Abstract
The utility model discloses a wireless radio wave directional interference shade which comprises an interference source and an emitter connected with the interference source, wherein a shade body is connected at the front end of the interference source, the emitter is arranged in the shade body, and an opening is arranged at the front end of the shade body. The wireless radio wave directional interference shade is simple in structure, performs wireless interference within an appointed range and reduces the influence on communication of other places caused by the interference source.
Description
Technical field
The utility model relates to a kind of directional jamming cover, particularly a kind of radio wave directional jamming cover.
Background technology
Radio interference is meant and takes place in the radio communication process, causes that the useful signal quality of reception descends, infringement or the state and the fact that hinder.Existing radio interference all is an omnidirectional, that is to say it is direction-free, and the zone of not only needs being disturbed, other local communications around also having influence on greatly.
The utility model content
The technical problem that the utility model will solve provide a kind of simple in structure, in the scope of appointment, carry out air interference, reduce interference source to around the radio wave directional jamming cover of other local communications influence.
For solving this technical problem, the concrete scheme of the utility model is:
A kind of radio wave directional jamming cover comprises interference source and the reflector that is connected with interference source, and said interference source front end is connected with cover body, and said reflector places cover body inner, and the cover body front end is provided with opening.
Further, said opening is a trapezoid-shaped openings.
Further, said reflector is an antenna.
Further, said cover body is a metal cap.
Adopt the radio wave directional jamming cover of technique scheme; Because said interference source front end is connected with cover body; Reflector places cover body inner, and the cover body front end is provided with opening, so can play the effect of radio wave directional jamming well; And strengthened the interference effect in the predetermined interference region, not needing to have avoided the Communication Jamming influence of interference region well.
Description of drawings
Fig. 1 is the structural representation of the utility model radio wave directional jamming cover.
Embodiment
As shown in Figure 1, a kind of radio wave directional jamming cover comprises interference source 1 and the reflector 3 that is connected with interference source 1; Interference source 1 front end is connected with cover body 2, and reflector 3 places cover body 2 inside, and cover body 2 front ends are provided with opening 4; Opening 4 is a trapezoid-shaped openings, and reflector 3 is an antenna, and cover body 2 is a metal cap.
The opening 4 of the said cover body 2 of the utility model is oriented the appointed area; Make the air interference signal launch towards the appointed area; And the interference electric wave of emission on other directions shielded by cover body 2, and reflexes to the appointed area, thereby strengthens the interference effect in the appointed area.The extension coca of the size of opening 4 and cover body 2 is border situation and deciding factually, can artificially control so disturb the zone.
The utility model has played the effect of radio wave directional jamming.Especially in important examination hall or meeting room, make the mobile phone signal radio interference.
