Design and Performance Analysis of Low Profile Miniaturized MSPAs for Body Centric Wireless Communication in ISM Band

Abstract

Body centric wireless communication is emerging and active area of research for many applications as identification, tracking, health care systems and radio frequency linked telemetry. In this paper, On-body performance and analysis of various wearable square shaped spiral cut MSPAs were investigated by measuring reflection coefficient, radiation pattern and impact of human body equivalent model. This antenna is covering the industrial, scientific and medical band (ISM 2.45 GHz) which can be used for wearable applications in field of health care and telemetry. In particular, the designing and analysis focused on the performance of a miniaturized square shaped spiral cut MSPA for body centric wireless communication. The characterization of proposed antenna is analyzed using numerical equivalent of three layered canonical model of skin, fat and tissue. For all types of wearable square shaped spiral cut MSPA the main parameter under study is reflection coefficient and the effect of novel double C structured square shaped spiral cut MSPA with miniaturized designs.
