stage, but the coupling area of the antenna body and the parasitic is relatively small, so the overall efficiency of the antenna is relatively poor. The metal frame mobile phone on the market generally adopts a full metal frame breakpoint form, which makes a breakpoint at a suitable frame position to intercept a section to make it an antenna. Limited by the frame, the antenna layout has determined the basic antenna performance. A separate section of metal frame is needed to make a radiator as an antenna at the bottom and the side of the battery compartment. Such manufacturing process is relatively complex.

[0023] The utility model provides a kind of high radiation efficiency's antenna, which can be applied in mobile terminal equipment, the high radiation efficiency's antenna includes feed part 30, ground part 40, radiation body part 10 and parasitic radiation part 20, one end of the radiation body part 10 is electrically connected with the feed part 30 and the ground part 40, the other end of the radiation body part 10 is free end part;The parasitic radiation part 20 is coupled with the radiation body part 10, one end of the parasitic radiation part 20 is crossed parallel coupled with the free end part of the radiation body part 10;The feed part 30 and the ground part 40 are both arranged in one side of the radiation body part 10.

[0024] So set, the high radiation efficiency's antenna of the utility model is optimized antenna structure, and the parasitic radiation part 20 of special design is combined with the radiation body part 10, so that antenna can effectively radiate electromagnetic wave in limited space, not only solve the problem that the overall efficiency of antenna is poor in prior art, and bandwidth radiation is limited, but also effectively improve the overall radiation efficiency of antenna.

[0025] Further, the radiation body part 10 is U-shaped, the parasitic radiation part 20 is U-shaped, and the opening of the radiation body part 10 is arranged opposite to the opening of the parasitic radiation part 20. The radiation body part 10 and the parasitic radiation part 20 are both arranged on one side of the mobile terminal. This relative arrangement design makes the coupling effect between the two more significant, further enhancing the radiation capability of the antenna. At the same time, the U-shaped design also enables the antenna to occupy a smaller space while more effectively capturing and radiating electromagnetic waves, improving the adaptability of the antenna on the mobile terminal device. In specific implementation, the radiation performance of the antenna can be further optimized by adjusting the size, shape and relative position of the radiation body part 10 and the parasitic radiation part 20. For example, the size of the radiation body part 10 and the parasitic radiation part 20 can be appropriately increased, or their opening sizes can be adjusted to obtain better radiation efficiency and bandwidth performance. In addition, to further improve the stability and durability of the antenna, a reinforcing structure can be used at the connection between the radiation body part 10 and the parasitic radiation part 20, such as adding a connecting piece or reinforcing material, to ensure that the antenna can maintain good working condition during long-term use.

[0026] The radiation body part 10 comprises a first radiation branch, a second radiation branch and a third radiation branch, the first radiation branch and the second radiation branch are perpendicular to each other, and the second radiation branch and the third radiation branch are perpendicular to each other. One end of the first radiation branch is electrically connected with the feeding part 30, and the other end is connected with one end of the second radiation branch; the other end of the second radiation branch is connected with one end of the third radiation branch, and the other end of the third radiation branch forms a free end. Such design makes the radiation body part 10 form a three-dimensional structure, further enhancing the radiation effect of the antenna. Meanwhile, the perpendicular arrangement of the first radiation branch, the second radiation branch and the third radiation branch enables the antenna to better radiate electromagnetic waves in three-dimensional space, improving the overall radiation efficiency of the antenna.

[0027] The parasitic radiation part 20 comprises a first parasitic branch, a second parasitic branch and a third parasitic branch, the first parasitic branch and the second parasitic branch are perpendicular to each other, and the second parasitic branch and the third parasitic branch are perpendicular to each other. Such design of the first parasitic branch, the second parasitic branch and the third parasitic branch makes the coupling between the parasitic radiation part 20 and the radiation body part 10 more close, further enhancing the radiation effect of the antenna. Meanwhile, such perpendicular design also enables the antenna to be more flexibly arranged in limited space, optimizing the overall structure of the antenna. Through fine design and adjustment, the antenna of the utility model ensures high radiation efficiency while maintaining good stability and reliability, providing high-quality communication performance for mobile terminal equipment.

[0028] The end parts of the radiation body part 10 and the parasitic radiation part 20 coupled with each other are parallel and cross each other, and the free end part of the radiation body part 10 is arranged apart from the parasitic radiation part 20. One end of the parasitic radiation part 20 coupled with the free end part of the radiation body part 10 is located below the radiation body part 10, and the free end of the radiation body part 10 is located above the parasitic radiation part 20. The opening formed by the radiation body part 10 is oppositely arranged with the opening formed by the parasitic radiation part 20 and penetrates each other. Preferably, the coupling distance between the radiation body part 10 and the parasitic radiation part 20 ranges from 0.5mm to 1mm. Such distance ensures effective electromagnetic coupling between the radiation body part 10 and the parasitic radiation part 20, while avoiding physical contact or interference due to being too close, ensuring the performance and stability of the antenna as a whole. In addition, the selection of the coupling distance also takes into account the precision requirements of the manufacturing process, so that the antenna can maintain a high yield rate during production.

[0029] The radiation body part 10 and the parasitic radiation part 20 are partially and cross-parallel arranged, so that the coupling area between the two is effectively increased, thereby enhancing the radiation efficiency of the whole antenna. This design not only optimizes the radiation characteristics of the antenna, but also enables the antenna to effectively realize a wider signal coverage range while maintaining a compact volume layout. In addition, by accurately controlling the coupling distance between the radiation body part 10 and the parasitic radiation part 20, the performance stability of the antenna is further improved, and signal fluctuations caused by environmental factors are reduced. In practical applications, this high-radiation-efficiency antenna can significantly improve the communication quality of mobile terminal devices and provide users with more stable and smooth communication experience.

[0030] In summary, the utility model discloses a kind of high-radiation-efficiency antennas, applied on mobile terminal, the high-radiation-efficiency antenna includes feed part 30, ground part 40, radiation body part 10 and parasitic radiation part 20, one end of the radiation body part 10 is electrically connected with the feed part 30 and the ground part 40, and the other end of the radiation body part 10 is free end part;The parasitic radiation part 20 is coupled with the radiation body part 10, and one end of the parasitic radiation part 20 is cross-parallel coupled with the free end part of the radiation body part 10;The feed part 30 and the ground part 40 are arranged on one side of the radiation body part 10.The high-radiation-efficiency antenna of the utility model optimizes antenna structure, adopts specially designed parasitic radiation part 20 and radiation body part 10, so that antenna can effectively radiate electromagnetic wave in limited space, not only solve the problem that the whole efficiency of antenna is poor in prior art, and bandwidth radiation is limited, but also effectively improve the radiation efficiency of whole antenna.
