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.
Main part 11 extends upward one second antenna part 13 in the middle part at first edge, this second antenna part 13 works in lower band, as GSM (825MHz) and EGSM (900MHz) frequency band etc.This second antenna part 13 has a junction 131 and Department of Radiation 132.Connecting portion 131 extends out vertically upward from the middle part at main part 11 first edges, and this connecting portion 131 is rectangular tabular, and its width is greater than the width of first antenna part 12, and its height is less than the height of first antenna part 12.Connecting portion 131 and 12 of first antenna parts are separated with a separate slot 14.Department of Radiation 132 upwards and to the direction away from first antenna part 12 extends out from connecting portion 131 ends, and this Department of Radiation 132 is rectangular tabular, and the ora terminalis and first antenna part 12 is terminal substantially flush on it.Second antenna part 13 and first antenna part 12 mutual interference mutually when avoiding receiving and transmitting signal, excise a rectangular area and form a breach 1321 at contiguous first antenna part in the upper left corner of Department of Radiation 132 12 places.
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.
The utility model multifrequency antenna 1 in use can be according to the bending rational in infrastructure of hand-held electronic product, takes up room with minimizing and satisfies the demand of hand-held electronic product miniaturization.See also Fig. 2 and Fig. 3, a kind of antenna assembly 2 of using above-mentioned multifrequency antenna 1 is installed in the hand-held electronic product, and it comprises a support 21, and support 21 is the hollow cuboid of a bottom surface opening.Multifrequency antenna 1 bending is installed in the surface of support 21, wherein, first antenna part 12 and second antenna part 13 are fixed on the end face of support 21, main part 11 is fixed on the side of support 21, and the bend inwards bottom surface that places support 21 of 16 of feeding portion 15 and grounding parts connects with circuit board or directly is welded on the corresponding circuit board with convenient.
Multifrequency antenna 1 can be fixed on the support 21 with binder.In addition, can be in the projection positioning hole corresponding on the insulation shell of offering on multifrequency antenna 1 and the support 21 with hand-held electronic product, after being inserted location hole, projection utilize hot melting mode that projection and antenna assembly 2 are fixed together, thereby antenna assembly 2 is fixed on the insulation shell of hand-held electronic product, can be more accurately electrically connects with the circuit board of hand-held electronic product to guarantee antenna assembly 2.
Antenna assembly 2 utilizes fixedly multifrequency antenna 1 of support 21, and has strengthened the structural strength of multifrequency antenna 1, has reduced multifrequency antenna 1 occupation space.In addition, the electronic devices and components of the hollow region of support 21 inside on can also containment circuit board, thus can further save the space, and then make the hand-held electronic product miniaturization.
In sum, the utility model multifrequency antenna 1 and the antenna assembly 2 of using this multifrequency antenna 1 not only can be worked in a plurality of frequency band ranges, and this multifrequency antenna 1 cooperates antenna assembly 2 can reduce occupation space effectively, reduces and takes up room and increase the problem that frequency range can not be taken into account simultaneously thereby solved the prior art antenna.
