Electric, two feed arms 52 can be respectively electrically connected to two feed arms 52.
Mobile terminal further includes two side frames 6, and two side frames 6 are located at the both sides of the edge of mobile terminal；Two sides
Frame 6 is bent to form by the both sides of the edge of metal back cover 3 towards front shell assemblies 1, i.e., side frame 6 is also made of metal material, and side frame 6 is
A part of metal back cover 3, the two are an integral structure, and be can be further improved mobile terminal complete machine structure intensity, are made simultaneously
It obtains side frame 6 and metal back cover 3 balances transition, guarantee that mobile terminal shape is succinct.
Spacing between metal routing 51 and metal back cover 3 is greater than the spacing between metal routing 51 and front shell assemblies 1, gold
Belong to the relatively close front shell assemblies 1 of cabling 51 to further decrease so that the interval between metal routing 51 and metal back cover 3 is larger
Influence of the metal back cover 3 to metal routing 51, and then reduce influence of the metal back cover 3 to 5 performance of antenna.
Grounding point (not shown) is provided on mainboard 2；Antenna 5 further includes grounding arm 53, one end of grounding arm 53 with
Metal routing 51 is connected, and the other end is electrically connected with grounding point.By the way that metal routing 51 to be grounded, antenna can be further improved
5 performances.Metal back cover 3 is electrically connected with the ground connection of mainboard 2, and metal back cover 3 is allowed to form one that mobile terminal refers to ground
Point.
The antenna 5 of mobile terminal of the present invention may be simultaneously operated in low frequency and high frequency, by adjusting the ruler of metal routing 51
Very little and shape can cover several frequency ranges, such as low frequency 1, low frequency 2, low frequency 3, high frequency 1, high frequency 2 and high frequency 3, these frequency ranges
It can satisfy the performance requirement of the various network formats of the following mobile terminal, figure elaborates inventive antenna one of which operating mode
Corresponding S11 (return loss) parameter respectively corresponds low frequency 1, high frequency 1,2 and of high frequency at the low ebb of parameter cabling from left to right
High frequency 3, it can be seen that can support low frequency 1, high frequency 1, high frequency 2 and high frequency 3 when the operating mode simultaneously.
Fig. 4 to Fig. 7 elaborates a kind of Working mould that the metal routing 51 of the antenna 5 of the specific embodiment of the invention is formed respectively
Formula corresponds to the surface current distribution of low frequency 1, high frequency 1, high frequency 2 and high frequency 3.From the point of view of Surface current distribution in figure, low frequency and
The surface current of high frequency is all mainly distributed on metal routing 51, and the current distribution of metal back cover two sides is less, is held mobile whole
It is less on the influence of 5 performance of antenna when end (mainly holding the side frame of mobile terminal two sides), therefore use antenna 5 of the present invention
The hand of the mobile terminal of system damages and head damage is all relatively small, and the loss of right-hand man and left and right head is all more balanced, can be with
Meets the needs of 5 performance of antenna is continuously improved in the following mobile terminal well.
