Abstract :
This paper presents a circuit model of the communication channel via magneto quasi-static field for personal area network. To demonstrate the validity of the circuit model, we measured the frequency characteristics of the channel in the range from 100 kHz to 20 MHz. The measured data agree well with the calculated characteristics derived from the circuit model. We also extracted parameters of the model from measured data. The typical loss of the circuit is -62 dB at 10 MHz.
