Two of the purpose of this utility model is antenna assemblies that the little and bandwidth of a kind of volume is provided at the defective that above-mentioned prior art exists.
One of for achieving the above object, multifrequency antenna provided by the utility model comprises a main part, one first antenna part, one second antenna part, a feeding portion and a grounding parts.This main part has first edge and second edge, offers a fluting on the main part.This first antenna part forms from an end vertical extent at first edge.This second antenna part has a connecting portion with first antenna part interval, one distance that extend from first edge-perpendicular and reaches by the connecting portion end towards the Department of Radiation that extends away from the direction of first antenna part.This feeding portion is stretched at an epitaxial lateral overgrowth of fluting by second edge and is formed.This grounding parts is stretched out at the opposite side of slotting by second edge and forms.
Because multifrequency antenna comprises first antenna part and second antenna part, thereby the utility model multifrequency antenna can be received and dispatched the signal of a plurality of frequency bands, and first antenna part comes out from an end vertical extent at first edge, second antenna part have extend from first edge-perpendicular with first antenna part at interval a distance connecting portion and by the connecting portion end towards the Department of Radiation that extends away from the direction of first antenna part, thereby the utility model multifrequency antenna occupation space is little.
For achieving the above object two, the utility model also provides a kind of antenna assembly, it comprises a support and a multifrequency antenna.Multifrequency antenna comprises a main part, one first antenna part, one second antenna part, a feeding portion and a grounding parts.This main part has first edge and second edge, offers a fluting on the main part.This first antenna part forms from an end vertical extent at first edge.This second antenna part has a connecting portion with first antenna part interval, one distance that extend from first edge-perpendicular and reaches by the connecting portion end towards the Department of Radiation that extends away from the direction of first antenna part.This feeding portion is stretched at an epitaxial lateral overgrowth of fluting by second edge and is formed.This grounding parts is stretched out at the opposite side of slotting by second edge and forms.Wherein, this multifrequency antenna bending is installed on the support.
Because multifrequency antenna can be received and dispatched the signal and the bending of a plurality of frequency bands and be installed on the support, thereby little, the bandwidth of the volume of the utility model antenna assembly.

Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
See also Fig. 1, the utility model multifrequency antenna 1 is formed by the Copper Foil etching on the flexible circuit board 3, and it comprises a roughly rectangular tabular main part 11.This main part 11 has two relative first edge (not indicating) and second edge (not indicating).Main part 11 extends upward first antenna part 12 that is strip by the end at first edge.This first antenna part 12 works in high frequency band, as DCS (1800MHz), PCS (1900MHz) and WCDMA (2000MHz) frequency band etc.
The fluting 17 that second edge of main part 11 offers one " L " shape away from an end of first antenna part 12, and this second edge extends a feeding portion 15 and a grounding parts 16 downwards respectively in the both sides of fluting 17.In addition, have good electrical conductivity, all be coated with Gold plated Layer on this feeding portion 15 and the grounding parts 16 for making feeding portion 15 and grounding parts 16.The utility model multifrequency antenna 1 can reach by the degree of depth (promptly adjusting the height of first antenna part 12 and second antenna part 13 and the height of feeding portion 15 and grounding parts 16) of adjusting separate slot 14 and fluting 17 regulates first antenna part 12 and the voltage standing wave ratio of second antenna part 13 and the effect of frequency coverage thereof, thereby makes the voltage standing wave ratio of multifrequency antenna 1 and frequency covering scope reach the optimum Match state.
Because multifrequency antenna 1 comprises first antenna part 12 and second antenna part 13, thereby the utility model multifrequency antenna 1 can be received and dispatched the signal of a plurality of frequency bands, and first antenna part 12 comes out from an end vertical extent at first edge, second antenna part 13 have extend from first edge-perpendicular with first antenna part 12 at interval a distance connecting portion 131 and by connecting portion 131 ends towards the Department of Radiation 132 that extends away from the direction of first antenna part 12, thereby the utility model multifrequency antenna 1 occupation space is little.
