Dielectric characterization of Borofloat 33 and some classic glasses by the coaxial cable method

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 S
₁₁
, S
₃₃
, S
₁₂
, and S
₃₄
are then extracted. The values of the loss tangent and the dielectric constant are thus measured. We have obtained for the classical glass ε
_r
= 6.5 and tanδ = 0.0206; for the microscope glass ε
_r
= 6.15 and tanδ = 0.021 and at the end for the Borofloat glass ε
_r
= 3.9 and tanδ = 0.012.
