ANTENNA STRUCTURE, COMMUNICATION APPARATUS, AND METHOD OF MANUFACTURING ANTENNA STRUCTURE

摘要

Provided is an antenna structure which can be incorporated by utilizing the space of a communication apparatus efficiently and exhibits good characteristics while reducing the cost.  An antenna coil (11) which is incorporated in a cellular phone (200) and coupled inductively with a reader/writer (2) generating a magnetic field to thereby become communicable is formed by winding a flat cable (111), which is produced by coating one flat type wire (301) with an insulator (302), around the side surface (202a) of the charging portion (202) of a secondary battery incorporated in a cellular phone (200), while bonding the flat cable with insulating adhesive (112).
