要約
(EN)
An antenna coil, viewed in the direction of the stacking of insulation bodies, is configured at each turn with a first conductor pattern which forms a first side, a second conductor pattern which forms a second side, a third conductor pattern which forms a third side, and a fourth conductor pattern which forms a fourth side. The first conductor pattern is formed in a first layer. The second conductor pattern is formed in a second layer which is different from the first layer. The third and fourth conductor patterns are formed reaching from the first layer to the second layer. The first through fourth conductor patterns are positioned in each insulation layer such that the direction of lines which join the centers of gravity of winding shapes from the conductor patterns of a given turn is inclined with respect to the stacking direction of the insulation layers.

L'invention concerne une bobine d'antenne qui est vue dans la direction d'empilement de corps d'isolation, est configurée à chaque tour avec un premier motif conducteur qui forme un premier côté, un deuxième motif conducteur qui forme un deuxième côté, un troisième motif conducteur qui forme un troisième côté et un quatrième motif conducteur qui forme un quatrième côté. Le premier motif conducteur est formé dans une première couche. Le deuxième motif conducteur est formé dans une seconde couche qui est différente de la première couche. Les troisième et quatrième motifs conducteurs sont formés de sorte à aller de la première couche jusqu'à la seconde couche. Les premier à quatrième motifs conducteurs sont positionnés dans chaque couche d'isolation de telle sorte que la direction des lignes qui rejoignent les centres de gravité des formes d'enroulement des motifs conducteurs d'un tour donné soit inclinée par rapport à la direction d'empilement des couches d'isolation.
