Specific Absorption Rate Distributions of a Tapered Slot Antenna at 60 GHz in Personal Wireless Devices [Wireless Corner]

Abstract

In the near future, new-generation wireless networks are expected to provide new paradigms over the existing networks with a wide variety of wireless broad-band applications. With this perspective, progress in computational electromagnetics (EM) and advances in utilizing millimeter-wave (mm-wave) frequency bands provide candidates for high-resolution, highspeed broad-band wireless systems/applications. With the advances in wireless technologies and from a publicsafety viewpoint, the biological and health effects induced by mm-waves should be carefully considered before their deployment in the near future. The objective of this study is to analyze the specific absorption rate (SAR) of an antipodal linear tapered slot antenna (ALTSA) operating at 60 GHz utilizing substrate integrated waveguide (SIW) technology for personal wireless devices (PWDs). For a better understanding of the interactions between the human body and antennas for wireless devices like laptops and headphones, SAR at the head and anterior thigh positions and temperature rises have been characterized numerically and computationally using EM simulation tools with phantom models.
