Wireless communication is one of the most popular forms of communication which basic principle to interchange electromagnetic energy through the antenna. This communication technology is surely helpful for us but the drawbacks are also harmful for us. Wireless communication technology causes a serious electromagnetic radiation towards mankind when using mobile phone. The antenna radiates EM waves and our head tissue absorbs this radiation. It produces heat in our brain tissue which causes biological disorder. So, an adequate study is necessary to lessen this radiation and its damages. SAR values have to measure to quantify the effect of the human brain. In this research, SAR value has been investigated for three types of head phantoms and they are a healthy adult human head, a head phantom with a tumor and a child head phantom. We measure the value from different distance and different position of the antenna from human head phantom.
