Paper Abstract

Transmission, absorption coefficient, refractive index, real and imaginary parts of dielectric permittivity and loss tangent spectra of polytetrafluorethylene (teflon), Gore-Tex and another teflon based radome memebrane materials are presented as a continuous function of frequency over the range 60-2,400 GHz (5 mm-0.125 mm in wavelength). The new data are better resolved and cover a much wider frequency range. The transmission reduces significantly with increasing frequency for most radomes. The absorption coefficient or loss tangent values increase almost exponentially with increasing frequency for all these radome materials. The refractive index or the real part of permittivity values are alomst similar to teflon since these radomes are teflon based.
