Title (EN) ANTENNA DEVICE
(FR) DISPOSITIF D'ANTENNE
(JA) アンテナ装置
Abstract:
(EN) An antenna device is provided with a plurality of antenna elements arranged in a row. The antenna elements located at both ends are each called an end-side antenna element, and the antenna element other than the end-side antenna elements is called an inside antenna element. The end-side antenna element has a structure different from that of the inside antenna element such that a difference in directivity between those used as feed elements among the antenna elements is reduced. Consequently, the estimation accuracy of an arrival direction is improved by a simple method without increasing the amount of calculation.
(FR) L'invention concerne un dispositif d'antenne comportant une pluralité d'éléments d'antenne agencés en rang. Chacun des éléments d'antenne situés au deux extrémités est appelé élément d'antenne côté extrémité, et chacun des éléments d'antenne autres que les éléments d'antenne côté extrémité est appelé élément d'antenne intérieur. L'élément d'antenne côté extrémité présente une structure différente de celle de l'élément d'antenne intérieur de manière à réduire une différence de directivité entre ceux des éléments d'antenne qui sont utilisés comme éléments d'alimentation. Par conséquent, la précision d'estimation d'une direction d'arrivée est améliorée au moyen d'un procédé simple sans augmenter la quantité de calcul.
(JA) アンテナ装置は、一列に配置された複数のアンテナ素子を備える。両端に位置するアンテナ素子を端側アンテナ素子、該端側アンテナ素子以外のアンテナ素子を内側アンテナ素子とする。アンテナ素子のうち給電素子として使用されるもの間の指向性の差が抑制されるように、端側アンテナ素子が内側アンテナ素子とは異なった構造を有する。これにより演算量を増大させることなく簡易な方法で到来方向の推定精度が向上る。
