Capacitive body coupled communication (BCC) channel has been modeled as a two-port complex path impedance matrix [Z] which varies as a function of ten different body positions over the frequency range of 1 MHz to 60 MHz. A systematic numerical simulation methodology has been used to estimate [Z] parameters. The estimated complex path impedance [Z] is a symmetric matrix showing BCC channel is a reciprocal network of passive components for given coupler configuration, body positions and frequency range. The estimated complex path impedance has been utilized to determine either input impedance Zin or output impedance Zout to conjugately match to Zs at transmitter or Zl at receiver, respectively for maximum power transfer. It has been found that the resistive matching below 1000 O and inductive matching between 0.5 ï¿œH to 5 ï¿œH on any side of the two ports can meet the conjugate matching requirements for maximum power transfer for the given body positions and frequency range.
