发明名称 Multilayer coaxial structures and resonator formed therefrom
摘要 The idea of the invention is to fabricate a multilayer coaxial transmission line into a printed circuit. The outermost conductor is fabricated by conductive conduit strips in different layers, using conductive via posts in isolation layers connecting the strips. The innermost conductor can be a single conductive strip or multiple strips in different layers connected together through conductive via posts.
