Flight interference apparatus

A flight interference apparatus that interferes with flight of a miniature unmanned aerial vehicle which is remotely piloted by radio communication,

• wherein the flight interference apparatus comprises one or a plurality of antenna devices which radiate a jamming signal from a directional antenna,
• the directional antenna includes a radiating element which radiates a jamming signal of a predetermined frequency band and a reflector which gives directionality to the jamming signal in its radiation direction,
• the directional antenna includes a plurality of the radiating elements for the one reflector, and
• the plurality of the radiating elements radiate jamming signals of different frequency bands respectively.

• the directional antenna includes a radiating element which radiates a jamming signal of a predetermined frequency band and a reflector which gives directionality to the jamming signal in its radiation direction,
• each of the antenna devices is deployed close to the boundaries of a geographical area or space where intrusion by the miniature unmanned aerial vehicle should be blocked, and
• for the directional antenna of each of the antenna devices, its elevation angle and azimuth angle are set to an angle so that the jamming signals will radiate toward intrusion paths into the geographical area or space and the jamming signals will have less influence on the geographical area or space.
