Comparison of millimeter wave dielectric measurement using various techniques

Four different systems namely the open resonator system, the DFTS, the BWO W-band spectrometer and the broadband free-space measurement system are used to compare the permittivity and loss tangent values obtained when several polymers are measured over the millimeter wave frequencies. Random and systematic error analysis are performed on permittivity and loss tangent values by comparing the dielectric data obtained from the four different systems. Uncertainty analysis is performed on a number of materials as nylon, plexiglass, high-density polyethylene, polypropylene and Teflon. Additionally, systematic error analysis is performed when such polymers as acrylic and fiberglass resin are compared at the W-band frequencies using the DFTS and the BWO W-band spectrometer.
