To provide an antenna system for facilitating narrowband and wideband radio frequency (RF) communication of a rotary-wing aircraft.SOLUTION: A rotor blade 500 is used as a part of an antenna system, where the antenna system includes an RF front-end 505 consisting of RF components 510, 515, 520, and 525 including antenna arrays, RF amplifiers, mixers, waveguides, wires, and frequency tuning mechanisms. By embedding the different types of the RF components into the rotor blade of a rotary-wing aircraft, the number of RF communication links which can be established by the aircraft can be increased significantly.SELECTED DRAWING: Figure 5

    【課題】回転翼航空機の狭帯域および広帯域の無線周波数(RF)通信を容易にするアンテナシステムを提供する。【解決手段】ローターブレード500は、アンテナシステムの一部として使用されており、アンテナシステムは、アンテナアレイ、RF増幅器、ミキサ、導波管、ワイヤおよび周波数チューニング機構を含むRFコンポーネント510、515、520、525からなるRFフロントエンド505を備える。異なる種類のRFコンポーネントを回転翼航空機のローターブレードに埋め込むことにより、航空機が確立しうるRF通信リンクの数を大幅に増加できる。【選択図】図5
