Dielectric material characterization in the frequency range 68–92 GHz

This work presents millimetre wave measurements of the reflection coefficient for different dielectric materials widely used in our daily life. The measurements (i.e., monostatic measurements) are done by using a frequency modulated continouos wave radar with a dielectric lens antenna. The main results are done for the following materials: Polytetrafluorethylen, Polyvinylchloride, gypsum plasterboard, and autoclaved aerated concrete. The measurements are done in the frequency range from 68 GHz to 92 GHz.
