Abstract
This research involves the investigation of electromagnetic (EM) absorption in the human head using microstrip patch antenna (MPA) and dipole antenna. Both antennas are designed for working in wireless devices at 2.2 GHz. Two parameters are used for the investigation of electromagnetic absorption. These are- peak specific absorption rate (SAR) in the human head tissue and aggregate retained power from the wireless device user. Both antennas are set at a fixed distance to analyze the effects on human head for electromagnetic absorption for MPA and Dipole antenna. The method transmission line (TL) was adopted to find out the parameters of MPA. Both antennas are designed and simulated via CST microwave studio. The outcomes demonstrate that, in human head MPA provides a lower peak SAR value than Dipole antenna. So, total absorbed power of Dipole antenna is higher than MPA. Therefore, MPA is a better option for wireless devices regarding EM absorption reduction.
