Title (EN) LUNEBERG LENS ANTENNA DEVICE
(FR) DISPOSITIF ANTENNE À LENTILLE DE LÜNEBERG
(JA) ルネベルグレンズアンテナ装置
Abstract:
(EN) A Luneberg lens antenna device (1) is provided with a Luneberg lens (2) and an array antenna (6). The Luneberg lens (2) is formed in the shape of a circular column obtained by laminating in the radial direction three dielectric layers (3) to (5) having different dielectric constants. The array antenna (6) includes a plurality of patch antennas (7A) to (7C) which are disposed on an outer circumferential surface (2A) side of the Luneberg lens (2) in different focal point locations in the circumferential direction and the axial direction of the Luneberg lens (2). The array antenna (6) is provided over a region in the circumferential direction that is at most equal to half of the total circumference of the Luneberg lens (2).
(FR) Selon l'invention, un dispositif antenne à lentille de Lüneberg (1) comporte une lentille de Lüneberg (2) et une antenne réseau (6). La lentille de Lüneberg (2) est de la forme d'une colonne circulaire obtenue par stratification dans la direction radiale de trois couches diélectriques (3) à (5) ayant des constantes diélectriques différentes. L'antenne réseau (6) comprend une pluralité d'antennes à plaque (7A) à (7C) qui sont disposées du côté d'une surface circonférentielle extérieure (2A) de la lentille de Lüneberg (2) à différents emplacements de foyer dans la direction circonférentielle et dans la direction axiale de la lentille de Lüneberg (2). L'antenne réseau (6) est située sur une région dans la direction circonférentielle qui est au plus égale à la moitié de la circonférence totale de la lentille de Lüneberg (2).
(JA) ルネベルグレンズアンテナ装置(1)は、ルネベルグレンズ(2)と、アレーアンテナ(6)とを備えている。ルネベルグレンズ(2)は、円柱形状に形成され、誘電率の異なる3層の誘電体層(3)~(5)が径方向に積層されている。アレーアンテナ(6)は、ルネベルグレンズ(2)の外周面(2A)側であってルネベルグレンズ(2)の周方向および軸方向の異なる焦点位置に配置された複数のパッチアンテナ(7A)~(7C)を有している。アレーアンテナ(6)は、ルネベルグレンズ(2)のうち全周の1/2以下の周方向範囲に設けられている。
