The reflecting plate, the radiating vibrator, and the director are arranged on the base plate. Base of the radiating vibrator is connected to core wire of passed through coaxial connector. Structure of the disclosed assembly is compact. Comparing with traditional single directional radiation vibrator, which is unable to work at higher than double frequency, the invention discloses antenna in type of absorbed at top, which is able to work as high as 5.5 double frequency, and with standing wave less than 1.4.
Description
[technical field]
The present invention relates to the communications field, relate in particular to a kind of top suction type directional radiation antenna in broadband.
[technical background]
Top suction type directional radiation antenna in broadband is mainly used in finishes indoor seamless covering, along with the dependence of people to wireless network, also more and more higher to the demand of top suction type directional radiation antenna in broadband.But for the antenna of directed radiation, bandwidth is to after two frequencys multiplication, just be difficult to directed radiation with same Harmonic Oscillators wideband, also become the bottleneck of design, therefore, it is a very important and necessary direction that research is launched in super wideband directional antenna field.
[summary of the invention]
The present invention is exactly in order to break through the technical bottleneck in this field, a kind of top suction type directional radiation antenna in broadband that only can realize ultrabroad band work with a unit oscillator to be provided.
The present invention is achieved through the following technical solutions:
Top suction type directional radiation antenna in broadband of the present invention, comprise reflecting plate, radiating doublet, at least one director, base plate and coaxial connector, wherein, the longitudinal section of described reflecting plate is T type, described reflecting plate, radiating doublet and director successively arranges and is arranged on the base plate, and the radiating doublet bottom is connected with the heart yearn that passes coaxial connector.
Described radiating doublet comprises cylindrical top and obconic bottom, and described radiating doublet bottom is provided with regulating part to regulate the height of radiating doublet, in addition, is connected with ground strip between radiating doublet and base plate.
Described reflecting plate comprises the support portion of setting and the horizontal part that has been supported by the support portion.
For making effect reach optimum, the radiating doublet upper height is 0.1～0.2 λ, and diameter is 0.3～0.6 λ, and the bottom height is 0.08～0.2 λ, and subtended angle is 90～120 °, and λ is the centre frequency wavelength.The horizontal part of described reflecting plate and the vertical range of radiating doublet are 0.05～0.15 λ, and height is 0.3～0.6 λ, and λ is the centre frequency wavelength.
Require difference according to lobe, described director is more than two, and arranges successively.
Described base plate is provided with radome, and radome is covered with described reflecting plate, radiating doublet, ground strip, director in it.
Compared with prior art, the present invention possesses following advantage: combination of the present invention is made up of T shape reflecting plate, radiating doublet, director and base plate, simple for structure, having broken through in the past, the single directional radiating doublet can't work in the above technical bottleneck of two frequencys multiplication, for the research field of super wideband directional antenna provides a kind of feasible and reliable solution, can provide a kind of up to 5.5 frequency multiplication standing internal waves less than 1.4 ceiling mount antenna.

[embodiment]
The present invention is further illustrated below in conjunction with drawings and Examples:
See also Fig. 1 and 2, the present invention includes reflecting plate 1, radiating doublet 2, director 3 and the base plate 4 of metal material, described reflecting plate 1, radiating doublet 2, director 3 are arranged according to precedence and are arranged on the base plate.
Described radiating doublet 2 is a metal group component, comprises cylindrical top and obconic bottom.In addition, also set up the bottom that a cylinder regulating part 6 is connected in radiating doublet 2, can regulate the height that radiating doublet 2 departs from base plate 4 by regulating this regulating part 6; Between base plate 4 and radiating doublet 2, also have additional two ground strips 8 in both sides, the one end is connected on the radiating doublet 2, and the other end then is fixed on the base plate 4.
In a side of radiating doublet 2, also be placed with 3, two directors 3 of two described directors and one in front and one in back be provided with.
Described base plate 4 is the disk shape, and its corresponding described regulating part 6 places offer through hole, through hole bottom installing coaxial connector 7, and thus, the heart yearn of coaxial connector 7 can pass these base plate 4 through holes and be connected with the bottom of radiating doublet 2.T type reflecting plate 1 usefulness screw 13 is fixed on the base plate 4.Two directors 3 also are screwed on base plate 4, require difference according to lobe, and the quantity of director 3 is also different with size.
In addition, also be provided with a radome 9,, described reflecting plate 1, radiating doublet 2, director 3 and ground strip 8 etc. be located in itself and the base plate 4 formed spaces with base plate 4 locking.
When the various sizes of the top of radiating doublet 2 and bottom reach certain ratio, implementation result of the present invention is more excellent, is specially: radiating doublet 2 top height are 0.1～0.2 λ, and diameter is 0.3～0.6 λ, the bottom height is 0.08～0.2 λ, and taper subtended angle in bottom is 90～120 °; The horizontal part 12 of reflecting plate 1 is 0.05～0.15 λ with the vertical range of radiating doublet 2, and height is 0.3～0.6 λ; Wherein λ is the centre frequency wavelength.The product structure figure that goes out by this size design can consult shown in Figure 3.
By the sample (consulting Fig. 3) that above-mentioned execution mode constitutes, in 780～4300MHz frequency range, horizontal radiation pattern is at 120 ° ± 10 °, and greater than 8dB, the actual measurement gain is surveyed maximum standing-wave ratio less than 1.4 greater than 5.0dBi than index in front and back.Therefore, this execution mode can solve the technical bottleneck of super wideband.
Find out that easily this antenna will have strong, the simple and compact for structure and high performance advantage of ambient adaptability made in accordance with the present invention, and be easy to make, cheaply and conveniently install and use.
