Dear all, above shows a modulator (transmitter) and a demodulator (receiver) and the circuit works well. However, this circuit only works if the transmitter and receiver are attached by wire. What modifications should be made to transmit the wave signal wirelessly from the transmitter to receiver? My attempt is I seperated the 2 circuit by building a resonant LC that is the same, hopefully it will resonate together? Is my approach fine?
LT Spice file is attached below for convenience.
Thank you and have a nice day!!
