Container with electromagnetic coupling module
First Claim
1. A container comprising:
- an electromagnetic coupling module including a radio IC chip and a feeder circuit board on which the radio IC chip is mounted, the feeder circuit board including a feeder circuit including a resonant circuit that includes an inductance element and has a predetermined resonant frequency; and
a radiator that is electromagnetically coupled to the inductance element of the feeder circuit board;
whereinthe feeder circuit board is defined by a multilayer board and the resonant circuit of the feeder circuit is disposed within the multilayer board;
the electromagnetic coupling module is attached to an inner surface of the container;
the radiator is attached to an outer surface of the container, and the radiator is arranged to radiate a transmission signal supplied from the resonant circuit through electromagnetic coupling and/or to supply a reception signal to the resonant circuit through electromagnetic coupling.

Abstract
A container includes an electromagnetic coupling module on an inner surface of a container main body and a radiator made of a metal material on an outer surface of the container main body. The electromagnetic coupling module includes a feeder circuit board, on which a radio IC chip is mounted and in which a feeder circuit including a resonant circuit that has a predetermined resonant frequency and includes an inductance element is provided. The electromagnetic coupling module and the radiator preferably transmit and receive high-frequency signals through electromagnetic coupling. The container thus has an electromagnetic coupling module that includes a radio IC chip that is resistant to a shock applied from the outside and an environmental change, realizes an easy arrangement of a radiator and the electromagnetic coupling module, provides a preferable radiation characteristic, and is suitably used in an RFID system.
