Abstract: Nowadays the use of wireless devices is exceedingly prevalent. These devices do not require physical cables and offer great convenience and productivity in many daily applications such as mobile phones and Ground Positioning System (GPS) devices. The radiations emitted by wireless devices cannot be felt nor seen and will penetrate into human bodies. The study of electromagnetic field radiation effects on human body is important, due to the potential health effects such exposures can cause to humans. This project is focused on studying the radiation effects in human tissues on exposure to electromagnetic fields emitted from a particular antenna. This is a dual band antenna embedded within a wrist wearable Personal Locator Device (PLB). It is capable of transmitting distress signal alerts (Beacons) and receive GPS signals simultaneously. In this project, the antenna has been reproduced using Computer Simulation Technology (CST) and simulations are run to study the radiation effects. To determine if the antenna could be considered safe or not, Specific Absorption Rate (SAR) and temperature increase have been tabulated for different human tissues. The simulation is performed for different parts of the body such as the arm and head in particular. The arm is chosen as the antenna is worn on the wrist primarily while the head is chosen due to its delicateness and significant function in coordinating human body activities. All the simulation runs, calculations, results, findings and conclusions obtained are presented in this report.
