| Zusammenfassung: | To provide an antenna device which is simple and small and realizes control of directivity of electric waves.SOLUTION: An antenna device 1 includes: an antenna substrate 10 having an antenna element 10a; a reflector 11 which basically takes a parallel position to the antenna substrate 10; and a rotary mechanism 12 as a variable mechanism which changes an attitude of the reflector 11 in a displacement space S defined in a range formed by projecting a surface of the reflector 11 in the basic position to a direction facing the antenna substrate 10.SELECTED DRAWING: Figure 1A
【課題】簡易かつ小型で電波の指向性制御を実現するアンテナ装置を提供する。【解決手段】アンテナ装置１は、アンテナ素子１０ａを配置したアンテナ基板１０と、アンテナ基板１０に対して平行となる姿勢を基準姿勢とする反射板１１と、アンテナ基板１０は、基準姿勢にあるときの反射板１１の表面をアンテナ基板１０と対向する方向に沿って投影させた範囲で規定される変位空間Ｓ内で、反射板１１の姿勢を変化させる可変機構としての回転機構１２を備える。【選択図】図１Ａ |
