300 is similar to dual-band antenna 100, except the first Department of Radiation 302 of dual-band antenna 300 includes that first is curved
Folding part 3022, the second Department of Radiation 304 includes the second kink 3042.As shown in figure 3, the first radiation
After the one end of portion 302 extends toward second direction D2, its terminal then extends with shape towards the second Department of Radiation 304
Into the first kink 3022.Therefore, the first Department of Radiation 302 is the rough metal patterns in ㄈ fonts.Its
In, the first kink 3022 and the second Department of Radiation 304 are at a distance of one second interval G2 '.
On the other hand, reverse (towards figure in below) of the one end of the second Department of Radiation 304 toward second direction D2
After extension, then extend to form the second kink 3042 towards the first Department of Radiation 304.Wherein, the second bending
The terminal in portion 3042 is with the first Department of Radiation 302 at a distance of one the 3rd interval G3 '.
With previous embodiment similarly, the first Department of Radiation 302 includes one end of the first feeding portion F1 ' and the
Two Departments of Radiation 304 include that one end of the second feeding portion F2 ' is least partially overlapped.Wherein, the first feeding portion
F1 ' and the second feeding portion F2 ' is at a distance of one first interval G1 ', and the first interval G1 ', the second interval G2 '
And the 3rd interval both G3 ' wherein at least it is different each other.
It is noted that also may be used according to the dual-band antenna 100,200,300 disclosed by the embodiment of the present invention
A variety of deformations are produced by combination, replacing section structure.For example, dual-band antenna 100,
200 the first kink 1022 and the first kink 3022 of dual-band antenna 300 can phase double replacements, double
The metal patch 2042 of frequency antenna 200 also can mutually be put with the second kink 3042 of dual-band antenna 300
Change and dual-band antenna 100 is optionally plus the second kink 3042 of such as dual-band antenna 300
Deng the category of this little deformation all category spirit of the present invention.
In sum, dual-band antenna provided by the present invention is set two radiation branches based on dipole antenna framework
It is set to part projection to overlap to inspire another resonance mode, antenna is carried out dual frequency operation.Antenna sets
Meter person can be easily adjusted day by changing the length of projection lap and/or the structure of radiation branch
The operating frequency of line.Additionally, dual-band antenna provided by the present invention possesses dipole antenna configuration simply, gently
Skilful advantage, therefore various communication electronics product can be bound to according to different application demand.
Although disclosing the present invention with reference to preferred embodiment above, but it is not limited to the present invention.
