Wherein, the first metal portion of the first antenna is a straight portions, and the second metal portion of the first antenna is one
Straight portions, and the length of the first metal portion of the first antenna is greater than the length of the second metal portion of the first antenna.
Wherein, the first metal portion of second antenna is the first metal portion and the second metal positioned at the first antenna
Between portion, the second metal portion of second antenna be positioned at the first antenna the first metal portion and the 4th metal portion it
Between.
Brief description of the drawings
To further illustrate the above-mentioned purpose, design feature and the effect that confirm the present invention, below with reference to accompanying drawing to this hair
It is bright to be described in detail, wherein：
Fig. 1 shows antenna configuration schematic diagram of the communication device in an angle of the embodiment of the present invention.
Fig. 2 shows the communication device of the embodiment of the present invention from the antenna configuration schematic diagram of another view.
Embodiment
Fig. 1 and Fig. 2 shows that the communication device 10 of the embodiment of the present invention includes a metal shell 12, and the metal shell 12 has
One first side 14a, a second side 14b position correspondences are in first side 14a and a gap 15.
The antenna configuration of the communication device 10 includes a first antenna 16 and one second antenna 18.The first antenna 16 is wrapped
Containing one first metal portion 20, one second metal portion 22, one the 3rd metal portion 24 and one the 4th metal portion 26.Preferably implement one
In example, first metal portion 20 is a straight portions, and second metal portion 22 is also a straight portions, and the length of first metal portion 20
Degree is greater than the length of second metal portion 22.
3rd metal portion 24 is that extension is connected between first metal portion 20 and second metal portion 22.It is preferable one
In embodiment, the 3rd metal portion 24 is the first side 14a positioned at the adjacent metal shell 12.
In a preferred embodiment, the 4th metal portion 26 is to connect the second side 14b of the metal shell 12.
First metal portion 20, second metal portion 22, the 3rd metal portion 24 and the common definition of the 4th metal portion 26
One antenna trace.The gap 15 of aforementioned metal housing 12 be between the metal shell 12 and the first antenna 16, make this
One antenna 16 will not be short-circuited, and therefore, the shaped formation mode in the gap 15 does not limit to the state disclosed in the embodiment of the present invention
Sample.
