Unit 30, the two partly overlaps, and is formed in together on substrate 10.
The substrate 10 is the shell of wireless communication device, and in the preferred embodiment, which is metal material.The day
The radiating element 30 and feed-in unit 50 of cable architecture 100 are formed directly on the substrate 10 as wireless communication device shell, can
Manufacturing cost is reduced, and reduces the space for occupying wireless communication device.
The radiating element 30 be slot antenna, substantially be in U-typed comprising the first radiant section 31, the second radiant section 33 and
Linkage section 35.First radiant section 31, the second radiant section 33 and linkage section 35 are in strip, wherein the second radiant section 33 is grown
Degree is slightly shorter than the first radiant section 31, the setting of the two parallel interval, and wherein one end flush.The linkage section 35 and the first radiant section
31 and second the concordant one end of radiant section 33 be vertically connected, form the U-typed radiating element 30.
The feed-in unit 50 is used for and the signal feed-in point on the circuit board of wireless communication device（It is not shown）It is electrically connected,
Think 30 FD feed of radiating element.
In the preferred embodiment, which includes main paragraph 51 and the bifurcated extended to form by the main paragraph 51
Section 53.The main paragraph 51 is substantially in strip comprising is set to feed side 511 and first overlapping ends at 51 both ends of main paragraph
513.The feed side 511 is to FD feed.First overlapping ends 513 are stacked on radiating element 30.The bifurcated section 53 is substantially
It is L-shaped comprising the first bending segment 531 and the second bending segment 533 being vertically connected with first bending segment 531.This first
Bending segment 531 is extended vertically by 51 side of main paragraph and is formed.Second bending segment 533 is by the first bending segment 531 far from main paragraph 51
One end vertically bending and along the direction of parallel first bending segment 531 extend one section formation.Second bending segment 533 is far from first
One end of bending segment 531 forms the second overlapping ends 535.
The feed-in unit 50 is stacked at radiating element 30, and specifically, main paragraph 51 and the second bending segment 533 are respectively perpendicular folded
Be put in the first radiant section 31 and the second radiant section 33, wherein the first overlapping ends 513 and the second overlapping ends 535 respectively with the first spoke
It penetrates section 31 and the second radiant section 33 partly overlaps.To main paragraph 51 and the first radiant section 31, bifurcated section 53 and the second radiant section
32 are respectively formed a signal feed-in path, to improve the bandwidth of radiating element 30.
Also referring to Fig. 2, in the preferred embodiment, the low-frequency range bandwidth of antenna structure 100 is covered up to 100MHz
GSM850 or GSM900 frequency ranges, high band bandwidth cover DCS/PCS/UMTS2100/LTE2300/LTE2500 up to 860MHz
Frequency range, at the same it is verified, and the efficiency of antenna structure 100 is also higher.
