Abstract
An RFID auxiliary antenna device is provided on an article that is adjacent to an RFID tag to be communicated or accommodates the RFID tag. The RFID auxiliary antenna device includes a conductive pattern that circles the article. A capacitance component generated between conductive patterns and an inductance component of the conductive pattern configure a resonant circuit. A resonant frequency of the resonant circuit is equal to or substantially equal to a communication frequency of the RFID tag, and the RFID auxiliary antenna device is magnetically coupled to each of the RFID tag and a reader/writer.
