Embodiment Construction

[0053] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0054] Such as Figure 1-3 As shown, the embodiment of the present invention provides an antenna system, which can be used in a mobile terminal, such as a mobile phone. The antenna system includes a metal case 10, a main board 20, an antenna unit 30 and a tuning switch (not shown in the figure). The metal casing 10 comprises a top frame 11, a bottom frame (not shown in the figure) and a middle back shell 13 which is respectively provided with a break 14 with the top frame 11 and the bottom frame, and the top frame 11 or the bottom frame are connected to each other through a connecting rib 15. The middle back shell 13 is connected, such as figure 1 As shown, the metal shell 10 is provided with two broken seams 14, and the two broken seams 14 divide the metal shell 10 into a top frame 11, a middle back shell 13 and a bottom fr...

Abstract

The invention relates to the technical field of communication, in particular to an antenna system and a mobile terminal. The antenna system comprises a metal shell, a mainboard, an antenna element and a tuning switch, wherein the mainboard is provided with a feeding point, a first ground point and a second ground point; the feeding point is connected with the antenna element; the first ground point is connected with a top border; the second ground point is connected with the top border through the tuning switch; and at least one part of the antenna element is opposite to the top border and the at least one part of the antenna element and the top border are arranged at an interval, so that the top border is coupled to the antenna element to form a first antenna, a second antenna and a third antenna. The medium-frequency radiation efficiency and the high-frequency radiation efficiency in the antenna system can be improved; and the medium-frequency bandwidth and the high-frequency bandwidth of the antenna system can be tuned to be increased through selection of different states of the tuning switch.

Description

technical field [0001] The present invention relates to the technical field of antenna systems, in particular to an antenna system and communication equipment. Background technique [0002] At present, communication devices with metal shells, such as mobile phones, have become the mainstream structure of mobile phones of various brands. When designing the antenna of the mobile phone, there are usually broken seams on the shell. Generally, the broken seams run through the width of the mobile phone. The shell is divided into three parts: two frames and a back shell, that is, the shell has a three-section structure; the feed point on the main board is directly connected to the frame, so that the frame forms a radiator. However, in this antenna system, only the frame is used as a radiator, and the bandwidth of the intermediate frequency and high frequency of the formed antenna system is relatively narrow, and the radiation efficiency is relatively low.
