Mobile phone antenna

Abstract

An embodiment of the invention relates to the technical field of communication, and discloses a mobile phone antenna. The mobile phone antenna comprises a metal frame and a mainboard arranged in the metal frame; breakpoints are arranged on the metal frame; the breakpoints are used for dividing the metal frame into a plurality of sub-metal sections which are separated mutually; the plurality of thesub-metal sections at least include a first sub-metal section which forms a clearance area of a diversity antenna together with the mainboard, a second sub-metal section which forms a clearance areaof a three-in-one antenna together with the mainboard, and a third sub-metal section located between the first sub-metal section and the second sub-metal section and used for arranging a metal part ofa mobile phone; the first sub-metal section is a radiation body of the diversity antenna; and the second sub-metal section is a radiation body of the three-in-one antenna. According to the mobile phone antenna provided by the invention, while the performance of the antenna is improved and the space of the mainboard is saved, the cost of the mobile phone is reduced.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of communication, and in particular to a mobile phone antenna. Background technique [0002] The design of today's smartphones pursues the ultimate screen-to-body ratio, such as the popular notch screen, beauty-pointed screen, and hidden proactive design, which can be said to have pushed the screen-to-body ratio of mobile devices to a new height and are widely recognized by users. Welcome and love. But the problem that comes with it is that the antenna design environment is compressed by the high screen ratio, and the metal parts on the top of the mobile phone are closer to the antenna, which reduces the headroom area of ​​the antenna, resulting in a relative decline in antenna performance. In the prior art, the metal frame design structure is usually adopted. On the one hand, the metal frame has the advantages of good hand feeling and ultra-thin body. On the other hand, using the ...

AI Technical Summary

Problems solved by technology

[0003] The inventors have found that there are at least the following problems in the prior art: the antennas in the prior art are concentrated in the middle part of the metal frame. Since the middle part is a dense area of ​​metal parts of the mobile phone, the environment of the antenna is harsh (that is, the antenna clearance area is small), which leads to The performance of the antenna is not high; the metal frame is usually used as the radiator of multiple antennas. Since different antennas need a certain degree of isolation from each other, multiple antennas will take up a lot of motherboard space, which will increase the cost of the mobile phone
