Abstract:
1. A wireless IC device component comprising: a wireless IC; and a coupling electrode including at least one coupling portion arranged to be coupled to the wireless IC directly or via a feed circuit and a pair of ends arranged opposite to each other so as to be capacitively coupled to each other and to define an annular electrode; wherein the coupling electrode is arranged to be coupled to a radiation plate; each of the pair of ends of the coupling electrode includes an inner side and an outer side, the inner side being arranged to be farther from the radiation plate than the outer side; the inner side of one of the pair of ends of the coupling electrode is opposed to the outer side of the other one of the pair of ends of the coupling electrode such that the inner side of the one of the pair of ends of the coupling electrode is capacitively coupled to the outer side of the other one of the pair of ends of the coupling electrode; and the other one of the pair of ends of the coupling electrode is disposed between the one of the pair of ends of the coupling electrode and the radiation plate.
