Abstract

A packaging material with an electromagnetic coupling module for a RFID system, is constructed such that a radio IC chip is protected from external shock and environmental change without adversely affecting the planarity of the packaging material, the assembly of a radiator and an electromagnetic coupling module is facilitated, and the radiation characteristics are satisfactory. A packaging material includes a liner and a wave-shaped core material, wherein an electromagnetic coupling module and a radiator that are electromagnetically coupled to each other are arranged inside of the packaging material. The electromagnetic coupling module includes a radio IC chip and a feeder circuit board, on which the radio IC chip is mounted, the feeder circuit board including a resonant circuit that includes an inductance element. The radiator electromagnetically couples with the electromagnetic coupling module to transmit/receive high frequency signals.
