Abstract
In this paper, a silicon-based antenna for fat-intrabody communication that operates at 5.8 GHz in the ISM band is presented. The bioresorbable, biocompatible, and flexible characteristics of the antenna enable it to be implanted, thus, it can support high-data rate for implantable biomedical application. The antenna design was performed using the Computer Simulation Technology (CST) simulator in time-domain solver and optimized using Trust Region Framework (TRF) optimizer. The antenna transmission coefficient and group delay were investigated as a function of distance between two antennas and the fat thicknesses of the environments in which were immersed in single-layer fat tissue and three-layered tissue (skin-muscle-fat). The simulation results shows that the developed antenna has excellent matching in fat tissue, with great transmission coefficient of −52.4 dB at 150 mm distance, and have a flat group delay between 4.5–7 GHz.
