Description

Technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a mobile terminal and an antenna of the mobile terminal. Background technique [0002] Because of the beautiful metal texture, mobile phones with metal frames are more and more sought after by mobile phone companies. However, the metal frame around the antenna significantly inhibits the antenna radiation, making the antenna design difficulty of the corresponding mobile phone significantly increased. [0003] For 4G LTE (Long Term Evolution, the fourth-generation mobile antenna standard) mobile phone LTE Diversity (diversity) antenna, GPS (Global Positioning System, global positioning system) antenna, and BT (Blue Tooth, Bluetooth) & WLAN (Wireless Local Area Network, wireless local area network) antenna, there are roughly the following two solutions in related technologies: [0004] Solution one is the mainstream solution currently on the market, using the traditional an...

AI Technical Summary

Problems solved by technology

[0006] The disadvantages of solution 1 in the above-mentioned related technologies are: the traditional antenna design and production process are still used, and there is no cost saving; more importantly, the metal frame cannot be well integrated with the antenna. This has a considerable negative impact on the radio frequency performance of the antenna, resulting in poor radio frequency performance of the antenna

[0007] The shortcomings of the second solution in the above-mentioned related technologies are: it is difficult to debug the antenna. This is because the second solution uses the segmented metal frame to directly feed the antenna. When the size of the metal frame is not suitable for antenna resonance and radiation, it is impossible to manually Debugging (because the increase and shortening of the metal frame size is difficult to change manually), and if the prototype is modified, the cycle and cost are unavoidable problems
