Abstract
Reflection and mutual interference of electromagnetic signals can be caused in practical applications, thereby resulting in difficulties in realization under strong interference conditions. The utility model provides a fully-shielded honeycomb-shaped antenna array device, aiming to solve the problems of difficulties in positioning frequency modulation launching points of an open-circuit television under strong interference conditions. The device adopts a honeycomb-shaped structure, the walls, the top parts and the bottoms of separated cells adopt aluminum tubes as a frame, and a metal shielding screen is used. Therefore, the weight of the cells can be reduced, the resistance against strong wind can be enhanced, and the interference of open-circuit television signals from other inlets except the inlet on the front face can be isolated. The television frequency modulation signals received by different receiving antennas can be compared under the strong interference conditions so as to judge the directions of the launching points of the different receiving antennas.
Description
Technical field
The utility model relates to the OCTV field of antenna, refers more particularly to a kind of full-shield honeycomb structure array device.
Background technology
In practical application, electromagnetic signal exists reflection, various electromagnetic signal also exists mutual interference.Under this strong jamming condition, realize it being very difficult.
The utility model content
The utility model is under the strong jamming condition, and the directed difficult problem of OCTV frequency modulation transmission point provides a kind of full-shield honeycomb structure array device.The technical scheme that the utility model adopts is:
Antenna assembly adopts honeycomb structure, sees from top to bottom, is divided into 6 open reception antenna cells of coaxial triangle, and the top is arranged up and down, and structure is skeleton with the steel pipe, all covers the metallic shield net.Promptly alleviate deadweight, windproof again, the shielding back is to getting into side direction TV FM signal again;
6 cells altogether, each places 1 secondary high directivity TV FM reception antenna;
The length of walls of cell is 2 times of reception antenna length, prevents that the TV FM signal of sideswipe from getting into;
The full-shield honeycomb structure guarantees that every width of cloth antenna receives only the TV FM signal of the 60 ° of scopes in the place ahead;
The wall of spaced cells and top and bottom are skeleton with the aluminum pipe, adopt the metallic shield web frame, alleviate cell weight like this, strengthen the anti-strong wind performance, can play the effect of the interference of the OCTV signal that completely cuts off non-front entrance direction again;
The TV FM signal power that relatively receives from different reception antennas can be judged its launch point direction.
A kind of full-shield honeycomb structure array device that the utility model provides can realize that the OCTV frequency modulation transmission point is directed under the strong jamming condition.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model.Antenna assembly adopts honeycomb structure, sees from top to bottom, is divided into 6 open reception antenna cells of coaxial triangle, and the top is arranged up and down, and structure is skeleton with the steel pipe, all covers the metallic shield net.Promptly alleviate deadweight, windproof again, the shielding back is to getting into side direction TV FM signal again; 6 cells altogether, each places 1 secondary high directivity TV FM reception antenna; The length of walls of cell is 2 times of reception antenna length, prevents that the TV FM signal of sideswipe from getting into; The wall of spaced cells and top and bottom are skeleton with the aluminum pipe, adopt the metallic shield web frame, alleviate cell weight like this, strengthen the anti-strong wind performance, can play the effect of the interference of the OCTV signal that completely cuts off non-front entrance direction again; The full-shield honeycomb structure guarantees that every width of cloth antenna receives only the TV FM signal of the 60 ° of scopes in the place ahead; The TV FM signal power that relatively receives from different reception antennas can be judged its launch point direction.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
