Hyperthermia is an alternative procedure for cancer treatment. It has potential either used alone or adjuvant with other conventional procedures such as chemotherapy and radiotherapy to enhance the capability of chemotherapy drugs and the radiation intensity, respectively. However, since the success rate is still not significant, the requirements in improving the limitations for this alternative procedure are massively carried out. Therefore, in this paper, it is emphasised to improve the main deficiency of this hyperthermia treatment, which is focus position distance in order to reduce the possible adverse health effects due to the treatment by reducing the area of unwanted hot spots on surrounding healthy tissue. A simulation with SEMCAD X is utilised to obtain heat distribution on the treated tissue. Various rectangular microstrip-slot applicators have been modified and developed with SEMCAD X, where it is used to provide heat towards the treated tissue at a certain period of time and hyperthermia specific temperature. The outcomes showed the modified microstrip-slot with a Y shape is able to penetrate up to 80 mm with sufficient focus position distance. Finally, a water bolus is introduced to produce a cooling impact on the treated tissue, which also alters the effective field size (EFS) of heat dispersion.
