PROBLEM TO BE SOLVED: To provide a flight obstruction device that prevents a small unmanned airplane remotely controlled by radio communication from intruding into a protected region, restrains an impact on communication inside and outside the region, and can reduce the number of necessary antenna devices.SOLUTION: A flight obstruction device obstructs the flight of a small unmanned airplane remotely controlled by radio communication and comprises one or more antenna devices that radiate an interference radio wave from a directional antenna. The directional antenna includes: a radiation element for radiating an interference radio wave in a prescribed frequency band; and a reflector for giving directivity to the radiation direction of the interference radio wave.SELECTED DRAWING: Figure 3
【課題】無線通信により遠隔操縦される小型無人飛行機が保護すべき領域へ侵入することを阻止し、かつ、かかる領域内外の通信への影響を抑え、また、必要とされるアンテナ装置の台数を抑えることができる飛行妨害装置を提供する。【解決手段】無線通信により遠隔操縦される小型無人飛行機の飛行を妨害する飛行妨害装置であって、指向性アンテナから妨害電波を放射する一または複数のアンテナ装置を備え、前記指向性アンテナは、所定の周波数帯の妨害電波を放射する放射素子と、該妨害電波の放射方向に指向性を付与する反射器と、を有することを特徴とする飛行妨害装置により解決する。【選択図】図3
