Title (EN) ANTENNA DEVICE AND COMMUNICATION DEVICE
(FR) DISPOSITIF D'ANTENNE ET DISPOSITIF DE COMMUNICATION
(JA) アンテナ装置および通信装置
Abstract:
(EN) In terms of outward appearance, an antenna device (111) is, for example, the jacket of a communication terminal (100). The communication terminal (100) is a portable terminal, for example, and a communication device (201) is configured by mounting the antenna device (111) on the communication terminal (100). The antenna device (111) is an antenna device that uses HF-band high-frequency signals as a carrier frequency, and is configured as an antenna device for a reader-writer used in a close-range communication system. The antenna device (111) has a resinous plate-shaped base as a body. An antenna coil (20) and an electric power supply coil (30) are integrally provided to the plate-shaped base. High-frequency signals are transmitted without contact between the electric power supply coil (30) and the antenna coil (20) via magnetic coupling.
(FR) Selon l'invention, du point de vue de son aspect extérieur, un dispositif d'antenne (111) est, par exemple, l'habillage d'un terminal de communication (100). Le terminal de communication (100) est un terminal portatif, par exemple, et un dispositif de communication (201) est configuré en montant le dispositif d'antenne (111) sur le terminal de communication (100). Le dispositif d'antenne (111), qui est un dispositif d'antenne qui utilise des signaux à haute fréquence dans la bande HF comme fréquence porteuse, est configuré sous la forme d'un dispositif d'antenne pour un appareil de lecture-écriture qui est utilisé dans un système de communication à courte portée. Le dispositif d'antenne (111) possède comme corps une base en forme de plaque de résine. Une bobine d'antenne (20) et une bobine d'alimentation électrique (30) sont intégrées dans la base en forme de plaque. Des signaux à haute fréquence sont transmis sans contact entre la bobine d'alimentation électrique (30) et la bobine d'antenne (20), par un couplage magnétique.
(JA)  アンテナ装置(111)は例えば外観上は通信端末(100)のジャケットである。通信端末(100)は例えば携帯端末であり、通信端末(100)にアンテナ装置(111)が装着されることにより通信装置(201)が構成される。アンテナ装置(111)は、HF帯の高周波信号をキャリア周波数とするアンテナ装置であり、近距離通信システムに用いられるリーダライタ用のアンテナ装置として構成されている。アンテナ装置(111)は、樹脂製の板状基材を素体としている。板状基材には、アンテナコイル(20)と給電コイル(30)とが一体的に設けられている。給電コイル(30)とアンテナコイル(20)とは磁界結合を介し、非接触で高周波信号が伝達される。
