ARTICLE PROVIDED WITH ELECTROMAGNETICALLY COUPLED MODULE

摘要

Provided is an article having an electromagnetically coupled module, which has a built-in wireless IC chip and stable frequency characteristics. An electromagnetically coupled module (1a) is composed of a wireless IC chip (5), and a feed circuit board (10), which has the wireless IC chip (5) mounted thereon and a feed circuit (16) including a resonance circuit having a prescribed resonance frequency. The electromagnetically coupled module is mounted on an article. The article is provided with a radiation plate (20), which radiates a transmission signal supplied from the feed circuit (16) of the electromagnetically coupled module (1a) through electromagnetic coupling and supplies the received signal to the feed circuit (16) through electromagnetic coupling.
