Abstract
(EN)
An antenna device (101) is provided with: a first coil antenna conductor (L1) having a first end (E1) and a second end (E2); a second coil antenna conductor (L2) having a third end (E3) and a fourth end (E4); and a switching circuit (11). The first coil antenna conductor (L1) is wound around an axis (AX1), and the second coil antenna conductor (L2) is wound around an axis (AX2). The switching circuit (11) switches the first coil antenna conductor (L1) and the second coil antenna conductor (L2) from a connection state including series connection and parallel connection.
(FR)
La présente invention concerne un dispositif d'antenne (101) doté : d'un premier conducteur d'antenne cadre (L1) comprenant une première extrémité (E1) et une deuxième extrémité (E2) ; d'un second conducteur d'antenne cadre (L2) comprenant une troisième extrémité (E3) et une quatrième extrémité (E4) ; et d'un circuit de commutation (11). Le premier conducteur d'antenne cadre (L1) est enroulé autour d'un axe (AX1) et le second conducteur d'antenne cadre (L2) est enroulé autour d'un axe (AX2). Le circuit de commutation (11) commute le premier conducteur d'antenne cadre (L1) et le second conducteur d'antenne cadre (L2) entre des états de connexion en série et de connexion en parallèle.
(JA)
アンテナ装置(101)は、第1端(E1)および第2端(E2)を有する第1コイルアンテナ導体(L1)、第3端(E3)および第4端(E4)を有する第2コイルアンテナ導体(L2)、切替回路(11)を備える。第1コイルアンテナ導体(L1)は軸(AX1)回りに巻回され、第2コイルアンテナ導体(L2)は軸(AX2)回りに巻回されている。切替回路(11)は、第1コイルアンテナ導体(L1)と第2コイルアンテナ導体(L2)とを、直列接続および並列接続を含む接続状態から切り替える。
