Fabrication of Human Body Phantom for Body Centric Communication Systems at 2.4 GHz
Keywords:Human body phantom, skin tissue, permittivity, conductivity, dielectric constant
This research is intending to investigate the human skin phantomâ€™s dielectric constant. The phantom will be used to test the electromagnetic compatibility later on since it can be harmful if it is directly tested on real human body. The human body phantom is made to have similar property as a skin tissue, at the operating frequency of 2.4 GHz. A methodology of the process is discussed. The phantom is fabricated, tested and measured. A fabricated phantom with the desired permittivity of Îµr and conductivity of Ïƒ values; are controlled by the amount of polyethylene powder and sodium chloride. The information on dielectric constant of the phantom based on measured values of Îµr and Ïƒ will be determined. The factors in making a good phantom is discussed. A good level of agreement is observed between simulation and measurement results.
