Dielectric characterization of Borofloat 33 and some classic glasses by the coaxial cable method
Résumé
In this study, we made the
technical qualification of borofloat 33 glass
and also other much cheaper conventional
glasses, associated with solid metallization
by a broadband characterization method
based on the S-parameters. This made it
possible to extract the electromagnetic
parameters (dielectric permittivity, tangent
loss) necessary for the design and
construction of low visual impact antennas.
The data of these measurement results are
processed. The values of S11, S33, S12, and S34
are then extracted. The values of the loss
tangent and the dielectric constant are thus
measured. We have obtained for the classical
glass εr = 6.5 and tanδ = 0.0206; for the
microscope glass εr = 6.15 and tanδ = 0.021
and at the end for the Borofloat glass εr = 3.9
and tanδ = 0.012.
