DETAILED DESCRIPTION

[0020] The high-performance terminal antenna and the mobile terminal device according to the present application will be further described below in conjunction with the drawings and specific embodiments. It should be noted that the drawings are all very simplified and use non-precise proportions, and are only used to facilitate and clarify the purpose of assisting the description of the embodiments of the present application. In addition, the structures shown in the drawings are often part of the actual structure. In particular, the emphasis of each drawing is different, and sometimes different proportions are used.

[0021] The present application provides a kind of high-performance terminal antenna and the mobile terminal device of application this antenna, such as the mobile terminal device of our daily used mobile phone, tablet computer and laptop etc. can be applied.

[0022] The high-performance terminal antenna of the present application comprises a first metal frame, a second metal frame 20 and a third metal frame, which are sequentially coupled to form a metal ring-shaped frame. A first gap 40 is provided between the first metal frame and the second metal frame 20, a second gap 50 is provided between the first metal frame and the third metal frame, and a third gap 60 is provided between the third metal frame and the second metal frame 20.

[0023] In other words, the metal ring-shaped frame is provided with a first gap 40, a second gap 50 and a third gap 60 at different positions. The metal frame is slit on the antenna mainly to solve the problem of antenna signal transmission. Since the metal frame will block the model transmission of the antenna, the slit on the metal frame can make the antenna signal pass smoothly, ensuring the communication quality. Specifically, the effects of the metal frame slit include improving the antenna efficiency-the slit design of the metal frame can make the antenna signal radiate and receive better, thereby improving the efficiency of the antenna. This is because the slit allows electromagnetic waves to pass through the metal frame, reducing the situation of signal being blocked. Enhance signal stability-By slitting the metal frame, the stable transmission of wireless signals can be ensured, especially under high-frequency communication technologies such as 5G, this design can ensure the stability and continuity of the signal. Improve user experience-the slit design not only improves the communication quality, but also improves the user's communication experience, reducing the problem of intermittent calls or data transmission interruption caused by poor signal. In addition, some researches also propose that by distributing the coupling of the metal frame, the high Q value influence of the closed metal boundary on the antenna system can be reduced, and the low frequency resonance of the antenna can be generated by using the frame resonance, thereby reducing the size of the internal antenna design.
