Abstract: A resonant circuit and an antenna device achieve a low resonance frequency without increasing a coil size, and improve communication performance. In the resonant circuit, two coil-shaped conductors are arranged so as to be opposed to each other with a dielectric sheet interposed therebetween. The two coil-shaped conductors are, at the opposed portions thereof, coupled with a capacitance interposed therebetween, and wound so that electric currents flowing through the respective conductors trend in the same direction in a planar view. The opposed area in at least a portion of the outermost windings and/or innermost windings of the coil-shaped conductors is larger as compared with the opposed area in any other winding, and the respective ends of the conductors define power feeding units.

Abstract: A short-range wireless communication device includes a coil, a capacitor, a short-range wireless communication IC, and a rectifier circuit. The short-range wireless communication IC and the rectifier circuit are connected to the coil via a node. The capacitor is connected between the node and the rectifier circuit. A receiving circuit is composed of the coil and a power-receiving circuit is composed of the coil and the capacitor. An output impedance of the receiving circuit is set larger than an output impedance of the power-receiving circuit at a communication frequency, and the output impedance of the power-receiving circuit is set smaller than the output impedance of the receiving circuit at a power-receiving frequency, by appropriately setting capacitance of the capacitor.
