Electrodynamic calculation of the electric field of a printed ring antenna for microwave radiothermometry of the breast

The results of mathematical modeling of the electric field of a printed ring applicator antenna designed for microwave radiothermometry of breasts are presented. The calculated antenna parameters and radiobrightness temperatures in the projections of malignant tumors were compared for different groups of breasts. The proposed printed ring antenna design is recommended for use in conformal antenna arrays for medical radiothermographs.
