Substrate for small patch

Do you know where I can find dielectric with high permittivity (>20) and for a low price ?

Thanks

Ludovic

Do you look for it from Roger Ltd.? If not, pls try it.

Yes, I looked for information from Rogers, but they haven't substrate with permittivity > 20

They should have the material, and can etch the substrates too.
