Title (EN) ANTENNA DEVICE AND RADIO COMMUNICATION APPARATUS
(FR) DISPOSITIF D'ANTENNE ET DISPOSITIF DE RADIOCOMMUNICATION
(JA) アンテナ装置および無線通信装置
Abstract:
(EN) An antenna device is provided with: a first coil (L1) and a second coil (L2) which are disposed with the winding axes thereof parallel while being isolated from each other and are magnetically coupled to each other; a first capacitance (C1) which is connected in parallel with the first coil (L1) and constitutes, together with the first coil (L1), a first resonance circuit; a second capacitance (C2) which is connected in parallel with the second coil (L2) and constitutes, together with the second coil (L2), a second resonance circuit; a third capacitance (C3) which is connected between at least one ends of the first coil (L1) and the second coil (L2); and a power feeding terminal (I/O1, I/O2) which is connected to the first coil.
(FR) L'invention concerne un dispositif d'antenne pourvu : d'une première bobine (L1) et d'une deuxième bobine (L2) qui sont disposées avec leurs axes d'enroulement parallèles tout en étant isolées l'une de l'autre et sont couplées magnétiquement l'une à l'autre ; d'un premier condensateur (C1) qui est connecté en parallèle avec la première bobine (L1) et constitue, avec la première bobine (L1), un premier circuit résonant ; d'un deuxième condensateur (C2) qui est connecté en parallèle avec la deuxième bobine (L2) et constitue, avec la deuxième bobine (L2), un deuxième circuit résonant ; d'un troisième condensateur (C3) qui est connecté entre au moins des premières extrémités de la première bobine (L1) et de la deuxième bobine (L2) ; et d'une borne d'alimentation électrique (I/O1, I/O2) qui est connectée à la première bobine.
(JA)  巻回軸がほぼ平行で、互いに絶縁状態に配置され、互いに磁界結合する第1コイル(L1)および第2コイル(L2)と、第1コイル(L1)に並列接続されて、第1コイル(L1)と共に第1共振回路を構成する第1容量(C1)と、第2コイル(L2)に並列接続されて、第2コイル(L2)と共に第2共振回路を構成する第2容量(C2)と、第1コイル(L1)および第2コイル(L2)の少なくとも一方端の間に接続された第3容量(C3)と、第1コイルに接続された給電端子(I/O1,I/O2)と、を備える。
