Antenna for contact microwave radiometers for monitoring of the brain microwave radiation

In the paper, features of the brain microwave radiation measurements are considered. Influence of the contact pins addition on the antenna matching with head surface (changes of the reflection coefficient) is studied. Estimates of human head modelling with contact antenna-applicator are presented. Results of the investigations show that fluctuations of electromagnetic field in the near-field region is defined by magnetic component and depend on functional processes in the human brain.
