Abstract[English]
ANTENNA DEVICE, TRANSMITTER, AND RADAR Various apparatus for providing an antenna device capable of achieving wide bandwidth are disclosed. The antenna device includes a dielectric substrate and a conductor pattern formed on the dielectric substrate. Herein, the conductor pattern includes an antenna array including a plurality of patch antennas connected in series, an input/output line feeding the antenna array, and a junction. The junction is interposed between the input/output line and a first patch antenna from the plurality of patch antennas located at an end of the antenna array connected to the input/output line. The junction is narrower than the first patch antenna and wider than a transmission line connecting adjacent patch antennas in the antenna array. (FIG. 2)[French]
L'invention concerne un dispositif d'antenne, un émetteur et un radar, ainsi que divers appareils destinés à fournir un dispositif d'antenne capable d'obtenir une large bande passante. Le dispositif d'antenne comprend un substrat diélectrique et un motif conducteur formé sur le substrat diélectrique. Le motif conducteur comprend un réseau d'antennes comprenant une pluralité d'antennes à plaque connectées en série, une ligne d'entrée/sortie alimentant le réseau d'antennes, et une jonction. La jonction est interposée entre la ligne d'entrée/sortie et une première antenne à plaque à partir de la pluralité d'antennes à plaque situées à une extrémité du réseau d'antennes connectée à la ligne d'entrée/sortie. La jonction est plus étroite que la première antenne à plaque et plus large qu'une ligne de transmission connectant des antennes à plaque adjacentes dans le réseau d'antennes. (FIG. 2)
