Abstract :
Measured data on the spread in effective permittivity of alumina substrates in the range 1¿18 GHz are presented. The data show both the spread from sample to sample and over the area of a single substrate. Effective permittivities were calculated from the resonant frequencies of open-ended straight-line resonators.
