Embodiment Construction

[0038] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0039] The present application provides an antenna system, which is applied to a mobile terminal to realize information transmission between the mobile terminal and a base station. This application takes a mobile phone as an example to describe the antenna system provided by this application. However, it should be noted that the mobile terminal is not limited to a mobile phone, but may also be a tablet computer, a notebook, and other handheld devices.

[0040] like figure 1 As shown, the mobile terminal 1 generally includes a display screen 11 and a rear case 12 opposite to the display screen 11 and arranged at intervals, and a metal frame 13 extending along the outer contour of the rear case 12 is arranged between the display screen 11 and the rear case 12 As well as a circuit board, a feed point is provided on the circuit b...

Abstract

The invention relates to an antenna system and a mobile terminal. The mobile terminal comprises a display screen, a rear shell opposite to the display screen, a metal frame which stretches along the outer contour of the rear shell and is clamped between the display screen and the rear shell, and a circuit board. The antenna system comprises at least one antenna unit. Each antenna unit comprises a first slot arranged on the metal frame and a second slot connected with the first slot. The first slot stretches along a circumference direction of the metal frame, thereby forming a strip-shaped hollow on the metal frame. The second slot stretches from the middle part of the first slot along the direction of the rear shell to the edge of the metal frame, thereby dividing the metal frame on the edge of the first slot into a first branch and a second branch. The first branch and the second branch are electrically connected with a feeding point, thereby forming a first radiator and a second radiator of the antenna unit. According to the scheme, an interval is reserved between the slots of the antenna system and the display screen, so the bad influence of the display screen on the antenna system is reduced, and the performance of the antenna system is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to an antenna system and a mobile terminal. Background technique [0002] With the advancement of technology, on the one hand, mobile terminals with large-size display screens are widely adopted by manufacturers; on the other hand, mobile terminals with metal frames are very popular among consumers due to their tough appearance and great texture. [0003] In the antenna design of a metal-frame mobile terminal with a large-size display screen, it is usually chosen to open a through gap on the metal frame, so that the metal frame with the gap becomes a part of the antenna and leaks signals from the gap to the outside. However, most of the display screens are made of ITO (Indium tin oxide, transparent conductive film) material, which has characteristics such as high impedance and high loss. Not so good. [0004] Therefore, it is necessary to propose an antenna design s...
