“…Therefore, one of the main requirements for antennas, in addition to wide-band in the microwave range and miniaturization, is their noise immunity. In [2] the results of modeling of a number of printed antennas are presented, which confirmed the possibility of their use in multichannel radiometers. Currently, the following main types of medical antennas for microwave radiometry are the most widely used: waveguide, printed, vibratory or frame antennas, as well as intracavitary antennas [3][4][5][6].…”

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.
