Characterization and Testing of a Skin Mimicking Material for Implantable Antennas Operating at ISM Band (2.4 GHz-2.48 GHz)

In this study, we present a simple recipe for a skin mimicking material intended for in vitro testing of implantable antennas operating at Industrial, Scientific, and Medical (ISM) (2.4 GHz2.48 GHz) band. The material is composed of de-ionized water, Triton X-100, and Diethylene Glycol Butyl Ether (DGBE). The relative dielectric constant and conductivity of the proposed material are within 0.5% and 3.4% of the properties of the reference human skin from the literature in the entire ISM band. In order to test the transmission characteristics of the material, in vitro measurements of a dual-band antenna are performed.
