Typical Dielectric Parameters of Phantom Material 3-10 GHz

The typical dielectric parameters (relative permittivity and conductivity) of the material used to manufacture dielectric phantoms for frequencies > 3 GHz are provided in the Table below from 3 GHz to 10 GHz. These are values of the base material without the low-loss coating that extends the validity of the mmW phantoms for a good representation of the reflections/absorption of the human body to 110 GHz. The material fulfills the compliance criteria according to [1] from 3 to 6 GHz.
