Abstract: By supplying power from the power-supplying resonator to the power-receiving resonator by means of resonance, an electromagnetic space having a relatively low magnetic field strength is formed between the power-supplying resonator and the power-receiving resonator. In so doing, the position where the electromagnetic space is formed is changed by setting the frequency of the AC power supplied from an AC power source to the power-supplying module to an antiphase resonance mode or an inphase resonance mode, and the size of the electromagnetic space is changed by changing the distance between the power-supplying coil and the power-supplying resonator and the distance between the power-receiving resonator and the power-receiving coil.

Abstract: A variable magnetic field in which a power-supplying coil and a power supplying resonator exist is generated only by the power-supplying coil. Power-supplying coils and each of which generates a variable magnetic field due to the supply of a variable current via a first current path on one coil end a side and a second current path on the other coil end side; resonance capacitors which are provided on the first current path and the second current path; and a power-supplying coil short-circuit mechanism which is able to cause at least one of the power-supplying coils and to function as a power supplying resonator by allowing the end portions and of the first current path and the second current path to short-circuit with each other are provided.

Abstract: A wireless power transmission device supplies power by means of a resonance phenomenon, from a power supply module equipped with at least a power-supply resonator to a power-receiving module equipped with at least a power-receiving resonator. For the power-supply resonator and the power-receiving resonator, a value for a transmission characteristic of a power source frequency for power is set so as to have two peak bands, and By setting the power source frequency for the power supplied to the power supply module to the power source frequency band corresponding to one of the two peak bands of the transmission characteristic, magnetic field spaces having a magnetic field strength less than the surrounding magnetic field strength are formed in the area near the power-supply resonator and the power-receiving resonator.

Abstract: First and second conductor layers are formed on a main surface of a base layer. A tapered slot is formed between the first and second conductive layers. A first slit is formed at the first conductor layer, and a second slit is formed at the second conductor layer. Thus, the first conductor layer is divided into a first device connection portion and a first antenna portion, and the second conductor layer is divided into a second device connection portion and a second antenna portion. A semiconductor device is connected to the first and second device connection portions.
