WIPO Patent Application WO/2014/125927
Kind Code:
A1
Abstract:
An antenna device (101) provided with a metal plate (surface conductor) (2), and an antenna coil (3). The main components of the antenna coil (3) comprise an insulating base material (33), and a coil conductor (31) formed on the base material (33). The metal plate (2) has a first conductor opening part (21), and a second conductor opening part (22). The second conductor opening part (22) is connected to the first conductor opening part (21), and is not connected to the outer edge of the metal plate (2). With respect to the antenna device thus provided with the coil conductor and the surface conductor, which opposes a coil opening of the coil conductor, the problem of electromagnetic shielding by the surface conductor is eliminated.
