Investigation of the Electromagnetic Dosimetry Characteristics of a 4 × 4 MIMO Antenna for WLAN Applications

Abstract

With the development of new generation communication systems, antenna technologies used in these areas and their effects on human health are also examined. In this study, a 4×4 MIMO antenna was designed for IEEE 802.11a applications through the finite element method (FEM) based electromagnetic simulation software. Also, its dosimetric effects on tissue were investigated. The proposed antenna includes four antennas operating at 5 GHz. It was designed on a 74 mm ×130 mm dielectric material with a frame height of 5 mm to meet the trend of current phones. The SAR distribution in the head and hand model caused by the antenna model were obtained as 1.4 W/kg and 0.7 W/kg for 1 gr average tissue, respectively.
