Abstract
The article is devoted to determination of electro-physical parameters of mathematical model of antenna connection with the environment of biological object. Principle of change of reflection coefficient near-by an aperture of antenna is used, which is an information about a change of dielectric permeability and temperature of biological environments. Expressions for reflection coefficient, relation of coefficients, conductivity and resistance as functions of many parameters are presented. Analysis of mathematical model « antenna -bioobject» presents the changes of reflection coefficient of radiation from the entrance of antenna, dielectric permeability of environment and conductivity. This method can be used in diagnostics of tumour diseases on the early stages.
