摘要： A wireless power receiver device includes a sheet-like electrode sheet section and a power receiver section. The electrode sheet section includes a power receiver side active electrode and a power receiver side passive electrode that are substantially coplanar and formed into sheet-like shapes; lead lines that are coplanar with both the electrodes, extended from the respective electrodes, and formed into sheet-like shapes; and an insulation sheet that covers both the electrodes and both the lead lines from both sides thereof. The power receiver section includes a step-down unit that steps down an alternating-current voltage induced between end portions of the lead lines; a power receiver module that rectifies and smoothes the alternating-current voltage that is stepped down by the step-down unit; and a connector for outputting an output voltage of the power receiver module.

摘要： An antenna device includes an antenna element and an impedance conversion circuit connected to the antenna element. The impedance conversion circuit is inserted between the antenna element and a feeding circuit, and includes a first series circuit where a first coil conductor and a second coil conductor are connected in series, and a second series circuit where a third coil conductor and a fourth coil conductor are connected in series. The first and second coil conductors define a closed magnetic circuit through which a closed loop of a first magnetic flux passes, and the third and fourth coil conductors define a closed magnetic circuit through which a closed loop of a second magnetic flux passes. Consequently, the antenna device performs impedance matching with the feeding circuit in a wide frequency band.
