Dear Mr. Baltazar-Lopez,

we have different physical effects. In the kHz range we have some domain

resonance effects and in the MHZ/ GHz range we have crystal dielectric resonance effects.

All the best

Dear Researcher,

You can create some computational models in CST and HFSS software for this study from the point of view of dielectric constant in the kHz to MHz frequency range. I will suggest that you study the following articles and their references:

Thank you CF Yee .

Thank you Kenedy Marconi .

Thank you Frank Gräbner .

Dear Mr. Baltazar-Lopez,

For typical laminate substrates 10% reduction in dielectric constant would be appropriate estimation with frequency increase.
