The temperature of the hyperthermia treatment varies from 40 oC to 48 oC, and the heat temperature retained at the treatment area for one hour or more. 1–4 These techniques provide high temperatures, 5–8 potentially causes direct damage to cancer cells compared to chemotherapy treatment with minimal or no harm to normal tissues and therefore this technique applied as an anti-drug for cancer treatment. The phrase 'hyperthermia' refers to several heat treatment procedures used in addition to other therapies. Keywords : hyperthermia, dipole antenna, SAR, FDTD technique, CST microwave studio IntroductionĪs cancer treatment technique, hyperthermia employs an outside, warm source to increase tissue temperature and slaughter cancer cells or impede their advance growth.
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. The result shows that the dipole antenna is deemed to be used as hyperthermia applicator. The analysis has been done using simulation model in CST microwave simulation software based on FDTD technique. In this research, the capability of a dipole antenna as hyperthermia applicator has been analyzed. With these values, the time duration of the exposure for the cancer cell will also be different. Unfortunately, as different antenna design produces different radiation pattern, it will lead to different heating distribution values.
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.
