| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an antenna device that can generate a radiation pattern with null reduced although setting of amplitude of high frequencies transmitted or received by each antenna element of an array antenna is simple.SOLUTION: An antenna device 10 has one end 10a and another end 10b, and includes an array antenna 20 in which a plurality of antenna elements 30 are arranged at a constant interval d from the one end 10a to the other end 10b, and transmits or receives high frequencies by changing amplitude at a constant rate from an antenna element 30 at the one end 10a to an antenna element 30 at the other end 10b.SELECTED DRAWING: Figure 2
【課題】アレーアンテナの各アンテナ素子が送信又は受信する高周波の振幅の設定が単純でありながら、ヌルを低減した放射パターンを実現できるアンテナ装置を提供する。【解決手段】アンテナ装置１０は、一端１０ａ及び他端１０ｂを有し、一端１０ａから他端１０ｂにかけて複数のアンテナ素子３０が一定の間隔ｄで配置されたアレーアンテナ２０を備え、一端１０ａのアンテナ素子３０から他端１０ｂのアンテナ素子３０にかけて一定の割合で振幅を異ならせて高周波を送信又は受信する。【選択図】図２ |
