Title (EN) MAGNETIC ANTENNA AND ANTENNA DEVICE
(FR) ANTENNE MAGNÉTIQUE ET DISPOSITIF D'ANTENNE
(JA) 磁性体アンテナ及びアンテナ装置
Abstract:
(EN) A magnetic antenna 10 that is provided with: a magnetic core 12 that is configured from a Ni-Zn-Cu-based ferrite sintered body and that has a rectangular parallelepiped shape; and a coil conductor 14 that is wound around the magnetic core 12. The winding axis of the coil conductor 14 is orthogonal to the long direction of the magnetic core 12. The real part of the magnetic permeability of the Ni-Zn-Cu-based ferrite sintered body at 13.56 MHz is 30 or more and the imaginary part is less than 1.
(FR) Une antenne magnétique 10 qui est pourvue : d'un noyau magnétique 12 qui est configuré à partir d'un corps fritté en ferrite à base de Ni-Zn-Cu et qui a une forme de parallélépipède rectangulaire ; et d'un conducteur de bobine 14 qui est enroulé autour du noyau magnétique 12. L'axe d'enroulement du conducteur de bobine 14 est orthogonal à la direction de la longueur du noyau magnétique 12. La partie réelle de la perméabilité magnétique du corps fritté en ferrite à base de Ni-Zn-Cu à 13,56 MHz est supérieure ou égale à 30 et la partie imaginaire est inférieur à 1.
(JA) 磁性体アンテナ10は、Ni-Zn-Cu系フェライト焼結体で構成される、直方体形状を有する磁心12と、磁心12に巻回されるコイル導体14と、を備える。コイル導体14の巻回軸Pは磁心12の長手方向に直交している。Ni-Zn-Cu系フェライト焼結体は、13.56MHzにおける透磁率の実数部が30以上、虚数部が1未満である。
