Problems solved by technology

[0003] The appearance design of this metal back cover is very good for designers and end users, but there is a challenge for antenna engineers, because electromagnetic waves cannot penetrate metal, so a completely closed metal back cover is very harmful to antenna radiation. It is not feasible, it will directly damage the signal strength of the antenna module and affect the experience of mobile terminal users

Embodiment Construction

[0027] Combine below Figure 1 to Figure 8 The present invention is described in detail.

[0028] like Figure 1-Figure 5 As shown, the mobile terminal 1 provided by the present invention includes a metal casing 10 , a printed circuit board 20 and a liquid crystal screen component 30 arranged in sequence, and the mobile terminal 1 also includes an antenna system 40 .

[0029] The metal shell 10 includes an end 11 and a first notch 12 adjacent to the end 11, a semi-closed notch 21 is provided at a position corresponding to the first notch 12 on the printed circuit board 20, and the printed circuit board 20 includes a semi-closed slot. The first part 22 of the opening 21 near the end part 11 and the second part 23 located on the side of the semi-closed notch 21 away from the end part 11, the printed circuit board 20 also includes an upper end surface 24 facing the metal shell 10 and facing the liquid crystal. The lower end surface 25 of the screen member 30, the semi-closed no...

Abstract

An antenna system includes a dual-band antenna. The invention also provides a mobile terminal comprising the antenna system, which comprises a metal housing, a printed circuit board and a liquid crystal panel component arranged in sequence. The metal housing includes an end portion and a first notch adjacent the end portion, A semi-closed notch is arranged at the position corresponding to the first notch on the printed circuit board, the dual-band antenna is arranged at the semi-closed notch, The dual-frequency antenna is fixed to the semi-closed notch through a plastic filler, and the first notch of the metal shell is aligned, thus solving the problem that the metal shell cannot radiate antenna or the radiated signal is weak, and realizing the radiation to a large extent. The plastic filler comprises ABS resin or PC-ABS resin enhances the impact resistance, heat resistance and low temperature resistance of the antenna.

Description

【Technical field】 [0001] The invention relates to the field of mobile terminals, in particular to an antenna system and mobile terminal equipment using the antenna system. 【Background technique】 [0002] At present, with the popularization of mobile terminal intelligence, consumers have higher and higher requirements for the aesthetic appearance of various mobile terminals. Metal is increasingly recognized by consumers for its beauty and wear resistance, high-quality luster and feel. The appearance design of mobile terminals has been gradually upgraded from cheap plastic material bodies to all-metal bodies. [0003] The appearance design of this metal back cover is very good for designers and end users, but there is a challenge for antenna engineers, because electromagnetic waves cannot penetrate metal, so a completely closed metal back cover is very harmful to antenna radiation. It is not feasible, and will directly damage the signal strength of the antenna module and affe...
