Title (EN) ANTENNA DEVICE AND ELECTRONIC APPARATUS
(FR) DISPOSITIF D'ANTENNE ET APPAREIL ÉLECTRONIQUE
(JA) アンテナ装置および電子機器
Abstract:
(EN) An antenna device (10) is provided with: a coil antenna (11) of a first non-contact transmission system; and a coil antenna (12) of a second non-contact transmission system. The coil antenna (11) has a coil (13). The coil antenna (12) has: a coil (14) to be coupled to the coil (13); and a coil (15) to be coupled to the coil (14) in the direction in which mutual inductance is improved. When the coupling between the coil (13) and the coil (14) is defined as coupling in the positive direction, the coil (15) is coupled to the coil (13) in the negative direction, and has a shape asymmetric to the coil (14).
(FR) La présente invention concerne un dispositif d'antenne (10) qui est pourvu : d'une antenne à cadre (11) d'un premier système de transmission sans contact ; et d'une antenne à cadre (12) d'un second système de transmission sans contact. L'antenne à cadre (11) comporte une bobine (13). L'antenne à cadre (12) comporte : une bobine (14) qui doit être couplée à la bobine (13) ; et une bobine (15) qui doit être couplée à la bobine (14) dans la direction dans laquelle une inductance mutuelle est améliorée. Lorsque le couplage entre la bobine (13) et la bobine (14) est défini comme étant un couplage dans la direction positive, la bobine (15) est couplée à la bobine (13) dans la direction négative et présente une forme asymétrique par rapport à la bobine (14).
(JA) アンテナ装置(10)は、第1非接触伝送システムのコイルアンテナ(11)および第2非接触伝送システムのコイルアンテナ(12)を備える。コイルアンテナ(11)はコイル(13)を有する。コイルアンテナ(12)は、コイル(13)に結合するコイル(14)と、コイル(14)と互いのインダクタンスを高める方向に結合するコイル(15)とを有する。コイル(15)は、コイル(13)とコイル(14)との結合を正方向の結合と定義したときに、コイル(13)と負方向に結合し、かつ、コイル(14)と非対称な形状を有する。
