Above；Say further, when having multiply injection water body, the difference of each post current can be controlled
Highly realize broadband.
As the preferred scheme of one, described inlet port, outlet and coaxial line connector set
There is silica gel sheath.
A kind of injection water body antenna, can be used for shortwave or ultrashort communication.
The present invention has the beneficial effects that:
1, metal antenna bulky dimensions, weight are relatively big, the antenna assembly size of the present invention is little,
Lightweight.
2, conventional metal antennas assembly difficulty is relatively big, extremely inconvenient dismounting.The present invention can be with
Time by open water pump erect a television antenna, it is possible to by switching off the pump, pack up flexible pipe and dismantle.
3, antenna uses magnetic core coupled modes preferably to achieve contactless feed and impedance
Coupling；
4, antenna uses metal shell to achieve the shielding to magnet ring interference, and it is right to be simultaneously achieved
The isolation of water；
5, the height of antenna current can be controlled by pump power, and then realizes Antenna Operation frequency
The reconstruct of rate.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.It should be noted that this reality
Execute example to implement under premised on technical solution of the present invention, give detailed embodiment
With concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figures 1 to 3, the present invention is a kind of injection water body antenna, and described antenna includes spray
Injection device 1, coupling toroidal core 2 and R-T unit 3；
Described injection apparatus 1 includes pipeline 11, water pump 12 and nozzle 13, described pipeline
11 are set around on described coupling toroidal core 2, and its one end is connected with described water pump 12, and it is another
One end is connected with described nozzle 13；
Described R-T unit 3 include coaxial line 31, transmitting-receiving radio station 32, described coaxial line 31 around
Being located on described coupling toroidal core 2, its one end is connected with described transmitting-receiving radio station 32.
It should be noted that also include containment vessel 4, described containment vessel 4 is provided with inlet port, row
Outlet and coaxial line connector；Wherein, described coupling toroidal core 2 is arranged at described protection
In shell 4, one end that described pipeline 11 is connected with described water pump 13 stretches out in described inlet port,
The other end stretches out in described outlet, and described coaxial line 31 is connected with described transmitting-receiving radio station 32
One end stretches out in described coaxial line connector.
As the preferred scheme of one, described inlet port, outlet and coaxial line connector set
There is silica gel sheath.
Saying further, sea water or other conductive liquid are pumped to by the water pump 12 of injection apparatus 1
In connected pipeline 11, and after around the pipeline being located on coupling ring shape magnetic core 2,
Shower 10 is formed by nozzle 13 after being sprayed.Transmitting-receiving radio station 32 by coaxial line 31 with
Coupling toroidal core 2 connects, and coaxial line is set around on coupling toroidal core 2 and forms coil.
It should be noted that the coaxial line 31 being set around on described coupling toroidal core 2 is for going
Except sheath and the heart yearn of outer conductor.
As a example by receiving signal, the electromagnetic wave signal in space produces on current through shower
Raw faradic current also flows in the flexible pipe being set around on magnetic core, and the electric current of flexible pipe is formed in magnetic core
Magnetic current, magnetic current produces faradic current on the coil by coaxial inner conductor winding, and this electric current is through same
Axis enters transmitting-receiving radio station and ultimately forms reception signal.
This antenna system is provided without band large-scale metal structure, its lighter in weight.Preferred as one
Scheme, pipe material can use soft pipeline to constitute water stream channel, when needs shift, close
Close the most recoverable sky-line of water pump, roll flexible pipe and can realize rapidly dismounting.
Need it is further noted that resonant frequency and the antenna radiator height correlation of antenna,
Metallic object antenna length is fixed, and resonant frequency is fixed.The present invention can control spray by pump power
Penetrate water-column, and then control antenna resonant frequency, i.e. antenna frequencies reconstruct.
Short-wave antenna input impedance real part is less, by transformator, and last two coils of magnetic core
The number of turns, input impedance can be regulated and realize and the coupling in radio station.
For the bandwidth of the further broadening present invention, another kind of embodiment as shown in Figure 4,
3 groups of pipelines 11, described 3 groups of pipelines it are arranged with on coupling toroidal core 2 in containment vessel 4

And be connected with transmitting-receiving radio station 32.The most on startup, same water pump 12 can control 3 strands of water
Antenna 10, owing to using same water pump 12, therefore it has unified height and water
Pressure, can be described as the sky-line of symmetry, and therefore, the equivalent redius of antenna radiator increases, thus
The beamwidth of antenna obtains broadening.
Another kind of embodiment as shown in Figure 5, its basic with on identical with embodiment, protecting
3 groups of pipelines 11, on the other hand, coaxial line it are arranged with on coupling toroidal core 2 in shell 4
31 are set around on coupling toroidal core 2 and are connected with transmitting-receiving radio station 32, and difference is, 3 groups
Pipeline 11 is respectively provided with independent water pump 12 and controls, the most in use, owing to being independent control
System, can produce the water column 10,20,30 that height is different, and resonance length is different then
Sky-line radiant body combine and constitute broad-band antenna.
For a person skilled in the art, can technical scheme as described above and structure
Think, make other various corresponding changes and deformation, and all these changes and deformation
Within all should belonging to the protection domain of the claims in the present invention.
