摘要： A power and data receiver according to the present embodiment includes: a reception coil configured to receive a power data signal from a transmission coil; a power unit forming driving power from the power data signal; and a data demodulation unit configured to demodulate a data signal from the power data signal, wherein the reception coil operates adjacent to the transmission coil to the extent that a first resonant frequency and a second resonant frequency are formed between the reception coil and the transmission coil, and the reception coil operates at a frequency greater than or equal to the first resonant frequency and smaller than or equal to the second resonant frequency in relation to the transmission coil.
