Specific embodiment
It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood
The application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, not
For limiting the application.
Omni-directional antenna arrays provided by the present application can be, but not limited to be applied in Image transmission equipment and video monitoring etc.
In system.
In one embodiment, with reference to Fig. 1, a kind of omni-directional antenna arrays, including several dipoles vibration member 100, feedback are provided
Electric wire 200 and several baluns 300.Here several refer to two or more.Several dipole vibration members 100 are electrically connected
It is connected to feed line 200, and then forms series feed structure.
With reference to Fig. 2 and Fig. 3, each dipole vibration member 100 includes the first oscillator 110 interconnected and the second oscillator
120.The first oscillator 110 and the second oscillator 120 of same dipole vibration member 100 are about 200 axial symmetry of feed line.Dipole vibration member
100 directional diagram itself has omni-directional, by the way that several dipoles vibration member 100 is formed array, and then high increasing may be implemented
Benefit.
In addition, the present embodiment omni-directional antenna arrays are additionally provided with several baluns 300 with reference to Fig. 1.Balun 300 and dipole shake
Member 100 is also arranged in a one-to-one correspondence.And the balun 300 of the present embodiment is sleeve-shaped, and is arranged and covers respective dipole vibration
The part-structure of at least partly structure of member 100 and the feed line being connect with respective dipole vibration member 100.Therefore, the application
Balun 300 can be realized dipole vibration member 100 and feed line 200 and between balance and non-balance conversion.
Meanwhile balun 300 is arranged and covers at least partly structure of respective dipole vibration member 100, so that balun 300 can be with
Energy is obtained by way of coupling with dipole vibration member 100, first 100 knots so that 300 structure of balun and dipole shake
Structure can one new resonance of equivalent formation.
Since the overall size of 300 structure of balun and first 100 structures of dipole vibration is greater than the ruler of first 100 structures of dipole vibration
It is very little, therefore the new resonance has longer wavelength, i.e. the new resonance has lower frequency.More low-frequency new resonance
It is superimposed effectively to expand bandwidth with the resonance of dipole vibration member 100 itself.
