[detailed description of the invention]
Fig. 1 is schematically shown as the first embodiment schematic diagram of multifrequency antenna of the present invention.With reference to Fig. 1, multifrequency antenna 100 includes first
Radiation component the 110, second radiation component 120 and the 3rd radiation component 130.Wherein, the first radiation component 110 is in order to produce the first resonance road
Footpath, to cause multifrequency antenna 100 to be operable in the first resonance bands (such as, 700MHz～960MHz).First radiation component 110 with
Second radiation component 120 is in order to produce the second resonance path, to cause multifrequency antenna 100 to be operable in the second resonance bands (such as,
1700MHz～2100MHz).First radiation component 110 and the 3rd radiation component 130 are in order to produce the 3rd resonance path, to cause multifrequency
Antenna 100 is operable in the 3rd resonance bands (such as, 2,5GHz～2,6GHz).
Further to seeing, the first radiation component 110 has the first end TM11, the second end TM12 and the 3rd end TM13.Wherein,
Second end TM12 of the first radiation component 110 has a load point FP, and the 3rd end TM13 of the first radiation component 110 has a ground connection
Point GP.Additionally, the 3rd radiation component 130 has the first end TM31 and the second end TM32, and the second end TM32 of the 3rd radiation component 130
It is electrically connected to ground plane 140.
First radiation component 110 receives feed-in signal through load point FP, and is electrically connected to a ground connection through earth point GP
Face 140.Additionally, the first radiation component 110 overlaps in a vertical plane (such as: X-Y plane) upper part with ground plane 140.Change
Yan Zhi, multifrequency antenna 100 is essentially an inverted F shaped antenna (inverted-F antenna).Furthermore, when the first radiation component 110
When receiving feed-in signal through load point FP, permeable first to the 3rd resonance path is inspired three by multifrequency antenna 100
Resonance mode, and now the first end of the first radiation component 110 and the first end of the 3rd radiation component 130 all have maximum and dissipate energy
Intensity.Additionally, the friendship of now multiple radiation patterns that the first end of the first radiation component 110 and the 3rd radiation component 130 is given off
Repeatedly region is in a preset range.
In other words, multiple radiation patterns that the first to the 3rd radiation component 110～130 is given off are generally to be separated by come
