In hyperthermia treatment for cancer, the antenna used as hyperthermia applicator needs to be designed carefully in order to heat the cancer cell without affecting the healthy cell. Unfortunately, as different antenna design produces different radiation pattern, it will lead to different heating distribution values. With these values, the time duration of the exposure for the cancer cell will also be different. In this research, the capability of a dipole antenna as hyperthermia applicator has been analyzed. The analysis has been done using simulation model in CST microwave simulation software based on FDTD technique. The result shows that the dipole antenna is deemed to be used as hyperthermia applicator. The heating pattern from the dipole antenna based on SAR distribution pattern shows that the focus area of the human tissues model, that has been designed using water bolus model has high Specific Absorption Rate (SAR) value compare to the surrounding area.
