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 phrase 'hyperthermia' refers to several heat treatment procedures used in addition to other therapies. 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 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. 8 In hyperthermia, the frequency that emits wavelengths equal to the size of the tumor in the human body that is of the most significant interest however, government regulation influences the selection of frequency. The Federal Communications Commission in the United States, for Industry, Scientific and Medical (ISM) approve 915MHz and 2.45GHz in Europe, 434MHz were mainly affirmed. 9 In the case of different frequencies, a shielded or secure area should be used to avoid obstructions with a group of communications.įuture research is seeking to use this methodology to overcome some of the inherent limitations of radio frequency medical treatment devices.
