Numerical study of hyperthermia was performed using a microwave slot antenna in the treatment of liver cancer. The modeling of the problem in Comsol software is done symmetrically and two-dimensionally and the electromagnetic equation is coupled with the biothermal transfer equation. Temperature distribution, cancer tissue destruction, microwave absorption in liver tissue and specific absorption rate (SAR) are presented as results. The results showed that the two-hole antenna has a wider distribution of the amount of microwave absorbed than the single-slot antenna. The SAR distribution along the longitudinal axis of the antennas gradually increases and reaches its maximum point where the slot is located, and then the SAR distribution decreases rapidly and reaches its minimum at the end of the antenna. According to the results, changes in temperature in liver tissue also depend on the type of antenna and penetration depth, and temperature distribution and SAR distribution have a similar trend. Also, single-slot antenna is suitable for elliptical tumors and double-slot antenna is suitable for spherical tumors.
