Abstract: An object is to improve the communication quality in a system for wirelessly transmitting electric power and data. A transmission module is used as a power transmitting module or a power receiving module in a wireless power data transmission device for wirelessly transferring electric power and data between the power transmitting module and the power receiving module. The transmission module includes: a coil for transmitting or receiving electric power through magnetic field coupling; a communication electrode for transmitting or receiving signals through electric field coupling; a first conductive shield that is located between the coil and the communication electrode; and a second conductive shield that is located between the coil and the first conductive shield.

Abstract: In a system for wirelessly transmitting electric power and data, communication quality is improved. A transfer module is for use as a power transmitting module or a power receiving module in a wireless power/data transfer apparatus that wirelessly transmits electric power and data between a power transmitting module and a power receiving module. The transfer module includes: an antenna that performs power transmission or power reception via magnetic field coupling or electric field coupling; a differential transmission line pair to perform transmission or reception via electric field coupling; and a shielding part being located between the antenna and the differential transmission line pair to reduce electromagnetic interference between the antenna and the differential transmission line pair.

Abstract: A wireless power and data transmission apparatus includes an inner module and an outer module. The inner module includes: an annular-shaped first antenna disposed around an axis; and an annular-shaped first communication electrode disposed around the axis, the first communication electrode being at a different position from that of the first antenna regarding a direction along the axis. The outer module includes: an annular-shaped second antenna disposed around the axis, the second antenna performing power transmission or power reception with the first antenna via magnetic field coupling or electric field coupling; and an annular-shaped second communication electrode disposed around the axis, the second communication electrode being at a different position from that of the second antenna regarding the direction along the axis, and the second antenna performing communications with the first communication electrode via electric field coupling.
