Description

The improvement of the double frequency of falling F 3 D antenna structure

Technical field

What the utility model relates to that a kind of antenna structure is particularly related to is a kind of strengthening action that is directed to signal reception/emission, make its strengthen power with to energy, and then make it reach the intensity and the scope of preferable frequency range and signal.

Background technology

Existing antenna configuration A mostly is three-dimensional monolithic design, (seeing also Fig. 1) reaches the effect of reception/emission by the above radiant body of plural number, not only volume is excessive causes taking the design space signal frequency range is restricted, and the reception scope is limited to; And the reception of the radiant body influence that also is interfered easily, and then make signal weaken, cause the bad situation of reception to produce.

Existing defective:

Existing antenna is only had simple structure, and signal easily disturbs instability.

Existing antenna is difficult for regulating impedance, is not easy coupling with circuit design.

This case utility model designer is because of existing antenna easily causes above-mentioned problem, so the novel double frequency of the falling F 3 D antenna structure improvement of concentrating on studies out.

Summary of the invention

The purpose of this utility model promptly is to provide a kind of double frequency of falling F 3 D antenna structure improvement that strengthens the double frequency signal effect of reception/emission;

Another purpose of the present utility model promptly is to provide a kind of double frequency of falling F 3 D antenna structure improvement with the double frequency signal scope that strengthens reception/emission;

A purpose more of the present utility model is to be to provide a kind of volume littler, simple in structure, the easy-to-install double frequency of falling F 3 D antenna structure improvement;

The double frequency of the falling F 3 D antenna structure improvement of the above utility model purpose, be up to extend two radiant bodies by grounding parts, and electrically be situated between with coaxial cable and two radiant bodies via load point and connect, use as the three-dimensional gain effect of electromagnetic wave double frequency with its two radiant body, with the frequency range of increase resonance, and then make electromagnetic wave reach complete effect; Fixing hole via grounding parts is fixed on the described double frequency of falling F 3 D antenna structure in the mobile computer again, and with a coaxial cable signal electrically is sent in the circuit of signal reception/emission.

Have the different characteristics of stereo power vector by described dual-band antenna, and then can reach bigger frequency range, better reception scope and effect.

Advantage of the present utility model:

The utility model double frequency three-dimensional antenna, stable difficult interference of three-dimensional modelled signal.

The diverse location that the utility model relies on adjustment signal line and load point to be situated between and to connect forms the impedance matching of regulating dual-band antenna, and letter makes its enhancing or reduces circuit gain.

Embodiment

Below in conjunction with accompanying drawing, to this novel above-mentionedly is described in more detail with other technical characterictic and advantage.

See also Fig. 2～Fig. 4, be the utility model double frequency of falling F 3 D antenna structure improvement 1, be by a grounding parts 2, side configuration fixing hole 3, grounding parts 2 center section parts one side then up extends one first connector 7 (seeing also Fig. 3), it is parallel with grounding parts 2 summarys to extend one second connector 6 via first connector 7, form the 3rd connector 5 via second connector 6 upsets, one angle, one end of described again the 3rd connector 5, vertically extend the 4th connector 52, extend one first radiant body 51 via the 4th connector 52 1 sides again, then extend one second radiant body 53 in the other direction, described first radiant body 51 is to have a kink to be formed on the different 3 D planes with second radiant body 53, to use as the three-dimensional gain effect of electromagnetic wave double frequency, another load point 4 extends setting at second radiant body, 53 1 sides, connect signal line 42 in the coaxial cable 41 in order to electrical Jie, and described signal is sent in reception/radiating circuit, and the diverse location that can rely on adjustment signal line 42 and load point 4 to be situated between and to connect, form the impedance matching of regulating dual-band antenna, make its enhancing or reduce circuit gain.

Again, the described double frequency of falling F 3 D antenna structure improvement 1 is operated in lower frequency with first radiant body 51 and second radiant body 53 is operated in upper frequency, in order to reception/emission signal, and with first connector 7, second connector 6, the 3rd connector 5, the effect that the 4th connector 52 can make the electromagnetic wave waveform impose resonance reaches to add takes advantage of effect, and then obtain better frequency range, yet because of the double frequency of falling F 3 D antenna structure improvement 1 needs effectively to reduce to account for volume to avoid using excessive space, second radiant body 53 is adopted with the flexure type shape and to keep electromagnetic gain intensity effect for some reason.

See also Fig. 5, be another double frequency of falling F three-dimensional antenna embodiment schematic diagram, if need not consider the waveform vector intensity of usage space size and electromagnetic wave reception/emissive porwer, then second radiant body 53 can adopt rectilinear in shape, can be because of being straight length, influence each axially (x axle, the y axle, the z axle) better gain intensity and effect, the 3rd connector 5 produces resonance effect because of need cooperate first radiant body 51, so it is main principle that the 3rd connector 5 shapes need to cooperate second radiant body, described again wherein first radiant body 51 is operated in lower frequency, and second radiant body 53 is operated in upper frequency.

See also Fig. 6 and Fig. 7, its be is measured refraction loss amplitude (RETURNLOSS) figure and standing-wave ratio (VSWR) figure that obtains by DC～7GHZ, is met the high performance requirements of double frequency three-dimensional antenna by graphic obvious the utility model tool.

Above-listed detailed description is specifying at the best possible embodiments of the utility model, only described embodiment is not in order to limit claim of the present utility model, but we are when knowing utilization specification of the present utility model and graphic content and even the many equivalent structures of mutation, former all equivalence enforcement or changes that the utility model skill spirit is done that do not break away from, all should be included in the claim of this case, close and give Chen Ming.

The utility model connector shape is to cooperate radiant body to produce resonance effect, forms better gain intensity and effect.

In sum, this case not only really belongs to innovation on technological thought, and can promote above-mentioned multinomial effect by existing article, shows the legal monopoly important document that should fully meet industry, novelty and progressive, files an application in accordance with the law.

More than explanation is novel just illustrative for this; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection range of the present utility model.
