Abstract
(EN)
The antenna of the present invention is provided with a conductive-wire-wound hollow-core coil, a relay member connected to the coil, and a plate-shaped magnetic member for covering some of the relay member and the coil. The relay member is provided with a substrate having a cutout part through which a lead of the coil is passed, and a pair of terminal members formed on the substrate. Each of the terminal members has an inside terminal part connected to an end part of the lead, an outside terminal part to which an external circuit is connected, and a path part where the inside terminal part and the outside terminal part are connected. One part of the coil and relay member, stacked on the magnetic substrate, is fixed to a first adhering layer provided on a non-transmitting surface side of the coil. The inside terminal part is formed in a region overlapping the magnetic member, or in a region surrounded by the cutout part of the magnetic member.

La présente invention concerne une antenne comprenant une bobine à noyau creux entourée d'un fil conducteur, un élément relais connecté à la bobine et un élément magnétique en forme de plaque destiné à recouvrir une partie de l'élément relais et de la bobine. L'élément relais comprend un substrat comportant une partie découpée au travers de laquelle passe un fil de la bobine et une paire d'éléments de bornes formés sur le substrat. Chacun des éléments de borne comprend une partie de borne intérieure connectée à une extrémité du fil, une partie de borne extérieure à laquelle est connecté un circuit extérieur et une partie de trajet par laquelle sont connectées la partie de borne intérieure et la partie de borne extérieure. Une partie de la bobine et de l'élément relais, empilés sur le substrat magnétique, est fixée sur une première couche adhésive placée sur un côté de surface non émettrice de la bobine. La partie de borne intérieure est formée dans une région qui se superpose à l'élément magnétique ou dans une région entourée par la partie découpée de l'élément magnétique.
