In this work, 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 of microstrip technology 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 values of S₁₁, S₃₃, S₁₂, and S₃₄ are then extracted on vector network analyzer (VNA). The data of these measurement results are processed and the values of the loss tangent and the dielectric constant are thus measured with ADS software. 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 33 glass ε_r = 4.5 and tanδ = 0.012.
