Abstract: An RFID device provided at a transmission and reception circuit processes an RFID carrier signal belonging to a band of about 902 MHz to about 928 MHz or about 865 MHz to about 868 MHz to execute near field radio communication. An RFIC provided at a transmission and reception circuit processes a GSM carrier signal belonging to a band of about 824 MHz to about 894 MHz or about 880 MHz to about 960 MHz to execute mobile communication. A filter circuit provided at the transmission and reception circuit takes the band of about 850 MHz to about 940 MHz where RFID carrier signals appear as the pass band, and takes the band greater than or equal to about 1.2 GHz where a harmonic wave component of GSM carrier signals appears as the attenuation band.

Abstract: A wireless IC device includes a wireless IC chip, a coupling electrode, and a radiation plate. The coupling electrode includes coupling portions arranged to be coupled to the wireless IC chip and a pair of opposing ends. The pair of opposing ends are capacitively coupled to each other and oppose the radiation plate to be coupled to the radiation plate. The wireless IC chip uses the radiation plate as an antenna to transmit and receive signals having certain frequencies to and from an RFID system.
