摘要：

Microwave ablation (MWA) has gained appreciation as an alternative to radio frequency ablation in the treatment of tumors. In this paper, COMSOL Multiphysics software is used to perform an analysis of single slot, end capped MWA antenna with a variable geometry fed at a frequency range between 900MHz and 2500MHz, with the purpose of finding configurations that reduce reflections, increase the power transfer to the hepatic tissue and produce faster heating, giving a more efficient antenna design.
