Embodiment Construction

[0012] The technical solution of the present invention is described as follows in conjunction with the accompanying drawings:

[0013] like figure 1 As shown, a mobile terminal includes a metal frame 2, a metal bracket 1 for installing a display screen, and an antenna radiator 7. The metal bracket 1 is installed in the metal frame 2 and its left and right sides are aligned with the The corresponding sides of the metal frame 2 cooperate, the top edge of the metal frame 1 and the corresponding side of the metal frame 2 form a first metal ring 3, the bottom edge of the metal frame 1 and the corresponding side of the metal frame 2 A second metal ring 4 is formed, and the first and second metal rings ( 3 , 4 ) are located in the projection area of ​​the antenna radiator 7 . The first metal ring extends inwardly from a grounding piece 51 and a grounding piece 52; the second metal ring extends inwardly from a grounding piece 51 and a grounding piece 52, and the grounding pieces (51,...

Abstract

The invention brings forward a mobile terminal comprising a metal frame, a metal support used for installation of a display screen and an antenna radiation body. The metal support is installed in the metal frame, and at least two edges of the metal support are matched with the corresponding edges of the metal frame. A metal ring is formed by the non-matching edges on the metal support and the edges, which are corresponding to the non-matching edges on the metal support, of the metal frame together. The metal ring is arranged in the projection area of the antenna radiation body. The mobile terminal is characterized in that the metal ring is provided with a grounding device which is connected with the reference ground of the mobile terminal. The objective of the mobile terminal is to solve a problem of strong coupling between the metal ring structure and the antenna radiation body in the mobile terminal so that antenna radiation efficiency is guaranteed.

Description

technical field [0001] The invention relates to a mobile terminal Background technique [0002] For a mobile terminal with a metal frame, the non-matching part of the metal frame and the metal bracket placed inside it for installing the display screen will form a ring structure, which is generally called a "metal ring". The radiation (especially high-frequency radiation) of traditional monopole and IFA antennas will form a strong coupling with the metal ring, resulting in a significant drop in the efficiency of antenna radiation into space. In this regard, the existing improvement plan is to disconnect the metal ring to destroy the ring structure. Although this eliminates the influence of strong coupling on antenna radiation to a certain extent, it also brings sensitivity problems when people's hands or heads touch the fracture of the metal ring. It not only increases the difficulty and cost of production, processing, stability, etc., but also has a certain impact on the a...
