In this paper, we discuss the heating properties of the proposed hyperthermia system for non-invasive treatment of deep tumors in the abdominal region. Our heating system is composed of a large size resonant cavity applicator. In this heating method, a human body is placed between the two inner electrodes and is heated by electromagnetic fields stimulated in the cavity without contact between the surface of the human body and the applicator. However, the performance of this prototype system was not realized enough because an impedance couldn't be matched sufficiently. We refined the loop type antenna to stimulate electromagnetic fields effectively in the cavity and the experiment was performed with a cylindrical agar phantom. From the experimental heating results, it was found that it is possible to non-invasively heat the deep tumors in the abdominal region without contact with the developed heating system.
