Numerical simulation of miniature antennas applicators of microwave radiometry for diagnostics of the functional state of the brain

Abstract

This paper describes the use of Finite Difference Time Domain technique of numerical modeling for development and simulation symmetrical dipole with triangular shoulders placed in a cylindrical housing and a spiral antenna placed in a cylindrical housing for use in microwave radiometry. The new sensors have been tested and validated on different phantoms and biological tissues. Results suggest sufficient characteristics of broadband antennas for potential use in brain functional diagnostics.
