Apparatus and method for wirelessly transmitting and receiving energy and data

A method for wirelessly transmitting energy and data, comprising:

• a signal generation operation of generating a first frequency signal for power transmission;
• a first matching operation of matching input/output impedance upon receiving the first frequency signal generated in the signal generation operation;
• an oscillation operation of outputting a second frequency signal, a carrier frequency, by using the first frequency signal, generated in the signal generation operation, as a reference frequency;
• a modulation operation of modulating a data signal output from a communication module by using the second frequency signal;
• a second matching operation of matching input/output impedance upon receiving the signal modulated by using the second frequency signal;
• a resonation operation of resonating a signal output from the first matching operation to a reception side apparatus;
• and
• a radiation operation of radiating a signal output from the second matching operation to the reception side apparatus.
