Article with an electromagnetic-coupling module

摘要

An article with a feeder circuit board (10) and a wireless IC chip (5) comprises an article, a feeder circuit board (10) and a wireless IC chip (5) attached to the article. The article comprises a radiation plate (20). The feeder circuit board (10) contains a feeder circuit (16) that includes a resonance circuit having a predetermined resonance frequency. The wireless IC chip (5) is electrically connected to the feeder circuit (16). The radiation plate (20) is configured to radiate a transmission signal supplied from the feeder circuit (16) via electromagnetic coupling and/or to supply a received reception signal to the feeder circuit (16) via electromagnetic coupling. The radiation plate is a metal housing (261) of a mobile phone (260).
