Embodiment Construction

[0042] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0043] like figure 1 As shown, the embodiment of the present invention provides an antenna system, which can be applied to mobile terminals such as mobile phones and tablet computers. Usually, mobile terminals such as mobile phones and tablet computers have a rectangular structure, which has a length direction and a width direction, and the length direction is figure 1 The Y direction shown in the width direction is figure 1 X direction shown in .

[0044] The antenna system includes a metal case, a circuit board 10 , a first antenna unit 12 and a second antenna unit 14 . The circuit board 10 is located in a metal casing, and the circuit board 10 includes a system ground and a radio frequency feed. The metal shell is provided with a gap zone to divide the metal shell into a radiation frame 16 and a grounded back shell 18. ...

Abstract

The invention relates to an antenna system and a mobile terminal; the antenna system comprises a metal housing, a circuit board located in the metal housing, the first antenna unit and the second antenna unit; the metal housing comprises a radiation frame and a grounding back shell; the first gap and the second gap are respectively formed between two ends of the radiation frame and the grounding back shell; the radiation frame is provided with a grounding point connected with a system of the circuit board and a feed point connected with a radio frequency feed source of the circuit board; the grounding point is closer to the second gap when compared with the first gap; the feed point is closer to the first gap when compared with the second gap; the first and second antenna units are respectively connected with the system; the first and second antenna units and the radiation frame are respectively arranged at an interval, and coupled to the radiation frame; the first antenna unit is located between the grounding point and the feed point; the second antenna unit is located between the feed point and the first gap. The antenna system can form a plurality of work frequency ranges, thusrealizing the polyfunctionality.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an antenna system and a mobile terminal. Background technique [0002] With the rapid development of communications, mobile terminals have become an indispensable tool in people's lives. In order to obtain better appearance design and hand-held feeling, metal shells are increasingly used in the design of mobile terminals. However, due to the use of metal shells and the control of the length and thickness of mobile terminals by terminal manufacturers, the space of the antenna system will be occupied to a certain extent, which puts forward higher requirements for the design of the antenna system. [0003] At present, antennas with multiple functions usually exist in mobile terminals, such as diversity antennas, main antennas, WIFI antennas, and GPS antennas, etc., but separate designs of these antennas will occupy a relatively large space.
