A Hybrid Skin, Fat, and Muscle Human Body Tissue-Mimicking Biological Phantom and Antenna Testbed

Abstract

Human body tissue-mimicking biological phantoms (bio-phantoms) mimic the electrical and physical properties of actual body tissue and are useful structures for validating wireless thermometer performance. A hybrid bio-phantom testbed designed to operate with an antenna system is presented. The hybrid bio-phantom has realistic dielectric properties and is well matched to the antenna. Reflection properties are validated for an antenna-phantom testbed, and the properties show an accurate prediction for the characteristics of a realistic finite thickness multilayered human body from 0.4 to 3 GHz.
