Outline of Final Research Achievements

The transmitting and receiving antennas for communication systems using a linearly polarized wave need polarization alignment (PA). On the other hand, those using a circularly polarized (CP) wave do not need the PA. Although CP antennas have such an advantage, there are little data on a CP reconfigurable antenna, which reproduces the same antenna characteristics during the beam steering. In this context, this research presents a realization of the CP reconfigurable antenna, where metaatoms are used. A systematic investigation on the radiation characteristics is performed on the basis of electromagnetics.

Academic Significance and Societal Importance of the Research Achievements

メタアトムを使用して実現した本アンテナの放射パターン,入力インピーダンス,および利得は,ビーム方向が変わってもそのつど同じものとなる.つまり,ビーム走査時に固有の特性が再現される,という特長を有する.従って,この「円偏波放射ビーム走査・特性再生可能アンテナ」は,動きの激しい移動体と基地局との通信に対して有効であり,高度情報化社会に貢献する.
