The Influence of Human Tissues on the Patch Antennas' Parameters

Authors/Creators

Description

In a lot of studies from literature was analyzed the influence of antennas on human body. In this article the study reflects the opposite, the influence of human tissue on antennas’ parameters. In this study different types of human tissues are modelled in the vicinity of the patch antenna to analyze their influence on antennas’ parameters. To model the patch antenna, the authors developed and implemented an algorithm dedicated to the determination of the antenna’s geometrical dimensions in terms of dielectrics’ material properties and their standard dimensions, all gathered by the authors in a very useful database. Using our algorithm, we can quickly find the antennas geometrical parameters needed for its numerical modelling and practically construction. The antenna geometry is obtained with our algorithm and next is modelled in the presence of three types of tissue: skin, muscle, and fat. The directivity, S-parameters and specific absorption rate in the tissues are determined, considering different distances between them. Analyzing our results, we can conclude that the normal functioning of the antenna is influenced by the presence of human tissues in their immediate vicinity.
