Wireless IC device and component for wireless IC device
First Claim
1. A wireless IC device comprising:
- a wireless IC chip;
a power supply circuit board connected to the wireless IC chip, and including a power supply circuit including a resonant circuit having a predetermined resonant frequency; and
a radiation pattern, to which the power supply circuit board is adhered or disposed adjacent thereto, arranged to perform at least one of radiation of a transmission signal supplied from the power supply circuit, and receiving a reception signal and supplying the reception signal to the power supply circuit;
whereinthe transmission signal and/or the reception signal have a resonant frequency substantially corresponding to the resonant frequency of the resonant circuit; and
the wireless IC chip is mounted on the power supply circuit board and is provided for the radiation pattern via the power supply circuit board.

Abstract
A wireless IC device includes a wireless IC chip, a power supply circuit board upon which the wireless IC chip is mounted, and in which a power supply circuit is provided, the power supply circuit includes a resonant circuit having a predetermined resonant frequency, and a radiation pattern, which is adhered to the underside of the power supply circuit board, for radiating a transmission signal supplied from the power supply circuit, and for receiving a reception signal to supply this to the power supply circuit. The resonant circuit is an LC resonant circuit including an inductance device and capacitance devices. The power supply circuit board is a multilayer rigid board or a single-layer rigid board, and between the wireless IC chip and the radiation pattern is connected by DC connection, magnetic coupling, or capacitive coupling.
