The utility model is described in further detail with reference to the accompanying drawings and examples.It is understood that herein
Described specific embodiment is used only for explaining the utility model, rather than limits of the present utility model.Further need exist for
It is bright, for the ease of description, the part related to the utility model rather than entire infrastructure are illustrate only in accompanying drawing.
First embodiment
Present embodiments provide a kind of technical scheme of ultra wide band wall aerial.Referring to Fig. 1, ultra wide band wall aerial bag
Include：The integrally formed a period of time piece 31,32 of first a period of time piece, 11,12, second a period of time piece the 21,22, the 3rd, and reflecting plate 41.
Reflecting plate 41 is arranged on the bottommost of whole ultra wide band wall aerial, and the electromagnetic wave for will be radiated to itself is anti-
Penetrate so that the wave beam of antenna concentrates on a direction.
On reflecting plate 41, matching component 5 is additionally provided with.The effect of matching component 5 be to realize each a period of time piece with
Impedance matching between feeder.Matching component 5 is fixed on reflecting plate 41 self by the screw on reflecting plate 41.
Second a period of time piece 21,22 and the 3rd a period of time piece 31,32 be arranged in parallel with reflecting plate 41 respectively.They are by conduction material
Material is made, the radiation for electromagnetic wave.
For second a period of time piece 21,22, the 3rd a period of time piece 31,32 is closer to reflecting plate 41.3rd a period of time piece
Including the 5th a period of time sub-pieces 31, and the 6th a period of time sub-pieces 32.5th a period of time sub-pieces 31 and the 6th a period of time sub-pieces 32 are on reflection
The centre normal axial symmetry of plate 41.
5th a period of time sub-pieces 31 and the 6th a period of time sub-pieces 32 have relatively large surface area.In order to ensure above-mentioned two
The firm connection of sub-pieces, in the center of the 5th a period of time sub-pieces 31 and the 6th a period of time sub-pieces 32, by screw by them and instead
Plate 41 is penetrated to fix.5th a period of time sub-pieces 31 should be equal apart from the height of reflecting plate 41 with the 6th a period of time sub-pieces 32.Also, the 5th
A period of time sub-pieces 32 of a period of time sub-pieces 31 and the 6th should be higher than the height of itself of matching component 5 apart from the height of reflecting plate 41.
Identical with the 3rd a period of time piece 31,32, second a period of time piece 21,22 equally also includes the center two on reflecting plate 41
The axisymmetric a period of time sub-pieces of normal.The two a period of time sub-pieces are known respectively as the 3rd a period of time sub-pieces 21 and the 4th a period of time sub-pieces 22.
Relative to the 5th a period of time sub-pieces 31 and the 6th a period of time sub-pieces 32, the surface area of the 3rd a period of time sub-pieces 21 and the 4th a period of time sub-pieces 22 compared with
It is small.Because surface area is smaller, for the 5th a period of time sub-pieces 31 and the 6th a period of time sub-pieces 32, the use screw set thereon
Firm tie point it is also less.
First a period of time piece 11,12 is constituted by two in a period of time sub-pieces of herringbone shape.The two a period of time sub-pieces respectively by
Referred to as first a period of time sub-pieces 11 and second a period of time sub-pieces 12.It is with second and third a period of time piece something in common, constitutes first gust
Two a period of time sub-pieces of sub-pieces, that is, first a period of time sub-pieces 11 and second a period of time sub-pieces 12 are also with regard to the center of reflecting plate 41
Normal axial symmetry.
The upper edge and the side edge of the 3rd a period of time sub-pieces 21 of first a period of time sub-pieces 11 are affixed.From the 3rd a period of time sub-pieces 21
Above-mentioned side edge, first a period of time sub-pieces 11 diagonally downward, and extends to one end of matching component 5.That is, first a period of time
The other end of sub-pieces 11 is in contact with one end of matching component 5.
Corresponding, the upper edge and the side edge of the 4th a period of time sub-pieces 22 of second a period of time sub-pieces 12 are affixed.From the 4th gust
The side edge of sub-pieces 22, second a period of time sub-pieces 12 diagonally downward, and extends to the end of matching component 5.
Because two a period of time sub-pieces for constituting first a period of time piece 11,12 have an above-mentioned structure matching, first a period of time piece 11,
12 form bell-mouth structure of air between reflecting plate 41.Due to the setting of this bell-mouth structure of air, the gain ten to improving antenna
Divide favourable.
In first a period of time sub-pieces 11 and second a period of time sub-pieces 12, the first column adjuster 61 and are also respectively provided with
Two column adjusters 62.The effect of two column adjusters 61,62 is：Adjust first a period of time sub-pieces 11 and second a period of time sub-pieces
12 standing wave.In the working frequency range of above-mentioned two a period of time sub-pieces, electric current is a maximum at two column adjusters 61,62
Point, forms standing wave crest.Set after column adjuster 61,62, portion of electrical current can flow to adjusting rod, the energy reduced herein is anti-
Penetrate, so that reaching improves the purpose of standing wave.
In the present embodiment, first 11,12, second a period of time piece 21,22 of a period of time piece and the 3rd a period of time piece 31,32 are integrated
Shaping.Screw that centre is used, the secure component of stud are the purposes for local stiffening, are not because between above-mentioned part
It is the part of separation.Fig. 2 shows the partial structurtes for the ultra wide band wall aerial that the present embodiment is provided.Referring to Fig. 2, show in figure
Between all parts gone out and in the absence of gap, that is to say, that all parts are integrally formed and manufactured.
First a period of time piece mainly completes 1.7GHz to the frequency coverage of 3.5GHz frequency ranges, and second a period of time piece is mainly realized
0.7GHz is to the frequency coverage of 1.7GHz parts, and the 3rd a period of time piece then completes 0.35GHz to the frequency coverage of 0.7GHz frequency ranges.
It should be noted that the coupling between first 11,12, second a period of time piece 21,22 of a period of time piece and the 3rd a period of time piece 31,32
Conjunction is capacitive coupling.The generation of passive intermodulation between different a period of time pieces can be avoided using capacitive coupling.
In the ultra wide band wall aerial that the present embodiment is provided, the non-co-planar structure of multilayer is employed, this will be to improving space
Utilization rate so that antenna inherently more minimizes highly beneficial.
The present embodiment is real by the non-co-planar structure of multilayer between first a period of time piece, second a period of time piece and the 3rd a period of time piece
Low cost, the directional diagram oriented cover of ultra wide band are showed.
Second embodiment
Present embodiments provide another technical scheme of ultra wide band wall aerial.Referring to Fig. 3, in the present embodiment, surpass
Broadband wall aerial includes：First a period of time piece 7, second a period of time piece 8, the 3rd a period of time piece 9 of split shaping, and reflecting plate 10.
In addition to split is molded, it is also differ in that with the utility model first embodiment：In second a period of time piece 8
Lower section be additionally provided with the first coupling piece 101.In the edge of second a period of time piece 8, between the 3rd a period of time piece 9, it is additionally provided with
Second coupling piece 102.The effect of first coupling piece 101 is to adjust being coupled as between second a period of time piece 8 and first a period of time piece 7
Capacitive coupling.The effect of second coupling piece 102, which is to adjust between second a period of time piece 8 and the 3rd a period of time piece 9, is coupled as capacitive
Coupling.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this area
For technical staff, the utility model can have various changes and change.All institutes within spirit of the present utility model and principle
Any modification, equivalent substitution and improvements of work etc., should be included within protection domain of the present utility model.
