Tie point it is identical.It should be appreciated that two above-mentioned tie points can also be different.
Preferably, the metal back cover 1 includes cover plate 14 and two sides 15.Two sides 15 are separately positioned on cover plate 14
Both sides.In general, metal back cover 1 are rectangle, then two sides 15 are rectangular long side.The gap 11 may be provided at lid
On plate 14 or side 15.When the gap 11 is arranged on cover plate 14, the gap 11 can be specially opened up on cover plate 14.Side
Function key perforate would generally be set, when the gap 11 is arranged on into side according to the demand of the mobile terminal where antenna on side 15
When on side 15, because the gap 11 is closed loop gap, therefore can be without specially opening up gap 11 on side 15.The gap 11 can
Think the gap that the function key perforate of metal back cover 1 is formed so that gap 11 can be integrated with structural member, improve antenna
The disguise of system, while also saved design space for equipment.Further, since the antenna of prior art is commonly located closer to move
The top of dynamic terminal or the position of bottom, the present embodiment realizes antenna by this intrinsic function key perforate, with existing skill
The position of the antenna of art is compared, (example when mobile terminal user takes phone or when gripping mobile terminal progress application operating
Mobile terminal is such as gripped to be played), the antenna of the present embodiment is relatively distant from the head of mobile terminal user or grips movement
The hand of terminal, it relative can so avoid head from either holding the influence of (horizontal hold or perpendicular hold) for antenna performance, be lifted
Antenna performance.And can be that antenna system of multiple-input and multiple-output form etc. provides arrangement space.The function key perforate is for example
Can be volume key perforate, key perforate etc..
To sum up, the antenna of the utility model first embodiment, by setting resonance piece 4 can be with the gap 11 of excitation closed-loop
Radiation mode, radiation is produced using the gap 11 of complex match and closed loop, the flexible layout degree of antenna can be improved；In addition, the seam
Gap 11 can utilize the function key perforate in metal back cover 1 to be formed, so that gap 11 can be integrated with structural member, carry
The high disguise of antenna system, while design space also has been saved for equipment, and due to the position of antenna arrangement, can make
What antenna was tried one's best avoids human body, influence of the human organ for antenna performance is diminished.
Second embodiment
The utility model second embodiment provides a kind of antenna.As shown in Figures 3 and 4, the structure of the antenna and the first reality
It is identical to apply the structure of the antenna of example, except that, the antenna also includes：Adjusting switch 5.Adjusting switch 5 is arranged on seam
In gap 11.One end of adjusting switch 5 is connected with first side 113 in gap 11, the other end of adjusting switch 5 and the second of gap 11
Side 114 connects, and connects main reference ground 13.For example, as shown in figure 3, the other end of the adjusting switch 5 and second side in gap
114 tie point is connected by connecting line with main reference ground 13.
The adjusting switch 5 can play a part of the frequency band of expansion antenna by disconnection or short-circuit.Specifically, when regulation
When switch 5 disconnects, the effective length in gap 11 arrives the length at second end 112 in gap 11 for the first end 111 in gap 11.Work as tune
During section 5 closure of switch, adjusting switch 5 divides in gap 11 for first paragraph gap and second segment gap.Wherein, resonance piece 4 is vacantly set
Put on first paragraph gap.The effective length in gap 11 is the length in first paragraph gap.For example, as shown in figure 4, work as adjusting switch
During closure, the effective length in gap 11 arrives the length of adjusting switch 5 for the first end 111 in gap 11.As shown in figure 5, it is the day
The simulation result figure of line.
