FOLDED NEAR FIELD COMMUNICATION ANTENNA

摘要

Provided is an antenna structure which is capable of having sufficient antenna performance even in an antenna having a small cross-sectional area. The antenna of the present invention comprises: a ferrite sheet; and an antenna sheet (flexible printed circuit board) which has a spiral loop antenna pattern. The antenna sheet is folded and the ferrite sheet is inserted therein to form a folded antenna. The folded antenna is configured in such a manner that a longitudinal pattern of the spiral loop antenna pattern is disposed close to a longitudinal centerline portion of the ferrite sheet.
