Abstract[English]
ANTENNA DEVICE, TRANSMITTER, AND RADAR Embodiments of the present invention provide an antenna device (10) capable of suppressing unwanted radiation in a center feed. The antenna device (10) includes a dielectric substrate (2) and a conductor pattern (3, 3A, 3B, 3C, 3D, 3E, or 3F) formed on the dielectric substrate (2). The conductor pattern (3, 3A, 3B, 3C, 3D, 3E, or 3F) includes a series antenna array (4). The series antenna array (4) includes a plurality of patch antennas (41, 42, 43, 44, and 45) and a plurality of transmission lines (46, 47, 48, and 49) connecting adjacent patch antennas. The conductor pattern (3, 3A, 3B, 3C, 3D, 3E, or 3F) further includes an input/output line (5) configured to supply power to the series antenna array (4) through a patch antenna (42, 43, or 44) that is not one of patch antennas (41 or 45) at both ends of the series antenna array (4). (FIG. 2)[French]
Des modes de réalisation de la présente invention concernent un dispositif d'antenne (10) qui permet de supprimer un rayonnement indésirable dans une alimentation centrale. Le dispositif d'antenne (10) comprend un substrat diélectrique (2) et un motif conducteur (3, 3A, 3B, 3C, 3D, 3E, ou 3F) formé sur le substrat diélectrique (2). Le motif conducteur (3, 3A, 3B, 3C, 3D, 3E, ou 3F) comprend un réseau d'antennes en série (4). Le réseau d'antennes en série (4) comprend une pluralité d'antennes à plaque (41, 42, 43, 44 et 45) et une pluralité de lignes de transmission (46, 47, 48 et 49) qui connectent les antennes à plaque adjacentes. Le motif conducteur (3, 3A, 3B, 3C, 3D, 3E ou 3F) comprend en outre une ligne d'entrée/sortie (5) configurée pour alimenter le réseau d'antennes en série (4) par l'intermédiaire d'une antenne à plaque (42, 43 ou 44) qui n'est pas l'une des antennes à plaque (41 ou 45) situées aux extrémités du réseau d'antennes en série (4).
