Side S1 only connects the outer side edges of the signal feed-in part 102 of a part, and the 3rd side S3 of the 3rd connecting portion 108 only connects one
The outer side edges of partial grounding parts 104.
The second side S2 of the vertical connection second connecting portion 106 of first irradiation unit 110, and with first connecting portion 100, signal
Feeding portion 102 is parallel to each other but not overlapping with grounding parts 104.The 4th of the connecting portion 108 of second irradiation unit, 112 vertical connection the 3rd
Side S4, that is, the second irradiation unit 112 is parallel but is not overlapped in first connecting portion 100, signal feed-in part 102 and grounding parts 104
The plane formed.In other words, the angle and the second spoke formed between the first irradiation unit 110 and second connecting portion 106
It is all 90 degree to penetrate between the connecting portion 108 of portion 112 and the 3rd angle formed, and the first irradiation unit 110 and the second irradiation unit
112, which are directed towards the direction away from first connecting portion 100, is formed.In in practice, the first irradiation unit 110 and the second irradiation unit 112
There is a gap between substrate 4, in other words, the first irradiation unit 110 and the second irradiation unit 112 are not in contact with to substrate 4.
In more detail, the first irradiation unit 110 and the second irradiation unit 112 all (can also claim " recessed " in a kind of " ㄈ " type structure
Type structure), and there is breach 114a and breach 114b, described breach 114a direction and breach 114b direction all courts respectively
To first connecting portion 100.Therefore, the first irradiation unit 110 can more include the first sub- irradiation unit 1100, the second sub- irradiation unit
1102 and the 3rd sub- irradiation unit 1104, wherein the first sub- 1100 and second sub- irradiation unit 1102 of irradiation unit is respectively by the 3rd sub- spoke
The opposite end for the inner side edge S10 for penetrating portion 1104 extends and is parallel to each other, and the first sub- irradiation unit 1100 connects a part
Second side S2.Similarly, the second irradiation unit 112 can more include the 4th sub- irradiation unit 1120, the 5th sub- irradiation unit
1122 and the 6th sub- irradiation unit 1124, wherein the 4th sub- 1120 and the 5th sub- irradiation unit 1122 of irradiation unit is respectively by the 6th sub- spoke
The opposite end for the inner side edge S16 for penetrating portion 1124 extends and is parallel to each other, and the 4th sub- irradiation unit 1120 connects a part
Four side S4.
Breach 114a by the inner side edge S6 of the first sub- irradiation unit 1100, the inner side edge S10 of the 3rd sub- irradiation unit 1104 and
The inner side edge S8 of second sub- irradiation unit 1102 is surrounded and formed；Breach 114b by the 4th sub- irradiation unit 1120 inner side edge S12,
The inner side edge S14 of the sub- irradiation units 1122 of inner side edge S16 and the 5th of six sub- irradiation units 1124 is surrounded and formed.
In the embodiment of the present invention, the distance between outer side edges S9 and inner side edge S10 of the 3rd sub- irradiation unit 1104 length
The distance between outer side edges S5 and inner side edge S6 more than the first sub- irradiation unit 1100 length and the second sub- irradiation unit 1102
The distance between outer side edges S7 and inner side edge S8 length；Between the outer side edges S15 and inner side edge S16 of 6th sub- irradiation unit 1124
Distance length is more than the distance between the outer side edges S11 and inner side edge S12 of the 4th sub- irradiation unit 1120 length and the 5th sub- spoke
Penetrate the distance between the outer side edges S13 and inner side edge S14 in portion 1122 length.

Due to the return loss of Anneta module 1, standing wave ratio (standing wave ratio, SWR) and Smith chart (smith
Chart) known by art tool usually intellectual, therefore no longer especially repeat.
In addition, when the Anneta module 1 of the present invention operates in 5.15GHz, the average gain (average of Anneta module 1
Gain) it is -1.53dB, its peak gain ratio (peak gain) is 4.81dBi, and its efficiency (efficiency) is 70.21%；When
When Anneta module 1 operates in 5.35GHz, the average gain of Anneta module 1 is -1.31dB, and its peak gain ratio is 5.21dBi,
Its efficiency is 73.82%；When Anneta module 1 operates in 5.825GHz, the average gain of Anneta module 1 is -1.22dB, its point
The peak ratio of gains is 5.82dBi, and its efficiency is 75.44%；When Anneta module 1 operates in 5.875GHz, Anneta module 1 is averaged
Gain is -1.47dB, and its peak gain ratio is 5.65dBi, and its efficiency is 76.66%.In in practice, Anneta module 1 of the invention
Working band it is rough between 5.15GHz~5.875GHz, in other words, the first resonance bands and the second resonance bands are through folded
Closing formed working band can be between 5.15GHz~5.875GHz, but is not limited.
In summary described, the embodiment of the present invention provides a kind of wireless transmitter and its Anneta module, and it passes through structure
Design allow Anneta module have the first resonance bands current path and the second resonance bands current path, and
First resonance bands partly overlap the second resonance bands so that Anneta module can have a kind of larger working band and shape
Into a kind of single-band antenna.Whereby, wireless transmitter of the invention and its Anneta module solve the problems, such as that impedance matching is not easy,
And the degree of difficulty and manufacturing cost of manufacture are reduced, very with practicality.
Certainly, the present invention can also have other various embodiments, ripe in the case of without departing substantially from spirit of the invention and its essence
Various corresponding changes and deformation, but these corresponding changes and deformation can be made according to the present invention by knowing those skilled in the art
The protection domain of the claims in the present invention should all be belonged to.
