Abstract
The characteristics of modern medical radiometers and the types of antennas used in them are considered. The method of accounting for the contribution of individual layers of the multilayer structure of a biological object to the measured brightness temperature is described. A system of rational parameters of antennas used in microwave radiometry has been developed. The paper presents a method for computational modeling of the design parameters of three waveguide antennas of various sizes using the finite-difference time domain (FDTD) method. A set of rational parameters has been developed that confirm the performance of these functions and provide the possibility of optimizing the antenna design when designing multichannel multifrequency medical radiometers.
