Title (EN) ANTENNA DEVICE
(FR) DISPOSITIF D'ANTENNE
Abstract:
(EN) An antenna device includes: a plurality of loop metal wires that form loops out of metal wires and that are radially arranged around a center line; a power feeding portion (15) that feeds power to the loop metal wires or a power receiving portion (15) that receives power from the loop metal wires and that is provided on the center line; and a variable impedance element (14) that is inserted in each of the loop metal wires.
(FR) La présente invention concerne un dispositif d'antenne comprenant: une pluralité de câbles métalliques bouclés formant des boucles de câbles métalliques et disposés radialement autour d'une ligne médiane; une partie d'alimentation électrique (15) qui assure l'alimentation électrique des câbles métalliques bouclés ou une partie de réception électrique (15) qui reçoit l'électricité provenant des câbles métalliques bouclés et qui est ménagée sur la ligne médiane; et un élément (14) à impédance variable qui est inséré dans chacun des câbles métalliques bouclés.
