Dielectric Constant of Goretex RA7956/7957 Radome Material in the Frequency Range 1 MHz-2 THz

D. Koller, G. A. Ediss, A. R. Kerr

We report on various measurements (capacitance bridge, time domain network analyzer and FTS) of the dielectric constant of Goretex RA7956/7957 radome material over the frequency range 1 MHz to 2 THz. Epsilon_r was found to be between 1.2 and 1.3, somewhat higher than previously determined results.
