<p>This near-field communication antenna module allows freely selecting security and applications by switching the SD or SIM having a near-field communication function based on a multi-directional magnetic field. This near-field communication antenna module is provided with an FPC and a magnetic plate (6) on the side opposite of the surface where a contact terminal (CT) of the SIM (11) or SD (7) is disposed. On said magnetic plate (6), there is an antenna unit (8) comprising a planar loop coil antenna (4) and a wound-around coil antenna (5) forming a tight coupling overlapping one side of said coil antenna (4) which are wound orthogonally to each other, the antenna unit (8) being configured such that the resulting magnetic field (H) is radiated two- or three-dimensionally. On the surface of the substrate (FPC) where the magnetic plate (6) is present, an IC circuit unit (9) is provided which comprises an application IC chip, a security IC chip, a near-field communication IC chip, an analogue IC chip and an interface IC chip, and the antenna unit (8) and the IC circuit unit (9) are integrated into a module.</p> |
