Transmission and Reception with Embedded Antennas

Electromagnetic problems relating to biomedical telemetry are reviewed. The reciprocal theorem is used with the previously determined receiving properties of embedded bare and insulated dipoles and two-element arrays to obtain the ratio of the voltage across the load in a receiving dipole or Yagi array in air to the voltages driving various embedded transmitting antennas. The solution of the electro-magnetic problem of the transponder at vrious depths in a body of skin is thus completed.
